Abstract: The invention provides a method for producing permeable polymeric membranes comprising decomposing, in a polymeric matrix, molecular moieties, bound to the polymer or contained in compounds dispersed therein, into smaller, discrete, molecular units, whereby the smaller, discrete molecular units, which are formed, spontaneously leave the polymeric matrix and a membrane of defined permeation characteristics is obtained.

Abstract: An aquarium for housing fish and other aquatic life if formed within a pyramidal housing. The upper portion of the housing is formed of transparent triangular walls which enclose the water for the fish while permitting viewing of the fish. The lower portion of the housing serves as a base for supporting the water, and includes a drawer which holds filtration, heating and aeration equipment while permitting ready access for servicing of the equipment. Lighting is provided by an internal pyramidal light situated at the apex of the housing within the walls, the location permitting lighting of the entire water surface without any significant heating of the walls. All plumbing connections for treatment of the water are made through the floor of the chamber holding the water, thereby avoiding the presence of unsightly hoses and tubing.

Abstract: The speed of feed movement of a piston is controlled to an essentially constant value by direct digital measurement of the actual speed, by comparing the actual value to a preset value and by compensating for differences therebetween. Variations in the piston feed pressure and in the grinding power are taken into account by means of additional signals related to these factors and added to or subtracted from the signal representing the actual value of the speed of the piston.

Abstract: A spherical swollen hydrophillic toric contact lens is converted into a planarized xerogel and stored and transported on a planar or moderately curved base provided with an angle scale in the range of 0 to 180 degrees. The base is formed to locate the lens above the center of the scale with the cylindric axis lying on the lines converting the 0 or 180 degrees with the center of the angle scale. A permeable cover capable of compressing the lens is placed over the lens causing the lens to assume the surface shape of the base in the xerogel state.

Abstract: A draw frame for spinning machine is provided with a blocking mechanism movable into a position between the upper and lower feed rollers in the event of yarn breakage, to lift the roving from contact with the driven rollers. The blocking member is mounted on a rail, extending parallel to a load arm on which the upper rollers are mounted. Both load arm and the bearing arm rail are swivelably mounted. Each of the bearing rails are arranged so that they are weighted by the supporting arm, when placed in the operating position, by a resilient member acting on a connecting member between the bearing rails.

Abstract: An electrical firing mechanism for hand guns and small caliber machine guns having a tension trigger which tightens a compression spring locading an impact member which when released strikes a piezo-voltage generator. The output of the generator leads to an electrical detonator. A firing mode selecting system, includes a lever which serves to engage a safety to block the trigger and to provide other firing modes such as burst and sustained fire. An additional source of electrical energy is provided in addition to the piezo-voltage generator, which can be connected with the detonator by way of the trigger, and the selecting system.

Abstract: A column and a plurality of support members having radially extending arm and/or foot portions, having an inner end portion shaped as a sector of a cylinder with an axial Morse tapered hole, and adapted to be received in the inside of the hollow end portion of the column.

Abstract: Fluid waste material is completely atomized and decomposed in a burner wherein the material to be decomposed and an oxidizing agent are maintained at a suitable relative ratio at every point in the burner so that waste transforms into a stable combustion product. Catalysts or other subsidiary materials are not required. The oxidizing agent may be air, air enriched with oxygen, or oxygen, and plasma is produced from the air or from the waste material itself. Water may be introduced into the plasma to promote the formation of hydrogen halogenides if the waste material itself contains halogens. The atomized gases may be deacidified and washed.

Supplementation with steam being effected to a relatively minor extent during normal operation of the unit but being effected to a major extent when the temperature of the bed passes outside the range at which attemperation may be effected by use of recycled flue gas. The combustion unit is described in use within an arrangement including process plant in the form of a rotary drum dryer.

Abstract: The invention relates to a fire extinguisher comprising a low-pressure tank (1) for the fire-inhibiting liquid (40) and a high-pressure tank (23) for spray propellant gas, situated in the low-pressure tank, where upon opening the high-pressure tank, the propellant expels the fire-inhibiting liquid, which is discharged through a nozzle (44).
