Title: Safety circuit for multiple train model railway - relay cuts off current to track section behind train
Inventor: ARNOLD KURT
IPC: A63H19/24
Filed: 1974-12-07
Abstract: The railway track is divided into sections (1, 2, 3) etc., and the train (4) travels in the direction of the arrow. The transformer (5) supplies current through the regulator (6) through the diodes (7, 8, and 9) and the switches (d3, d1, and d2). When current is supplied to the track section (2) the relay (D2) is energised and opens the switch (d2) and so cuts off the current to the section (3), thus preventing a second train travelling on this section. Similarly as the train (4) moves into section (1), the relay (D1) is energised and opens the switch (d1) cutting off the current to section (2). The circuit can be adapted with additional switches and diodes for tracks with trains running in both directions.

Title: Direction detector for bar coding plate - has photodiodes with output pulses processed without differentiation to avoid ambiguity from noise
Inventor: ROESLER HELMUT
IPC: H03K5/26
Filed: 1975-03-07
Abstract: The direction detector detects the pulses produced from photodiodes as an illuminated bar coding plate passes by and computes the direction of motion. Two samples are taken: the firt (A) is passed to a first trigger (7) and the second (B) to third and fourth triggers (9, 10). The outputs of the triggers are processed by logic circuitry to give difference signals and are used to provide a signal for the counter (15) that tells it in which direction to count. The advantage of this detection circuit lies in determining direction of motion without differentiating the output pulses and the circuit is consequently less sensitive to noise. It may also be produced as a MOS IC.

IPC: B01D9/00
Filed: 1975-06-04
Abstract: Plant for separating substances dissolved in a liquid consists of a chimney type crystalliser having in it a number of suspended heat transfer surfaces, these being hung from a vibrating shuttle arrangement. An air stream is pulled up the passage containing the heat exchanger surfaces and the hot liquid is fed down from the top over them. They can take the form of chains. At the bottom is a system for collecting the liquid draining off the chains, this containing suspended material which has crystallised out during its passage down the column. Some means of conveying this is provided. Plant is for use in recovering acid, esp. H2SO4 from pickling liquid used in the treatment of steel and other metal work pieces for surface preparation. The acid dissolves up metal oxides to form sulphates esp. FeSO4 etc. Because of these salts the liquid can become spent while there is still a lot of free acid in it. The system described gives an economic method for removing water and salts from it so that it can be returned for further use in the pickling baths.
