Title: Variable speed ratio pulley drive - has pulley halves with complementary curved faces linked by rigid ring
IPC: F16H15/42
Filed: 1974-04-26
Abstract: In the variable spped drive, the two halves (4, 5) of a pulley on the drive shaft (2) are connected via a rigid ring (18) to the two halves (11, 12) of a pulley on the driven shaft (3). Half of each pulley (5, 12) can slide on its respective drive shaft; the faces of the drive pulley are convex and those of the driven pulley of complementary concave shape. The position of the sliding part of the drive pulley (5) can be selected by a pinion (10) and when the setting is changed, the rigid coupling ring is forced to move sideways and cause a corresponding axial movement of the free half (12) of the driven pulley against the pressure of a spring (17).

Title: Pulse edge coincidence detection cct - for digital data transmission using diphase data sync in PABX telephone system
IPC: H04Q11/04
Filed: 1974-06-06
Abstract: A clock signal is transmitted from the switch to the remote phone with the outgoing data and therefore the timing of received signal depends on the timing of the outgoing data. The invention provides compensation to the outgoing signal and as a consequence only very simple circuitry is involved. A detection circuit comprising an exclusive OR gate and a D-type flip-flop receives the data from the phone and a specially derived strobe pulse which is related to the system clock. When a coincidence is detected, the detection circuit provides an output to invert a clock signal which clocks the outgoing data thus introducing a delay equal to half the period of the clock. The circuit is locked in position to cause the delay unless a further transition coincidence occurs which can only happen under normal circumstances if the length of the line is altered.

Title: Prefabricated structural steel high-capacity garage - platforms raised by lift to store cars in cells
IPC: E04H6/24
Filed: 1974-06-27
Abstract: A collapsible, high-capacity garaging facility entirely made of steel consists of columns and beams with a lift-well (1) in the centre. At the sides of the lift-well are cells (3, 4) and reception areas (5, 6). The car is driven onto a platform in the reception area and the engine switched off. The platform is drawn onto the lift by means of an electro-magnet controlled by a worm screw which is in turn controlled by an electric motor and the lift rises until an empty cell is reached. The platform is then pushed along the rails inside the cell. The entrance to both the reception areas and the lift is protected by a safety screen. The garage is cheap to manufacture, takes up little space and gives greatly increased protection against theft and vandalism.

Title: Abduction of legs of baby of 0 to 5 months - using straps and wooden base, to reduce hip dislocation
IPC: A61G13/12
Filed: 1974-07-03
Abstract: Device for abduction of the legs of a baby of 0-5 months comprises a plywood base covered with polyether foam having a density of 70 g/l., with two side blocks of foam at one end around the head and shoulders, and at the other end stops for the knees and a foam block in which are cut stops for the feet.

Title: High pressure flexible hose - produced continuously from a stationary mandrel
IPC: B29C48/12
Filed: 1974-08-01
Abstract: Reinforced rubber hose of bore >=50 mm and length >100 m has uniform cross section lengthwise but pref. has variations in wall thickness and/or reinforcement distribution which induce twist-free flattening of the hose by external pressure. It is produced on a stationary mandrel having >=1 annular array of support surfaces which allow straight (i. e. non-rotating) haul off with negligible friction of continuously laid up pipe. Mandrel supports pref. comprise rollers rotating parallel to the mandrel axis, or fluid pads, or internal conveyors. An external band may oppose torque generated during haul off. Tube walls may incorporate recesses to accept counterweights for under sea use. Wall section or reinforcement pattern may be changed near the ends to accept coupling or fittings. Esp. for mfr. of hydraulically pressurised hose for ocean bottom laying. Lighter and more corrosion resistant than steel pipes, involves few joints because of continuous lay-up and compact, non-twisting coiling characteristics. Undamages if flattened by pressure during laying, can recover shape and sustain an adequate pressure differential between the core pressure and external hydrostatic forces without requiring excessive wall thickness.

Title: Superheating steam in a nuclear power station circuit - by water from reactor or steam generator circulation stream
IPC: G21D5/12
Filed: 1975-10-03
Abstract: Method of superheating vapour in a circuit of a nuclear power station, contg. a turbine with high and low press. stages, utilises, as heating fluid in the superheater, water under press, at the vaporisation temp., taken directly from the flow of recirculation or circulation water of the reactor or the steam generator. In a free-boiling steam generator heated by primary water under press. from the reactor, the water for superheating is taken from the generator in the recirculation return zone at a suitable level. In a pressurised water reactor using a steam generator of the once-through type incorporating successively an economiser, a vapouriser and a superheater, the water for superheating is taken at the vapouriser inlet. In a boiling-water reactor, the water is taken in the reactor vessel directly and at a suitable level in the recirculation water. The overall power output is increased by ca. 4%, compared to existing installations, because the whole of the steam from the generator is used in the high press. section of the turbine, and the rate of recirculation of water is increased, improving the heat transfer. In addn. the stability is improved and corrosion is reduced due to increase in circulation rate. The water circuit can be used for cooling if necessary; the risk of thermal shock in the generator is reduced and the power of the pumps can be reduced, of the order of 500 kw for a 1000 MW station.

Title: Solar heat collector - including an evacuated glass cylinder opt. contg. inert gas
IPC: F24S10/40
Filed: 1975-12-24
Abstract: An absorbant body in the form of a flattened glass U-tube is housed in a glass cylinder, the width of the U-tube being 20% less than the internal dia. of the cylinder. Liq. or gas is circulated through the U-tube. The upper surface of the absorbant body has a thin film approx. 0.1 mm. thick of heat absorbing material for selective absorption of the sun's rays. On the lower surface of the absorbant body is a metallic reflecting coating. The cylinder surrounding the absorbant body is evacuated and a gas, e.g. SnCl4, having at low heat conductivity, is mixed with the residual gases at a press. of 1 to 10 mm. Hg. This gas can be the vapour given off from a liq. or solid in the cylinder. The base of the cylinder through which the two ends of the U-tube protrude is formed by pressing the heated closed end of the cylinder into a mould that has 2 holes and applying a vacuum to the mould to draw the parts of the base near to the holes into them, thus forming openings for the U-tube legs. Useful for collecting solar energy from the sun. The cell is cheap to produce and has high heat collection potential.

Title: Silo for thermal or physicochemical grain treatments - with platforms made from motor-driven pivoting blades
IPC: F26B17/00
Filed: 1975-12-30
Abstract: Thermal or physicochemical treatments of grain prods., which involve contact with a treatment fluid for a certain time, are effected in a sheet metal, masonry or concrete structure provided with a number of platforms each is formed of a series of blades which pivot around an axis and are actuated together by a motor. The blades are permeable to the treatment fluid and some, or all of them can act as fluidised beds. The treatment fluid introduced through the duct which encircles the appts., and passes through the hopper. After passage through the different platforms it leaves by a similar duct at the top and is evacuated by the fan. When the level probe is no longer covered by the grain, it opens the blades through 90 degrees and the prod. falls into the evacuation hopper. All the other blades are operated in turn and another level probe shuts off the feed when the appts. is full. As all the grains are in contact with the treatment fluid for a sufficient time, each grain separately acquires the desired qualities. It is immaterial whether the material to be treated is dusty or not.
