Abstract: FOLDED BAR CURRENT SENSOR             ABSTRACT OF THE DISCLOSURE     A current sensor employs a folded conductor bar having aligned holes therein to generate magnetic fluxes in the holes proportional to a current flowing in the bar.  Each of the two holes has two windings therein wound in opposition to each other but connected for adding their voltages.  Corresponding windings in the two holes are wound in opposition to each other and are connected for adding their voltages.  The windings in each hole are offset from a center line, whereby magnetic fluxes generated by current flowing in the bar induce voltages in the coils but magnetic fluxes from external sources produce voltages which substantially cancel.  A feedback arrangement is disclosed for creating an opposing magnetic flux such that essentially zero magnetic flux is present in the magnetic cores of the windings.  A multi-range current measurement device employs a tapped feedback winding selectively connectable to an output amplifier for producing an output voltage having a range set by the number of turns selected on the tapped feedback winding.

Title: Impact resistant pressure relief valve
Inventor: FAIN JOHN E JR
IPC: F16K17/04

Granted: 1992-09-01
Abstract: IMPACT RESISTANT PRESSURE RELIEF VALVE            ABSTRACT An impact resistant pressure operated relief valve comprising a valve body having an exhaust port and a nozzle assembly having a flow passage which terminates in an opening surrounded by an annular valve seat.  A disc holder in the valve body is slidably disposed between a closed position abuting the valve seat, thus closing the nozzle passage and a second position in which the disc holder is displaced from the valve seat, thus opening the valve port to the nozzle passage.  A compression spring forces the disc holder to the normally closed position.  The lower portion of the disc holder is provided with a valve disc having a facing surface which is adapted to contact the valve seat in the closed position.  The invention further comprises compressible shock absorber means interposed between the disc and the disc holder.  The shock absorber functions to lessen the shock forces involved when the valve disc impacts upon the valve seat at closing.  This permits the use of a narrow valve seat which provides a high unit load on between the disc and the valve seat and achieves a high degree of seat tightness.

Abstract: ABSTRACT OF THE DISCLOSURE The  invention  relates  to  an  apparatus  for detachably connecting two parts.   It has a receiving part     which possesses a housing     .  A lock which has a bevelled entrance      is mounted in the housing     .  A locking pin      having a displacement part       is used for locking or for latching with the lock      ,  which  is  kept  pressed  in  the  locking direction by a rubber ring     .   An unlocking part is mounted on the shaft of the locking pin so  that  the  said  unlocking  part can  slide  in  the direction of movement           .  The locking pin carries a thrust plate     on its end facing away from the displacement part      .  If pressure is exerted on this  thrust  plate,  the  displacement  part initially interlocks with the lock     .  When further pressure is exerted in the direction of movement ,  the unlocking part        forces the  lock apart via the bevelled entrance      and against the spring force of the rubber ring    , at right angles to the direction of movement  . The lock then jams at the displacer contour of the unlocking part      ,  The connection can thus be parted again by pulling the locking pin      out of the receiving part .   In another embodiment, the lock         is held on the locking pin          and the displacement part is held on the housing     .

Title: Method and apparatus for preventing surge in a dynamic compressor
Inventor: STAROSELSKY NAUM
IPC: F04D27/02
Filed: 1989-04-12
Granted: 1991-11-05
Abstract: Abstract A method is disclosed for efficiently protecting dy-namic compressors from surge under changing inlet condi-tions and in response to flow disturbances of varying size and speed.  An antisurge control system based on this disclosed method will compute the relative proximity of the compressor operating point to its surge limit as a multi-variable parameter which is self-compensated for changes in gas composition, inlet temperature and pres-sure, compressor efficiency, guide-vane position, and rotational speed.  A combination of adaptive closed- and open-loop control responses is used to maintain a margin of safety between the operating point and the surge limit.  Both the safety margin and the magnitude of the open-loop response are proportional to the rate at which the operating point approaches the surge limit, thus maximizing process efficiency.
