Abstract: Measuring apparatus for calibrating flow meters and the like comprising a piston slidably mounted within piston cylinder means which receives gas passing through the flow meter being calibrated to cause the piston to be lifted. A precision encoder is rotated responsive to the movement of tape means aligned with the central axis of the piston and entrained about a pulley driving said encoder means. The tape is also connected to counterbalancing weight means for enhancing the sensitivity and accuracy of the measuring apparatus. The system electronics initiate operation of timer means upon the first pulse generated by the encoder means after operation of a start button and terminates the operation of the timer means upon the first encoder pulse generated after operation of stop button.Temperature and pressure in the piston cylinder are constantly monitored. These readings are employed at the time flow rate calculations are performed to correct the flow rate calculated to standard temperature and pressure.

Abstract: Apparatus for automatically synchronizing a camera with an electronic flash is provided in accordance with the teachings of the present invention. The inventive apparatus determines if a photographing mode employing an electronic flash has been established by detecting whether or not a power source of the electronic flash is enabled. Upon a detection of a photographing mode employing an electronic flash, an exposure period synchronized with the operation of the electronic flash is automatically established. However, when no electronic flash is to be utilized, an exposure period appropriate to an automatic photographing mode is established.

The operation indicator includes a separate light emitting element located within the finder of the camera to provide a luminous indication within the finder whether a flashlight illumination from the strobo unit has been properly given.

Abstract: The apparatus includes a work supporting table for receiving a glass assembly, and aligning apparatus for properly orienting and aligning the glass panels and spacers of the glass assembly relative to each other and relative to a sealant applying nozzle. A clamping assembly is provided to clamp the glass assembly and maintain it in its properly aligned position so that the sealant material can be applied to the edge of the glass assembly. A sealant applying head is mounted for movement relative to an edge of the workpiece which includes a nozzle assembly for applying sealant material to the workpiece as it moves relative to it. The sealant applying head is driven by a motor and chain arrangement and carries a sensor for sensing the edge of the glass. In response to reaching the end of the glass assembly, the sensor actuates a reversal of the driving motor to reverse the movement of the sealant applying head so that it is returned to its initial position.

Abstract: An optical scanner includes a multi-faceted rotating mirror which reflects light beam from a laser unit, and a condenser lens which focuses the beam as a scanning spot on a scanning surface. An anamorphic optical system comprising a cylindrical lens is disposed between the mirror and the surface, and focuses the beam on the surface in the scan direction, but focuses the beam on a plane short of the scanning surface in a direction perpendicular to the scan direction. An optical element having a magnification of projection which is equal to or less than unity and having a refracting or focussing force only in a direction perpendicular to the scan direction is disposed between the plane and the scanning surface.

Abstract: Apparatus for automatically controlling the position of a device in a cavity includes a light emitter and light sensors disposed in a distal end of the device for determining the position of the distal end within the cavity. When the device is inserted into the cavity, light is emitted from the emitter toward the internal wall of the cavity, and the reflected light is received by the sensors. The reflected light received by the sensors is utilized to automatically control the position of the device in the cavity.

Abstract: The invention describes an electrode assembly for use in a sputtering apparatus.In the sputtering assembly, a cathode mount is insulatingly supported on an anode and carries a target rod. The target rod has a much smaller surface area than the surrounding surface of the anode. High power is supplied to the cathode so that the temperature of the target rod should reach approximately 1000.degree. C. This results in a high rate of sputtering and in the deposition of a pure coating.
