Title: Appts for unwinding photographic film band - has drive rollers with flats releasing pressure to correct band position
IPC: B65H23/02
Filed: 1974-05-14
Abstract: The band is rolled onto one spool (B) and unwound from this to be rewound onto another (R), the band (5) forming a straight length between. Each side of the band is a roller (1, 2) mounted (7) on axes (3, 4) parallel to the band surface. The smaller diameter roller (2) is free running and acts as a back up roller for the driving pressure exerted on the band by the larger diameter driven roller (1). Both rollers are coated with a resilient material (6). The drive roller (1) has a longitudinal flat on its outer surface. As the roller rotates the flat relaxes the driving pressure on the band, allowing the band to return to its correct position.

Title: Device for orienting travelling support - has unit moved by guides between positions of equilibrium
Inventor: DUBUS GERARD
IPC: A24C5/358
Filed: 1974-06-11
Abstract: The device alters the angle of a support travelling along a rail, particularly the support of a hanger conveyor attached to a carriage by a suspension rod. On the latter (2) is a unit (6) having at least two positions of stable equilibrium, altering the angular position of the support in relation to the carriage (4). Guides (10, 11) move the unit from a first equilibrium position to an intermediate position, generating in the process a force between support and carriage which moves it on to the second equilibrium position. The unit can have four equilibrium positions evenly spaced, being typically in the form of a dog-clutch.

Title: Bitumen filler from bauxite residue - by adding lime and drying directly to powder
Inventor: BINGS HUBERT
IPC: C09C1/00
Filed: 1974-07-25
Abstract: The process is a modification of a known process in which after dissolution, quick or slaked lime or milk of lime is added to the bauxite residue, 3-10 wt.% lime, calculated as CaO, being added based on the dry quantity of the residue, lime being added in the zone of the washing settling tank or before the filtration of the bauxite residue. In the present process, the pre-treated product, moist by filtration, is directly dried into a final product with perfectly-flowing grains. The object is to eliminate a milling step and to improve properties to bitumen-filler mix.

Patent FR-2293748-A1 (FR)
Title: Taximeter with DC tachogenerator coupled to speed unit - has voltage source producing output signal corresponding to time function
IPC: H03K3/282
Filed: 1974-12-02
Abstract: The taximeter (10) contains a d.c. tachogenerator (12), with an input spindle which can be coupled either to the speed cable of the taxi or the gear box or the wheels. The tachogenerator provides a direct current output signal which is proportional to the speed of the vehicle. A constant voltage source (14) produces an output signal which corresponds to the time function. The two outputs are fed to a direct voltage selection unit (16), which selects the higher of the two which is then fed to a voltage controlled oscillator (18). The output of the oscillator is fed to a counter (21) whose output is then fed to a digital read-out unit (22). The readout is a function of the analogue signal, when the latter is such that it corresponds to the movement of the vehicle at a speed that is less than a predetermined value.
Patent FR-2299589-A1 (FR)
Title: Press overloading safety device - has compression spring to cut out driving motor switch
IPC: F16P3/04
Filed: 1975-01-31
Abstract: The punch (3) of the press (1) houses a compression spring (7) in its upper end. The outer end of the spring (8) is covered by a cap (10) which can slide axially over the flange (6) screwed into the punch (3). The cap (10) carries a switch (13) forming part of the control circuit of the motor driving the press. The actuating load (F) is applied through the cap and is normally insufficient to compress the spring (7). Under abnormal loading the spring (7) is compressed and the switch (13) moves away from the arm (19) which is rigidly attached to the punch (3). The consequent removal of pressure from the press button (15) opens the switch (13) and cuts out the driving motor.

Title: Fluids separator, with superposed compartments - partic. for degassing motor-fuel, with large sepn. front giving max. flow rate
IPC: B01D21/00
Filed: 1975-07-04
Abstract: An appts. for sepg. foreign substances, fluids or solids, from a flowing fluid contg. them in suspension, consists of superposed compartments through which the fluid flows horizontally. The compartments are formed by joining rectangular sections at an angle and making a notch at the part where the liq. enters. The sections are inclined transversely to the direction of flow, at a slope which falls or rises according to whether the foreign substance is more or less dense than the liq. In addn. the elements are inclined longitudinally, at a slope which falls or rises as the transverse slope falls or rises. There are vertical partitions between the elements, forming vertical collectors. The sepd. foreign substances slide sidways on or under the slope, to the collector and downstream at the same time, keeping the layer as thin as possible. Use partic. as a degasser, to remove from a motor fuel, before measuring it, the air aspirated during pumping. Also used for e.g. sepg. hydrocarbons from water, or metallic particles from oil, with a suitable outlet valve. Evacuation of the degassing areas occurs as rapidly as the bubbles of air arrive there. This allows the great rate of sepn., possible with the superposition process, to be fully achieved.

Title: Precision bending control of a metal section - by noting the bending parameters, for aerodyne pipe system prodn.
Inventor: GRASSET MICHEL JEAN VICTOR
IPC: B21D7/14
Filed: 1975-07-09
Abstract: A linear measurement of the moving metal section is taken before each bending stage, from a reference point on the section. Then an angular measurement is taken when the section has to be bent according to a plane different from that of the preceding bending stage during the rotation of the section about itself; the measurements being taken upstreams of the bending appts. The process is partic. useful for producing aerodyne pipe systems. The measurements are visually displayed and are used for automatic control.

Filed: 1975-10-22
Abstract: Circular, thin-walled irrigation pipe made of a synthetic material has a wall with transverse corrugations, and at least one row of openings extending longitudinally down the pipe. A row of hollowed-out projections (2), at intervals along the pipe, extends parallel to the row of openings and projects radially beyond the external diameter of the pipe, defined by the external ridges of the corrugations. The pipe can be laid directly onto the ground in the correct position without a trench utilising a device to adjust the projections so that the openings for the penetration and subsequent distribution of water are the correct height. Under normal circumstances, the openings will face downwards.
