Abstract: A rectangular light pipe (38) and associated optical elements (36, 40) are used to produce an overlapped combination of an array of aberrated laser beams (32, 34) inside a phase conjugate mirror (42). The beam array (32, 34) is focussed onto the entrance face (38a) of the light pipe (38) in such a way that each beam (32, 34) spreads by diffraction and internal reflections to fill the exit face (38b) of the light pipe (38). An image of the exit face (38b), which is completely filled by the overlapped beams (32, 34), is focussed into the phase conjugate mirror (42) such as to produce an overlap spot (46) size which is independent of beam aberration level. The apparatus preserves the linear polarization of the input beams (32, 34), has low optical loss, and may be incorporated into a two-pass or four-pass phase conjugate master-oscillator power amplifier.

Abstract: A hydraulically operated dockboard including a ramp which is hinged at its rear edge to the frame of the dockboard, and a lip is hinged to the forward edge of the ramp and can be pivoted between a downwardly hanging pendant position and an extended position. A main hydraulic cylinder unit (9) interconnects the frame and the ramp and by operating the cylinder unit the ramp can be pivoted upwardly from a horizontal cross traffic position to an upwardly inclined position. A lip cylinder unit (10) interconnects the ramp and the lip, and operation of the lip cylinder unit will pivot the lip from the pendant to an extended position. The hydraulic system is constructed so that fluid is initially supplied to the main cylinder unit by a pump (33) to raise the ramp, and when the main cylinder unit is fully extended, the increased pressure will shift a valve (42) to supply fluid to the lip cylinder unit. The valve is constructed so that the valve will be maintained in the shifted position by substantially less pressure than that required to initially shift the valve. When operation of the pump is discontinued, the ramp will descend and the back pressure generated by the weight of the lip acting against the valve will retain the valve in the shifted position to maintain the lip in the extended condition until the lip engages the bed of a truck. 
A valve (24) disposed in a longitudinal passage through the piston (17) of the main cylinder unit prevents a descent of the ramp, if a predetermined downward force is applied to the ramp.

Abstract: A line scanning apparatus includes a cylindrical housing which holds a spin mirror (4), a detector array (8), a multiplexer assembly (34), an analog-to-digital converter (54), a shaft encoder (60), digital processing apparatus and memory storage devices (66). Inertial navigation system (INS) reference information, including velocity-to-height ratio data is provided from the inertial navigation system of the aircraft or other appropriate sensors. The line scanning apparatus further includes optics for focusing radiation which is reflected into the optics by the spin mirror which is inclined at about a 45° angle to the optical axis. The detector array comprises a plurality of radiation detector cells which provide a plurality of synchronously sampled signals representative of the amount of radiation impinging on the detector array at any given time. The spin mirror is attached to a spin mirror motor which is further attached to the shaft encoder. The shaft encoder provides positional data to the digital processing apparatus wherein the positional data represents the spin mirror orientation correlated to a particular period in time. The memory device stores the radiation signals and the synchronous positional data further comprised of array displacement coordinate information which is synchronously correlated to the digital radiation signals. An address control device is arranged to load data into a frame buffer for correction of time delays resulting from the apparent array rotation by compensating for the time delays for applying the displacement information to the corresponding sampled signal. An approximately constant along track swath width per scan results and more readily interpreted imagery results thereby.

Abstract: A distinct conveyor assembly allows a business form sealer (18) such as a pressure sealer -- to operate with forms that have been detached from a continuous supply. Individual forms are detached from the continuous supply while being conveyed in a first direction (19), to form shingled forms having irregularly positioned side edges. The forms are deshingled by conveying them from the detacher (11) at high speed (e.g. an increase in speed of about ten times or more), and they are registered while being conveyed in the first direction at high speed. Registration may take place by moving the forms against one side edge, or moving them between funnelled side edges to ultimately engage straight guides on both side edges. After registration, the forms may be fed directly to the sealer (12), or into the top of a hopper, and then withdrawn from the bottom of the hopper (41) and passed through a folder (40) before being fed to the sealer.

Abstract: A floating sampler and directional bridge for use in characterizing the impedance of an integrated device under test from D.C. up to frequencies above 100 GHz. The directional bridge has the structure of a Wheatstone bridge with resistor values selected such that when the input impedance of the device under test matches the output impedance of the source, no voltage develops across two nodes of the bridge. When no impedance match exists, a floating diode/capacitor sampler comprised of two diode/capacitor pairs (D1, C1 ; D2, C2) driven by local oscillator (147) strobe pulses samples the voltage difference between the two nodes of the bridge and outputs an IF signal proportional to the difference. Another pair of diode/capacitor samples (D3, C3; D4, C4) outputs an IF signal proportional to the amplitude of the RF excitation waveform.
