摘要: A selective beam splitting arrangement having a plurality of reflective and/or transmissive surfaces for separating incident image-forming light into a number of components to provide more than one image also includes a plurality of additional light sources to provide bias illumination of the image planes. The light from the sources is directed to the image planes by at least some of the same surfaces of the beam splitting arrangement which separate the incident light, at least one of the surfaces being geometrically or spectrally incapable of illuminating all the image planes. The optical axis of the light from each source meets a surface of the beam splitting arrangement in a direction which is substantially a mirror image of the optical axis of the incident light.

摘要: This invention provides an improved mounting or clamping device for optical components such as lenses in which a clamping ring which clamps a component against a shoulder in a mounting body has a deformable resilient lip which bears against the component and which accommodates thermal expansion and contraction in the mounting body, avoiding strain in the optical component. The clamping ring may have a single annular deformable lip or a number of circumferentially regularly spaced apart lips.

摘要: An instrument for testing the profile of a surface of an object having a non-circular, e.g. trochoidal, nominal shape, in which relative rotation is effected betweeen the object under test and the transducer, this relative rotation being compounded of two independent simultaneous rotations about parallel spaced apart axes so arranged that the transducer feeler traces a path which conforms to the nominal shape so that the transducer detects departures from the nominal shape. Automatic correction may be made for changes in the angle of the transducer feeler relative to the surface as the surface is scanned by the feeler.

摘要: A mechanical sampling device for use in liquid analysis systems employs sequentially operated driving means to impart separate components of movement to a sample probe thereby transferring it between work stations. By employment of rotary solenoids as actuators, extreme accuracy of location especially for use in narrow vessels can be achieved in association with speed of operation and accuracy of dwell-time.

摘要: A transducer assembly for a flat diaphragm transducer of the type having a non-magnetic diaphragm with a conductor in the form of spaced parallel strips on one face with a cooperating magnet structure comprising a plurality of elongate alternate magnetic poles, which can be readily assembled by unskilled labour is disclosed. The transducer assembly comprises two polygonal frames having inwardly directed flanges and peripheral upstanding flanges. The inwardly directed flanges serve to define the spacing between the magnet structure and the diaphragm when two such frames are assembled with the diaphragm therebetween and the magnet structures located by the upstanding peripheral flanges of the frame members which flanges project away from one another. The two frame members are clamped along at least two sides in correspondence with the inwardly directed flanges, and the clamping means also holds the magnet structures and a perforated backing plate onto the frame members.

摘要: A switching circuit for enabling a selected one of a number of channels. The circuit includes a number of devices, one for each channel, each having a voltage/current characteristic with a negative-impedance region separating two stable states. The devices are fed in parallel from a source of constant current or constant voltage of a magnitude such that only one may assume one of the stable states. The devices may be for example programmable unijunction transistors or tunnel diodes.

摘要: A mask for use in photolithography and apparatus for using the mask, in which a pattern formed as opaque regions in a transparent mask or as transparent regions in an opaque mask are to be transferred to a photosensitive layer by exposing the photosensitive layer through the mask. Alternatively the photosensitive layer could be exposed to light reflected from the mask if the pattern were formed as variations in the reflectivity of the mask. In order that the mask can be accurately positioned with respect to the photosensitive layer they are both formed with fiducial marks and the fiducial mark on the mask is formed as a plurality of very small elements extending transverse the general line of the fiducial mark and so positioned that diffraction effects at the edges of the elements cooperate to provide a single dense image, that is a single bright image on a dark ground or a single dark image on a bright ground depending on whether the elements are opaque or transparent.

摘要: An apparatus for manufacturing a continuous multi-filament light conducting cable includes a furnace and conveyors having holders thereon for holding rods of light conducting material in parallel relationship. The conveyors move the rods axially and transversely into the furnace to melt the rods in turn into individual light conducting filaments. A drawing means then draws the ends of the melted rods into a multi-filament cable.
