Patent GB-2020123-A (GB)
Title: Electrical protective devices
IPC: H02H5/04
Filed: 1979-04-25
Abstract: In order to prevent overheating in electrical connectors (which term includes switches) or components thereof, a temperature sentinel 32 is provided which causes an increased current to be drawn into the connector 13 when a temperature threshold is exceeded. Preferably the sentinel 32 is made from a short length of a dual conductor element having a heat- sensitive insulating material between the two conductors. This material becomes conductive when the temperature threshold is reached, so as to draw more current. This increase in current ensures that conventional over-current protective devices, such as fuses, operate. The use of temperature sentinels operating in the manner described above is described in relation to multi- pin connectors, for electric blankets and hand tools. The invention may be embodied into "no-access" fully moulded plugs. <IMAGE>

Patent GB-2068207-A (GB)
Title: Process for cooking foodstuff
IPC: A23L13/00
Filed: 1980-02-06
Abstract: The process employs a humidity oven in which a product is cooked in the presence of water vapour. The cooking temperature is gradually increased, over the cooking period, until a point is reached at which the whole foodstuff has reached a recognised cooked temperature. The aim is to reduce weight loss in the foodstuff due to cooking. In the preferred method, the cooking temperature is increased in steps, for example, 5 degree steps for intervals of 3 hours each. However, the process may be continuous and automatically controlled so as to maintain a predetermined temperature differential between the inside of a food product in the oven and the actual cooking temperature. The foodstuff may be a pork roll.

Title: Air heating stoves
IPC: F24C1/14
Filed: 1980-09-12
Abstract: A heater having an isolated combustion chamber, and suitable for use in caravans, can be operated in either of two modes. In a first mode, the combustion chamber (11) provides radiant heat to a room space where the heater is disposed, the radiant heat being emitted through a glazed panel (19). Additionally, convective heat is provided by air drawn from the room space through louvres (2), passing behind and around the combustion chamber through a convection duct (20) and deflected forwardly through a collector hood (21) into the room space. In a second mode of operation, the louvres (22) are closed and a fan (25) is operated to force air through a hot air duct (24) to a remote location. This hot air is drawn from a space (17) surrounding the flue, via a downwardly extending narrow passageway (28) surrounding the flue and is also drawn through the collector hood (21) from a region adjacent the glazed panel (19). <IMAGE>
