Title: Starter circuit for fluoroescent lamps - has separate starter cut-out control and fast response carbon resistance holding bimetallic relay contacts open
IPC: H05B41/04
Filed: 1975-05-15
Abstract: A temperature controlled circuit to switch off the starter current in fluorescent lamp circuits is manufactured as a separate unit that is readily exchanged. The unit is designed to avoid the possibility of too high a current being generated in the pre-heat circuit. The bimetallic replay (5) is coupled to a heating resistor (3). After ignition has occurred the bimetallic relay contacts open to break the starter circuit (19). Immediately this occurs the carbon resistance element (9) experiences a rapid rise in temperature and the bimetallic relay is maintained in the open state. This condition is maintained until either the mains power is switched off or the lamp (29) removed.

Title: Solar energy heater for domestic hot water - has differential thermostat controlling two way valve between pump and collector or bypass
IPC: F24S10/75
Filed: 1975-05-26
Abstract: A tube within the collector is linked to a storage vessel (2) by a return pipe (22). The flow pipe (21) from the vessel goes to a pump (3) which discharges through a two way valve (4) either to the collector or through a bypass (43) into the return (22). The valve is controlled by a differential thermostat (6) so that the water is bypassed when the temp. in the vessel has reached the temp. of the collector. The flow is such that the max. rise in temp. on a single passage through the collector is 1 deg.C. This ensures that energy is transferred very efficiently directly to the water.

Title: Portable radioactive source in shielding housing - can only be exposed when carrying handle not in use
IPC: G21F5/02
Filed: 1975-05-30
Abstract: A portable radioactive device, e.g. for local radiographic inspection, comprises a housing with a carrying handle, containing a shield, and a cylindrical, rotatable block mounted eccentrically in this shield and carrying the radioactive source; the carrying handle is pivotally mounted about an axis above the centre of gravity of the entire device, and the pivoting movement of this handle is geared to the rotational movement of the cylindrical block so that, when the handle is in the raised or carrying position, the radioactive source is in its innermost or shielded position and, when the device is set down and the handle is pivoted downwards through 90 degrees, the cylindrical block rotates to bring the radioactive source into the exposed, unshielded position ready for use. Preferably, the axis of the handle and the axis of the cylindrical block are parallel to each other and are coupled together in a 2:1 gear ratio. For any apparatus in which it is desired to carry around a radioactive source for inspection or other purposes. The arrangement ensures that, whenever the operator picks up the device to move it, the radioactive source is automatically and immediately transferred from the exposed to the shielded position, thus eliminating a risk of the operator or other personnel being subjected to radiation.
