Abstract: A surgical extractor (10) for removing calculi, such as kidney stones and gall stones, from the body. The extractor includes a handle (11) at a proximal end (12) of the extractor with a slider (14) for operation by a physician. At the distal end (16) the extractor includes a plurality of pairs of wires (15) with portions of each pair being formed along the turn of a helix. When a retaining sheath (17) is retracted, the wires, formed of a shape memory material such as stainless steel, expand such that each pair of wires closely assumes a path along a helical turn with individual wires remaining closely adjacent. This use of plural wires for each strand multiples the number of contacts with entrapped calculi and can be provided without any deleterious effect on the reliability or size of the extractor.

Title: Method and apparatus for verifying compatibility between modular components in a computer system
Inventor: LILLICH ALAN W
IPC: G06F9/06
Filed: 1994-05-03
Abstract: The invention is a method and apparatus for verifying compatibility between components of a system which share a client-provider relationship. Briefly, according to the invention, a current version of a provider and a compatibility range are defined for each of a version of a client and a version of a provider. A version of a provider specifies an oldest implementation provider and an oldest definition provider. When a client is linked with a particular version of a provider, it stores an identification for that provider, a current indicator for that version of the provider, called a definition provider, and the oldest implementation provider. At runtime, compatibility checks are performed between a client and available versions of the provider(s), called implementation providers, with which it has been linked. For each available version of each type of provider compatibility exists with the client in three situations. First, if the definition provider and the implementation provider are the same version of that provider, then the client and provider are compatible.  Second, if the definition provider, i.e. the version of the provider linked with the client, is newer than the implementation provider, then if the version of the implementation provider is no older than the oldest implementation provider specified in the client, the two are compatible, otherwise they are incompatible.  Third, if the definition provider is older than the implementation provider, then if the definition provider is no older than the oldest definition provider specified in the implementation provider, then the two are compatible.

Patent CA-2167015-A1 (CA)
Inventor: CESHKOVSKY LUDWIG
IPC: G11B7/12
Filed: 1996-01-11
Abstract: An apparatus for controlling the spacing between information tracks while recording information on an optical disc that does not have pre-manufactured information tracks. The invention employs a reference scale to precisely determine the position of information tracks to be recorded on an optical disc, wherein spacing of optical tick marks on the reference scale directly correlates to track pitch between information tracks recorded on the optical disc. The invention utilizes a first optical system for reading-from and writing-to an optical disc. A second optical system is used for detecting optical tick marks on the reference scale. The first optical system and the second optical system share common optical components, and are used in cooperation with control means to direct an optical pickup to a desired location of the optical disc for recording an information track thereon.
Patent CA-2167109-A1 (CA)
Inventor: CHARLTON STEVEN C
IPC: G01N35/00
Filed: 1996-01-12
Abstract: A sensor dispensing instrument is adapted to receive a generally circular sensor pack containing a plurality of blood glucose sensors. Each of the sensors are disposed in sensor cavities, each of which is in fluid communication with a corresponding desiccant cavity and has a support wall that assists in directing the sensor as its being ejected from the cavity. The sensor pack is loaded on an indexing disk in the instrument such that when a slide actuator on the instrument is moved toward a testing position, a feed mechanism engaged by the slide actuator moves a knife blade thereon toward one of the sensor cavities. The knife blade pierces a portion of a foil covering the sensor cavity and engages the sensor disposed in the cavity to thereby eject the sensor from the sensor cavity. The continued sliding of the slide actuator toward its testing position results in the sensor being completely ejected from the sensor cavity and disposed in a testing position with a testing end of the sensor projecting from the instrument. Once the blood analyzing test is completed, the slide actuator is moved in the opposite direction towards its standby position. As the slide actuator is moved away from its testing position, the indexing disk with the sensor pack thereon is rotated so that the next one of sensor cavities is positioned so that the sensor therein can be used for the next blood glucose test that is to be performed. The instrument includes circuitry to obtain test data from the sensor pack and to display testing data.

Title: Superconducting rotor
Inventor: JOSHI CHANDRASHEKHAR H
IPC: H02K9/20
Filed: 1994-09-14
Abstract: The superconducting rotor (10) includes at least one field coil (12) made of a superconductor material having a given superconducting transition temperature. A cryocooler system is mounted for rotation with the rotor (fig. 2). The cryocooler includes a cold head portion (24) mounted in heat transfer relation with the field coil (12) to cool the field coil to a temperature below its transition temperature and includes a piston/regenerator (42), (figs. 3, 4 and 5) adapted to allow passage of a working fluid at a mass flow rate which is substantially uniform over the cross section of the piston/regenerator during the operation of the system. Heat is conducted away from the field coils (12) by heat pipes (80) or by conduction through high thermally conductive material. Mounting the cryocooler cold head (24) for rotation with the rotor eliminates the use of a cryogenic liquid pool for rotor cooling.

Title: Mechanism for feature improvement for bicycles and other crankdriven mechanism
Inventor: VEILBERG UFFE STEEN LAWAETZ
IPC: B62M1/36
Filed: 1994-09-05
Abstract: In the case of bicycles, the purpose of the new construction is to make maximum use of the momentum produced by pedalling under varying ground conditions, load, and acceleration--thus making bicycling easier. The construction has two variable positions which reduce the time during which the pedals are in a dead position (top and bottom) and prolong the time where the pedals are at right angles (16) whereby maximum effect is gained from the power force. This applies if the direction of force is non-circular, i.e. when there is a rise of the ground, and under acceleration as well as "standing pedalling". New positioning is possible in relation to the pedal arm (18), i.e. when changed ground conditions (rise) cause the center of gravity (pedalling) to shift. The invention differs from existing ones in that them is "increased"  angular velocity between the driving shaft (1) and driven shaft (2) when they are on the same level and have the same longitudinal direction, which is the easy in this construction. Also, the special suspension obtained by means of three moving rings (3) (4) (5) (like cardan suspension) of which the change of angle and vertical position (4) of the second ring together with the manually controllable parts (16) (18) produce the above-mentioned increased angular velocity and its position in relation to a given center of gravity. (9) shows an exterior bearing.

Title: Probiotic for control of salmonella
Inventor: NISBET DAVID J
IPC: A61K35/745
Filed: 1994-12-13
Abstract: A defined probiotic or composition of anaerobic bacteria effective for controlling or inhibiting Salmonella colonization of fowl. The probiotic includes populations or cultures of 29 substantially biologically pure bacteria. In use, the probiotic is administered to the subject fowl in an amount effective for increasing resistance to Salmonella colonization thereof. The invention also relates to a novel method for isolating probiotics which are effective for controlling or inhibiting Salmonella colonization of domestic animals, from fecal droppings, cecal contents or large intestines of the adult animals. The droppings, cecal contents or large intestine are combined with a culture medium and incubated without dilution (i e. batch culture) under anaerobic conditions. Following this preliminary incubation, the resultant culture is subjected to continuous flow conditions until a steady state is achieved, after which time the steady state culture may be recovered for use as a probiotic.
