Patent CA-2043772-C (CA)
Title: Magnetic reproducing apparatus and magnetic recording/reproducing apparatus
Inventor: IWAMURA SOICHI
IPC: H04N5/92
Filed: 1991-06-03
Granted: 1995-05-23
Abstract: In recording, a carrier is FM-modulated with a video signal to produce a FM carrier.  The phase of the FM carrier corresponding to a tip portion of a horizontal synchronizing pulse in the video signal (sync-tip carrier), is reset so that the phase is fixed at a reference phase at a leading edge of the horizontal synchronizing pulse during every period of the horizontal synchronizing pulse width.          The sync-tip carrier with its phase fixed is recorded in a magnetic recording medium.  In reproducing, the FM carrier picked up by the magnetic recording medium, with its frequency doubled by a doubler, is demodulated by a pulse count-type FM demodulator with a doubler function.  Then, a part of the FM carrier spectrum leaks into the FM demodulated video signal band, but the FM carrier is always in phase with the horizontal synchronizing pulse in the video signal, so that beat stripes or moiré do not appear on the reproduced picture, and the interference due to the leakage appears as reproduced picture distortion in correlation with the video signal.  Since the reproduced picture distortion is not likely to be detected by a human being as compared to asynchronously drifting beat stripes, the output of the doubler does not have to be passed through a high-pass filter to cut off a part of the lower sideband of the FM carrier.          The reference burst signal necessary to a time base corrector is extracted from the reproduced sync-tip carrier.

Title: Method of prevention of adhesion of hot-mix asphalt to containers and equipment
Inventor: BALLENGER WILLIAM THOMAS JR
IPC: B05D5/08
Filed: 1992-02-11
Granted: 2000-01-18
Abstract: An improved method of prevention of adhesion of hot-mix asphalt to dump trucks and other containers or equipment comprises preparing an aqueous dispersion of a vegetable oil and applying the dispersion to the surface of the container before loading the hot-mix asphalt therein. Vegetable oils which are useful as release agents in aqueous dispersion include cottonseed oil, soya oil, rate (canola) oil, peanut oil, corn oil, sunflower oil, palm oil, coconut oil and palm kernel oil. The oil is emulsified in water, using a suitable emulsifier, preferably a sorbitol base emulsifier, in the amount of 1 - 5 oz. per gallon of water. The oil and emulsifier are preferably premixed and supplied as a self-emulsifiable composition. The resulting emulsion is applied in an amount to provide a thin coating on the wall of the container or equipment. The emulsion is applied in the amount of 3 - 4 qts. to coat a dump truck or 4 - 6 qts. to coat a trailer. The hot-mix asphalt is easily removed from the container, i.e. truck or trailer, or other equipment without sticking and the release agent has been found to be completely biodegradable.

Granted: 2004-01-13
Abstract: Tri- and tetra-substituted guanidines which exhibit a high binding affinity to phencyclidine (PCP) receptors and, more preferably, low affinity to the brain sigma receptors. These guanidine derivatives act as non-competitive inhibitors of glutamate induced responses of the NMDA receptor by acting as blockers for the ion channel of the NMDA receptor-ion channel complex. These compounds thus exert neuroprotective activity and are useful in the therapeutic treatment of neuronal loss in , hy-poglycemia, brain or spinal cord ischemia, and brain or spinal card trauma as well as being; useful for the treatment of epilepsy, Alzheimer's disease, Amyotrophic Lateral Sclerosis, Parkinson's disease, Huntington's disease, Down's Syndrome, Korsakoff's disease and other neurodegenerative disorders.

Title: Improved error reporting for translated code execution
Inventor: ROBINSON SCOTT G
IPC: G06F9/45
Filed: 1992-03-03
Granted: 1996-12-31
Abstract: In a situation where a first computer program has been translated to obtain a second computer program, an error occurring during execution of the second computer program is reported in the context of the first program. This is done by aborting execu-tion of the second computer program when the error occurs; determining a first address which is the address of the instruction in the second computer program that caused the error; determining from the first address a second address of an instruction in the first computer program from which the instruction in the second computer program was translated; and reporting that the error occurred, and using the second address to indicate that the error is associated with the instruction in the first computer program. Preferably the second address is used to reference traceback and symbolic name information generated when the first computer program is compiled from source code. The traceback information provides the line number of the source code from which the instruction in the first computer program was compiled, and the symbolic name information provides the name of a routine con-taining the instruction in the first program or a variable used by the instruction.

Abstract: process for removing volatile constituents from a polymer dispersion or solution by stripping with a carrier gas is disclosed.  The carrier gas being, in the case of a polymer solution, the vapor of the solvent used for the polymer solution as an inert gas saturated with said vapor.  In the case of a polymer dispersion, the vapor of the dispersing medium used for the polymer dispersion or an inert gas saturated with said vapor.          In both processes certain amount of the carrier gas is passed through the polymer dispersion or solution, the volatile constituents taken up the carrier gas on passage through the polymer dispersion or solution are then removed from the carrier gas in such a manner that the energy content of the carrier gas remains essentially unchanged.  The carrier gas thus obtained is then reused for further removal of volatile constituents from the same polymer dispersion or solution by stripping.

Granted: 1996-09-17
Abstract: A novel micro-emulsion is described which is useful as a hydrogenation catalyst. The highly dispersed hydrogenation catalyst is prepared by forming an aqueous solution of a salt of a transition metal and a surfactant, adding this solution to heated petroleum pitch or a mixture thereof with a petroleum distillate, such as heavy gas oil, and mixing vigorously until a stable water-in-oil micro-emulsion is formed having an average diameter of less than about 1500.ANG., which upon exposure to severe reducing conditions produces catalyst particles having an average size of less than about 500.ANG.. The micro-emulsion thus formed is highly stable and has a long shelf-life and the catalyst particles formed under hydrogenation conditions are much smaller than previously reported.

Abstract: A dispenser (10) which can deliver precise small amounts of a liquid is disclosed. The dispenser is particularly suited to applying reagents in a bio-logical test such as an immunoassay. It includes a reservoir chamber (12) linked to a dispense chamber (11) via a check valve, the two chambers prefer-ably being in the form of syringes (110, 120).  An outlet line leading from the dispense chamber (11) to a nozzle (14) includes a delay check valve (prefer-ably a ball inside a cylindrical chamber (135)) which allows continuous out-ward flow, but shuts off flow in the reverse direction after allowing a prede-termined volume to pass. The process of refilling the dispense chamber (11) from the reservoir chamber (12) creates reverse flow in the nozzle (14) and causes a hanging drop of liquid at the tip of the nozzle (14) to be withdrawn.

Abstract: This  invention  relates  to  electrical  connectors, specifically to an electrical connector that is easy to insert into a hole or knock-out of an electrical junction box.  Design of the connector provides for positive fixture of the connector in the box once non-metallic sheathed cable, either  oval  or circular  in  cross-directional  shape,  is inserted through the connector, thus preventing the cable from being withdrawn.  The C-shaped one piece connector of this disclosure contains an integral hinge, a cutout area, and a necked down area on the top flange to provide for easy flexing about the central insertion axis and therefore easy insertion into an electrical junction box.  The jaws of the electrical connector are designed such that a positive bite or grip is applied to an oval or circular non-metallic sheathed cable as tension is applied on said cable to attempt to remove it from said electrical enclosure.
