Title: An analog electronic timepiece
Inventor: KITANO MASUO
IPC: G04C3/14
Filed: 1983-12-13
Abstract: Circuits are provided for avoiding misdetection of a non-rotated condition after driving the timepiece stepping motor. Voltages induced in the rotor coil by external high frequency magnetic fields, and current produced in the coil by lower frequency AC magnetic fields are detected. When a high frequency or AC magnetic field of sufficient intensity to cause a false indication of motor rotation is detected, the motor is next driven with a pulse having greater width than the normal driving pulse so as to assure operation of the motor. A period is provided, before the normal driving pulse would be applied, to detect AC magnetic fields and a period preceding the period for detection of AC magnetic fields is provided for detection of high frequency magnetic fields. A comparator or inverter is used to determine whether the levels of external magnetic fields are sufficient to cause misdetection of rotor position.

Title: Mechanism for producing differential rotary motion
Inventor: BENSON JOHN ALAN
IPC: B62D9/00
Filed: 1984-03-19
Abstract: The two steerable wheels 12, 13 of a vehicle 10 are associated with respective rotary members interconnected by flexible members e.g. cables. When the wheel 12 is rotated about its steering axis, the wrap of the cables about the associated rotary members will change in a non-uniform manner due to the shape of the rotary members. This will result in the wheel 13 turning in the same sense as wheel 12 but by a different amount. In the maximum lock positions of the two wheels, they will run along the same circular path centered at the mid-point of the fixed wheel axis of the vehicle. This produces a wholly pivotal motion of the vehicle about that point. In Fig 5 the rotary members are "comma" shaped and in Fig 7 cone shaped with the cables riding up and down the cones to vary the effective diameter. <IMAGE>

IPC: A01D43/00
Filed: 1985-04-29
Abstract: A mobile apparatus for collecting and compressing straw comprises a mobile frame and a pick-up mechanism 14 for picking up cut straw. Feed rollers 15 and 16 feed the straw to a chopping mechanism 17 which chops the straw into a predetermined size range, and blows the chopped straw to a holding tank 20 having an upwardly inclined auger 21. Additives are sprayed (from 24) onto the straw leaving the chopping means 17, and mixed by the auger 21. A force-feeding auger 26 feeds the chopped and mixed straw under pressure to a radial extrusion press 27 which extrudes compressed pellets of straw. The pellets are conveyed to a holding tank 33 where they are cooled by a blower 34. The chopped straw from the chopper 17 has a low meal content giving a higher content of chopped straw in the final compressed product, the compression being achieved by the combination of the force-feeding auger 26 and the radial extrusion press 27. <IMAGE>

Title: Active control of unsteady motion phenomena in turbomachinery
Inventor: ACTON ELIZABETH
IPC: F04D27/02
Filed: 1987-04-28
Abstract: A control system actively controls at least one troublesome mode of an unsteady motion phenomenon in turbomachinery in order to enable an increase in the operating range of the turbomachinery. For example, rotor blade flutter or rotating stall may be controlled in a turbocompressor. Surge, forced vibration and acoustic resonance may also be controlled. The control system has a control bandwidth which is at least partly coextensive with the bandwidth of the unsteady motion phenomenon and operates by passing sensor signals related to the unsteady motion phenomenon from a sensor array in the turbomachine to a mode selector/filter which selects those sensor signal components which are related to the troublesome mode. The selected mode signals are amplified and phase-shifted by time-variable amounts so as to produce control signals having controlled amplitude and phase relationship to the troublesome mode. Actuators in an actuator array are continuously driven by the control signals and produce physical effects in the turbomachine which act counter to the troublesome mode without exciting others. Various kinds of actuator for an aircraft gas turbine engine are disclosed, including adjustable vanes and blades, loudspeakers, modulated flow injectors, heat injectors, variable bleed valves, blade shakers and fuel flow modulators.
