Abstract: ABSTRACT OF THE DISCLOSURE                           VALVE           A valve has a pressure chamber within its housing for remote operation.  A stem in the housing has axial passages for power fluid and for cleaning liquid.  The valve member is a sleeve, biased closed, which engages a movable seat which is resiliently supported.  Leakage around the seals between the sleeve and the stem and between the sleeve and the housing is received in chambers and drained away from the housing to prevent mixing of the cleaning liquid and the processing liquids.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a laminated material for a floating cover for a liquid storage reservoir.  A peripheral envelope formed at least adjacent a portion of the peripheral edges of the floatable cover is adapted to be inflated with a compressible fluid, such as air, for proper tensioning of the cover as the level of the stored liquid varies in the reservoir and for preventing wrinkling of the cover.  The peripheral envelope is adapted to be filled with a non-compressible fluid for pro-viding a ballast for the cover during maintenance operations thereof while the cover is inflatably supported for maintenance of the cover and/or reservoir.  The cover material has a reinforced upper layer and a floatable lower layer which is supported by the liquid.

Abstract: Abstract of the Disclosure A   readily adjustable machine which continuously produces corrugated flexible metal tubing from very light gauge metal and of various diameters.  A warping ring receives there-within a longitudinally corrugated narrow strip of formable metal of light gauge and warps the same helically to produce convolutions by means of a helical warping surface which extends into one of the longitudinally corrugations,  The size of the tube produced can be varied by merely substituting a warping ring of a different size.  A uniquely shaped pair of die-forming rollers have lock-seam forming surfaces which are adjustable relative to each other to provide variation in the degree to which the seam will permit and withstand axial torque.  The lock seam is constructed to be symmetrical about the neutral axis of the corrugation and about the slope line of the common corrugation leg of adjacent convolutions which it constitutes,  The lock is provided by its radially extending deformations in its longitudinal medial portions and terminal portions, with intermediate portions therebetween extending at about 60 degrees thereto.  The terminal portions extend around the bottoms of each of the U-shaped seam elements to further lock them in place,  A flying saw automatically cuts off predetermined lengths of the tubing,  The length of the sections to be cut may be varied by merely repositioning a movable switch in the path of the tube,  The tube has a unique lock-seam which is constructed to withstand greater flexing, greater axial twist and more stress without damage and without opening, and is stronger.

Abstract: ABSTRACT OF THE DISCLOSURE           A low cost postage applicator includes postage printing wheels which can be manually set by thumbwheels accessible through an access opening in a housing.  Encoders provide electrical signals representative of the position of each printing wheel.  The housing is depressed toward a letter or package to be imprinted.  During an initial part of the depression stroke, an inking roller is drawn across the printing wheel face, the access opening is misaligned with the thumbwheels to prevent further setting changes and a contact switch is closed to enable a microcomputer to read and compare the printing wheel settings with the contents of an electronic descending register.  If adequate postage is avail-able and if a letter sensing switch indicates that a letter or package is in place, the microcomputer releases a mechanical interlock to allow the housing to be depressed into a printing position in which the printing wheels contact the letter or package.  A switch is tripped in the printing position to cause the postage applicator registers to be updated by the amount of postage printed.

Abstract: ABSTRACT A process and apparatus are disclosed for the continuous production of polyurethane foam. The invention is directed to the use of a laterally translating mold, the first portion of which has divergent side walls, including a "V"-shaped mold having divergent straight vertical side walls. A polyurethane reaction mixture is deposited at or near the apex of that mold. The deposited mixture can be a partially-expanded preformed fluid mixture formed, for example, by a centrifugal mixing means. Typically, the mixture is permitted to substantially complete its rise after being conveyed past the extremeties of the divergent side walls of the first mold portion. The invention con-templates use of a ratio of conveyor velocity to foam product height lower than those of the prior art. Both rectangular and circular cross sectional products can be produced.

Abstract: Abstract of the Disclosure An elongated treating chamber in the form of a cy-lindrical metallic barrel is rotatable about an inclined longi-tudinal axis.  The food material to be processed is introduced into the inlet or higher end of the barrel through the agency of a rotary valve and is removed or discharged through h nozzle at the other or lower end.  In one embodiment two solenoid-type induction coils encircle longitudinal portions of the barrel, being energized with alternating current power so as to induc-tively heat the barrel.  The heat is induced throughout the thickness of the wall of the barrel and is then transmitted into the food material as the food material passes therethrough.  The temperature of the barrel's outer surface is sensed at two longitudinally spaced locations as the barrel rotates and each of the two induction coils is individually controlled in accor-dance with the temperature that is desired.  The coil nearer the discharge end can be energized with more current than the other coil, thereby permitting the discharge end of the barrel, where there is more food material, to be heated to a greater degree than the inlet end.  In a second embodiment, only one solenoid coil is utilized, and the pitch of the coil turns con-stituting such coil are varied, the turns being closer together at the discharge end where a greater amount of heat is needed than at the inlet end.

Abstract: ABSTRACT OF THE DISCLOSURE         A flame resistant insulated electrical wire and/or cable construction formed by wrapping a wire or cable conductor with a heat resistant flexible refractory tape comprising a porous base fabric, preferably a knit fiberglass fabric that has been coated and impregnated with refractory materials. These refractory materials are bonded to both the surface and interstices of the base fabric by means of a bonding agent, such that the fabric remains flexible and retains its stretch properties.  In the presence of relatively extreme temperature and heat (e.g., above 1750°F.), the bonding agent will decom-pose without flaming, while the refractory materials will fuse into the softened surface of the knit fiberglass base fabric forming a high temperature resistant structure with ceramic qualities and insulative properties.
