Title: Method for preventing fraud in an inband signalling telephony system and trunk module realizing such a method
Inventor: DEVOS MARCEL
IPC: H04M1/66
Filed: 1996-03-05
Abstract: The disclosed method prevents fraud in an inband signalling telephony system, such as a No. 5 signalling system. It includes a first step of detecting a fraudulent inband signal at a predetermined location of an outgoing signal path between an input terminal Os and an output terminal Oss of a trunk module T included in the inband signalling telephony system. The predetermined location is situated between the input terminal Os and an injection terminal I of the outgoing signal path where an inband signal can be injected. In a second step, the fraudulent inband signal is removed from the outgoing signal path by interrupting this path during a time interval at least equal to the duration of the inband signal.           The trunk module realizing this method includes a receiver similar to the receivers used in the inband signalling path of the trunk module to detect incomming inband signals and to filter these out before transmitting the signal to a user station connected to the trunk module. This receiver is coupled betwwen the above mentioned input terminal Os and the injection terminal I.

Patent CA-2185746-A1 (CA)
Inventor: CHEN JUIN HWEY
IPC: G10L21/02
Filed: 1996-09-17
Abstract: A speech compression system called "Transform Predictive Coding", or TPC, provides for encoding 7 kHz wideband speech (16 kHz sampling) at a target bit-rate range of 16 to 32 kb/s ( 1 to 2 bits/sample). The system uses short-term and long-term prediction to remove the redundancy in speech. A prediction residual is transformed and coded in the frequency domain to take advantage of knowledge in human auditory perception. The TPC coder uses only open-loop quantization and therefore has a fairly low complexity. The speech quality of TPC is essentially transparent at 32 kb/s, very good at 24 kb/s, and acceptable at 16 kb/s.

Title: Blocking unit for a fallopian tube
Inventor: DOORSCHODT BENEDICT MARIE
IPC: A61F6/22
Filed: 1995-03-20
Abstract: Blocking unit for blocking a Fallopian tube. In order to avoid local anaesthetic and difficulty when inserting such a blocking device into the Fallopian tube and, on the other hand, to ensure sufficient anchoring in the Fallopian tube, it is proposed on the one hand, that the end of the blocking device should be widened and, on the other hand, that it should be such that said widening does not occur until after the insertion into the Fallopian tube. In other words, provision is made for retaining means, in which the widened end is accommodated in the reduced state, which retaining means are rendered inactive after insertion into the Fallopian tube This can be achieved by, for exemple making these retaining means from a bioabsorbable material or an applicator.

Abstract: A low capacitance impedance emulator suitable for active conductor termination.  This impedance emulator includes an emulating FET (12) and a control circuit (16) coupled to the gate of the emulating FET for maintaining the FET in a linear region of operation. The control circuit includes a control FET (20), an impedance setting resistor (22), and an amplifier (24).  The control FET is driven in a closed-loop fashion so that the impedance of the control FET has a known relationship with respect to that of the resistor.  The output of the amplifier controls the conduction of both the emulating and control FETs so that the emulating FET provides an impedance proportional to that of the control FET and thus, related to the impedance of the resistor.

Inventor: MARRIOTT THOMAS J
IPC: F16D3/41
Filed: 1997-03-20
Abstract: A tool for installing and aligning a bearing cap in a universal joint so as to position an end surface of the bearing cap a predetermined distance above the outer surface of the arm of the end yoke is generally cup-shaped, including a generally flat, circular end portion having a hollow cylindrical skirt portion. The skirt portion defines an inner diameter which is slightly larger than the outer diameter of the bearing cap. The skirt portion also defines an axial length which is equal to the desired predetermined distance. A cut-out may be formed in a portion of the tool to receive a spring tab or other axial retaining structure for the bearing cap. Also, one or more apertures may be formed in the end portion of the tool to receive anti-rotation protrusions formed on the end surface of the bearing cap. The universal joint is assembled by initially disposing the tool over the end surface of the bearing cap such that the inner surface of the end portion abuts the outer end surface of the bearing cap. A press is then used to exert a force against the outer surface of the end portion of the tool, urging it and the bearing cap axially inwardly such that the bearing cap is moved over the end of the trunnion until the open end of the skirt portion of the tool engages the outer surface of the yoke arm. The axial length from the inner surface of the end portion of the tool to the end of the skirt portion is sized to be equal to the desired axial distance by which the end surface of the bearing cap extends beyond the outer surface of the yoke arm. The tool provides a quick and easy method for installing the bearing cap on the trunnion and simultaneously aligning such bearings cap at a predetermined location relative to the outer surface of the yoke arm.

Patent CA-2210614-A1 (CA)
Title: Spring cartridge rotor bearing
Inventor: WATSON ARTHUR I
IPC: E21B4/00
Filed: 1997-07-16
Abstract: A spring cartridge rotor bearing is inserted into an electric motor during assembly as a preassembled unit. The rotor bearing includes a sleeve having a bore adapted to receive therethrough a shaft of the electric motor, and each end of the sleeve adapted to contact adjacent motor rotor sections. A bearing has a bore extending therethrough with the sleeve received therein. The bearing thermally locks into the stator bore early in motor warm-up and the bearing has sufficient end play on the sleeve to accommodate shaft expansion. One or more springs are located on the sleeve to bias the bearing to a neutral or generally centered position on the sleeve. The springs permit the bearing to move along the sleeve during times of thermal expansion and contraction, and prevent the bearing from becoming locked into an extreme position. This prevents the transmission of thrust loads from the rotor to the bearing.
