Abstract: A charged particle beam recorder having a curved film gate to impart a predetermined continuous curvature to the recording film. Predetermined tension is applied to the recording film to assure good contact of the film with the curved film gate and a motor is provided to intermittently advance the film through the film gate thereby providing fresh film for exposure. The positioning of the recording beam on the film is electronically corrected for the known geometric distortions introduced by the predetermined continuous curvature of the film gate and the predetermined tension of the film.

Abstract: An apparatus for reclaiming no-bake foundry sand is provided, in which a fluidized stream of pneumatically conveyed particles of no-bake coated sand grains traveling at velocity sufficient for transport is discharged against a target to fracture the no-bake rigid coatings from the sand grains on impact. Certain of the fractured coatings are removed and the sand grains along with any remaining fractured coating particles are directed through a passageway having a fluidizing air stream induced therein. The air stream entrains and carries off the fractured coatings and the fine sand grains so that only sand grains of desired particle size pass through the air stream for subsequent reuse. Advantageously, the velocity of the air stream is controlled by regulating the cross-sectional area of the passageway at the point at which the air stream is induced.

Abstract: In applying an unthreaded metal closure to the threaded neck of a bottle by the use of profiled thread rollers to shape the skirt of the closure shell into conformity with the bottle thread while the shell is pressed down on the mouth of the bottle, the part of the skirt in which the thread is formed is engaged during the thread-rolling operation by at least one plain roll angularly displaced with respect to the thread rollers.

Abstract: A method and apparatus for vulcanizing extruded rubber profiles in vulcanizing ovens to eliminate under cure of the rubber profiles in those areas where the extruded rubber profiles contact a support means by arranging at least one microwave emitter below and in close proximity to the support means.

Abstract: A hair dyeing composition comprising a metal salt and a sulfur-containing reducing compound is described. In the composition, the metal salt is a water-soluble bismuth salt of an alpha-hydroxy, mono-carboxylic acid.

Abstract: A method and apparatus for preventing microwave leakage at a conveyor portal channel of a microwave oven where a product to be treated is moved therethrough on a conveyor means, including the steps of positioning partitions on the conveyor means which carries the materials to be heated through the portal channel, and providing spaced protrusions between the moving peripheral walls of the partitions and the portal channel walls, thereby preventing microwave leakage from the oven.

Abstract: A machine for de-capping containers having screw caps is responsive to the presence or absence of a cap on a container and includes an annular body mounted for rotation about a vertical axis and for upward and downward movement towards and away from a container. The body carries on its periphery vertical arms which are pivotable about tangentially extending axes, the lower ends of the arms carrying tools operable to grip the cap. Coaxially within the body is a plunger-like probe which is spring urged downward relative to the body and which operates a valve controlling a supply of pressure fluid to motors for operating the arms to grip a cap. If the probe contacts a cap on a container the valve is opened by the relative movement of the probe and body to operate the motors to cause the cap to be gripped. If no cap is present on the container the valve remains closed and the arms do not operate.

Abstract: A portable comparator gage for cylinders having a self-supporting configuration with a high stiffness to weight ratio to minimize the contact force and therefore "spring open" of the gage when it is placed on a cylinder, and temperature compensation means to compensate for inaccuracies in the measurements of the relative deviation of the diameter of the cylinder resulting from variations in the temperature of the cylinder and gage from a nominal temperature.

Abstract: This invention relates to internal combustion engines, the energy output of which is produced as hydraulic pressure, and in one embodiment comprises two, two-cycle internal combustion engines which face each other, the piston rods of each of which are axially aligned and are linked to both of the axially aligned drive pistons of two hydraulic pumps which also face each other by means of four connecting rods of equal length, the axis of the pump rods being at right angles to that of the engine rods, and associated hydraulic circuitry which includes means for selectively initiating the compression phase of the engines when their respective pistons have thrust outward toward each other to such an extent that the angle between the axis of each of said piston rods and its associated connecting rods has passed through a right angle and said rods would otherwise be retained in said extended position through force exerted on said connecting rods by the pistons of the hydraulic pumps.

Abstract: A glass washing electromagnetic pump comprising a cylinder in communication at both ends with two ducts, said ducts being a suction duct and a delivery duct, said cylinder containing a piston which is alternately moved toward the one or the other side of the cylinder by means of the alternate energization of two electromagnets enclosing said cylinder, so that at each movement or stroke of the piston there is at the same time a delivery action from one chamber defined by said piston inside said cylinder and a suction action in the other chamber.

Abstract: Human air is dyed in successive treatments at selected intervals with oxidation colors (aromatic primary amines and aminophenols) admixed in each treatment with an oxidizing agent (H.sub.2 O.sub.2 or a derivative thereof) -- the quantity of oxidation colorant applied in each treatment being substantially the same and the quantity of oxidizing agent being increased from the first to the last treatment to effect a gradual increase in depth of shade -- the mixture being allowed to remain on the hair for substantially the same tine in each treatment, followed by removal by rinsing.

Abstract: A high speed centrifugal compressor is closely directly coupled to the power turbine of a two-shaft gas turbine having a gas generator section separate from its power turbine. Through the direct close coupling and centerline mounting of the gas turbine exhaust casing for free and uniform heat expansion, alignment between stationary and rotating parts of the power turbine and compressor is maintained free from mechanical problems. The compressor stage assembly elements are conveniently interfitted together in the vertically split compressor casing by means of compression bolts minimizing fastening means. Bearings and oil seals are fed by an integrated lubrication and sealing oil system utilizing a compact oil distribution manifold assembly incorporating a quick filter change structure. The turbine fuel distribution system includes means permitting ready replacement and maintenance of individual fuel nozzles without disassembly of the entire fuel nozzle system.
