Abstract: A method of disposing of medical waste is disclosed wherein medical waste generated at a facility such as a hospital, clinic, and/or a doctor's office, after being bagged and sterilized, usually by a stem autoclave, is delivered to a mobile carrier having a shredder or similar device, for finely-dividing the sterilized waste which is then compacted and transferred to a storage area on the carrier where it can be commingled with sterilized shredded medical waste obtained from other facilities having been processed in like manner, before being transported to a sanitary disposal site.

Abstract: A process for the manufacture of bis-methylene spiro-orthocarbonate (BMSOC) wherein methyallyl chloride is subjected to the action of chlorine gas to form a mixture of 1,1-dichloromethyl ethylene and other chlorinated hydrocarbons which need not be and are not separated. The mixture is merely treated wich an alkali metal acetate such as sodium acetate to yield an easily separable second mixture by fractional distillation. The desired 1,1-diacetoxymethyl ethylene is thus recovered in high yield. It is then converted by transesterification in over 90% yield to the bismethylene spiroorthocarbonate (BMSOC). BMSOC is useful as a component for coatings composites, adhesive formulations and the like, which have the unique ability to (a) cure by free radical initiation and (b) expand during cure. BMSOC may be used as a component for dental composites, i.e. filling materials, because it reduces the possibility of leakage at the margin, i.e. at the composite-enamel interface and as a component in bone cements.

Abstract: A rotary-vane internal combustion engine comprising, in combination, a rotary compressor for forming and igniting a combustible fluid mixture, a rotary power unit, and an expansion chamber that is connected both to the compressor for receiving the ignited mixture, and to the power unit, where the power developed by the expanding ignited combustible mixture in the expansion chamber drives a vane acting on a driven member.In each of the compressor and power units respective rotors are mounted for rotation. A plurality of vanes rotatably supported by a shaft within each rotor rotates with the rotor and slide in slots in guides mounted with the rotor. The rotor within the compressor is mounted eccentrically so that the fluid is compressed before it is ignited and leaves the compressor.The combustible fluid, after ignition, enters the expansion chamber where it drives one or more vanes coupled to the rotor mounted eccentrically within the rotary power unit.

Abstract: A laminated noise attenuation panel for both sound absorption and sound transmission loss having as its principal layers an expanded thermoplastic core with alternately inverted cavities, half opening to each side of said core and a sheet of cured resinous material having hollow microspheres with substantially reduced atmospheric pressure randomly dispersed in said resinous material, said cured resinous sheet facing away from the noise source. The cavities of said core panel facing away from said noise source may be filled with cellulose. The side of said core panel toward the noise source may include a laminated layer of a perforated material and a decorative layer. The side of said panel away from the noise source may also include a layer of other materials and a decorative layer. Data for the noise attenuation properties of various combinations of laminations are presented.

Abstract: An electronic lock having two normally open electrical contacts as input means, the closing and reopening of said contacts sequentially resulting in the entry of a binary code into a shift register. When the contents of the shift register match a predetermined but resettable programmed code, an integrating one-shot delay is triggered and a relay activated after the delay to open the lock. Momentary or continuous operation may also be programmed and reset for the lock. A power reset function is included to clear the shift register when initial power is applied or in the event of a power failure. The input means may be activated by a single three position, spring return switch or two push buttons.

Abstract: A lightweight removable combination air and insect control panel for mounting on the internal or external sides of window frames in situ for the tight sealing thereof, said panel having two portions, a full frame portion having a sheet of rigid transparent material in its upper second and a sheet of screen material in its lower section, both being tightly secured in a lightweight frame structure. A second half-frame portion has a sheet of rigid transparent material secured in a similar half-size perimeter frame sized to fit over the screened section of the full frame portion. The frame structure also includes grooves for the insertion and securing of flexible weather stripping to ensure a tight retention of the screen material and a tight seal against the window frame. Two circular loops at the top of the panel engage corresponding hooks on the window frame. A minimal number of side and base spring loaded fastening means are used to secure the combination control panel in its sealed position.

Abstract: The target of a television camera tube comprises photoconductive material in the form of a regularly interrupted structure so that both the photoconductive material and parts of the signal electrode are accessible to the electron beam. The potential difference between the signal electrode and the cathode is adjusted so that during scanning, the signal electrode accepts a proportion of the beam current dependent on the local potential of the photoconductor surface, and the photoconductor is stabilized only during fly-back. The camera tube thus has an adjustable inherent amplification without increased inertia.

Abstract: An infra-red imaging device consisting of two sheets of interconnected disks of piezoelectric material, at least one of which has a ferroelectric transition temperature. A metal foil is provided between the sheets and mutually parallel, conductive strips are provided on both outer surfaces of the assembly thus formed, the direction of the strips on the one surface differing from that of the strips on the other surface. A generator for periodic signals which can be sequentially connected to each strip on one of the surfaces of the first sheet generates therein, via a piezoelectric effect, ultrasonic vibrations which are intercepted by the other sheet which converts these vibrations into electric signals. These signals are amplified and carry the image to be examined.

Abstract: In a luminescent layer which is composed of spatially separated areas for reduction of lateral light dispersion in the layer, this subdivision is realized by provision of a crack structure in the luminescent layer.This crack structure is realized by thermal treatment of a layer which is provided on a substratum, and can be made optimum by an appropriate choice of the layer thickness, so that deposition in a plurality of sublayers can be advantageous. The crack structure can also be caused by a pattern which is provided in the substratum surface or by means of a gauze which serves as a substratum.
