Abstract: ABSTRACT OF THE DISCLOSURE           An actuator   for a valve   disposed in a gas pipe line  is  driven directly by the gas pressure in the pipe line, which is tapped off and supplied to the appropriate end of the actuator cylinder via an electromagnetic spool valve.          A hydraulic transfer circuit couples the chambers on the piston rod sides of the actuator cylinder, and includes flow con-trol valves   for regulating the actuator speed and an oil expansion tank.  The latter may be sealed and a positive pressure established therein to facilitate the oil transfer.          A hand  pump  may  also be provided to implement the oil transfer and drive the actuator piston from the piston rod side if the gas pressure is too low to power the actuator.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a new and useful mounting device for electrical connectors and associated wiring.  In various prior termination systems, incoming trunks were extended, usually under-ground, from a central office to a distribution frame, usually located in a basement or other utility area of an office building.           With personnel changes in customer's facility, and with changes of customers, maintenance and modification of the connection system may become a problem.  The present invention overcomes these problems by providing a device which couples two types of connectors together in an integral unit, thereby aiding in quick connect and disconnect of the lines.  According to the invention, there is provided a mounting device for electrical connectors molded in one piece to provide functions of supporting longitudinally elongated electrical connectors of a first type, for supporting electrical connector units of a second type having contact members arranged for gang connection, and for housing electrical wiring therebetween.  The one-piece device includes a raised rectangular mounting platform.  The mounting platform includes integrally formed upper and lower sections.  The upper section includes means for supporting the connectors of the first type and means for defining a passageway at the rear of the supported first type con-nectors.  The lower transverse side is open to permit the wiring to extend toward the lower section.  A key hole aperture facilitates engagement with a mounting bolt on the building wall.  The lower section includes stepped connector mounting panels having inclined surfaces.

Abstract: METHOD OF FORMING A SILICON NITRIDE ARTICLE                   ABSTRACT OF THE DISCLOSURE           A method for forming a silicon nitride article is set forth.  An article having at least some silicon par-ticles therein is formed in a manner which provides a degree of porosity for the article.  The silicon particles of the article are reactable with nitrogen to form silicon nitride.          The article is heated to a temperature below a reaction temperature at which nitrogen gas reacts with the silicon particles.  The article is surrounded with an atmosphere containing at least some nitrogen gas.  A reaction zone is established on at least a portion of the surface area of the article.  The reaction zone has a temperature above the reaction temperature whereby the silicon particles in the reaction zone are reacted with the nitrogen gas to form silicon nitride.  The reaction zone is moved from the surface of the article into the interior of the article whereby the article is progressively nitrided inwardly into its bulk from the surface thereof.

Abstract: Abstract of the Disclosure A gas spring for movable members such as vehicle deck lids in which a piston assembly carried on the end of a rod slides back and forth in a cylinder to expand and contract the spring. The cylinder is sealed at the head end and also around the rod and is filled with a combination of oil and a gas under pressure.  The piston assembly is such that the passage of oil and gas from one side to the other is restricted as the spring is expanded by extending the rod and this produces a dampening action but the restriction is eliminated when the spring is contracted so that there is virtually no dampening effect.  The sealing assembly around the rod includes sealing means, an oil reservoir disposed inwardly of the sealing means and capillary passages communicating with the reservoir.  Capillary action maintains a body of oil between the sealing means and the gas in the cylinder irrespective of the angular attitude of the spring.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a catalytic warmer or heater which may be made in different sizes and shapes.  A chimney section top has an opening through which a heatable material container is insertable, and which rests on an X-frame supported on punched-in tongues providing draft apertures for the chimney, while a lower spaced series of punched-in tongues rest on a catalyst containing cage which, in turn, rests on a flange of fuel cartridge section below having a wick extending up from the cartridge to be lighted temporarily to initiate the catalytic combustion process.  The supporting X-frame has a depending cylinder providing a snuffer to snuff out the wick and permit the catalytic combustion to continue.  The catalytic combustion is stopped when desired by merely turning the entire heater ox warmer upside down and then removing the fuel cartridge containing section, now on top, from the chimney section, now on bottom, the catalyst cage remaining with the chimney section and thus separated from the cartridge fuel section.

The system includes a plurality of inflatable, collapsible, submersible buoys which may be remotely controlled by air or other inflating mediums.  As each of the buoys, and thus the load connected thereto, is lowered or raised in a body of water the pressure inside the buoys is controlled by a valve which is responsive to the hydro-static pressure in the body of water or the volume of the buoy to maintain a relatively small pressure differential between the pressure inside the buoy and the hydro-static pressure at all depths of submersion whether the amount of buoyancy provided by the buoys is to be positive, negative, or neutral.  Also disclosed are a plurality of systems utilizing the submersible buoys of this invention for laying pipe line-and other objects on or near the sea bottom.

Abstract: ABSTRACT OF THE DISCLOSURE A relatively low temperature process for separating and recovering bitumen from natural tar sands wherein granular sulfur and water are mixed with the tar sand, in the presence of air, to form a sulfur-bitumen agglomerate whichfloats on the water, with relatively bitumen-free sand sinking to the bottom. The agglomerate may be skimmed off the surface of the water and bitumen recovered therefrom by heating the agglomerate to melt the sulfur and then separating the molten sulfur from the hot bitumen.  It has unexpectedly been discovered that a yield of over 80% of bitumen can be recovered from the tar sands by the use of sulfur in the process, compared to only about 20% if sulfur is not present.
