Title: High-pressure extrusion of polymers for mfr. of profiles and coatings - by non-plasticising compaction to cause heating-up, followed by pushing into die and softening by abrupt pressure drop, and finally moulding
Inventor: ENGEL THOMAS PAUL
IPC: B29C48/09
Filed: 1978-07-11
Abstract: High-pressure processing of plastics, e.g. for mfr. of tubes, pipes, cable sheathings, comprises compacting a polymer by compressing in a pressure chamber to such an extent that there occurs a rise of temp. without the polymer being plasticised. Treated polymer is shaped about a mandrel, and, by virtue of subsequent compression, forced into a tubular die in which a pressure drop takes place that causes the polymer to be plasticised. Pressure chamber, mandrel and die are designed so that they offer sufficient resistance to the polymer being processed to cause it to be heated up. A shaping tool is connected with the pressure chamber. The mandrel is hollow for installing a heater inside it.

Title: Electroslag remelting of large solid ingots - where axial cooling device lowered into molten metal pool produces fine crystals in middle of ingot
Inventor: DUBINSKIJ RUDOLF S
IPC: C22B9/18
Filed: 1979-05-14
Abstract: One or more electrodes are melted in a chilled mould to form a cast ingot below a molten pool of metal, which is underneath a slag bath. A cooling device is lowered into the metal pool, and is then gradually raised at a speed corresp. with the vertical growth of the ingot up the mould. The cooling device is pref. immersed to max. 60% of the depth of the initial molten pool. Pref. cooling device consists of a float with a density higher than that of the molten slag but lower than the density of the molten metal so the float maintains a desired position during the process. With ingots over 1 m dia. and 2.5 m high, the cooling effect of the mould baseplate is inadequate, so coarse crystals are obtd. in the middle of the ingot. The invention eliminates this problem.

Title: Machine for charging glass tank with pelleted batch - using reciprocable tilted feed table and synchronised closable hopper slit
Inventor: WITTLER FRITZ
IPC: C03B3/00
Filed: 1980-04-30
Abstract: Machine for charging a glass melting tank, having a table extruding over the edge of the tank wall and tilted in the direction of the tank, and reciprocable in the direction of flow of the glass is described. A container which is arranged over the table and locked beneath the table leaves over the whole width of the table a streak of charge, passing through a slit in the bottom of the container, the height of which is adjustable by means of a scraper. Specifically, a closure behind the streak of charge is controlled so that as the forward movement of the table, the slit is closed and when the table returns a new streak of charge is left on the table as the slit is opened. The machine is used when charging the glass melting tank with pelleted batch material, and avoids the difficulty of rolling of pellets down the table, which occurs using the continuous feed machine designed for powder feed, used in prior art, and the excess loading of the furnace due to the rolling of the pellets.

Title: Subscriber-originated cable TV channel selection - using optical fibre signalling links with central broadband couple-field device
Inventor: WELZENBACH MANFRED DR ING
IPC: H04N7/173
Filed: 1980-05-17
Abstract: To enable an entilted receiver of cable t.v programs, or a converence participant in an observer booth, to select the information (or program) required, optical cable lines (1) are used to convey broadband TV and speech signals from various cameras/transmitters to a couple field card (2) for which the enable input lines (12) derive from a microprocessor (11). The outgoing lines (5), which contain the broad band TV signals from those couple points which the microprocessor enables, pass through a participant-individual terminal (4) to the outgoing optical cable lines (3). Each participant has a conference (or subscriber) card entitling him to use any of the services supplied through the broadband cable links (1), and by placing such card into a terminal, the owner's code is transmitted via his line (3) to the terminal (4). A keyboard serves to enter the channel code. Both signals go first into an asynchronous buffer store (7), are scanned by a multiplexer (8), and received by the microprocessor (11). The entitlement data are also held in a store (13) and compared with those offered. The program code is referenced with one of the enable lines (12), and the microprocessor selects the proper couple point to be enabled to pass the desired program to the requesting receiver station.
