Title: Percussive tool with high pressure fluid jet
Inventor: JAMES BRUCE
IPC: E21B7/18
Filed: 1987-10-05
Granted: 1991-02-05
Abstract: ABSTRACT           In  a  percussive  tool  in  which  a  very  high pressure and preferably cavitating water jet is directed through an opening in the working surface of the tool, the jet is formed by a nozzle positioned in a cavity behind the opening and decoupled from the tool by a bearing layer of water from the jet.  A supply pipe extends rearwardly of  the nozzle  without  contacting  the  tool,  and  is supported externally  of  the tool,  on  a machine which operates the tool,  by a support which allows the fluid bearing to centre the nozzle within the cavity whilst restraining movement of the nozzle axially of the tool.

Abstract: Abstract of the Disclosure An elongate tank for transport or for storage in bulk of semisolid and fluid materials, such as grease and oil.  This tank has an outlet for the material contained therein at one end thereof, and is of generally cylindric internal cross section. It has a generally cylindric piston sized to slide therein, which is adapted to be moved in a direction toward the outlet, thereby forcing the material in the tank through the outlet.  An elastic annular seal is carried in a circumferential channel around the piston adjacent one end of the piston.  The seal is hollow and expandable and has a pressurizing device for varying the pressure within the seal between atmospheric pressure and a pressure higher than atmospheric wherein the seal expands and presses against the internal surface of the tank with the pres-sure such that when the piston slides in the tank the seal is maintained in sliding engagement with the internal surface thereby to wipe the material therefrom and to seal the piston relative to the tank.  The piston is held against canting in the tank by a plurality of pads fastened to the piston and extending radially outwardly therefrom beyond the periphery of the piston for engagement with the internal surface of the tank.  The pads are of low friction material to permit the piston to slide freely in the tank, and they are spaced axially of the piston from the seal a distance sufficient to prevent canting of the piston.

Abstract: ELECTRICAL POWER PROTECTION TECHNIQUE                 Abstract of the Disclosure An electrical power protection technique which is especially suitable for use is three-phase high voltage switch gear applications is disclosed herein. This technique utilizes an electrically insulated housing for each phase of the electrical circuit. Each housing contains a phase intended for placement in circuit with the switch gear and a source of high voltage and has an entry door for gaining access to the fuse from outside the housing. Each fuse is disengagably connected to a power terminal outside the housing through a utility opening in the latter. The terminal  is, in turn, connected in circuit with the source of high voltage and switch gear. A  component interlock assembly is provided for automatically disconnecting each fuse from its terminal and thereafter closing the cooperating utility opening sufficient to physically shield the terminal from its fuse when the entry door is opened. The same interlock assembly automatically opens each utility opening and reconnects its associated fuse with its cooperating terminal when the entry door of its housing is closed

Title: Method of modifying ceramic composite bodies by a carburization process and articles produced thereby
Inventor: CLAAR TERRY D
IPC: C22C29/14
Filed: 1988-12-21
Granted: 1993-05-04
Abstract: ABSTRACT The present invention relates to a novel method of manufacturing a composite body, such as a ZrB2-ZrC-Zr composite body, by utilizing a carburization technique.  Moreover, the invention relates to novel products made according to the process.  The novel process modifies the residual parent metal which remains in a composite body, by exposing said residual metal to a carburizing environment. Thus, by modifying the composition of residual parent metal, the properties of the resultant composite body can also be modified. Parent metals such as zirconium, titanium, and hafnium are well suited to be treated by the carburizing process according to the present invention.

Abstract: Abstract of the Disclosure A method for making a sheet material adapted to be cut into smaller ravel resistant pieces to form portions of a fastener by intersecting (e.g., weaving or knitting) portions of base yarns to form a backing, with at least some of the base yarns being bonding yarns including a first portion formed of a polymeric structural material and a second portion formed of a thermoplastic binding material having a significantly lower melting temperature than the softening temperature of the structural material.  Portions of pile yarns are entwined in the backing with the entwined portions of the pile yarns contacting at least one of the bonding yarns, while other portions of the pile yarn project from the backing to form loops or hooks.  The backing is heated to soften the binding material so that it flows and, upon cooling, adheres to adjacent portions of the yarns, thereby anchoring the pile yarns in the backing.

The electrode  tip  is  then raised and moved to a second location closer to the gripping station at which the electrode tip is again lowered into contact with the overlapped portions of the binding strap such that the latter is again   compressed between the two electrodes.   Upon energization of the electrodes, a second spot-welding operation is performed.   A cutter disposed at the  gripping  station  is  actuated,  so  as  to  sever  the trailing end portion of the binding strap from the residual supply portion of the binding strap, either before or after performance of the second spot-welding operation.  In either case,  the second spot-welding operation is performed under essentially no-load or no-tension conditions.

Abstract: ABSTRACT     A novel packaging system for VLSI circuits allows low-cost construction and maintenance of complex high density high-performance devices with low power requirements. The devices can be individually created by software means from a small selection of standardizable IC chips by disposing a plurality of chips in leadless chip carriers in a mosaic on a substrate, and configuring them by software to selectively communicate with other chips of the mosaic or even to individually change their operating function. The immediate juxtaposition of the chip carriers in the mosaic eliminates transmission line data skew, and also allows considerable savings in chip space and power requirements by dispensing with interconnection drivers, receivers and bonding pads. The chip carrier mosaics may be assembled into modules suitable for plug-in connection to an interconnecting backplane to create even larger devices, and individual modules can be dynamically tested in their high-performance mode by configuring one or more modules as test modules and either plugging them into modules to be tested or making them a permanent part of the device's module array.
