Abstract: 5,000 HOUR BLOCKING OSCILLATOR FOR                 AN ELECTROMAGNETIC FUEL PUMP                   Abstract of the Invention An electromagnetic fuel pump embodying a blocking oscillator relatively insensitive to breakdown under overvoltage conditions is disclosed.  The blocking oscillator embodies and overvoltage protection circuit which renders the amplifier in the blocking oscillator portion of the circuit non-conductive during any overvoltage conditions.  As a result, the Darlington amplifier only has to withstand the overvoltage and the probability of current mode failure is significantly reduced.  A filter circuit supressed the generated RFI to levels below industrial and military standards.

Abstract: SUPERCONDUCTING DYNAMOELECTRIC MACHINE      HAVING A LIQUID METAL SHIELD              ABSTRACT OF THE DISCLOSURE         A superconducting synchronous motor or generator which utilizes separate radiation and damper shields around a superconducting field winding on the machine rotor.  The damper shield includes a pair of concentrically disposed cylinders held in radial spaced relationship with each other by pillar type structural members.  A liquid metal fills the space between the concentric cylinders and as the rotor, including the cylinders, is accelerated to its operating speed, the liquid metal likewise will reach synchronous speed as a result of viscous drag between the liquid metal and the cylinder walls.  During operation, the rotor shield-ing function is performed by the electrically conducting liquid metal moving at synchronous speed during steady state operation.  Current generated in the liquid metal shields the superconducting field winding from alternating flux generated in the armature due to phase imbalance and har-monics.  During fault conditions, such as a terminal short circuit, currents are generated in the liquid metal to shield the high armature demagnetizing flux from the super-conducting winding.  These currents in the liquid metal react with the field flux in the air gap to produce body forces in the liquid metal which result in the motion of fluid particles.  Forces moving in a radial direction would tend to establish a pressure gradient in the liquid metal, but since the liquid metal is free to move and the pressure gradient cannot be maintained, flow takes place in the space between cylinders to equalize the pressure in the annulus which contains the liquid metal.  The tangential body forces that applied an oscillating torque on prior art metallic dampers, will result in oscillating circumferential liquid metal flow.  Since the liquid metal transmits forces only by-pressure and shear, large pressure gradients cannot be maintained in the annulus and the external forces on the containment cylinders tend to balance the internal pressure thus eliminating bending stresses encountered in the metal-lic shield.  Also, since circumferential body forces can transmit shear only by viscous forces, the torque reaction is significantly reduced.

Abstract: COMBUSTION METHOD AND APPARATUS     ABSTRACT OF THE DISCLOSURE     Combustion of the carbonaceous fuels such as fuel oil may be carried out advantageously in the presence of an oxidation catalyst body.  Under suitable operating conditions the com-bustion can be effected at high rates of energy release for a catalyst and combustor of a given size, producing an effluent substantially free of pollutants.  However, for a given com-bustor installation it may be desirable at times to utilize a thermal burner, associated with the catalyst arrangement, which is disposed for directing jets of burning gaseous fuel such as natural gas from a multiplicity of points just down-stream of the catalyst.  Thus combustion of the gaseous fuel in such jets is obtained substantially throughout a cross section of the downstream zone through which catalyst efflu-ent passes.  When a fuel-air mixture is being fed to the catalyst simultaneously with such supplying of gaseous fuel, the thermal burner preferably is arranged to effect coalesc-ing of the jets of burning gaseous fuel and intermixing thereof with substantially all of the effluent from the catalyst.  Such intermixing may serve to assist the combustion of any fuel which passes the catalyst without complete combustion during warm-up.

Abstract: OPERATOR CONTROLLED PROGRAMMABLE KEYBOARD APPARATUS     ABSTRACT    A cathode ray tube (CRT) and keyboard display terminal are shown wherein the keyboard/display terminal is operated in accordance with the program routines of a microcontroller which is dedicated to the control of the display keyboard.          The terminal is adapted for connection with the I/O channel of a host data processing system.  The microcontroller includes a read only store (ROS) which includes instruction routines primarily dedicated to the transfer of data between the host processor and the microcontroller.  The micro-controller further includes a random access store which is loadable by the customer during initial program load (IPL) operation to store customer selected program routines for controlling the CRT display and keyboard and for initializ-ing tables in the store which define the customer selected character and symbol set.  The tables in store are utilized to provide data for determining the functions which are to be performed incident to the depression of each key on the keyboard and since these are customer loadable, the functions of the keyboard can be changed by reinitializing the system.          The tables are also utilized to provide data which directs the execution of the various graphic, local function and interrupt functions.  These tables also provide the mechan-ism whereby an operator making use of the keyboard can manually change the functions of each and every key on the keyboard except one key which is dedicated to the func-tion of redefining the functions of other keys.

Abstract: LIQUID CYCLONE PROCESS                Abstract of the Disclosure A process for the recovery of protein from vegetable protein material is disclosed which involves differential settling and separation of protein bodies and cellular debris from the material by hydro cyclone separation.          The process includes the steps of grinding vegetable protein material to a particle size range of less than about 40 microns, preferably less than about 10 microns followed by admixing the ground material with an aqueous suspension medium having a pH of 4.5, separating the protein bodies from the non-proteinaceous material by hydrocyclone separation into underflow and overflow streams, the underflow stream substantially containing intact protein bodies, the overflow stream substantially containing cellular debris and recovering the solids from both streams.  The underflow stream which is separated from the aqueous suspension medium provides protein concentration of at least 68% by weight.  Further processing of the underflow stream by hydro-cyclone separation removes additional soluble salts and carbohydrates to provide protein solids of at least 68 to 82% by weight. The novel process of the instant invention provides for the simultan-eous purification and separation of protein bodies from vegetable proteinaceous material to form a protein concentrate.
