Abstract: A method and apparatus for constructing an articulating pavement comprising the placement in a first layer of a multiplicity of identically shaped foundation units on a subsurface. Each of the foundation units in the first layer is interlocked with adjacent foundation units in the first layer. Overlaid upon the first layer is a second layer of identical foundation units each of the foundation units in the second layer interlocked with adjacent units in the second layer. The units are shaped to create cavities between the first layer and second layer and between adjacent units in the first and second layers. Sufficient cement is then injected through orifices in the units to substantially fill the cavities. The cement is allowed to harden sufficiently to form latch pins which secure the units in an interlocked arrangement and articulatable in both the horizontal and vertical directions.

Abstract: Monosized ceramic particles produced through synergistic combination of monosized latex particles and organometallic reagents in a solvent system. By swelling a poly(vinyltoluene) or other monosized latex with an appropriate organometallic reagent, decomposing the organometallic to ceramic within the latex vehicle, and then removing the latex polymer through thermolysis, monosized ceramic particles are produced. The swelling of the monosized latex particles with the organometallic reagent requires the judicious selection of a solvent system specific to the latex polymer and organic being employed.

Abstract: A storage conveyer for workpieces is movable between selected locations to carry work pieces from one machine to another whilst maintaining the integrity of a batch. An endless chain is wound in a double helix configuration, each helix being supported on a respective driven shaft and an idler shaft. The chain carries pallets for supporting workpieces. The pallets are stepped through a loading location under the control of the manual worker and through a load/unload location where they are accessible to a robot machine, which may be given control of the chain drive. Location is at a lower position and extends out of the helical chain run to provide access for the robot machine.

Abstract: A strategy oriented board game wherein the board is divided into a plurality of elongated slidable strips. A first set of strips have intersections formed by first parallel lines intersecting second parallel lines. A second set of strips have similar intersections relatively offset from the intersections of the first set of strips. When the edges of the strips are aligned, the parallel lines are all connected forming linear intersecting pathways running diagonally across the face of the strips. Each player has a plurality of markers which are placed at home positions at opposite ends of the board. The markers are selectively movable across the strips along the pathways formed by the connection of the parallel lines. The objective is to move a player's marker to the opponent's home positions. According to the rules the strips may be slid, thereby re-positioning the markers located on the slid strip.

The other part comprises an elongate molded plastic housing having channel section which is arranged to hold a female contact between external walls. Notches complementary with toothed parts of the clips are provided such that the two parts of the connector mutually engage in interlocking relationship when mated. The finger serves as a closure for the channel section when the parts are mated.

Abstract: A method and apparatus for producing uniform, monosize ceramic particles forming the microsize particles by vapor condensation or ultrasonic cavitation. Organometallic liquids are directed to an aerosol generator where a droplet stream is projected in free flight within a reaction chamber and a particle sorter. Through the process of sorting the droplets according to their velocity in flight, monosize droplets are collected. The particles may be reacted prior to or after sorting and collection to form the monosize ceramic particle of interest. Sintering aids are introduced into the process to produce ceramic particles capable of improved green body formation.

Abstract: An improved method for amine regeneration wherein a rich amine out of a first heat exchanger is temperature controlled prior to transfer to a second heat exchanger. At least a portion of the hot overhead gasses exiting from a stripping still are transferred to the second heat exchanger. Temperature controlled heated rich amine liquid passes through the second exchanger and contacts the hot overhead gasses. The rich amine liquid is increased in higher temperature thereby and then is transferred to yet a third exchanger and finally to the stripping still for regeneration of lean amine. The reduced temperature overhead gasses are transferred to the reflux condensor for final cooling.

A multiplicity of digit ringlets on the top side of the sheath at the distal end opposite the wrist end are adapted to receive the fingers and thumb of the user's hand so as to secure the covering to the hand. The underneath or bottom side of the sheath has an arcuated recessed portion with the top of the recessed portion near the wrist end of the sheath so as to expose the palm of the user's hand when the hand is received through the wrist opening and the fingers and thumbs are received into the digit ringlets.

Abstract: As shown in FIG. 3, a connector comprises a body (1) and a plurality of detachable connecting members for connecting the body (1) to a rod or tube, wherein the body (1) is provided with a plurality of threaded apertures (11) for receiving threaded end portions of the connecting members. The connecting members are form-locked to the connector body (1) to prevent relative rotation, by means of a hexagon head solid with the connecting member and received in a corresponding recess (12) in the connector body (1), thus preventing relative rotation between the connector body (1) and connecting member (31). In a preferred form, the connector body (1) is a pentagonal prism having two pairs of adjacent faces (4,5;6,7) at 90.degree. and the remaining three pairs (5,6;7,8;8;4) at 120.degree..

Abstract: A method for producing a stable ceramic composition having a surface with a low friction coefficient and high wear resistance at high operating temperatures. A first deposition of a thin film of a metal ion is made upon the surface of the ceramic composition and then a first ion implantation of at least a portion of the metal ion is made into the near surface region of the composition. The implantation mixes the metal ion and the ceramic composition to form a near surface composite. The near surface composite is then oxidized sufficiently at high oxidizing temperatures to form an oxide gradient layer in the surface of the ceramic composition.

Abstract: A method and apparatus for effecting the gravitational separation of hydrocarbons and water discharged from a production formation of a subterranean well. The well casing is extended downwardly beyond the production zone to a water absorbing zone of the subterranean well. A mixture of hydrocarbons and water flows into the interior of the casing through perforations disposed adjacent the production zone. A fluid collection chamber is provided either exteriorly or interiorly of the casing perforations permitting the hydrocarbons to rise to the top of any water. The water flows downwardly, or is forcibly pumped downwardly to the water absorbing formation and is absorbed in such formation. If the fluid pressure of the formation is not sufficient to force the hydrocarbons to the surface of the well, any conventional pump may be mounted in the well casing to effect the pumping of the separated hydrocarbons to the well surface.

Abstract: An non-lubricated, ringless piston engine without a conventional heat exchange system having a cross-head guide for guiding and restraining the piston within a cylinder of a two-stroke engine. The piston-bore radial clearance gap is maintained during engine operation by means of a capacitance sensor controlling a temperature equilibrium flow system within the piston head and the cylinder jacket. The engine operates at high speeds to minimize horsepower losses due to gas leakage, while benefiting from reduced friction losses resulting from absence of piston rings. Blowing gases are collected and returned to the combustion chamber from a pumping chamber formed beneath the piston and above the cross-head guide.

The shaft is also fastened to a wiper shoe which rotates with the shaft and varies the resistance of the circuit. By interchanging shaft-actuator assemblies, and adding appropriate components to the circuit board, the rotary power control unit may take the form of:a simple rotary control,a rotary control with full-on bypass,a simple push control,a three-way push control, ora tandem push control.

Abstract: Apparatus for dispensing fluids to a plurality of receptacles simultaneously, equally, and without dripping. A distributing device is used that uses a major-minor channel configuration such that all major channels fill with fluid before the minor channels fill and all minor channels fill before water exits the outlet holes in the bottom of the distributor. A stand is included which supports the fluid to be distributed and which is designed to exactly center common communion trays beneath the distributor for filing. A stretchable transfer tube connects the fluid in the container with the distributor and, when pinched shut, causes fluid to be sucked back up the tube and which in conjunction with the pipette action of the outlet holes prevents drippage after filling.
