摘要： Apparatus for moving a trailer comprising a pair of drive units (10,11) which are mounted or mountable on a trailer and comprise drive motors (20) having friction rollers (22) movable into and out of driving engagement with the respective wheels, the apparatus having a control system for controlling the operation of the drive units (10,11) which is operable to cause any selected one of the drive units to operate in steps interrupted by periods of braking each followed by a period of no operation of the unit. The driving and braking periods are shorter than period of no operation. The control system is also operable to cause the drive units to operate at different speeds.

摘要： An electrically operable actuator (50) suitable for actuating a water flow control valve (10) of a hot water central heating system has a hollow body (54) containing an arrangement of bimetallic discs (55,56) enclosing an electrical heating element (59). The bimetallic disc arrangement carries a movable abutment (63) engageable with an actuating member (53) of a radiator water flow control valve housed within a valve body (51) which is connected by a screw threaded collar to the actuator body (54). The actuator is remotely controllable by passing a current through the heating element (59) causing the bimetallic discs to flex against a bias spring (57) and displace the abutment (63) to operate the actuating member (53) and alter the setting of the flow control valve.

摘要： The birdbath comprises a body (1) adapted to float on water, for example in a pond. The birdbath is designed to become unstable if a heavy bird or other animal attempts to stand on it thereby protecting small birds bathing in the birdbath. The body (1) has holes (6) through which water can flow from the pond to maintain the level of water in the birdbath, and a heater (9) operable to prevent water in the birdbath and also water in the pond beneath the birdbath from freezing. The invention is also applicable to articles designed to provide drinking or/and feeding facilities or/and shelter or protection for birds or amphibians.

摘要： A control system for an electricity distribution circuit which is connected or adapted to be connected to an electrical supply of limited amperage and which, in use, is arranged to distribute electricity from the supply to a number of appliances which are connected permanently to the circuit and/or plugged into sockets in the circuit and which are required to be brought into operation from time to time, the control system comprising means operable, in use, continuously to sense the total current consumption of the circuit and adapted if any one or more appliances is or are brought into operation and as a result causes the total current consumption to exceed a predetermined maximum value, automatically to render at least one appliance inoperative so that the current consumption of the circuit does not remain above said maximum value, and means adapted when at least one appliance has been rendered inoperative by the control system automatically to render such appliance inoperable, such means being operable only by a user to render the said appliance operable.
