Title: Mixer for burners operating with compressed air, fuel gas and oxygen - has compensating volumes in the compressed gas supply lines for smoothing the flow
Inventor: GRUETERING CHRISTOPH
IPC: F23N1/08
Filed: 1973-08-11
Abstract: Gas mixer for burner is operated with compressed air, fuel gas and with oxygen and is used esp. in glass moulding machines. The pipelines to the burner have isolating and regulating valves. The compressed air chamber and the low pressure chamber used for oxygen and the low pressure chamber for the fuel gas are connected to adjustable hollow chambers.

Title: Flame cutting burner - with accurate and neat cutting ability
Inventor: RUEBSAMEN ERICH
IPC: B23K37/02
Filed: 1974-01-17
Abstract: An autogenous flame cutting burner is mounted on a carriage which is driven by an oxygen turbine, acting through variable-speed gearing on one of its runner wheels. The oxygen is supplied through a bypass to the oxygen supply line for the burner nozzle which includes a restrictor valve. This achieves a much more uniform speed than is achievable by manual drive of the carriage. The resulting flame cuts are more accurate and neat. The design is less cumbersome than an electromagnetic drive of the carriage.

Title: Length of line analogue display - wiring simplified by two section display alternating at rate to give continuous illumination impression
Inventor: RENNER PETER
IPC: G01R13/40
Filed: 1974-02-20
Abstract: The display unit is for the indication of a measured value as a line of length proportional to the measured value, consisting of a line of light sources which are selectively energised to give a display of the appropriate length. The line of sources is divided into groups of elements, so that for the display of a line of given length it is necessary to light the full groups up to a certain distance from the origin and then the relevant number of member of the last group to give the length of line required. To reduce the complexity of wiring, especially for a remote display, the complete groups and the final part group are illuminated alternately at a high flash rate to give the impression of continuous illumination.

Title: Crane collision prevention system - determines dangerous conditions from difference between vectors representing jib positions
Inventor: DROSTE WERNER DR ING
IPC: B66C15/04
Filed: 1974-08-31
Abstract: The system is for slewing and derricking jib cranes whose working areas overlap, the interval between them being continuously monitored and the dangerous motion stopped when this falls below a preset minimum. To determine the distance between the jibs (B1, B2, C) these are represented as vectors in the diagram of an alternating current system. The difference between the vectors shows the clearance between the jib heads or other components when projected onto a horizontal surface. The position of the other components can be detected by periodically altering the value of the vector representing the jib projection, jib movement being halted when the difference vector falls below a minimum value during alteration.
