Title: Floating-roof tank construction system - assembles cover plate pontoons and inflatable seals on supports from baseplate
IPC: E04H7/06
Filed: 1975-04-29
Abstract: The floating-roof tank is constructed by the erection of a number of short steel angle supports (4) on a baseplate (3) after the sidewall (2) has been erected to a given height. The floating roof is formed on the supports by mounting pontoons (5) round a cover plate (6), and inflatable seals (8) are then fixed in position round the outside of the pontoons, compressed air being delivered to them to seal off the gap between the pontoons and sidewall. Air is blown into the chamber formed under the floating roof, so that this rises in a horizontal position to a predetermined level with the aid of a winch rope (14), forming a sufficient working area underneath. The roof is then secured at the higher level by means of a number of supporting columns (18).

Title: Conveyor rail distance adjuster - has clutch in drive mechanism setting rail distance and slide moving independently from drive
IPC: B21D43/05
Filed: 1975-06-09
Abstract: The gear is for adjusting the gap between a pair of conveyor rails of a feeding mechanism serving a transfer press fitted with a pair or guides on which the conveyor rails slide. The conveyor rails are moved towards each other by a driving mechanism in synchronism with the working cyle of the press, in order to transfer workpieces in continuous sequence in combination with the vertical movements of the slides from one operation to the next. For the adjustment of the conveyor rail distance there is a clutch fitted in the driving gear, which makes it possible to adjust the distance in such a way that the slides can move towards each other independently from the drive, while the clutch is disengaged.

Title: Fuel mixture for IC engines - with superheated steam added to vaporised petrol or oil
IPC: F02M25/022
Filed: 1976-05-10
Abstract: The new gas mixture for internal combustion engines is formed by adding water which is transformed to superheated steam by heating the fuel mixture. Engines running on this mixture can operate over a wider range of ignition timing, ignition can occur either before or after top dead centre. This mixture can be used on all engines with conventional carburetors but it cannot be used with engines equipped with fuel injection systems.
