Patent CA-2166229-A1 (CA)
Inventor: NAWATA HIZURU
IPC: H04J1/00
Filed: 1995-12-28
Abstract: In a control system being provided with a local oscillator (42) and being for controlling a demodulating arrangement (43, 44, and 45) demodulating a desired one of modulated signals in accordance with a demodulating frequency, produced by a sweeping operation of the local oscillator, into a demodulated signal having a unique word and an identification number which are carried by the desired modulated signal, a unique word detecting circuit (47) detects the unique word to produce a unique word detection signal.  A number comparing circuit (48) compares the identification number with a desired one of predetermined numbers to produce a number coincidence signal when the identification number coincides with the desired number.  In response to presence and absence of each of the number coincidence and the unique word detection signals, an oscillator control circuit (49) controls the sweeping operation of the local oscillator.

Patent CA-2183718-A1 (CA)
Title: Adjustable mold gate
Inventor: VON HOLDT JOHN W
IPC: B29C45/30
Filed: 1996-08-20
Abstract: A mold gate and a method of using the same, in which the mold gate has an adjustable-area and width, annular access opening to each mold cavity.  As the area is adjusted, the flow of molten plastic to the cavity is controlled for the injection molding of plastic parts.          The adjustment may be made by rotating an outer rotary bushing relative to an inner stationary bushing, which is surrounded by the outer rotary bushing in one embodiment, and which projects beyond it in another.  The position of a hot probe is thus controlled to vary the area of the access opening.  Cooling lines in the vicinity of the hot probe may be provided for significant improvement of operation.  Also, a method is disclosed in which the gate operates  without  closure  by  means  of  metal  parts.          Rather,  the frozen molding compound itself serves to close the gate between mold shots.

Patent CA-2188723-A1 (CA)
Inventor: LEAVITT FREDERICK WELLS
IPC: G01N30/96
Filed: 1996-10-24
Abstract: Ions (e.g. lithium) can be removed or recovered from brines containing those ions and optionally one or more other ions (e.g. other alkali metal ions) by the use of a temperature-swing, ion-exchange process employing an ion-exchange material.  The process depends on a change in the selectivity coefficient of an ion exchange material for the ions desired to be recovered with a change in temperature, resulting in desirable ions being relatively selectively released at one temperature and undesirable ions being relatively selectively released at another temperature.  The process of the invention can be used to effect the separation of any ion (or set of ions) from another ion or from a set of ions wherein the selectivity coefficient for one ion (or set of ions) has a substantial temperature dependence, compared to that for the other ion (or set of ions).
Patent CA-2189648-A1 (CA)
Title: Electronic circuit for determination of distances between reference and data points
Inventor: MARSHALL GILLIAN FIONA
IPC: G06G7/19
Filed: 1995-03-31
Abstract: An electronic circuit for Euclidean distance determination includes two floating gate transistors (M1, M2) connected in parallel. Voltages representing a reference point and its complement are applied to input lines (22, 24) and corresponding charges become stored on the transistors' floating gates (F1, F2). Voltages representing a data point and its complement are input to control gates (G1, G2). The transistors (M1, M2) produce a combined output current which is a quadratic or exponential function of the distance between the data and reference points according to whether the transistors are above or below threshold. The circuit (10) includes a diode-connected load device (M3) for deriving the square root of the output current, which is proportional to Euclidean distance when the transistors are operated above threshold. Refresh means (M44, M45) may be provided for resetting reference points. An array of circuits of the invention is employed for determination of distances between vector quantities.

Title: Deep drilling an/or well pump system using a hydrodynamic retarder to compensate for restoring torques released in the system
Inventor: WEBBER WOLFGANG
IPC: E21B43/12
Filed: 1997-07-15
Abstract: A deep drilling or deep well pump system includes a driving motor, a driven component connected to the driving motor, and a hydrodynamic retarder. The hydrodynamic retarder includes a rotor and stator blade wheel. The rotor blade wheel and the stator blade wheel together form a toroidal working space continuously filled with a working medium during operation of the deep drilling device or the deep well pump device. The rotor blade wheel is continuously connected at least indirectly to the driving motor. The blading of the rotor and stator blade wheel is designed so that, owing to the blade direction in the drive mode, the rotor blade wheel revolves freely. During the occurrence of restoring forces on the driven components, the retarder operates in a braking manner.
Patent CA-2212591-A1 (CA)
Inventor: GUTIERREZ JORGE N
IPC: A61B17/34
Filed: 1997-08-07
Abstract: A trocar including a cannula with a tubular sleeve having a stepped region thereon is disclosed. The stepped region has a plurality of discrete steps. Each step has a step floor and a step support base tapering radially inwardly from the step floor to an adjacent step floor. When the trocar is inserted through the body wall, and the stepped region of the sleeve of the cannula contacts the body wall, the force required to inadvertently pull the cannula out of the body wall when surgical instruments are withdrawn from the cannula increases. Thus, the tubular sleeve of the cannula increases the retention force of the cannula during surgery. The retention force is increased without appreciably affecting the force required to insert the trocar through the body wall. Additionally, these benefits are achieved without using helical threads or externally mounted stability devices, which add cost, complexity and increased risk of causing unwanted tissue trauma.
