Abstract: ABSTRACT OF THE DISCLOSURE      A surge control system for controlling and preventing a surge condition and a method of controlling surge in a fixed or variable speed compressor or a compressor having a variable geometry which provides air to a pneumatic load.  A transducer provides a signal proportional to the outlet pressure of the air from the compressor.  The signal is differentiated with respect to time and if a surge condition is ensuing, the absolute value of the differentiated signal is greater than a reference.   When the differentiated signal is greater than the reference, a portion of the air supplied to the load is vented to reduce the outlet pressure.  A reduction in the outlet pressure alleviates the ensuing surge condition and the absolute value of the differentiated signal decreases, causing the venting valve to close.

Granted: 1982-04-27
Abstract: Abstract of the Disclosure A duplicator for making copies of a microfiche master.          The master is positioned at an exposure station and a supply of copy film stored on a roll is inclemently  advanced by a film drive located between the supply and the exposure station.  During exposure the copy film is biased against the master by an overlying cover.  Cutoff blades located immediately downstream of the exposure station sever each exposed segment of film after it is advanced past the exposure station.  A single motor is used to sequentially advance, sever, and bias the film.  The motor drives a rotatable element.  A Geneva drive coupled to the rotatable element actuates the film drive; cam surfaces on the rotatable element displace a cam follower, the displacement of which is transmitted to a rotatable actuator element.          The actuator element engages the film biasing cover and the cutoff blade.  A tension roller between the roll of film and the film drive maintains the film taut, and upon advancement releases and reengages a brake to allow film to be unwound from the roll.  The master is held at the exposure station on a transparent platen, and registered with respect to the platen by a retaining strip overlying an edge of the platen.

Abstract: TITLE:  FLOW THROUGH PRESSURE REACTION APPARATUS     Abstract of the Disclosure A flow through pressure reaction apparatus that per-mits chemical reactions to take place between fluids maintained under pressure as the component fluids are moved from one loca-tion to another.  The reaction is allowed to take place within an enclosed fluid conduit connected between the discharges of opposed pumps.  Preferably, the pumps are nonpositive displace-ment pumps that will allow reverse flow of fluid through them in response to excess fluid pressure within the conduit.  One pump receives fluid material and forces it through its discharge into the conduit.  A second pump at the opposite end of the con-duit receives the material at its discharge.  The second pump is operated in opposition to the first pump at a pressure head that is lower than the pressure head of the first pump.  A fluid flow can therefore be maintained through the second pump in a direc-tion opposite to the flow it would normally produce.  A pressure equal to the differential of the pressure heads of the two pumps will be maintained within the conduit between the pumps.  The reaction of components within the conduit may cause a situation in which expanding material is forced outward through the dis-charge of one or both pumps without causing an excessive increase of pressure within the conduit.
