Title: Semiconductor gas sensor - heated to alternate temps. with resistance drop by gas absorption triggering fire alarm
Inventor: TANOUE TADASHI
IPC: G01N27/12
Filed: 1974-07-10
Abstract: A gas detector for use as fire alarm contains a metal-oxide semiconductor gas sensor which is repeatedly heated through an astable multivibrator with transistors to a low temp. of 30-40 degrees C at which it absorbs a gas component (CO), and to a higher temp. of 100-200 degrees C at which it releases the gas. When heated to the lower temp. a resistor is connected in a series with the sensor to indicate by its voltage rise that a reduced sensor resistance has been caused by a gas concn. above a certain threshold. This gas detector requires little electric power; it is simple yet it has a high efficiency. It can readily be set selectively for the detection of gases other than CO and is free from malfunction.

Title: Hydraulically driven concrete pump - has throttle valves between main control valve and operating cylinder of changeover damper
Inventor: SCHLECHT KARL DIPL ING
IPC: F04B9/117
Filed: 1974-08-31
Abstract: An oil pump supplies oil through a main control valve to the pump operating cylinders and also to the damper control valve. It flows from the latter to the two ends of the changeover damper positioning cylinder. The operating cylinders have flanges on the pistons which move a mechanical changeover linkage which operates a changeover valve. This reverses the position of the damper control valve which reverses the movement in the damper positioning cylinder. There are pressure reducing and non return valves between the positioning cylinder and the main control valve and when the positioning cylinder has reversed the flow through these causes the main control valve to change position and reverse the movement in the operating cylinders.

Title: Adjusting process for turbine control valve - is designed esp, for high pressure steam turbine with anticipatory control
Inventor: OBERLE ARTHUR DIPL ING
IPC: F01D17/14
Filed: 1975-05-02
Abstract: The adjusting process is designed for a control valve of a turbine having an anticipatory control particularly a steam turbine working with a high pressure working medium. Pressure control liquid is conveyed to an auxiliary cylinder via a servo control when a setting signal, influencing the position of the control valve, changes. The auxiliary cylinder thereby sets a control valve via a mechanical linkage. Working medium tapped upstream from the control valve operates the main servo piston coupled to the linkage as well as to the control valve to be set. The main servo piston is held until the control valve, blocking the working medium, returns to its original position.
