Inventor: ROWLETT DON C
IPC: E02F9/28
Filed: 1993-05-21
Abstract: A self-sharpening pyramidal shaped insert (24) of a refractory hard metal for use as a leading penetrating element of a soil opener member (10) of an agricultural tool. The insert includes a boss member (44) of a generally frustoconical shape including a circular bottom (46) and outwardly curved side surface (48) extending upwardly from the circular bottom and terminating in a flange (50), and a penetrating tip (58) having four nonparallel triangular sides (60), each triangular side having a common leg with a bordering triangular side and a third leg contiguous with the flange (50). The triangular sides (60) converge to a common vertex. The insert inhibits wear of the agricultural tool and contributes to proper soil flow as the agricultural tool cuts a slice in the soil.

Abstract: A process for casting a pipe such as a delivery pipe with transversal holes, the pipe having an elongate longitudinal hole and at least one pair of transversal holes communicating with the longitudinal hole in a substantially normal direction thereto. The process comprises the steps of positioning a rod-like center pin for forming the longitudinal hole in a predetermined positional relation to a cavity formation surface of a casting die, positioning a pair of mandrel pins for forming the pair of transversal holes such that end faces thereof are in contact with side surfaces of the center pin, and charging molten metal into a die cavity after the center pin and the pair of mandrel pins have been positioned. The molten metal is charged under the condition that the center pin is prevented from deforming by the pair of mandrel pins.

Title: Method and apparatus for automatically switching and charging multiple batteries
Inventor: KOU ABRAHAM H
IPC: H02J7/10
Filed: 1995-01-24
Abstract: A battery selecting and charging system forms part of a portable electronic device, preferably a portable medical device. When the device is powered up, a selecting circuit selects one of two rechargeable batteries to power the device until it is depleted, and then automatically switches to the other battery. When the second battery is depleted, both batteries are selected to power the device. When the device is powered down, a battery charging circuit, having both a high and low charge section, provides a high charge to the battery having the greatest terminal voltage. Thereafter, the high charge is applied to the other battery, the low charge is applied to the first battery, and then the low charge is applied to the second battery. The battery charging circuit monitors the terminal voltage to prevent any damage to the batteries or the device.

Patent CA-2142799-A1 (CA)
Inventor: SHIPPY DAVID J
IPC: G06F12/08
Filed: 1995-02-17
Abstract: A memory system wherein data retrieval is simultaneously initiated in both and L2 cache and main memory,  which allows memory latency associated with arbitration, memory DRAM address translation, and the like to be minimized in the event that the data sought by the processor is not in the L2 cache (miss).   The invention allows for any memory access to be interrupted in the storage control unit prior to any memory signals being activated.  The L2 and memory access controls are in a single component, i.e. the storage control unit (SCU).  Both the L2 and the memory have a unique port into the CPU which allows data to be directly transferred.   This eliminates the overhead associated with storing the data in an intermediate device, such as a cache or memory controller.

Inventor: DORMER MICHAEL J
IPC: F16J15/06
Filed: 1995-05-24
Abstract: A gasket for sealing a fluid environment is made with a metal base or core having an elastomeric coating bonded thereto.  The choice of elastomeric coating and its thickness is determined by the swelling of the elastomer when exposed to the fluid(s) to be sealed.  The swelling supplements the clamping load provided by the bolts, or the like, and provides a better seal by localized swelling which is inverse to the loading.  The gasket coating is preferably fluoroelastomer for a HFC refrigerant lubricant mix.

Abstract: PCT No. PCT/FR94/00177 Sec. 371 Date Oct. 16, 1995 Sec. 102(e) Date Oct. 16, 1995 PCT Filed Feb. 17, 1994 PCT Pub. No. WO94/19624 PCT Pub. Date Sep. 1, 1994A transmission apparatus in which a differential-type transmission device has rotating elements with intermeshing teeth, one of which elements is connected to an input shaft and the other to an output shaft. One of the rotating elements is a reaction element, and the transmission apparatus has a selective locking mechanism mounted operatively between the reaction element and a housing of the transmission apparatus. The selective locking mechanism has a free-wheel for enabling the reaction element to rotate in the same direction as the input shaft and the output shaft when a selective connection device connects the rotating elements of said differential mechanism in order to cause direct drive operation. When the freewheel is locked, the reaction element is integral in rotation with a rotor of a brake which is able to be selectively released in order to release the rotor and the reaction element in relation to said housing. In a neutral condition the brake allows the reaction element to rotate in an opposite direction. The brake is furthermore able to be selectively and gradually activated so as to gradually immobilize the rotor in relation to the housing, whereby the reaction element is then selectively immobilized and allowed to rotate in the same direction as the input and output shafts.

IPC: G06F15/16
Filed: 1995-11-06
Abstract: A framework having a plurality of directories representing different types of middlewares and distributed object systems can be constructed from data provided in a class library. Each directory includes the name and address of all service objects, located across multiple servers in the system, that supports the specific middleware or distributed object policy characteristics for that directory. One service object may be addressed through multiple directories. When a remote method call is issued by a client, a list of service objects capable of executing the call is obtained from the directories and one object selected.  The policy characteristics associated with the directory from which the object address is selected, are attached to the call. These characteristics are validated when the addressed server receives the call. In this way, a client program can be written entirely independently of the middleware or peculiarity of implementation of the distributed object service.

Title: Microbial decontamination system with components porous to anti-microbial fluids
Inventor: MALCHESKY PAUL S
IPC: A61L15/46
Filed: 1995-01-11
Abstract: A countertop decontamination unit (A) has a  decontamination chamber (10) for receiving a tray or module (C) which contains items to be sterilized, disinfected, or otherwise microbially    decontaminated.     The tray or walls of the decontamination chamber itself provide fluid outlets from which an anti-microbial solution is conveyed through tubing (76) to fittings (78). A pump (20) recirculates the anti-microbial fluid. The fittings include a porous sleeve (80, 92) which is received in firm frictional connection with an annular surface of a bore, nipple, or coupler mechaninsm of the item (86) to be sterilized. The porous sleeve is preferably elastomeric when used for frictional interconnections, but may be rigid when used with threaded or other standardized connectors.  The porous sleeve has a porosity of 3 microns or more, sufficient that the anti-microbial fluid penetrates through the porous portion and contacts the immediately contiguous and abutting annular surface. The porous member permits sufficient quantities of solution to contact these surfaces to assure they are microbially decontanimated. Associated surfaces that contact the item and can potentially trap microbes are also constructed of porous material. Other associated porous structures include porous closures, such as plugs (124, 160) or caps (120, 122) which close some of the access ports to the interior passages of endoscopes, item retainers (68), a bottom wall portion (62), other surfaces of the item (174), and the like.
