Patent CA-2294097-A1 (CA)
Title: Decelerator device mounted in the exhaust gas circuit of a vehicle equipped with a combustion engine
Inventor: WAGNER PIERRE-ANDRE
IPC: F02D9/06
Filed: 1999-04-22
Abstract: The invention concerns a decelerator device for obtaining constant and maximal decelerating power whatever the engine speed, by controlling the pressure of the gases upstream of the valve by balancing the efforts at the actuator cylinder rod. The decelerator device (1) is characterised in that it comprises a balancing device (25) incorporated in the actuator cylinder (9) and comprising the cylinder rod (12) dissociated from the piston (11) and a calibrated spring member (26) mounted between them. When the valve (7) is closed and, based on a counter-pressure predetermined by the spring member calibration, the actuator rod (12) moves back by stroke C' which causes the valve (7) to open by an angle  alpha  generating a leakage of the exhaust gases. Beyond said threshold, the valve (7) reopening angle varies according the exhaust gas pressure thereby ensuring a constant and maximal counter-pressure whatever the engine speed. The invention is applicable to combustion engines and in particular to industrial vehicles.
Patent CA-2294895-A1 (CA)
Title: A subscriber unit and method for use in a wireless communication system
Inventor: ODENWALDER JOSEPH P
IPC: H04J13/10
Filed: 1998-06-30
Abstract: A set of individually gain adjusted subscriber channels (A, B, C, Pilot) are formed via the use of a set of orthogonal subchannel codes (Walsh+-, Walsh++-) having a small number of PN spreading chips per orthogonal waveform period. Data to be transmitted via one of the transmit channels is low code rate error correction encoded and sequence repeated before being modulated with one of the subchannel codes, gain adjusted, and summed with data modulated using the other subchannel codes. The resulting summed data (316) is modulated using a user long code and a pseudorandom spreading code (PN code) and upconverted for transmission. The use of the short orthogonal codes provides interference suppression while still allowing extensive error correction coding and repetition for time diversity to overcome the Raleigh fading commonly experienced in terrestrial wireless systems. The set of sub-channel code may comprise four Walsh codes, each orthogonal to the remaining codes of the set. The use of four sub-channels is preferred as it allows shorter orthogonal codes to be used, however, the use of a greater number of channels and therefore longer codes is acceptable. Preferably, the pilot data and control data are combined onto one channel. The remaining two transmit channels are used for transmitting non-specified digital data including user data or signaling data, or both.

Title: Process for improving shelf stability of liquid overbased calcium carboxylates, mixed metal stabilizers containing same, and stabilizing halogen-containing polymers therewith
Inventor: LABOVITZ BENJAMIN PAUL
IPC: C08K3/26
Filed: 1998-08-24
Abstract: Shelf stable liquid overbased calcium carboxylates are prepared by reacting a calcium base with a monocarboxylic acid, and carbonating in the presence of a promoter mixture with a phenol and an alcohol under controlled temperature conditions, to produce shelf stable liquids.   Mixed metal stabilizer compositions are prepared by blending the stable liquid calcium carboxylate with a metal carboxylate of zinc, cadmium or tin.

Title: Wave flame control
Inventor: HAZARD GARY M
IPC: F23C15/00
Filed: 1998-11-25
Abstract: A burner system (10) is provided which creates standing waves (Fig. 6) in the gas/air flow within the burner so as to vary the pressure distribution along the length of the burner and thus the heights of the flames produced along the length of the burner. By changing the standing waves, the pressure distributions within the burner are changed, thereby causing the burner to produce changing flame patterns that simulate realistic wood burning flame patterns. In another embodiment (Fig. 5), two orthogonal or sinusoidal gas/air flows offset by a phase angle are generated within the burner creating a beat frequency. By varying the phase angle offset, the rate of occurence of the beats defining the beat frequency are varied resulting in the variation of the pressure distribution within the burner. Consequently, the flame patterns generated by the burner are varied simulating the appearance of realistic wood burning flame patterns.

Title: Method of manufacturing a semiconductor device with a field effect transistor
Inventor: SCHMITZ JURRIAAN
IPC: H01L21/28
Filed: 1999-09-09
Abstract: In the known replacement gate process, the relatively high-ohmic poly gate is replaced by a low-ohmic metal gate by depositing a thick oxide layer and subsequently planarizing this layer by CMP until the gate is reached, which gate can be selectively removed and replaced by a metal gate. The process is simplified considerably by providing the gate structure as a stack of a dummy poly gate (4) and a nitride layer (5) on top of the poly gate. When, during the CMP, the nitride layer is reached, the CMP is stopped, thereby precluding an attack on the poly. The nitride and the poly are selectively removed relative to the oxide layer (10).
