Patent FR-2252207-A1 (FR)
Title: Electrostatic charging blade for a film chilling roll - operated hot to prevent material condensation on to the blade
IPC: B29C47/88
Filed: 1973-11-28
Abstract: High voltage blade generating electrostatic charges to apply freshly extruded thermoplastic film to the surface of a chill roll, where the blade is maintained at a temp >=200 degrees C Used esp. for blades mounted within 10 mm of the film/tool contact line. The high surface temp. prevents contamination of the blade surface by condensation of volatile materials from the film. Increased blade life allows a more rigid blade to be used, in turn allows film transport speeds to be raised from =30m/s to >=35 m/s because of improved field flux uniformity, compared with use of a wire electrode which can vibrate more easily.

Title: Mechanism for separating cans into rows - has pivotal guides feeding two rows to pivotal row guides
IPC: B65G47/71
Filed: 1974-01-31
Abstract: The mechanism may be applied to food tins which are fed to the machine in a vertical position on a conveyor (4). The tins pass onto a second conveyor between widening guides (7), until they reach the first separating pont to pass between the two pairs of guides (9) and (10). The tins then pass onto the second separating point. At this point rocker arms (11) push every other tin of each row sideways so that it is guided into the central channels between (16a) and (16b). The rocker arm is operated by means of a ram (13). The marker mechanism at (17) and (18) signals when a channel is full.

Title: Telephone charge counting unit - has analogue to digital conversion unit connected to transformer
Inventor: BUZY-DEBAT JEAN-MARIE CLAUDE S
IPC: H04M15/10
Filed: 1974-07-26
Abstract: The telephone subscriber charging unit receives conventional charging signals of a sinusoidal form via a transformer unit across the line. Its two primary windings have one end connected to the line and the other joined to form a mid-point connection between the two. The windings are phase to give a zero output for identical voltages on the lines. The secondary is connected to a parasitic protection circuit. Bridge rectifiers and a phototransistor are used to convert the charge signal into a binary form for use by an electronic counter. This unit replaces electromechanical calculators and uses the existing charge code signals.

Title: Double flow grease distributor - has double acting valve ball under spring loaded stop rod through piston
IPC: F16N7/38
Filed: 1974-07-26
Abstract: Each closing piston closes a chamber containing a ball acting as a double acting valve. It is open at the end of the piston stroke and a rod can slide slightly axially and is returned by a compression spring. The force of the spring is less than the force on the ball on its seat when pumping grease and greater than the force produced by the ball in the direction of its seat when the ball is raised by an amount corresponding to the difference between the desired ball lift and the total movement of the stop rod. The closing piston (1) has a central chamber (2) with the ball (3) acted on by the grease. The stop rod (7) is solid to a moving bung (8) with an internal passage (9) with a washer (10) and another washer (11).

Title: Furniture castor with two cup-shaped rollers - has rotatable operating member for sprung brake shoe
Inventor: SCREEN STAFFORD THOMAS
IPC: B60B33/02
Filed: 1974-08-01
Abstract: The castor braking means comprises a brake shoe, and an operating member providing a cam surface, the brake shoe being spring-urged towards the cam surface, and the operating member being mounted for rotation about an axis from an "off" position to an "on" position whereby the cam surface is moved to urge the brake shoe against one of the inner surfaces of the roller to effect locking of the roller. Preferably, when the braking means is in its operative position, movement thereof to its inoperative position is restrained, by arranging the cam surface in a manner such that forces acting thereupon do not act to effect movement of the operating member towards its "off" position.
Patent FR-2287668-A1 (FR)
Title: Shell-side shroud with short sleeve for each tube - protects tube to tube-sheet joint against high gradient
Inventor: POUDEROUX PIERRE
IPC: F28F9/00
Filed: 1974-10-11
Abstract: Short sleeves are slid over each tube in a heat exchanger bundle, one end of the sleeves next to the tube-plate being free with the other end welded into a drilled plate which is also slid over the tubes. This drilled plate fits into the inside of the shell and is welded to a collar, the bottom edge of which is held against the tube plate by a stud bolt fixed in the tube-plate and projecting through the drilled protection plate. At the lower end of the sleeves, close to the tube plate are one or more orifices which allow the shell-side liq. to flow out. Projecting through the plate and connected to an external nozzle is a pipe, which inside the shroud is perforated, used to withdraw samples of the shell-side liq. Another tube connected to an external orifice extending through the plate is used for gas sampling. The system is specif. used for heat exchangers with a liq. metal, e.g. sodium on the shell-side and boiling water on the tube-side. Liq. within shrouded area is relatively static and so there is a small temp. gradient between tubes adn tube sheet. The sleeves surrounding the tubes protect each tube from its neighbours. In case of leakage and violent reaction, pressure is released along annulus between sleeve and tube.

Title: Bee smoker producing cold smoke - has bellows and conical duct sucking smoke out of box in cold airstream
IPC: A01K55/00
Filed: 1975-03-20
Abstract: The bee smoker produces cold smoke to avoid antagonising the bees which can be burnt by hot smoke, and consists of a sheet metal box with a hinged (7) lid. It contains a grid supported on propos near the base. The cold smoke is obtained by a jet (20) of cold air produced by bellows (15, 16) consisting of plastic sheet (17) and a spring (28) fixed to the body of the smoker. This cold air passes through a cone producing a vacuum in the body of the smoker, and sucking the smoke out. It then mixes with the cold air and is blown out of the tube (5).

Title: Mfr of light weight building elements from fibre reinforced plastics - by cross-wise winding impregnated rovings onto a mandrel removing the resulting laminate and hardening
IPC: B32B5/10
Filed: 1975-12-10
Abstract: Mfr. of lightweight building components from fibre-reinforced plastics comprises winding plastics-impregnated rovings onto a mandrel to form cross-wound layers, and removing the resulting laminate from the mandrel and hardening. During the winding operation several rovings are combined to fibrous strands, the strands of any two crossing layers being arranged in adjacent and superposed relationship in such a way that they are bonded together like a textile. The finished wound laminate is then cut up according to the contours of the intended building components and these are finally shaped as desired and hardened. No special moulds fitted with vacuum ducts for close hugging of the parts to be moulded and hardened are required, hence relatively inexpensive and simple prodn. technique. The laminates have low tendency to delamination. Esp. suitable for carbon-fibre-reinforced laminates.

Title: Walkway fencing system with H=section posts supporting rails - may be used on box section traffic sign gantry with H=section straddling gantry beam
IPC: E04G21/32
Filed: 1976-05-18
Abstract: The walkway ballustrading uses 'H' form posts (10-12) to support two parallel rails (25, 25a) defining the walkway and is of partic. application on motorway type traffic sign gantries of box section members (2a). When used on a sign gantry the ballustrading forms a maintenance walkway.
