Title: Sewage treatment process
Inventor: FLETCHER RONALD B
IPC: C02F1/04
Filed: 1994-05-09
Abstract: ABSTRACT            A waste water treatment system includes a preliminary first stage separator for separating an aqueous phase from other materials.  A pressure vessel sedimentation follows for removing most of the remaining solids from the waste material. The liquid and a minor fraction of the solids then pass on to an evaporation vessel where water vapor is removed, compressed and passed through a condenser inside the evaporator vessel to recycle heat to the evaporator. The condensate then passes through a second heat exchanger that heats the liquid flowing into the evaporator. The effluent water has been purified by the evaporation. The residual solids are heat treated to evaporate residual moisture and to sterilize the solids using a steam-jacketed auger. The resulting solids are used as fertilizer.

Title: Metal matrix alloys
Inventor: DAVIES PETER
IPC: C22C1/10
Filed: 1994-01-20
Abstract: The invention provides a method of making a titanium boride metal matrix alloy, by firing a particulate reaction mixture comprising titanium, matrix material and a source of boron (e.g. boron carbide), under conditions such that the titanium and boron react exothermically to form a dispersion of fine particles (preferably greater than 1 micron and less than 10 microns in size) comprising titanium boride (plus titanium carbide where the source of boron is boron carbide) in a predominantly metal matrix. The titanium and matrix are preferably added as a titanium alloy such as ferrotitanium (e.g. eutectic ferrotitanium) or titanium-aluminium. The reaction conditions are preferably selected so that during the reaction a molten zone moves through the body of the reaction mixture, and the average size of the resulting hard particles is uniform throughout the resulting dispersion.

Title: Radio channel access control
Inventor: REDDEN JAMES POWERS
IPC: H04W48/02
Filed: 1994-11-15
Abstract: A cellular telecommunication system comprised of low-Earth orbiting satellites (12) featuring allocation of communication channels among users in cells (34) is disclosed.  Each subscriber unit (26) is programmed with an embedded class identifier.  During periods when it is desirable to limit acquisition of a satellite (12) to some restricted class or set of classes, such as periods of heavy use, the satellite broadcasts a list of inhibited class identifiers allowing only uninhibited classes access to the communication system.  The method reduces thrashing by allowing access to users on a hierarchy class basis.  The method uses both real time cell loading data and historical cell loading information based on previous experiences and can be programmed to limit access to emergency services in the case of natural disasters.

Title: Thrust producing shoe sole and heel improved stability
Inventor: COLE GEORGE S
IPC: A43B7/32
Filed: 1995-02-07
Abstract: A shoe sole and heel member has a sole portion and a heel portion. Bulges are molded into the heel portion and the metatarsal region of the sole portion defining heel and metatarsal cavities. Passageways between the cavities enable air to move back and forth therebetween.

In one embodiment, a single U-shaped heel cavity communicates with a single metatarsal cavity through a Y-shaped passageway. Rigid stabilizers laterally flank the cavity-defining bulges. In another embodiment the heel cavity has forward and rearward portions interconnected by a narrow channel, the portions respectively communicating through separate passageways with opposite sides of the metatarsal cavity, with oppositely-directed one-way valves in the passageways. In a third embodiment, there are two separate metatarsal cavities and two separate heel cavities respectively intercommunicating through two passageways.

Title: Field ground fault detector and field ground fault relay for detecting ground fault corresponding to dc component extracted from ground fault current
Inventor: TANAKA TOSHIO
IPC: H02P9/30
Filed: 1995-02-24
Abstract: According to a field ground fault detector, a predetermined resistor is connected in series to a predetermined DC voltage. A DC voltage is applied between an N electrode side field circuit of a generator and a ground through the resistor. A voltage applied between terminals of the resistor is input to a low-pass filter. A voltage applied between the N electrode side field circuit and the ground is input to another low-pass filter. Output voltages of the low-pass filters are input to a level ratio determining circuit.      The level ratio determining circuit outputs the determined result of the ground fault to the outside of the field ground fault detector corresponding to these voltages. Thus, even if the DC voltage varies or a higher harmonic voltage takes place in a generator of a thyristor exciting type, it does not affect the detecting sensitivity of the ground fault.

Abstract: " In a sports goal frame for defining the goal area and supporting the goal mesh which retains a ball or puck in the goal area. In this invention the goal frame consists of fabricated components which interlock to form a complete and rigid sports goal frame. The sport goal frame has a mesh tie down made of strapping fastened to the appropriate portion of each section of the goal frame. The mesh tie down allows the goal mesh to be securely fastened to sports goal frame and eliminates the practice of attaching the mesh directly to the sports goal. The sport goal frame has a movable sports goal target system which consist of a frame, mesh tie down, mesh pocket, tension cord and clips, which may be suspended inside the sports goal frame in a multitude of locations in the plane of the goal. The sports goal target system provides an unobstructed positive image of the target, being suspended in front of the goal mesh and between the front goal-posts.

Abstract: A multiple beam array antenna system including a first group of right-handed circularly polarized subarrays and a second group of left-handed circularly polarized subarrays.  Combined signals from the right-handed subarrays are output via low noise amplifiers to a first electromagnetic lens while the outputs of the left-handed circularly polarized subarrays are sent via low noise amplifiers to a second steering electromagnetic lens.  A satellite selection matrix output block allows a user to tap into signals from right-handed circularly polarized satellites, left-handed circularly polarized satellites, and linearly polarized satellites.  A plurality of satellites (e.g. right-handed satellite "A" and linearly polarized satellite "B") may be accessed simultaneously thus allowing the user to utilize both signals at the same time.
