Abstract: FOCUSSED DOPPLER RADAR                Abstract of the Disclosure An optically focussed laser radar operating with a radi-ation wavelength of typically ten microns is focussed on an object to be observed.  Doppler data is obtained with a contin-uous wave signal by mixing a reference of the transmitted signal with a signal reflected from airborne scattering centers. The system is particularly useful for clear air turbulence applications wherein aerosols such as dust and pollen serve as the scattering centers for reflecting the radiation.  The radar converts to a pulse Doppler system when the depth of field exceeds the desired range resolution.

Abstract: IMPROVED METAL VAPOR LASER DISCHARGE TUBE     ABSTRACT OF THE DISCLOSURE An internal mirror metal vapor laser, and in particular, a helium-cadmium laser discharge tube, which is economical, compact and has a relatively long op-erating and shelf life, the operating life typically exceeding 10,000 hours. A positive column helium-cadmium laser tube of the consumable type and having optical resonator mirrors integral with the tube ends to hermetically seal the tube is provided which includes a relatively large volume cadmium reservoir capable of containing sufficient cadmium for operating life times exceeding ten thousand hours. A heater is applied to the cadmium reservoir for controlling the cadmium vapor pressure. The helium pressure is actively controlled by releasing helium from a high pressure helium reservoir when the helium pressure is less than a predetermined value. This is ac-complished by providing a signal representing the sensed pressure of the helium in the laser discharge tube and comparing electronically this signal with a signal representing the pressure of helium at a desired operating condition (reference pressure).

Abstract: GEAR PUMP WITH MEANS FOR DISPERSING GAS INTO LIQUID            Abstract A gear pump for dispersing a gas into a liquid is provided with mixing means for improving the uniformity of the dispersion.  In preferred form, the mixing means comprises a series of fixed, shallow, blind cavities that open to the pump-ing cavity between the liquid inlet and the outlet, and which are positioned to be "wiped" by the gear teeth as the gears rotate.          The alternate connection and disconnection of the intertooth spaces to these cavities as the gears rotate establishes motion or turbulence of the gas/liquid mixture within the intertooth spaces, and surprisingly improves uniformity of the dispersion.

Abstract: RACK AND PINION TEETH CONFIGURATION     ABSTRACT OF THE DISCLOSURE The present invention relates to the gear configuration between a pinion and a rack.  The pinion forms a plurality of teeth which are received In respective grooves on the rack.  The teeth each define a pair of flanks which oppose a pair of surfaces within the groove and the flanks and surfaces substantially define circular arcs.  The radius of curvature of the circular arc for the surfaces is slightly larger than the radius of curvature of the circular arc for the flanks.  A separating force is generated between the pinion and the rack when rotation of the pinion imparts transverse movement to the rack and the circular arcs of matching surfaces and flanks cooperate to substantially eliminate the separating forces after slight separa-tion between the pinion and the rack.

Abstract: ABSTRACT           The coke oven recuperator consists of concentric inner and outer steel tubes adapted to be located, by means of an adjustable packing, vertically in the bottom wall of a recuperator chamber of a recuperative coke oven.  Combustion air is introduced into the inner tube via an inlet from outside the chamber and emerges from the inner end of the tube and is turned back by the closed end of the outer tube so as to flow down the annulus between the inner and outer tubes where it picks up heat from the waste gases which are fed down through the recuperator chamber from a chamber inlet to a chamber outlet.  The heated combustion air flows out of the recuperator via an expansion chamber and outlet to individual heating flues of coke ovens.  The recuperator provides a recuperative coke-oven having better fuel consumption.

Abstract: BINARY VAPOR CYCLE METHOD OF POWER GENERATION                        ABSTRACT A binary vapor cycle method of electrical power genera-tion is disclosed wherein two refrigerant fluids can be used to operate an apparatus for the generation of mechanical power as well as electrical power generation.  This method, which is essentially a dual heat pump system, offers an approach to utilizing the advantages of two different refrigerants within a single apparatus.  This advantage is particularly advantageous in the utilization of low specific energy sources, such as two water sources which exist in close proximity to each other, but at different tempera-tures.  Thus, water, which itself is a heat pump fluid, can be used as a means of transmitting heat energy to a second heat pump fluid, or refrigerant, without incurring the disadvantages of water or water vapors as its high specific volume and low saturation pressures at low temperatures. The utilization of barometric legs to bring the warm water, such as ocean water, into contact with the process, elimi-nates the use of expensive heat exchangers, which in the case of ocean water, are subject to fouling and loss of efficiency due to clinging microorganisms.

Abstract: ABSTRACT         Suction tube packages consisting of suction tubes wrapped in protective envelopes, which with the help of adhesive tapes are joined to a coherent "rope-ladderlike" band, are used to facilitate the mechanical handling and the application of the wrapped suction tubes to packing containers. The suction tube bands are difficult to manu-facture with high accuracy, since the suction tubes sur-rounded by the protective envelopes, owing to their un-defined, varying contours, are difficult to orientate in correct position on the adhesive tapes.         In accordance with the invention it is proposed to manufacture the protective envelopes as well as the tapes joining them at the same time and of the same material. The suction tubes are placed with equal intervals transversely between two thermoplastic webs, whereupon these are sealed to each other around the suction tubes. At the same time the webs are punched or cut so that individual suction tube enve-lopes are obtained which are mutually connected by means of straps extending between the envelopes. In this manner all handling of separate wrapped suction tubes is avoided, so that the suction tube band can be manufactured with appre-ciably greater precision. The invention relates to the method of manufacture as well as to a machine for its realization and the finished suction tube band.

Inventor: HABIGER CYRIL W
IPC: F16K11/07
Filed: 1980-06-10
Granted: 1982-10-26
Abstract: Control Valve With Improved Centering and Detent Mechanisms Abstract Conventional directional control valves and the like normally include relatively complex and spatially separated centering and detent mechanisms for selectively maintaining a valve spool at centered and detent-held positions, respectively.  Such valves are normally bulky and the casings therefor, primarily since they require machining, cannot be manufactured by die-casting methods.  The above problems are overcome by providing for the precise positioning of a valve spool in its centered position by interassociating and engaging a centering mechanism with a detent mechanism by a stop, defined on a retainer of the detent mechanism.

Abstract: ABSTRACT       A simplified short backfire directional antenna provides both sum and error radiation patterns in the H-plane. Three parallel dipoles are mounted above a pan-type reflector, with a small metal reflector disc over the dipoles.  The center dipole is excited to produce a sum pattern and the two end dipoles are excited out of phase to provide an error pattern with a broadside null in the H-plane.  Alternatively, a hybrid circuit may be used with a pair of parallel dipoles to generate the desired patterns.  Improved gain and resolution are achieved with a small antenna array.
