Abstract: A lock for a revolving door includes an electrically-controlled, solenoid-extensible trip rod engageable by a panel of the door. Movement of the rod by the door panel rotates a key from a lock holder to release a spring-biased locking element which is forced onto the door panel to prevent further rotation of the door.

Abstract: A display matrix incorporates optical fibers to transmit light from light sources to the front of the display. An occulting device is associated with an assembly of fibers to modify the character of the light emitted to the front of the matrix, and a device controlling the actuation of the occulting of device makes it possible selectively to control the occulting of determined groups of fibers to transform the display as desired. The occulting device comprises a disc incorporating different light-modifying sectors capable of being interposed in the path of the light, as a function of a rotation controlled by the electromechanical actuation device which includes a rotor coupled to the disc and rotatable within a stator made of a material having good magnetic remanence and high permeability to provide the device with a very short response time and low input energy requirement.

Abstract: Novel ultrathin unit layers and built-up multilayers are obtained when a spreadable polyfunctional aldehyde or its precursor, particularly the alkyl Schiff base formed by its condensation with an alkyl amine, is spread on the surface of an aqueous subphase containing a diamine. The resulting polymeric imine unit layers were transferred and built up on substrates which included quartz, aluminum and chrome-plated glass, and semiconductors.

Abstract: An apparatus and process for the continuous casting of tubular shapes wherein molten metal from which the tubular shape is formed is centrifugally deposited adjacent to the outlet of a fluid-cooled mold by a nozzle assembly, with the metal being cooled and rapidly solidified by the mold to form a cylindrical shell upon which additional metal is deposited to incrementally build the thickness of the tubular shape. The tubular shape being formed is withdrawn continuously from the mold, and is further cooled by coolant directed thereon. The nozzle assembly may be rotated to discharge the molten metal or, alternatively, the mold may be rotated as the metal is deposited thereon. Single-layer tubular shapes, with or without reinforcing material, may be cast and multiple-layer composite shapes may be produced having layers of different material composition and thicknesses. An inert atmosphere is maintained to prevent oxidation of the molten metal.

Abstract: Expanded particles obtained by a method including the steps of: providing unexpanded particles formed of a polyethylene resin; impregnating the unexpanded particles with a liquid containing a polymerizable monomer including an acrylic monomer, and optionally a styrenic monomer; subjecting the impregnated polymerizable monomer to polymerization conditions so that at least a portion of the polymerizable monomer is grafted on the polyethylene resin to obtain modified polyethylene particles; and subjecting the modified polyethylene particles to an expansion treatment. Further expansion of the expanded particles within a mold gives a foamed article suitable for use as a consumable pattern in full mold casting.

Abstract: An apparatus is disclosed for dispensing a fixed quantity of material, having a flexible container for holding the material and an assembly rotatably disposed within the container for measuring and dispensing the material when the container is squeezed. The assembly includes a measuring cup extending adjacent to the bottom of the container and having an opening for entry of the material, an air chamber disposed adjacent to the mouth of the container and formed with a nozzle for discharge of the material, and a tube connecting the cup and chamber. Openings are spaced around the periphery of the air chamber, and the container neck adjacent to the chamber is provided with a plurality of protrusions which can, by rotation of the assembly relative to the container, be selectively positioned adjacent to the openings in the air chamber to block the openings and prevent air flow therethrough.

The assembly includes a measuring cup extending adjacent to the bottom of the container with an opening for entry of the material, an air chamber disposed adjacent to the mouth of the container and formed with a nozzle for discharge of the material, and a tube connecting the cup and chamber. At least one opening is provided in the air chamber having a valve associated therewith which operates automatically to block the opening when the dispenser is inverted and to unblock the opening when the dispenser is upright. The dispenser is inverted and squeezed to dispense the quantity of material in the measuring cup, the opening being blocked by the valve to prevent flow of material therethrough. When the dispenser is upright, the valve unblocks the opening to permit air flow into the container and to permit refilling of the measuring cup.
