Patent DE-2104675-A1 (DE)
Title: Framed filter pack - impervious to dust particles
IPC: B01D46/52
Filed: 1971-02-02
Abstract: Folded filter pack is sealed in a dust-tight fashion by a peripheral frame separated from the filter fleece by spacers running perpendicularly to the plane of the peripheral frame. The uniform intervening space is then filled with a foamed plastics material on a mould in a continuous manner and in thin layers around a vertical centre line by turning the mould. The finished filter pack is partic. useful where complete removal of particles to be filtered is necessary, e.g. in the removal of radioactive particles from air, and the filtered air does not exhibit a Tyndall cone.

Title: Hydraulically operated control absorber system - - for pressurised water reactor
Inventor: KUMPF HERMANN DIPL-ING
IPC: G21C7/16
Filed: 1971-09-29
Abstract: Reactor control system applicable to pressurised water reactors in which the absorber elements are located in guide channels within the fuel elements. Upper guide tubes coincident with the channels connect to a pressure chamber through solenoid operated valves. The chamber is maintained at a pressure of 1 to 2 atm. below the reactor vessel pressure by a pump. Energising the solenoid valves opens the chamber to the reactor vessel and the differential pressure across the absorber causes it to rise with coolant flowing through the channel. Rod position is indicated by electro-magnetic or electro-hydraulic systems. A pressure head tank applies excess pressure to the chamber for emergency shutdown.

The action ensures that the nozzles are kept free, any blocking material being pushed back into the furnace interior. The system is intended for furnaces for the reduction of iron oxides and iron ores.
Patent DE-2204133-A1 (DE)
Title: Raschel knitting with double needle bed machine - for making sacks with pattern chain saving
IPC: D04B27/26
Filed: 1972-01-28
Abstract: A pattern attachment for a warp knitting or Raschel loom saves having a long pattern chain. Each bar has an auxiliary bar, worked by a pattern chain, whose highest link is no higher than the link of the main bar. At a time determined by a block, a catch is pulled dis-connecting the main bar for the auxiliary bar. This means the main bar carries on knitting the seam of the sack on the double needle bed machine.

Title: Pneumatic valve controlled by pressure gas - cylinder with at least two pistons connected by piston rod
Inventor: HILLENBRAND ALFRED
IPC: F16K17/20
Filed: 1973-07-23
Abstract: The valve is intended for use in a gas pressure control device with remote cable operation. The valve has simple construction and interrups gas flow when a specified pressure is exceeded. This prevents damage to the rest of the system. If pressure falls below an adjustable lower limit, the gas flow orifice is expanded. One piston moves to and fro acting as control piston. The cylinder in which it runs is in series with the gas inlet. There is a further inlet between the control piston and the other piston which is connected to it. This additional inlet is opened when the pressure falls below the limit. The second piston has a device that applies datum pressure to the control piston. This device consists of a threaded shell holding a spiral spring.

Title: Resonant polyphase static converter - has auxiliary thyristor starter bridge with branches input SCR and output converter
Inventor: NESTLER JOHANNES DIPL ING
IPC: H02M7/517
Filed: 1973-12-18
Abstract: The resonant poly phase static converter for hysteresis drive motors for centrifuges consists, in its three-phase form, of an input thyristor rectifier coupled over a smoothing choke and auxiliary thyristor bridge, to the output converter that supplies the three-phase lines. In general the number of branches in the auxiliary thyristor bridge is equal to n-1, n being the number of phases so that in the circuit described there are two. During the first oscillation period the auxiliary thyristors are ignited instead of the output converter thyristors. The junction between the two thyristors in each branch of the auxiliary bridge is coupled over a capacitor to one of the output phase lines.

Title: Multi-system circular knitter pattern control - uses number of auxiliary control cams to determine zero setting of jacquard pattern drums
Inventor: SCHIEBEL ALFRED
IPC: D04B15/74
Filed: 1974-03-12
Abstract: The control mechanism to determine the needle drive in a multi-system circular knitter, according to the instructions from a Jacquard pattern drum, has auxiliary control cams which are operated in sequence, with a switch unit to mark the start of the pattern drum action which is tripped according to the setting of the control gams. The system provides a simple process to establish a zero setting for the pattern drums to eliminate the risk of false pattern signals being passed to the needle operating mechanism.
Patent DE-2417239-A1 (DE)
Title: Adjustable axle for road or rail vehicle - has chassis height altered by ramp compressed axle springs
Inventor: HARTUNG HEINZ
IPC: B61B13/04
Filed: 1974-04-09
Abstract: The vehicles move over special tracks, where the road-conditioned spring of a universal vehicle is forcibly compressed. The compression is via roller guides on either side, which run in the rails. The compression is effected by the ascent of the running rail, on which the wheel moves. When the correction spindle is screwed into a threaded section on the wheel fork, a conversion to mono rail operation takes place. For a special mono rail vehicle, a control track section is located at the end of the platform. Control track and special track have a conductor rail in the upper part of the direction rail, to transmit current onto an upper or lower current-take off, thereby rotating motor and spindle to the right or left, which raises or lowers the chassis.

Title: Scooping off floating matter, esp. from ind. effluents - walls enclosing buckets close in releasing water, retaining solids
Inventor: GERLACH GUENTER
IPC: B01D21/24
Filed: 1974-07-20
Abstract: Floating matter is skimmed off the surface of fluids, esp. contaminated water in reservoirs from industrial, such as sugar beet processing plants, by a chain of scoops working on the side zones of the surfaces of the fluids on which there if floating matter. The scoops or cages are enclosed by side walls the dimensions of which allow the escape of water at the surface whilst retaining the floating matter, and diminish progressively as they are lifted so that no fluid at all, or very little, remains with the solids. The openings for the escaping water cannot become blocked, and all the fluid is left behind in the container.

Title: Safety brake for motorised trolley - with operating towbar folding when striking obstruction and operation brake
Inventor: ALBER HELMUT
IPC: B62D1/12
Filed: 1974-10-08
Abstract: The motorised trolley is fitted with a tow bar by means of which a pedestrian controls the trolley drive and steering. The bar is hinged in the middle (8) as well as being pivotted on the trolley about a transverse axis. If the trolley overruns the operator, or pins him against a wall, the towbar folds and operates a safety microswitch to switch off the drive, or even to reverse the drive. The folding movement is simple to arrange and provide a large amount of movement to operate the switch. It has less moving parts than a telescopic towbar, which can easily jam.

Title: Binary signal train keying ratio - method detects whether train exceeds or falls short of set keying ratio
Inventor: HEGELER WILHELM DIPL PHYS
IPC: H04L1/20
Filed: 1974-10-17
Abstract: A mean value with respect to time is produced for an input signal keying ratio. The input signal so controls the forward-backward input of a counter with an overflow blocking device, and a frequency switch switching between two timing frequencies (f1, f2), that during presence of pulses the counter counts in one direction, and also the timing frequency is applied to its clock input, while during spacings between pulses the counter counts in the opposite direction and the frequency (f2) is applied to its clock input. The ratio of the two frequencies (f1, f2) is the reciprocal of the set keying ratio. Information on the counter leading bit, which changes its state when the set keying ratio is exceeded, or not reached, is collected from the counter output.
