Abstract: A toilet deodorizer having a hollow housing, containing a motor-driven fan and a filter medium, mounted within the normal flush tank air chamber. The housing divides the air chamber into an intake receptacle, inside the housing, and an exhaust receptacle, outside the housing. The intake receptacle is open to the overflow conduit through an inlet aperture, and is open to the exhaust receptacle through an outlet aperture. The fan induces air from the closet bowl through the overflow conduit, and thence through the filter into the exhaust chamber, thereby deodorizing the closet bowl.

Abstract: A process for making hollow metal microballoons from alloys which include a base material capable of absorbing a gas when molten and then subsequently desorbing said gas during solidification and one or more glass formers. The alloy is melted and atomized in an inert atmosphere to form a clean, dense, unoxidized powder which is screened and then subjected to a reactive plasma, melting the particles and generating a gas which is absorbed in and inflates the particles. The gas desorbs from the microballoons as they solidify; and impervious, glassy films form on their surfaces.

Abstract: Apparatus for the treatment of animal feedstuff prior to pelletizing thereof comprising a conditioning vessel and at least one sterilization vessel, each of which is in the form of a cylindrical drum, means for feeding the material to be treated through the conditioning vessel where steam or other a additive can be applied, means for passing material from the conditioning vessel to the sterilization vessel or vessels and means for discharging material from the sterilization vessel or vessels after a required residence time therein, said conditioning vessel and said sterilization vessel or vessels being arranged in spaced apart relationship and connected by walls to form an integral structure having a single chamber between said vessels through which a heating medium may be passed, thus to heat the contents of both the conditioning vessel and the or each sterilization vessel.

Abstract: A closure assembly for a glass canning jar has an internally threaded skirt portion and a transverse lid portion having a rim section separated from a center section by a continuous weakened region in the form of a surface groove. A manual pull member is mounted on the center section. The transverse lid portion may be integral with the skirt or may comprise a separate member.

Abstract: A microtest plate is characterized by a tray conveniently moulded of foam plastics, having a multiplicity of compartments and a multiplicity of individual wells fitted into the compartments, at least some of the wells preferably being moulded integrally with one another, and preferably being arranged in one or more rows.

Abstract: An open fireplace with an air distribution system for heating one or more rooms and including a heat exchanger and an electric fan for forcing air through the heat exchanger thence through the air distribution system. Incorporated into the fireplace system is a flow control apparatus at the heating air outlet end of the heat exchanger providing fluid communication of heating air into the distribution system or through a by-pass communication back to the immediate area in which the heating air inlet to the heat exchanger is located. The flow control device includes a damper which is positioned in response to a heating air condition such as flow or temperature to divert heating air from the distribution system into the by-pass to avoid excessive air temperatures in the distribution system.

Abstract: An applicator device comprises two casing parts pivotally connected for movement between a longitudinally aligned closed position and a folded open position, one of said casing parts providing a tape supply chamber and the other providing a chamber for receiving and accumulating the tape after use. A flexible member anchored on the one casing part extends between the casing parts for forming a backing for the exposed material when the casing parts are relatively pivoted to said open position, and the flexible member at the same time acts to advance material out of the supply chamber and toward the other casing part. Unidirectional pawls in the other casing part are effective when the casing parts are relatively pivoted to closed position for preventing retraction of the tape.

Abstract: Copolyimide foams made from lower alkyl esters of tetracarboxylic acids and two or more diamines. Precursors for such copolyimides. Processes for making the precursors and for converting them to copolyimide foams.

Abstract: A retainer and display package mounting a container-dispenser that projects upwardly through a retaining opening in a top wall alongside a transparent cap enclosing a capsule seated on the top wall. The capsule is intended for incorporation in the container-dispenser in use, and the bottom wall must be removed and the cap detached to extract the container-dispenser and capsule for use.

Abstract: A method for start-up and an electroslag remelting furnace system having a bottom pouring device connected to a mold in which at least one electrode is remelted to form an ingot. The bottom pouring device is positioned to receive molten slag and pass it through the lower part of the furnace mold until it rises in the mold and contacts prepositioned current conducting elements in order to complete the electrical power circuit of the furnace. The system includes a slag transfer apparatus which is either located or is shiftable to a location adjacent the bottom pouring device. Pouring of the molten slag is controlled responsive to correlated slag level and contact with the lower end of the electrodes.

Abstract: Methods of modifying the viscosity of bituminous materials in which a fluoro or chlorofluoro derivative of a lower alkane is mixed therewith, and processes involving and employing products so modified.

Abstract: Apparatus for securing a trim strip or mullion to two adjacent wall panels. The apparatus is particularly useful in securing a mullion to the forward edges of the adjacent portions of the liners of the fresh food and frozen food compartments of a side-by-side refrigerator.

Abstract: An accumulating conveyor of the kind which is adapted to feed articles thereon towards the downstream end thereof to replace any removed therefrom comprising longitudinally extending laterally spaced conveying surfaces adapted to support articles which are to be fed towards the downstream end of the conveyor, and an endless conveying band is disposed between the conveying surfaces. A selected portion of the band is adapted to be moved from a lowered position to a raised position wherein it engages the underside of articles bridging the conveying surfaces to progress them towards the downstream end of the conveyor to replace any removed therefrom.

Abstract: Methods of forming metallic workpieces into ring-shaped components of selected cross-sectional configuration in which roll electrodes both heat the workpiece by electrical resistance and provide the pressure so that the workpiece becomes plastic and flows into the wanted configuration.

Abstract: A hydraulic motor is located inside a drum which is shown as a capstan. The motor is mounted in a support tube/rod unit which in turn fastens to the fixed support using a three point fastening flange. The motor is fastened with its drive shaft facing away from the fixed support and directly connected to one end of the drum, the other end of the drum being journalled on the support tube/rod assembly. Both ends of the drum can be journalled on the support tube/rod. Suitable hydraulic lines can be passed through the support tube/rod assembly to power the hydraulic motor.
