Title: Processing household and industrial rubbish - to obtain secondary metals together with non-metallics subsequently further processed into building materials
Inventor: LANDWEHR WALTER
IPC: B03B9/06
Filed: 1973-07-26
Abstract: Household and industrial bulky rubbis is processed, to eliminate it, by stepwise comminution, with sorting into components before the first and after each individual comminution. The sorted components are passed from each sorting station to storage stations common to all sorting stations, and the components in the storage containers are further processed into technically usable products. Preferably metal parts and light components such as lamps, paper, rubber, or plastics are sorted out at the stations. The light components in the containers, if necessary after further comminution, are processed into sound-insulating building materials, if necessary with addition of binder. The non-metallic heavier residues go to massive building materials. No undisposed residue remains.

Title: Metering mixing and dispensing multicomponent quickset cpds. - using cylinder with successive telescopic pistons one for each component
Inventor: JAHN ULRICH W K
IPC: B01F13/00
Filed: 1973-09-14
Abstract: A method of metering in defined proportions and rapidly mixing without entry of air number of components, esp. elastomer printing matls., is as follows the components to be mixed are successively metered into a mixing chamber by suction; after the desired ratio has been obtd., mixing is carried out in this chamber, air being completely excluded; the resultant mixt. is then expelled from the chamber. The device is used for mixing multi-component elastomer moulding cpds. for dental purposes, for making casts in police detection work, for reproducing three dimensional objects in archaeology, art, technology etc. Since the setting times for these mixts. are extremely short, e.g., 30-60 secs., thorough mixing by hand is almost impossible.

Patent DE-2353751-A1 (DE)
Title: Non removable fixture of screw bolts or nuts - has auxiliary screw for parting off after installation
Inventor: REVESZ ANDREAS
IPC: F16B31/02
Filed: 1973-10-26
Abstract: To prevent screws or nuts from being unscrewed after installation, an auxiliary screw head which is only required to transmit the installation torque, is removed. The remaining head fulfils the primary screw function of clamping, but its shape is smooth and round so that it is not possible to apply a torque to unscrew it by conventional tools. The e.g. hexagon headed torque applying tool is initially super-imposed on the set screw or bolt and attached with a tapering section to the top of the screw. When applying sufficient torque, the tapered frangible section severs from the screw to leave a permanently fixed screw in position.
Patent DE-2360049-A1 (DE)
Title: Degreasing textile webs with liquid solvent - solvent extracted by applying suction to the median zone of the web and directing gas jets onto the edges
Inventor: HOLM WILLIAM JARVIS
IPC: D06B9/00
Filed: 1973-12-01
Abstract: A continuous textile web (e.g. jersey knit) has pref. its edges supported by parallel endless needled chains which advance the web beneath nozzles which spray solvent (pref. directly and in a cascade) onto the full width of the web. Excess solvent is extracted from the web as it is advanced by the chains horizontally by applying suction to the median zone of the web through pref. an axial vent in a suction tube arranged beneath the web between the chains, and by directing gas jets onto the upper surface of the edges of the web. Subsequently the web is dried in a hot air chamber. Pref. the gas jets are fed with air/vapour mixture from the hot air chamber. The edges of the web are effectively dried and the gas jets flatten the edges of the web and prevent them from rolling up.

Title: Biological effluent treatment plant - having three chambers with air ejector circulation from the third to second
Inventor: GEISLER HELMUT
IPC: C02F3/12
Filed: 1974-03-11
Abstract: Biological treatment plant for effluent water consists of three underground pits constructed from reinforced concrete. The two latter chambers are formed from a single tank with a portioning wall as shown. These are fed with an air supply which feeds sparge pipe in No. 2 chamber and runs down to an upturned jet in No. 3 chamber. This is located under a stand pipe which runs from the base of No. 3 back into the top of No. 2. The air jet thus acts as an ejector pump for slurry collecting in No. 3 chamber. This pipe rises to about 3m. above the water level in the tanks and its lower end is about 15 m. above the base. Provides a method for complete biological treatment of effluent streams and allows for clear water to be drawn off.

Title: Fine filter with constant decompsn. of filter cake - and compression, dewatering and granulation of sludge
Inventor: HOEHN ALFRED ING GRAD
IPC: B01D29/00
Filed: 1974-05-21
Abstract: Fine filter comprises a tubular filter body in which is mounted a threaded spindle which compacts, dewaters, and discharges the filtered material. Fineness of the filtrate may be determined by plate-type filters, membrane filters, or filters made of ceramics, sintered metal or fused plastics, and filter pressure is increased together with thickness and compsn. of the filter cake. The distance between the cutting edge of the thread and the inner surface of the tubular filter body is equal to the desired thickness of the filter cake. Initial pressure and the initial time-vol. ratio are set to the desired filter throughput by controlling speed of the spindle.

The stencil is made in varying sizes covering the ranges R15 - R50, R50 - R80 and R80 to R120 with the material made from transparent plastic. The different hole diameters are incorporated to enable different drawing instruments to be securely guided by the stencil during drawing operations. The stencil rotates the instrument around the planned centre point without leaving a centre puncture.
Patent DE-2434076-A1 (DE)
Title: Fixing pipe to hydraulic filter - using conical section at inlet which grips pipe like barbed hook
Inventor: ASSMANN WOLFGANG
IPC: B01D27/08
Filed: 1974-07-16
Abstract: Liq. filter has pipe fixed into its housing by means of a conical section construction formed from a lip around the inlet (or outlet) hole so as to project into the filter with reducing dia. Into this is pushed the pipe or tube, being of somewhat greater dia. than the constriction which consequently bites into it giving an adequate seal and prevents its withdrawal by the barbed hook effect. The lip around the opening is circular and is located centrally on the filter axis. The lip is shaped from the filter housing as one piece or as a part of it. The tube pushed into it should be elastic, esp. polyamide. For use with hydraulic installations where often the filter must be connected to the base of an oil reservoir by a line. This allows a good seal to be made without the use of tools or extra sealing matls. merely by pushing in the line.
Patent DE-2434268-A1 (DE)
Title: Tooth brush comprising two parts - has detachable brush insert as snap-in arrangement
Inventor: SIROWATKA BERNT
IPC: A46B7/04
Filed: 1974-07-17
Abstract: The tooth brush consists of two parts. One, a handle which may be of any of the conventional shapes with a fastening arrangement of a clip-in type for the brush section. The brush insert could be made of polystyrol with brush hairs of the usual material. The insert is sufficiently flexible to clip into the handle and can be removed when worn by a pull on the brush hairs. The handle can be made of any of the synthetic materials, e.g. polyamide with suitable properties. All edges should be rounded for handling safely. Advantage claimed is the longer life of the handle is not wasted, savings in raw material and costs.
