Title: Open ended cold formed metal container - is directly supported internally and rotated during forming to give uniform wall thickness
IPC: B21D22/14
Filed: 1973-09-24
Abstract: The metal container is initially cold worked and it is processed into its final shape without deterioration of the mechanical properties or of the surface finish. The metal is caused to flow by a force which slightly exceeds the yield point. The process is carried out by using an internal mandrel and an external forming roll. The container material is contacted selectively by a roll during its movement and the cold flow of the material is controlled. The combination of the mandrel and roll act aproximately as deep drawing tools on the container. Complicated shapes can be produced at relatively low costs and at high speeds. The closed end of the container is sandwiched between the rotating surfaces for rotating the container for processing.

Title: Atmospheric air fractionating process - has separate condensation-vaporisation zone receiving oxygen enriched liquid
IPC: F25J3/04
Filed: 1973-11-12
Abstract: Compressed air is cooled by a nitrogen-enriched gas and separated into high- and low-oxygen content liquids in high-pressure columns. The nitrogen-enriched gas is condensed in a condenser-vaporiser by the oxygen-enriched gas. The liquids are introduced respectively into an intermediate zone and the top of the low-pressure column, where they are separated into a nitrogen-rich gas and an oxygen-rich liquid. Part of the oxygen-enriched liquid is delivered to the vaporisation compartment from which oxygen-enriched gas is extracted. Nitrogen-rich gas is delivered to the condensation compartment as a heater, and extracted liquid is delivered to a fractionating zone. During vaporisation heat exchange occurs between nitrogen rich gas and oxygen rich liquid.

Title: Control for automatic gear box - has actuating lever with electric and pneumatic actuator points spaced from control point
IPC: F16H61/02
Filed: 1974-09-26
Abstract: The selection of the appropriate gear for the automatic transmission is determined by the torque, the engine speed and the ehicle speed. These values are measured and transformed into an electric signal which is transmitted to the solenoid (37) which actuates the lever (35) to control the flow of hydraulic fluid through the valve (28) which selects the appropriate gear. In addition, in order to reduce exhaust gas pollution, it is necessary to take the depression in the engine inlet manifold into account through the spring loaded diaphragm actuator (38) which also exerts a load on the lever (35) and so modifies the effect of the electric signal.

Title: Dispensing device for punched cards with photographs - vertical reciprocating rotary bar controls suction head and gripper
IPC: B65H3/08
Filed: 1974-10-09
Abstract: As the bar (5) descends a gripper (10 contacts the top card, and holds it. This operates a microswitch (16) stopping the bar and produces suction through a nozzle (14). At the same time a solenoid (15) attracts a plate (15a) moving the gripper head (10) over towards the solenoid. Fingers underneath the head (10) seize the front edge of the card which curves upwards to meet the suction head. The bar and head, holding the card, then move upwards. A straight groove, with a helical section, machined in the bar contacts a pin in the upper support bearing. This swings the head round 90 deg. and the card is released.

Title: Regeneration heat-exchanger for effluent gas from combustion units - has dimensioned sealing-strips for separating pure from crude gas
IPC: F28D19/04
Filed: 1975-05-23
Abstract: The cylindrical regeneration-chamber, filled with solid material, and inlet and outlet for the heat-exchanging materials perform a continuous relative motion towards one another. The cross-sections of the connections adjoining the front-surfaces of the chamber are sealed off from each other by sealing strips. The sealing-strips on both front-surfaces of the chamber, at the cross-sections, at which the chamber passes from the gas to be heated into the medium to be cooled, is formed so that each sealing-strip extends over a sector-angle of 15 to 30 deg. and a second radial sealing-strip of equal angular width is fixed at a slight angular distance (about 1 to 5 deg). The two strips separate a sector-like sluice-chamber from the main-stream of the heat-exchanger media, to which scavenging gas pipes are connected, into which a regulator element is built on one side of the sealing-element, for regulating the quantity of scavenging gas.

Title: Central heating system using refrigerant - has liquid refrigerant vaporised above saturation pressure
IPC: F25B29/00
Filed: 1975-06-30
Abstract: Heating coils for a refrigerant form a closed circuit, with a heat exchanger for a heat source at a temperature higher than the air around it, where the resistance to flow around the circuit, at least on entry to the heat exchanger, is greater than the saturation pressure at this air temperature, and the liquid refrigerant in the coils is vaporised at a pressure greater than the saturation pressure. Afterwards, vapour at high temperature and pressure is pumped through the coils or condensed so that the latent heat is used for space heating. There is a liquid separator between the heat exchanger and the inlet to the circulating pump so that only vapour enters the pump, and control valves prevent overheating of the refrigerant.

Title: Insulating wall floor or ceiling partition - is of visco electric material sandwiched between plaster, stone or similar material
Inventor: HUET CHRISTIAN
IPC: E04B1/84
Filed: 1975-09-09
Abstract: A partition for use in the building industry, which can be erected either vertically or horizontally and can therefore be used as a wall, floor or ceiling, has improved noise insulation properties and is designed especially to cut down the noise of aircraft, machinery and hammering. It is made of rigid masonry elements which are manufactured from such materials as terra cotta, plaster, stone, ceramic foam, etc., and incorporates at least one internal layer of a visco-elastic materials which is sandwiched between the rigid masonry elements. The layer should preferably be attached to the masonry elements prior to the partition being erected. The layer can be attached in various ways - heat application, adhesive or by projection of the material if it is one which hardens after application. A variety of materials can be chosen for the internal layer, but care should be taken that it gives the maximum energy dispersal possible within the range of frequencies and temperatures occuring where the partition is to be erected.
