Title: Grit spreader mounted ahead of vehicle wheel - is heated by engine exhaust with distribution controlled to suit vehicle speed
IPC: B60B39/02
Filed: 1975-07-02
Abstract: A system for spreading grit on the road, ahead of the wheels of a vehicle, partic. during icy or snowy weather conditions, use a grit distributor (1) mounted on the vehicle itself, ahead of each wheel. The container for the grit (7) can be double walled, and can carry a sliding flap (3) operated from the driving seat to control the discharge of the material. Two containers may be mounted, each positioned ahead of a rear wheel, and may be connected to the engine exhaust pipe so that one contents are heated during the cold weather. The contents can be discharged by a rotary distributor with e.g. distributor blades. The discharge may be controlled in accordance with the speed of the vehicle.
Patent FR-2318802-A1 (FR)
Title: Storage tank with flexible floating roof - has valve controlling air supply to inplatable seal and discharge of contents
IPC: B65D88/48
Filed: 1975-07-25
Abstract: A storage tank (2) has a delivery pipe (5) which is opened by valve (6) operated by a lever (13). At the same time a supply of compressed air travels along an external pipe (12) to pressurise the floating roof (3) and form a seal over the liquid surface. The lever (13) operates simultaneously a delivery valve (6) and an air inlet valve to the supply pipe (12). An air compressor automatically cuts in when he operating lever is moved, so that a single lever movement ensures both the emptying of the tank and the sealing of the liquid surface.

Patent FR-2289853-A1 (FR)
Title: Heating-method for multi-storey buildings - with liquid heat-carrier heated in cycle by second heat-carrier
IPC: F24D3/02
Filed: 1975-10-24
Abstract: In this process for heating buildings, the individual rooms are heated by at least one radiator, through which a heated liquid heat-carrier is passed. This heat-carrier is passed in a cycle through a heat-exchanger (radiator-cycle), in which heat is transferred to the heat-carrier by means of a second heat-carrier, which is heated in a boiler and passed in a cycle between the boiler and the heat-exchanger (boiler-cycle). The two heat-carriers are passed within the range of the heat exchanger at a high relative velocity, preferably in counterflow. The arrangement avoids formation of airlocks in radiation-pipes and can be easily adjusted to the individual heat-requirements of different flats or offices.

Title: Live body cell ionisation appts. - has amplifier with metal conductors insulated from each other
IPC: A61N1/20
Filed: 1975-12-30
Abstract: The apparatus ionises the cells of a live body, having a device applied to the skin and generating the necessary energy by means of one or more electrically conductive metals. This causes the organic energy of the body to close the circuit. An amplifier for the organic energy has metal conductive components separated by insulators. The device applied to the skin can have one or more conductive metal components fixed to it, and electrically insulated from each other. The conductive metal, applied to the skin, of the amplifiere can have a different electrolytic potential to those used in the device. Each of the two amplifier poles can be electrically connected to the pole of an electrical energy controller.

Title: Stabilising gyromagnetic material of garnet type - with zirconia or calcium oxide, reducing prodn. time, cost and resonance line width
Inventor: DESCHAMPS ANDRE
IPC: C04B35/26
Filed: 1975-12-30
Abstract: Gyromagnetic material of the 3M2O3.5N2O3 garnet type (in which M is trivalent lanthanide(s) and N is trivalent metal(s) is obtd. from a non-stoichiometric garnet-forming oxide mixt. contg. ZrO2 and pref. also CaO as stabiliser, the molar deviation from the stoichiometric compsn. being -0.2 to +0.2 and the molar concn. of (each) stabiliser 0.035-0.20. Used in v.h.f. applications. The addn. of the stabiliser limits the number of process stages needed, so that the prodn. time is reduced by 25.30 h and the cost of the prod. is reduced. The gyromagnetic resonance line width is almost the same as that of the pure material. The additive can be used in technical processing and in all garnets, esp. those in which part of the Fe and/or Y is substd.

Title: Jacquard machine lifting blade drive - has separate cam disc drive assembly for each blade to give staggered shed closing action
IPC: D03C13/00
Filed: 1976-01-30
Abstract: The appts. is used to operate the lifting blades of a Jacquard machine, to control the lifters for the warp yarns. Each lifting blade is powered by a separate drive unit. The system gives a precise control over the movement of the warps, so that each warp yarn cam be moved into the closed shed position at a slightly different time from its neighbours to protect the warps and prevent friction damage by contact between warps. The separate drive unit for each lifting blade is composed of a cam disc assembly with a roller lever and a linkage to transmite the motion to the lifting blade. Alternatively, the individual drive can be in the form of meshed gear wheels.

Title: Rotary valve four stroke IC engine - has single rotating concave head valve with port uncovering inlet and exhaust manifolds successively
IPC: F01L7/06
Filed: 1976-06-28
Abstract: The four stroke IC engine has a cylinder head over each cylinder with a slightly dished profile. A valve supported on a central stem matches the profile of the cylinder head and rotates inside it. The valve has a single port through it and as it rotates the port uncovers first the inlet manifold and then the exhaust manifold. This makes it possible for a single valve to be used in each cylinder with a simpler driving mechanism than is necessary for the several reciprocating valves of the conventional type. The valve is cam operated to obtain the correct timing.

The outputs of the first counter's decoder are connected to the second inputs of the comparators. The comparators' outputs are connected to second memories (51-5M) whose outputs feed flip flop memories (61-6M).
Patent FR-2332158-A1 (FR)
IPC: B60T15/16
Filed: 1976-11-19
Abstract: The introduction of the electro-pneumatic brake on European railways cannot be expected for some years yet. It is the object of the invention that the driver's brake valves usual hitherto need only be provided with a few additions in order to control pneumatic and electro-pneumatic brake devices. In this connection, the conversion of a compressed air pulse into an electrical pulse is used for actuation of the braking or release contacts (58, 60) of the electro-pneumatic brake. A solenoid valve device (88), actuatable by the pulse generator (30) by means of the driver's brake lever (14) produces an immediate, time-limited or volume-dependently limited reduction of the pilot pressure. The volume-dependent pressure reduction is achieved by an injection chamber (90), which is connected by the solenoid valve device (88) to a chamber (80) of a pressure sensing switch (56) controlling the pilot pressure. The reduction of the pilot pressure achieved must attain at least the threshold value of the relay valve (40).

Filed: 1977-04-12
Abstract: Prepn. of aromatic amines comprises reacting an aromatic cpd. having >=1 free posn. with hydroxylamine in presence of a redox system comprising conc. H2SO4, an aliphatic carboxylic acid and FeSO4.

In an example, reaction of anisole with NH2OH in presence of FeSO4, 100% acetic acid and 50% H2SO4 gives anisidine with an o=m=p ratio of 29.7:3. 1:67.2. Increasing the H2SO4 concn. to 96% gives an o=m=p ratio of 15:27:58.

Title: Metal powder prodn. - by atomising molten metal stream through pressurised agent jets and collecting droplets in reducing fluid
Inventor: LARSON ULF RUTGER
IPC: B22F9/08
Filed: 1977-07-25
Abstract: Metal powder is produced in an enclosed granulation chamber with a reducing liquid in the lower part and a reducing gas atmosphere filling the upper part. Metal is poured in the molten state and intersected by streams of pressurised atomising agents. The metal particles are chilled in the gas atmosphere and collected in the reducing liquid. This enables a fine-grained product to be produced which has an extremely low oxygen content. The process is much cheaper than one using nitrogen or argon for the atomisation.
