Abstract: ABSTRACT OF THE DISCLOSURE A light dimmer product is provided having simpler construc-tion and simpler assembly than prior art dimmers.  Simplicity of construction is achieved by providing a printed circuit board and moutning all electrical leads from components to the board to permit a single soldering operation to solder all leads simultaneously.      Simplicity of assembly is achieved by mounting portions other than current carrying portions to the mounting bracket of the dimmer product as a sub-assembly to be assembled to the housing.  When assembled, the bracket support components by portions other than current carrying portions and the current carrying portion of these same components support the printed circuit board.  The printed circuit board supports other components by their current carrying portions.

Abstract: APPARATUS FOR APPLYING LIQUID OCATING ONTO THE EXTERNAL SURFACE OF THE WALL OF A MAIN PIPELINE             A B S T R A C T      The apparatus includes a drive carriage adapted to be mounted on the pipeline and carrying a container for the supply of the liquid coating, communicating with a hollow distributor, as well as a trough and a receptacle, suspended from the distributor on rods and adapted to be positioned un-der the pipeline to receive the superfluous liquid coating overflowing the external surface of the wall of the piepline. The carriage further supports a s???? pump for supplying the liquid coating from the receptacle into the distributor.      The hollow distributor has two branch pipes communicating therewith through the outlets made in the leading end wall of the distributor, in the direction of the progress of the coat-ing process, the branch pipes having their outlet ends facing the side portions of the pipeline wall.  Furthermore, the inlet connecting the distributor with the container has mounted the-rein a maturing valve, while the outlets of the distributor are associated with gate valves.      The apparatus is primarily intended for operation with pipelines of a diameter in excess of 500 mm. It offer a higher productivity than the ?ither?? known similar apparatus, ensures application of a continuous uniform layer of the coating and provides for either considerable reduction or complete elimination of the loss of the liquid coating in operation of the apparatus.

Abstract: ABSTRACT         Apparatus and methods for forming generally tubular pipe covering sections with overlapping edge portions from a sheet of elastomeric material.  For relatively thin material thicknesses the material is rolled on a male mandrel to provide a plurality of spiral wraps and this roll is heated to a selected temperature between 120°F and 150°F for at least twelve hours to effect a set in the roll.  Selected lengths of the sheet material are cut from the roll to provide tubular pipe covering sections of a se-lected circumferential size.  For relatively thick material thickness with substantial rigidity, a continuous roll of the material is cut transversely along its length to form a series of blanks.  The length of the blank is established by the width of the roll and the width of the blank is selected according to the diameter of the pipe or insulated pipe to be covered.  The blanks are preheated as they are carried on the upper stretch of an endless conveyor through a heater to a selected temperature be-tween 120°F and 180°F for a relatively short time interval to remove any memory therein.  The blank is then directed between successive pairs of power-driven rollers in a course of travel that imparts a curl to the blank to form a curled tubular sec-tion.  The curled tubular section is then confined in a tubular female mandrel of a selected size and heated to a selected temperature of between 120°F and 150°F for between about twelve to twenty-four hours to effect a permanent set therein.

Abstract: ABSTRACT     An oily mass of solids tailings is derived from flotation of bitumen during hot water extraction of bituminous sands, and subsequent separation of most of the bitumen from associated solids.  This oily mass contains a high concentration of heavy minerals, in the order of 10% by weight titanium and 4% zirconium.  The tailings are introduced into a hot reaction zone and contacted with oxygen while agitating the solids.  The bitumen associated with the solids is burned, as is residual coke left from the combustion of the bitumen.  The product particles are discrete, dry and clean.  They can be slurried with water and passed through gravity concentrating means, such as a spiral, to produce a concentrate containing in the order of 18% titanium and 8% zirconium.

Abstract: ABSTRACT           The present invention is directed to a variable volume film drum with a proportionally variable length conduit path for directing and controlling the flow of fluids introduced into the drum.  The center conduit path is comprised of interconnecting conduit reels also used to hold the film.  Each conduit reel has an internal conduit path, one end of which forms an outwardly extending flange or male portion and the distal end forms a receiving or female portion.  As the volume of the container is varied to accommodate more or less reels, the conduit path formed by the interconnected reels is proportionally altered.  The conduit reels are further connected to a fluid inlet tube in the film drum to complete an integral path for the introduction of fluids into the drum.
