Patent FR-2017822-A1 (FR)
Title: Gas-tight, chemically-resistant receptacles of - metallised, filled polyolefines
IPC: B65D85/84
Filed: 1969-09-11
Abstract: Polyolefins contain up to 40%, preferably 10-30% w/w of filler relative to the mixture, metallised by chemical reduction, and possibly subsequently treated galvanically. Metallisation decreases the permeability of the polyolefin considerably, and increases rigidity, whilst other properties e.g. chemical resistance are unchanged. Also, due to metallisation, the recipients acquire a very decorative scratch-resistant surface. They can be varnished.

Patent FR-2112369-A1 (FR)
Title: Warp let-off beam - has torque applying mechanism to control warp tension
IPC: D03D49/06
Filed: 1971-10-29
Abstract: A rotatable endless screw is connected by a shaft to a gear carried on the warp let-off beam, and a guide provided on the screw carries a weight which applies a torque to the warp beam via the endless screw, the shaft and the gear. Warp yarn passes from the warp beam over a bar mounted on a pivotal arm, and increase in warp yarn tension lowers the bar, causing the lever to pivot and actuate a clutch to transmit rotation to the endless screw. As the screw rotates the guide moves along it thereby reducing the torque applied to the warp beam by the weight.

Title: Hydraulic shock absorber piston - washer between centring and intermediate washers forms passages through piston
IPC: B60G13/08
Filed: 1973-10-19
Abstract: The piston (1) is mounted on rod (5) and fixed by a nut (6) on a stack formed by a retaining disc (7), a thrust washer (8), a centering washer (9) which has radial slots (9a) and a valve washer (3). Permanent passages are obtained by interposing an intermediate washer (10) between the thrust washer and the centring washer. This intermediate washer has a diameter a little greater than the centring washer and has slots (10a) aligned with the centring washer slots. The intermediate washer diameter is about 5-20% greater than the centring washer diameter. This results in no wear on the piston, only on the disc (7), thrust water (8), centring washer (9) and intermediate washer, and there are permanent passages through the washer stack to the piston passages.

Title: Cleaning machine for artificially bred mussels - for removing parasites etc without tearing the attaching filaments
IPC: A22C29/00
Filed: 1974-07-26
Abstract: The mussels, when removed from their breeding beds, are in clusters made up from lichens and mosses to which they are attached. Each mollusc should be detached from its support and all the impurities attached to its shell removed without tearing the ligament which joins the mussel to the remainder of the group. The new machine breaks up the clusters, sorts the mussels by size and removes the adhering parasites. It consists of a frame supporting a motor and reducing gear driving a cylindrical shell and a cylindrical sieve made from a series of circle of round bars. These are secued between end flanges. The mussels are introduced. A row of jets, fed with sea water, facilitate the flow of the charge down the inclined plane to the annular space between the inside of the shell, fitted with rods, and a steel sheet. The latter is equipped with a surface of bristles which clean the surface of the mussel shells without causing damage. The mussels are also sprayed with water from other rows of jets. The impurities lichens and small pebbles, as well as the small mussels are evacuated through a trough; the cleaned mussels are evacuated into a receiving tank. The various cleaning operations are effected with the min. of losses through tearing the filament or crushing the shells.

The wood stove may have an air circulator.
Patent FR-2243442-A1 (FR)
Title: Electronic overload detector for counter - uses reference oscillator and comparator with Hall generator
IPC: G01R21/133
Filed: 1974-09-09
Abstract: The counter consists of two crown-shaped wheels, th tips of the crowns being permanent magnets. A Hall generator is mounted between the two wheels and produces a series of pulses when the wheels turn. The series of pulses is amplified and is passed to the gate where it is mixed with signals from the reference oscillator and difference signals are used to drive a stepping motor. This motor drives a counter when the number of pulses from the Hall generator exceeds the number of pulses from the reference generator. Further counters and stepping motors may be used.

Title: Floating chain of oil filled cylinders - for submerging heavy structures to depths of 1000 metres in under water oil explotation
IPC: E02D23/02
Filed: 1975-01-14
Abstract: Floating submersion chain for use in underwater oil exploration where it is necessary to submerge to a depth of 500-1000 m, heavy structures such as storage tanks. Each link in the chain consists of a cylindrical tank filled with oil and containing a small balloon connected to the outside so that water can enter the tank as the depth increases without any oil escaping. At each end of the tank are rings allowing it to be joined up to other tanks by conventional chains. Once the structure has been lowered to the correct position, the chain is unhooked and floats to the surface. Tangling of the chain is prevented by the last link having flaps on the outside of a central body which open out to form a cone thus slowing the movement of the chain by acting as a brake.
