Title: Apparatus for stacking bolts
Inventor: DIKA MICHAEL
IPC: B65B27/10
Filed: 1989-11-30
Granted: 1995-12-12
Abstract: The stacker comprises a receiving bin adapted to position bolts close to the ground in an orientation that is perpendicular to the direction of advance of the stacker.          The bin has side walls that closely confine the two ends of the bolts.  A reciprocating plunger at the base of the bin biases the bolts rearwardly through an aperture into a stacking bin that trails the receiving bin.  The stacking bin is open at the rear and at the bottom.  Its parallel side walls closely confine the ends of the bolts collecting therein.  The bolts biased rearwardly by the plunger are forced into the base of the stack in the stacking bin.  The combination of the resistance of the ground-engaging stack, the confinement by the side walls,  and the  forced introduction of bolts into the base of the stack, induces a "boiling up" action of the bolts at the front end of the stack whereby they self-align themselves into a parallel state.  When the bins are moved ahead, they leave behind an elongated stack of bolts.

Title: Processor controlled circuit breaker trip system having reliable status display
Inventor: DURIVAGE LEON WILLIAM III
IPC: H02H3/16
Filed: 1990-08-22
Granted: 1995-12-26
Abstract: A fault-powered, processor-based  circuit breaker tripping system employs a reliable low power trip indicator circuit that is normally powered from the tripping system.  A liquid crystal display is used to indicate the status of the system, and a battery is used as a secondary power source after a trip terminates the power to the system.  The battery is enabled by a manual switch or by a latch which responds to one of a plurality of trip signals from the processor.  The latch also provides signals to a driver circuit to drive the LCD. Once enabled, the battery provides power to the latch and the LCD so that the cause of the trip may be displayed during a power fault.  The manual switch can be used to select status signals to be displayed on the LCD, and to indicate the condition of the battery.  The LCD includes a segment for indicating that the system is energized and power is being drawn from the current path but that amount of power is below all fault levels and insufficient to operate the system.

Title: Screw conveyor
Inventor: LEHMANN ROLF
IPC: B65B1/12
Filed: 1991-09-13
Granted: 1995-04-04
Abstract: A screw conveyor with a slowly rotating feed screw for precision metering by conveying very small amounts of loose material between screw threads, the same amount of loose material being discharged from the end of the conveyor with eachturn of the screw. During the relatively short time interval of a single revolution, which can last one minute or even a multiple thereof as needed, the conveyor capacity itself fluctuates, since discrete amounts of the material being conveyed are always delimited by the individual threads of the feed screw. In order for a screw conveyor to be usable for precision metering of very small amounts to be conveyed, i.e. for conveying very small amounts with a high degree of constancy without the periodicity caused by the nature of the feed screw, the screw conveyor is provided with a rotatably mounted tube surrounding the discharge end of the fixed feed tube and which is driven at a rotational speed proportional to the rotational speed of screw.

Title: Medical member and method of manufacturing the same
Inventor: OGAWA KAZUFUMI
IPC: A61L33/00
Filed: 1992-01-24
Granted: 2001-08-28
Abstract: A medical member having active hydrogen groups such as hydroxyl, amino or imino groups at its surface, is dipped, either directly or after formation of an inner layer on its surface, into a solution. The solution is prepared by dissolving a surface active material, e.g., CF3 (CF2)7 (CH2)2SiC13 in a non-aqueous solvent. A dehydrochlorination reaction is brought about between active hydrogen groups at the surface of the member and SiCl groups of the surface active material, thus producing bonds of CF3 (CF2)7 (CH2)2Si (O-)3 over the entire surface. A fluorine-containing monomolecular film is formed, which is chemically (or covalently) bonded to the member surface and has a thickness at the nanometer level.      Since the chemically adsorbed film is covalently bonded to the member or inner layer, it is chemically stable and difficult to separate. Excellent medical members can be obtained When the invention is applied to an artificial tooth, a joint, a bone, a blood bag, a catheter, a blood transportation tool, a dialysis equipment part, an operation thread, a medical implant and an operation tool.

Title: Well rig lift system and a hydraulic energy-storing well rig lift system
Inventor: XINYI GU
IPC: E21B19/08
Filed: 1992-12-10
Granted: 2000-03-28
Abstract: A well rig lifting system and a hydraulic energy-storing well rig lifting system, wherein a high pressure energy-storing cylinder and a composite cylinder or cylinder group are used to carry out the lifting and lowering operations. During the lifting operation, a power machine under a substantially constant load continuously pumps oil to the energy-storing cylinder, and communication relationships of the energy-storing cylinder with various chambers of the composite cylinder or cylinder group is selected to provide an appropriate lifting force to lift the pipe string. Therefore, the installed capacity of the power machine can be reduced to 1/3-1/4 of that in a conventional lifting system. During the lowering operation, communication relationships of the energy-storing cylinder with various chambers of the composite cylinder or cylinder group is selected to provide an appropriate lifting force grade less than the gravity of the pipe string, so as to utilize the energy-storing cylinder to recover the potential energy released during the lowering of the pipe string. The recovered energy can then be used to carry out auxiliary operations during the lowering operation, and therefore no power machine is needed to run. The recovered energy can also be used in power generation, heating, etc.
