Title: Double seated valve operation control system - presses auxiliary valve plate against second main one before opening first
Inventor: BRAEKELMANN WOLFGANG ING GRAD
IPC: B08B9/02
Filed: 1978-04-28
Abstract: The system controls the operating sequence of a double-seated valve with two valve plates movable independently and in relation to each other, one encountering the other after moving for a predetermined stroke and opening it. Before opening the first main valve plate (2) an auxiliary valve plate (10) is brought to bear against the second main one (3).

Title: Ultrasonic dental scaler including vibrator - which comprises magnetostrictive transducer within energising coil, and has acoustic impedance transformer
Inventor: CRANSTON DALE O
IPC: A61C17/20
Filed: 1978-05-26
Abstract: The ultrasonic dental scaler has a handpiece which comprises an outer shell, housing an electromechanical vibrator. The vibrator consists of a magnetostrictive transducer positioned within an energising coil located within the shell, an acoustical impedance transformer connected at one end to the transducer, and a dental work tool connected to the other end of the transformer.

Title: Corona discharge surface treatment of sheet material - esp. of plastic material, using at least one cooled and insulation coated electrode
Inventor: FERRARINI EZIO
IPC: H01T19/00
Filed: 1978-06-03
Abstract: Sheet material is treated by passing it between a pair of corona discharge electrodes one of which is coated with an insulation material and has a cooling fluid flowing through it. Used esp. for corona discharge treatment of plastics film to improve the surface adhesion characteristics. For high prodn. rate the discharge density has to be high, which increases the heat generated in the electrode, and the heat can cause deterioration of the electrode insulation.

Title: Electronic fuel mixt. control for IC engine - has alternative operating modes for cold starting and normal running using delay and revolution matching
Inventor: KOCH HARALD DIPL ING DR
IPC: F02D41/14
Filed: 1978-06-23
Abstract: An exhaust gast analyser provides an input to two amplifiers (2, 3). The first of these (2) gives an output only when the mixture is too rich and the second (3) gives an output only when the analyser has reached its operating temp. The output of the first amplifier (2) passes through a delay (4), revolution matcher (5) and an integrator (6) to a comparator (7). This has an input from a sawtooth generator (8) and its output controls the fuel valve (10). A transistor (11) can short circuit the integrator. It does so when both the analyser (1) and cooling water (13) are below running temp. The comparator then receives a signal from the cooling water temp. and controls the fuel accordingly.
