Title: Lamella of high stability for a vulcanization mold, vulcanization mold with such lamellas, vehicle tire with tire tread in which sipes are produced by such lamellas
Inventor: KLEINHOFF KLAUS
IPC: B60C11/13
Filed: 1999-03-23
Abstract: A lamella for use in a vehicle tire vulcanization mold has projections and depression, wherein the height of the projections and the depth of the depressions extend substantially parallel to a peripheral surface of the tire tread of the vehicle tire to be molded in the vulcanization mold. Each one of the projections has a highest point-shaped location or top. Each one of the depressions has a lowest point-shaped location or crater. The projections and depressions are distributed according to a substantially uniform areal division. The areal division is defined by dividing lines extending in a dividing plane preferably centrally positioned between a first plane defined by the tops and a second plane defined by the craters. The dividing lines are comprised of three sets wherein the dividing lines within each one of the sets extend parallel to one another and wherein the dividing lines of different ones of the sets intercept one another at an angle of substantially 60° so that a grid of triangles is formed. Instead of point-shaped highest or lowest locations, line-shaped highest and lowest locations can be provided.

Title: Preformed polymer coating process and product
Inventor: AVDALOVIC NEBOJSA
IPC: B01J20/286
Filed: 1997-12-10
Abstract: A method of coating a solid support (e.g. a capillary or chromatography packing) to alter the properties of the support surface for separating components in a fluid stream. The method comprises (a) covalently binding a coupling agent (including functional groups capable of forming free radical sites under hydrogen abstraction conditions) to the support surface in a uniform layer, and (b) thereafter, contacting the bound coupling agent with a solution of preformed polymer comprising totally saturated carbon chain backbones including leaving groups, under hydrogen abstraction conditions of elevated temperature in the presence of a free radical catalyst to remove leaving groups from the carbon chains to form free radical carbon binding sites which covalently bond to the coupling agent layer and to cross-link at least some of the preformed polymer through the free radical carbon binding sites to form a dimensional polymer network coating on said solid support surface. Alternatively, the coating is applied directly to an organic solid support without an intermediate coupling agent.

Title: Spray chamber with dryer
Inventor: LEGERE GUY
IPC: H01J49/10
Filed: 1997-12-22
Abstract: A spray chamber for producing a sample for an analyzer which may contain a plasma torch. In the chamber, a heated sheath gas is fed into the periphery of the spray surrounding the spray, adjacent the origin of the spray, thus reducing the size of droplets which are recirculated, thereby reducing agglomeration of the droplets and promoting rapid drying of the spray. Preferably all of the spray solvent is evaporated in a very short chamber, thus further reducing the amount of spray recirculated, and all of the combined flow of dried particulates from the spray, nebulizing gas and sheath gas is directed into the torch. In one embodiment, the central core of the combined flow is directed to the torch and the peripheral portion of the combined flow is ducted to waste. In another embodiment the aqueous spray solvent is fully evaporated before it leaves the spray chamber, and the combined flow is directed through a membrane dryer before reaching the torch, to remove most of the water vapor from the flow and thus to reduce water vapor loading on the torch.

Inventor: MYERS WESLEY DEAN
IPC: F16F1/06
Filed: 1999-07-14
Abstract: A noise-damped extension spring includes a resilient formed-in-place damper within the tubular spring body for damping vibrations of the spring. The damper is formed by placing a solidifiable composition such as heat-expandable foam-forming composition into the interior of the spring body, and causing the composition to solidify so as to form a resilient damper which generally conforms to the inner surface of the spring body. The method preferably includes heating the spring with the heat-expandable composition therein so as to both relieve residual stresses in the spring and cause expansion and solidification of the composition.

Title: Process for rapid activation of double metal cyanide catalysts
Inventor: ISAACS BRUCE H
IPC: B01J27/26
Filed: 1998-04-09
Abstract: A process for activating double metal cyanide catalysts is disclosed. A polyol starter or starter/catalyst mixture is heated under vacuum under conditions effective to achieve improved stripping compared with that which can be achieved through conventional vacuum stripping. Coupling vacuum stripping with inert gas sparging or stripping in the presence of an organic solvent gives a starter/catalyst mixture that activates rapidly in an epoxide polymerization process. Rapid activation makes process start-ups reliable and reduces cycle time. The process gives polyols with lower viscosity, lower polydispersity, and lower unsaturation for better polyurethanes.

Patent CA-2289059-A1 (CA)
Inventor: CHAPMAN WILLIAM A
IPC: E04H12/22
Filed: 1998-05-08
Abstract: A coupling device (A), wherein separate individual elements (142) and a sliding interlocked connection mechanism (170a, 166) for connecting individual tenons (148) to a wall portion of a link module provide several advantages.  The tenon members (148) are individually adjustable on the wall portion to give various intermeshing arrangements. Therefore, instead of manufacturing several individual different link modules to obtain a variety of different intermeshing arrangements, one needs only to manufacture a standard wall portion (142) and a standard type of tenon means (148), so that any intermesh can be provided by simply assembling tenon means and wall portions. The tenon members may be used on either wall end portion by simply detaching from one wall end, inverting, and reattaching to the other wall end.

Title: Blow moulding method and device
Inventor: GALLAY JEAN
IPC: B29C49/78
Filed: 1998-06-02
Abstract: The invention concerns a device for implementing a blow moulding method providing a better distribution of operating power, comprising several modules (11, 12, 13) connected by a continuously driven conveyor belt (14). Each module comprises a furnace (17) heating preforms, a transfer wheel (18), means (19) transferring preforms from the conveyor belt onto the transfer wheel, a press (20) moulding objects from the preforms and a member unloading (21) the moulded objects. Preforms are brought in the proximity of all the modules by means of the conveyor belt, then two preforms are brought on each transfer wheel module. In order to stagger the high power-consuming steps, such as opening the press and blowing the objects from the heated preforms, the method consists in modifying the travel distance between the preform loading point and the transfer means and/or between the transfer means and the press opening point or both distances from one of the modules to the other simultaneously.

Abstract: The present invention involves the passing of clock information from a point where a tributary payload is mapped into a carrier to a point where a tributary payload is de-mapped from the carrier. A synchronization signal is generated at the mapping end.  Rather than sending clock phase information implicitly by means of the data, as is normally the case, a value of the synchronization signal at a given time, is sent explicitly, independent from the payload data.
