Title: Automatic train safety signalling system - has circuit for providing flashing optical signals in relation to train speed
IPC: B61L29/24
Filed: 1974-05-02
Abstract: The automatic safety signalling system provides optical warning signals at the railway level crossings before the barriers are closed. The switching system for optical signals accommodates different train speeds and it incorporates a timing device. The circuit for providing warning signals in good time before the barriers close has switches with delay elements which have pressure contacts. The tran enters the switching range and the optical warning signal is switched off only on actuation of the disconnecting switch. After the train leaves the switching range then the switches are restored into their initial state for the next switching process. The optical warning signals are given by the lamps which are connected to an alternative action solenoid which causes the lights to flash periodically.

Title: Data text transmission system - has multiplexer decoder selecting data route between memory and main bus and replay address unit for selective switching
Inventor: YING CHARLES W
IPC: G06F3/153
Filed: 1976-03-31
Abstract: The data text transmission system comprises a number of input terminals (10), a central processor unit (CPU) and a number of multiplexers (14) all connected together via a common data bus (16).

Title: Fuel pump regulator for independent vehicle heaters - has electric fuel pump regulated to be proportional to combustion air intake
Inventor: REUTER FRITZ
IPC: B60H1/22
Filed: 1976-05-03
Abstract: The vehicle heating system contains a fuel metering pump to give a fuel feed proportional to the combustion air intake. Battery tension fluctuations causes the air intake fan motor speed to vary and consequently the air intake vol. A regular tension for the capacity diode is gained from the battery connection (32) to alter the oscillator frequency. The oscillator output is fed to an impulse former whose frequencies are reduced by a frequency divider to a ratio of 1; 1000. The static frequency divider output impulses regulate a mono stable switch stage with operation amplifiers whose output impulses have a constant dwell to regulate the metering pump final stage.

Title: Fuel supply system for IC engine - has guide wall in liq. container with narrow apertures to distribute air and lengthen flow path
Inventor: MELLQUIST ALLAN
IPC: F02M25/00
Filed: 1976-07-27
Abstract: The feed mechanism distributes liq. in finely separated form and/or as vapour to an i.c. engine. The liq. is contained in a closed vessel having a distributor in the lower section. The distributor communicates with the external air and has apertures so that this air can reach the liq. in the container. A lead has one end connected to the upper side of the container and its other end connected to the suction pipe of the engine to supply the cylinders with fuel. A guide wall in the container is positioned between the distributor and the lead end. This guides wall has narrow openings to distribute the air and lengthen its flow path. This ensures an effective dampening of the air with the liq.
