Title: Centering the rim of a wheel on its supporting hub
Inventor: LUPYRYPA RAYMOND L
IPC: F16B5/02
Filed: 2000-04-06
Abstract: A method of centering a wheel rim on a wheel hub of a vehicle is provided where the hub includes a center projection arranged to engage a central hole in the rim to effect a centering action and a plurality of threaded wheel support studs carried on the hub in a pattern surrounding a central axis of the hub. The method includes providing three or four female threaded fasteners each for engaging onto a respective one of the studs for clamping the rim to the hub. Each fastener has an integral body defining a sleeve portion and a nut portion with a female thread through a central bore. The sleeve portion is inserted between the cylindrical inner surface and the threaded portion of the stud as a sliding fit inside the cylindrical inner surface so as to accurately locate the hole relative to the stud for centering the rim on the hub and the nut portion clamps the rim to the hub. The fasteners are spaced angularly around the hub and conventional nuts are engaged onto the remaining studs to hold the rim in place. When held the centering fasteners can be removed.

Inventor: WEINS BENJAMIN ISAAC
IPC: B25B13/46
Filed: 1999-06-03
Abstract: A ratcheting open-ended wrench (20) has a movable jaw (30) pivotally attached to a fixed jaw (32). The jaws (30, 32) define an opening (28) capable of receiving the hexagonal head (H) of a fastener such as a nut, bolt, hose fitting or pipe fitting. The fastener may be turned by moving the handle (22) of the wrench (20) back and forth without disengaging the fastener's head (H) from the opening (28). A stop (59) prevents the movable jaw (30) from moving in a way which would place excessive stresses on the movable jaw (30). An arc shaped bearing surface (62B) on the movable jaw is received in a mating bearing surface (62A) on the fixed jaw. The combination of the stop (59) and the mating bearing surfaces (62A, 62B) greatly reduces shear forces on the pivot (36). The point about which the movable jaw pivots is located forwardly relative to the opening (28).

Abstract: The present invention provides novel radiopharmaceuticals useful for the diagnosis of infection and inflammation, reagents and kits useful for preparing the radiopharmaceuticals, methods of imaging sites of infection and/or inflammation in a patient, and methods of diagnosing diseases associated with infection or inflammation in patients in need of such diagnosis. The radiopharmaceuticals bind in vivo to the tuftsin receptor on the surface of white cells which accumulate at the site of infection and inflammation. The radiopharmaceuticals are also useful for imaging tumors and treating the cancer by delivering a cytotoxic dose of radiation to the tumors.  The radiopharmaceuticals of the present invention are comprised of one to three pentapeptides, X1X2X3X4X5, independently attached to a metal chelator or bonding moiety, Ch, to which is attached a Tc-99m, Re-186, or Re-188, optionally further comprising a linking group, Ln, between the peptides and the chelator or bonding moiety. The pentapeptide sequence binds to the tuftsin receptor and is attached at the N-terminus to Ln or Ch. The interaction of the pentapeptide recognition sequences of the radiopharmaceuticals with the tuftsin receptor on white blood cells results in localization of the radiopharmaceuticals in sites of infection and inflammation, and in tumors.

Patent CA-2339334-A1 (CA)
Inventor: O'DONNELL PATRICK
IPC: H02G3/08
Filed: 2001-03-02
Abstract: A support bracket and extra-low voltage control device for installation with an electrical outlet box provides the capability of attaching or removing extra-low voltage (normally 30 volts or less) control of AC power (normally supplied at 120 volts) circuits such as lights. A controlling device in an enclosure (also called a control module) is attached to the exterior of one wall of an electrical outlet box, so that AC  120 volt wiring from the control module AC controlling device (a relay, a triac or a transistor) enters the electrical outlet box through an aperture in the wall of the electrical outlet box. Extra-low voltage control wiring enters the control module through an aperture in the control module enclosure and connects either to a relay coil or to an opto-coupling device within the control module enclosure to provide physical separation between the two wiring systems. Optionally, the control module used may receive a radio frequency signal or a power line carrier signal and in these cases opto-coupling and extra-low voltage wiring are not required. The support bracket is attached to a joist or a wall stud so that the electrical outlet box, when attached to the support bracket, has an open wall flush with the interior face of the drywall. The electrical outlet box is attached to the support bracket in a removable fashion and this allows the electrical outlet box with the control module attached and AC building wiring attached to be withdrawn from the wall or ceiling cavity to allow access to the extra-low voltage wiring (when present) and access to the control module for maintenance or removal. The same control module can be used with recessed lighting fixtures that have access to their connection box without requiring the use of the support bracket.

Title: A vehicle presence detection system
Inventor: BADER CLIFFORD J
IPC: G08G1/16
Filed: 1999-08-06
Abstract: A system (22) and method which can detect the presence of a vehicle within the protected area (32) of a four gate railroad crossing (30), determine its location and direction it is moving in, and open an appropriate exit gate to allow the vehicle to escape prior to the arrival of a train at the crossing.  The system has a series of magnetometer sensors (41-46) suitably placed in the crossing to detect the presence of a vehicle. The sensors are connected to a controller (23) which analyzes readings from the sensors. Upon the approach of a train, the controller, based on analysis of readings from the sensor, determines if a vehicle has become entrapped and determines which exit gate (35 and 39) must be opened or should remain open to allow the entrapped vehicle to escape. The system also has self test capabilities as well as the ability to continuously update, when no vehicles are present, a baseline reading of the ambient magnetic condition of the crossing area, which baseline the controller uses in analyzing data from the sensors.

Title: Inhaler
Inventor: SCHMIDT HUGO DINES
IPC: A61M11/00
Filed: 1999-09-24
Abstract: An inhaler for delivering medicament by inhalation, comprising a housing for holding a canister of medicament having a body and a valve stem compressible together to actuate the canister to deliver a dose of medicament from the valve stem, an actuation mechanism for compressing the canister, a cannister re-set mechanism comprising a locking element for locking the canister in a compressed state and a release member resiliently biassed by the actuation mechanism on compression of the canister to release the locking mechanism to allow reset of the canister. By provision of the locking element for locking the canister in a compressed state, it is possible to ensure re-set does not occur immediately. The release member subsequently releases the locking mechanism to allow re-set of the canister after a proper dose has been delivered. The cannister reset mechanism further comprises a damping element for damping movement of the release member to delay the action of the resilient biassing to release the locking element a predetermined period of time after actuation of the canister.
