Patent DE-2638778-A1 (DE)
Title: Transfer rotor for granulated bulk into pipe line - has exhaust duct for compressed leak air leading out from port above rotor
IPC: B65G53/46
Filed: 1976-08-27
Abstract: A transfer rotor (5) which feeds granulated bulk material into a pressurized pipe line (15), has a vertical overhead supply duct (2) that is offset from the rotor axis. Each chamber of the transfer rotor is filled by the tapered end of the feed nozzle (7) at the bottom end of the supply duct. The compressed air that reaches the filler nozzle housing (14) through the empty rotor chambers, is collected in the ring chamber around the filler nozzle wall (3). The compressed air is then exhausted through a duct (13) which is located above the rotor (5) and next to the supply duct (2).

Title: Road side sound absorbent barrier - has panels with U=shaped throats formed by vertical members secured to adjacent ones
IPC: E01F8/00
Filed: 1976-09-10
Abstract: The sound-absorbent barrier has corrugations on one or more faces, and is particularly for the reduction of noise generated by road traffic. It is designed for installation along motor-ways and their central reservations and also acts as a crash barrier, absorbing shock loads by stretching in the lengthwise direction. It is built up of components alongside and one above each other, each of box-section and with plates held apart by vertical U-section members between, and the space between the plates can be at least partly filled with filler material. To- allow each component to be mounted directly between the adjacent ones without the use of a post etc, each of the vertical panels (1) has a U-shaped throat formed by the vertical members (10, 11). The base of the throat is formed by the body of the member, while the throat slides form arms covering the corresponding ones of adjacent components (5). They are secured to the latter by fixing devices passing through openings in the arms.
Patent DE-2641048-A1 (DE)
Title: Multi-cylinder polytropic IC engine - has volatile liq. injected into cylinder with subsequent heat recovery from exhaust via condenser
Inventor: HUEBNER HANS-JUERGEN ING GRAD
IPC: F01K27/00
Filed: 1976-09-11
Abstract: Liquified gas is injected under high pressure into the cylinder during the expansion stage. This recovers some of the heat by flash evaporation and removes the heat from the hot exhaust gas. The gas mixture so obtained is passed through an expansion turbine and finally enters a condenser. The gas is reliquified and recycled by a gear pump and metering pump. The condenser is fed by a compressed gas, which expands during the condensation process. This drives a further turbine. The expanded gas is recycled and some is fed to an air condenser and is returned as liquid. The combined scheme improves the overall thermal efficiency of work obtained per unit of input fuel.

Title: Magnetic record and replay head - has tracks for video or audio signals and erase facility by use of three adjacent units
Inventor: MUENZNER WULF DIPL ING DR
IPC: G11B5/55
Filed: 1976-11-24
Abstract: The magnetic record/replay/erase head comprises a three unit block (5) mounted on a bearing spindle (6), the tip of which glides over a disc with a spiral shoulder (7). Rotation of the bearing spindle causes the height of the head to be modified. The front face of the head has three pick-up units (8, 9, 10)which may be used in conjunction with an array of parallel magnetic tracks so that read/write/erase may be carried out on audio or video record tracks at the same time. The ability to pick-up and record enables a video tape to have audio signals superimposed on it.

Title: Prepn. of sorbent for extracting toxins from blood - by modifying surface of anion exchanger, active carbon or di:vinylbenzene-styrene! copolymer with blood serum albumin
Inventor: KORSCHAK VASILIJ VLADIMIROVITS
IPC: A61K35/14
Filed: 1977-01-19
Abstract: Prepn. of a sorbent compatible with blood for extracting exo-and endogenous toxins comprises sorbing blood seum albumin on the original sorbent, which is an anion exchanger, active carbon or a copolymer or styrene and divinylbenzene of specific surface at least 20 m2/g, and then carrying out polycondensation at 10-90 degrees C. The sorbents can be removed to extract toxins of exo-or endogenous orgin from blood and other biological media e.g. by haemoperfusion or e.g. in combination with artificial kidneys. The modification of the surface of the sorbent with the high mol. biopolymer by chemical crosslinking increases the blood-compatibility and greatly reduces the destruction of the cells of the biological media on contact with the sorbent.

Title: Flame heating fabrics prior to steaming - as preheating during dye fixing
Inventor: FEESS ERICH DIPL CHEM DR
IPC: D06B21/00
Filed: 1977-09-12
Abstract: Flames are directed on wetted textile prior to its entry to a steaming chamber for dyestuff fixing. The water on the textile is raised to near its b.pt. Condensn. on the fabric during dyeing is avoided. Washing out of the fibre tips is thus reduced, dyed areas have a more distinct outline and residence times in the steamer are reduced. Pref. the flame is produced by gas jets arranged to spread the flame over the whole fabric width. The water in the fabric is raised to within 5 degrees C of b.pt. The water content in the fabric can be =50%. Steaming can be conducted at 102-140 degrees C. Dyeing can be conducted as a one or two phase fixing/dyeing process, e.g. with vat, sulphur or reactive dyes.

Title: crosslinked polyethylene insulated cable mfr - by crosslinking operation after enclosure of insulation in metal sheath
Inventor: ESSER JOSEF DIPL ING
IPC: H01B13/14
Filed: 1978-10-21
Abstract: A cable with a thermoplastic insulation is produced by extruding around a core a not yet crosslinked polyethylene insulation. The extrusion can be done in three stages, with a smoothing layer, an insulating layer proper and a conductive outer layer. A metal sheath is applied to this by spraying or by welding a spiralling metal tape. The originally a little larger inside dia. of the metal sheath is reduced to the outside dia. of the insulation by a drawing operation. After cooling the insulation to give it a higher mechanical strength, the polyethylene is crosslinked in the closed metal sheath, by conventional heating in a steam tube. The insulation cover is thus protected all the time against the ingress of moisture. The result is a very high-class crosslinked polyethylene insulation.
