Abstract: A container dispenser including a reversible pouring spout and closure which in one position provides a closure for the container and which in the reverse position provides a spout for pouring liquid from the container. The dispenser includes a collar with an internal, annular gasket, the collar being mounted to a wall of the container, and a dispensing spout having an outer threaded end portion threadable from either end into the collar. The spout has an open end and a closed end with a side opening spaced from the closed end, the threaded end portion of the spout extending on either side of the side opening. When the spout is threaded from either end into the collar, the threaded portion of the spout sealing engages the gasket with the side opening of the spout open to the container interior.

Abstract: A miniature hearing aid unit to be fitted to and carried on a person's head; there being a directional microphone in the housing which has front and rear sound admitting openings to respectively supply sounds to the fore and aft ports of the directional microphone; the rear opening in the hearing aid housing being located significantly closer to the inner side of the housing than the forward opening so that the alignment between front and rear openings is at an oblique angle of approximately 20.degree. relative to the frontal direction.

Abstract: A wafer basket and a carrier easily attached and detached to an end wall of the basket. The wafer basket has upright side and end walls and an open top and bottom, with lower edges of at least two of the opposing walls having supports lying in a horizontal plane for resting the basket on a horizontal surface. At least one end wall has upper and lower edges which are adjacent the top and bottom of the basket, the lower edge being spaced above the horizontal plane. The carrier comprises a handle with a vertical plate at its lower end configured to lie against the one end wall of the basket. The lower edge of the plate has an upwardly and inwardly slanted lip configured to hook underneath the lower edge of the one end wall, and the plate also has an inwardly and downwardly oriented hook spaced above its lower edge and configured to hook over the upper edge of the basket end wall.

Abstract: A telescoping cleaning tool adapted to remove debris and the like from a poorly accessible surface. The tool includes telescoping inner and outer tubes wherein one end of one of the tubes is adapted to receive air under pressure, as from an air nozzle, and the opposite end of the other tube is provided with a sharpened edge for scraping debris and the like from a surface. An orifice is provided adjacent the sharpened edge for directing the air under pressure against such debris. The one tube is preferably provided with a handle near its air-receiving end so that an operator may grasp the handle with the fingers and press the air-receiving end into an air nozzle held in the palm of the hand, thereby permitting the tool to be used with one hand only.

Abstract: A wave-actuated bilge pump for pumping foul bilge gases from a boat. The pump includes a generally inverted U-shaped section of hollow tubing with generally downwardly directed legs having open ends. One of the ends is positioned to receive bilge gases from within the boat, and the other end is immersed below the surface of the water outside the boat. A freely-opening check valve permits bilge gases to flow within the tubing only away from the fume-receiving end. A gas-escape port opened to the atmosphere is provided in the tubing above the lower, open tubing end immersed in the water, and a second, freely-opening check valve is provided to permit flow of bilge fumes through the port only outwardly of the tubing of the atmosphere. Wave-action causes the level of water in the exterior leg of the tubing to rise and to fall such that bilge gases are drawn into the tubing as the water level falls, and the gases are exhausted from the tubing as the water level rises.

Abstract: A baler for baling refuse and having a pressing platen and a platen guide. The platen guide includes spaced sets of rollers bearing inwardly against opposed sides of the baler, and brackets rigidly attached to the platen and extending externally of the baler for mounting the rollers in engagement with the pressing box sides.

Abstract: This invention pertains to a hot plate and more specifically to an industrial hot plate for use in highly corrosive environments where chemicals of high acidity or high alkalinity are employed. An epoxy foam is utilized both to thermally isolate the heated surface from the base structure and to protect the heating element and the associated electrical circuit from damage from the active chemical agents that may be involved upon using the instant hot plate.

Abstract: A method and apparatus for deodorizing waste gases containing foul-smelling constituents that are chemically decomposable on being washed with aqueous acid formed by dissolving an acid-forming gas, such as chlorine or sulphur, in water and wherein the waste gas is washed with the aqueous acid containing a suspension of one or more alkaline earth metal carbonates, such as magnesium carbonate or calcium carbonate. In a vessel, the carbonate suspension may be sprayed downward at the top, and the waste gases directed upwardly at the bottom. Both the suspension and the gases pass through loose layers of limestone intermediate the top and bottom of the vessel.

Abstract: A rotary action electric razor which has a blade with heads rotating in an annular, slotted comb, is sharpened by inserting between the blade heads and comb a flat, annular, flexible disc having a sharpening abrasive surface and having a tab extending generally normal to the plane of the disc and away from the slots in the comb.

Abstract: A metering pulse pump for metering an additive liquid into a liquid carrier under high pressure. A high-pressure, rapidly reciprocating piston pump is provided at its outlet end with a pressure-relief valve including a spring pressure control permitting the valve to open under varying pre-set pressure differentials across the valve. A diaphragm pump having first and second chambers separated by a diaphragm is provided with one of the chambers communicating directly with the outlet of the piston pump upstream of the pressure-relief valve, liquid carrier emitted under pressure from the piston pump serving to drive the diaphragm pump in a pumping stroke, the second chamber of the diaphragm pump having inflow and outflow ports with respective check valves permitting only inflow and outflow of an additive liquid into and out of the second chamber.

Abstract: A disposable phlebotomist's tourniquet comprising a flat solid, elastic band of a length sufficient, when stretched, to encircle the human upper arm and including adjacent one end a relatively non-stretchable pressure-sensitive adhesive strip protectively covered for storage by a protective liner of treated paper or the like having one end projecting beyond the end of the adhesive strip as a graspable pull tab so that the liner may be pulled away.

Abstract: A slurry pump including a pressure tank with an inlet and a lower outlet and having a pneumatically operated, inwardly opening closure at the inlet and a hinged, outwardly opening door at the outlet swingable between opened and closed positions. An external source of air under pressure hydraulically shuts the closure and pressurizes the tank, forcing a semi-liquid slurry such as liquid manure contained within the tank through the outlet and into a duct leading to a lagoon or the like. A slurry level sensor shuts off the supply of air to the tank when the slurry reaches a given level in the tank.

Abstract: A baler having an improved hydraulically driven toggle mechanism for operating a baler pressing platen, improved bale ejector, and improved baler door latch. The toggle mechanism includes opposed pairs of first and second arms .Iadd.foldably joined together at their ends with their other respective ends joined to a pressing box and a pressing platen. The opposed sets of arms are mutually oriented so that as the platen is moved to a withdrawn position, the first and second arms of one set interfold compactly and without interference across the respective first and second arms of the opposed set .Iaddend. .[.and second arms, each first arm of which is a generally C-shaped bell crank arm. The first arms are connected.]. to provide a pressing mechanism which is compact but nonetheless has a long pressing stroke to facilitate production of a large bale in only a few pressing strokes.
