摘要： An improved dual-stage pump system is provided for the accurate pumping and filtering of viscous fluids. Two hydraulically activated pumps are provided in series with a filter and reservoir disposed in-line between the two pumps. The reservoir acts as a source bottle for the second pump and allows the first pump to pump the viscous fluid through the filter at a rate independent of the dispensing rate of the second pump. By operating the first pump at a rate independent of the second pump, back pressure at the filter is avoided. Each hydraulically activated diaphragm pump is equipped with an improved diaphragm that is pre-formed to the geometries of the process fluid cavity thereby eliminating any inaccuracies in the operation of the pumps due to expansion of retraction of the diaphragm during pump operation.

摘要： A system synchronously controls the advance of a recording medium or may be employed in a facsimile recording apparatus in which a modulated optical information beam is caused to scan or be swept across the recording medium as the medium is advanced in a stepwise manner. For this purpose, digital control circuitry including a programmable read only memory responds to a galvanometer synchronization signal, indicative of the beginning of a scan line, and selectively generates stepping motor advance signals in accordance with a look-up table stored in the memory as the beam scans the recording medium. By this action, the location in each successively recorded line at which the recording medium is stepwise-advanced is aligned in the direction of movement of the recording medium with a corresponding advance location for every other line irrespective of the rate of advance of the medium. As a result, banding, which would otherwise contribute to degradation in the recorded image copy, is effectively eliminated.

摘要： An automatic antenna tuner which conjugately matches the impedance of an electrically small antenna to the impedance of a transmit amplifier output stage by using a pi-type impedance matching network with adjustable capacitive circuit components which are preferably implemented using a low cost escapement mechanism. During an initial set up tuning procedure, a resistive Wheatstone bridge detector is disposed between the output of the power amplifier and the input to the pi network, to feedback a measure a degree of match of the pi network to a controller. The capacitive elements in the legs of the pi network are then electromechanically adjusted under the operator of the controller until an optimum setting is found. These initial impedance values are determined for each frequency in an operating range and then stored in a non-volatile memory. As a second step in the tuning procedure, a fine adjustment is made to the stored optimum impedance values just prior to transmission, to accommodate changing environmental conditions and the like.

摘要： A high resolution scanning system, employing non-linearly driven galvanometer deflection optics, compensates for both the non-linear rate of travel of the information pixel beam and for pixel position offset introduced by an optical subsystem (a flat field lens) that equalize pixel size and quality across the recording medium. The system employs a single high speed reference clock the output pulses of which are counted and used to address a compensation data-containing PROM (programmable read only memory). The contents of successive addresses of the PROM contain pixel location codes identifying the position on the recording medium where a pixel of interest is to be recorded. These codes are derived in accordance with the periodic non-linear rate of travel of the scanning optics across the recording medium and the measured parameters of a flat field lens disposed in the path of the scanning beam. For a sinusoidal scan, the successive PROM addresses contain pixel location defining codes that are effectively compensate for the non-linearity of the sinusoidal scan rate of the galvanometer deflection drive and the image position offset introduced by the flat field lens optical subsystem. Because of this complementary action, the spacing between pixels can be made constant along a recorded line of pixel data.

摘要： A fluid bearing platen for a film gate structure contains a pair of cavities to which pressurized fluid, such as air, to be applied against the opposing surfaces of a photographic film, is supplied. Between each respective cavity and one side of the film there is disposed a thermodynamically non-throttling material, such as porous stainless steel, through which the pressurized fluid from the cavities passes, to be directed against the opposite sides of the film. The non-throttling material effectively creates an adiabatic transfer from the cavities to the film's opposing surfaces, thereby eliminating temperature loss and avoiding the wrinkling or warpage of the film.

摘要： A film supporting and positioning system includes a film holding or gripping head for engaging an edge portion of the film and supporting the same in a cantilever fashion. The gripping head may include a frictional contact gripping arrangement or a vacuum head by which the film is held along one edge thereof. The gripping head is displaceable in a plurality of orthogonal directions so that the film may be inserted into and oriented relative to the image plane of an optical recording/reproducing system. In the vicinity of this image plane, a film support bearing is provided, in order that a prescribed region of the film, in which information may be recorded may be properly irradiated by a light beam. Preferably, the film support bearing is provided by a fluid bearing platen which is thermodynamically non-throttling.

摘要： A corrosion resistant check valve having plastic components in the fluid path is provided. The check valve broadly comprises an inlet housing, an outlet housing, a valve poppet, and a spring. The inlet housing has an inlet passageway and the outlet housing has an outlet passageway. The inlet housing and outlet housing are connected to define an internal chamber of the check valve. An inner portion of the inlet housing has a transverse wall which includes a valve seat surface and a central hole which defines a flow passageway between the inlet passageway and the internal chamber. The valve poppet is disposed within the internal chamber and has a disk-shaped body and a stem extending perpendicularly outward from a centerpoint of the body. The stem of the valve poppet is positioned in a central bore in a planar end surface of the spring. The planar end surface of the spring also includes fluid flow passages disposed about the central bore. In operation, the spring biases the valve poppet into sealing engagement with the valve seat surface to control fluid flow from the inlet passageway into the internal chamber. When the fluid pressure in the inlet passageway exceeds the biasing force of the spring, the valve poppet unseats from the valve seat surface and fluid flows around the valve poppet, through the fluid flow passages in the spring and out of the outlet passageway.
