Title: Electronic controller for linear cryogenic coolers
Inventor: NELSON ARTHUR RANDALL
IPC: F25B9/14
Filed: 1996-09-24
Granted: 1999-07-20
Abstract: A highly efficient motor driver circuit of an electronic controller for linear cryogenic coolers operates directly from a variable power supply, such as a batter, without the need for the voltage regulator control circuit of the prior art.      Elimination of the prior art voltage regulator ensures a higher efficiency motor driver circuit of the electronic controller. Both open-loop and closed-loop controllers electronically control the motor driver circuit. The open-loop controller protects against temperature sensor failure, and will limit maximum motor power as a function of system ambient temperature. The closed-loop controller regulates the temperature of the cold finger accurately to a preset value, using feedback from a temperature sensor along with a novel pulse-width modulation concept for modifying motor drive waveforms. The motor driver circuit provides the advantages of increased efficiency, operation from a variable power source, tight control of temperature regulation, a fail-safe mode of temperature sensor feedback, and a small envelope space enabling electronic controller mounting internal to the cooler motor/compressor assembly of a linear cryogenic cooler.

Title: Feed waste detector
Inventor: MOLAUG OLE
IPC: A01K61/60
Filed: 1995-11-08
Granted: 2004-01-20
Abstract: A method and a device for detecting fodder waste/loss within a fish enclosure (1), where a sound transmitter (4) and a hydrophone (6) are disposed as an upwardly directed echo sounder close to the bottom of the enclosure (1). Sound echos from objects situated above the sound transmitter (4), are picked up by the hydrophone (6). A measuring unit (8) separates signals from the hydrophone (6) into various frequency bands close to the transmitted sound frequency. The distance and amount of the objects are determined in a way similar to the one used in echo sounders. Sinking objects will cause reflected sounds having frequencies slightly higher than the transmitted frequency, so called Doppler effect, and the frequency difference is a measure of the sinking speed of the object. An analyzing unit (10) emphasizes frequencies corresponding to a characteristic sinking speed for the actual type of fodder (2) and gives signals about fodder waste/loss when a predetermined minimum amount of objects having the characteristic sinking speed are detected within a predetermined distance area.

Abstract: A system for electronically powering an acoustooptic device. A radio-frequency (RF) generator supplies RF drive power at a drive carrier frequency. A signal source delivers a modulating signal. An RF modulator modulates the RF drive power with the modulating signal. Two compensating RF power generators supply high-frequency and low-frequency compensating power at frequencies greater than and less than the drive carrier frequency. Operational amplifiers and modulators modulate the compensating power with signals derived from the signal source such that the modulated compensating power is the complement of the modulated RF drive power. A summer combines the modulated RF drive power and compensating power to drive the acoustooptic device such that the spatial thermal energy distribution inside the acoustooptic device remains substantially constant.

Granted: 2003-12-02
Abstract: Method and compositions are provided for analyzing nucleic acid sequences based on repeated cycles of duplex extension along a single-stranded template. Preferably, such extension starts from a duplex formed between an initializing oligonucleotide and the template. As illustrated in the figure, the initializing oligonucleotide is extended in an initial extension cycle by ligating an oligonucleotide probe to its end to form an extended duplex. The extended duplex is then repeatedly extended by subsequent cycles of ligation. During each cycle, the identity of one or more nucleotides in the template is determined by a label on, or associated with, a successfully ligated oligonucleotide probe. The invention provides a method of sequencing nucleic acid which obviates electrophoretic separation of similarly sized DNA fragments, and which eliminates the difficulties associated with the detection and analysis of spacially overlapping bands of DNA fragments in a gel or like medium. The invention also obviates the need to generate DNA fragments from long single-stranded templates with a DNA polymerase.

Title: Folding table
Inventor: HILL STEVEN J
IPC: A47B21/00
Filed: 1996-05-30
Granted: 2001-06-12
Abstract: A folding table (1) with a table top (5) and a pair of breakaway legs (15) supporting the top. A brace member (47) at each end of the table has a leg assembly (7, 9) attached thereto. A top supporting beam (11) extends along the table top between the brace members. The support beam is pivotally mounted to the table top. Each leg assembly has a hinge structure (35) near its top end and a foot structure (24) at its bottom end. The hinge (35) allows the leg (15) to break down and fold inwardly against the table top. A pair of leg braces (81, 83) is attached to the support beam and are moveable with the beam. Each leg brace is removably attached to a corresponding leg by a locking assembly (87). When the leg braces (81, 83) are attached to the leg, they transfer downward force from the table top to the legs at a point below the hinges (35) to keep the legs in the unfolded position. The locking assembly (87) can be disengaged and the leg braces pivoted out of the way to allow the legs to be folded. A wire gallery (13) is removably attached to the leg braces (81, 83) below the table top.

The leading (46) and trailing edges (48) of the fins (22, 22') are contoured to substantially conform to isotherms around the circulating fluid flowing within the tubes (12, 12'). To achieve this edge configuration while also allowing for a dense packing of fins and tubes in a multi-row heat exchanger, the leading and trailing edges are wave shaped such that adjacent fins can interfit together.

Title: Beam-type axle suspension system
Inventor: DILLING SCOTT ALLEN
IPC: F16F1/38
Filed: 1997-08-27
Granted: 2001-04-17
Abstract: An air-ride beam-type axle suspension system for tractor-trailers and other heavy-duty wheeled vehicles having a brake chamber of an air brake assembly mounted on the beam, wherein the beam is tapered. Specifically, each beam of  the axle suspension system tapers from a narrower width at its end that is pivotally attached to a frame rail of the trailer, to a wider width at its opposite end. The wider width of the beam enables a slack adjuster of the brake assembly to be disposed within the confines of the beam and still be accessible for repair, removal and/or replacement, without requiring an acce ss cutout in the beam which could potentially weaken the beam structure. The tapered beam also provides, at its wider portions, efficient support for the  axle and air springs of the suspension system, easier mounting of the suspension system on existing trailer frame rails and incorporation of a reduced-size pivot bushing at the narrower end of the beam, and optimizes th e weight of the axle suspension system.
