Patent CA-2125971-A1 (CA)
Title: Treating building materials with a compound containing tin covalently bonded to a silylating group
Inventor: GEORGE BILLY L
IPC: A01N55/04
Filed: 1992-12-08
Abstract: Building materials such as concrete were previously coated with silicones or silicates for water repellency, but such treatments do not prevent algae or other growths. It has now been determined that building materials can be protected from the growth of algae by being treated with a compound containing tin covalently bonded to a silylating group such that cleavage of the covalent bonds due to hydrolysis or photolysis is minimized, thus making the treatment ecologically safe. One such compound is (n^_-Bu)3SnCH2CH2Si(OEt)3. The tin compound can either be incorporated into raw materials from which building materials are to be made, or it can be applied to the finished building materials. When the tin compounds is applied to a building material that is algae streaked, the streaking should disappear.

Title: Pilot stage for pressure control valves
Inventor: BOURKEL ARSENE
IPC: F16K17/10
Filed: 1994-07-27
Abstract: A pilot stage for pressure control valves comprises an axially displaceable valve piston (110) which bounds a valve chamber (141) axially on one side and includes a valve seat (140) for a closure cone (104) therein. Valve piston (110) has an actuating surface in a pressure chamber (164) that is substantially larger than the free cross-section of the valve seat (140). By pressurization of this pressure chamber (164), a large hydrostatic force is exerted on the valve piston (110) which opposes the closing force of the pressure-setting spring (106). A housing stop (130) fixes a first axial end position of the valve piston (110) in the direction of this hydrostatic force. The pilot control stage has improved properties both in manually adjustable pressure control valves and in proportional pressure control valves.

Patent CA-2133900-A1 (CA)
Inventor: DUNN ROBERT G
IPC: H04M1/00
Filed: 1994-10-07
Abstract: This invention is directed to a device for monitoring the integrity of telephone lines and for warning when the lines are inoperative. The device comprises a monitoring unit which continuously senses the voltage across the telephone lines and generates a control signal which assumes a first value when the lines are operational and a second value when the lines are inoperative. An alarm unit generates a warning signal of an audible frequency when the control signal assumes the second value, and is controlled with a switching unit. The switching unit maintains the alarm unit deactivated when the control signal has the first value and activates the alarm unit when the control signal has said second value.

Patent CA-2138385-A1 (CA)
Title: Method and device for motor-braking by means of a multi-cylinder internal combustion engine
Inventor: HAAKANSSON OLOF
IPC: F02B1/04
Filed: 1993-05-27
Abstract: A method for engine retardation with a multi-cylinder combustion engine, which for each cylinder with matching piston has an exhaust valve for control of the connection between a combustion chamber in the cylinder and an exhaust system. Opening of the exhaust valve for engine retardation is achieved by regulation of a clearance in the engine valve mechanism and thereby engaging one or more extra cam ridges on the engine camshaft, which continuously activates the valve mechanism in dependence of the momentary position of the engine crankshaft, using an actively adjustable, hydraulically operated clearance regulating device. For active control of the engine retardation said device is adjusted between different positions by means of a hydraulic fluid pressure lower than a maximum value controlled by a pressure relief valve. The angular position of the camshaft, at which the exhaust valves are being opened by said extra cam ridge or ridges is depending on the momentary clearance in the valve mechanism. The clearance is gradually brought to zero or close to zero while the pressure in the corresponding clearance regulating device is limited to a certain predetermined value. Independently of when in time during the cylinder work cycle the engine retardation is initiated or terminated, the risk of an opening against a, form a stress aspect, too high cylinder pressure is herby eliminated.

Patent CA-2147591-A1 (CA)
Title: Means and method for placing cable within coiled tubing
Inventor: BOYLE BRUCE W
IPC: H02G1/08
Filed: 1995-04-21
Abstract: A cable is injected into a length of coiled tubing disposed on a reel by an apparatus and method which includes attaching a small diameter pipe to the end of the coiled tubing, feeding the cable into the opposite end of the pipe through a seal and pumping a liquid into the annular space defined by the cable and the pipe at sufficient pressure and flow rate so that fluid drag on the cable overcomes the frictional force of the cable passing through the seal to inject the cable through the entire length of the coiled tubing. This method avoids the prior expensive practice of deploying coiled tubing in a straight line either horizontally or vertically in order to feed cable through the tubing.

Patent CA-2167236-A1 (CA)
Inventor: HERRICK DONNA W
IPC: H04Q3/62
Filed: 1996-01-15
Abstract: In a network of telecommunication switches, a first switch redirects a to-be-covered call to a remote call-covering endpoint served by a second switch,without losing control over the call. The first switch accompanies connection of the call to the second switch with signaling that identifies the call as a coverage call. The second switch responds to the signaling by determining the available status of the remote covering endpoint and signaling the status back to the first switch. If the remote covering endpoint is available, the second switch takes steps to connect the call to the endpoint. If the remote covering endpoint is not available, the first switch disconnects the call from the second switch and proceeds to cover the call to analternative covering endpoint. The net effect is that call coverage works -- from a user viewpoint -- identically across a network of switches as it does on a single switch.
