Patent FR-2257791-A1 (FR)
Title: Carburettor operating with constant vacuum - has a double truncated cone shaped chamber with a restricted inlet
IPC: F02M17/08
Filed: 1974-10-23
Abstract: A fuel supply system has two concentric flow-connected circular channels having a circular cross-section and an open circular slit. The opening of the inlet to the carburretor cchamber is varied in size by a membrane-operated throttle body. A finger rigidly couples the throttle body with a needle-shaped throttle part in the main fuel supply line. The inner circular channel incorporates a heater for preheating the fuel before it leaves the circular slit. The throttle body has a double truncated cone shaped head with an axial cylindrical cutout by means of which it moves on a central guide part having an axial aperture which is flow-connected to an upper vacuum chamber enclosed by a cover and a spring loaded membrane. When the throttle flap is opened, the suction action in the vacuum chamber moves the throttle body upwards and thereby enlarges the inlet opening.
Patent FR-2297515-A1 (FR)
Title: Oppptiittttiiiicalllllllaally operated thyristor current controller - with current varying according to the amount of light allowed to fall on a photocell
IPC: H02P7/292
Filed: 1975-01-07
Abstract: The amount of light incident of the photocell (5) can be varied, for example, by the pedal-controlled shutter (8). The photocell functioning as a variable resistance is connected in series with the capacitor (12). This capacitor charges up to a certain threshold voltage and then discharges into the diode thyristor (13) which in turn switches on the reversible thyristor (3). Thus the proportion of each cycle of the alternating supply (1) for which the reversible thyristor is conducting and hence the supply of current to the load (2), for example a sewing machine motor, is determined by the amount of light allowed to fall on the photocell.
Patent FR-2270665-A1 (FR)
Title: Disposable cleaning pads for cables are sealed in container - and consist of flat sponges saturated with organic solvent
IPC: A47L13/18
Filed: 1975-01-09
Abstract: The disposable cleaning pads, for cables, are contained in a sealed container until one is required. Each pad is circular and flexible so that it folds around the cable and can then be drawn along the latter by hand picking up any dirt present on the cable's outer sleeving. Each pad consists of a wide-pored porous material saturated with an organic solvent that oozes from the pores and loosens any unwanted material on the surface of the cable's sleeving. In a variation on this, the pads are formed as tubes into which the user pushes his hand. The sponge tubes are stored flat.

Used esp. for tyres for racing cycles, to cover the quick release device, such as sliding fastener. The lining reduces the risk of abrasion and puncture of the inflated inner tube by rough spots or projections on the quick release device, without introducing excessive wt. The tape is of cotton cloth coated on one face and cut at an angle of 45 degrees to the weave axes. The coating is of rubber or a flexible plastic material.

Title: Transparent pocket for attaching label to article - has narrow tear strip along three edges, and wide tear strip down fourth edge
IPC: B42F7/02
Filed: 1975-02-05
Abstract: The label carrier and protector consists of a pocket into which a label can be inserted, then adhesively attached to a parcel or container so that the label is visible. It has a transparent sheet with a margin of adhesive (8) around four edges and carrying a silicone coated paper layer of the same size. A cut (9, 10, 11) made around three sides, forms a tear strip (13) which is only half the width of the adhesive strip, leaving a narrow strip of adhesive exposed. Another cut (12) down the fourth side produces another tear strip (15) which is as wide as the adhesive strip. This enables the label to be inserted along the line of termination of the adhesive. The pocked can now be attached by the adhesive strip which runs around four edges.

The ends of the U-section stringers (2) fit through the slots in the uprights and are twisted so that notches (15, 16) engage the uprights to lock the stringers. Transverse members (3) locate on top of the stringers to lock them in place. Notches (18) in the transverse member legs fit over the cut away webs of the stringers. Each transverse member has slits (19) along its top face for locating the steel shelves.
Patent FR-2300894-A1 (FR)
Title: Shock absorber for sledge mounted mine roof support - is membrane pressure accumulator housed inside piston of actuator strut
IPC: E21D23/00
Filed: 1975-02-12
Abstract: The mine support has a sloping arm carrying a roof support at the top, and is mounted on a sledge at the bottom. It has a fluid-operated stay between the arm and the sledge which swings the arm as required, and holds it in position. This stay has a piston (9) attached to a rod (10) which extends to raise the arm, and the piston divides an upper fluid-filled chamber from a lower one (14) inside the cylinder housing the piston. The lower chamber is connected to a stop valve (15) and a safety valve (16) in the supply line. In order to absorb any sudden shock force on the roof support, a standard membrane pressure accumulator (20) is housed inside the piston, in a chamber (17) which communicates with the lower chamber (14) through a set of holes. This has a faster response than a conventional safety valve.
Patent FR-2279670-A1 (FR)
Title: Chlorine removed from zinc sulphate soln. - obtd. during leaching of zinc ferrites etc
Inventor: BODSON F
IPC: C01G3/05
Filed: 1975-03-25
Abstract: Chlorine is removed from a soln. of zinc sulphte by first reducing th pH to 2.6 by addn. of sulphuric acid then increasing the content of cupric ions in soln. to a value such that after elimination of chlorine by pptn. as CuCl. the excess cupric ions are present to an amt. >0.5 g/l. The CuCl is then treated with NaOH to recover Cu2O which is recycled forming fresh CuCl. The process is cheaper than the prior art process of pptn. with Ag, which tended to lose some of the silver.
Patent FR-2305353-A1 (FR)
Title: Cardboard packaging with impermeable lining bag - has side flaps partially folding over lining bag before end flaps
Inventor: MALCOLM JAMES A
IPC: B65D5/60
Filed: 1975-03-28
Abstract: The package (14) and lining are erected and the bottom sealed. The top has two opposing flaps (11a, 13a), each half the opening width, and two longer adjacent opposing flaps (12a, 14a) which overlap. The lining is fixed to all four flaps so that, when presented to the machine with these vertical, the lining mouth (32) is automatically open. After filling, the long flaps (12a, 14a) are returned horizontally outwards, which pulls the short flaps (11a, 13a) inwards. These can be closed flat, trapping the lining between them and leaving a length (34) free for sealing. The long flaps are then closed over and sealed. An easy open tab (40, 41, 80, 81) is provided.

Title: Self:priming pump unit - has vane pump connected between centrifugal pump inlet and outlet branches
Inventor: BOVY HENRI
IPC: F04D9/04
Filed: 1975-09-25
Abstract: The self-priming pump unit has a centrifugal pump with inlet and outlet branches, and a vane pump similarly equipped. The vane pump inlet branch is connected to that of the centrifugal pump by a bypass-pipe containing a jet, and its outlet branch is connected to that of the centrifugal pump downstream of a non-return valve in the latter. The two pump rotors can be keyed to the same shaft. Once priming is complete, the discharge pressure is sufficient to cause the vanes to retract, so that there is no wear on the vane pump, and there is no need for any large quantity of liquid to be held in reserve.

Title: Mechanical accordion tuning device - has controlled pressure chamber containing rods for actuating respective accordion keys
IPC: G10G7/02
Filed: 1976-03-05
Abstract: The device for tuning an accordion has a pressure chamber (1) which can be brought to a pressure above and below atmospheric in alternation. This causes vibration of the vanes corresponding to the different notes, in dependence on the actuation of the accordion keys (7,8,9). These vanes being accessible to allow them to be tuned. The side of the pressure chamber (1) into which the accordion is inserted has means for sealing the pressure chamber (1) around the accordion. A number of rods (22, 23, 24) are contained in the pressure chamber (1) and can be operated externally, for actuating the respective keys (7,8,9) of the accordion key board (10).
