Abstract: COMPRESSOR CONTROL SYSTEM TO IMPROVE TURNDOWN AND REDUCE INCIDENTS OF SURGING                 ABSTRACT OF THE DISCLOSURE A  method  and  apparatus  for  regulating  the operation of a compressor system including a compressor moving a gas from an intake conduit through a discharge conduit to a gas storage reservoir are disclosed.   In accordance with the method, an unload valve in an unload conduit connected to the discharge conduit is initially fully closed and an inlet valve in the intake conduit is initially fully opened.  Then the inlet valve is closed by an amount necessary to maintain the discharge pressure at a design pressure level and at a gas flow rate between the design flow level and a minimum flow level.  When the gas flow rate drops below the minimum flow level, the inlet valve is maintained in its last position and the unload valve is opened by an amount necessary to maintain the discharge pressure below a first pressure level set higher than the design pressure level.   If the unload valve remains open beyond a position set point for longer than a first predetermined period of time, the unload valve is fully opened and the inlet valve is fully closed.  Then if the system pressure drops below a second pressure level lower  than  the  design  pressure,  the  control  steps discussed above are repeated.

Inventor: WATTERS VELMA
IPC: B29C41/38
Filed: 1990-04-25
Abstract: A method for producing a vent-passage for an in-the-ear hearing aid shell.  One or more vent holes are drilled in the shell, and a vent tubing having a copper core is laid against the shell interior wall extending through the vent holes.   Electricity is passed through the core to heat the vent tubing rapidly (e.g. within 15 seconds)  to  60C.    Simultaneously  with  the  heating, acrylic monomer and polymer are mixed.   The mixture is poured  promptly  into  the  shell  over  the  tubing,  and excess mixture is then poured out, after which the coat-ing on the tubing is cured and the tubing is removed.  The rapid heating causes onset of polymerization adjacent the tubing but not elsewhere, so that a very compact vent passage is formed with minimal labour and little excess acrylic polymerization in unwanted areas.   The heating is  performed  using  a  fixture  having  clamping  plates mounted on a rod.  A timer causes clamping of the plates to  hold  the  ends  of  the  core  and  passes  electricity through the core for a  timed period,  after which  the clamping pressure is released.

Title: Low clearance jacking system
Inventor: CARLTON PHILIP M
IPC: B66F5/04
Filed: 1990-05-11
Abstract: ABSTRACT OF THE DISCLOSURE        A hand towable jacking system for hoisting automobiles has a ground frame mounted on castors for ready insertion be-neath a vehicle to be hoisted,  the upwardly moveable load transfer frame being retractable downwardly into telescoped relation with the  ground  frame,  to minimise the clearance height required to accommodate insertion of the system.   A high pressure hydraulic jack accommodates to the low silhou-ette of the system.  A lost motion ramp connection between the hydraulic jack and the load transfer frame permits initial up-ward pivotal displacement of the frame while the jack and its associated load transfer members  are initially in mutually aligned relation, thereby moving the respective members out of alignment,  for continued upward displacement by the jack.  A safety back-up portion of the system provides an inverted U-shaped frame in jamming,  load transfer relation between the load transfer frame and the ground frame.
