Abstract: A multi-layer angle interlock fabric is woven from warp yarns that extend in straight fashion in a common direction along the length of the fabric and fill yarns which repeatedly extend through the thickness of the fabric along angled paths between opposite broad surfaces of the fabric and interweave within the relatively straight warp yarns. The fabric can be woven using a conventional fly shuttle loom with a programmable Jacquard machine which controls the loom's harness lines to selectively raise and lower the fill yarns extending through a weaving area of the loom as the loom shuttle reciprocates through the weaving area to repeatedly extend a fill yarn across the width of the fabric being formed. Stuffer yarns can be provided by periodically extending the fill yarn across the fabric width betweem adjacent sheets of the warp yarns during weaving.

Abstract: A locking security arrangement is provided for both mounting an electronic component on and locking the component to a bracket assembly. A threaded shaft removably mounted on a tumbler of a lock assesmbly by threaded engagement in an aperture is inserted through a non-circular aperture in the bracket assembly. The shaft is advanced into a threaded aperture in a housing of the electronic component until a non-circular portion of a housing of the lock assembly approaches and then enters the non-circular aperture. A key inserted in the tumbler permits continued rotation of the threaded shaft through rotation of the tumbler relative to the lock assembly housing in response to turning movement of key, to continue advancing the threaded shaft into the threaded aperture in the housing of the electronic component until the non-circular portion of the housing of the lock assembly is completely seated within the non-circular aperture.

Abstract: An inverter adapted to gently invert multi-cell moulds used in a brick making machine includes a first carrier for transporting a mould through a first arcuate path, a second carrier for transporting a mould through a second arcuate path to cause inversion of the mould, and means for transferring a mould from the first to the second carrier. When the inverter is in use, the cumulative effect of transporting a mould through said first and second arcuate paths is to cause inversion of the mould without subjecting the mould to undue shock loads and to accurately locate the mould for subsequent operations thereon. The first and second carriers preferably include pairs of holders rotating synchronously in opposite directions.

The apparatus also includes at least one control tank operatively communicating with the storage tank for supplying at least one controlling element to the raw soy sauce in the storage tank, and a contral mechanism for selectively opening and closing control valves coupled between the control tank and the storage tank according to analytic results from the automatic multiple analyzer thereby to add the controlling element to the raw soy sauce in the storage tank to adjust the concentrations of the at least two ingredients of the prescribed amount of raw soy sauce to target values.

Abstract: In a multi-layer woven fabric in which a first yarn system forms yarn layers between the opposite broad surfaces of the fabric and a second yarn system extends through the fabric thickness between the opposite broad surfaces and is interwoven with the yarn layers, at least one of the first and second yarn systems is comprised of two or more different yarn groups of different material composition disposed within different portions of the thickness of the fabric. This enables different materials such as carbon, ceramics, metals and organics to be disposed uniformly throughout the fabric thickness or to be concentrated within particular portions of the fabric thickness. In this manner multi-layer woven fabrics can be customized for particular applications in terms of their chemical, electrical, thermal, ablative, optical or other properties while retaining the advantageous structural characteristics of such fabrics. Both angle interlock and layer-to-layer weaving configurations may be used.

Abstract: In a plasma gun in which a plasma power source coupled between an anode and a cathode partly disposed within a central plasma chamber within the anode combines with the introduction of inert gas in the region of the cathode to form a plasma arc and a resulting plasma stream flowing from the anode, an improved cooling system is provided for the anode. Cooling fluid in the form of water from a booster pump is introduced generally tangentially into an annular cooling chamber formed between a cylindrical outer surface of the anode and a housing in which the anode is mounted. A helical groove formed by a set of threads in the outer cylindrical surface of the anode provides a spiral flow path for the cooling water within the annular cooling chamber such that the cooling water advances axially along the length of the anode as it flows around the outside of the anode.

Abstract: In a magnetic disk storage system, a hinged separator element having a plurality of angled surfaces is movable between first and second positions. In the first position, the disk storage system is in an operational state with magnetic transducers loaded onto the surfaces of rigid magnetic disks and a carriage which mounts cantilevered beams for the transducers being free to move radially relative to the disks. In the second position, carriage motion is inhibited by the separator element which engages the cantilevered beams to raise the transducers away from the surfaces of the disks and into unloaded positions. A spring loaded trigger member which normally engages the separator element to latch the separator element in either of the first and second positions is momentarily disengaged from the separator element to permit movement of the separator element from the first to the second position by the spring or from the second to the first positions in response to movement of the carriage.

The system includes a device disposed downstream of the stretching device for severing the fan-shaped resin sheet on cutting edges, and a feeding device disposed downstream of the severing device for feeding the product to a prescribed area.

Abstract: Metal particles in powdered form are cleaned of oxides by a method in which the particles are introduced into a plasma stream in the presence of a continuous negative transfer arc. Ionization of a gas within a plasma gun produces a plasma stream into which the metal particles are introduced at a location within the plasma gun. A negative transfer arc power source is continuously coupled between the plasma gun and a cathode downstream of the plasma gun and within the plasma stream to remove oxide coatings from the metal particles as they travel along the plasma stream to either a receptacle located downstream from the cathode or to a substrate which forms the cathode and onto which a relatively oxide-free coating is formed by the metal particles. Such methods of oxide removal are particularly effective with highly oxidizable refractory materials such as titanium, tantalum and aluminum.

Abstract: In a printer in which drive transistors coupled to hammer drive coils control energization of the coils within each of a plurality of magnetic print hammer actuators to provide firing of hammer springs associated with the print hammer actuators, leakage of one or more of the drive transistors when they are switched off is detected by a testing circuit which flags a fault condition to turn off the driver circuits if the current at a junction common to all of the drive transistors exceeds a predetermined threshold value. This provides an early warning system in which faulty transistors are routinely detected well before they have a chance to fail and thereafter burn out the associated coil included within a hammerbank of the printer.

Abstract: A high thermal efficiency multi-wall heat exchange tube is sealed at one end and has the gap between the tube walls filled with a silicon liquid oil that is nontoxic, has a boiling point above that of water, and increases heat transfer efficiency between the inner and outer walls of the tube. The liquid oil is inserted into the gap between the tube walls by placing the tube into a fixture which receives ten tubes simultaneously, heating the tube and the oil, evacuating the gap and inserting oil into the evacuated gap. The fixture includes a manifold connector assembly which is sealingly positioned over the open end of the one or more tubes to provide a manifold connection between the gap of each tube being filled and a source of vacuum as well as a source of oil and a drain. A hydraulic ram facilitates connection and removal of the manifold connector assembly.

Abstract: A tube and shell type heat exchanger providing multi-pass contraflow of two heat exchange fluids includes a cylindrical outer shell, a modular baffle assembly guiding a shell fluid, a plurality of multi-wall tube sets and a pair of opposed end assemblies. A fixed end assembly fixedly receives one end of the tube sets and provides manifolding for directing multi-pass tube fluid flow through the tube sets. An opposite, floating end assembly slidably receives and seals floating tube ends to accommodate temperature induced expansion and contraction. The floating end assembly also provides manifolding for directing the multi-pass tube fluid flow through the tube sets. A triple wall tube set may be employed to provide extra protection against contamination of heat exchange fluids.

Abstract: This invention relates to a cutting mechanism and its method of operation in "cutting side-lock" portions from "green state" roofing tiles. The tiles are manufactured in a conventional concrete roofing tile making plant in which mortar fed to a hopper extruder (18) of conventional design is formed as a continuous ribbon (26) on a series of pallets (P) conveyed beneath the hopper extruder (18). The ribbon (26) is thereafter cut by a knife (3) into discrete tiles (T) on said pallets (P) with a "side-lock" portion of each tile being blanked out by extension portions (32) (34) of the knife (30). The blanked out portions are thereafter removed from the remainder of the tiles by a blade 90 of removal means 14 such that no damage is caused to the tiles (T) and little or not detritus remains on the tile or the conveyors of the tile making plant.

Abstract: In a printer in which an elongated shuttle is driven in reciprocating fashion across a print paper with hammers mounted along the length of the shuttle being selectively fired to print dots on the paper, a timing system provides hammer fire pulses denoting the positions of the shuttle at which hammer firing should be initiated to print in the proper dot positions. Proper timing is maintained so as to allow for printing during acceleration and deceleration as well as during constant velocity movement of the shuttle by determining the average shuttle velocity between each successive pair of fence post pulses generated by a shuttle-coupled encoder. The average velocities are represented by the time lapses between occurrence of the pairs of fence post pulses which are measured and stored during each startup of the printer as well as each time the nominal operating shuttle velocity is changed as part of a change in printer operation.
