Title: Isolation amplifier for video signal switching network - has complementary push-pull output transistors driven by complementary input transistors
Inventor: RALL BERNHARD DIPL ING
IPC: H03F3/18
Filed: 1976-10-14
Abstract: The transistor isolation amplifier, for video signal switching networks has low loss, no dc offset and is relatively linear. Two complementary output transistors in common collector configuration form a pushpull output stage. Each output transistor is driven by complementary input transistor in a common collector configuration. The bases of the input transistors are connected together to form a common input. The output is taken via a filter from the junction between the output transistors emitters. The collectors of the input transistors may be connected directly to the output transistors emitters or-to improve linearity - via resistors.

Title: Mobile installation for mfr. of plastics foam building components - comprises supply tank, flexible pipeline and compressor
IPC: E04G21/04
Filed: 1976-10-20
Abstract: The mobile installation comprises a supply tank; a flexible pipeline; and a pneumatic pressure generator such as a compressor, for forcing the plastics through, and out of, the pipeline. The compressor forces foamed plastics particles e.g. polystyrene beads, from the tank, through the pipeline to a spray nozzle which is provided with nozzles for spraying adhesive on the plastics particles. The installation is usable in any weather and temp. conditions as may occur on building sites. The plastics is delivered to the actual point of application in dry state (i.e. as beads), coming into contact with a liq. viz. the adhesive, only at the last moment of application. This dispenses with the use temp. sensitive liq. reactants.

Title: Activating tank in sewage purification plant - has sludge mover suspended from bridge partly propelled by screw
Inventor: POERSCH RUDOLF DIPL ING
IPC: C02F3/22
Filed: 1976-10-27
Abstract: An activating tank for a sewage installation with at least one aerator for introducing oxygen into the mixture of sludge and water, is equipped with sludge moving arrangements. The scraper or vane is fixed to a driven bridge, and on the bridge there is agitating equipment, for pref. a propeller. The direction of flow from the propeller is opposite to that in which the bridge is driven. The agitator is assembled on the bridge close to the tank wall. In the bottom of the tank there is a collector, pref. in the form of a funnel-shaped recess with drain connections, positioned in the path of the sludge moving equipment. The sludge moving equipment may work by suction and lift the sediment to the bridge which rotates on the centre point of the tank. Provides an activating tank in a system without a presettling tank, in which the deposits of sludge can be removed without putting the installation out of action. The amt. of oxygen put in can thus be calculated with regard only to the activated flocks, ignoring the deposits on the tank bottom.

Title: Microfilm reader system with revolving turret - has two lenses for high magnification of projected image
Inventor: GERNHARDT WOLFRAM ING GRAD
IPC: G03B21/11
Filed: 1976-11-06
Abstract: A microfilm reader has a lens turret which hovers over the film plate such that it has a constant distance from the microfilm. This distance can be adjusted with precision with the help of the focussing knob if required. A horizontal plate which can move against a point is fixed to the equipment. There is a cover glass plate and lower glass plate which encases the film, and can be adjusted as a single unit. By using a handle, first or second lens mounted on the turrent can be brought into play within the optical aixs of the system. An eccentric rod parallel to the handle is housed in a block which has a focussing knob at its end. The hollow rod connected to shaft has a nut in the hollow shell which moves by rotating the shaft. This causes the turret to move up or down relative to the position of the plate.

Title: Saw frame guide for parallel wood cutting - has guide elements set to reach position just ahead of blades
Inventor: PACHZELT SIEGFRIED DIPL ING
IPC: B27B3/02
Filed: 1976-12-07
Abstract: The guideway on a saw frame is for wood being cut lengthways, sawn parallel on at least two sides. Two guide plates, rollers or other elements on the input side engage sawn surfaces parallel to the cutting plane. The guide elements (7) are fixed in a selected setting relative to the saw blades (5), during the sawing process, and they extend to a point directly in front of the blades. The guide elements can be displaceably led on a guide rail (9) aligned transversely to the saw blades, to be movable independently of each other. Screw spindles can be provided for their adjustment. This layout permits precise lengthways cutting of long or square timbers parallel to the two surfaces already sawn.

Title: Silicon nitride-contg. refractories with low permeability - prepd. by reaction sintering ferrosilicon nitride and silicon powders
Inventor: LEVKOV BLAGOJE DR ING
IPC: C04B35/591
Filed: 1977-01-15
Abstract: Porous, reaction-sintered, moulded bodies based on silicone nitride are made by nitriding silicon metal particles and additives and then sintering. The starting materials comprise 70-95 pts. wt. ferrosilicon nitride powder and 30-5 pts. wt. silicon metal powder. Pref. the ferrosilicon nitride contains 65-80 (70-80) wt.% silicon nitride and the rest is essentially free iron. The nitriding is performed at max. temp. of 1350 degrees C (1250-1350 degrees C) and the sintering at about 1500 degrees C for 4-8 hrs. Used as a refractory, the material combines a high porosity, and therefore a low heat conductivity, with a low permeability, and therefore a good corrosion resistance, to gases, slags and molten metals. The material can be produced without pressurised sintering.
Patent DE-2703279-A1 (DE)
Inventor: NOLTE KARL-HEINZ
IPC: G21F9/24
Filed: 1977-01-27
Abstract: The apparatus for conveying casks intended for final storage in an underground cavern and filled with radioactive waste has a loading device which is arranged on the surface and feeds the containers via a continuously or periodically working transport path to the skip, which has a lateral loading opening adapted to the containers. In order to reduce the time required for manipulating the container to be put into the skip, the loading device (3) for the skip (2) is designed as a roller table (8) with driven rollers (7), and the loading surface in the skip (2) is formed by rollers (11). The roller table (8) extends up to the loading opening (10) of the skip (2) and can be put down or lowered automatically into the plane of the rollers (11) of the skip (2) by means of magnetic switch and drive. This enables the skip to be loaded in a fully automated manner and enables the loading device to be accommodated in a radiation-proof space. <IMAGE>

Title: Aircraft landing wheels pre-rotator - has aerodynamic projections sliding in radial wheel channels and biassed by springs
Inventor: WEBER HANS-DIETER
IPC: B64C25/40
Filed: 1977-03-15
Abstract: The device for pre-rotating aircraft landing wheels comprises two or more aerodynamic projections (2) carried radially, movably in channels formed in wheel spokes. The obstructions slide on guide rails (3) in the channel sides. The guide rails slope relative to spoke thickness so that the obstructions are progressively withdrawn into the spokes as they move outwards. The centrifugal force causing this movement is opposed by a spring (4) so that it is arrested when the wheels are turning at the right speed.

Title: Radio receiver for Doppler navigation systems - has individual emitters of antenna line switched first in one direction and then in other or in one direction only
Inventor: BARTON PAUL
IPC: G01S1/40
Filed: 1977-10-27
Abstract: The radio receiver contains a circuit to decode the Doppler signals. It has a wide-band Doppler filter. A second circuit determines the starting and finishing times of the switching cycles. A third circuit determines the Doppler frequency during each cycle. A control circuit controls the operating time of the third circuit, so that it begins to work a certain time after the start of the switching cycle. This time encompasses at least part of the transient time of the Doppler filter. The trend of the filter suppression curve is such that a distinction can be made between the direct signal and a signal generated by multi-path diffusion, when there is a min. angular separation between the signals.
