Title: Apparatus for loading material into a storage compartment
Inventor: SMITH FRED T
IPC: B65F3/20
Filed: 1990-03-13
Abstract: Abstract of the Disclosure An apparatus for loading materials from a hopper into a storage container includes a holding chamber formed in part by a movable first panel which forms the floor of the holding chamber. Communication between the holding chamber and the hopper is opened by withdrawing  the  first  panel,  thereby  allowing materials in the holding chamber to empty into the hopper.  As the first panel is subsequently moved to again close communication between the holding chamber and the hopper, materials in the hopper are expelled by a wall which advances in the hopper as the first panel  moves.    Preferably,  the  first  panel  is repeatedly oscillated or cycled opened and closed within a predetermined time period to efficiently move large volumes of materials from the holding chamber, into the hopper, and out into the associated storage container.

Abstract: W.E. No. 54,965 ABSTRACT OF THE DISCLOSURE           The  present  invention provides   a passive superconducting   sensor   for   quench   detection  in  a superconducting coil.  The  sensor  consists  of  a  first circuit  electrically  connected to two voltage taps of a superconducting   coil.    The    first    circuit    uses nonsuperconducting  components  and  preferably contains a resistive element.   The  first  circuit  is  magnetically coupled  to a second circuit by a hybrid transformer.  The second circuit is superconducting and contains  a  readout coil  and  preferably  a  second  hybrid transformer.  The second hybrid transformer is  magnetically  coupled  to  a sense   coil   which   detects   flux   changes   in   the superconducting coil.  The readout coil is  coupled  to  a readout  device  which  measures  changes  in  the current through the readout coil.  The current in the readout coil can  be  made  a  function  only  of the resistance of the superconducting coil between the voltage  turns  and  thus can be used to detect a quench.

Filed: 1991-02-11
Abstract: ABSTRACT OF THE DISCLOSURE   ACOUSTIC FLOW STIMULATION METHOD AND APPARATUS           Stimulating   fluid   production   in   a producing well without stopping production from the well. This is carried out by running into a producing well on an electric wireline a well stimulating tool sized and adapted for passage through a production tubing and placing the stimulating tool at a depth opposite perforations  in  a  producing  zone  in the well.  The area of the perforations are irradiated with  acoustic  energy  in  the  frequency  range from 5 kilohertz  to  30 kilohertz  for  a  predetermined length of time;  the stimulating tool is moved to a different depth by raising or  lowering  it on the wireline and repeating the irradiations at different depths. The acoustic irradiating steps move fines and decrease the well fluid viscosity in the vicinity of the perforations, thereby increasing fluid production from  the  well.   The  apparatus  used  includes  an elongate tool housing for running in  a cased and perforated well borehole;  an acoustic transducer in the  housing  for  forming  an  acoustic  pulse  for impinging on a formation to loosen fines for removal with  formation  fluid flow;   and a  device  further acting  on  the  formation  fluid  flow  to  reduce viscosity thereof to enable enhanced flow from the formation into the perforations in the well.
