Patent DE-2850020-A1 (DE)
Title: Swirling flow liquid gas separation - by vortex tube with wall tappings for separator vessel
Inventor: MIKA GYOERGY DIPL CHEM ING
IPC: F25J3/06
Filed: 1978-11-17
Abstract: Liquids such as heavy hydrocarbons and/or water are separated from natural gas by introducing the gas stream containing the liq. components continuously into a zone of centrifugal forces and by drawing off at least a part of the separated liq.. The amt. of liq. which has been separated and precipitated is drawn off by a pressure differential between the liq. and the gas side stream which has been generated in the swirling gas flow. This system operates with a high separation efficiency even when the amt. of liq. is small. The capital cost is greatly reduced because of the small overall dimensions of the required centrifugal separator. Even immiscible liq. phases are efficiently separated.

Title: Concreted sewer construction using inflatable rubber form - involves steel strips with ends wrapped round form, with support boards
Inventor: SCHNEIDER HANS
IPC: F16L9/08
Filed: 1978-12-21
Abstract: An inflatable rubber sheath is set on a pre-concreted base, and stretched to prevent change in position. The duct is then made by casting concrete between this and an outer form. The system is used for prodn. of sewers or similar liq. ducts. Steel strips or cable are concreted into the base at intervals, with their ends would round the inflated form. Several support boards are interposed, and interconnected Waterproof concrete is cast in the tower part of the space between the forms. When this is set, the strips are cut through, and concreting is completed. This prevents harmful effects of fluid concrete on the rubber, and it enables provision of a smooth internal duct profile.

Inventor: KUESTER ERICH DIPL CHEM DR
IPC: C07C233/38
Filed: 1979-05-08
Abstract: The invention relates to a process for the preparation of N-substituted acrylamides of the general formula    <IMAGE>  (I) wherein Y denotes a bivalent straight - or branched chain radical with 2 to 30, preferably 2 to 18, and particularly 2 to 6 carbon atom-, preferably a group of the formula (Y1)m-(Y2)n-(Y3)t, in which Y1, Y2 and Y3 each stands for an alkylene group or the radical of a cyclic organic ring system with 5 or 6 carbon atoms, and the sum of m, n, and t is 2 or 3, and R1 denotes hydrogen or the radical of an amine of the formula N(R2) (R3), wherein R2 and R3 stand for alkyl radicals with 1 to 4 carbon atoms, which method is characterized in that dihydracrylic acid amide of the general formula     <IMAGE> (II) is transmitted with amines of the general formula H2N-(Y)-R1 (III) with elimination of ammonia and the resulting N-substituted  beta -carboxylic acid amides are converted into the desired N-substituted acrylamides at elevated temperatures by splitting out of water.

Patent DE-2922645-A1 (DE)
Title: Liquid extractor for nuclear fuel separation - having central rotor with annular passage through which two liquid phases flow in counter-current
Inventor: HENRICH EDMUND DIPL CHEM DR
IPC: B01D11/04
Filed: 1979-06-02
Abstract: Liq. extn process involves contacting a carrier liquid in which is dissolved some required material with a suitable solvent with which the first liq. is immiscible. Mass transfer occurs between the phases, this being enhanced by increasing the interfacial surface area. The equipment consists of a rotor mounted on a vertical axis inside a cylindrical stator to form an annular passage. The heavier liquid is fed in at the top, flowing down the wall and is removed from a branch at the base. The flow is by gravity. The lighter liq. enters at the base and flows up the extractor. The rotor is rotated by a motor and exerts a shearing action on the annular flow passage which creates a rotational action in the liq. films. Used esp. for sepg U and Plutonium. It can be used in conjunction with the Purex process, giving high critical safety while operating at a lower rotational speed than conventional centrifugal extractors. Gives high extn. loads and a high sepn. selectivity.

Title: Signal compensator for magnetic tape recorded TV signals - has amplitude frequency response signals compensated by processing through memory stages and adder
Inventor: HORSTMANN WINFRIED
IPC: G11B5/035
Filed: 1979-12-05
Abstract: A compensation process is designed to handle high speed frequency response variations generated during the replay of coloured television signals that are stored on magnetic tape. Signals from the coils of magnetic pick ups are transmitted over a switch that chanqes state at a rate related to the drum rotation. The signals are passed through a controlled compensator, demodulator and burst isolation stage. The amplitude of the separated colour synchronisation signal is compared with a reference. The difference signal controls integrators and various numbers of switched memory locations coupled to an adder stage.

Title: Arc discharge type overvoltage suppressor for TV receiver - having ferrite electrodes which require no special sealing or protection
Inventor: JAQUET KARL ING GRAD
IPC: H01T1/24
Filed: 1980-01-12
Abstract: A typical application for the proposed overvoltage suppressor is to the HV circuit of the cathode ray tube in a television receiver. The suppressor can also be used for telecommunications equipment. The suppressor comprises two ferrite electrodes (1,2) with suitably shaped ends, contained in an insulation tube (4). The required gap (3) between electrodes is maintained by the electrode fixing in the tube. The use of ferrite eliminates corrosion attach which can affect metallic electrodes used in similar surroundings. Also the ferrite is not affected by arc discharges. The resistance of the ferrite assists both in limiting the discharge current and in damping any oscillations which may arise during the arcing time.

Title: Tunnel tubings hinged joint system - has screws or bolts absorbing sealing pressure, as well as hinges
IPC: E21D11/14
Filed: 1980-03-07
Abstract: The tubular cladding is used in tunnel drive shield units, to form a tunnel ring. Provision is made for hinged connection of tubbing sections in longitudinal joint areas. In these areas (8-13), in addition to the hinge joints, the tubbing (1-5) are connected by screws or bolts.

Patent DE-3101608-A1 (DE)
Title: Mechanical release device for spring brake cylinders
Inventor: HOHN MAX GUENTER DIPL ING
IPC: B60T17/08
Filed: 1981-01-20
Abstract: In a spring brake cylinder, a ball detent which couples the piston rod to the piston can be decoupled by a locking element, which, in the normal position, locks the ball detent, and allows the piston rod to be displaced axially relative to the piston to bring about the mechanical release of the brake. The locking element has a groove which can be brought into radial coincidence with the balls of the ball detent. When decoupling, the balls can penetrate partially into the said groove, thereby being released from a recess formed in the piston neck; the locking element is guided in rotationally fixed but axially displaceable fashion on the piston rod and is acted upon by a release cam which acts on the said element with its control surfaces and can be rotated manually from outside the spring brake cylinder. For this purpose, the release cam is connected to a release element which extends in the opposite direction to the locking element and extends in axially displaceable but rotationally fixed fashion into an actuating part extending out of the end of the spring brake cylinder, such that the release element engages telescope-fashion in the actuating part, which is held rotatably on the end of the spring brake cylinder. To secure the locking element against rotation relative to the piston rod, the said element is guided by means of a guide pin which engages in a guide slot formed on the piston rod and can be displaced in accordance with the axial movement of the locking element in the guide slot. When the locking element is used inside the piston rod, a spring is provided which, extending in the piston rod between the thrust piece of the latter and the locking element, loads the latter continuously towards the release cam.
