Patent GB-2107969-A (GB)
Title: Water-boiling vessels
Inventor: PHILLIPS RICHARD A
IPC: A47J27/21
Filed: 1981-10-23
Abstract: An electrically heated water boiling vessel, such as an electric kettle 1, is provided with a whistle or like steam-powered audible-indication generating means, not shown, and also has an associated automatic cut- out for interrupting the electrical supply to the heating element when the water in the vessel boils, the cut- out switch including a temperature sensitive switch operating element which is arranged to be exposed to steam vented or ducted from the vessel interior when the vessel boils. The problem arises that the venting or ducting of steam to the switch operating element 6 reduces the steam pressure available for operating the whistle, and to overcome this a flap-valve 8 is provided in the vent or duct 3 leading to the switch operating element, the valve being normally closed and opening only when the steam pressure within the vessel has risen to such an extent as to obtain useful operation of the whistle. Alternatively a spring or gravity- loaded ball or poppet valve may be used. <IMAGE>

Patent GB-2146120-A (GB)
Title: Photoacoustic force sensor
Inventor: COLLIER MARTIN
IPC: G01L11/04
Filed: 1983-10-18
Abstract: A force sensor comprises a body 21 eg of quartz which resonates at a frequency dependent on the force imposed on the crystal. Light pulses on line 3 induce resonance of the body 21 by means of the photo acoustic effect. The resonance causes modulation of light passing from path 4 through the crystal onto path 5. The modulation of the light on path 5 is at a frequency which is the same as the frequency of vibration of the crystal and a feedback path 13, 14, serves to tune the light source 11 to produce light pulses of that frequency. The frequency displayed at 15 is thus representative of the force imposed on the member 21. <IMAGE>

Title: Method of detecting leakage of liquid
Inventor: SUZUKI NOBORU
IPC: G01M3/22
Filed: 1984-01-12
Abstract: A predetermined amount of a diluent which mixes with a liquid leaking out of a liquid inlet of a container to dilute the liquid is poured into a recess formed in the liquid inlet, with the base part defined by a stopper fitted into the liquid inlet. The electrical conductivity of the diluted liquid in the recess is then measured. The leakage of liquid from the liquid inlet is detected by detecting whether the measured value is higher or lower than a predetermined level.

Title: Apparatus for heating water
Inventor: LEWIS ROBERT
IPC: G05D23/19
Filed: 1984-11-08
Abstract: An instantaneous electric water heater has a water duct (1, 3, 5, 7, 10) with a water heater (8) comprising heating elements (11, 12, 13 and 14) of different power outputs which can be switched on and off in different combinations by triacs (15) under the control of a controller (16). In some, integral, settings of the controller one or more heating elements remain powered indefinitely. In other, intermediate, settings of the controller the switch state varies in a predetermined sequence so that the average heat output is different from the heat output that can be achieved when the controller is at any integral setting. With an a.c. supply each change in the switch state is caused to occur at a cross-over point. Numerous different heat outputs can thus be obtained without excessive network disturbance. A thermister (9) measures the temperature of the heated water and supplies information to the controller enabling the water temperature to be maintained constant at a value selected by the user. <IMAGE>

Title: Cast crankshafts
Inventor: STRINGER JOHN HOWARD
IPC: B22D19/00
Filed: 1985-03-19
Abstract: A crankshaft is cast in a mould which contains an insert 3 which forms part of the cast crankshaft. The insert communicates for example by means of passages 3d, 3e with all the bearing surfaces : thus in use of the crankshaft oil can be forced into openings 3e and oil will be fed from openings 3d. The provision of the insert obviates the need for a subsequent operation to drill oil ways. The insert 5 may have cylindrical cavities 3a, 3b to lighten the crankshaft. The passages, which preferably form location points for the insert during the casting operation, are trimmed off and 3d, 3e are closed during casting and are trimmed off and opened during subsequent finishing operations. In use, when the insert is filled with oil and the engine is running, the oil in the cavities 3b will act as an oil pump and reduce the energy required to drive the main oil pump. <IMAGE>
