Abstract: The  improved  gate  driver  circuit  provides  a continuous  gate  current  whenever  there  is  sufficient anode-to-cathode voltage difference across the SCR.  This approach described herein eliminates the need to monitor and reapply SCR gate current after each commutation due to load current distortions.  Previous SCR gate driver designs used a pulse train of gate currents to provide a means of keeping the SCRs turned on.   The pulsed gate control  approach has gaps  in the  SCR's operation and requires significant circuitry that dissipates much more drive energy.     Energy for this improved driver circuit is derived from the SCR anode-to-cathode voltage differential.  This eliminates  the  need  for  individual  power  supplies  to provide  isolated  gate  signals  for each  SCR.   This self-powering   feature   reduces   the   intricacy   of controlling multiple SCRs in multi-phase or unreferenced power  systems.   Flexibility  provided  by  this  method allows high power SCRs to be directly interfaced to a digital processor-type controller.

Title: Method of producing a gaseous, hydrogen peroxide-containing sterilisation fluid
Inventor: ANDERSSON JAN
IPC: A61L2/20
Filed: 1990-11-01
Abstract: A method of producing a gaseous, hydrogen peroxide-containing sterilisation fluid displaying good, uniform sterilisation properties, by vaporisation of liqueform hydrogen peroxide which is injected intermittently in finely-divided form into an air current serving as vaporisation agent which is kept at a constant or but insignificantly varying elevated vaporisation temperature. The even vaporisation temperature of the air current is ensured in that the air, prior to the vaporisation, is heated by heat exchange with a heating element (11) of large mass (thermal capacity) and large heat exchange surface area which is kept at the de- sired elevated temperature by regulated energy supply to the heating element and which, during breaks in vaporisation between the intermittent injection of the liqueform hydrogen peroxide, is heated with the aid of heat stored in the heating element.

IPC: F16F13/08
Filed: 1990-11-23
Abstract: A fluid-filled strut particularly suited for automotive engine torque control applications. The strut includes a frame having a pair of fluid-filled chambers located adjacent opposite ends. Each chamber is defined by juxtaposed recesses in a pair of elastomeric blocks located on opposite sides of the frame. A discrete elongate fluid conduit connects opposite axial ends of each chamber. Attachment plates on opposite sides of the frame are bonded to the elastomeric blocks and are connected together by a connector bolt sleeve that extends across the frame through the fluid-filled chamber. The elastomeric blocks permit the frame to move in alternate axial directions relative to the sleeve, and in response to such motion, fluid in the chamber is displaced in alternate directions through the conduit to effect the desired motion damping. The elastomeric blocks are shaped to provide a desirable controlled snubbing action in both directions.

Abstract: FLEXIBLE SERVICE NETWORK FOR COMPUTER SYSTEMS              ABSTRACT OF THE DISCLOSURE      A service  network  has  several  computer  systems connected together.   A  computer  system  can  either be  a "Service Requestor"  (SR),  a "Service Provider"  (SP), or a hybrid of the two,  a "Service Provider/Requestor"  (SP/R).          Once  the  service  network  is  established,   a  SR  can automatically   detect   problems   with   it s   components (hardware, software, or microcode), build a service request describing the problem, select a SP/R responsible for fixing the problem, and send the service request to that SP/R.  The SP/R responsible for fixing the problem receives the service request,  verifies  that  the  SR  is  entitled  to  receive service,  and checks a solution log to see if it has the solution  for  the  problem.   If  so,  solution  information describing the fix for the problem, accompanied by one or more  software  components,  microcode  components,  hardware parts order,  and/or textual instructions,  is sent down to the SR.  If the responsible SP/R cannot fix the problem, it checks to see if it receives support for this problem from any other SPs or SP/Rs to which it is connected.  If so, it sends the service request on to this SP or SP/R, which may in turn send the service request on to other SPs or SP/Rs until a fix is found.   The SP or SP/R can also perform remote problem detection and determination on a SR.

Title: Compact magnetometer probe and an array of them covering the whole human skull for measurement of magnetic fields arising from the activity of the brain
Inventor: AHONEN ANTTI I
IPC: A61B5/04
Filed: 1991-12-10
Abstract: The invention relates to a sensor element made of thin film components and fiber glass, and a support structure made of fiber glass; when the sensor elements are at-tached to the support structure, a sensor system suitable for magnetoencephalographic measurements is formed.      A substrate containing a planar signal coil and a SQUID is attached on a circuit board made of fiber glass using a spring cut on the edge of the body plate. On the sensor element, there is a small but mechanically stable con-nector or several such connectors (5); when the sensor element is plugged in the receptacles (6) on the support structure (7), the element settles in a well defined orien-tation. The support structure (7) is made of a fiber glass shell following the shape of the bottom (10) dewar ves-sel, adapted to the shape of the head. The receptacles (6) are attached to the glass fiber shell by means of springs (9) made of thin fiber glass plate in such a way that an array covering the whole skull as evenly as possible is formed when the sensor elements are plugged to the re-ceptacles. The spring is cut in a way to enable rotation only around an arbitrary axis in the plane of the spring and a translation only in a direction perpendicular to the plane of the spring. When this support structure is inserted in the dewar, the individual sensor elements lean against the dewar bottom (10) by aid of three feet (11), pressed by springs (9), settling perpendicularly to the normal of the dewar bottom passing through the center of the sensor element.
