Title: Improvements relating to fasteners
Inventor: PARKER GARY
IPC: E03C1/04
Filed: 2000-03-15
Granted: 2009-03-10
Abstract: A fastener for receiving a sink unit in a worktop has a plastics clip (1) for attaching to a tab or rail (4) and a hinged clamping member (11) which is tightened up against the underside of the worktop by a screw (16). The screw can be pressed through a bore (19) in the hinge pin and self-tap into a non-threaded passage (8) in the clip (1) when the clamping member (11) is hinged to engage under the worktop. The bore (19) through the hinge pin (9) has small flexible tags (20) projecting into it past which the screw thread can snap, but which retain the screw (16) when that is not engaged with the clip (1). The hinge pin (9) and the clip have mutually engageable detents (22, 23, 24) which locate the pin (9), and thus the clamping member (11), in either the operative position, for engaging the worktop, or the non-operative position with the clamping member swung back free of the worktop.

Abstract: A thermal compensating apparatus and method for maintaining a relatively constant fluid pressure within a subterranean well tool of the type that is responsive to a source of actuation fluid for manipulating said tool at a location in a well to at least one of sealing and anchoring positions. A body includes a fluid chamber within the body for housing a substantially incompressible fluid for manipulating said tool to at least one of the positions. The fluid chamber is expandable and contractible, for example, through movement of a piston, in response to manipulation of the tool and thereafter in response to thermal variations of the fluid in the fluid chamber. An energy storage and release mechanism, for example, a compression spring, is responsive to pressure changes in the fluid chamber for expanding or contracting the fluid chamber in response to pressure variations in the fluid for maintaining the fluid at a relatively constant pressure.

Abstract: In a belt for a continuously variable transmission, a first clearance CL NH is defined between a projection and a recess formed on front and rear surfaces of a metal element, and a second clearance C Ly is defined between an upper surface of a metal ring assembly and a lower ear surface of the metal element. The setting of a relation, CLY > CL NH ensures that when the metal element has been pitched, the projection and the recess can be first brought into contact with each other, thereby preventing a reduction in durability which may otherwise occur by the lower ear surface coming into contact with the upper surface of the metal ring assembly. If the thickness of the metal ring assembly is represented by T L, and the vertical opening of the ring slot is represented by D, when the value of D/T L exceeds 11/8, the power transmitting efficiency is reduced. Therefore, the reduction in power transmitting efficiency can be prevented by setting D/T L at a smaller value than 11/8. Thus, it is possible to ensure a power transmitting efficiency, while preventing a reduction in durability of the metal ring assembly due to the pitching of the metal element.

Title: Method and apparatus for supervising a potentially gated signal in a wireless communication system
Inventor: JOU YU-CHEUN
IPC: H04W52/28
Filed: 2000-06-22
Granted: 2011-12-06
Abstract: This is a method and apparatus for supervising a potentially gated channel in a wireless communication system. The mobile station (4) maintains a counter of consecutive bad frames, COUNT1 (224), and a counter of consecutive good frames, COUNT2 (226). COUNT1 (224) and COUNT2 (226) are set to zero at the beginning of a call. For each frame received, the mobile station (4) determines if it is a good, bad, or an empty frame. If the received frame is good, COUNT1 (224) is reset to zero and COUNT2 (226) is incremented by 1. If the received frame is bad, COUNT1 (224) is incremented by one and COUNT2 (226) is reset to zero. If the received frame is empty, COUNT1 (224) and COUNT2 (226) are unchanged. If COUNT1 (224) reaches a threshold value, TH1, the mobile station (4) shall disable its transmitter. Thereafter, if COUNT2 (226) reaches a threshold value, TH2, the mobile station (4) shall re-enable its transmitter.

Abstract: L'invention concerne un système d'administration gastro-intestinal à deux impulsions, comprenant un agent spécifique en combinaison avec un matériau noyau gonflable, le noyau étant entouré d'une couche intérieure d'un matériau de revêtement hydro-insoluble ou relativement hydro-insoluble, contenant une substance hydro-insoluble particulaire. En outre, la couche intérieure est enveloppée d'une couche extérieure contenant des quantités supplémentaires dudit agent. Lorsque le dispositif d'administration pénètre dans le tractus gastro-intestinal, la couche extérieure libère l'agent spécifique qu'elle contient et se désagrège, exposant ainsi la couche intérieure. La substance particulaire de la couche intérieure s'imprègne de liquide, ce qui constitue des canaux reliant le noyau contenant le médicament et la partie extérieure du dispositif d'administration. Grâce à ces canaux, le liquide peut pénétrer dans le noyau, qui commence à gonfler jusqu'à la rupture de la couche intérieure. Après destruction de l'intégrité de la couche intérieure, le noyau se désagrège à son tour, libérant immédiatement la totalité ou une partie du médicament en un site spécifique. En contrôlant les paramètres du dispositif, tels que le matériau noyau, l'excipient du revêtement et la substance particulaire, on peut maîtriser avec précision le lieu de libération des deux impulsions du médicament. L'invention concerne également un procédé d'utilisation du dispositif dans le traitement de maladies par la libération de médicaments dans le tractus gastro-intestinal en fonction de l'emplacement et du temps.

Title: Measurement of pipe joint misalignment at weld interface
Inventor: CARTER COLIN LESLY
IPC: B23K31/02
Filed: 2001-03-19
Granted: 2006-12-12
Abstract: A method of monitoring the alignment of pipes to be welded end to end involves supporting a reference bar extending generally parallel to, and external of, the pipes so as to span a weld position of which the ends of two pipes are to be welded, performing measurements of perpendicular distance between the bar and each pipe at two predetermined distances from the end of each pipe, determining the thickness of the walls of the pipes, determining the slope of the exterior of each pipe with respect to the reference bar, calculating from the slopes the difference between the distances from the bar to the outer surface of each of the two pipes to the weld position, so as to provide a measure of the misalignment of the outer surface of the pipes at the weld position, differencing the wall thicknesses of the pipes to provide a wall thickness difference, and subtracting the wall thickness difference from the misalignment of the external walls of the pipe to determine the misalignment of the inner surfaces of the pipes at the weld position. It is preferred to measure pipe thicknesses at multiple distances from the end of each pipe and average the results to obtain average thicknesses for the two pipes. The misalignment measurements will usually be repeated at successive points around the periphery of the pipes.
