Abstract: A toy audio generating device is disclosed for use as an accessory to another toy, for example as a backpack for a toy action figure. The toy audio device includes a receptacle defining an enclosure containing a speaker and plural batteries laid out side-by-side adjacent the end of the speaker opposite the sound projecting portion of the speaker. A printed circuit board containing circuitry for generating audio signals is located in a space alongside the speaker under a side wall of the enclosure. A switch for activating sound generation is mounted to that side wall and directly contacts the printed circuit board.

Abstract: In a device for the electrical connection of preferably ALS sensors in or on roller bearings of truck wheels, a seat casing is provided for the transfer of the ALS sensor's signals from one side of the bearing ring to the other, which seat casing is located between the bearing ring and, e.g., the shaft. It serves as signal conductor or it is equipped with conductors consisting of wires, flat band conductors, conductive layers, or the like. The connection to the ALS sensor or a plug ring with a connecting cord, occurs preferably by way of slip rings 10, to exclude all operational interference induced by a creeping motion in a circumferential direction of the otherwise fixed bearing ring. In addition, without conductors or a cord the bearing will be simpler to assemble.

Abstract: A rolling bearing for longitudinal movement has a cage with its inner surface surrounding a shaft. The cage has axially extending races for loaded balls and axially extending return races for unloaded balls, as well as a cover on each of its two ends. Each cover has turn around races connected between the ends of a race and a return race. The races, return races and turn around races have slits extending along the races and open to the shaft. Each turn around race in the covers is bounded by a curved shoulder section on the inner surface of the cage and extending along the turn around race, and a curved inner wall section of the cover extending parallel to the curved shoulder wall section of the cage.

Abstract: An automatic method to repair circuit shorts and near-shorts present in narrow bridges or remnants of bridges between circuit lines. By applying a voltage across a pair of lines, certain electrical phenomena take place at the area of the short or near-short. The electrical phenomena thus generated induce a localized etching in either a gas-phase or liquid-phase medium depending upon which embodiment is used.

Abstract: A method of producing needled, structured and patterned velour textile web of nonwoven fleeces and fibrous textile material, wherein at least one layer of textile fibers, particularly staple fibers, creating a pattern is applied to at least a part of an at least single-ply pre-needled support fleece web by at least one of the characteristics selected from the group comprising color, form, material, degree of fineness and orientation, and, finally, subjecting the web to an additional one-step or, if applicable, multi-step needling for the patterning or structuring, with the fibers applied to the support web being pushed through the web until they become visible on the lower side of the web, with the pile of the fibers coming to rest substantially in the plane of the lower surface of the web and wherein the web lies for processing during all steps on a brush belt with a homogeneous surface formed by the tips of the bristles of the brush belt.

Abstract: In an apparatus which applies periodic pulsation to a solution flowing through a conduit while undergoing perfusion by a pump, a first valve is disposed in the conduit downstream of the pump, a bypass line is provided to the conduit downstream of the first valve, and a second valve is disposed in the bypass line for withdrawing some of a first pulsed flow formed in the conduit by opening and closing the first valve, through the bypass line as a second pulsed flow. A valve driving circuit periodically opens and closes the first valve and second valve at predetermined time schedules so that the second pulsed flow is superimposed upon the first pulsed flow to form a waveform in the conduit. Any desired pulsatile waveform can be obtained by adjusting the pulse width, the crest values, the delay time, etc., of the two pulsed flows.

Abstract: A gas burner used in glass melting furnace comprising a mixing tube having a perforated mixture for mixing fuel gas with air inspirated by gas flow, means for supplying fuel gas to the mixing tube and an inspiration tube located in the mixing tube. The perforated mixer is situated inside the mixing tube at the end of the inspiration tube. The gas burner also comprises a means for moving the air inspiration tube longitudinally with respect to the mixing tube and a seal located between the perforated mixer and the inside surface of the mixing tube to allow the perforated mixer to move longitudinally with respect to said mixing tube.

Abstract: A compositive functional laser printer which is made not only to form a picture on a photo-sensitive drum but also to read out a manuscript by scanning laser beam by using a hologram disk. The laser printer comprises a laser beam generator, a beam splitting unit, a beam diffractive scanning unit, a picture forming signal control unit, a manuscript reading signal control unit, and a signal detecting and storing unit, so that a picture is formed on the photo-sensitive drum, as well as the content of manuscript can be read. According to the invention, since printing function as well as manuscript reading function can be carried out, functions of duplicator, facsimile and laser printer can be carried out by one instrument, therefore the low cost of optical unit can be obtained and the product can be miniaturized.

Abstract: A cassette front loading apparatus for DAT of tray type which loads and unloads a cassette by moving horizontally and vertically is disclosed. Without utilizing separately the loading motor and the lift and drop motor for moving the cassette horizontally and lifting and dropping the same, with existing capstan motor only, the loading and unloading operation including the horizontal and vertical movement, slider opening movement, cassette take out movement and location detecting operation and the like are executed. Accordingly, the loading motor and the lift and drop motor and the number of parts are deleted, consequently all of the mechanism is very much simplified, therefore the preciseness and the durability are expected to be enhanced. Since all of the mechanism is simplified, the cost of the product is decreased and the assembling process became easier simultaneously the productivity is remarkably increased.

Abstract: A process for sterilizing biological waste such as medical waste and a biomass fuel product from sterilized waste are disclosed. The biological waste preferably includes waste capable of sorbing substantial amounts of a liquid fuel having a boiling temperature higher than about 240.degree. F. The waste is shredded and then introduced into a container holding the liquid fuel, which is maintained at atmospheric pressure at a temperature between about 240.degree. F. and the boiling temperature of the liquid fuel. The shredded waste is immersed in the liquid fuel for a time sufficient to effect sterilization of the shredded waste. Thereafter, the sterilized shredded waste is removed from the container, and ground to either make it pumpable or increase its pumpability, and to further destroy the physical shape of the waste as to make it unrecognizable. The ground waste is then pumped to a desired location. The waste with sorbed liquid fuel is atomizable and usable as a fuel for many applications.
