Title: Oil well-head fire extinguisher - uses a remote controlled tracked vehicle to deliver an inert extinguishing gas e.g. carbon di:oxide
Inventor: AX WILHELM
IPC: E21B35/00
Filed: 1991-03-18
Abstract: Extinguishing oil well or natural gas head fires uses means whereby oxygen is removed from the flame head, thereby snuffing out the flame. A pipe is positoned over the source of the flame, and of sufficient dia. so that an oil spray cannot form on its walls. The pipe is positioned by a remote controlled tracked vehicle, i.e., a tank. The barrel of the tank serves to feed an inert gas, e.g, carbon dioxide, to the pipe. the inert gas is fed under pressure and creates an oxygen free zone around the core of the flame, thus snuffing out the flame. ADVANTAGE - Quicker, more reliable and economical method of extinguishing fires occurring in oil wells, where oil is escaping in an uncontrolled manner.

Title: Electric braking system for two motor battery powered vehicle - has tachometer or battery current sensor and logic selection of regenerative or resistive braking depending on vehicle speed
Inventor: PUESCHEL SIEGFRIED DIPL ING
IPC: B60L15/20
Filed: 1991-11-30
Abstract: A method of electric braking for battery (22) vehicles, fitted with two thyristor (21) controlled DC traction motors (1,7) and (2,6) connected in parallel, is designed to limit the effect of heat generating ohmic losses in the motor windings caused by baking action.
