Title: Automatic adjustment of receiver apparatus based on channel-bit-error-rate-related parameter measurement
Inventor: WALKER GORDON K
IPC: H04H20/00
Filed: 1993-06-29
Abstract: AUTOMATIC ADJUSTMENT OF RECEIVER APPARATUS BASED ON CHANNEL-BIT-ERROR-RATE-RELATED PARAMETER MEASUREMENT            ABSTRACT OF THE DISCLOSURE   Alignment of an antenna and a polarizer for the antenna are automati-cally adjusted and the frequency setting of a frequency-tunable receiver is automatically adjusted while receiving a broadcast communication signal that is forward-error-correction coded by processing the forward-error-correction code of the received signal to measure a channel-bit-error-rate-related parameter for the received signal; by realigning the antenna and the polarizer from their respective initial positions in response to the measured parameter until the measured parameter is minimized: and by retuning the receiver from its initial frequency set-ting in response to the measured parameter until the measured parameter is min-imized. A Viterbi decoder processes the forward-error-correction code of the received signal to compute path metrics related to the bit-error rate of the received signal and normalizes the computed path metrics: and a counter counts the nor-malizations over fixed intervals to measure a path metric normalization rate as the measured parameter.

Title: Push-push ring resonator oscillator
Inventor: FIEDZIUSZKO SLAWOMIR J
IPC: H03B1/04
Filed: 1993-11-02
Abstract: A push-push microwave oscillator has two branch oscillators fabricated of a transistor and transmission line elements extending from terminals of the transistor, and a resonator which is fabricated of an annulus of superconductor material and serves to phase lock oscillations of the two branch oscillators. The superconductor material is a composite of a rare earth element and copper oxide such as yttrium-barium-copper oxide. A first transmission line in each of the branch oscillators extends past the resonator with a spacing to provide for electromagnetic coupling between the branch oscillator and the resonator. A second transmission line in each of the branch oscillators has a length equal to approximately one-quarter wavelength of the oscillation frequency to tune the branch oscillator to a common oscillation frequency. A third transmission line in each of the branch oscillators extends towards a junction point to form a summing unit for summing oscillations of the two branch oscillators to provide an output signal of the oscillator. The oscillator is constructed in stripline or microstrip form wherein components of the branch oscillators are coplanar with the resonator and are spaced apart from a ground plane by a dielectric layer of alumina or lanthanum aluminate. Power is extracted at an even multiple of the fundamental frequency, and has a improved accuracy of frequency and reduced phase noise, the latter arising because of a characteristic of the superconductor material wherein its microwave surface resistance increase proportionally with a square of an increase in frequency.

Abstract: A trolling lure includes multiple spoons or spinners attached in series along a flexible cable leader. The spoons or spinners may be of the same size or of different sizes, and the leader also includes several series of plastic or glass beads along the leader to provide color. Some of the beads may also serve as bearings for the rotational action of the spoons or spinners. Spacing of the spoons or spinners, beads, and other components is achieved by crimping or swaging sleeves onto the multiple strand cable leader at various points. The spoons or spinners are preferably of aluminum, to provide relatively light weight for slower trolling speeds, and are preferably provided with a somewhat porous surface by weathering, knurling, or abrading the surface. The porosity thus achieved provides a more realistic and less reflective surface, and further provides better retention of a fish attracting scent thereon.

Title: Gun powered by pressurized gas and/or pressurized air
Inventor: EBERT GARY F
IPC: F41B11/60
Filed: 1994-05-24
Abstract: A gun can be powered by a cartridge of pressurized gas or by pressurized air.  The gun includes a valve body which provides a pressure reservoir for storing pressurized gas or air.  When the gun is fired, pressurized gas or air is discharged from the pressure reservoir and propels a projectile out of the barrel of the gun.  An air pump is mounted on the gun for supplying pressurized air to the pressure reservoir.  An adapter assembly is mounted on the gun for holding a cartridge of compressed gas.  The adapter assembly includes an adapter housing and a plunger which is slidably mounted in the adapter housing.  The plunger is movable between a sealing position in which the plunger sealingly engages the adapter housing and an exhaust position in which pressurized gas or air from the pressure reservoir can flow out of the adapter housing.  The plunger is maintained in the sealing position by a gas cartridge or by a plug which can be screwed into the adapter housing.  A check valve in the plunger permits pressurized gas to flow through the plunger into the pressure reservoir but prevents pressurized gas or air to flow from the pressure reservoir through the plunger.
