Title: Automatic filling of a chill mould - from a heated crucible which under press by gravity feed
IPC: B22D39/06
Filed: 1970-09-18
Abstract: The mould is filled from a heated crucible containing molten metal which is placed under pressure so that metal is forced up an inclined feed-pipe to the pouring hole in the top of the chill mould. The metal is thus poured under gravity into the mould giving rise to improved intercrystalline cohesion compared with that obtd. in pressure pouring processes. the feed-pipe may be decompressed so that the metal runs back into the crucible when the mould is full.

Patent FR-2187536-A1 (FR)
IPC: C08L7/00
Filed: 1973-05-30
Abstract: 1386732 Seaming non-metallic sheet material FIRESTONE TIRE & RUBBER CO 1 Feb 1973 [7 June 1972] 5200/73 Heading B5K The edges of two reinforcing cord-fabric plies having a coating of a compound of natural or synthetic rubber which is not vulcanized or cross-linked, the cords of each ply being parallel to each other and to said edges, are butt joined by bringing said edges together with the cords in each ply arranged parallel to the cords in the other ply and subjecting said abutting edges to sonic or ultrasonic vibrations to join the edges without causing cross-linking or vulcanization of the compound. The fabric, e.g. tyre cord fabric, may comprise parallel cords of rayon, nylon, polyester, steel or glass. In splicing apparatus, Fig. 1, a power source (not shown) supplies electrical energy to six converters 11 which change electrical energy into mechanical energy and which are connected to six boosters 12 which increase the magnitude of the mechanical energy. The boosters 12 are connected to separate (ultra)sonic horns 13 which are brought into contact with and apply a predetermined pressure to the plies 40 to be spliced by hydraulic or pneumatic cylinders 14. These plies 40 are supplied by a conveyer belt 20. To ensure that the pressure applied during splicing is uniform, the belt 20 is backed by plates 30 supported by an air bag 31.

Patent FR-2245859-A1 (FR)
Title: Method of lowering engine fuel consumption - involves machining carburettor tube according to engine parameters
IPC: F02M19/08
Filed: 1973-08-23
Abstract: The process to decrease the fuel consumption in an engine with a conventional carburettor consists in machining the carburettor choke tube. This identification is made according to the mathematical formula D=(0.82 x square root CxR) x 106 where D is the carburettor diameter in millimeters, C is each cylinder's volume in cubic centimetres and R is the maximum number of engine revolutions per minute, in thousands of revolutions per minute. Generally and based on experimentation, a widening of the choke-tube by the constant ratio of 0.06 of the original decreases the air's pressure to produce a saving of fuel as less petrol is required during acceleration.

Title: Jet propelled aircraft convertible into helicopter - has jet engine exhaust deflectable to turn rotor with retractable blades
IPC: B64C27/22
Filed: 1974-05-27
Abstract: The aircraft fuselage (1) is surmounted by jet engines (2) with normal jet exhaust pipes (3). Over the engines is a vertical duct (4) into which the gases can be deflected so as to drive a rotor whose blades (6) can be retracted into a support (5) when not in use. Holes (15) around the edge of the support allow the exhaust gases to escape. A small low wing (7) with large ailerons for stability in fixed wing flight and transition is fitted to the fuselage. A casing (8) on the upper surface of the fuselage contains controls, electrical and oil systems, etc. The machine can land and take off vertically, obviating the need for an elaborate undercarriage. No tail rotor is required as the main rotor drive does not transmit torque to the fuselage.

Title: Impact absorbing chassis for lorry - transfers momentum of load into vertical movement by limited movement shock absorbers
Inventor: YAMANAKA AKIRA
IPC: B60R19/00
Filed: 1974-09-05
Abstract: The load surface of the lorry is joined to the chassis by energy absorbing elements with plastic deformation under impact. Wedge supports (6) between the chassis and the load surface interact to lift the load surface when the impact force exceeds a set amount. The upwards movement of the load surface is limited by a first set of stops (75, 76) while the rear of the cab is protected by a second set of stops (8) to prevent the load surface from striking the cab. The rear of the lorry is fitted with a shock absorbing bumper (7) to absorb limited impacts. The system enables loaded lorries to be stopped on impact without the load crushing the cab, and without the momentum of the load increasing the damage on the cab.

Title: Evacuation under sterilization of reusable aspirator vessel - prior to use for drainage of surgical wounds involves using sterilisation heat to expand and force out excess air
Inventor: DEMARMELS MARIO
IPC: A61M1/00
Filed: 1974-12-27
Abstract: The connector on the vacuum-tight-aspirator vessel is provided, prior to sterilization, with a non-return valve (5) in such a manner that the heat of sterilization forces some of the air in the vessel to expand and flow out through the valve resulting in a vacuum in the flask as it cools. Pref. the vessel is heated to 120 deg.-130 deg.C. A nipple (7a) arranged on the inlet side of the valve is inserted into the connector neck whilst the outlet of the valve is threaded (66). With this system there is no danger of germs from a vacuum pump entering the vessel as can occur in evacuation after sterilization and before use.

Title: Heat pump circuit for cooling or heating - has auxiliary section with compressor, expander, condenser and evaporator using additional heat source
IPC: F25B7/00
Filed: 1974-12-31
Abstract: The heat pump circuit is for cooling or heating, running between hot and cold heat sources at a distance appart. A compressor delivers the medium in gaseous form to a condenser exchanging heat with one source, from which once cooled it passes to an expander unit and thence through an evaporator exchanging heat with the other source back to the compressor again. There is also an auxiliary circuit using one of the sources names as a source of primary heat and also a secondary source at a distance from the first two. This circuit also has a compressor, condenser, expander unit and evaporator. The auxiliary condenser exchanges heat with the primary source used or the secondary one and is mounted near the main evaporator when the primary source is the hot heat one.

Title: Joint for conveyor belt transporting powder - has ends of belt extended to form sealing lips to protect hinge pin
IPC: F16G3/04
Filed: 1976-11-30
Abstract: The ends of a conveyor belt (1b) are joined by metal clips (2a, 2b). These clips are U-shaped and with rectangular cut-outs which enable the clips to be fitted together and be secured by a common pin, so that a hinge is formed. When this type of belt joint is used with a conveyor carrying material in the form of fine powder, the grains penetrate the gaps between the hinges and wear away the hinge pins. This defect can be overcome by extending the surfaces of the belt (1b) to form lips (7b) which seal on the rounded surface (4a) of the mating hinge and prevent any grains reaching the hinge pin.

Title: Gas or fluid display system for publicity purposes - uses coloured gas or fluid circulating in shaped tubes forming letters or numbers
IPC: G09F13/24
Filed: 1977-05-13
Abstract: The display system has an enclosure (1) delimited by a wall which presents at least in part a transparent or translucent surface whose shape corresponds to the display. A system is provided for introducing into the enclosure (1) at determined instants and during determined time periods a fluid. the fluid is more impermeable to light than the transparent or translucent wall of the enclosure. thus the display appears darker each time a part of it contains the fluid. The system has devices for introducing two fluids successively and periodically into the enclosure. One of the fluids is transparent for example air, and the other is relatively opaque or coloured, for example a liquid. The system can be designed to permit periodic introduction of a coloured gas into the enclosure. The gas is vented to atmosphere when the disply is to be removed.
