Abstract: Disclosed is a water dispensing system for an aircraft wherein hot and cold water supplied to a faucet disposed above a washbasin in a controlled manner including solenoid valves for both the hot and cold water. Two manually operated switches are employed to energize, respectively, the hot and cold solenoid valves. Two different timing cycles are employed. In one timing cycle, when one switch is actuated and then the other switch is actuated within a predetermined time period, both solenoid valves will be turned on to provide approximately equal volumes of water to the faucet for a predetermined time period. In another timing cycle, when one switch is actuated and the other switch is actuated within a predetermined time period, the solenoid valve means energized by the first switch will be turned off and the second solenoid valve will be turned on for a predetermined time period.
Abstract: Disclosed is a test fixture which electrically tests units which have on-grid and off-grid test sites defined by holes. The central feature of this test fixture is the use of an array of flexible test probes which are arranged in an on-grid configuration. Each probe has a conical tip which is inserted into the hole, ahead at the end of a shaft which engages electrical test equipment, and a flexible shaft which connects the head to the tip. A table provides a generally flat surface which is moved in two directions in the same plane, generally at 90.degree. relative to each other. The unit being tested is placed on the surface of the table so that the test sites are presented to the probes and are aligned so that the test sites which are on-grid are in registration with the tips of the test probes. The probes and unit are brought into engagement with each other and the table is actuated. The probes tips slide freely over the surface of the unit being tested and, when they pass a hole, drop into it.
Abstract: Disclosed is a process for treating waste water containing high levels of organic waste products which employs a series of chambers through which the water flows with the upstream chambers promoting anaerobic digestion of the waste products and the downstream chambers promoting aerobic digestion of the waste products. The upstream chambers are charged with a sludge preferably which, because of the conditions maintained within the chamber, has an ash-like characteristic upon being dried and does not contain high levels of water included within it. It is sometimes desirable to recharge the chamber with sludge since this sludge acts as a buffer that can digest shock loads of waste products having a high chemical oxygen demand. The chambers include water circulators which stir the water within the chambers and the downstream chambers having floating on the water surface high surface area media which carries bacteria. Preferably the water flows through the downstream aerobic chamber in a carousel-like fashion.

Abstract: Disclosed is a golf ball holder comprising a generally cylindrical wall element forming a tubular member. There is an elongated aperture running along the entire length of the tubular member between opposed open ends in the tubular member. The tubular member is of a uniform diameter with the opposed open ends having a diameter slightly less than the diameter of the golf balls. The tubular member is made of a resilient material to enable the wall element to expand outwardly when a golf ball is inserted into either of the open ends. The aperture is sufficiently wide to allow the finger of the user to be inserted into it to force a golf ball out of either end but not so wide as to allow a golf ball to be inserted into the tubular member through the aperture. There is a stop member at one of the open ends which prevents a ball from passing through this end unless the user applies pressure to the golf ball and forces it past the stop member.

Abstract: Oil contaminated ground water is purified by immersing one pump into the oil layer in the underground formation and another pump into the water layer in the underground formation and pumping the oil and water into, respectively, an oil storage tank and an oil/water separator. The water being pumped into the oil/water separator contains small amounts of emulsified oil which is separated from the water in the separator and forwarded to the oil storage tank. The water from the separator is passed through a series of filters to remove any trace amounts of oil present in the water so that the oil level in the purified water does not exceed 0.9 parts per billion.
Abstract: A device used to practice putting including a putting station and a remote target station. The putting station comprises a mat on which two parallel rows of posts are provided which straddle parallel strips that serve as guides for the putting head. The number of posts in each row may be the same or different. If there is an unequal number of posts, an entry way and an exit way is provided through which the club head may be moved by the golfer when swinging at the ball. The target station includes a body member having two ramps which lead to a collector section. One ramp serves as an entry ramp and target. The other ramp serves as an exit ramp to allow the ball to move under the force of gravity from the collector section. The collector section includes a lip which acts as a stop to prevent the ball from rolling beyond the target station if it is moving at the desired speed, but will allow the ball to roll over it if it is moving at an excessive speed.
Abstract: Disclosed is an apparatus for circulating water in a body of water including a simulated floating rock structure connected to a pump located remote from the body of water. Conduits place the pump, the body of water, and rock structure in communication so that water is drawn from the body of water and forced under pressure through the conduit connected to the floating rock structure. There is a nozzle element in the floating rock structure centrally located in the top of the floating rock structure connected to the conduit leading from the outlet of the pump so that water under pressure is forced through this nozzle. The conduit connected to the floating rock structure includes a slidable section that automatically increases or decreases the length of the conduit as the water level changes within the body of water. Valves are provided to control the flow of water so that the spray emanating from the nozzle element may be increased or decreased.

This yoke includes a pair of plungers which straddle the wall and engage the floor of the track when the yoke is moved toward the body member. The detent element and plungers resist sliding movement of the fitting in its track. To absorb energy when torque is exerted on the seat, a spherical bearing carries a pin which passes through this bearing member and attaches to the leg of the seat.
Abstract: Disclosed is a mechanism for closing and locking two doors of the cowling of an aircraft engine. This mechanism includes a bolt which is received in a chamber of a receptacle. The bolt is connected to one door and the receptacle is connected to the other door so that, upon closure of the two doors, the bolt slips into the chamber. A cam attached to a rotary member housed within the chamber enables a single mechanic to close the doors and lock them snugly. This cam engages a finger on the bolt upon rotation of the rotary member which draws the bolt into the chamber by pulling against the finger. The cam moves into an over center position which securely locks the bolt in place without locking bolt travel. A locking device is additionally provided for locking the rotatable member in position when the bolt is locked in place. This locking device has a plunger which provides audible signals when the cam is in the fully opened position and when the mechanism is securely locked.
