Abstract: A coreless toilet paper roll is produced by winding toilet paper such that the winding speed in the winding apparatus is faster than the paper feeding speed in the paper feeding-and processing apparatus, during a beginning period and final period of the toilet paper winding step, by leaving the wound toilet paper roll in place, with the winding shaft leaves projecting radially outwardly for a pre-determined time after the winding step, and thereafter, by shrinking the leaves and removing the toilet paper roll from the winding shaft. The toilet paper roll so produced has a roll body made of a wound toilet paper material, wherein a beginning layer thereof is wound tightly, and subsequent turns of paper are gradually softened from a middle layer to an outermost layer, an aperture for receiving a supporting bar of a toilet paper holder formed through the center of the roll, and further, the inner surface of the aperture is smooth without projections.

Abstract: A paper conveying device for overrunning paper from a stop position and then, switching the paper back to stop the paper in a stop position. The driving of a paper conveying section for conveying paper is stopped at the time point where the rear end of the paper reaches the stop position. Thereafter, the amount of overrun of the paper is detected, so that the paper is switched back by the amount. Consequently, the amount of overrun and the amount of switchback of the paper are suppressed to the minimum amounts required. In addition, the stress applied to the paper is reduced, and the paper is set in a short time.

Abstract: A method of producing an electrocast brick or other ceramic shape, and the ceramic shape produced thereby, wherein the electrocast brick or other ceramic shape is cast in a mold which is formed, with a predetermined cavity shape and size, of quartz glass particles; the ceramic material of the ceramic shape may be Al.sub.2 O.sub.3 -ZrO.sub.2 -SiO.sub.2 ceramic, Al.sub.2 O.sub.3 -SiO.sub.2 ceramic or other heat meltable ceramic materials.

Abstract: A paper conveying device overruns a document from a stop position and then, switches the document back so that the end of the document collies with a document abutting member provided in the stop position. At this time, the amount of overrun and the amount of switchback of the document are respectively set to the minimum ones required, to reduce the stress applied to the document, and the most suitable control is carried out even in a special mode (SDF mode) in which the document conveying speed is low. More specifically, at the time of the SDF mode, even if a stop instruction is given at timing T2, timing at which a conveying motor is turned off is delayed by a short time .increment.T. A distance A' from the timing T2 to the time when the conveying motor is completely stopped is detected, and the conveying motor is rotated in the reverse direction by a distance B' equal to the distance A'. The conveying motor is rotated in the reverse direction by position control.

Abstract: A molten fiber material flow is rendered into a plurality of fibers by means of a liquid jet such as water jet in place of a pressurized gas or air. The flow moves downwardly in a vertical direction while the water jet cuts it at an inclined angle. The water jet is formed by a single nozzle or plural nozzles of a flat-jet or round-jet type.

Abstract: A food emulsion casing end-closure, and the method of making it, are disclosed. The end-closure is formed of a twist knot through which an air escape aperture is extended. The twist knot forms part of a wadding which is stuffed into the bore of a shirred casing stick and interference fitted therewith. The wadding acts as a shock absorber for the initial shock of extruded food emulsion and serves as means to enhance the consistency of that initial portion of extruded food emulsion. The twist knot is sufficiently tight that it can serve as a permanent end-closure or it may readily be opened by untwisting. Also provided is a lock means for maintaining the twist knot as such.

Abstract: The shirred casing disclosed is packaged in a plastic tube with the lead end of that tube formed into a combined brake/size means which applies oblique frictional force and variable size control to the food emulsion as it is being extruded into the case; also disclosed are means for permitting gas pressure build-up to be relieved and the gas to escape.

Abstract: A highly versatile, resilient and durable food casing sizing device for regulating the release of unfilled casing from a stuffing horn is specially useful in filling casings having string tied end-closures. The sizing ring provides a high degree of product dimensional uniformity and density. The sizing device which is flexible can also be used for stuffing delicate thin walled casings, such as unreinforced thermoplastic types and collagen casings without damage. The sizing devices are especially useful in relation to the production of smaller code products stuffed in plastic or plastic coated casings.

Abstract: An impeller assembly is disclosed which is arranged to produce linear flow of fluid which prohibits radial flow of that fluid. An impeller is surrounded by a hollow cylindrical section mounted and fixed to the periphery of the impeller blades. The cylindrical section may extend either beyond the leading edges of the impeller blades or beyond the trailing edges of the impeller blades, or both, along the axis of rotation of the impeller assembly.

Abstract: A method of melting metal particles includes the steps of swirling molten metal in a vortex within a crucible, adding metal particles onto the surface of the metal, and submerging the metal particles substantially immediately after the particles have been added onto the surface. Apparatus for carrying out the method includes a mixer having a vertically oriented sleeve secured to the bottom of the crucible, the sleeve supporting a plurality of blades on its outer surface and having a plurality of openings adjacent its bottom. The blades force the metal particles beneath the surface of the metal and create turbulence which ensures rapid melting of the particles. The blades as well as the openings adjacent the bottom of the sleeve break up any agglomerated metal particles. Discharge piping is connected to the bottom of the crucible. A vortex breaker is disposed in the piping to control the vortex in the crucible.

Abstract: A mobile holding furnace having a metering pump is adapted to hold a relatively small quantity of molten metal in a contamination-free condition for dispensing to individual molds. The furnace is provided with insulation and electric heating elements for maintaining the molten metal in a liquid state. The furnace is sealed such that an atmosphere of inert gas can be maintained above the level of molten metal. The furnace is mounted upon wheels for easy transportation from place to place. The furnace is used in conjunction with tracks disposed adjacent individual molds, the tracks permitting the furnace to be locked in place while molten metal is dispensed into the molds.

Abstract: A jacket for an enameled vessel with a lower outlet nozzle is described comprising an upper weld ring welded along the outer circumference of the vessel, and comprising a lower weld ring surrounding the lower outlet nozzle, and also the jacket as such. The upper weld ring is conically tapering to its lower end, and the lower end of the lower weld ring is shaped cylindrically. Therefore, the upper end of the jacket can be easily welded with the outer side of the lower end of the upper weld ring, since the lower end of the jacket can be moved into a proper position along the cylindrical end of the lower weld ring.

Abstract: The invention provides a composite carbon or graphite having desirable properties such as corrosion and wear resistance. The invention combines a graphite substrate with a protective porous zone of silicon carbide. The whole body of graphite plus silicon carbide then is infiltrated with aluminum phosphate. An adhered barrier of silicon carbide, ranging in thickness between 0.015 and 0.050 inch thick is integrated with a graphite stratum to form a very hard surface, resistant to mechanical and chemical wear. The silicon carbide barrier is closely compatible to the graphite substrate, in resistance to thermal shock and in qualities of thermal expansion. In order to improve oxidation resistance further, a new composition was formed by infiltrating aluminum phosphate through the silicon carbide into the graphite to form a single body of composite graphite.
