Abstract: A mixing valve housing containing two separated inlet chambers and a plurality of valve units which are individually operated from remote positions provides mixed fluid through outlet lines from the individual valve units to destinations remote from the valve housing. An optional flow equalizing apparatus provides balance in the amount of flow from the inlet chambers to each valve unit outlet. All of the valve units in the valve housing have alternative mechanical systems that can be operated using commercial power source or utilize the pressure of the fluid in the inlet chambers for operation. By connecting these mixing valve housings to a pair of centrally located, pressurized headers the need for constant pressure in delivery conduits throughout a structure is eliminated.

Abstract: A process for making a ceramic inlay for filling a cavity in a tooth. A piece of metal foil is pressed into a depression in a jig, where the depression approximates the shape of the cavity; the pressed metal foil is annealed and the pressing and annealing steps are repeated until the foil has a concave depression roughly the same size and shape as the cavity. A ceramic layer is built up on the concave foil to form a ceramic inlay substantially reconstructing the tooth.

Abstract: A high quality projection screen which also is a dry erasable markerboard is disclosed, together with a method for making such a combination projection screen and dry erasable markerboard. The light reflecting writing surface of the combination projection screen and dry erasable markerboard preferably is white, off-white or light in color, and has a bi-directional lenticular embossed surface for increased and more accurate reflection of projected light, and a wider angle effective viewing area. The light reflecting writing surface preferably is made of a thin film of fluoropolymer, such as a modified copolymer of ethylene and tetrafluoroethylene.

Abstract: The sorting plant has two loops (2,102) on which endless cart chains (4,104) circulate. The loops (2,102) extend parallel and adjacent to each other at a transfer station (100). The cart chains (4,104) are driven by synchronized drives (6,106) in such a way that two carts (5,105) move exactly adjacent to each other at the transfer station (100). The second loop (2) is extended along a somewhat lower elevation at this location. By tipping the receptacles (113,114) of a cart (105) on the first loop (102), unit load (10) occupying the same is directly transferred onto the cart (5) of the second loop (2) that moves exactly adjacent to it. This arrangement makes it possible to load one gross distribution facility (101) and two fine distribution facilities (1,1a) in a mail distribution center in a reasonable manner and with small spatial requirements.

Abstract: A container suitable for holding paint incorporating a first open receptacle having integrated therein a paint distribution board for use with a paint roller and a second open receptacle suitable both for holding a paint brush and to serve as a means for pouring liquid from the container. A lid suitable for covering the container.

Abstract: A sorting plant which has a closed rail (3) that forms a loop (2) on which an endless chain (4) of carts is guided. Loading stations (9) for the loading of the carts (5) with piece goods (10), as well as target stations (11) that receive the piece goods (10), are arranged along the rails (3). Each cart (5) has two receptacles (13, 14) that can be individually swiveled about a collective axis and also two separate activation elements to tilt the receptacles (13, 14). Each target station (11) has two cams that can be individually activated to initiate the tilting process. A package (10) is loaded onto the cart (5) at the loading station (9), namely, onto both receptacles (13, 14) of this cart (5) or only one of these receptacles, depending on the size of the package (10). The target station (11) of the occupied receptacle (13, 14), or the occupied receptacles (13, 14 ), are entered into a control device (12).

Abstract: The present invention provides an apparatus for spreading on the ground granular and liquid treatment materials at the selection of the operator. The apparatus includes a motorized cart having granular and liquid storage compartments and associated controls to release the treatment materials on an as needed basis. A spray wand is also provided to permit spraying the liquid material for detail applications. A pump is operably connected to the liquid storage compartment, the spray wand, and one or more area spray nozzles to provide the liquid for spraying purposes. The granular material can be radially broadcast from the granular storage compartment as the cart traverses the ground. Controls for the motor and the granular and liquid treatment operation are mounted to the apparatus for easy access by the operator. The present invention also provides a retrofit package for inclusion on available granular spreaders to provide the motorized granular and liquid treatment apparatus disclosed herein.

Abstract: A cross-draft spray booth is provided with an exhaust system, an air inlet and at least one columnar filtering unit. The columnar filtering unit includes a support frame, an exhaust outlet and a filtering medium in the shape of a column. The columnar filtering unit is preferably cylindrical, and utilizes non-porous filtering material.

Abstract: A display case includes separately formed components: (1) a casing which defines an internal cavity having an open end, and (2) a latching closure device with an integrated living hinge. The two components are made of different plastic materials, wherein the different materials have properties advantageously suited for each component. Preferably, the living hinge and closure device is made of a resilient plastic, while the casing is made of a substantially transparent plastic through which the interior of the casing and its contents can be viewed.

Abstract: The present invention relates to a tandem pneumatic/hydraulic reciprocating cylinder with an integral oil reservoir. The invention may be used to impart reciprocating motion to adjustable apparatus used in the cleaning and polishing of roll assemblies.

Abstract: Flavorings, seasonings, fragrances, skin texturizers, deodorants, and the like, and methods of making such are disclosed. The method includes melting a water soluble carrier material and dispersing an additive within the melt. The dispersed melt is then sprayed into a chilled gas and the resulting powder is recovered.

Abstract: In a fingerprint matching system, a finger platen formed of an optical element having a tacky reading surface for providing an accurate and consistent image of a fingerprint pattern.

Abstract: A method for producing an improved food product comprising the steps of providing an unlayered, substantially-homogeneous mixture of previously popped popcorn and shredded cheese; heating the mixture to melt the cheese; cooling the mixture to form a cohesive mixture of cheese and popcorn; freezing the cohesive mixture to form a frozen mixture; and freeze-drying the frozen structure; and the resulting food product.

Abstract: Microcapsules having a solid, fusible shell and a multiplicity of liquid cores. The microcapsules can be made by spray-cooling a water-in-oil type emulsion. The microcapsules, in aggregate, are a dry, free-flowing powder, and can be heated or otherwise processed to release their contents. The microcapsules can be used in food and non-food applications. The core can be any liquid, preferably aqueous, which does not readily dissolve or disperse the shell.

Abstract: A method of cementing oil well casings and a cementing tool used when performing the method are provided. A novel top cementing plug functions in a conventional manner during proper oil well casing cementing operations, but if inserted into the oil well casing in error, allows cement to be pumped through it. The top plug includes an outer, hard rubber casing having vertically spaced fins formed about its circumference. A central passage is provided through the outer casing and receives a cylindrical, metal sleeve. In one embodiment, a bore is formed in a portion of the metal sleeve to define a shoulder within the sleeve. The bore receives a cylindrical housing which carries a spring loaded, ball valve mechanism. The valve mechanism includes an annular spring retainer which rests on the shoulder. One end of a helical spring within the housing contacts the retainer while the other end of the spring biases a ball against an annular flange at the top of the housing to seal the passage.
