Title: Arrangement for starting and stopping a combustion engine - processes signal from probe and has switch connected to pedal
Inventor: MAURER HELMUT
IPC: F02N11/08
Filed: 1974-08-31
Abstract: The starting and stopping arrangement for engines with a starter motor, consists of a switch which is linked to the gas pedal. The switch can be in two positions depending on the position of the pedal. When the pedal is not depressed, there is a signal potential across the switch, when depressed, there is a signal signal potential. A temperature probe measures the operating temperature of the engine, and the signal from the probe is fed to an amplifier. When the engine cools down, a logic AND unit will process the signal from the probe and the switch connected to the pedal. If the gas pedal is not depressed and the temperature of the engine is above the minimum, the engine will be switched off.
Patent DE-2446968-A1 (DE)
Title: Analysis of low concn. solns - using multiple bundle of sensitive film to increase total sensitivity
Inventor: LUDWIG-CLARIUS WOLFGANG DIPL P
IPC: G01N31/22
Filed: 1974-10-02
Abstract: Transparent test strips are used either as a bundle or in multiple packs in a trough. They consist of an inert carrier substrate film on which is a coating of gel containing reagents and other stabilising agents sensitive to chemicals present in soln. in a liquid. These can be bound with an adhesive, clips or staples at one end or be mounted in slots in a trough. The total change in transparency of colour of all the sheets in the bundle then gives a measure of the concn. of the substance being detected in the soln. and is a single operation. Spacers can be used to prevent the sheets in the bundle sticking together. On the trough, a space is provided below the bundle allowing communication of liquid between the sheets. The measurement can be done by comparing with a standard colour or shade table or by measurement of the change in length or thickness of the bundle. The strips are used for accurate measurement of low concn. chemicals in solns. esp. potassium in blood serum. The use of colour changing film is known, but sensitivity at low concn. is greatly reduced. The accuracy is reduced if a single strip of greater sensitivity is used. The process described provides a simple, straightforward but accurate means of overcoming this problem.
