Title: Alkaline industrial wastes neutralization - by mixing in tubular reactors with flue gases after sulphur dioxide removal
Inventor: GOETTSCHE REIMER
IPC: C02F1/66
Filed: 1975-04-17
Abstract: Alkaline industrial wastes from the beverages, milk, soap, textile, paper and concrete industry are neutralised by introducing flue gases with a high CO2 content. A compression stage of the gases with part of the effluents removes agreesive acid components (SO2), the part with the precipitate is extracted and the flue gases are mixed in fine distribution with the effluent in a tubular reactor. The intimate contact causes the neutralisation of the industrial wastes by the CO2 content in the flue gases. This removes aggressive components (SO2) which may cause premature destruction of the plant. The system is simple and the effluents can be neutralised to any desired pH-value. The expense for bottled CO2 is saved.

Title: Automatic warning device for agricultural machines - has fault detectors which actuate hooter and shut down engine
Inventor: OBLINGER KARL
IPC: A01D41/127
Filed: 1975-06-05
Abstract: The safety system stops the drive when a fault occurs by means of four control elements (5, 8, 9, 15) inserted in the system. The vehicle speed is reduced by a control lever (2). The control elements (5, 8, 9, 15) consist of an electromagnetic valve (9), a two way valve (8), and a ram (5) with a load regulator (15), governed by the speed lever (2). Supplied with an electrical signal these move the speed lever to the stop position. The time between warning and stop is governed by the regulator (15) and is adjustable. Alternatively the control system consists of a d.c. electromagnet (20) excited by a relay (21) actuated by a warning signal. This also acts on the speed lever (2). There is also audible warning (14), if needed.

Title: Current collector or commutator - for direct or alternating current electrical machines eg. motors, with centrifugally cast lamellae insulation
Inventor: GERMANN ALFRED
IPC: H01R43/06
Filed: 1975-06-20
Abstract: In a current collector for d.c. and a.c. machines, electric motors, having a hub, and a series of mutually spaced commutator lamellae sepd. by insulation, the lamellae together with the hub, form a cage, the interspaces in which are filled with a polymerisable material contg. glass material and capable of being centrifuged, and thereby form a solid unit. Partic. a casting resin contg. glass material is introduced into the interspacing in the cage while this is rotating at high speed, rotation being continued to permit pre-polymn. to start and to bring about hardening of the pre-polymer by action of heat. The current collector or commutator has an above av. strength and improved internal thermal conductivity. Lamellae profiles can be used in which the passages between the lamallae need not necessarily be absolutely parallel. The method of prodn. involves fewer operations and the prodn. costs are significantly less.

Title: Tension regulating system for web of wound material - uses prod. of material tension and winding radius to activate brake on winding off roller
Inventor: SANNER WILLY DIPL ING DR
IPC: B65H23/18
Filed: 1976-07-29
Abstract: Procedure for regulating tension of material in a winding equipment in which a band of material is run between a winding-off roller and a winding-on roller by means of tensioning roller arrangement. The run of the band material between the winding-off and winding-on rollers (8, 3) and the radius (R) of the winding (1) on the winding on roller (3) is continuously measured and the measured values multiplied.
