Title: Decontamination of nuclear plant components in vacuum chamber - using deionised water sprayed at high pressure and pref. using continuous extraction system
Inventor: DIMITRIJEVIC CEDOMIR DIPL ING
IPC: G21F9/28
Filed: 1977-12-16
Abstract: Radioactive surface contamination is removed from vessels, machine components, etc. by spraying the element, in a chamber contg. no air, with a high-pressure jet of detonate at predetermined temp. and then drying it. The detonate is extracted and collected, while the vacuum in the chamber prevents the escape of radioactive aerosols. Pref. deionised water is used as detonate. An effective cleaning method without the use of pickling chemicals is obtd. depending entirely on physical processes of a thermodynamic nature. The high pressure produces a large number of very small water jets having dimensions of the same order of magnitude as the structural components of the surface. A very high degree of decontamination is achieved.

Patent DE-2802435-A1 (DE)
Inventor: ROTHMAN GYOERGY DIPL ING
IPC: G11B19/28
Filed: 1978-01-20
Abstract: In order to start a disk exactly at a syllable, the turntable (2) must be turned back by a certain angle. For this purpose, use is made of a reversible motor (1), which is coupled to a tacho-generator (3). A central speed control unit (4) controls the motor (1). By activating the actuating member (10), the turning back of the turntable (2) commences at 0.707 of the nominal speed under the effect of a memory (11), an adjusting member (9) and the control unit (4). At the same time, a memory capacitor (13), which is connected to a threshold discriminator (14), is charged. At the end of the acceleration phase, a signal is generated by the discriminator (14), with the result that the motor (1) is driven in the opposite direction, that is to say it is retarded. Then, a braking magnet (20) is actuated, which magnet holds the turntable (2) securely in the desired position. <IMAGE>

Title: Bulk cigarettes handling system - has fixed and swinging rods across container bottom, with rounded pads on fixed rods
Inventor: MENGE GUENTER
IPC: A24C5/354
Filed: 1978-01-26
Abstract: The bulk cigarette handling system for loose cigarettes, with a crank driven reciprocating mechanism for cigarettes inside a container (S) as in the main patent has a line of rods (107) which are reciprocated in an arc above fixed rods (108) side plates (101). Mounted on the ends of the fixed rods are blocks (141) with curved faces, able to rotate freely, to reduce blockage of the cigarettes passing between. The drive for the crank system incorporates a damping device (128) for the upwards movement of the moving rods (107).

Title: Electromagnetically controlled fire-screen door for conveyor - has single magnetic core for both signal controlled exciter coils
Inventor: DETTMANN HORST
IPC: A62C2/24
Filed: 1978-02-20
Abstract: The holding device for a fire protection door for a conveyor has an electromagnetic assembly(4), with two exciter coils. The fire alarm and conveyor monitor is arranged so that release fire alarm signal or monitor clear setting signal, reduces energising only above a threshold, which keeps a closing-plate open. Whe both signal coincide energy passes below this threshold. There is a commonly shared magnetic core for the two exciter coils. The core may be mounted on the closing plate, with an anchor(5) for it on a drive device travelling parallel to the door's direction of movement. This reduces the number of mechanical components and permits precise setting of other structural elements.

Title: Mixer for fire extinguisher foam - feeds main supply line reference and foam agent pipe control signals to controller whose output actuates throttling damper
Inventor: SCHWEINFURTH ERICH DIPL ING
IPC: A62C5/02
Filed: 1978-08-12
Abstract: The control system for foam-producing installations maintains a constant ratio of foam producing agent admixture to water flow. The water is taken from source via suction pipe by pump fitted with bypass in which a Venturi element operates as a mixing unit in the direction of arrow. Water discharged by pump flows through the Venturi element and sucks foam-producing agent from the pipe via a non-return valve. The amount of foam agent added to the water flow is controlled by signals of the throughput measuring instrument in the foam agent line and by signals from a similar measuring instrument in the main foam mixture line. Both signals are fed into controller which emits a control signal to an actuator controlling the operating position of the throttling damper in the foam agent line.

Title: Electrode holder for spark erosion machine tool - gives automatic release of electrode for replacement by pulling baseplate against pins to disengage springs
Inventor: REINKE FRIEDHELM DR ING
IPC: B23H7/26
Filed: 1978-12-14
Abstract: The electrode unit (7, 8) is held against a base plate (5) by clamps (9, 10) which act in conjunction with springs and dowel pins.

Title: Primary PCM bit stream alignment - using extendable buffer store and bit stuffing to align primary PCM for secondary multiplexing
Inventor: BASCHKE REINHARD ING GRAD
IPC: H04J3/07
Filed: 1979-03-03
Abstract: A phase comparator circuit aligns the bit streams of incoming 2.048 Mbit/s prim. systems for multiplexing to the higher order 8.448 Mbit/s. The incoming 2Mbit/s bit streams are counted into a buffer store at N and 2N the prim. bit rate so that the signal can be read out at the writing in rate of the sec. higher order system and the prim. 2 Mbit/s removed. Synchronisation and stuffing bits are also added as reqd. The incoming prim. 2 Mbit/s bit streams are each fed into an extendible buffer store. Each of the four incoming prim. bit streams has a separate store. The writing in pulse generator is supplied with a 2.048 Mbit/s input and delivers 2N so that the pulse width is able to store the incoming bit stream information even though no jitter and line distortions have occurred. Both the output pulse generator and the writing is pulse generator are synchronised to a data selector.
