Abstract: ABSTRACT OF THE DISCLOSURE             A resin pipe joint is formed having a groove on the internal surface thereof adapted for receiving a seal.  The mold for forming the pipe joint includes an external split mold and an internal mold core and sleeve with parts slidable relative to one another so that the elements form a space therebetween for inject-ing resin therein.  Subsequently, while the injected resin is still in an unhardened state, the movable parts are moved to a second position relative to one another thereby providing an annular opening surrounding the resin body formed during the resin injecting step.  A pressurized fluid is jetted through a passage way towards the internal periphery of the resin body to cause said resin body to bulge into the annular space thereby creating the internal groove or external bulge in the resin body.

Abstract: Abstract of the Disclosure A digital processor is disclosed which is adapted for use in the guidance and stabilization of a guided missile.  The digital processor is adapted to store a predetermined macroprogram and to process signals produced by various elements within the missile in accordance with such stored program thereby to produce control signals for the missile's flight control mechanism.  The digital processor includes, in addition to a means for storing the macro-program, a data memory and a microinstruction control memory. This latter memory stores sets of microinstructions, each one of such sets corresponding to one of a number of stored macro-instructions which make up the macroprogram.  A register is pro-vided which is adapted selectively to load an addressed micro-instruction or a digital test word serially applied by means external to the missile.  In such an arrangement the missile's digital processor may be readily checked out through a relatively simple interface mechanism.     Also included in the digital processor is a set of address-able flip/flops adapted to be set or reset by signals both in-ternal to and external to the processor.  The state of an addresse one of the set of flip/flops serves as a condition signal used in the execution of various ones of the microinstructions.     Means are also provided which are adapted to couple the output of the macroprogram storage means to the address inputs of the data memory thereby enabling retrieval of both an instruction from the macroprogram memory and its corresponding operand from the data memory within a single clock pulse interval.     This invention wherein described was made in the course of or under a contract or subcontract thereunder, with the Department of Defense.

Title: Control and protection of brushless synchronous motors
Inventor: HERZOG GORDON W
IPC: H02P25/022
Filed: 1976-04-29
Granted: 1979-12-18
Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for controlling the starting of a three phase, salient pole, synchronous motor employs a signal representing slip frequency obtained from power measuring equipment connected to the motor supply.  It requires no connection to the field coil  or other motor component.          Since this signal can be obtained from power measuring equipment, the starting can be controlled from a location remote from the motor, for example, at the motor control switchgear.  A detector determines when the signal has decreased in frequency to a point representing a rotor speed where the field excitation should be applied and it provides as an output a control signal.  This control signal causes the application of field excitation to the motor. In its broadest sense the apparatus may be used to indicate slip frequency remotely.

Abstract: Abstract A process for controlling the speed of strand sintering machines through utilization of the temperature of collected waste gas as measured in the collector pipe as the controlled variable provides improved response by utilizing as an additional controlled variable the temperature of the waste gases at the windboxes.  Either the average temperature of those waste gases that leave the windboxes at a temperature above approximately 100°C. or the location of the burn-through point as determined from the temperature of the waste gases at the windboxes can be used as the additional variable.  In the lat-ter case, the temperature of the collected waste gases can be used to automatically control the desired variable in a secondary cascade-type control loop in which the location of the burn-through point is the actual value and the travel speed is the regulated quantity.
