Title: Sewage clarification - in two flock(s) precipitation stages by injecting calcium salt and iron salt in aeration up draught
Inventor: EICHHOLZ GUENTER
IPC: C02F1/52
Filed: 1979-10-30
Abstract: A process for the phosphate precipitation and for the final clarification of sewage in basins or ponds includes a biological treatment by aeration, followed by two separate flocculation stages for a sedimentation of the sludge. In each subsequent stage, air or oxygen injection produces a circulatory flow. In the first stage, a calcium salt is added and in the second an iron salt, preferably by a metered admixture to the updraught produced by the aeration. Outside the mixing zone, the mixture passed through an anti-turbulence zone. This creates favourable conditions for the sedimentation and yields an easily processed sewage sludge. The large flocks make the precipitation more efficient.
Patent DE-2945021-A1 (DE)
Inventor: DOERR KARL-HEINZ DIPL ING
IPC: C01B17/765
Filed: 1979-11-08
Abstract: SO2-containing, hot gases are catalytically converted in part in a first contacting stage. The water and the SO3 formed is removed from the reaction gas. The remaining gas is heated and then supplied to the second contacting stage. The water vapor content in the reaction gas delivered by a first contacting stage corresponds to an H2O/SO3 mole ratio below 1. The reaction gas delivered by the first contacting stage is precooled by an indirect heat exchange to such a temperature that the wall temperatures of the heat exchanger are above the dew point temperature of the reaction gas. The precooled reaction gas entering a condensing stage is contacted in a venturi with cocurrent sulfuric acid of 98.0 to 100% concentration and a temperature of at least 95 DEG  C. The exit temperature of the gas from the condensing stage is maintained at least at 120 DEG  C. The gas rises in a succeeding absorption stage through a packing layer, which is contacted with trickling sulfuric acid having a concentration of 98 to 100% and a temperature of 70 DEG  to 120 DEG C. The dry gas which leaves the absorption stage and has been freed from SO3 is maintained at a temperature which is as high as or slightly higher than the temperature of the acid as it initially contacts the packing in the absorption stage. The sulfuric acid concentration is controlled by a supply of water into the sulfuric acid in the condensing and/or absorption stage.

Title: Shrink article mfr. - by extruding crosslinking distending and cooling the parison
Inventor: SCHMIDTCHEN HANS MARTIN ING GR
IPC: B29C48/90
Filed: 1979-11-08
Abstract: The process is for the mfr. of articles such as shrink tubes, sleeves, caps, etc., from extrudable materials. A parison is first injection-moulded or extruded, then cross linked and is distended while in the crosslinked state. By cooling the distended shaped article it is fixed. Base materials used for the shrink articles are polymers, e.g. polyethylene opt. copolymerised with propylene, which, after grafting crosslinking agents such as organosilanes onto them, are crosslinked under the influence of moisture before or during the shaping of the parison, pref. at 140-180 deg.C. The process permits the mfr. of shrink articles with "elastic memory" without being dependent on the very expensive radiation cross linking.

Patent DE-3015275-A1 (DE)
Inventor: HERKLOTZ HELMUT DIPL ING
IPC: B03C3/68
Filed: 1980-04-21
Abstract: A system for automatically controlling the voltage of an electrostatic filter with respect to its breakdown voltage limit. The detection of secondary voltage breakdowns which occur within a post-breakdown time period after an initial voltage breakdown cause the filter voltage to be lowered to zero value. After a deionizing time period, the filter voltage is gradually raised during a predetermined rise time period until it reaches a new value. The duration of the deionizing time period and the rise time period may be advantageously computed in response to the history of voltage breakdowns, by a microcomputer system.

Title: Tracking arm adjustment to replay underside of disc - has electromagnet using attractive force to lift arm and stylus for replay
Inventor: ALBRECHT PETER ING GRAD
IPC: G11B3/12
Filed: 1980-04-25
Abstract: The diamond stylus tracking arm mechanism is for disc reproduction equipment. Various options use magnetic circuitry to hold the stylus arm in contact with the disc. The stylus (2), with its magnetic cartridge attached, tracks the disc (1) on the underside. The tracking pressure is applied to the arm (5) by passing a control current (Us) through an electromagnet (10) which attracts a ferromagnetic pad (9) on the tracking arm itself. The electromagnet (10) lifts the arm (5) against the spring pressure force (8) which is used to retract the arm from the disc. Various options use an entirely magnetic arm, magnetic circuitry halfway down the arm, or magnetic circuitry located at the end near the stylus unit. The supply (Us) to the electromagnet (10) can be varied according to the tracking pressure to be applied to the disc and also as a control for lifting the arm and retracting it from the disc. The above is applicable to high density storage technique discs which can replay video and sound or sound only as required.

Title: Pile carpeting washing process - having two identical spray suction units to remove unfixed dyestuff
IPC: D06B5/08
Filed: 1980-09-10
Abstract: The freshly dyed and fixed web, partic. of a continuous pile carpeting material, has hot washing fluid directed at the under surface and drawn through by suction. As the fabric continues through the process, a further application of hot water at about 85 deg.C is directed at the under surface, and drawn through by suction applied to the upper surface. The unfixed dyestuff present is therefore fully washed out, so that the material can be dried. The process gives an effective low-energy method of washing dyed floor coverings before a backing has been applied, with a low water consumption. The equipment needed takes little space, and there is no risk that residual unfixed dye will colour the fibres.

Title: Rail brake wagon approach jolt prevention - involves brake release signal on reduction below min. acceptable speed
Inventor: MUELLER HANS-JOACHIM ING GRAD
IPC: B61K7/02
Filed: 1980-09-30
Abstract: The system prevents jolts from wagons, or groups of wagons, running up in rail brake installations. To attain a prescribed correct speed, actual speed is continuously compared with a freely selectable lowest speed, independently of the normal regulating process. In the event of falling below this speed, a release signal is conveyed to the brake. This can be carried out within the rail brakes regulating system, or in a separate independent monitoring position, which can be set up in accordance with fail-safe principles. This prevents wagons from the rear jolting hard against wagons which have been too sharply decelerated or stopped.

Title: Chuck
Inventor: MARSHALL MICHAEL AYRTON
IPC: B23B31/40
Filed: 1981-03-11
Abstract: A chuck which can be expanded in the radial direction has a housing with an open end and a number of chuck segments (12) in the housing (1) which have work-gripping sections (18) which extend in the axial direction through the open end of the housing and are radially displaceable on account of an axial displacement relative to the housing of a supporting part (9). The chuck segments (12) have stops (19) which interact with bearing surfaces (3), extending radially inwards, on the housing (1). The supporting part (9) extends coaxially in the housing and has driver surfaces (10) which are inclined towards the housing axis and interact with radially inner surfaces, arranged complementary thereto, of the segments (12). Here, the relative axial displacement of the housing (1) and the supporting part (9) results in a displacement, directed axially outwards, through the open end (2) of the housing of the work-gripping sections (18) of the segments (12) until the stops (19) of the segments come into engagement with bearing surfaces (3). A further relative displacement of this type by the said driver surfaces (10) results in a displacement of the segments (12) directed radially outwards. <IMAGE>
