Title: Purificn of water - by activated carbon
Inventor: KOMORI MASAKAZU
IPC: C02F1/28
Filed: 1973-02-10
Abstract: Treatment is effected in an adsorption column of multi-stage fluidised beds. The water is treated by stripping it of the unwanted components by adsorbing them on the activated carbon. The latter is discharged from the column to be regenerated and brought backed into circulation for re-use. By the combination of the fluidised beds and the adsorption column, the treatment can be effected at a low cost. The solid materials can flow from the top to the bottom whilst maintaining the beds in a stable state. The used activated carbon is first heated in the fluidised state to 100.700 degrees C., in a desorption chamber, by means of a gas fuel for 5-180 minutes, so as to desorb the moisture and the adsorbate. The carbon is next introduced into an activation chamber and heated indirectly to 500-1000 degrees C by very hot combustion gases, whilst being fluidised by steam, or a gas at a high temp. contg. steam, for 1-180 minutes. The raw water, introduced at the lower part of the column, enters successively into contact with the carbon in the fluidised beds where it is stripped of the undesirable constituents and evacuated in the form of purified water.

Title: Electromagnetic drive with rotating field - having magnetic poles with AC feed to coils with magnetic pickup to give motion
Inventor: GRUHN WOLFGANG
IPC: B01F13/08
Filed: 1974-09-17
Abstract: The movement of liquids, gases, granules, dust particles or other light duty motive requirements is achieved or other light duty motive requirements is achieved by means of a rotating electro-magnetic field. This has a parallel flux outlet and provides the magnetic force necessary to drive various devices. The poles are made from a suitable ferro-magnetic material with coils and can accept single or multi-phase voltages at different frequencies. This field can be used to drive an asynchronous rotor capable of rotating about a magnetic axis on a pivot. Similarly simple flat or curved discs can be used with or without ribs or flights which rotate due to eddy currents and aystersis effect in than and locate themselves in the centre of the field. The device has a very wide range of application. Laboratory magnetic stirrers are known but use a physically rotating field source, with consequent high price, high maintenance requirement, wear on the rotor and lower sensitivity compared with the new device. This can be used as a stirrer in a variety of forms. It can also be used for displays with a floating rotor having no visible drive, for toys and other low duty drive requirements.

Title: Investigation and modelling of electric contact bounce behaviour - uses magnetic pickup equipment andan equivalent model
Inventor: LAUE GUENTER PROF DIPL ING
IPC: G01R31/00
Filed: 1974-12-05
Abstract: The bounce behaviour of electric contacts depends fundamentally on the energy balance in the dynamics of the action, and on the rate of energy loss from that action. An equivalent mechanism is postulated for a double spring contact pair, consisting of two massless contact points (1, 2) each of which is mounted on a massless spring (9) via a suitable mounting arrangement with two further smaller representative springs (7, 8). A typical decaying double sine wave is also provided, which reproduces the motion of the contacts and defines the size and duration of the bounces when the contacts are made. The current through the contacts and the voltage induced in them is used to examine their precise motion. The magnetic field is provided by a horseshoe shaped magnet in the gap of which the contacts are positioned.
