Patent CA-2130797-A1 (CA)
Title: 2,3,4,5-tetrahydro-1h-3-benzazepines having anti-psychotic activity, and synthesis of .alpha.-substituted-arylacetamides
Inventor: BERGER JOEL G
IPC: C07B61/00
Filed: 1993-02-23
Abstract: A novel process for the preparation of .alpha.-substituted arylacetamides wherein the substituent is an aromatic group or a 1-alkenyl or 1-cycloalkenyl group and wherein the nitrogen atom carries no hydrogen atoms comprises the reaction of an arylacetamide having one or two hydrogen atoms on the .alpha.-carbon atom, wherein the nitrogen atom carries no hydrogen atoms, with a strong base in an inert aprotic organic solvent, followed by reaction with a zerovalent transition metal catalyst and then with a compound of the formula R4-X, wherein R4 is selected from aromatic groups, 1-alkenyl groups and 1-cycloalkenyl groups and X is a particular leaving group, especially a triflate group. The .alpha.-substituted arylacetamides are useful as intermediates in the preparation (by reduction) of .alpha.-substituted arylethylamines, e.g., 1-substituted-2,3,4,5-tetrahydro-1H-3-benzazepines, having pharmacological activity. Certain benzazepines wherein the 1-substituent R4 is 1-(1-cycloalkenyl) are novel.

IPC: H02G5/06
Filed: 1995-03-16
Abstract: An electrical power transmission line  is particularly adapted for the transmission of electrical power from relatively small and remotely located hydroelectric  sites and  over rugged terrain.  The line comprises a  plurality of conducting  elements, preferably assembled from copper tubing or pipe with loosely fitting slip joints to allow for thermal expansion, with concentric outer insulating  elements of polyvinyl  chloride pipe or tubing,  which insulating  elements  are  hermetically sealed   together.   The conducting element is spaced apart from the inner walls of the insulating   element by plural spacers  installed  therebetween, to provide an air gap between conductor and insulator. The use of a combination of standard, off the shelf components provides a relatively economical construction, with the relatively light weight of  the components providing for shipment by air to remote sites and the standardization of the  components providing for ease of assembly in remote areas by relatively unskilled labor using minimal hand tools and equipment, without need for the construction of a right of way for a conventional electrical power line.   A method of constructing such a line is also disclosed.

Patent CA-2149003-A1 (CA)
Title: Process of producing methanol
Inventor: KOENIG PETER
IPC: C07C29/151
Filed: 1995-05-09
Abstract: From a synthesis gas which contains hydrogen and carbon oxides, methanol is produced on copper-containing catalysts under pressures in the range from 20 to 120 bars and at temperatures in the range from 200 to 350°C. The synthesis gas is passed through a first synthesis reactor, which consists of a shaft reactor and contains a fixed bed of a copper-containing catalyst. The reaction in the shaft reactor is carried out adiabatically and without a recycling of synthesis gas. Together with recycle gas, the gas mixture which has not been reacted in the first synthesis reactor is passed through a second synthesis reactor, which contains a copper-containing catalyst, which is disposed in tubes and is indirectly cooled through boiling water. 10 to 30% of the carbon oxides of the synthesis gas are reacted in the shaft reactor to form methanol.
Patent CA-2149101-A1 (CA)
Title: Long life battery operated acoustic underwater buoy release system
Inventor: RAU BRIEN G
IPC: B63B22/06
Filed: 1995-05-10
Abstract: A battery operated system responds to coded acoustic signals for releasing a buoyed housing from an underwater anchor to carry a retrieval line attached to a retrievable underwater object to the water surface. A novel tethering mechanism is provided for attaching the housing to a line 38 tethered to the anchor and for releasing it in response to the coded acoustic signals. The tethering mechanism operates in two diverse modes. Thus, the housing is released from its tether line thermally by battery power which melts an expandable wax body in a thermal actuator 36 to move an actuating member 37 through a line release stroke. The tether line is attached by a manually actuated latching mechanism 45, 47 provided for retethering the housing by resetting the latching mechanism without draining battery. The exit angle of the line leaving a lower latching compartment outwardly is restricted to prevent substantial changes in line orientation thereby to reduce fouling of the tether line in response to underwater currents. The tether line attaching mechanism comprises in separate embodiments either a set of line clamping cams or a latched set of levers, either of which releases the line in response to thermal movement of an actuating member.

Abstract: Laminé décoratif à activation thermique formé à partir d'un premier élément fait d'une première feuille transparente au rayonnement générateur d'images et présentant au moins une zone superficielle ou une couche d'un polymère thermosensible activé lorsque le laminé est soumis à un rayonnement bref et intense. Ledit premier élément porte une couche d'une substance poreuse ou particulaire de formation d'images présentant en plus de sa cohésion une adhérence vis-à-vis de la couche de polymère thermosensible et, à l'opposé de la couche de substance poreuse ou particulaire de formation d'images, une première couche d'adhésif, et un second élément fait d'une seconde feuille portant une seconde couche d'adhésif. La seconde couche d'adhésif est constituée d'un polymère durcissable à liant organique macromoléculaire présentant des groupes acides et d'un monomère photopolymérisable. Le premier et le deuxième élément sont laminés ensemble et avec la première et la seconde couche d'adhésif, en contact l'une avec l'autre, de façon à former un seul laminé dans lequel l'adhésif durcissable reste à l'état non durci et sert à réduire la tendance du laminé à se délaminer sous les contraintes. Il ne faut qu'un délai très court, de l'ordre de 10 à 90 s, entre le laminage et le durcissement de l'adhésif durcissable pour obtenir après durcissement une liaison tenace entre les deux éléments.

Patent CA-2174088-A1 (CA)
Title: Drum brake
Inventor: TANAKA SHINICHI
IPC: F16D65/22
Filed: 1995-09-01
Abstract: Brake noise (the unpleasant "screeching" noise) produced when a motor vehicle brakes is effectively reduced. A rod is provided upright on the inside of the rim to which the brake lining is fitted, and a weight is fitted to this rod by way of an elastic body. By fitting a weight to the brake shoe by way of an intermediary elastic body, the weight will vibrate when it is subject to the vibration of the brake shoe. At low frequencies the vibration of the weight will be in phase with the vibration of the brake shoe, but as the vibration frequency of the brake shoe increases, the vibration of the weight will shift out of phase with the vibration of the brake shoe. In the vicinity of and above a certain frequency, this phase difference will become nearly 180 degrees. By matching this frequency to the brake noise frequency, the vibration of the brake shoe can be suppressed by the vibration of the weight. Simply by adding inexpensive parts, brake noise of a large-sized vehicle with large brake shoes can be reduced sufficiently for practical purposes. Moreover, the essential performance can be maintained when the brake lining is replaced.

The panels and column connectors are fused together by passing electrical current through conductors (246) at interconnection points, raising the temperature to melt the material.  Rebar (276, 278) and concrete are placed in the shell.  A bridge is made by forms (310) assembled at a terminal location, elevated, suspended upon cables (374) passing between two locations, and pulled to sequentially engage previously positioned forms until the forms extend between the two locations.  The forms are filled with rebar (372) and concrete and provide an exterior finished surface.
