Patent FR-2248901-A1 (FR)
Title: Lathe chuck with counterbalanced pivoting jaws - uses net moment of centrifugal force on each arm to keep chuck tight
IPC: B23B31/18
Filed: 1973-10-24
Abstract: The arms (4) are mounted on axes (5) and carry the jaws (6). A movable ramp (11) is used to tighten the jaws. The components are separated by load transmitting pieces, (7, 10). When rotating, the moment of centrifugal force acting on the inner end of the arm is greater than on the end carrying the jaw. This prevents the chuck loosening due to centrifugla force, or, depending on weights and sizes, can increase the grip. Weights (20) fixed to the lever can be changed to alter the gripping characteristics of the chuck. Seals (16, 19) are used to close the inner spaces of the chuck, so that it can be filled with grase to lubricate the mechanism, and there are cover plates removable for adjustments.

Title: Impregnating carbon with metals - by heating carbon fibre in alkali-metal vapour to improve subsequent bonding with molten metals
IPC: C22C49/14
Filed: 1974-02-01
Abstract: Carbon is impregnated with metals, in order to improve the adhesion between these materials, by exposing the carbon to an alkali-metal in a controlled atmos. in order to insert alkali atoms between the panes of graphite in the carbon; raising the temp. to produce a vapour pressure due to the alkali-metal and placing the obtd. cpd. of carbon and alkali-metal in contact with a molten metal to form a composite or coated material. The reaction between the alkali-metal and the carbon can be undertaken either in vacuum or in an inert gas. Process is used, e.g. in the mfr. of composite materials consisting of metals reinforced by carbon fibres. A strong bond is formed between the carbon and the metal, as the presence of teh alkali-metal results in improved wetting of the carbon surface.

Patent FR-2240691-A1 (FR)
Title: Poultry suspension hook for slaughtering plant - for use with automatic drawing machine
IPC: A22C21/00
Filed: 1974-08-12
Abstract: Hook is guided on a suspending and transporting rail. In the case of small chickens, the drawing machine was liable to pierce the carcass and cause serious damage on the return course of the rotating element of the drawing machine. The difficulty was avoided by means of a spiral spring linking the rolling carriage and the locking grip for the feed; the spring is pressed downwards and extends during the penetration of the carcass by the rotating element of the machine. The advantage of the special hook lies in the fact that the complicated mechanism of the drawing machine does not need to be modified when dealing with small birds. The hook is made of stainless steel and the grip for the feet may itself be fitted with elastic, synthetic elements which can extend donwards under the effect of a force directed in this manner.
Patent FR-2293327-A1 (FR)
Title: Automatically stable shock absorber - has hollow piston rod drawing oil into chamber via valve
IPC: B60G17/015
Filed: 1974-12-04
Abstract: The shock absorber simultaneously gives shock absorbtion between suspended and non suspended masses and horizontal stabilisation of a vehicle. It has a system to brake the piston rod when a wheel force is applied, the efect being given by a "pilot" hydraulic pressure. Suppression of absorber extension is given by the closure of the slide cancelling pressure in the work chamber, this pressure being the "pilot" pressure source. The piston rod (1) is hollow and draws oil into a chamber (A) via a valve (2) and stops flow across the piston (3) by a non return valve. An acceleration detector (6) acts on another piston rod (7).

Title: Heat recovery system for industrial process - has gases passed through turbine to heat exchanger and purified before expulsion to atmosphere
Inventor: BEDUE ABEL
IPC: F02C6/00
Filed: 1976-06-01
Abstract: The waste gases at a temperature of 500 deg.C from an industrial process such as cement or glass manufacture are transmitted from the collector (1) through the pipe (2) to a turbine (4) which drives a compressor (8) and a generator (15). The gasses then pass through a heat exchangers (5) which supplies hot water to the pipe line (18).

Title: Mechanised removal of enamel slurry - from edges of domestic utensils during mfr. using rotating wiping roller
Inventor: BAHR PETER
IPC: C23D11/00
Filed: 1976-09-17
Abstract: Process for the mechanised wiping of substrate edges when applying enamel or similar coatings, esp. on domestic crockery. The axis of rotation of the utensil is at approximately 90 degrees to the axis of rotation of the roller employed to wipe enamel off the edge of the utensil. The wiping motion is pref. applied from the front onto the edge of the utensil. Due to this configuration, the edge of the utensil no longer exerts a cutting action on the wiping roller so the working life of the roller is greatly increased; this means less frequent stoppage of the enamel coating machine; the elimination of repairs to a rubber belt formerly used and which has a very short life; and the overall result is savings in time, cost, and faulty workpieces.

Abstract: The brick wall has a conventional construction with superimposed and bonded horizontal courses, and has a compressible adhesive strip (12, 16) in the horizontal bedding joints. The strip replaces conventional mortar and derives a wall suitable for construction by non-skilled personnel. The strip (12, 16) has adhesive on both the top and bottom horizontal surfaces. The strip may be of a water resistant cellular foam and the adhesive may be a quick-setting polymer. The vertical joints may be filled by adhesive biscuits (20a) of a similar construction. Longitudinal continuity between blocks may be provided by toggle joints with keys (24) placed in opposed grooves (28) in adjacent brick ends (26). The wall may be made waterproof by utilising it as the outer leaf in cavity construction with positive drainage at the foot of the cavity.

Title: Synthetic plastics post prodn. - by bombarding extruded plastics tube with sawdust to give appearance of timber
IPC: A01G9/12
Filed: 1977-04-21
Abstract: Plastic material is extruded through a die over a mandrel to produce a hollow post. At the exit from the die the plastic passes through a hollow circular member (I) whose inner surface is open to the plastic post. (I) is connected to a vibrator which causes vibration transverse to the axis of the post. A reservoir has a discharge funnel leading to opposed jets directed to opposed open ends of (I). The reservoir is fed with sawdust under pressure which discharges into (I) so that it is embedded in the still soft plastic causing blisters and giving the post the appearance of timber.
