Abstract: Waste material is treated by mixing it with an aqueous solution of an alkali metal silicate and a silicate setting agent containing polyvalent metal ions to cause the silicate and setting agent to chemically react with each other and convert the mixture into a consolidated chemically and physically stable earth-like material substantially insoluble in water and with its pollutants entrapped. Landfill material and the treated waste material are disposed in contact with each other on land to be filled and in such relation that the leachate from the landfill material will trickle down through the treated waste material.

Abstract: A polyphase stator winding for three or more phase pole-changeable synchronous machines includes rod-type windings which are encased within each other in a multi-layer arrangement in the stator slots. The winding arrangement will permit for any pole-number pairings occurring in practice an additional degree of free-choice in the selection of the number of poles or speeds, respectively that can be paired with each other, and of the winding pitches and spread values which are advantageous in relation to harmonics content, and in relation to the spread factor and consequently the winding factor as well as with respect to losses. The arrangement of the windings is characterized by selecting, for the two windings, winding pitches which differ from one another by an integer and even constant C expressed by the relation C = w1 - w2 where (in the case of wave type windings) the constant C takes values +/-2, +/-4, +/-6 and so forth, where (in the case of lap type windings) the constant C takes the values -2, 0, +/-4, +/-6 and so forth, wherein w1 and w2 represent the slot pitches, and wherein there is provided for each winding an inter-connecting device including oblique eye-rods for at least one winding designed to bridge the gaps between the rods of the lower layer to be connected and the corresponding rods of the upper layer.

Abstract: A chemical sensitive field-effect transistor transducer capable of selectively detecting and measuring chemical properties of substances to which the transducer is exposed. The transducer includes a semiconductor substrate material having a certain doping polarity, a pair of spaced apart diffusion regions located at the surface of the substrate material and having a doping polarity opposite that of the substrate material, electrical insulator material overlying the diffusion regions and the surface of the substrate material lying between the diffusion regions, and a chemical selective system overlying the insulator material. The chemical selective system is adapted to interact with certain substances and thereby modulate an electric field produced in the substrate material between the diffusion regions. This modulation is dependent upon the chemical properties of the substances and provides a measure of those chemical properties. The chemical selective system may include various structures for measuring ion activity, immunochemical concentrations, reducible gas concentrations and the concentrations of enzymes and substrates.

Abstract: A method of operating a four-stroke internal combustion engine of the carburator or fuel injection type, with one or several reciprocating pistons or one or several rotary pistons wherein during the intake movement of the one or the several pistons an additional gaseous or liquid or gas-liquid mixture fluid is introduced into the cylinder working space through a cylinder side wall aperture in the vicinity of the piston to establish a layer charge overlying the piston. The introduction of this fluid may be effected by suction effects caused by the piston movement. The amount of fluid supplied may be controlled in dependence upon combustion pressure and/or exhaust gas composition. The internal combustion engine includes an aperture in a cylinder wall in communication with a fluid source whereby this aperture is adapted to be obstructed or exposed by the moving piston to control the admission of the additional fluid. Between the aperture and the fluid source may be provided control valve means.

Abstract: A method, and an apparatus for carrying out that method, for making roofing from a stretchable and deformable sheet material. The roofing sections are made from sheet material which has a preformed laterally sinu-soidal configuration which is reconfigured with longitudinally spaced steps (or folds). The finished sheet is a roofing section having the configuration of stepped tile roofing which is a substitute for true roofing tile. The sinu-soidal sheet is clamped (or pressed) in a tool between two adjacent pairs of complimentary shape clamping jaws. In that tool apparatus the two pairs of clamps are then moved relative to each in parallel paths normal to longitudinal and lateral planes through the sheet, which movement stretches the sheet to form a step (or fold) between the portions held in the two sets of clamps. More than two sets of pairs of tools can be used to simultaneously form multiple steps and alternatively the sinu-soidal sheet can be periodically shifted and step stretched in a continuous operation.

Abstract: In order to produce a transition mixture enrichment during acceleration of an internal combustion engine, a carburettor or other mixture generator 1 of the engine with a mixing chamber 2, a main throttle 4 and a choke valve 5, has the choke valve 5 operated by a quick-acting electric drive 6, for example a two-coil rotary setter, which is controlled by a microprocessor 8. The microprocessor is fed with signals which sense the opening of the main throttle 4 and preferably also other engine operating parameters such as temperature and speed. When the main throttle 4 is opened to accelerate the engine, the microprocessor 8 causes the electric drive 6 to close the choke valve 5 abruptly and temporarily. The extent of closure of the choke valve 5 is dependent upon the extent of the throttle opening and on the other operating parameters to give the required mixture enrichment. This arrangement avoids the necessity to provide an accelerator pump.

Abstract: In a plant for producing nuclear reactor fuel filtering of a precipitate of ammonium uranyl carbonate obtained from uranium hexafluoride, ammonia and carbon dioxide results in a solution which is treated with calcium carbonate to precipitate the fluorides in the solution and which is heat-treated to separate gaseous ammonia and carbon dioxide. The gases separated are jointly dissolved in water to form a solution which contains at least 15% by weight of ammonium ions, calculated as NH3, and at least 20% by weight of carbonate ions, calculated as CO2 and which is used in the plant for reaction with uranium hexafluoride to form ammonium uranyl carbonate. The separated gases can be dissolved using a solution already prepared from such gases. In addition to the quantity of ammonia which is fed to the uranium hexafluoride in the form of the solution containing ammonium ions and carbonate ions, ammonia may also be introduced in gaseous form. <IMAGE>

Abstract: A body to be picked up is provided with a bolt having a relatively narrow shaft embedded in and projecting from the body and a relatively wide head on the shaft spaced from the body. This body is picked up by a device having a shackle provided with a crosspiece defining a lift eye to which is connected a grab cable and a pivot eye. A pickup member is pivotal on the pivot eye of the shackle about a pivot axis and has a generally radially extending actuation arm and an axially elongated and outwardly open pickup slot lying generally in a plane perpendicular to the axis and having a relatively wide end permitting radial passage of the head into and out of the slot and an angularly opposite relatively narrow end internally sufficiently wide to accommodate the head but externally insufficiently wide to permit radial passage of the head out of the slot. This slot is internally sufficiently wide between the ends to permit the head to pass angularly along the slot between the ends with the shaft extending out of the slot. Thus the member can pivot about the axis with the bolt engaged in the slot. An arcuate locking bolt may be displaceable in an arcuate guide slot in the pickup member to block the wide end of the slot.
