Title: Potentiometer and digital voltmeter preselector - reference input to position control uses medium accuracy potentiometer and digital voltmeter
Inventor: CRIPPA AGOSTINO
IPC: G05B19/10
Filed: 1974-09-27
Abstract: A low cost reference input unit for closed loop position controllers utilises a medium accuracy potentiometer. The output of a multi-turn analogue potentiometer is fed to a programming unit and to a selector/display unit. The selector/display unit has a digital voltmeter to provide accurate display of the potentiometer setting. The reference signal is transmitted to a comparator that receives as the other input, the feedback signal from a position transducer. A control block provides outputs for the power drive dependent upon the comparator output and relating to direction of motion and the null position. It is claimed that a low accuracy potentiometer coupled to a single digital voltmeter provides a low cost means of providing reference input.
Patent DE-2448319-A1 (DE)
Title: Bitumen to replace part of binder in boards made of wood chips - esp. as inner laminae of multi-layered construction
Inventor: ERNST KURT CHEM ING
IPC: C08L95/00
Filed: 1974-10-10
Abstract: The boards are normally made in heated hydraulic press using wood chips bound together by 6-12% of their weight of urea-formaldehyde (or- for moisture-resistant boards-phenol-formaldehyde) resin opt. with a fungicide. In a novel process, the resin content will be reduced to 1-4% with the balance made up by bitumen- which has fungicidal as well as adhesive properties. The resin content cannot be eliminated entirely as hot bitumen alone will not hold the board together well enough for it to be removed from the heated press., the strength of the bitumen returns only on cooling. If the boards are to be combined into a laminated form with three or more layers, the outer layers will be of the normal all-resin kind, as these have a better appearance as well as being more resistant to prolonged pressure.

Title: Sewage treatment using power station waste heat - in heated channels with lowered nutrient media carriers
Inventor: BORST ADOLF H
IPC: C02F3/32
Filed: 1975-05-03
Abstract: The treatment of sewage is combined with the utilization of waste heat from nuclear power stations by extracting metallic salts from the effluents by ion exchangers and by pouring into channels. Tubular heaters near the bottom plates, heated by waste heat, raise the temperature to the optimum for fast-growing organisms (algae) which are lowered into the channel on suitable lifting gear. The waste heat, otherwise released to the atmosphere through cooling towers, which causes series environmental pollution, is thereby utilized to good advantage. The capital investment required is much less than for conventional treatment plant requiring the disposal of sludge.

Title: Measuring the length of an electrode inside an electric furnace - by lowering a plummet through it to the unmelted charge beneath
Inventor: LAMPRECHT GEORG
IPC: H05B7/085
Filed: 1975-05-22
Abstract: The procedure, which can be carried out without interrupting the operation of the furnace, depends on the observation that the charge is melted only to a certain depth below the end of the electrode, and that this depth remains fairly constant (at 25 plus or minus 10 cm in the case instanced). The still-unused length of electrode is therefore arrived at by adjustment from the measurement by plummet from a fixed point, through the electrode to a solid bottom; the plummet is composed of short lengths of graphite rod threaded on a PVC-insulated wire and is held in readiness in a tube above the electrode. While a measurement is being made, nitrogen is blown through the electrode 18, to clear the passage and to prevent the emission of carbon monoxide.

Title: Synthetic material injector with worm plasticiser - has filter flushed by force opened and closed back pressure valve
Inventor: SCHENKEL GERHARD PROF DR ING
IPC: B29C45/50
Filed: 1975-06-04
Abstract: An injection moulding machine for synthetic materials with a plasticising and injecting worm arranged axially displaceable in a cylinder in which it is free to rotate, has, at the delivery end of the worm, a filter in the form of a cylindrical sieve through which the plasticised mass flows radially inwards from the outside, When filling of the mould begins with the advance of the worm, a pretensioned spring closes a return flow valve which during the operational sequence, when rotation of the worm starts plasticising, is forced open by the action of the valve spindle. The machine is esp. used for recycling scrap material, and provides a filter with the largest possible working surface without interfering with the axial displacement of the worm. A return flow valve, force operated in both directions, assists the ejection from tim to time of foreign. matter from th system without dismantling the filter.
