Abstract: A passive collection and pneumatic lifting system located in a well comprising a pneumatic tube, a fluid tube mounted within the pneumatic tube creating an annulus and a jet barrel chamber formed between the pneumatic tube and fluid tube in fluid communication at the zone to be recovered. A valve in the jet barrel in communication with the jet barrel and the zone to be recovered for allowing passive flow of product to be recovered into the jet barrel for collection therein and for closing upon the introduction of pneumatic fluid pressure by a pneumatic pressure generator to generate pneumatic fluid pressure sufficient to drive the product collected in the jet barrel up hole for recovery. A seal is located below the valve for sealing the product zone in the well from flow except through the valve.

Abstract: The present invention has three essential parts. The first part is a head body comprised of a loop frame and a hosel. The second part is a plurality of horizontal plates set within the loop frame. The third part is a plurality of vertical supports affixed among the horizontal plates so that no part of the vertical supports form the part of the golf ball hitting surface referred to as the club front face.

Abstract: A metal detector system is described for detecting metal objects in a monitoring zone, where the metal detector system comprises: (a) a transmitter coil for generating a magnetic filed in the zone to be monitored, the coil being disposed on a first side of the zone; (b) a first sensing coil disposed on a second side of the zone opposed to the first side, the first sensing coil generating a first sensing signal in response to perturbations in the magnetic field caused by the presence of a metallic object in the zone; (c) a second sensing coil disposed on the second side of the zone, the second sensing coil being spaced apart from the first sensing coil, the second sensing coil generating a second sensing signal in response to perturbations in the magnetic field caused by the presence of a metallic object in the zone; and (d) a sensing circuit for comparing the amplitudes of the first and second sensing signals to generate a difference signal and for generating a first trigger signal for a zero down-crossing of

Abstract: An apparatus for measuring very small flows into and out of large tanks comprising a reference vessel substantially vertical and proximate the tank to be metered and connected in fluid communication with the tank and having transducers located between the connection point and the surface of the fluid in the reference vessel for converting the mass of fluid flow there through to an electrical signal readable into equivalent volume change in the main tank and a meter for reading the electrical signal.
