Abstract: A wrist watch band comprises a plurality of metallic band links connected by a continuous flexible connecting member in a non-expansile condition. The links are made of pairs of upper and lower strips fixed to each other on respective opposed surfaces thereof. The watch band can be varied in appearance by changing the shapes of the respective upper strips. A method of manufacturing the watch band comprises a sequence of steps which includes forming a series of respective upper and lower strips, fixing the respective upper and lower strips to each other, inserting a flexible connecting member into a series of aligned openings formed and defined between the upper and lower strips and cutting the links and connecting member into designated band shapes. Thus, the method permits watch bands to be manufactured efficiently and at reduced cost.

Abstract: A piece of luggage or other container has a wall with a protruding structure which is adapted to be moved into a recess formed in a co-acting frame, with the protruding structure and frame having inter-engageable portions which extend along two sides of the protruding structure and recess and converge toward one another and have shoulders movable into an interfitting relation securing the container to the frame when the container is moved in a predetermined transverse direction generally perpendicular to the direction in which the protruding structure projects from the side wall of the container. The protruding structure is releasably retained against reverse transverse movement from the interfitting relation by appropriate holding structure, desirably taking the form of a key operated locking unit carried by the frame and engageable with the protruding structure of the container.

Abstract: A camera which includes film transport means for moving a strip of film past a lens and shutter assembly in a stepwise, frame by frame sequence, with the film being maintained stationary when the shutter is in the open position. A toothed driven gear is in operative engagement with a film driven reel. A mutilated drive gear having a toothed portion with an end gear tooth and a smooth peripheral portion is rotated in time relationship with the opening and closing of the shutter. The driven gear contains a space between adjacent gear teeth (as by removing one gear tooth) whereby the end tooth of the drive gear is received in said space to facilitate the smooth "meshing" of the drive gear with the driven gear.

Abstract: In order to train a dog not to bark, a device attached to the dog's collar emits a characteristic sound whenever he barks, which sound may be accompanied on some occasions by a light electrical shock acting to condition the dog to dislike the sound more than he otherwise would.

Abstract: A kit for use in selecting a proper spring bar for use in connecting a watch band to a watch case, and including a container holding a supply of spring bars of different lengths and types, a gauge part having portions of different widths adapted to be received within and measure differently dimensioned recesses or gaps in a watch case into which a band is to be connected, and coding markings on the gauge part and bars indicating which bar in the container will fit a particular case which has been measured by the gauge part.

Abstract: Apparatus and methods are provided for reducing solid combustible particles by heat and abrasion to a condition in which they can be burned completely and without the production of objectionable solid particulates in the exhaust gases. Solid combustible particles are carried into an outer chamber of the device by a low pressure transport air stream, with additional air at high pressure and high velocity being introduced into the same chamber in a relation driving the solid particles rapidly and circularly within the outer chamber and about an inner chamber of the device. Impingement of the particles against one another and/or the walls of the outer chamber during such swirling motion, supplemented by partial oxidation of the combustibles, raises the temperature of the particles and comminutes or reduces their sizes to form a very highly combustible flowable aerosol mass which will burst into flame when contacted by a stream of secondary combustion air.

Abstract: Apparatus for delivering different additive fluids in controlled amounts to equipment utilizing those fluids, such as laundry or dishwashing equipment, with the apparatus including valves for passing the different fluids to a pump unit, desirably actuated by individual timers controlled by separate product control switches, and with the apparatus acting to automatically feed flushing water past the discharge sides of the valves and through the pump after each operation of the equipment to clean the system of the additive fluids in preparation for a next successive operation.

Abstract: A high-strength, light-weight, fired clay body which is characterized by relatively greater surface oxidation than interior oxidation with accompanying surface layer shrinkage. The clay body is quick-dried and quick-fired to substantially uniformly oxidize the surface layer to maturity while maintaining the interior of the body in a relatively unoxidized and unfired condition.

Abstract: A radio assembly to be installed in a motor vehicle and including a thin box-shaped radio broadcast receiver having a built-in cartridge tape player, a transceiver having a main section of hook-shaped box form attached to the rear of the receiver and having a separate operating section, and a microphone carrying that operating section.

Abstract: An elongated tube (preferably stainless steel) is maintained at a temperature of at least about 1000.degree. F. throughout its length. Coal or other carbonaceous feed material is moved through the tube at a uniform rate of speed in the substantial absence of air, with the feed material being constantly churned or turned as by a screw conveyor. The churning of the feed material and the diameter of the tube is such that the material is subjected to "shock" heating, whereby gases and vapors are violently released from the solid mass and are removed therefrom at a vacuum of from about two to about five inches of mercury, with said gases and vapors passing through the aforesaid churning mass. The residue is recovered and the gases and vapors are subsequently passed through conventional condensers and scrubbers to liquify the oil and separate the gases and the water.
