Title: Stepper motor drive apparatus
Inventor: HAKLUYTT PIERS DAVID
IPC: H02P8/04
Filed: 1986-08-29
Abstract: Drive apparatus, particularly for a twin polygon thermal scanner, utilises a stepper motor 4 driven by pulses of variable width timed, relative to the rotational position of the motor, so that the pulses are substantially centred on the maximum torque position of the motor. This minimizes power consumption. The control circuitry for the motor performs a start sequence, which is aborted and reinitiated in the event that the motor fails properly to start and in which the frequency of the pulses applied to the stepper motor is increased as the motor accelerates. Any excessive increase in the rate of increase of frequency of the pulses is detected and corrected. When the motor is running up to speed, the power applied to the motor is controlled by a phase detector 64 which detects variations in phase between a reference pulse train and a pulse train generated by the rotation of the motor. <IMAGE>

Title: Omni-directional controllers for hacked vehicles and the like
Inventor: FRANKPITT GERALD MARCUS
IPC: B62D11/00
Filed: 1986-09-04
Abstract: An omni-directional controller for a pair of similar power units in the same machine has a rotary ahead/astern synchronous control block 22 which carries, on an axis in the plane of rotation of the block, the pivot post of a differential control element 16 for steering the machine. This element is coupled via Bowden cables 12 symmetrically with respect to the axis of the pivot post 18, to the control mechanisms which govern the outputs of the respective power units. The operating lever 26 of the controller is fixed on the pivot post of the differential control element and resiliently engages a centralising cam 32 on the synchronous control block for basing the differential control element to its neutral or mid position (corresponding to zero steering lock of a vehicle) relative to the synchronous control block 22. Friction discs 40 hold the lever 26 in a set position. Microswitches are mounted in fixed positions relative to the control block so as to detect and signal the zero or mid position of adjustment of the synchronous control block and are connected in an electrical circuit which deenergises the starter circuit for the main engine in all positions of the controller except that in which the control block is in its mid position. <IMAGE>

Title: Friction welding apparatus
Inventor: SEARLE JOHN GILBERT
IPC: B23K20/12
Filed: 1987-12-08
Abstract: In a known method of friction welding two workpieces together, one workpiece is reciprocated relative to the other while the workpieces are pressed together. When sufficient frictional heat has been generated, relative movement is caused to cease and the workpieces become welded. Apparatus for carrying out that method comprises power-driven reciprocatory means (5;5 min ;10;10 min ;9;12;11) which carries the reciprocating workpiece. To balance the reciprocatory means there are counterweights (20;21;27) which move in the opposite direction to the reciprocatory means. Each counterweight is constrained to guide means (98) to move along a rectilinear path. Each counterweight is coupled to the reciprocatory means by reversing means, which comprises a pivoted rocker (14;15;24), first linking means (16;17;25) and second linking means (18;19;28). Each linking means may be constituted by a flexible blade which is anchored in a non-pivotal manner to the reciprocatory means, the rocker or the counterweight, as the case may be.
