Title: Stokes injected raman capillary waveguide amplifier
Inventor: KURNIT NORMAN A
IPC: H01S3/30
Filed: 1979-08-31
Granted: 1982-04-20
Abstract: Abstract of the Disclosure A device for producing stimulated Raman scattering of C02 laser radiation by rotational states in a diatomic molecular gas utilizing a Stokes injection signal.  The system utilizes a cryogenically cooled waveguide for extending focal interaction length.  The waveguide, in conjunction with the Stokes injection signal, reduces required power density of the C02 radiation below the breakdown threshold for the diatomic molecular gas.  A Fresnel rhomb is employed to circularly polarize the Stokes injection signal and C02 laser radiation in opposite circular directions. The device can be employed either as a regenerative oscillator utilizing optical cavity mirrors or as a single pass amplifier.          Additionally, a plurality of Raman gain cells can be staged to increase output power magnitude.  Also, in the regenerative oscillator embodiment, the Raman gain cell cavity length and C02 cavity length can be matched to provide synchronism between mode locked C02 pulses and pulses produced within the Raman gain cell.

Abstract: Abstract of the Disclosure A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame.  At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system.  Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%.  The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time, temperature and pressure.    Each individual modular press can be multi-opening and has the ability to open and close on command.  Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface.  The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets.  At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings.  The loading apparatus is pivotally mounted.  Also provided is an aligning apparatus for ensuring proper alignment of each veneer sheet within its respective opening after being loaded.  The modular presses in one embodiment are mounted on a carousel frame structure that is rotatable on a main bearing so each modular press indexes past the loading and unloading stations.

Abstract: ABSTRACT         A self-standardizing pressure sensor for use with an electronic fuel control system of an internal combustion engine.  The sensor includes a body having first and second external ports for sensing manifold absolute pressure and ambient atmospheric pressure, respectively. An internal valve within the body is biased to normally register with the MAP port, but is actuatable to register with the AAP port,  The valve in-cludes an internal passage which communicates whichever of the ports is selected to an internal pressure chamber.  One wall of the chamber is defined by a flexural diaphragm. Flexing of the diaphragm is transmitted to an electromechanical transducer which produces an output signal repre-sentative of the pressure in the internal chamber.  A normal force bias is applied to the diaphragm, but is temporarily removed by actuation of the internal valve to effectively unload the diaphragm to permit standardization of the sensor.

Abstract: ABSTRACT OF THE DISCLOSURE           A binary coded signal is converted into pseudoternary coded form not by a complicated amplitude-modulation technique, but instead by application to a combination of flip-flops and logic gates.  A clock pulse train, to which the binary coded signal is phase synchronized, is used to generate component pulse trains some of whose signal elements have only one half the duration of the bits of the binary coded signal.  These component pulse trains are then combined to form the pseudoternary coded signal, in which some bits of the binary signal are represented by combinations of signal elements each having only half the bit duration and different respective ternary logic levels.

Abstract: LIQUID CIRCULATING DEVICE          ABSTRACT      An apparatus is provided for causing circulation within a large body of fluid.  The apparatus comprises a "large bubble" generator exposed to the pressure of the fluid at a predetermined level, a vertically extending standpipe, an inverted siphon between the standpipe and the generator, and a transverse connection between the standpipe and a vertically extending stackpipe.  Upon generating a large gas bubble into the stackpipe, the gas acts as a piston within the stackpipe, pushing liquid upwardly there-through, and thereby drawing liquid into the bottom.  The continuous passage of such large bubbles through the stackpipe results in a current flow circulation through the large standing body of liquid.  The advantage of the present type of large bubble generator, is that the generator can be placed at a position beneath the surface of the standing body of liquid  a distance limited only by the rapidity at which a large bubble can be generated, as it is desirable that in steady state operation, a large bubble enter the stackpipe before the preceding large bubble has exited from the top.

Abstract: Abstract of the Disclosure An ornamental wheel cover for ornamental removable attachment to an automotive wheel comprises a rim portion hav-ing a retention means.  The retention means gripingly engages the wheel.  A central portion is disposed axially outward from the rim portion and has a central aperture therethrough.  The aperture is in axial alignment with the axle upon which the wheel is rotatably mounted.  A locking pin is slidably dis-posed within the aperture and has a head portion at its out-ward facing end and a reduced portion at the inward facing end terminating in a radially extending pin member.  The head por-tion is positioned outboard of the central portion of the wheel cover and captures a string member between the central portion and the inward facing radially extending portion of. the head portion in combination with a funnel shaped member provided with a radially projecting collar.  The radially pro-jecting collar has a hole therethrough for registration on the threaded studs to which the wheel is fixedly mounted to rotate with the wheel.  Nuts positionally lock the radially project-ing collar on the studs wherein the central axis of the funnel member is coincident with the axis of the axle and the locking pin.  The funnel shaped member flares inwardly to surround the end of the axle and terminates in a truncated conical portion. The truncated conical portion has a slot therethrough for re-ceiving the radially extending pin member end of the locking pin when the locking pin is pressed inwardly against the bias-ing force of the spring member.  The radially extending pin member engages an outwardly facing detent formed on the inner surface of the truncated conical portion and is positioned perpendicularly to the slot provided through the truncated conical portion.  The detent is semi-circular and has sub-stantially the same radius of curvature as the radially pro-jecting pin member such that the locking pin is lockingly positioned when the radially extending pin member comes to rest in the semi-circular detent thereby positively locking the wheel cover to the funnel member and, in turn, to the wheel member.
