Abstract: The following disclosure teaches ways and means for incinerating organic wastes in a multiple hearth furnace equipped with an afterburner. In the furnace, the wastes are pyrolyzed in an oxygen deficient atmosphere which is regulated to only partially complete the oxidation of the organic substances which are pyrolyzed from the wastes. In the afterburner, air is introduced to complete the oxidation of the partially oxidized substances carried by gases and vapors from the furnace. The air supply to the afterburner is controlled so that, at temperatures above a predetermined temperature, the quantity of air introduced is increased with increasing temperatures and is decreased with decreasing temperatures. In other words, the pyrolyzing furnace is caused to operate with a deficiency of air over its operating range, while the afterburner is caused to operate with excess air and the amount of excess air supplied is used to control the operating temperature by quenching.

Abstract: Apparatus having fuel combustion cylinders for urging the rods of pistons operating therein through power strokes, and fluid pressure pistons, also operating in cooperating cylinders, which are correspondingly urged during said power strokes through movement causing the production of a pressure fluid which is thereafter utilized, on demand, to do work. In the transmission of said movement-producing forces of said fuel-powered apparatus input to said pressure fluid output, a linkage mechanism is advantageously utilized to provide a pressure pattern in the pressure fluid which starts at an optimum low value and progressively builds up. This effectively reverses the pressure pattern of the combustion fuel which consists of a rapid-expansion gas having an initial maximum value and, due to expansion, progressively diminishes in value.

Abstract: In fuel injection ignition systems, it is necessary to provide control of the open time of the fuel injector valves which varies with the engine speed. However, for efficient operation with a minimum of pollution, the relationship of valve open time to engine speed is not a simple relationship, and factors other than engine speed are involved. It has been found that the open time should change with engine speed by steps not directly related to engine speed. This can be accomplished by providing a waveform which varies with time across a capacitor by a regulator system which controls both increase and decrease of the voltage across the capacitor. This voltage waveform, which varies with time and is independent of engine speed, can then be combined with a ramp voltage initiated at a particular point of rotation of the engine at the time the injector valves are opened.

Abstract: This invention relates to a method of preparing dispersions of low density polyethylene waxes which can be a chemically modified polyethylene wax or low molecular weight unmodified polyethylene wax and their use in metallic paints. The use of these dispersions prevents hard settling of the metal flake in the liquid paint which was measured to be better than the use of a dispersion made from an ethylene vinyl acetate wax dispersion (AC 405 wax). Also the use of such an Epolene wax dispersion allowed the paint to be sprayed rapidly while maintaining better appearance and smoothness than without any wax or an ethylene vinyl acetate wax dispersion.

Abstract: A method and apparatus for producing apertures such as ventilation holes and the like in a preformed sheet of polystyrene foam which comprises forming slits which extend completely through the foam structure, the slits being arranged in a predetermined pattern, and passing the preslit foam through a heating zone such as a preheat oven used in plastic thermoforming operations. The resultant heated sheet of foam, as it emerges from the oven, is characterized by having a plurality of openings or apertures in locations corresponding to the slits which were made in the foam prior to preheating. The aperture containing sheets may be subsequently subjected to a thermoforming operation whereby thermoformed objects such as produce containers are produced having ventilation openings, i.e. apertures, located in a predetermined disposition around the thermoformed tray structure.

Abstract: 5,6,7,8-Tetrahydrotriazolo{4,3-a}pyridin-3(2H)-one derivatives containing a 4-(optionally substituted phenyl)piperazinyl component attached to the 2- position of the tetrahydrotriazolo{4,3-a}pyridinone component via an alkylene chain of 3 or 4 carbon atoms are disclosed.

Abstract: A novel joint prosthesis, particularly suitable as a metacarpophalangeal joint prosthesis, is disclosed comprising first and second intramedullary plugs adapted to be secured to the walls of the intramedullary canals of the two bones forming the joint, and first and second components each comprising a bearing portion and a stem slidably received in a longitudinal bore provided in each of said intramedullary plugs. Transmission of stresses to the bone-prosthesis fixation interfaces is substantially reduced as a result of the freedom of motion of the stems within these longitudinal bores. In a preferred embodiment, axial rotation of one, but only one, of said stems with respect to the intramedullary plug receiving it is prevented. Use of preferred configurations for the bearing portions of the two components provides an accurate reproduction of the movement and degrees of freedom of the natural metacarpophalangeal joint.

Abstract: In a bath waste and overflow arrangement, a system and method for easily and accurately adjusting a valve actuating linkage to the proper length. An adjustable overflow tube assembly is provided with a graduated scale that indicates the length to which the tube assembly is adjusted. The linkage has a similar scale and is adjusted in its length until such scale provides an indication corresponding to that on the first scale. This correspondence between the indicators on the scales assures that when the linkage is inserted into the overflow tube, its length is proper to accurately locate a valve plug controlled by the linkage.
