Title: Logarithmic periodic antenna
Inventor: BRAATHEN RUSSELL
IPC: H01Q1/24
Filed: 1991-07-16
Abstract: ABSTRACT     A logarithmic periodic antenna is constructed with antenna elements implanted in a single plane in or on a surface of an insulating substrate.  The substrate supports the co-planar antenna elements and keeps them in the desired con-figuration.  The antenna elements are arranged in pairs, with the elements of a given pair being on alternate sides of a cen-ter conductor.  The center conductor consists of two conducting strips, or feeders, which run down the middle of the antenna structure.  Each of the feeders connects to a different one of a pair of elements, and each feeder connects to alternating elements of consecutive pairs, for example, to the "left" ele-ment of one pair and the "right" element of the next pair.  The log periodic antennas may be used, without signal degradation, as both transmitting and receiving antennas in split-frequency communications systems.  These antennas, which have minimal back and side lobe amplitudes, may be configured in an array by being mounted on a single mast and at the same height.

Title: Automotive refrigeration system requiring minimal refrigerant
Inventor: SAPERSTEIN ZALMAN P
IPC: F25D17/02
Filed: 1991-11-25
Abstract: ABSTRACT The potential for leakage of CFCs, HCFCs, HFCs and HCs to the atmosphere as a result of leakage in vehicular refrigeration systems is reduced by employing conduits (42, 46 and 52) of relatively short length to interconnect closely grouped system components including a compressor  (38),  a condenser (36) and evaporator flow path (48).  The evaporator (50) also includes a liquid flow path (60) in heat exchange relation with the flow path (48) and the same is connected by conduits (62,  64) to at least one heat exchanger (66,  68) remote  from  the  engine  compartment  (22)  in  which  the compressor  (38),  condenser (36)  and  evaporator  (50)  are housed.  The close proximity of the components minimizes the charge of refrigerant required and thus reduces the amount of refrigerant that may potentially leak from the system.

Filed: 1991-12-18
Abstract: BEARING COOLING ARRANGEMENT FOR AIR CYCLE MACHINE    ABSTRACT      In air cycle machines with hydrodynamic bearings, the mass flow rate of coolant (363 passing through a series of bearings (32, 28, 30) is metered before the coolant passes                     through the final bearing (30).  The final bearing operates at an internal pressure equivalent to that present in the region (72) into which coolant exhausts after exiting the final bearing. Since coolant in the final bearing is at the same pressure as air immediately downstream from the bearing, no rotating seal is required at the outlet of the bearing cooling flowpath.

Title: Echo ranging system
Inventor: NELSON DAVID E
IPC: G01S7/527
Filed: 1992-03-16
Abstract: ECHO RANGING SYSTEM                          Abstract An echo ranging system (FIG. 9) (sonar or radar) measures target velocity and range using a composite Doppler invariant-like signal having at least two segments, such as are present in a "rooftop" or "vee" HFM signal, such composite signal having an ambiguity function with two or more ridge lines of different slopes that intersect along the zero-velocity time axis.  (FIGS. 6, 7, 8)  A distribution of outputs which has an ambiguity function-like character with intersecting pairs of ridge lines is provided by a matched filter processor 16.  The intersecting points of said pairs characterize the range and velocity of the echo returns.  This distribution is adjusted (18) so that the intersecting ridge lines of each pair have equal and opposite slopes with respect to the time axis.  False targets, including clutter and reverberation, are suppressed (20) by subtracting from the adjusted output distribution a replica thereof, folded (rotated) 180° about a time axis containing the intersection of the ridge line pair corresponding to the false target which is to be suppressed.  The rotation and subtraction of the replica from the adjusted distribution provides a set of outputs from which the real target velocity and range can be determined.  A single correlator (38, 40) can be used for each segment, wherein returns from the target are correlated with replicas of each segment of the composite signal to separately transform the Doppler frequency shifts of the target return into outputs whose time relationship provides a frame of reference for high resolution measurement of the velocity of the target.  The time relationship measurement is implemented by a set of tapped delay lines and summers (44) which output a coherent, correlation-like detection peak in a bin which corresponds to the target's velocity, thereby avoiding the need for an expensive bank of correlators (one for each velocity bin) and yielding significant economies.
