Abstract: The invention relates to an improved, novel method and time saving food processor and process, easily assembled and cleaned, and safely operably for whipping egg whites, or cream, and making butter, in seconds, in which two elements define two flat surfaces disposed and coacting at a right angle with respect to each other in a circular container. One of the flat surfaces is centrally rotated in a horizontal plane in the circular container to centrifugally direct and progressively drive a stream of liquid food products against the other flat surface in the presence of air, at a substantially high speed and with hard impact. The other flat surface continuously redirects the flow radially inwardly to recycle it with a continuous high frequency.

Abstract: A multiple pushbutton permutation lock in which push pins equally retarded frictionally in their movement must be manually moved and held actuated in the right combination and pattern to permit a spring-urged slide bar to slide out of a rotationally located critically limiting slot on a hidden disk before manual actuation of the latch can be accomplished for opening the door of the safe.

Abstract: A jet proportioning and liquid mixing pump system having one or preferably more than one proportioning stages with the first stage operating at a low ratio below 1 to 5 to minimize degradation in which solvent under kinetic flow energy initially mixes with free flowing solute at substantially environmental pressure to prevent vaporization effects upon the solute, and, controlling the desired ultimate ratio with high accuracy by either varying the effective flow area of the solvent flowing under kinetic energy in a final mixing zone, or varying the mixer induced output pressure upon the mixture as it leaves a mixing stage after the kinetic flow energy in the mixture therefor has been converted to pressure flow to maintain a positive pressure upon the solute at the proportioning stages.

Abstract: A low cost liquid proportioning and mixing device of high accuracy dispensing a solution or mixture involving volume, pressure and flow rates and including a multi-stage jet proportioning and mixing device in which any variation occurring in the designed ratio of the mixture is confined essentially to the first proportioning stage operating at a low solution ratio below 1 to 5 with the pressure of free flowing solute entering the zone of confluence for each stage and the pressure of the mixture leaving the zone of confluence being essentially equal and the outflow area of any final discharge opening is possibly less but not greater than the flow area of the conduit opening from the zone of confluence of the final stage with or without a conduit used between them, the final proportion of the solution being the multiplicand of the solution proportion of the individual stages.

Abstract: A portable, preadjustable, knockdown and storable rack construction and system for holds of cargo ships embodying a geometric relation and pin arrangement which can be progressively assembled or dismantled with great time saving by hand or crane, or both, without tools, while loading or unloading unitized cargo crates. All parts are engaged and maintain their assembled engagement under gravity, cargo weight and ship vibration.

Abstract: The method and product comprising protecting picture portraying elements upon paper with one or more coats of a permanent non-water soluble sizing which dries transparent; then covering the face with a cloth bonded thereto by a clear liquid which dries transparent and renders the cloth transparent, resulting in an oil-painting-like effect and providing to the paper and to the picture-portraying elements thereon, the capability of being washed, sewn, treated like fabric as well as being rendered waterproof; then, optionally, the paper backing can be removed by soaking with water to: (1) provide greater flexibility and washability, and a measure of transparency which can be enhanced further by the application to the reverse side of one or more coats of a clear liquid such as sizing or varnish resulting in a stained glass window effect viewable from either side with a direct or reflected illumination or (2) after the paper backing has been removed the opacity originally provided by the paper backing can be resto

Abstract: A solution dispensing proportioner utilizing a varyingly pressurized solvent and a solute having a vagrant negative gauge pressure and a tracer that is detectable in proportion to its concentration. The proportioner aspirates the solute and tracer through a conduit, which may have metering flow valves ahead of the confluence in one embodiment, and then for progressive check of the proportion of the solution after confluence by comparing the light transmissivity of the inflowing solute and the outflowing solution, respectively. The viewing is through windows in close proximity to each other where the relative depths of the flowing streams of solute and solution, as viewed, are substantially inversely proportional to the desired percentage of solute in the solution as corrected for a null point traverse by adjusting the solute valve to provide the ratio desired for the solute and solvent in the final solution. The tracer supply is variable to optimize the null point appraisal.

Abstract: A multi-function safety service valve operable both manually and automatically through a toggle fuse-linked joint as located to interconnect the piping of an LP Gas bulk storage tank and a flexible hose connected to fill an LP Gas transport tank on a truck.

Abstract: An inexpensive portable liquid supply tank that serves initially as a shipping container and as a solute or solution dispenser and pump unit carried on a person's back by shoulder straps whose upper support effort is transmitted to the tank about a center of gravity designed to be close to the carrier's back on a strain line directed through its volumetric center of gravity as determined by interbraced semi-flexible front and back walls for carrying comfort and with the straps and a liquid eduction tube extending over the shoulders of the carrier while the other ends of the shoulder straps engage the lower corners of the tank. Motion of the tank on the carrier's back maintains wettable powders in solution if any are present.

Abstract: A unitary supply means for two separate liquids comprising a flexible supply hose unit defining at least two conduits generally of different sizes, one of which preferably is transparent, having an integral common wall reinforcement of extra thickness between them urging the hose to straighten against kinking and providing short free ends for each conduit of different lengths for mating longitudinally spaced series of connections or couplings with appropriate liquid supplies and mixer inlets, the couplings in the solute line being self-tightening under longitudinal stretch strains, and preferably in combination with means for adjusting the relative rates of flow of the liquids through the several mixing chambers.

Abstract: A brush spring and brush housing construction affording maximum operable brush wear without the danger of the brush spring contacting the commutator even if the brush might drop out of the housing. A hook on the brush end of the spring moves against an inclined wall of a tapered slot in the side of the housing and is directed to engage the end of the slot and be restrained from moving or twisting out of interlocking relation with the housing wall as well as being withheld from engagement with the commutator.

Abstract: A high volume filler and automatic fill-limiting valve unit for customer LP Gas dispensing systems in which tandem backflow check valves are opened by incoming replenishing liquid. When a prescribed outage fill level is reached, the inner one of the valves is released from a mechanical restraint of a float control to convert and operate as an inflow check valve which is closed by the incoming flow pressure drop across it to arrest further inflow and permit the outer one of the valves to also close if it is mechanically free to do so. In either case after inflow shutoff the inner valve under spring pressure resumes its normal outflow check valve position to free the float mechanism and independently supplement the backflow check valve function of the outer valve.
