Patent CA-2214216-A1 (CA)
Title: Utilization of platinum group in diesel engines
Inventor: PETER-HOBLYN JEREMY D
IPC: F02B51/02
Filed: 1996-03-14
Abstract: The invention provides a method employing a fuel additive to improve the operation of a pass-through oxidation catalyst over long periods of time with continued catalytic activity and without the undesirable conversion of SO2 to SO3. A pass-through catalyst support is continuously, selectively catalyzed by the combustion of a fuel containing a platinum group metal composition which bums to release the catalyst metal in active form. The effectiveness of the process is attributed to improved combustion in the engine by the catalyst and the treatment of the catalytic oxidizer with active catalyst metal released during combustion such that, in the exhaust system, the soluble organic fraction of the particulates and the levels of gaseous unburned hydrocarbons and carbon monoxide are significantly reduced. The catalysts conditioned by the present invention cause minimal conversion of SO2 to SO3. The platinum group metal compositions soluble or dispersible in the diesel fuel and are added in amounts effective to provide concentrations of the metal in the fuel of less than 1 part per million (ppm).

Patent CA-2230371-A1 (CA)
Title: Cork extractor
Inventor: PECK JULIAN
IPC: B67B7/04
Filed: 1996-08-28
Abstract: Apparatus comprising a worm (14) that engages with a control nut (9), such that the worm spirals through the nut into the cork (4) on insertion while the nut remains stationary, then the cork is extracted by an upward force on the nut. Mechanical advantage may feature on the insertion and/or extraction processes. Both the upward force and the torque on the worm from the nut are balanced by non-frictional forces from the cork, arising from frictional forces between the bottle (2) and the cork. Having independent insertion and extraction mechanisms enables these mechanisms to be controlled independently and enables the worm to be inserted to and extracted from different depths, depending on the length of the cork. This is not possible in previous nut corkscrews, which rely either on latches at the end of the insertion stroke or on friction between the cork and the worm.

Patent CA-2232615-A1 (CA)
Inventor: BOSSARD BERNARD
IPC: H04B1/74
Filed: 1997-07-09
Abstract: Reliable transmission of signals in a multi-channel system is achieved by transferring signal inputs from a defectively operating or inoperative transmitter to another transmitter which continues to transmit other channels.  At least two transmitters are operated normally, each transmitting its own block of channels. A sensor detects when the output of one transmitter is improper or non-existent, and causes a change-over switch to operate.  Operation of the switch adds the block of channels which had come from the one transmitter to the other (or one or more) of the transmitters, so that the remaining transmitter or transmitters now provide all the channels.

Title: Digital calibration of a transceiver
Inventor: STAAF ANDERS
IPC: H04L27/22
Filed: 1996-12-13
Abstract: Methods and systems for calibrating transceivers are described. Analog transceiver components create errors, such as gain and offset errors in a receiver or a transmitter portion, which are compensated by adjusting digital signal processing in the computing portion of the transceiver. Errors can be measured in a calibration procedure and determined compensating values stored in a memory device of the transceiver. These values can then be retrieved when the transceiver is initialized for usage during signal processing of signals received by and transmitted by the transceiver.

Title: Safety device for a truck wheel
Inventor: NORDINE PETER J
IPC: B60B3/16
Filed: 1998-08-18
Abstract: The invention relates to a safety device for truck wheels. An integral member is provided which is retained in an abutting relationship with the axle of the wheel assembly, but the integral member is free of any connection with the wheel studs of the wheel assembly. The abutting relationship may be provided by having a plurality of holes of the integral member which receive a plurality of the axle studs of the axle. Alternatively, the abutting relationship may be provided by providing a sleeve portion on the integral member and an interior threaded portion within that sleeve that is threaded to the axle of the wheel assembly. A lock screw may then be passed through the integral member to retain the member in the abutting relationship with the axle. An advantage of the present invention is that a strong connection is provided between the axle and the safety device, thus making it possible for the safety device to prevent wheels from flying away from a truck, tractor, or trailer when the wheel studs or rim suffer mechanical failure.
