Title: Leak testing system for large tanks - using compressed gas and electronic computer connected with inner and outer temp sensors
Inventor: SCHMIDL HEINZ
IPC: G01M3/32
Filed: 1979-07-26
Abstract: A method of testing the sealing of large tanks and containers using compressed air involves use of a reference pressure container and a differential pressure container joining the two. It enables the effects of temp., e.g. temp. differences to be eliminated. Sealing faults are thus very accurately and relatively rapidly indicated. Each container has an associated temp. sensor. The temp. signals are input to an electronic computer which compares them and feeds the computed difference values to a printer and digital display as well as using them in pressure computations. The temperature sensors measure both internal and external tank temperature. The computer processes the corresp. signals before performing the differencing operations. The pressurisation is performed using a safety gas if the tank, e.g. an aircraft fuel tank, which has previously been filled with fuel.

Title: Automatic alignment of burner on seam during welding - where periodic reversal of transverse oscillation of burner is controlled by monitoring welding current
IPC: B23K9/127
Filed: 1980-01-16
Abstract: The process is used esp. in inert gas welding, where the burner is oscillated transversely across the seam. The alteration in the welding current (I) produced by the oscillation is continuously monitored and employed to reverse the direction of travel of the burner across the seam. In the pref. process, the welding current rises to a max. when the burner reaches the centreline of the seam and then starts to decrease. The direction of transverse travel of the burner is pref. reversed when a specific, adjustable time has elapsed after the burner has passed over the centreline of the seam. Very narrow welded seams can be produced.

Title: Small farmyard manure gas plant - using hand pump instead of motorised paddle mixer
Inventor: WEBER FRITZ
IPC: C12M1/107
Filed: 1980-02-26
Abstract: The Parent Patent No. 2711146 described a farmyard manure gas plant of small enough size to be suitable for single farms. To make this system independent of any electric power, the paddle mixer in the manure fermentation pit, driven by an electric motor, is now replaced by a hand pump which is built into the pit at an angle and is also used to feed straw, grass and other waste into the pit. This makes the system more suitable for farms in remote localities or in developing countries.

Title: Feeding solids vertically to fluidised bed in gas - from lower sec. bed through diffusor grid
Inventor: MAIWALD ROLF DIPL ING DR
IPC: F23C10/00
Filed: 1980-06-21
Abstract: A main fluidised reaction bed is supplied with solids entrained by gas rising vertically from a lower sec. fluidised bed or other reaction system. The flowing medium contg. the powdered solids passes through a diffusor grid sepg. the two beds and having apertures with a lower converging section and upper diverging section, sepd. by a diffusor throat. The ratio of length to dia. in this throat is selected to prevent undesired downward return of solids, and the main fluidised bed should be at least ten times the height of the divergent section to ensure uniform flow across the grid area. The appts. is also claimed. The entrained solids and the bed materials can react at very high rates in decomposition or redn. processes etc. e.g. producing aluminium oxide from the hydroxide, or barium sulphide from barytes, esp. with solid fuel. The grid is not liable to clogging.

Title: Insulating connector for overhead conductor or trolley wire - has rod insulators with grooved zone limited to region of no contact with current collector
Inventor: HOECKELE MAX
IPC: B60M1/18
Filed: 1980-07-19
Abstract: The parent patent describes a device for making a load-bearing, electrically insulating connection between two lengths of a trolley wire (overhead electrical conductor); the connecting device comprises two parallel glass fibre-reinforced, rod-type plastics insulators fixed to cross-beams, each insulator has a circumferentially grooved sleeve of highly electrically insulating material. Metal skates act as guides, along the lower edge of which current collectors can slide. In this addition, the grooved zone of the sleeve on the rod insulators is restricted to those regions in which the lower face of the plastics rod insulators is higher than the slide track for the current collectors as defined by the lateral skates. Typical uses include a phase insulator or a section insulator. The current collectors do not slide over the grooved lower face of the rod insulators and therefore dirt does not tend to collect in the grooves. The insulators maintain their insulating capability over long periods.
