Patent CA-2018400-C (CA)
Title: Electrical connectors
Inventor: TAKANO TSUNESUKE
IPC: H01R13/516
Filed: 1990-06-06
Granted: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE      Electrical connectors include a base (preferably formed of a plastics material) having an upright retaining wall.  An electrically conductive bus plate has a base portion disposed adjacent a forward surface Or the retaining wall so that a male terminal projects forwardly therefrom.  A tubular housing is coupled to the base forwardly of the retaining wall via resilient tongue structures, and includes an opening through which the male terminal extends.  When mounted to the base, a rear wall of the tubular housing will forcibly press the base portion of the male terminal against the retaining wall so as to rigidly hold the male terminal positionally within the tubular housing.  In such a manner, the electrical connectors of the present invention minimize (if not eliminate entirely) distortion and/or positional skewing of the male terminal.  A female plug body having female terminals may thus be inserted within the tubular housing so that the male terminal and female terminal are mated thereby establishing electrical communication with an external circuit, for example.

Title: New carrier catalyst for the polymerization of ethylene
Inventor: ALA-HUIKKU SIRPA
IPC: C08F4/654
Filed: 1990-09-04
Granted: 1998-11-24
Abstract: A problem in the conventional olefin polymerization catalyst systems, the procatalysts of which are based on a solid carrier and a titanium compound and an electron donor on its surface, is that unsufficiently high activities are achieved by the morphology of the carrier. Moreover, the active age of such a catalyst in the polymerization is too short. These problems have now been solved by the olefin polymerization catalyst system according to the invention, the procatalyst of which comprises a solid carrier and a layer on its surface consisting of a titanium compound, a magnesium compound and an electron donor. The advantages of the invention become more emphasized when using monocyclopentadienyl titaniumtrichloride as the titanium compound.

Granted: 1996-06-25
Abstract: A thermally balanced electronic circuit having an element mounted on a suitable support base, a heat-sink having a bottom portion contacting the element and at least one flange projecting from the bottom portion, and a stress-balancing insert positioned on the bottom portion of the heat-sink and at least partially coextensive with the element, said bottom portion of the heat sink being secured to the element and to the insert by means of an adhesive. The insert is of a material having a coefficient of thermal expansion (TCE), .alpha.1, different from the TCE, .alpha.2, of the heat sink. The TCE of the insert may be intermediate the TCE of the heat sink and the TCE, .alpha.3, of the material of the element. Preferably, the TCE of the insert approximately matches or is equal to the TCE of the material of the element. The element, the bottom portion of the heat-sink, the insert and the adhesive layers form a balanced "sandwich" structure. Such a structure will exhibit planar thermal expansion equivalent to the outer skins of the sandwich structure, e.g. of the element and the insert. Expansion of the structure normal to the element and the insert accommodates the balance of the absolute volumetric change of components of the sandwich structure not accounted for in the skins.

Title: Method and apparatus for load voltage compensation
Inventor: JOHNSON HAROLD LEE JR
IPC: H01F7/18
Filed: 1993-03-05
Granted: 2004-03-30
Abstract: An apparatus and method for load voltage compensation. This involves increasing the length of time voltage is applied to electrical components, e.g., solenoid valves, in direct proportion to the number of electrical components electrically activated to compensate for the voltage loss in the control wires leading to the electrical components. The area of compensated pulse is then equal to the area of uncompensated pulse in order to compensate for the voltage drop. The load is anticipated prior to voltage application by summing the number of electrical components and associated loads selected and applying voltage for a period of time directly proportional thereto.

Title: Method and apparatus for injection moulding rubber soles having at least two layers
Inventor: DREWINSKI HUBERT
IPC: B29C44/08
Filed: 1993-04-22
Granted: 2002-06-11
Abstract: Process for injection moulding rubber or rubber-mixture soles having at least two layers and connecting them to one another and if required to a shoe upper. First the rubber mixture for the bottom sole layer is injected into an enlarged mould cavity and the latter is made smaller to match the volume of the bottom sole layer; once the rubber mixture has partially solidified the upper delimitation means for the bottom sole layer is removed and is replaced by a last. The rubber mixture for the inner sole layer is infected into the thus created mould cavity. By displacing the bottom sole layer upwards, the mould cavity is made smaller to match the size of the inner sole layer; after partial solidification of the rubber mixture the lower delimitation means of the inner sole layer is lowered by a certain distance and the inner sole is allowed to expand in controlled manner with the mould cavity enlarged. The apparatus according to the invention (Fig. 6) provides an intermediate piece (1) which is arranged between lateral mould parts (16a) and the bottom die (2) and can traverse both horizontally and vertically.

Abstract: This invention provides a photoelectric transceiver (10) for detecting the presence and absence of objects (16) in a selected region (12). The transceiver (10) includes a light source (18), a light sensor (22), and electronic circuitry (13). The transceiver (10) generates a timing signal (MDCLK) that synchronizes its operation. In synchrony with the timing signal, the transceiver emits pulses of light (14) into the selected region (12) and senses light (24) coming from the selected region. When an object (16) is present in the selected region (12), the emitted light pulses (14) are reflected back to the transceiver (20). Based upon the light sensed, the transceiver generates an output (OUTOD) indicating whether or not an object is present. The transceiver includes three features that reduce the effect of interfering noise on the output (OUTOD). First, the output (OUTOD) is generated by a digital count hysteresis process to reduce the effect of random noise. Second, the transceiver timing signal (MDCLK) is modulated between two frequencies to reducethe effect of repetitive noise. Third, the transceiver timing signal (MDCLK) is interrupted when interfering noise is detected to further reduce the effect of noise. The transceiver includes a digital stability indicator (42) that indicates whether the transceiver operation is stable.
