Title: Mfr. of writing head for wide graph plotter - uses partially coated coil of highly elastic metallic wire wound in several phases
Inventor: GEORGES ANDRE JULIEN PIERRE CH
IPC: G01D15/08
Filed: 1975-08-22
Abstract: A metallic wire (6) of high elasticity is wound round a spool in several phases, before each of which the coil has a different shape. Part of the coil is not altered during the winding. The turns here are interlaced with those placed during preceding phases s.t. the final winding has regular pitch. Certain parts of the coil are coated with insulation and positioned on the non-altered part of the coil, to form the writing head when placed in a support. The turns on either side of the coated parts are then divided up into groups corresponding to the altered part of the coil and to the number of phases of the coil. These form recording electrodes.

Title: Water pump for e.g. underdeveloped country - has linear electric motor drive with power generated using e.g. wind or solar cells
IPC: F04B17/00
Filed: 1977-03-31
Abstract: A water supply system intended for under-developed countries where surface water is scarce uses a double acting piston pump driven by a linear electric motor. The pump is placed at the bottom of a bore hole and supplied with electricity from a circuit which generates pulses to produce a reciprocating motion of the double piston. The electricity is generated from natural sources such as wind power or solar cells. The electric supply system incorporates accumulators or other means of energy storage for use when the natural sources are not available. This type of pump with a linear electric motor can run for long periods without attention.

Patent FR-2386338-A1 (FR)
Title: Metering hopper with variable speed coaxial lifting screw - for in situ blending prior to controlled flow discharge of particulate material, pref. with PTFE seal between screw and outlet
IPC: B29C48/03
Filed: 1977-04-08
Abstract: A metering hopper or discharging particulate material is fitted with a coaxial screw which can turn fast enough to prevent any discharging from the hopper via a cylindrical outlet. Fresh material is introduced by a screw feed into the outlet alongside the hooper screw. At high screw speedS, the feed is lifted into and recycled in the conical hopper body. Minor quantities of additives, colourants etc. can be added directly into the hopper (at any suitable level) and mixed with the recycling main feed. Slowing of the hopper screw allows mixed material to discharge at a rate inversely proportional to the screw speed. The seal between screw and outlet is enhanced by a sleeve of dry self-lubricating material such as PTFE. Suitable for manually or automatically controlled blending and dosing of granulated and powdered materials for extrusion or moulding.

Title: Thermodynamic heating and ventilating system - has controlled by=pass round extract air compressor to maintain constant ventilation rate
Inventor: REGEF ANDRE
IPC: B60H1/00
Filed: 1977-04-15
Abstract: A fan (12) extracts a constant volume of air from a building or other enclosure (L). The bulk of it is compressed in a compresser(1) which raises its temperature. It is then cooled in a heat exchanger(41, 42) in which it gives the heat up to fresh air drawn from the atmosphere (A) and delivered to the building (L) by a fan (11). The heat output is controlled by variation of the speed of the compressor. When the heat output is reduced the volume flow through the compressor is also reduced. a regulating valve (13) then partially opens a bypass (14) which discharges extracted air directly to atmosphere. The reduced flow through the compressor does not therefore reduce the ventilation rate of the building (L).
