Abstract: ABSTRACT     A spring-loaded suspension system for a power-driven auger or screw anchor suspended from the boom of a digger derrick includes means to cushion shock loads and vibration.  The system is articulately connected to the boom by a linkage which provides a universal pivotal connection between the power drive and the boom.  In one embodiment of the invention the linkage is a spring-loaded telescopic link.  In an alternative embodiment of the invention a torque-transmitting coupling between the output shaft of the power drive and the auger or screw anchor is itself a spring-loaded telescopic link.

Abstract: ABSTRACT            Improvements in and relating to Heat Pump Systems The present invention relates to an improved heat pump system of a heating system which also comprises a utilization circuit.  The heat pump system comprises a generator (2), an absorber (1), a condenser (5) and an evaporator (7), and the utilization circuit for circula-tion of a heat carrier medium comprises heat exchanger means (1a, 5a, 15, 17) for removing thermal energy from the heat pump system.        To supplement the thermal output of the heat pump system, when the utilization circuit requires a greater thermal output than can efficiently be achieved by the heat pump system alone, a supplementary condenser (25) is provided in the generator, the condenser comprising a heat exchanger (25a) in heat exchange with vapour in the generator which can be connected in the utilization circuit by operation of a valve (WV) when additional thermal energy is required.  Opening of the valve (WV) occurs simultaneously with an increase in the energy provided to the generator.

Abstract: ABSTRACT OF THE DISCLOSURE      A  thrust  reducing  apparatus  for  a  progressing cavity pump used in a well and driven by a submersible pump motor.   A piston is mounted to the top of the rotor and located in a bore between the stator and the tubing which extends to the surface.  A bypass passage enables fluid discharged from the pump to flow past the bore and the piston.  An annulus passage extends into the  bore  above  the  piston  for  communicating  fluid pressure in the annulus to the top of the piston.  The lower side of the piston is exposed to discharge fluid pressure from the pump, resulting in a net upward force on the piston.  The piston pulls upwardly on the rotor to reduce the downward thrust on the rotor.

Abstract: In an electrophoretic method, particles are separated by means of electric fields which are transverse to each other, which alternate between respective high and low intensities out of phase with each other at a frequency related to the mass of the particles and which move the particles in an overall direction transverse to the respective directions of the fields. For separating large macromolecules, at least one of the fields preferably has an intensity gradient in a direction transverse to its own. The method makes it possible to: (1) separate particles (molecules) larger in size than those able to be separated with previously known techniques, (2) carry out separation at higher speed and at better resolution than is possible with previously known techniques, and (3) concurrently separate particles which differ greatly in mass (molecular weight). <IMAGE>
