Title: Pill crushing machine
Inventor: SHEWCHUK JAMES G
IPC: B02C19/08
Filed: 2002-02-07
Granted: 2010-02-02
Abstract: Nestable trays are part of a pill crushing device. The trays have cylindrical midportions, spherical end portions and a planar flange. The pill crushing device has an anvil or mortar portion to engage a bottom tray, and a hammer or pestle portion to engage a top tray. The anvil portion has a recess the perimeter of which supports the bottom tray flange. A finger gap is conveniently left in the perimeter for access to the bottom tray. The hammer portion extends between two pivotable lever arms and has sufficient tolerance to allow limited independent movement of the lever arms, which in turn allows relative movement of the trays to crush pills. The hammer can contact the top tray, and may be of cylindrical form with hemispherical ends, which can itself nest in the top tray, in another version it is slightly larger and does not nest but engages the tray near the top. Another hammer version has gripping blocks, separated by a connector tube, which have concave grooves to engage the end flanges of the top tray.

Abstract: Systems and methods are provided for determining subsurface formation properties using an antenna system disposed within a borehole traversing the formation. A logging system includes a well tool implemented with an antenna system having transverse or tilted magnetic dipoles. One antenna implementation uses a set of three coils having non-parallel axes. Through mechanical or electromagnetic rotation of an antenna about its axis in order to maximize or minimize couplings, the systems and methods are used to estimate formation anisotropic resistivity, providing reduced borehole effects in vertical and small deviation wells. This invention may also be applied in deviated wells when the borehole is perpendicular to the strike direction, as is often the case in wireline logging.

Abstract: A fluid pressurizing system and method according to which a fluid at a low pressure is compressed by fluid to increase its pressure to enable it to be discharged from the system and to an external delivery point. The system includes an inlet line (18) for admitting a fluid to a first reservoir (10) via branch (18a) and for admitting a fluid to a second reservoir (12) via branch (18b). After reaching a high level control unit (40), a pump (32) discharges the liquid from the second reservoir (12) to the first reservoir (10). The increased pressure generated in the first reservoir (10) eventually exceeds the downstream pressure at the discharge check valve (24) and the fluid in the upper portion of the reservoir (10) is displaced from the reservoir (10) into and through the discharge flow line (22) for delivery to an external point.

Title: Facsimile data transmission over a low data rate network with fill bit removal and reinsertion
Inventor: PROPACH DAVID S
IPC: H04N1/411
Filed: 1994-11-15
Granted: 2004-10-26
Abstract: System and method for minimizing data bottlenecks in Low Data Rate Networks (LDRNs) that communicate facsimile transmissions. An LDRN is a facsimile network having a transmission data rate less than the data rate of the FAX machines serviced by the network. The system and method can be implemented in any type of LDRN, including analog and digital wired LDRNs, as well as analog and digital wireless (e. g., cellular) LDRNs. The system and method involve processing the facsimile transmissions in order to make the data rates of the LDRN and the FAX machines compatible, thereby minimizing any potential facsimile data bottlenecks that may occur in the LDRN due to its slower data rate.

Title: Powered liftgate opening mechanism and control system
Inventor: FERRIMAN LARRY J
IPC: B62D25/10
Filed: 2002-04-25
Granted: 2006-10-24
Abstract: A power-operated system (32) for actuating the rear doors or liftgates (18) of motor vehicles (10) is disclosed. The system includes a strut assembly having two struts (30), each strut mounted on one side of the door between the door and the vehicle's door frame. One end of each strut (30) is connected to a powered moving arm (40). To open the door, the arms (40) move to change the angular orientation of the struts (30) such that they have a substantial mechanical advantage. In this position, the force provided by the struts (30) overcomes the weight bias of the door (18), thus opening the door. To close the door, the moving arms (30) change the angular orientation of the struts (30) such that the struts have a decreased mechanical advantage, reducing the force provided by the struts, and therefore allowing the door (18) to fall closed under its own weight bias. A control system for controlling the power-operated system (32) is also disclosed.

Title: New synergetic compositions of vitamins, minerals and trace-elements to stimulate the elimination of intra-cellular lipid deposits
Inventor: SHRIVASTAVA RAVI
IPC: A23L33/00
Filed: 2003-10-22
Granted: 2012-01-03
Abstract: Nearly 40% population of the developed countries in the world have the problem of excess weight. Up till now, no correlation was established between the deficiencies of certain specific vitamins , minerals and trace-elements with the problem of excess weight. None of the weight reduction strategies proposed till today took into consideration the reduced capacity of the cells to eliminate the intracellular lipid deposits which is the real cause of excess weight.   After many years of research, we discovered that a synergetic composition of certain specific vitamins, minerals and trace-elements stimulate the intracellular lipid elimination capacity of cells thereby helping to reduce body weight in a very short period of time without any side-effects and without the rebound effect often observed at the end of the dieting period. The methods of preparation of such solid or liquid compositions for oral or topical application are known.   These synergetic compositions can be used either alone or in association with products commonly used to reduce weight, with specific diets, with apparatuses for physical exercise or muscular electrostimulation which are commonly employed to increase energy loss.
