Title: Checking of electrical resistance of cable during mfr - by measuring voltage drops in cable and reference using knife contacts
Inventor: MATHIEU GUY
IPC: G01R27/02
Filed: 1974-12-24
Abstract: The fabrication of the cable strand (4) is interrupted during the inspection and a d.c. current of at least several hundred amperes is passed in a nearby section of cable (5) of the same characteristics and, at the same time, in a section of cable (2) undergoing fabrication. On each section, two knife contacts (8, 9) are applied at a known separation and the voltage drop between the knives on each section is detected. The ratio between the variation in these two voltage drops and the voltage drop in the nearby cable strand is calculated.

Patent FR-2280018-A1 (FR)
IPC: F16L47/30
Filed: 1975-05-07
Abstract: A weldable subassembly for connecting branch pipes to a molded plastic main pipe is formed with a pair of hinged arcuate members adaptable to be placed around the main pipe and welded thereto by electrical current passed through an interposed mat containing electrical heating wires. The arcuate members are pivotally interconnected by a hinge member which extends on one side thereof longitudinally of the main pipe, and which enables separation of the opposite side of the arcuate members so that they may be placed about the pipe. The opposite sides of the arcuate members form a slight gap therebetween which also extends longitudinally of the main pipe and the heating wire mat has a longitudinal edge which is attached, by welding or the like, to the inner surface of one of the arcuate members at a point intermediate the hinge member and the opposite side of the arcuate member.

Excess powder can be removed e.g. by sieving. The coated expanded materials can be incorporated into cement, concrete, plaster, etc., using standard mixing techniques, to give fire resistant, lightweight, heat insulating materials.
Patent FR-2328888-A1 (FR)
Title: Automatic drum brake adjustment - has screwed element in one brake piston rotated via friction springs by relative motion of pistons
Inventor: MEYER YVES
IPC: F16D51/20
Filed: 1975-10-24
Abstract: The arrangement provides automatic adjustment of a drum brake. It comprises actuating means which respond to the relative motion of the brake pistons so as to cause rotation of a screw element relative to one piston thereby adjusting this piston in axial direction. The actuating means are arranged between the screw and the other piston and comprise springs which are capable of frictionally gripping grooves on the screw when they are subjected to torsion. Tosion of the springs is caused by axial piston movement due to each spring having a radially projecting end engaging an inclined groove in a bush secured to the other piston. The grooves are inclined in opposite directions so that one spring is operative during application of the brake, when the pistons move apart, and the other spring during release of the brake causing opposite rotations of the screw by different amounts.
Patent FR-2331064-A1 (FR)
Title: Light sensitive silver halide materials esp. for holography - has regulated silver halide dissolution rate and growth rate of development nuclei
Inventor: KOVACHEV METODI IVANOV
IPC: G03C5/31
Filed: 1975-11-10
Abstract: In the development of light-sensitive Ag halide materials, the dissoln. rate of the AgX and the growth rate of the development nuclei, which are on the surface and inside the AgX crystals in the emulsion, are regulated to grains with certain dimensions and a reflection factor and a distribution corresp. to the distribution of the electromagnetic field in the recording are achieved. Regulation of the dissoln. and growth rates is achieved by developing samples subjected to various exposures in an aq. soln. of 40-60 g/l Na2SO3, 1-15 g/l L-ascorbic acid, 4-8 g/l hydroquinone, 0.1-2 g/l metol, 0.01-0.1 g/l phenidone, 0.01-2 g/l pyrogallol, 0.1-0.5 g/l diethyl-p-phenylenediamine sulphate, 0.1-1.5 g/l amidol, 0.01-1.0 g/l kI, 1.0-5 g/1 KBr, 40-100 g/l Na2S2O3, 10-40 g/l NH4CNS, 30-50 g/l K2CO3 and 0.5-2 g/l AgNO3, using various concns. of the AgX solvent, developer or H ions in the soln., and determining the final compsn. of the developer from the results obtd. Used esp. in holography. Both the surface and internal development nuclei are developed and the size and optical properties of the grains are controlled. Infectious development is eliminated and additional fixing of the developed material is saved. The distribution capacity, signal-to-noise ratio, speed and diffraction effectiveness (DE) (of holograms) are increased.
Patent FR-2333615-A1 (FR)
Title: Bilateral ratchet spanner with V-shaped ratchet lever - uses alternative lever positions to authorise alternative cog wheel rotation
IPC: B25B13/46
Filed: 1975-12-05
Abstract: The ratchet spanner incorporates a tilting two-way lever ratchet (5) of 'V' shape. Clockwise rotation of the ratchet (5) causes the left leg end (5') to engage the teeth of an externally toothed socket (22) wheel (2), and limit the wheel to clockwise rotation. Reverse rotation has the reverse effect. The lever ratchet (5) is maintained in either alternative operational position by a straight blade spring (6). The spring (6) extends externally from the apex (53) of the 'Y' to a point (13) on the handle (1). The lever (5) is manipulated by a pin (7) projecting through a curved slot in a cover plate. The socket wheel may comprise an axle (2') with an axial socket (22) for the reception of bit spigots. The axle has an intermediary radial flange (2) in which the teeth are cut, and fits in a matching recess in the head of the handle (1).

Title: Tower crane installation process - uses tower erection rams with prop to lift base for travel bogie removal
IPC: B66C23/34
Filed: 1975-12-22
Abstract: The tower erecting rams (5) are extended slightly, to allow a prop (25) to be placed between the lower part (3) of the tower and the first bogie (16), after which they are retracted so as to lift the base (1) in relation to the first bogie, it being then chocked in this position. Extension of the rams then tilts the base again and lifts the second bogie (13), so that this can be removed. The rams are then retracted to bring the travel rollers (12) at this end down onto the travel rails (27) or a foundation and remove the chocks. They are extended again to lower the other rollers (11) onto the rails. The prop and first bogie are finally uncoupled.

Title: Double-deck silo for mixing particulate solids - esp. with wide size range, using only gravitational force
IPC: B01F5/24
Filed: 1976-01-09
Abstract: In a double deck silo for gravity-mixing of materials varying from powder to granular form, the floor of the upper silo is roof-shaped in two halves and has a number of outlets which can be closed. The vertical outlet pipes from the outlets in the upper silo floor terminate above impingement distributors in the upper part of the lower silo. Material to be mixed is dumped into upper silo by pneumatic distribution pipes leading from feed tank which can employ compressed air injection for ease of movement of material. When material level in upper silo in above 'roof ridge' of floor valves are opened and material from all parts of floor falls through pipes and is mixed by deflection on baffles in lower silo.

Title: Seaming carpet sections together using flexible seaming tape - precoated with adhesive before application to the carpet
IPC: D06H5/00
Filed: 1976-03-12
Abstract: Carpet sections are joined together by first impregnating or partially saturating one side of a flexible seaming tape with liq. adhesive and allowing the tape to become inactive and non-tacky. The undersides of the edges of two carpet sections to be joined are coated with an adhesive which contains a solvent for the adhesive used on the tape and both these sections of carpet are urged onto a piece of the tape. The adhesive on the tape is remoistened by the solvent and a cohesive bond is formed. The method of seaming carpet sections together is easy to execute and produces a strong long lasting carpet seam. The tape may be impregnated beforehand and stored until required.
