Title: Control of fluid mass flow by coriolis flowmeter -  acts on speed of pump to restore desired flow rate after correction of temporary excessive deviation
Inventor: WEBER WERNER DR
IPC: G01F1/84
Filed: 1990-10-15
Abstract: The flowmeter (1) is associated with an electronic convertor (2) feeding data into a computer (3) which digitises the measured actual values and compares successive measurements or gps. of measurements.

Title: Combined supercharger and air conditioner for car - uses compressor on intake air passing to heat exchanger for supercharging and subsequent expansion for air conditioning
IPC: F25B9/00
Filed: 1991-12-24
Abstract: A combined supercharger and air conditioning pump for a car has a compressor driven either from the engine or a separate motor. Ambient air is compressed and flows through a heat exchanger where its temperature is reduced to that of the surroundings. This air is then delivered to the carburettor intake (supercharging only) or to a suitable expansion chamber where it expands isentropically at the highest efficiency possible. During this expansion, its temperature falls even lower and thus can be used for air conditioning. The energy delivered up by the air during expansion can be used for partial supply of the compressor requirement, or in other ways within the car. ADVANTAGE - Inexpensive and efficient combinations of tasks plus an environment-friendly air conditioning medium, i.e. air.
