Abstract: A vehicle height adjustment suspension device provides for both automatic and selective raising and lowering of a supported portion of a vehicle frame relative a ground surface, while also providing shock absorption. The device includes a suspension assembly for absorbing shocks mounted on a rotatable threaded screw connected to a motor and extending into the suspension assembly. The assembly may be extended and retracted on the screw by rotating the screw in first and second directions to raise and lower the supported portion while the shock absorber assembly simultaneously provides shock absorption capability.

Abstract: A method for producing, from passive sonar data, operational images interactively controlled by an operator, continuously adjusted according to operational requirements and compatible with changing information requirements in real time. The invention uses a method for representing a multidimensional data field on a display screen which uses the screen co-ordinates for two dimensions of data and at least one of three color perception components among luminosity, hue and saturation for three other dimensions of the data, to produce bearing-time, azimuth-time, or frequency-time (circulating lofar) or frequency-bearing images with representation of frequencies by hue or interactive filtering.

Abstract: A method of facilitating the disposal of waste cutting liquid consisting essentially of an emulsion of partly soluble oils and water comprises subjecting a trickling flow of the liquid to the action of a current of hot air at a temperature of from 80.degree. to 250.degree. C. and thus evaporating the water from the liquid. Insoluble oils may be removed from the liquid by decantation before the liquid is subjected to the current of hot air. Preferably the oil which remains after the water has been evaporated from the liquid is used as fuel in the heating of the hot air so that the oil is disposed of. Apparatus for carrying out this method comprises an evaporation tower containing a series of plates alternately inclined in opposite directions to the horizontal and arranged one beneath the other to permit a trickling zig-zag flow of the cutting liquid over the plates from the top plate to the bottom plate in the series.

Abstract: Food products, such as vegetables, fruits, etc. are efficiently sterilized and/or cooked and canned under high vacuum by filling them into containers, e.g. conventional tin cans, in the presence of only a small amount of water; then securing lids non-sealingly to the open ends of the cans; then passing the cans over a high temperature heat source for direct flame or radiation heating, with their axes inclined, until the liquid collected in a bottom region of each can has come to a boil and the steam formed has driven the free air from the can; then sealing lids tight to the can bodies; then heating the cans to the desired temperature of sterilization and/or cooking and maintaining this temperature for a predetermined period of time; and finally cooling the cans, e.g. by a water spray, whereupon a vacuum of about 700 mm. (27 to 29 inches) of mercury is formed in each can by condensation of the steam therein.

Abstract: A method of building, by means of juxtaposed modular elements a reference wall surface to be connected with and having a relative position and shape predetermined with respect to an initial wall surface, consisting in determining a nominal distance of each element from said initial wall surface; positioning said modular element thereagainst at said distance after interposition of a settable filling product therebetween for filling in the gaps left between said initial wall and said modular elements for locking same in position.
