    摘要: An electrical motor includes a stator housing having a toroidally shaped inner cavity. A plurality of stator electromagnets are mounted along the cavity wall in a plurality of parallel helical paths. A plurality of rotor members are rotatively mounted at fixed, spaced-apart angular positions around a ring shaft whose axis is coincident with the axis of the toroidal cavity. Each rotor member includes a plurality of permanent magnets mounted around its circumference. A linear output shaft has one end connected to the ring shaft and its other end extending out of the stator housing. By properly energizing the stator electromagnets, electromagnetic fields set up by them and the rotor magnets interact to produce torque which causes the rotor members to rotate about the ring shaft and to precess laterally causing the ring shaft, and attached linear output shaft, to rotate relative to the stator housing. The toroidal configuration of the motor provides a larger volume electromagnetic field interaction space than conventional cylindrical motors which yields higher output powers and higher torques. The motor, which also has an inherent speed reduction feature, may be operated in reverse as an electrical generator.

    摘要: Small particles are produced by supporting a pair of elongated consumable electrodes coaxially in a housing so that corresponding ends of the electrodes are spaced apart across a gap. A potential difference is applied to the electrodes so that an arc ignited in the gap between the electrode ends gasifies the electrode material at the end. The gas is then cooled so that the gas condenses into small droplets which solidify into solid particles which are collected at a collection site.

    摘要: A toroidal drive system includes a housing composed of first and second mating housing sections having interior walls which cooperate to define a plurality of parallel, helix-like races inscribed in a torus having a circular axis. The two mating housing sections are secured together and a plurality of rotary elements are fixedly spaced apart along that axis, the elements each having an axle fixed at the axis and a plurality of removable, radially extending teeth rotatably encircling the corresponding axle, each tooth of each rotary element engaging in a different one of the plurality of races. A worm is mounted for rotation in the housing about an axis substantially perpendicular to the circular axis, that worm engaging at least one tooth of each of the plurality of rotary elements. Power take off means are connected to all of the axles and extend without the housing. Access holes are provided in the housing section walls at the bottoms of the races, the holes being larger than the teeth engaged in the races so that the housing sections can be mated around the rotary elements while the elements are missing some teeth and secured together after which the missing teeth may be installed on the rotary elements through the access holes by rotating the worm to align the missing tooth positions of the elements with the holes. Methods of making and assembling the drive system are also disclosed.

    摘要: A proofing system incorporates an image member having a dielectric surface and a write head for writing a pattern of electrostatic image dots on the surface. A controller is provided for controlling the write head in response to digital data representing an original document so that the image dots of the pattern may have variable field strengths and form a latent electrostatic image of the document on the surface. The controller also controls the areas of the image dots written on the surface in accordance with the digital data. An inking head presents an electrostatic ink to the surface whereby the surface acquires ink only at the image dots thereon in amounts proportional to the field strengths of the image dots so as to develop the latent image on the surface. A printing substrate is supported and pressed against the image member surface so that the ink is released from the surface to the substrate thereby producing a proof copy of the original document consisting of a pattern of print dots with variable gray scale values and/or sizes so that the system may produce proof copies composed of patterns of dots which emulate the printing structure produced by an offset press or a gravure press.

    摘要: Whitener pigment particles that offer good hiding power consist of particles having a uniform shape (preferably spherical) and varying only slightly in dimension. The particles consist of an inexpensive, readily manufacturable core material which is surrounded by one or more thin, concentric layers or shells, one of which is titania. The core provides the central mechanical support for the shells. In addition to the titania shell, layers can be added to provide compatibility with the carrier in which the particles are dispersed and promote phase transformation. Also described is a production method and apparatus for generating large quantities of the particles.

    摘要: A scanning system for optoelectronically recorded signal patterns stored in a plural layer medium consisting of inorganic materials throughout and featuring a dielectric storage layer at the surface which faces an electron beam source. The source beam first searches for a position mark associated with an image frame on the medium in order to establish a precise home position of the beam and associated coordinate axes prior to commencing the scan operation on that medium frame. Then the beam scans a raster on the medium spending a certain dwell time at each resolution element of the raster. Each time a frame is reached, the system is capable of altering the beam current in response to a pre-recorded exposure code in order to achieve the optimal retrieval of all information stored image-wise within said frame. The system then collects electrons emitted from the medium due to the scanning beam in a collector, which incorporates a highly sensitive amplifier, for further processing, with the medium being movable frame by frame as desired. In another system version, the electronic image on the medium as read using a sensing needle array that scans close to the medium surface making it possible to extract tunnelling electrons through the natural electron surface cloud as a result of an external electrical field applied between the needle and the medium. The "tunnelling current" is modulated by internal, image-wise electrical field domains and the amplitude of the current is representative of the electronic image stored in the medium.

    摘要: An optoelectronic signal recording and storage medium including a base layer, a conductive layer, a photoconductive layer and storage layer has a coherent crystal morphology throughout, even though the chemical and electrical properties of its layers are by choice dramatically different. The base layer is preferably made of monocrystalline sapphire grown in a manner as to allow the growth of the other layers directly on a surface of the base layer without the need to grind and polish that surface, thereby minimizing internal defects in the medium. The monocrystalline base layer also allows the acceptance of exeptionally uniformly distributed charges over wide areas of the medium, thereby enabling the medium to locally record and store minutely differing optoelectronic signals on a background of minimal noise, thus facilitating low light level electronic or optical recording and long term storage of signals and minimal energy readout of those stored signals. The medium base layer can be thin enough to be flexible and transparent and yet to have great strength to provide a firm foundation for the other medium layers. A method of making the medium is also disclosed.

    摘要: Apparatus and method for producing color proofs electrophotographically. A platen carrying an electrophotographic member is translated sequentially past functional stations including a charging station, an exposure station, a toning station, a transfer station and a cleaning station. Once toning is completed, the platen carrying the toner image is translated to the transfer station. An intermediate transfer medium is disposed at the transfer station as the sole receptor of the toner image from the electrophotographic member. A roller effects transfer engagement between the intermediate transfer medium and the toner image carrier. Direct transfer mode or offset transfer mode electively is provided at the transfer station. For offset mode, the toner image on the photoconductive layer involves first transfer to the intermediate transfer medium and from the latter to the transfer medium. The direct transfer mode is effected by employing, as an intermediate transfer medium, the same material as the transfer medium. Successive color separation transparencies are substituted in sequence respectively to form the finished color proof.
