A constant tension maintaining unit is connected to the winch to maintain relatively constant tension on the cable while the cable is wound off the power winch into the well, and a swab is mounted on the free end of the cable. The swab is operable to lift the fluid out of the well when the cable is wound back onto the power winch. Also included is a means in fluid connection with the well operable to receive the fluid lifted out of the well by the swab. Also provided is a swab bar for use in removing fluid from a well and a device for effecting a seal with the well head.

Abstract: A method of ventilating an air breathing animal at a high frequency. A flow of gas is supplied to the first side of a piston mounted within a housing while the flow of gas out of the housing is restricted to elevate the pressure on the first side of the piston. A flow of gas is also supplied to the second side of the piston, which is connected to an air breathing animal, while the piston is alternately moved back and forth within the housing at a selected frequency, amplitude and period, thereby alternately forcing gas into and drawing gas out of the animal. The flow of gas out of the animal is also restricted to elevate the pressure on the second side of the piston. The flow of gas to the first side of the piston both cools the piston and housing and helps to equalize the pressures on both sides of the piston, helping to insure accurate conversion of the mechanical movement of the piston into a pressure wave in the gas on the second side of the piston.

Abstract: An electromagnetic clutch apparatus for providing a reversible mechanical linkage between a driving motor and its mechanical load and which is particularly well suited for use as part of an electrically actuatable automotive cruise control system. The apparatus is inherently self-disengaging, thereby limiting the maximum mechanical load against which the driving motor may operate. The apparatus is designed to be placed between the final output gear of a gear train and the engine throttle and yet overcomes the problems associated with such a placement because the mechanical torque which the clutch is designed to transmit is not directly related to the electromagnetic force required to keep the clutch engaged.

Abstract: A self-contained, solar powered unit predominately used for watering livestock. Fundamentally, the preferred embodiment of the unit is an integrated combination which utilizes a solar collecting panel to generate electricity for powering a fluid pump that pumps fluid into a reservoir tank. The reservoir tank, further, supplies fluid to an adjoined watering trough for access by livestock. The unit is simple, compact, and thus, highly portable while its operation is economical and requires little maintenance.

Abstract: A liquid concentrate dispensing apparatus having a removable and refillable concentrate tank with sensors connected therewith flush with the inside wall of the tank to facilitate cleaning. The sensors comprise detectors which include an electrically conductive housing, one wall of the housing is substantially flush with the inside wall of the tank. Spring biased detent members on the outside of the tank releasably connect the detectors with the dispensing apparatus when the tank is inserted to a preselected position. The tank is provided with two such sensors, one is located in the sidewall and the other is located in the bottom wall. When the tank is inserted into the dispensing apparatus, the spring biased detent members engage contacts on the apparatus. A current passes between the detectors on the sidewall and bottom wall when both are covered by liquid concentrate.

Abstract: The invention is to an apparatus for applying traction to an immobilized patient undergoing oscillatory therapy. The support means for weights has a portion on an oscillating support platform of the bed and part stationary beyond the oscillating portion with a cable contained partially within a conduit thereinbetween offset from the longitudinal center line of oscillating patient support.

Abstract: An apparatus for pivoting a boom arm in a horizontal plane and for locking the boom arm in a fixed position on one side or another of a moving vehicle. The apparatus comprises a rocker arm with a locking mechanism at each end to engage and lock the boom arm in position in its fully rotated position at either side of the vehicle. The rocker arm is operatively connected to a hydraulic cylinder to pivot the rocker arm in a vertical plane to disengage the locking mechanism from the boom arm. A hydraulic motor has a rotating shaft connected to the boom arm to effect rotation of the boom arm from one side of the vehicle to the other.

Abstract: A desulphurization apparatus and method for natural gas in which red iron oxide is reacted with the sulphur compounds found in natural gas to remove these compounds from the gas. The treating solution is then recycled to regenerate the red iron oxide solution with elemental sulphur formed as a byproduct for removal.

Abstract: A method of determining the orientation of a surveying instrument in a borehole from measurements of the earth's gravitational and magnetic fields wherein the azimuth angle is calculated directly without correcting an apparent azimuth. Those measurements are used to calculate the borehole axial magnetic component at each orientation of the surveying instrument in the borehole, and the borehole axial magnetic component is used, along with those measurements, to directly calculate the proper azimuth angle. In a preferred embodiment, measurements are taken at a plurality of orientations in the borehole and the borehole axial magnetic component is calculated in simultaneous equations and then compared to insure the accuracy of the azimuth computation at each orientation. The orientations are preferably non-colinear.

Abstract: Method and apparatus for applying a flow of insulating material such as silicone to predetermined locations on printed circuit boards to avoid damaging the components on the circuit boards, such as solenoids and buzzers, whose functions will be impaired by the application of such material thereto. The apparatus is comprised of a pump which delivers a flow of insulating material to a manifold, the manifold having a plurality of lengths of flexible tubing attached thereto which serve as nozzles for dispensing the flow of insulating material. A printed circuit board is mounted on a conveyor and the conveyor is advanced until the printed circuit board is under the manifold, at which time the manifold is lowered to place the nozzles in close proximity to the printed circuit board so that the flow of insulating material will be directed to predetermined locations on the printed circuit board. The flexible nozzles are selectively positioned to direct the flow to those predetermined locations.
