Title: Petrol consumption calculator for road vehicle - has digital counters recording fuel flow and distance covered for determination of consumption per 100 Km
IPC: G01F9/00
Filed: 1977-08-03
Abstract: The petrol consumption calculator allows instantaneous calculations of the petrol consumed by a vehicle carburettor. One counter records the signal produced by a pickup attached to the pump of the carburettor. A second counter records the signal produced by a magnetic pickup sensing the distance travelled by the vehicle. This second counter produces an output when it reaches a preset level - representing for example 100 m travelled. When the second counter produces its output, the first counter produces an output to display the amount of petrol consumed. This indicates the petrol consumed per 100 km. The device is then reset to zero.

Title: Anti-pollution device used when charging preformed ingots into furnace - comprises a box closing the charge opening of the furnace
IPC: C10B31/10
Filed: 1978-02-09
Abstract: An anti-pollution device for preventing emissions into the atmos. during the charging of chamber furnaces with preformed ingots of materials emitting polluting gases during entry into the chamber, consists of a box closing the charging opening by means of a joint on the walls of the ingot being charged. The box creates a space for collecting the gases produced and channelling them to a discharge arrangement maintaining the enclosure under reduced press. Problems associated with the inflow of a large amt. of air and with the use of systems using movable covers closing the free section of the end of the upper channel are avoided. The deivce allows all polluting emissions to be prevented by channelling the gases into a closed space of shape and size such that they are sent towards the upper collector channel of the chamber without significant loss of pressure and without large quantities of air entering and reducing the efficiency of the suction system.
