Title: Controlling exothermic reactions in porous materials - by vaporisation of e.g. water, esp. for resin impregnated wood or concrete
IPC: B01J8/02
Filed: 1973-12-12
Abstract: A process is claimed for controlling a exothermic reaction, particularly thermocatalysed, occuring inside a porous medium, e.g. wood or concrete, by including inside the medium a materila (I)(which may normally be part of the medium, e.g. water) in sufficient amt. to vaporise, by absorbing the heat of reaction, the temp inside the medium being limited to the b.pt. of (I) under the pressure conditions of the reaction. The process is particularly claimed for controlling the thermocatalysed polymsn. of a resin, e.g. polyester, or a mixt. of resins impregnated in a porous material, particularly an air-diced wood contg. 14-18% moisture. In prior art such wood had to be dried to a moisture content of 2-6%, prior to impregnating with the resin. The process results in significant saving in energy and minimises the loss of resins by evaporation.

Title: Charge regulator for electric storage heaters - uses calculator to compute charge required on basis of mean external temp. over one day
IPC: G05D23/19
Filed: 1974-05-24
Abstract: The charge regulator is for electrical storage heaters used in domestic, factory and office buildings. An electronic calculator controls charging, on the basis of the mean external temperatures measured during prescribed periods between six 0'clock on succeeding days and on a set base temperature for the building. Positive or negative control signals vary according to whether external temperatures are lower or higher than the building base temperature and hence control the charging of the heaters. Protection against loss of charge due to supply failure is provided and cuts out the supply if the mean external temperature exceeds that of the base or if the charge rate required is low, avoiding constant switching in and out of circuit.

Title: Electronic switching circuit for stepping motor - has power transistor shunted by Zener diode
Inventor: IRISSOU PIERRE-REGIS MARIE HEN
IPC: H02P8/12
Filed: 1974-07-23
Abstract: The switching circuit employs a power transistor (3) with the emitter collector path connected in series with one or more inductive windings (1) energised for rotating the rotor of the stepping motor.
