Title: Off-peak water heater control
Inventor: COLLINS RODERICK JOHN
IPC: G05D23/19
Filed: 1983-11-24
Abstract: A water heater control switch 30 used for switching a water heater 18 between a normal continuous electricity supply 20,22 and a cheaper off-peak electricity supply 24,26 is such that when the switch is switching back from the normal supply to the off-peak supply, enough time is allowed, after the live contacts 36a, 32a have been opened, before new contact is made, for electric arcs to die away, thus preventing connection between the two separate supply cables. This may be achieved by a cam device in the switching mechanism which is arranged to move the live changeover contact 36a into a stable, centre-off position for a predetermined period, e.g., seconds or minutes, before switching the contact to the off-peak position. <IMAGE>

Title: An electric kettle comprising a temperature limiter
Inventor: COPPIER MICHEL
IPC: A47J27/62
Filed: 1986-12-22
Abstract: The electric kettle comprises a vessel (1), a heating resistor (3) and a temperature limiter (4) for cutting off the electric supply to the resistor when the temperature of the water vapour in the vessel reaches the desired value. The temperature limiter (4) includes a bimetal strip (10) mounted in a chamber (5) communicating with the vessel interior. For water heating, the strip (10) latches a valve (13) in a position leaving a steam inlet (6) open to the chambers (5).

Title: Discharge lamp circuits
Inventor: SAMUELS PHILIP R
IPC: H05B41/04
Filed: 1987-04-22
Abstract: A.C. mains, coupled through a simple filter F to a full wave rectifier bridge B supplies power to an inverter circuit having d.c. input terminals 12, 13, coupled by a bypass capacitor C0. A primary high frequency circuit includes series resonant capacitor C and inductor L components, the capacitor C being in parallel with a primary inductor L1 which, through the resonant inductor L, is in series with a diode D1 that blocks the flow of direct current from the positive rectifier output terminal 12 to the negative terminal 13. To establish the resonant frequency current in the primary circuit, a switch S1 is connected anti-parallel to the diode D1. A drive circuit 14 drives the switch S1 to execute switching cycles at a rate equal to the series resonant frequency of L and C. The high frequency current is propagated in a secondary circuit including a discharge lamp 11 in series with a current limiting capacitor C1, an inductor L1' which is part of an autotransformer formed by L1 and L1', and a further inductor L3 which is inductively coupled to the primary inductor L1 or inductor L so as to cancel harmonics of the resonant frequency of L and C1 the inductor L3 being of a size which with the capacitor C1 is series resonant at an unwanted harmonic of the said resonant frequency. The switch S1 may be a gate turn off thyristor, a gate turn off thyristor in series with a transistor (30), (Figure 10), or an FET (Figure 8). The autotransformer may provide voltage step-up or current step-up (Figure 5) for use with low and high pressure lumps respectively. Alternatively, an isolating transformer may be used (Figure 6), in which case the primary circuit resonance inductor may be provided by leakage reactance of the transformer and the associated resonance capacitor by the capacitive reactance, reflected into the primary circuit via the transformer, of a capacitor & connected in parallel with the secondary L1' (Figure 7). <IMAGE>
