Abstract: A deenergized solenoid operated valve normally closes the drain line of a sink, basin, tub or toilet bowl, the valve thus serving as a stopper. When a pushbutton switch is closed, the solenoid is energized to retract the valve and open the drain, a flow responsive switch maintaining the solenoid energized until all of the water has drained from the sink or bowl. A float responsive switch will also energize the solenoid to retract the valve and open the drain if water accumulates from a leaky faucet. Whenever water is drained, the low pressure or vacuum that results produces an accompanying venting action. The invention may be used with a P or S-type drain connection and/or with a conventional stack vent, but does not require that any of these be employed.

Abstract: A double valve construction selectively provides a full flush or a partial flush from the tank of a toilet. The apparatus, which may be utilized to modify existing toilet water closets, includes a hollow cylinder with a first valve on its lower end engageable with a first valve seat on an upper end of an outlet from the tank. The upper end of the cylinder defines a second valve seat and a second valve is engageable with the second valve seat. As an operating handle is selectively moved through a first range of travel, it disengages the second valve from the second valve seat for a partial flush and as the operating handle is moved through a second range of travel, it disengages the first valve from the first valve seat for a full flush. The volume of water utilized in a full flush is adjustable, and a mechanism is provided for holding the first valve in its open position until a full flush has been achieved.

Abstract: A flush tank is provided including a lower outlet opening and internal structure for guided movement of a free spherical buoyant valve ball into seated position in the outlet opening of the tank after the flush water has been drained therefrom. The tank includes a float controlled water inlet valve and float operated structure for at least partially unseating the valve ball from the water outlet in response to the level of water within the tank exceeding a predetermined maximum established by the float controlled water inlet valve, in the event of a malfunction of the water inlet valve to completely terminate the entrance of water into the tank as the level of water reaches the aforementioned predetermined maximum. Further, the lower outlet opening includes an upwardly facing annular concave spherical seat of the same radius of curvature as the valve ball and the seat is defined by a tapering peripheral lip portion of a resilient valve ball seat.

Abstract: A launching mechanism is provided for ejecting a small buoy from a high sd deep depth submersible. The buoy is held in place and constrained by a pair of latch levers that lock into a groove in the buoy tail piece. The latch levers are held in place by locking pins. On launch a solenoid valve is operated allowing ambient sea pressure to actuate a release system. The sea pressure retracts a release piston assembly to which the locking pins are attached. Upon withdrawal of the locking pins, the latch levers are released by the force of neg'ator ejection springs. The ejection springs accelerate an open ended cage containing the buoy through a four foot displacement. The buoy strikes a plunger actuating a muzzle plug release mechanism that permits ejection of the buoy from the launch cage.

Each blade bears on the wall not only at its leading or scraping edge but also at a trailing or bearing surface, so as to center the shaft and facilitate its rotation, so as to hold the edge in uniform relation to the wall, and so as to bias the edge of the blade against the wall.

Abstract: A wiping arrangement for wiping a vehicle window has an elongated wiping element turnable about an axis and arranged to contact the vehicle window during such turning so as to wipe the same. The wiping element has a coefficient of friction which differs in the direction of elongation thereof. In accordance with a method of manufacturing the arrangement, a coefficient of friction which differs in the direction of elongation of the wiping element is imparted to the latter. The coefficient of friction of the wiping element may differ from one to another end of the latter in a stepped manner or in a stepless manner. The different coefficient of friction may be imparted to the wiping element by chlorinating of the latter so that different longitudinally spaced portions of the wiping element are exposed for contacting with chlorine during different times.

Abstract: A door closer is connected to a door. The movements of the door cause a piston member in the door closer to pump a pressure medium through a flow duct. There is also a flow limiting member influencing at least the speed of the opening movement of the door, and this flow limiting member cooperates with an adjustable activating element which, at a desired opening moment mechanically sets the elements of the flow limiting member in a position considerably increasing the flow resistance of the pressure medium. This brakes the movement of the piston member, and thus, also the movement of the door.

Abstract: A hinge component for pivotally connecting two parts of a piece of furniture includes a fastener member adapted to be attached to one part of the furniture, a carrier member mounted in the fastener member for adjustable displacement relative thereto along a first axis, and a hinge arm member which carries a hinge shaft defining the pivotal axis of the hinge component. The hinge arm member is mounted in a guide groove formed in the carrier member for adjustable displacement relative thereto along a second axis perpendicular to the first axis. After the carrier member is adjusted relative to the fastener member, and the hinge arm member is adjusted relative to the carrier member, the hinge arm member can be clamped between the carrier and fastener members. Thereafter, the hinge arm member can be adjustably displaced relative to both the fastener and carrier members along a third axis perpendicular to both the first and second axis thus providing three degrees of freedom for the hinge shaft.

Abstract: A method and apparatus for shirring sausage casings in which in the method the casing is moved in a direction of its longitudinal axis and while so moving has a force applied to shirr the casing which moves about the longitudinal axis of the casing. At the same time that the force is applied to shirr a force also is applied to oppose the movement of the casing. Also, the casing may be restrained against twisting about its axis upstream of the application of the shirring force. The apparatus includes rollers for forwarding a collapsed casing, an annular element adapted to rotate about the longitudinal axis of the casing to shirr the casing and a backing element adapted to hold the forward end of the casing in a fluid, tight manner and having a passage through which an inflating gas may pass to inflate the casing.

In a second embodiment the side nozzles oscillate about the axis of the rotary vertical pipe and the supporting and positioning rack is stationary.

Abstract: A ratchet buckle for tightening and tensioning straps includes a bifurcated frame member having a pair of oppositely positioned parallel arms, between which a reel member and ratchet wheels are rotatably mounted. A strap to be tensioned is reeved through the reel member.
