Title: Waste-disposal shaft cleaning machine - consists of pressurized disinfectant-container and spray moved up and down by cables and hoists
IPC: E04F17/12
Filed: 1975-06-13
Abstract: The disinfectant container consists of a can inside which is a pressurized gas-bottle. Screwed to the neck of the can is a pin which releases a spring plunger to pierce the top membrane of the gas-bottle. The gas is then released inside the can through a tube and pressurizes the liquid contained in it. The spray in the base of the container consists of a tube opening at the top into the can for the liquid to come through a valve. Sprays are situated at the bottom and consist of three cones each with an opening pointing upwards at an angle of 30 deg. A shield forming part of the can's base projects the sprays. The container is suspended by a cable joined to a ring on the top of the priming-device on the container-top. The calbe is supported by a hoist inserted into the shaft.

Title: Multi-element electric water boiler - has fast heating element for part of contents
IPC: F24H1/20
Filed: 1975-06-25
Abstract: An electric immersion heater water boiler has a main heating element designed to heat up a given proportion of the contents of the water vessel, e.g. between a third and a fifth of the contents, rapidly to a temperature of 60 deg. C, and has another heating element of a lower value to heat the whole of the contents to a temperature of 75 deg. C, followed by a third heating element to maintain the temperature at this value, compensating for heat loses. Each heating element has a thermostat, which when its task has been performed, allows the next element to be switched in, the third element being switched off when the water reaches its maximum temperature. The rapid heating element (R1) is at the top and the other elements in the base.

Title: French telephone network line keyboard adaptor - has circuits to suppress listening control during numbering
IPC: H04M1/31
Filed: 1975-07-23
Abstract: An electrode and electromagnetic u nit is used to adapt a push-buttom keyboard to the French telephone network line with dialling call. The unit only requires four connections and has a circuit to suppress the listening control during numbering and a circuit to rapidly bring numbering to zero on cut-off. The listening control suppression circuit has a reed relay (R1) controlled by logic information from the keyboard (S2). No power is required during numbering.

Title: Semiconductor rectifier module - with gate control and low cut off current, has regenerative and non-regenerative section electrodes on separated surfaces
IPC: H01L29/744
Filed: 1975-09-05
Abstract: Semiconductor rectifier module with gate control, where the high current densities during shut off are eliminated. The semiconductor module (12) has a current regenerating section (50) followed by a non regenerating section (43) and electrodes (42, 30) on separated surfaces (16, 14) of the module. The electrodes provide a current path through each of the sections. The current conductivity of the non generating section is a function of the lateral diffusion of the charge carriers. The length of the non regenerative section in the direction away from the regenerative section is at least equal to the thickness of the section of the module through which the lateral diffusion takes place.

Title: Molecular energy conversion process - uses fan to create air cyclone above liquid in casting with turbine rotor adjacent top
IPC: F01K21/04
Filed: 1976-04-01
Abstract: The energy production process conyerts molecular energy. In a cylindrical casing (1) a negative pressure is created by air turbulence above a liquid (2) at constant level, so as to produce a cyclone. The cyclone energy is then used to drive a power generating machine. The liquid level can be kept constant by regeneration of the cyclone liquid vapour in a closed circuit, or by continuously adding liquid. There can be a cylindrical casing tapering at the top into a chimney (4), a blower (5) generating turbulence, and turbine (3) transforming the turbulence energy, a generator (6), and liquid supply passages (7). The blower can have one or more pairs of blades perpendicular to the surface of the liquid, being driven, via a speed-increasing gear (8), from a motor (9) which can be uncoupled from it.

Title: Domestic water treatment plant delivers three different prods. - viz. for drinking for culinary use and for washing etc.
IPC: C02F9/00
Filed: 1976-05-07
Abstract: Water treatment unit is claimed with a single inlet for supplied water and separate outlet connections for three grades of water treated appropriately for drinking, culinary use and washing/sanitary purposes. The water supply is passed through a common, 10 mu m, filter which has twin outlets. One of these outlets is the supply for the two consumable grades i.e. culinary and drinking and the other for washing water. The consumable grade is directed through an activated carbon filter which delivers the first prod. drinking water. A branch from the activated carbon filter outlet directs water through an ion exchange softener which delivers the second prod., water for culinary use. The second outlet from the common, 10 mu m, filter directs water through a second, ion exchange softener which delivers the third prod., washing/sanitary water. This second softener is in parallel with an adjustable flow, balancing bypass. The two softeners pref. have a common, automatic, regenerating system for their ion exchange resins. The com plete treatment unit is pref. enclosed in a single, plastic casing shaped and sized for convenient installation in domestic kitchens etc. Used for treating water in domestic commercial and industrial situation. Partic. for treating domestic mains water to produce three grades: (1) filtered and purified but not demineralised, water for drinking; (2) filtered, purified and softened water for cooking; and (3) filtered and softened water for clothes washing and dishwashing machines, personal hygiene and sanitary purposes etc. Incoming water is treated automatically in a small packaged unit which delivers grades specially suited to different requirements.
Patent FR-2352907-A1 (FR)
Title: Weft insertion in shuttleless looms with two lances - by transmission from sley to connecting rod energising lances
IPC: D03D49/26
Filed: 1976-05-26
Abstract: A control system for the weft inserters in a straight shuttleless loom with a lance at both sides, has a transmission by belts, chains, or cables, actuated by the sley. This operates a connecting rod via a crank pin, the reciprocating movement of which displaces the lance inserting the weft. The layout of the crank pin is such that lost motion gives a progressive starting up of the lance allowing the reed to retract from the edge of the fabric so as to allow the passage of the lance. Between the end of the connecting rod and the lance a telescopic arrangement may be fitted to double the stroke of the lance for wider fabrics. Replaces the complicated, difficult to maintain and adjust conventional mechanisms by a simple layout actuated by the sley and giving high productivity with practically zero maintenance time.

Title: Optical viewing system preventing light saturation - has differential reduction in path of light to primary sensor via given field of view dependent on illumination intensity
Inventor: WALLER RODNEY WILLIAM
IPC: H04N5/238
Filed: 1977-05-16
Abstract: Optical viewing system has differential reduction in path of light to primary sensor via given field of the view dependent on illumination intensity. The lifht comes from different areas of the field of view. In operation, light from areas in which relatively high-intensive light sources exist is reduced to a greater degree than light which comes from other areas. The matrix reducer comprises a number of individually controlled cells, which consist of liquid crystals, so that their light transmission characteristics change. Thus, the intensity of light on the front plate of the camera tubes is greatly reduced.
