Title: Multi-purpose aerosol container - chambers for vacuum and compressed gas to maintain pressure on liquid
IPC: B05B9/08
Filed: 1974-02-15
Abstract: An aerosol container which can be used for a number of purposes, has two tubular compartments (I, II), one inside the other, each closed at top and bottom by end pieces and pistons (14, 19). The lower piston (14) is attached to the end of a hollow shaft (13) round which the upper piston (19) slides. Two chambers (A, B) are formed, the upper to hold the pressurised liquid, the other to contain a vacuum. When the container is being filled via the nozzle (12), the upper piston is pushed downwards, creating the vacuum in the lower compartment. The space between the piston is open to atmosphere. During subsequent removal of the pressurised liquid, the vacuum maintains pressure on the upper chamber. A third chamber can contain pressurised air or gas to supplement the vacuum.

Title: Ventilator for dispersing comminuted granular material e.g. corn cobs - has two impellers counter rotating at different speeds
IPC: A01F29/06
Filed: 1974-08-12
Abstract: Ventilator smallest inner impeller blades, throw the material to be treated against the blades of the outer impeller which also serves for further transport of the treated material. Both impellers may be driven arbitrary in opposed or the same direction via a separate drive whose relative speed may be adjusted to achieve the degree of comminuting of the material. The outer impeller has at its outer periphery extra blades which are adjustable in a radial direction. Blades at the inner impeller periphery are adjustable to alter clearance between inner and outer impeller. Inner walls of ventilator casing are ribbed for further comminuting of the material, whilst the outer impeller has extra lateral blades to increase air displacement through the ventilator.

Title: Electronic servo-mechanism for automatic car washer - measures power needed to overcome friction when brushes touch car
Inventor: LERIBLE JEAN-FRANCOIS
IPC: H02P29/00
Filed: 1974-10-15
Abstract: Input circuit applies AC power and brush drive motor current to a multiplier and filter circuit to produce a voltage proportional to the phase shift induced by the motor. The System can be calibrated by closing the switch and comparing the voltage when the brushes are free-running with a calibration voltage, leaving the voltage in the memory when the switch is opened. When brushes touch the car, additional phase shift is induced, and the voltage rises producing a voltage at the output of an adding circuit. This operates a first control circuit. Subsequent control circuits are initiated by the preceding circuit.

Patent FR-2326013-A1 (FR)
Title: Chain nuclear fission power station - converting nuclear energy directly to electrical energy, utilises kinetic energy of fragments
IPC: G21D7/00
Filed: 1975-09-24
Abstract: A power station operating by chain nuclear fission directly converting a part of the nuclear energy to electrical energy, makes use of the kinetic energy of the fission fragments by causing them to overcome a high potential difference. The nuclear fuel is in the form of leaves several microns thick. They are placed inside compartments almost completely closed and designed to recover almost all the electric charges carried by the emitted fission fragments. The potential difference between the leaves and the walls is 1.5-2 MW, and the system is a source of direct current under very high potential. Communicating holes between the compartments give ways for high tension connections and for gases and allow the establishing of a high vacuum. The compartments are arranged in modules connected to a source of vacuum of 10-6-10-7mmHg. A heat transfer fluid flows round to take out and use the heat transmitted to the walls by the impact of the fragments. The heat is used to operate thermal motors and alternators. The overall yield of energy from the installation can be 50% greater than that from existing installations. Thermal pollution is less, the technology is simpler and the cost of building the station is less.

Title: Hydraulically compensated shaft seal - has rubbing ring spring load reacted by ring clamped by grub screws
IPC: F16J15/34
Filed: 1975-10-03
Abstract: One rubbing ring (3) is fixed in rotation in the pump body (6) by a radial pin (5). The other rubbing ring (7) is bonded in the end of a cylindrical sleeve (8) and the rings are held in contact by a spiral compression spring (13) contained in the sleeve. The other abutment for the spring consists of a ring (9) which plugs the end of the sleeve. Grub screws (12) pass through holes in the ring and their conical tips bear on conical indentations (15) on either side of the slit (16) in a slit ring (11). This ring grips the shaft under the action of the screws and retains the assembly in place without weakening the shaft. O-ring seals (18, 19) are provided between the three components and the spring is thus protected from the working fluid.

Title: Extruding double row of ceramic tiles - which are joined by notched webs to permit easy sepn. after baking (NL180576)
IPC: B28B17/00
Filed: 1975-11-13
Abstract: Process for mfg. ceramic bricks or titles, where a ceramic mass is fed through a die plate possessing a cavity corresponding with two tiles joined by webs, and the extruded strand is cut to the desired lengths followed by baking, after which the webs are broken to separate the two tiles. The novelty is that during the drawing or extrusion, at least one groove is formed at the transition zone between the webs and the tiles, to form a low strength region, and force is rapidly applied in two opposite directions, both at 90 degrees to the direction of the webs, so that the latter break in the weak zones formed by the grooves. The pref. device for breaking the webs is included in the claims. Ensures that the webs are broken at their ends so that rough projections do not remain on the titles and interfere with transport or laying.

Title: Protective sheet esp. for towing iceberg through tropics - made by edge-joining of narrower sheets then rolling onto floating drum
Inventor: MOUGIN GEORGES
IPC: E03B3/00
Filed: 1976-08-13
Abstract: Prodn. of a protective sheet or casing of very large dimensions, esp. for platform shaped icebergs, consists of joining together individual sheets of fabric of smaller width. The individual sheets are initially rolled up onto temporary rolls or drums, these are then laid across a working platform, e.g. on the shore, and the sheets are unrolled from them and stitched to welded together along their adjacent edges. The stitching or welding is carried out by operating stations mounted on girders, spanning across the entire width of the sheet to be produced. The finised sheet is then rolled onto a floating drum in the sea and can be transported to the desired place. Used partic. for protecting icebergs to be towed from the southern ocean to desert countries where they are used for freshwater supplies. Process enables very large protective sheets to be produced at any desired location and then towed on their drums to the place where the iceberg is found.

Title: Automatic gyroscope balancing mechanism - has counter-balancing ball which moves radially along rotating diametral slot
IPC: G01C19/50
Filed: 1976-09-03
Abstract: An automatic gyroscope balancing device comprises a ball (19) which may move along a radial path defined by a housing (15) carrying a diametral slot (18). The ball rolls on the shallow riverted conical surface (K) of the gyroscope frame (11a).

Patent FR-2328873-A1 (FR)
Title: C-section support rail for pipework - has slot and hole pattern in web to permit different sizes of fixing screws to be used
IPC: A47B96/14
Filed: 1976-10-18
Abstract: The web (1) of the rail is perforated for fixing screws, the perforations taking the form of longitudinal (2a,2b) and transverse (3a,3b) slots, although circular holes are equally possible, where it is required to fit a rubber grommet for vibration isolation. Different slot widths and hole sizes allow the use of different sized fixing screws according to the duty and in the case of hot water pipes, the correct sized fittings reduce the noise caused by expansion and contraction of the pipes. The faces and edges (5) of the section flanges (4) may be milled so that fixing clamps supporting the pipes can grip more effectively. This also reduces secondary noise effects due to thermal expansions.
