Abstract: ABSTRACT OF THE DISCLOSURE         A faucet valve comprised of a valve body having a valve seat onto which is adapted to movably and freely rest a disc-shaped valve plug.  An operant shaft having a central cam surface is journalled within the valve body, being arranged with the cam surface lying adja-cent to the valve plug so that rotating or sliding the shaft causes the plug to tip off the valve seat.  The plug is held in closed posi-tion solely by upstream pressure.  A novel check valve is also dis-closed for replacement of the standard washer in a faucet and for use with a "speedway" connection according to another embodiment.  The faucet valve is adapted to be fixed to the spout of a tap assembly having hot and cold water, in combination with the check valve, the latter preventing backflow between the two faucet conduits in the event of a pressure differential.  The faucet valve may be used independently as may the check valves.  In combination, the faucet valve and check valves eliminate the need to adjust the faucets for a desired water temperature for each use.  The faucet valve, when mounted on the common spout of the two faucets and being easily accessible and actuated, serves to eliminate water waste.  In another embodiment, the faucet valve is a flow directional valve used, for instance, to feed water to a water treatment apparatus when shutting off the spout.

Abstract: ABSTRACT OF THE DISCLOSURE           A fuel priming system for spark ignited internal combustion engines includes a manually actuated plunger pump for delivering liquid fuel from a tank to a reservoir chamber formed in part by a flexible diaphragm. A fuel injection passage leads from the reservoir chamber through a flow restricting orifice to an injection point formed in the engine intake air flow passage downstream of the carburetor venturi.          The injection system provides for enriching the fuel-air mixture during cold starting while minimizing the chance of engine flooding. The finite fuel volume in the reservoir chamber also provides a sufficient quantity of fuel for automatic control of a rich fuel-air mixture during engine warm-up.

Abstract: ABSTRACT OF THE DISCLOSURE          Mechanism for cleaning and drying compressed gas (10) includes a housing (12) having an open end closed by an end cover (14).  A desiccant canister (16) is mounted on a plate (24) which is clamped between the end cover (14) and the housing (12) so that the canister (16) is received within the housing (12).  A circuitous passage (78) communicates an inlet port (76) with a sump cavity (68) which is communicated with the canister (16).  Heat is transferred from the gas to the walls of the passage (78) as the gas passes therethrough.  The passage (78) cants toward the sump (68) so that moisture tends to drain into the latter.  A dump valve (110) periodically communicates the sump cavity (68) with atmosphere to thereby regenerate the desiccant in the canister (16) and to void the contaminants from the sump cavity (68).

Abstract: ABSTRACT OF THE DISCLOSURE     A roller for heat- and/or solvent-treatment of fibrous materials has circumferentially extending annuli or spirally arranged rows of coherent or discrete neighboring protrusions each of which has a larger frustopyramidal section nearer to and a smaller frustopyramidal section more distant from the peripheral surface of the cylindrical body of the roller.  The taper of facets of the smaller frustopyramidal sections is less pronounced than the taper of the facets of the larger sections, and the distance between the bases of two neighboring larger sections is less than half the height of a protrusion.  The top lands of the smaller sections are relatively large and, due to the less pronounced taper of the facets of such smaller sections, the top lands can be reground a large number of times without unduly increasing their areas so that the rate of transfer of heat from the cylindrical body to the top lands and thence to the adjacent fibers is not unduly affected by repeated grinding.  The height of the smaller sections is less than the height of the larger sections.  This also promotes satisfactory transfer of heat from the cylindrical body, through the larger sections and to the top lands of the respective smaller sections.

Abstract: SECURITY LOCK    ABSTRACT      A solenoid-operated door lock has a pivotally mounted deadlock lever which can lock either a latchbolt or a deadbolt.  The locking and release movement of the dead-lock lever is controlled by pivoting a release lever which is biased by a spring to maintain the deadlock lever in its selected operating positions.  A solenoid-controlled main operating lever pivots to extend or retract the latchbolt or deadbolt through a lost motion connection.  The lost motion connection ensures that the deadlock lever is moved to its release position before the latchbolt or deadbolt is retracted into the lock.  The lock includes a triggerbolt which is extended when the door is open and is pushed into the lock when the door is closed.  Switches are provided to monitor the operational condition of the lock and the position of the door.  Indicator lights are provided at a remote guard station to show the operational condition of the lock.  A switch is also provided to control the ener-gization current of the solenoid.  A thermal protector operates the solenoid at a reduced current for as long as a dangerously high solenoid temperature is detected. A switch is provided to allow an inmate or a guard to electrically unlock the lock, if the switch is activated by the remote guard station.

Abstract: ABSTRACT Bleaching and Washing Compositions It has been suggested hitherto that the bleaching performance of hydrogen peroxide or persalts developing it in situ at ambient to hand hot (e.g. up to 60°C) temperatures can be enhanced by addition of a transition metal catalyst, but recent investigations revealed that when manganese is selected as catalyst its performance can range from nil enhancement to a substantial improvement.     The present invention is based upon the recognition that manganese catalysis of hydrogen peroxide is promoted by the presence of at least an equimolar amount of calcium, barium or strontium compound, and preferably a molar ratio of at least 50:1.

Abstract: Abstract A vibratory material handling apparatus is provided for mixing of materials, cleaning, blending and/or shake-out of castings or the like.  The machine comprises a horizontal container carried by a frame resiliently mounted on a foundation.  A vibration gener-ator is carried by the container and produces a line of force along an axis which passes exteriorly of the container or intersects with the container but offset from the center of gravity of the container.  The vibra-tion generator is adjustable on the container so that the direction of the line of vibratory force can be changed for changing the tumbling, mixing, cleaning, blending or shake-out characteristics of the machine.  The relative movement between the inside of the container and the material in the container describes angles of attack with the container surface which movements are rotational about a center of rotation.  A line from the center of rotation through the center of gravity of the container intersects the line of force from the vibration generator at a substantially right angle.
