Title: Electrical stimulation muscle treatment equipment - is portable and is based on single Hartley oscillator with four pole three position switch
IPC: H03K3/80
Filed: 1975-10-03
Abstract: The electrical equipment is intended to be used in the treatment of uscular disorders. The equipment is particularly applicable to exercising muscles which as a result of nerve damage are not being used normally and as a consequence may become atrophied. Both stimulation and exercising sources are based on a common oscillator, the output of which may be rectified to provide pulses of a single polarity. The apparatus is portable and includes control of impulse frequency and level. Control of function is via a four pole three position switch controlling the operation of a basic 20KHz Hartley oscillator (11) using a single NPN transistor.

Title: Rolls of controlled dampness for wiping coated filaments or yarns - for close control of residual coating levels
Inventor: MAZIERES YVES
IPC: D06B15/00
Filed: 1976-07-02
Abstract: Removal of excess coating material from the surface of one or more filaments emerging from a coating bath comprises contacting the filament tangentially with a series of roller surfaces turning counter to the filament movement, so that the rollers remove the excess material progressively. The rollers are continuously wiped, pref. after conditioning to a wet state by turning through a trough of the coating liquid after contacting the filament(s) and before contacting a scraper. The wiping rolls are covered with sleeves of silicone rubber of 40-50 degrees C Shore hardness. The roll wiping blades are made of silicone rubber or of PTFE, mounted on a pivoted or sprung support which can vary the force with which the wiper impinges against the roll. Method is esp. for controlling the amount of bonding agent, e.g. resorcinol-formol latex, applied to silicone resin filaments for e.g. tyre mfr. Various parameters can be adjusted to control the degree of wiping applied to the filament(s), viz roller speed, filament tension, filament speed, filament deflection about the rollers, offering fine control.

Title: Extinguishing fires in instrument rooms using carbon di:oxide - expanding adiabatically before applying, avoiding damage of electronic components through sudden cooling
IPC: A62C3/00
Filed: 1976-08-06
Abstract: A method of extinguishing fires, caused by overheating or short circuiting of an element in an assembly of electronic components in an instrument room, incorporates using liquefied CO2 as a source of gaseous CO2 and expanding the gas adiabatically to 8-12 bars in a receiver, before directing it to an assembly on fire. Condensation of CO2 on electrical and electronic circuits and contraction of components due to sudden cooling are avoided. Such contraction can lead to breakage or change in mechanical characteristics.

Title: Ventilation fan window opening system - has centrifugal weights controlling travel of operating arm to open window slats
IPC: F24F11/00
Filed: 1976-09-13
Abstract: An arrangement for ventilating a room uses the operation of the fan to open a ventilator at the same time, and close it when the fan stops. The drive spindle for the fan blades carries an arrangement of cranked arms mounting centrifugal weights, so that when the baldes and shaft rotate the weights swing out under centrifugal force. This causes a lifting of the ends of the arms attached to a collar, so that this also is lifted so as to tilt the slats of the ventilator. The moving parts can be made of any suitably rigid material. Other types of outlets or windows can be operated by suitable components by the operation of the fan.

Title: Extn. of uranium in situ from its ores - by oxidn. and leaching with oxygen enriched water under carbon di:oxide pressure and alkaline earth (bi)carbonate soln.
Inventor: FLOREANCIG ANTOINE
IPC: C01G43/00
Filed: 1976-12-28
Abstract: Uranium is extracted in situ from the ore deposit (or after ore mining and crushing) by a combination of oxidn. and leaching with O-enriched water under CO2 press. and alkaline earth carbonate or bicarbonate soln. The alkaline earth metals are either Ca or Mg. The CO2 pressure is reduced to 4 bar after the U has been oxidised and dissolved. This pressure is maintained and the CO2 released by the redn. in pressure is recovered for further use. The pressure is finally reduced to atmospheric press. and the soln. degassed by a vacuum treatment. The liq. is then treated with CaOH at pH 10-12 so that Ca uranate and CaCO3 ppte. are formed which are recovered. Process required adaption to the local conditions and there are therefore a number of variations and adjustments required, e.g. to restore the pH of the underground water alkaline earth hydroxide solns. are pumped into the bore holes. The Ca uranate may be treated with H2O2 in order to produce U peroxide which is recovered. The H2O2 treatment may also be used as a second leaching in situ operations. The U may also be recovered by ion exchange. In laboratory experiments a U recovery of up to 92% was obtd. The ore is oxidised in situ to produce a soluble phase, i.e. the method is much less expensive than a mining operation. The former (NH4)2CO3 process for the extn. left NH3 in the underground water and presented a serious pollution hazard. There is no pollution risk involved in the present process, and no ion exchange reaction takes place between Ca2+ and NH3+ ions as in prior art where Ca level of the leaching soln. was increased. When the soln. ascended from underground redn. of hydrostatic pressure caused released of CO2, so that the pH of the soln. increased thus precipitating CaCO3 which clogged the pipes.

Title: Control system for solar heating installation - monitors temperatures at collector, exchanger inlet and storage tank auxiliary heating
IPC: F24D19/10
Filed: 1977-06-06
Abstract: The maximal utilisation of the available heat, at the least expense, as well as the overcoming of the thermal inertia of the plant, are achieved by a system for controlling a solar heating installation. The liquid transporting the heat is pumped round a closed circuit including the collector, a heat exchanger and a storage tank. The heat transporting liquid is only set in motion when the temperature in the collector exceeds that in the storage tank by a predetermined amount. When the temperature in the tank falls below a predetermined value, the auxiliary heater is switched on, and, if it is switched on, as soon as the temperature of the water entering the exchanger is higher than that in the storage tank, the auxiliary heater is switched off.
