Patent DE-2346360-A1 (DE)
Title: Mechanical scissor linkage actuator for refuse compacting machine ram - has telescopic sliding members at connection to ram plate
Inventor: MUTSCHLER ERICH
IPC: B30B9/30
Filed: 1973-09-14
Abstract: The refuse compacting press ram plate is actuated by means of one or more scissor linkages. The compacting plate is moved in the vertical direction upwards. The free ends of the scissor linkage are pivoted on horizontally sliding blocks. These blocks slide within the pressure exerting plate. The free ends of the scissor linkage system has freely pivoted rollers. These rolls rotate within the guiding rails between the stops. These guide rails in turn are able to slide freely within the guide rail. The common guide rail ensures that the adjusting rails can slide within it and that they do not project beyond the ram plate. This design ensures that the total stroke of the pressure exerting scissor linkage is not restricted even if a circular pressure pad is used. This refuse compacting press can be used for compacting the refuse in a standard circular refuse bin.

Title: Converting power station wastes into usable materials - fly ash and calcium sulphate mixed to form construction materials
Inventor: HOELTER HEINZ
IPC: C04B7/26
Filed: 1974-01-04
Abstract: Fly ash and other residues obtd. from the flue gas of powder stations, esp. from coal-burning power stations are converted to useful matls. by feeding the dust and ash from the dry separator to a mixer together with the dried and/or calcined residues obtd. from the scrubbing plant used to remove sulphur dioxide from the flue gas; the two materials are fed to the mixer in suitable proportions so that a stone- or brick- granulate is obtd. which can be milled in accordance with the planned end use. In addn. to producing a usable constructional material, the process solves a major disposal problem. The matl. is used as ballast for roads or embankments or aggregates for tarred surfaces or for concrete; by suitable addns. it can be made into a cement type of binder.
Patent DE-2401440-A1 (DE)
Title: Synthetic furniture veneer esp. of impregnated paper - has two-stage drying of resin with intervening embossing stage
Inventor: TERPORTEN HEINZ
IPC: C09J7/35
Filed: 1974-01-12
Abstract: A paste-on facing sheet for wood boards, e.g. for furniture making, is made by impregnating a support sheet with amino-plastics resin, drying with accompanying precondensation of the resin, and imprinting a surface structured pattern. The drying of the resin is first carried out to an oven-dried weight of 4-8% (residual moisture), then the imprint is applied, then drying is completed to below 4%. The brittleness at the imprinting stage is not too high, so that damage does not occur and the imprint is effective. The imprinting pressure is half that normally required. The further drying stage stabilises the imprint, so that it is not weakened when applying the sheet to the board. A lower weight of paper can be used for the support sheet.
Patent DE-2404760-A1 (DE)
Title: Oscillating transistor for UHF TV receiver - in which transistor earth electrode and base are connected together
Inventor: REHM JOSEF
IPC: H03B5/04

Title: Activated sludge removal from ends of sedimentation tanks - using rotary scraper boards
Inventor: KRUEGER HEINZ-GEORG
IPC: B01D21/18
Filed: 1974-04-03
Abstract: Rotary scraper boards for use in elongated sedimentation tanks, to scrape settled sludge, partic. activated sludge, away from the ends of the tank, can be rotated towards the direction of travel of the scraper bridge in the end zones of the tank and are adjustable in the zones and thereby displace the residual sludge directly in front of the sludge suction device. More esp., the boundary as well as the pressure between the scraper boards and the tank bottom can be adjusted without causing increased wear of the board or rubber. Sludge can be completely removed from the ends of the sedimentation tank; the scraper boards are easily removed from the tank, e.g. for inspection.

Patent DE-2424363-A1 (DE)
Title: Coin mechanism esp. for vending machines - has only one current monitor to detect operation of any end stage
IPC: G07F5/22
Filed: 1974-05-20
Abstract: Between a working circuit input and a branch from this circuit to end stage relay contacts, a current sensor is connected which, when energized by current, announces this to the machine control circuit and either resets a machine counter or interrupts the power supply to the machine. The mechanism has pref. six end stages and its design enables it to be connected to an automatic vending machine through an 8-pole plug and socket connector. Within the machine a blocking circuit ensures that only one key can be operated at any one time. The depression of a key closes a magnet for that choice and a monitor relay.

Title: Viscous material filter chamber - with ultrasonic oscillator for filter element in basket
Inventor: HORNBY JOHN ALFRED
IPC: B01D35/02
Filed: 1974-06-05
Abstract: Viscous materials such as chocolate, filler paste, dyes oils or inks are filtered in a closed filter chamber with a filter insert extending over the chamber length from inlet to outlet.
