Patent FR-2295927-A1 (FR)
Title: Bituminous concrete contg. powdered natural asphalt - has improved properties and uses less bitumen
IPC: E01C7/35
Filed: 1974-12-26
Abstract: Bituminous "coated" concrete, comprising a mixt. of gravel, sand, limestone flour (filler) and bitumen has part or all of the filler and part of the bitumen substituted by powdered natural asphalt. Pref. the proportion of asphalt in the mix is about 12% and the asphalt used contains about 9% bitumen. The amount of bitumen used is pref. about 20% less than normally used in concretes of this type. The concrete quality is improved because natural asphalt powder as filler can be much better impregnated with bitumen than filler treated in a mixer with liq. bitumen, permitting a reduction in the amt. of bitumen necessary.

Title: Colour display system for X-ray pictures - has colour encoding system for giving different colours with different levels of energy spectrum
IPC: H04N9/43
Filed: 1975-02-14
Abstract: The colour display system may be used for recording X-ray spectra in e.g. medical radiography. The video signal for the display is produced by an X-ray camera which receives radiation which has passed through the subject under investigation. The signal is amplified conventionally and it is then colour encoded. The coding system is determined by the energy spectrum which is received by the camera. The energy spectrum may be displayed as an image directly on a colour CRT and a computer may be used in the sequence for analysis of the X ray spectrum.

Title: Sandwich panels mfd. with resorcinol-type adhesive - using min. pressing time and min. temp.
IPC: B32B7/12
Filed: 1975-11-19
Abstract: Sandwich panels of variable thickness and consisting of different materials are mfd. by using a resorcinol-type adhesive, a min. pressing time of 24 hrs. and a min. ambient temp. of 18 degrees.

Title: Phase sequence detector circuit - has Zener diodes preventing lamp indicating when high and varying phase voltages exist
IPC: G01R29/18
Filed: 1976-06-14
Abstract: A neon lamp is included in a phase sequence detector circuit to indicate correct phase rotation. Zener diodes prevent the lamp indicating when there are high voltages between phases and varying widely. A neon indicator lamp (V1) is connected into one arm (AB) of a three phase star circuit. When supply phase rotation is correct voltage vectors (CA, CB) across components (R2, R4, R5) are in phase opposition generating zero voltage (AB) across the lamp. The lamp lights to indicate a fault. When a high and varying voltage exists between phases a capacitor (C1) in one arm stores energy giving a false signal. In this condition zener diodes (CR1, CR2) short circuit a resistor (R5) to eliminate the false signal.

Title: Heat exchanger for cryogenic working - has good thermal hydrodynamic characteristics
IPC: F28F13/00
Filed: 1976-08-18
Abstract: A seive type heat exchanger applicable in cryogenic operations is provided with filling pieces forming passages for the fluid; the sieves being formed from plate material having a considerably greater conductivity for heat than the filling pieces. The filling pieces and the sieves are stacked on each other alternately and are bonded into a block in which the sieves form meshes. At least two boxes are joined to the block at opposite sides, to distribute the medium through the passages in the block in which the sections of the sieve plates forming the separate meshes are inclined at an angle to the plane of the sieve plate. The angle of inclination of the section of the sieve plate forming the mesh in the plate is 45-90 degrees. The sections of each sieve between the passages through the heat exchanger and round the circumference are formed from solid plate, and these same zones may be provided with projections for fastening the sieve into the block. Gives better results than block exchangers with wire gauze sieves.

Title: Foam-lined tyre tread cavities to inhibit aquaplaning - prepd. by creating suction at the tread road interface
IPC: B60C11/117
Filed: 1977-04-01
Abstract: Annular rolling contact zone of a tyre tread features a series of cavities partially filled with a flexible foam pad and partially covered with a tongue of rubber trailing from the preceding transverse tread rib. Flexure of the rubber tongue when in the ground contact zone compresses the pad and generates a partial vacuum in the cavity which enhances road grip. Arrangement is esp. effective in overcoming surface tension and disrupting water films on wet road surfaces, to inhibit 'aquaplaning'. The power losses due to enhanced rolling friction are said to be compensated for by reduced need for positive braking when stopping or cornering at specific road speeds.

Title: Monitoring properties esp. pH of aq. solns. - using photodetector measuring monochromatic light transmission rate through the soln.
IPC: G01N21/25
Filed: 1977-07-11
Abstract: Properties of an aqueous soln. such as its pH value are determined by passing the monochromatic beam of a light source through it, pref. after a pH-sensitive indicator has been added to it. The proportion of the light transmitted is measured and converted into an electrical signal. Its amplitude is indicative of the desired property. This replaces the subjective (visual) determination of a colour change, when pH-papers or indicators are used, by an objective system. The new system is less expensive and easier to handle than electronic pH meters. The pH-value can be determined with an accuracy of 1/10 in a range from 1-14.
