Patent DE-2404819-A1 (DE)
Title: Reduction of suppression of relevant pulses in pulse-height analyser - involves limitation of dead time to absolutely necessary duration
Inventor: SCHWARTZ PETER DIPL ING
IPC: G01R29/02
Filed: 1974-02-01
Abstract: In pulse-height analysers with real-time analogue-digital transformation, in order to process a pulse, the necessary dead time is required only for the classified amplitude range, and the evaluation and decoding of a pulse is started by the reverse amplitude, which is established by the reverse counting of the analogue-digital converter. The number of reverse counting steps to identify the reverse amplitude is selected in accordance with the maximum amplitude of the pulse. The method also applies to pulse-height analysers in which analogue-digital transformation does not take place in real-time operation.

Title: Ion exchanger water treatment - using clean water side stream for removing residual ions from re-generated exchanger mixt.
Inventor: WANDELT ERWIN
IPC: B01J47/04
Filed: 1974-03-02
Abstract: In an ion exchange treatment of water, cation mixed with anion exchangers are displaced intermittently in a reaction tank in counterflow to the water. The displaced ion exchangers are sepd., regenerated in individual tanks and recombined in a mixing tank. A side stream of the treated water re-washes the mixt. until all residual ions have been removed; the loaded side stream is recycled with the raw water or used for regeneration. This combines simplicity of operation with a low consumption of chemicals without requiring the considerable additional investment required for the residual ion removal operation.

Title: Desk coin operated telephone instrument - has coin testing and cashing-in device, controlled by button operated by user
Inventor: FRANK KARL-HEINZ
IPC: H04M17/02
Filed: 1974-04-08
Abstract: The push-button must be operated as soon as the called subscriber answers. A microswitch generates a cashing-in pulse only when a good coin is inserted, a number is dialled and the push-button is pressed down. This movement is transmitted through a rack-and-pinion system to the cashing-in slide release pin, and closes the microswitch. At the same time the coin moves through a pressure plate into a waiting position. When the cashing-in push-button is released, the coin passes a sensor lever testing it for minimum dia. The sensor lever is deflected and releases a deflector, so that it is placed in cashing-in position. The coil then falls into the coin channel and the microswitch contact is broken.
