Patent GB-2064229-A (GB)
Title: Improvements in electrical machines
IPC: H02K17/02
Filed: 1980-08-19
Abstract: An alternating current electrical machine construction in which a primary winding is modified to create transient electromagnetic conditions for example by having at least two distinct values of pole pitch so as to improve the power factor. In a linear induction motor (Figure 7a) a first pole-pitch portion (STAL) is followed by a second portion (STAA) of shorter pole-pitch. When an inductively coupled solid secondary passes from first to second portions, secondary currents "memorised" from the first, propulsion, section cause current in the second, recovery section. This current can be of unity or leading power factor. Appropriate winding design permits the operation of the machine using an inverter (LCIA) without making provision for reactive power supply. Part of the machine winding, the recovery section, functions as an asynchronous condenser (ASCA) to cope with the reactive power components (Figure 7b). In a cylindrical machine the winding modification can provide transient creating pole or part-pole windings controlling the quadrature flux component. Uniformly slotted stators are envisaged. <IMAGE>

Title: Control units
IPC: G05D23/19
Filed: 1981-01-13
Abstract: A housed control unit for a central heating system has a digital display device (4), a temperature sensor and an audible signalling device both located behind a grille (6), a power input, a control signal output (e.g. to relays operating a boiler fuel solenoid valve and a water circulating pump, electronic control circuitry including memory and timing circuits, and manual controls such as touch- switches (9). Time- and temperature-dependent control signals are produced at the control output depending on the pre- setting of the unit with the manual controls (9). The display device (4) can display time and temperature and the audible signalling device can give an audible indication of operation of the unit (e.g. when a pre-set temperature is reached). The unit can be wall-mounted in a sinking box remote from a central heating boiler and connected thereto via leads at low voltage. The leads provide a low voltage supply to the unit, and the necessary outputs to the fuel valve and water pump relays. The unit may be coupled to other controls and sensors so as to act e.g. as a door-bell and smoke detector. The circuitry preferably comprises a microprocessor. A knob (5) is coupled to a potentiometer for setting the pump ON/OFF temperature. <IMAGE>
Patent GB-2070813-A (GB)
Title: Timepiece with a device for the control of a stepping motor
IPC: H02P8/02
Filed: 1981-02-10
Abstract: The timepiece includes a detector of the direction of the current in the winding of the motor which is used to detect the first reversal in current direction after the end of the driving pulse and to deliver a signal which is representative of this current direction. A comparator circuit (34-36, 38, 39, 48) is used to compare the moment of the appearance of this signal with a reference time which is fixed in relation to the driving pulse and to control a circuit (28-31, 33, 40, 44, 51, 46, 47) which controls the duration of the driving pulses in such a way that the instant at which the signal appears coincides with the reference time. This enables minimum energy to be imparted to the motor for a given variable load.
