Title: Rotary speed control for wind powered generator - by vary load circuit resistance with wind force
IPC: F03D7/02
Filed: 1974-07-11
Abstract: An air flow is supported on a tower structure. A system of shafting and gearing connects the fan to the generator. The shafting is extended to take a rotating mass governor, with masses rotating on arms connected to a slide which operates between contacts for minimum speed and for maximum speed with an overspeed setting at which the fan blades would be stopped. The contacts connect with the variator which acts on the electrodes in an electrolysis bath. An increase in speed moves the electrodes apart and increases the resistance of the circuit to the generator thus slowing it down, and slowing down the fan.

Title: Transformer tap changer operating force storage mechanism - has inner shaft linked to operating shaft and outer shaft rotating tap changer assembly
IPC: H01F29/04
Filed: 1974-07-25
Abstract: The operating force storage mechanism for transformer tap changers has two drive shafts, one inside the other. The inner shaft is linked to the shaft which drives the tap changer contacts. The hollow outer shaft is driven by a cog wheel and displaces the tap changer switching assembly by means of an eccentric ring around the linkage between inner shaft and contact operating shaft. The inner shaft flips in alternate directions as the outer shaft rotates and operates the contacts. The storage mechanism is rotated with the tap switching assembly by means of a rim gear as the tap changer is switched from tapping to tapping.

Title: Brick with mortar check partition across frog - forms uniform mortar run for a strong joint
IPC: E04B2/24
Filed: 1974-08-14
Abstract: The brick is constructed with a mortar check by casting a partition inside the frog of a conventional brick. The partition is cast cross-wise across the frog. In a conventional brick, when the mortar does not find any check to the settling of the bricks, it merely disappears into the frog (A). However, in bricks with a partition, when the bricks settle, the mortar is compressed against the partition, transforming it into a uniform bar which gives added strength to the solidity of the completed structure.

Title: Analysis of rock samples - using agitated vessel with built-in filter
Inventor: DURAND BERNARD
IPC: B01L99/00
Filed: 1974-11-08
Abstract: Rock samples are analysed by treating successively with different mineral acids in a falst-bottomed agitated vessel constructed of suitable acid-resisting fluoroplastic. Spent acid may be withdrawn via filter to a neutralising vessel. Used for the analysis of geological samples. Successive treatments may be performed without manipulation of the samples in between treatments. The device si particularly useful in the determination of organic content of samples as it enables the organic material (pollen etc.) to be retained on the filter.

Title: Hawser end clamp for large marine tanker - has swinging jaws to fit over hawser, and enclosing sliding taper block
IPC: B63B21/04
Filed: 1975-07-04
Abstract: A device for gripping the end of large hawsers (29) on tanker ships for mooring purposes is a self-locking clamp mounted each side of the hull. The body of the clamp has a lug (9, 10) each side, attached to chains and cables (33) with their ends looped around bitts (34) on the hull. The hawser is then inserted between jaws (3, 4) of the gripping device by swinging the jaws open, and passed around a winch (32). The jaws are then closed and the clamp is moved towards the winch so that a wedging member between them, curved to match the hawser, grips the hawser. A small amount of the hawser is unwound, to lock the wedge completely on the hawser.
Patent FR-2321638-A1 (FR)
Title: Viscoelastic load suspension system - uses elastic members in mutual opposition in frame to give high spring rate
IPC: F16F3/087
Filed: 1975-08-20
Abstract: The visco-electric suspension system uses five elastomeric springs (E). Three of the springs are attached at one end to the bar (C) supporting the load (F). The other ends of the springs are fixed to the bar (A) of the mounting frame. The other two springs connect the load (F) to the lower bar (B). Each spring is pretensioned to exert a force (F) so that the resultant force of all five springs balances the load. As the load moves from its rest position under the influence of external shocks there is a rapid increase in the restoring force which is five times as great as if only one spring were used.

The amount is made visible and at the same time the code and credit information are erased from the magnetic card. The telephone units used are counted and subtracted from the original amount made visible. The identification code and the new credit remaining at the end of the telephone conversation is transferred to the magnetic card. The device (1) is connected in the circuit of a telephone set (2) to allow or to stop the use of the magnetic card depending on the recorded information.
Patent FR-2346503-A1 (FR)
Title: Erecting platforms for sinking wells at sea - using deck rendered auto-elevating for working during erection, minimising danger
IPC: E02B17/02
Filed: 1975-11-20
Abstract: The method consists of erecting the working platform or deck on the base by means of a lifting system used on devices called "jack-up" using this working platform as a platform for erecting the towers and joining the towers and joining the towers with the platforms when their erection is complete. The lifting system is finally taken down for use on another platform. The "jack-up" system of lifting is an assembly of columns with toothed racks, activated by a raising mechanism, e.g. a motor driven pinion. For platforms with a steel base, use of cranes, working at dangerous heights and the use of jacks under loads are avoided. By assembly of the base part of the platform in sheltered water by means of "jack-up" used as gantry, the rack columns can be used for assembling the towers and the working platform, reducing the capital cost. For platforms with a concrete base, the towers and the platform can be erected in shallow water, avoiding towing.

Title: Insulating shim for cable clamping rings - acts as spring transverse to insertion direction for contact during temp. changes
IPC: H01R9/03
Filed: 1976-05-07
Abstract: The insulating shim, for inserting between the wires of a multicore cable with clamping ring, has spring properties in the direction transverse to the insertion direction so that contact is maintained even during rapid changes in temperature.

The spring shim has progressive spring characteristics such that beyond a certain pressure the shim no longer deforms. The casting resin in which the clamp is embedded is arranged so as not to interfere with the shim spring action.

Title: Distributor valve for petrochemical industry - has U=shape supply pipe connectable to any one of several outlet pipes
IPC: F16K11/074
Filed: 1976-10-15
Abstract: A distributor valve for use in the petro-chemical industry has an inlet pipe (4) with a rotatable joint (5) connecting it to a U-shaped pipe (3). The pipe is mounted in a rotatable disc (2) which enables the outer end (6) to be connected to any one of a number of outlet pipes (8) by sleeves (7). The sleeves have flanges forming annular pistons which enable them to be pressed against the end of the pipe or against the surface of the disc and so form a fluid-tight seal. To connect the inlet pipe to a different outlet pipe the sleeves are pushed downwards to allow the disc to be rotated and then pushed upwards to re-seal the joints in the new position.
