Title: Selenium composition for application to soils and pastures
Inventor: VOERMAN MICHAEL J
IPC: C05D9/02
Filed: 1991-05-15
Granted: 2000-09-12
Abstract: This invention provides a selenium composition that may be applied to pastures and soils to treat selenium deficiency in soils, plants and grazing animals. Known formulations use either sodium selenate or barium selenate in a slow release form. However these known compounds either are not sufficiently long-lasting or cannot rapidly boost selenium levels in pastures. These problems have been overcome by an agricultural composition that has an effective amount of a mixture of barium selenate in a slow release form and a water soluble selenium compound. The ratio, on the basis of elemental selenium, of water soluble selenium compound to barium selenate is between 10:90 and 30:70. The composition is able to provide a selenium boost and maintain selenium levels in pastures for long periods.

Title: Correcting the horizontal deviations of an elevator car during vertical travel
Inventor: ROBERTS RANDALL K
IPC: B66B7/04
Filed: 1992-03-11
Granted: 1998-06-30
Abstract: Elevator horizontal vibrations are actively controlled by retrieving data stored in memory indicative of the out-of-straightness of the elevator car's guide rails.  The stored data is compiled during a learning run by summing the car's relative displacement with respect to the rail with a doubly integrated acceleration signal indicative of the car's deviation from true vertical.

Title: Laser-based wheel alignment system
Inventor: MADEY JOHN M J
IPC: G01B11/275
Filed: 1990-06-21
Granted: 2000-10-03
Abstract: A device and method to align the wheels of motor vehicles. A beam of collimated light from a low power visible laser is slit into two generally parallel beams by a partially transmitting mirror and series of plane front surface mirrors positioned in front and along side the vehicle being serviced. The two beams are reflected from a set of plane mirrors attached to the rims of the wheels to be aligned. The vertical and horizontal angles of each of the wheelmounted mirrors are set by calibrated lead-screws to cancel the angular displacement of the wheels expected when the wheels are properly aligned. The reflected beams are imaged through a large aperture beam combiner on a common viewing screen. Correct toein and camber settings are indicated when the laser beams reflected from the wheel-mounted mirrors overlap at the center of the viewing screen. The caster settings of the front wheels are measured by observing the angle at which the reflected spots travel across the screen when the steering wheel is turned the system can be used to align the front wheels only, or alternatively all four wheels simultaneously:

Filed: 1991-02-27
Granted: 1996-10-29
Abstract: The present invention provides a method for treating or preventing certain metabolic disorders comprising the administra-tion of 3-guanidinopropionic acid (3-GPA). These metabolic disorders of human and animal metabolism, e.g hyperglycemia, im-paired glucose tolerance, hyperinsulinemia and insulin insensitivity, hyperamylinemia, excess adiposity, and hyperlipidemia, may occur in the following disease states: non-insulin dependent diabetes mellitus (NIDDM), obesity, hypertension and atherosclero-sis. 3-GPA may be administered admixed in the diet of farm animals or as a pharmaceutical preparation such as an oral tablet or capsule, by injection, or by implantable sustaind release devices thereby increasing the protein content of the carcass while de-creasing its fat content. This would produce muscle tissue with less fat.

Granted: 1996-03-19
Abstract: A tentering machine having a compliant drive link allows for a considerable rate of stretch in a tentered fabric, web  or  film without the  distortion  or bowing  frequently observed with the tentering machines of the prior art.  The tentering machine includes two conveyor tracks adjacent to and facing one another, each conveyor track having a number of fabric edge holders slidingly directable thereabout.  A fabric, web or film, grasped on opposite edges by the fabric edge holders, is conveyed thereby through the tentering machine in the  space  between  the  two  conveyor  tracks.    Widthwise stretching occurs where the conveyor tracks of the tentering machine have sections on each side of the fabric which diverge from one another, while the two conveyor tracks may be parallel to each other on the two sides of the fabric in applications where prevention of shrinkage is of interest.  The fabric edge holders on each conveyor track are run at a substantially common speed by drive chains.  Elongated, spring-like compliant drive links extend from the drive chains to the fabric edge holders, but are not connected thereto.  The compliant drive links allow adjacent fabric edge holders to move relative to one another, permitting a considerable rate of stretch without the distortion or bowing of the fabric, web or film observed during the use of prior-art tentering machines.

Abstract: In a frequency synthesizer, a first pulse removing circuit (31) is connected between a reference signal generator (21) and a phase-frequency comparator (24).  A second pulse removing circuit (32) is connected between a variable frequency divider (23) and the phase-frequency comparator.  Responsive to first removing data indicative of a first pulse number, the first pulse removing circuit removes pulses from the reference signal that are equal in number to the first pulse number for a first predetermined cycle to produce a first pulse removed signal.  Responsive to second removing data indicative of a second pulse number, the second pulse removing circuit removes pulses from the divided signal that are equal in number to the second pulse number for a second predetermined cycle to produce a second pulse removed signal.  Responsive to a current command, a current controlling circuit may control current supplied from/to a charge pump circuit (25).  A control circuit may be connected between the phase-frequency comparator and the charge pump circuit.  A switch may be inserted between the loop filter and the voltage controlled oscillator.  When the switch switches off a PLL, a D/A converter supplies a control voltage to the voltage controlled oscillator and a filter capacitor of the loop filter.  The charge pump circuit may comprise a control circuit, a constant current circuit, an integrating circuit, and a sample and hold circuit.

Abstract: Extraction of liquid/gaseous material for reclamation is effected into a container by reducing the temperature of the container to a sufficiently cold temperature to generate a vacuum within the container sufficient to extract the material from the system to be extracted. The container is cooled by placing the container into an insulated drum containing a glycol bath within which is provided an evaporator duct shaped with a plurality of separate duct portions lying in horizontal planes and spaced vertically with each portion interconnected to the next by a vertical section of the duct. Into the duct is injected carbon dioxide from a compressed liquid supply which is passed through a metering orifice tuned to the length and shape of the duct so that evaporation takes place by the end of the duct. Any liquid remaining at the end of the duct as the temperature cools is returned by a diverter valve into the glycol bath for additional cooling effect.
