Abstract: ABSTRACT OF THE DISCLOSURE     An interlock circuit override relay for providing a single energization bypass of an interlock, circuit for each manual actuation of the realy, the r-e-lay being especially useful for bypassing the ignition seat belt interlock circuit employed in late model automobiles. The relay is so designed that closing of its interlock system bypass contacts requires a depression and subsequent release of a manually operated push button in a manner such that the bypass contacts cannot be held closed by taping down the push button. The contacts are held closed by a solenoid controlled latch whose solenoid is energized during energization of the bypass circuit (as during operation of the automobile starter). Deenergization of the bypass circuit restores the contacts to their normal open position. An improved mechanical coupling between n the latch and solenoid armature compensates for minor mechanical misalignment and improves the magnetic field configuration.

Abstract: ABSTRACT OF THE DISCLOSURE        The locking apparatus on a vehicle, etc., for engaging the corner fitting on a container carried thereby includes a shank with a crosshead which is moved into the corner fitting and is rotated ninety degrees to engage the locking device. The shank has an annular rack thereon.  A gear segment engages this rack and is rotated manually to push the rack one way or the other to establish the desired axial position of the shank. On the distal end of the shank is a gear which engages a gear on a rotatable locking member.  The locking member has teeth which engage the teeth of the rack to prevent axial movement of the rack and shank when the crosshead on the shank is in the locked position in the container corner fitting.  The locking member is rotatable to move its teeth away from the rack and that rotation correspondingly rotates the shank.  Ultimately that rotation results in the crosshead on the shank being aligned with the opening in the container corner fitting, whereupon the shank can be moved axially to commence the withdrawal of the crosshead from the corner fitting.

Abstract: A LOGIC CONTROLLED CHARGE TRANSFER DEVICE TRANSVERSAL     FILTER EMPLOYING SIMPLE WEIGHTING                       ABSTRACT OF THE DISCLOSURE A transversal filter structure employing charge transfer techniques which are embodied in charge-coupled-devices although bucket brigade devices may also be used.  In the structure an input analog signal is time sampled and for each sample a sequence of charge packets Q/2, Q/4, Q/8...Q/2n is generated.  Each sequence of charge packets is entered into a serial charge-coupled-device register and each separate charge packet is then entered into a plurality of n parallel charge-coupled-device registers according to the fractional distribution, i.e. Q1/2, Q2/2, Q3/2...Qk/2 in one register, Q1/4, Q2/4, Q3/4...Qk/4 in another register, up to Q1/2n, Q2/2n, Q3/2n...Qk/2n in a last register.  The charge packets in the parallel registers represent the time sampled analog input signal divided by 1, 2, 4, 8,...2n respectively, and tap weights of +1, -1 and 0 are applied by means of logic control and FET switches.  The tap weights are bussed together, summed and differenced and the difference signal is the filter output signal.

Abstract: 25,601 TAR SANDS PROCESS     Abstract of the Disclosure Raw tar sand is treated in a fluidized bed reactor means wherein the raw tar sands are fed into an area below the top of the bed.  the bitumen is converted in the process in a reducing atmosphere including steam to produce hot coked sand and hot off-gases.  Off-gases from the reactor means pass through a heat exchanger means to preheat fresh (raw) tar sand.  The cooled off-gases are separated to recover raw oil, while at least a portion of the separated gases are recycled to the reactor means, to retrieve and retsin heat in the system by passing upwardly through hot spent sand.  Steam and oxygen are injected into the lower area of the fluid bed in an area above the spent sand zone to burn off coked sand so as to produce heat for the cracking zone.

Title: Method and apparatus for electronically commutating a  direct current motor without position sensors

Granted: 1980-07-22
Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus for electronically commutating a direct current motor is disclosed not requiring position sensors but rather sampling induced voltage across an un-energized motor winding to derive control signals therefrom.          One motor winding is energized while the voltage across another winding is sampled and integrated to provide a flux indication. The integrated voltage sample is compared to a reference and when that integrated value exceeds the reference, the next winding of the motor is enabled and the voltage integral returned to an initial value. A ring counter maintains an indication of the currently energized winding and may also be employed to cause the sampling circuit to sample the induced voltage on the winding next in the motor sequence to be energized.  A system for detecting the rest position of a brushless direct current motor is also disclosed wherein a voltage pulse is applied to one armature winding and the voltage induced in another armature winding by that voltage pulse and any associated rotor motion determines the rotor rest position.  To resolve any ambiguous indications, a second armature winding may be similarly pulsed and the results thereof sensed.          An approach for inverting a D.C. voltage for use in ener-gizing an induction motor is also disclosed wherein the normally applied rectangular wave form has its third and fifth harmonic content reduced to more nearly approximate the application of a sinusoidal wave form.
