Abstract: A method and apparatus for the generation of a foaming dispersion of bubbles in a carbonated beverage or other gas-containing liquid packaged in a can (120) or other sealed container. An initially liquid-free device (9) having an internal chamber with an inlet/outlet valve (130/150) assembly is placed in the can, which is then filled with the beverage. The can is sealed and pasteurized, which raises the internal pressure in the can to force some of the gasified beverage into the device through the inlet valve. The outlet valve holds the quantity of beverage in the internal chamber until the can is opened, whereupon the depressurization of the can opens the outlet valve to discharge the internal chamber through an orifice to initiate seed bubbles which form a head on the beverage. The method and apparatus are particularly applicable to producing a head on fermented alcoholic beverages to simulate draught beverages.

Abstract: A weapons-handling and discharge system for a submarine which comprises a rotatable rack for attachment around the exterior of the pressure hull of a submarine, canisters to contain weapons, an exterior casing provided around the pressure hull, forward or rearward facing apertures in the casing, and a mechanism for discharging the weapon from the canister and through the aperture. The canisters are located between the pressure hull and the exterior casing and are locked to the rack.

Abstract: A transplanter for transferring seedlings from plant trays to a planting position includes a special plant tray having a series of longitudinal indexing grooves and a transverse alignment groove for engagement with indexing rods and support rings that are joined together to form an indexing drum. The indexing drum is mounted adjacent a loading frame for guiding the plant trays into position for ejection of the plant seedlings and includes an integrally internally mounted plug ejector subassembly which moves relative to the indexing drum at each of a number of successive indexing positions of the drum for ejection of seedlings from the plant tray. The indexing grooves and transverse alignment groove on the plant tray provide datum surfaces for ensuring accurate positioning of the plug ejector subassembly relative to the seedlings in the plant tray.

Abstract: The invention relates to a rocker arm including a roller, a pair of side walls for supporting the roller, a pivot engaging portion and a valve engaging portion, in which the configuration of the valve engaging portion, and the relative position of the roller, the pivot engaging portion, and the valve engaging portion are set with high accuracy. In the rocker arm, the roller, while being in contact with a cam, is rotatably provided between a pair of side walls forming a rocker arm body. The rocker arm body is of a two-piece structure including a first piece which includes: the pair of side walls adapted to support the roller; and a valve-engaging portion through which, as viewed longitudinally of the rocker arm body, first end portions of the side walls merge with each other; and a second piece which is a pivot engaging member fixedly secured to the remaining second end portions of the side walls.

Abstract: A user of a self-powered electronic combination lock rotates an outer dial to cause generators to generate energy for storage in a capacitor bank. The user then rotates an inner dial to cause a microcontroller to sequentially display a combination of numbers, and presses the inner dial to select a displayed number. The microcontroller determines direction and extent of motion of the inner dial by receiving signals derived from Wiegand sensors placed in proximity to a magnetized disc which rotates integrally with the inner dial, and controls the display of numerals on an LCD display accordingly. When the microcontroller determines that a correct combination has been entered, it activates a motor to move a motor cam to act directly on a locking lever so that the locking lever can engage a drive cam integrally linked with the inner dial, to allow the inner dial to withdraw the lock's bolt.

Abstract: Hydrophilic glass fibers are formed by coating glass fibers with a blend of an amine-aldehyde with an acrylic. Evaporative cooler pads are produced by coating glass fibers with a blend of an acrylic and an amine-aldehyde during hot melt spinning of the glass fibers into a web, followed by drawing the web to expand the web or mat into a porous pad, and curing the pad to produce a dimensionally stable, hydrophilic, porous, glass fiber pad. Preferably, the glass fibers are coated with a binding/hydrophilic coating formed of a blend of a urea-formaldehyde with an acrylic. A method for cooling air using the hydrophilic, porous, glass fiber pads, and an improved evaporative cooler utilizing hydrophilic, porous, glass fiber pads is disclosed.

Abstract: A caulk dispenser device for use with conventional caulking cartridges and powered by expanding refrigerant liquid is disclosed. Expanding gases are released into a chamber defined in part by a housing and in part by the caulk cartridge, the plug or piston within the cartridge forming a boundary of the chamber. Discharge of the gas directly against the piston is avoided by the interposition of a deflector surface within the housing reducing the tendency of the caulk to increase in viscosity and bond to the walls of the cartridge or to tilt relative to the cartridge. The propellant liquid-gas material incorporates an increment (e.g. 5%) of perflurocarbon or like compound liquid at ambient temperatures which minimizes the cooling effect resulting from discharge of the gas. Preferably, the device is fabricated of material having a low thermal conductivity such as polymeric material to thereby reduce the cooling effect on the canister of propellant with resultant loss of pressure.

Abstract: Display apparatus includes at least two longitudinally extending members for operation in a vertical position, including at least four panel holders with two each of the holders secured to each member. A panel is held at its corners by each holder to extend between the longitudinally extending members. The panel holders include a facing pair of substantially flat, rigid plates, a rigid central member separating and interconnecting the plates, including dividing protrusions to divide the volume between the plates into pre-shaped sections. A clamping mechanism extends from one of the flat plates toward the other and movably held in relation to the other plate to clamp in place any member held within the volume between the two plates.
