Patent CA-2113859-A1 (CA)
Inventor: BYAM MATTHEW D
IPC: B05B12/14
Filed: 1994-01-20
Abstract: A system for changing the coating material type supplied to a dispenser includes a manifold having a passageway through which the coating material flows during its selection.      A number of other passageways intersect the first passageway.      Supply valves mounted to the manifold control the flow of coating material through a selected one of the intersecting passageways into the first passageway. The mechanism fox actuating the flow control is controllable by an air signal positioning the control member and thereby controlling the supply of coating material to the first passageway. The manifold and valve bodies include second passageways that are coupled to a source of air under superatmospheric pressure. A valve controls the flow of air through the second passageway from the compressed air source to the interior of each valve body. By incorporating the second passageways into the manifold and valve bodies themselves, the distance the air signal must pass from the electrically operated valve to the control mechanism is minimized to advantage.

Filed: 1994-02-24
Abstract: ABSTRACT OF THE DISCLOSURE A curved tampon applicator is disclosed having an improved fingergrip for preventing rotation of the applicator during insertion of a catamenial tampon into a woman's vagina.  The applicator includes a tubular member having an arcuate shape with a centerline formed on an arc having a predetermined radius of curvature.  The tubular member has a stepped outer profile with an enlarged portion designed to house a tampon joined to a smaller fingergrip portion. The tubular member has a forward end through which the tampon is ejected and a rearward end through which a plunger is slidable.  The fingergrip portion has a passageway formed therethrough which is sized and configured to receive the plunger and an exterior periphery.  Formed on the exterior periphery of the fingergrip portion are first and second pairs of flat surfaces.  The first pair of the flat surfaces is aligned parallel to a plane coincident with a radius forming the arcuate centerline of the tubular member and the second pair of flat surfaces is aligned perpendicular to the first pair of flat surfaces.  The fingergrip portion also contains a plurality of spaced apart ribs, each of which completely surrounds the exterior periphery.  The ribs cooperate with the first and second pairs of flat surfaces to prevent rotation of the curved tampon applicator during insertion of a tampon into a woman's vagina.

Abstract: A difference vector determination element used in an apparatus for coding motion vector includes register memories (PMV) of which number is equal to sum of maximum transmission numbers N and M of forward predictive and backward predictive motion vectors. Motion vector counter counts the number of transmission of motion vectors to output a motion vector count signal. Register index designation signal generator designates indices of (1 ~ N (N+1) ~ (N +M)) in order of transmission of forward predictive or backward predictive motion vectors on the basis of attached information such as motion compensation mode, prediction type, and picture structure, etc. of motion vector, and the motion vector count signal from the motion vector counter to allow switch to perform switching operation, thus allowing register memories (PMV) and motion vectors to have one-to-one correspondence relationship. Difference circuit determines a difference between a motion vector inputted thereto and a value taken out from register memory (PMV) caused to correspond to the motion vector on the basis of motion compensation mode, etc.

IPC: H02M7/19
Filed: 1994-03-11
Abstract: A power conversion system for converting between AC and DC power has a pair of line commutated converters connected in series.  Each is connected to a corresponding transformer, one of which is YY connected and the other Y.DELTA. connected.  A pair of minimum voltage detectors generates minimum voltage signals, a first one of these signals being YY related and the second being Y.DELTA. related.  The system has a control circuit that generates two phase control signals for controlling the pair of converters, respectively.  When a fault occurs in AC or DC apparatus connected to this system, the control circuit generates the phase control signals on the basis of the first and second minimum voltage signals, respectively.  In this way, each of the converters is controlled by an independent signal, so that the power conversion of each is optimized.

Abstract: A bottom washcoat layer 2 and a top washcoat layer 3 including alumina (Al2O3) are sequentially laminated onto the surface of a monolith carrier 1.  Cerium, zirconium and palladium are carried in the bottom washcoat layer 2, and platinum, rhodium, barium and cerium are carried in the top washcoat layer 3.  The cerium content in the top washcoat layer 3 is set smaller than that in the bottom washcoat layer 2.  This causes the hydrocarbon conversion performance of rhodium and the nitrogen conversion performance of platinum in the top washcoat layer 3 to be balanced properly, while maintaining the hydrocarbon conversion performance of palladium in the bottom washcoat layer, thereby providing an improved exhaust gas purification performance as a whole.  In addition, platinum and palladium carried in separate washcoat layers make it possible to inhibit the formation of a platinum-palladium alloy under high temperature conditions to prevent a reduction in exhaust gas purification effect.          Further, the heat deterioration of cerium can be inhibited by zirconium, and the alumina surface area can be stabilized by barium, thereby providing an improved durability of the catalyst under high temperature conditions.

Title: Gas and Liquid Backflow-Preventing Valve Device for Drains
Inventor: KOR BOUKO J
IPC: E03F5/04
Filed: 1995-02-14
Abstract: ABSTRACT      A valve device for use with a drain provided with a pipe having an entrance for collecting liquid leading to a P-trap beneath the entrance.  The device comprising an open vessel, in use positioned at the entrance of the pipe, having walls and a floor defining an internal chamber, the floor having an opening for permitting liquid collected in the chamber to pass into the pipe.  The device is provided with a valve arranged to seat in the opening from below and is movable between a closed position sealing the opening against gas and liquid flow from the pipe to the chamber and an open position spaced from the opening beneath the floor.  A float is positioned in the internal chamber and a linkage transfers buoyancy force exerted on the float by liquid collected in the chamber to the valve to cause the valve to move from the closed position to the open position when the liquid exceeds a certain depth in the chamber.  The device provides an effective way of preventing backflow of gases and liquids from the drain, but overcomes problems caused by gas pressure build-up between the P-trap and the valve that would otherwise prevent the valve from opening properly.
