Title: Toxic waste neutralisation and disposal - using fresh compost
Inventor: HACHENEY WILFRIED DIPL ING
IPC: C05F17/00
Filed: 1972-02-04
Abstract: Waste materials are neutralised by sprinkling, spraying, strewing or vaporising the dissolved, colloidal or slurried toxic waste onto fresh compost. The fresh compost used can be derived from organic waste materials. It is advantageously stacked to a height of 1.8m and after application of the toxic waste to its upper surface, aerated from below. The duration of the neutralisation process depends on the intensity of aeration; petrochemical waste requires 2-6 months, while KCN-contg. residues from the plating industry are neutralised within 6 weeks. The prod. compost in which the toxic waste materials are absorbed, is completely neutral and hygienic and can readily be disposed of; it can be used in agriculture, and the prod. of cyanide neutralisation can be used as a fertiliser.

Title: Leakage detecting pressure responsive disconnecting switch - uses pressure equalising in case of metal bellows leakage actuating switch-off
Inventor: FRANZ FRITZ
IPC: H01H35/26
Filed: 1974-09-10
Abstract: The pressure dependent switch for minimum pressure monitoring is intended for a disconnecting function when a leakage in a pressurised metal bellows takes place. A housing (3), sealed by a packing (4) against the compression spring (2) and against the electric contact assembly (6, 7). This pressure-right housing provides a pressure equalisation when the pressurised metal bellows (5) springs a leak. This pressure equalisation results in the compression spring force exceeding the counter pressure of the metal bellows, which results in actuating an isolating function of the alternating switching contact (7). This arrangement safeguards the operation of delicate measuring mechanisms.

IPC: B31B19/16
Filed: 1974-11-11
Abstract: The machine works by means of moving knives which work against fixed ones and cut out paper from the edges of a continuous flow of paper from rolls, so that the pieces left intact are ready to form the side flaps when the envelope is folded. The moving knives are each made up to two parts and are all operated by a single drive in such a way that the flaps left on the roll between the cuts are ready to form the side flaps of the envelopes. One of the knives can be roated on the axis by which it is driven so as to provide an adjustment for the height of the envelope without having to remove the knives from the machine.
Patent DE-2453996-A1 (DE)
Title: Electronically commutated brushless multipolar DC machine - with current feed at two points only has armature coils connected in series groups
Inventor: SCHADE WALTER DR
IPC: H02K29/00
Filed: 1974-11-14
Abstract: The object is to avoid anti-parallel connection of the switching thyristors in machines with multiple pole pairs thereby avoiding fast rates of change during commutation which may cause spurious firing resulting in supply short circuits. The object is attained by connecting the coils of the drum wound armature such that they form series groups per pole but also form the equivalent of a two pole armature winding. Thus the winding can be fed at only two points 180 deg. electrical spart. The anti-parallel connection inherent in a multipolar machine is thus avoided. The requirement that two electronic switches, on positive and negative sides, shall be on together is still maintained.
Patent DE-2454918-A1 (DE)
Title: Filter for separating blood samples - avoiding use of pipette after centrifuging and reducing chance of contamination
Inventor: SARSTEDT WALTER
IPC: A61B5/15
Filed: 1974-11-20
Abstract: Separation of blood fractions into a more dense, not filterable and a less dense, filterable fraction is assisted by holding the fractions in a cylindrical tube (after centrifuging) and introducing a piston of soft, elastic material with an air tight fit in the wall of the tube. The piston includes a filter and at the top has a narrow neck which widens into a conical opening. Used for making blood serum or plasma samples. The use of a filter instead of a pipette reduces the chance of contaminating the lighter fraction while it is being removed from the tube.
Patent DE-2455777-A1 (DE)
Title: Compression ignition engine feed back system - is exhaust emission colour dependent
Inventor: BERGMANN HORST
IPC: F02B3/06
Filed: 1974-11-26
Abstract: A light source (8) and a photoelectric cell (9) are fitted opposite to each other inside the exhaust system in such a manner that the light source will not become sooted up and the photoelectric cell will turn the light rays received into signals corresponding to the exhaust gas colour. The signals are amplified electronically (11) and fed to an electromagnet (13) whose armature is displaced correspondingly to signal strength to move a regulator slide (15). Should the exhaust gas show a permissable colour, a strong signal is produced by the photoelectric cell and the regulator throttle (5) in the exhaust-inlet connecting channel is held open by oil pressure acting on a servo piston unit (7). An increased exhaust discolouration (rich mixture) produces a correspondingly weaker signal causing the slide valve to take up a position allowing the oil pressure to drop.
