Title: Uv curable coatings
Inventor: JIN PEIWEN
IPC: C09D4/00
Filed: 1996-08-21
Abstract: The present invention relates to oligomers or prepolymers which are formed by reacting an isocyanate, a lactone adduct and a  hydroxyalkyl acrylate or methacrylate.  These oligomers can be used to make UV curable coatings by adding acrylate monomers, photoinitiators and wetting agents.  Transparent, abrasion resistant surfaces result from the cure by ultraviolet light of these coatings on substrates such as PVC based substrates.  By adjusting the ratio of hydroxyalkyl acrylate or methacrylate and the lactone adduct component in the oligomer, coatings with both high tensile strength and elongation can be obtained.

Title: Oil level control apparatus
Inventor: WALLER CLIVE GREGORY
IPC: F01M11/12
Filed: 1995-06-16
Abstract: An apparatus (38) is disclosed for controlling the level of oil in one or more compressors (10) of a refrigeration system. The compressors (10) are supplied with oil from a reservoir (28) which is in fluid communication via a common conduit (32) and second conduit (98) with the oil sump (not shown) of each compressor (10). The apparatus (38) includes a housing composed of a main body portion and a spacer block. The body portion is provided with a chamber which houses a float. The chamber is in fluid communication with the oil sump of its respective compressor (10). As the oil level within the compressor (10) varies, the angle of pivot of float also varies. This variation is sensed by a sensor which produces a signal indicative of the level of the oil. When the signal is indicative that the level of oil within the compressor is below a first predetermined minimum level, solenoid valve (78) is opened and solenoid valve (82) closed. This allows oil from the reservoir (24) to flow via conduits (32 and 98) into the compressor. In another embodiment, if the signal is indicative that the oil level within the compressor is higher than a predetermined maximum level, solenoid valve (78) is caused to close and solenoid valve (82) caused to open resulting in oil being dumped from the compressor back to the oil reservoir (28) via conduits (98 and 32).

Title: Overload prevention in a telecommunications network node
Inventor: GINZBOORG PHILIP
IPC: H04Q3/66
Filed: 1995-11-10
Abstract: The invention relates to a method of preventing an overload in a telecommunications network node. The network comprises at least one service node (CN; SCP) and at least one other node (PN; SSP) from which the service node receives service requests. According to the method, the service node transmits restriction requests (CG) to a node connected thereto, so that said node would restrict the number of service requests it transmits towards the service node. The restriction request comprises a group of parameters that indicates how the node should perform restriction. A restriction request is transmitted at least whenever said group of parameters changes. In order to provide a simple and reliable method, (a) the service node adds to the restriction request it transmits information identifying the aforementioned group of parameters on the basis of which the node should perform restriction, (b) the node copies said information into its memory and transmits the data identifying the groups of parameters it uses back to the service node, and (c) the service node compares said data with the data it has transmitted, and decides on the basis of the comparison whether a restriction request is transmitted to the node which transmitted the data.

Inventor: EATON TIMOTHY C
IPC: F23D14/72
Filed: 1997-06-10
Abstract: Purging of a gas supply line is effected using a serviceman's purging tool having a hose for attachment to the supply line with an opposite end of the hose attached to a burner nozzle carried on a support frame. The burner nozzle is arranged to generate a stream of the gases exiting from the pipe to be purged. The frame carries a receptacle for a propane torch and angles the burner of the torch so as to be directed across the stream of gas from the supply pipe. The burner from the torch thus provides combustion of the purged non-ignitable products from the supply pipe until the ignitable gas reaches the nozzle whereupon the ignitable gas is ignited indicating that the pipe is purged. The receptacle comprises a cylindrical sleeve for receiving the tank of the propane torch and a bracket for guiding the nozzle of the torch across the stream.

Title: Mold core-pin deflection transducer
Inventor: WURST RICHARD
IPC: B29C33/76
Filed: 1995-12-11
Abstract: A transducer (10) for measuring the amount of lateral deflection taking place at the tip (22) of a core-pin inside a mold or die cavity (16). Non-uniform cavity pressure and cooling patterns make core-pins prone to deflection resulting in out-of-tolerance thin and thick wall sections of the finished part. The transducer provides a means of determining deflection as it occurs during the molding process for statistical quality control. Real time measurement of the core deflection allows discrimination of unacceptable and reject parts for an automatic part sorting process. In the preferred embodiment a plurality of strain gauges (24) mounted on the core-pin outside of the mold cavity provide real time electric signals of lateral deflection that can be used to automatically segregate reject parts and provide for statistical process control.
Patent CA-2209874-A1 (CA)
Inventor: BRADDICK BRITT O
IPC: E21B29/06
Filed: 1997-07-09
Abstract: A thru tubing whipstock assembly 10 may be set within a casing string CS after passing through the lower end of a smaller diameter tubing string TS. Once set within the casing string CS, the whipstock face 18 on whipstock body 12 may divert a rotatable bit B for cutting a window in the casing string CS. The whipstock assembly 10 includes an anchor A below the whipstock body 12 for securing the set whipstock assembly within the casing string. A hinge assembly 14 below the whipstock body 12 may be pivoted from a run-in position for passing through the tubing string to a set position for positioning the whipstock face 18 for engagement with the bit B. A wedge assembly 38 is provided at the upper end of whipstock body 12 and is also movable from a run-in position to a set position. The wedge assembly includes an outer wedge member 102 for engaging an interior wall of the casing string at a position circumferentially opposite the location where the window is to be cut, and an inner wedge member 104 slidably moveable with respect to both the outer wedge member 102 and the whipstock body 12. An elongate rod 52 is positioned within a bore 54 extending through the outer wedge member, the inner wedge member, and an upper portion of the whipstock body 12 when in the run-in position. The rod 52 retains the wedge assembly in the run-in position, and is removed to allow the outer wedge member 102 and inner wedge member 104 to move to the set position. A rod extension 92 extends through a passageway 94 in the whipstock body 12 so that a lower end of the rod extension 92 fits within a socket 160 within a hinge arm 166 to retain the hinge assembly in the run-in position. Once the rod 52 is moved upward, the biasing force of a spring 150 moves the rod extension 92 out of the socket 160, thereby allowing the hinge assembly to pivot to its set position. The whipstock assembly is also retrievable through the tubing string.
