Patent FR-2257388-A1 (FR)
Title: Flagstone grinding and polishing machine - has height regulating feelers for stones of uneven thickness
IPC: B24B7/22
Filed: 1974-09-13
Abstract: The flagstones travel in relation to the machine, which is equipped with a flat grinding plate on articulated mountings. Where the stones have irregular shapes or thickness, variable-height feelers control switches regulating the upward and downward movement of the grinding plate, and if necessary of its mountings also. Entry of a stone into the machine can be arranged to cause lowering of the grinding plate and exit its raising, and the mountings can be moved each time the grinding equipment risks running off the edge of the stone.
Patent FR-2289109-A1 (FR)
Title: Container for terrace gardens - has different units connected by angle section edge flanges bolted over seals
IPC: A01G9/02
Filed: 1974-10-31
Abstract: Each units comprises a roughly square base (1, 1') bordered on two sides by angle section flanges (2, 2') and on the other two sides by sides. The angle section flanges are connected to the base by flanges (21). They have vertical flanges (20)n in which are drilled holes by means of which adjacent units are attached to one another with nuts and bolts. The joining of two adjacent units leaves a drain (210) below each join. The units can be of different types, e.g. with only one side wall (3) and a base, or with just the base alone enabling a large number of different shapes of terrace garden to be built up. The soil with which the units are filled helps to keep the whole steady.
Patent FR-2290273-A1 (FR)
Title: Preshaping of components of ductile materials for subsequent machining - to provoke swarf removal as discontinuous chips
IPC: B23P25/00
Filed: 1974-11-06
Abstract: Preshaping of semi-finished components which are subsequently to be machined, esp. by turning on a lathe, where the component is forged and/or machined to produce flats or grooves across the direction of the subsequent cutting axis. The method is used esp. for making machined parts from preforms of ductile materials such as ferrous or copper alloys, esp. brass, or certain plastics materials. The discontinuities or the variations in swarf thickness during subsequent machining of the non-circular or non-planar profile cause the swarf to dissipate as individual chips instead of coming off as a continuous ribbon which can trap heat and can jam between the workpiece and the tool or other relatively moving parts.

Title: Electrolytic treatment of water in distribution plants - with addn. of zinc to provide protective deposits in pipes etc.
IPC: C02F1/461
Filed: 1975-03-17
Abstract: The electrolytic process for correcting the physicochemical equilibrium in water distribution plants which comprises subjecting the water to a primary electrolytic modification, is improved when predetermined amts. of Zn are introduced in to the plant as a function of the flow of water from the plant. The primary modification corrects the chemical equilibrium and lowers the hardness while increasing the amt. of free CO2, and is applied by a system of low voltage electrodes in the plant. During treatment a thin- uniform and protective layer of Zn-contg. scale is deposited in the pipes even when the equipment is not galvanised.

Title: Curds pouring tank for cheese mfr. - with mechanised discharge of curds of consistently high quality
IPC: A01J25/08
Filed: 1975-04-08
Abstract: The tank is a horizontal, half cylindrical channel with flat, vertical ends, one of which has a rectangular discharge opening fitted with a vertically displacable shutter formed with a pouring spout in the top edge. Means are provided for raising the tank can be raised relative to the shutter and/or the shutter lowered relative to the tank, thus vacating the opening so that curds pour out over the spout. Pref. the shutter is fixed and the tank is raised on a lazy tongs linkage, e.g. by a hydraulic cylinder. Within the tank a moving wall can be coupled to the tank raising/shutter lowering mechanism so that it moves longitudinally of the tank to push curds towards the opening, pref. via a narrow gap beneath a vertical, mixing baffle near the discharge end. The tanks do not have to be high enough to produce gravity discharge flow. Curds and whey sepn. is overcome as they are forced through the gap below the mixing baffle.

Patent FR-2318687-A1 (FR)
Title: Vertical spindle rotary sorting machine - has electromagnetically operated receiving compartments with swing down bases for sideways discharge
IPC: B07C5/26
Filed: 1975-07-21
Abstract: The rotary sorting machine operates automatically after feeding the articles through a vertical chute (1) at the top. It has a set of receiving pockets (2) which are so close together, that each article must fall into a pocket. The bottom (4) of each pocket tilts down to release its contents to a sloping chute (11) at the side.

Patent FR-2342447-A1 (FR)
Title: Dual purpose bath tap - has spring loaded valve to prevent simultaneous supply of water to shower and to bath
IPC: F16K11/044
Filed: 1976-02-24
Abstract: The dual purpose bath tap has an inlet with an external screw thread for connecting to a hot and cold water mixing tap. When the mixing tap is turned on water flows through a passage-way and out through the fitting into the bath. When the shower is required, the user pulls a knob downwards so that the force of a spring is overcome and the valve head is pulled onto a lower seat. The water then flows to the shower. The pressure of water in the second passage-way keeps the valve pressed on its seat. When the water supply is turned off the valve opens automatically.

Title: Electronic control for car accessories - has fingertip control tabs near steering wheel and linked to logic control circuits
IPC: B60S1/48
Filed: 1976-10-28
Abstract: The electric controls for the car are replaced by press tabs near the steering wheel and linked to a central logic control by low current lines. The logic control operates the various electric components such as lights and wipers. The driver does not have to release the steering wheel, nor loose driving concentration to operate the switches. The press pads are arranged in patterns on common bases. Each tab, when operated, connects the appropriate signal line to earth. The logic control can be extended so that e.g. the direction flashers are only cancelled when the steering is centred, and after the vehicle has travelled a minimum distance. It can also be arranged so that the self cancelling effect is inhibited when reversing.

Title: Mfr. of web of parallel weft threads for reinforcing paper, film, etc. - by positioning threads in circular form, aligned loops formed in parallel, cutting the loops and tensioning the thread sections formed
Inventor: SEGUIN PIERRE
IPC: D04H3/12
Filed: 1977-01-12
Abstract: A web of parallel weft threads is produced by (a) position >=1 continuous thread into a more or less circular form, (b) aligning the loops formed parallel to each other, (c) cutting the loops, so as to form successive separate lengths of weft thread, (d) tensioning progressively the thread sections formed. Before the cutting operation, the more or less cylindrical web of thread is provided with >=2 thread-like elements located one on each side of the line along which the web of threads is to be cut, so as to hold the ends of the sections when they are laid flat. The density of the web can be varied by altering the speed of the belts around which the yarn is laid, without having to fit replacements, as it necessary with known machines forming spirals. The web can be wound for use elsewhere as a reinforcement for paper, film, etc.

Title: Treatment of alcohol with internal hydroxy impurity - using alkali treated alumina opt. with hydrogenation
IPC: B01J21/04
Filed: 1977-04-18
Abstract: Treatment of an alcohol or a mixt. of alcohols having mainly terminal -CH2OH gps. but also an amt. of internal CHOH gps., is carried out by contacting the alcohol(s) in the liq. phase at 200-300 degrees C with a catalyst based on alumina treated with alkali hydroxide. A simultaneous or post-hydrogenation is pref. also carried out to reduce the iodine index, e.g. using an Ni catalyst at 115-140 degrees C at 20-34 bars pressure. The process is partic. useful for purificn. of 10-18C alcohols. The quality of long chain alcohols formed by synthesis from a natural alcohol e.g. copra oil and ethylene and a trialkylaluminium is improved. The alcohols formed contain diol impurities having internal CHOH gps which are dehydrated and opt. hydrogenated by the present process to pref. alcohols. The treatment is effected rapidly.
