Patent DE-2849187-A1 (DE)
Title: Tubular reactor with agitator moving along axis - having element mounted on threaded shaft which moves up or down depending on direction of rotation with single shaft seal at top
Inventor: VETTER HEINZ DR
IPC: C08F2/00
Filed: 1978-11-13
Abstract: Self cleaning tubular reactor has an agitator element which can move up and down parallel to the reactor axis. This fills the greater part of the reactor cross section with only narrow clearances with the walls and serves to remove any deposits. The mixing element has a central threaded hole which fits onto the shaft which has a matching thread. The reactor is for viscous liquids and as the shaft is rotated in one direction the element tends to rise. It falls when the shaft is reversed. The only seal is on the rotating shaft. Used for carrying out polymerisation reactions. The basic principle is known of using a disc which moves up and down but the system described uses only a singly rotating shaft on which to seal. This reduces escape of reactants and of lubricating oil into the reactor.

Title: Laser cutting of slots in stamping tools - where movement of tool is synchronised with movement of laser beam so slots can be obtd. in accurate positions
Inventor: ROEDER WALTER
IPC: B23K26/082
Filed: 1979-03-08
Abstract: On a machine frame is a trolley which can be driven in two horizontal coordinate directions (X, Y) at 9 degrees to each other and a laser is mounted on the trolley. On the underside of the trolley are two arms projecting vertically downwards and employed to provide bearings for a horizontal shaft, on which a hollow, cylindrical drum (5) is mounted. Slots are to be cut by the laser in the periphery of drum (5); and steel strips forming circular stamping knives will subsequently be inserted on the slots. On the shaft is a gearwheel which meshes with the teech on a stationary rack, so drum (5) is rotated when the trolley is driven in one direction along the frame. The dia of the gearwheel coincides with the pitch circle which will be formed by the cutting edges of the circular knives. Used in the mfr. of roller knives employed to cut profiles in cardboard used for folding or collapsible cardboard boxes.

Title: Plug connector with safety latch - has plug contact protected by locked cap against touch
Inventor: BONIEK KLAUS ING GRAD
IPC: H01R13/453
Filed: 1979-12-06
Abstract: A protective cap is provided to safeguard the plug contact against dangerous touch. On insulation into a plug socket, the cap is automatically delatched and retracted. On the other hand, on retracting from the socket, the cap moves automatically forward into the protective position and is latched there. Preferably the cap is fitted with locking fingers, which are pressed outwards for better latching by a soring. The latching mechanism may be fitted with several such locking fingers, in order to prevent delatching by hand, without plugging-in into a socket. Thus the mechanism provides enhanced protection against dangerous touch.
Patent DE-2950066-A1 (DE)
Inventor: SCHWARZ DIETER DIPL ING
IPC: G10L13/06
Filed: 1979-12-13
Abstract: An analogue signal, such as a speech signal, is encoded by a delta modulation encoder 3 and stored in a digital memory 5, or is decoded by a delta modulation decoder from the store 5. The speed at which the bits are produced by an encoder 3 and read into the memory 5 or read out of the store 5 and decoded by the decoder is controlled by the instantaneous value of a characteristic quantity of the analogue signal or the associated binary coded signal. The characteristic quantity may be the binary pattern which is produced by a limited number of successive bits of the encoded or read-out signal. It is thus possible to reduce the memory space required for a given length of signal to be reproduced with a given quality. <IMAGE>

IPC: H01B3/30
Filed: 1980-06-10
Abstract: The invention relates to a method for the preparation of highly heat-resistant relief structures with a base of polymers of heterocyclic structure by applying radiation-sensitive soluble polymer precursor stages in the form of a film or foil to a substrate, irradiating the film or foil through negative patterns with actinic light or by deflecting a light, electron or ion beam, removing the non-irradiated film or foil portions and, optionally, by subsequent annealing, as well as to the use of relief structures prepared in this manner. It is provided to use as polymer precursor stages addition products of cyclic carboxylic-acid anhydrides with hydroxyl group-containing compounds, where the hydroxyl group-containing compounds represent addition products of olefinically unsaturated mono-epoxides on carboxyl group-containing prepolymers of polyimides, polyisoindoloquinazoline diones, polyoxazine diones and polyquinazoline diones or on amino group-containing prepolymers of polyimidazoles and polyimidazopyrrolones or on hydroxyl group-containing prepolymers of polyoxazoles.

Title: Coolant nozzle assembly - for sec. cooling zone of guide and support roll track for cast steel billets or slabs in continuous casting plant
Inventor: STREUBEL HANS
IPC: B22D11/124
Filed: 1980-10-18
Abstract: Between adjacent rolls in the sec. cooling zone are at least two coolant spraying nozzles, which are located on coolant supply pipes mounted on holders. The holders are located on a pair of levers joined by a push rod, so the movement of one lever in one direction causes the other lever to move in the opposite direction. The two holders are connected by a guide rod located in a protective telescopic tube. One of the holders is moved by a third lever actuated by an adjusting spindle; and the overall result is that the distance between the spraying nozzles can be adjusted to match the width of the slab or billet being cast. Simple adjustment of the coolant spraying nozzles.

Patent DE-3042423-A1 (DE)
Inventor: BRECKEL WERNER DIPL ING
IPC: F02P17/06
Filed: 1980-11-11
Abstract: A flash unit is proposed which ensures the operational readiness of thyristor-triggered flash units even when a plurality of triggering pulses are emitted shortly after one another. If a further triggering pulse follows shortly after the flash has been triggered, the triggering capacitor (12) is not yet in a charged state so that a further flash can be triggered. Although the thyristor (3) triggers, the triggering capacitor (12) continues to conduct via the bias resistor (9, 10) as a result of the quiescent current, that is to say it can no longer turn off. The thyristor (3) is turned off in such situations by means of a switch (6) which is connected in parallel with the thyristor (3) and is briefly closed during each triggering pulse. <IMAGE>

IPC: G01R31/34
Filed: 1980-12-01
Abstract: The testing arrangement for short circuit rotors (1) enables all possible defects to be detected and identified as to type and position, including those not affecting the magnetic field strength such as inadequate material in the cage. The voltage drop on the cage is measured by using the static contact points (13) placed separately from the short circuit rings (2). A voltage dependent measurement indicator (12) is connected to the contact points. The indicator arrangement consists of a two channel recorder with one channel connected to the contact points and the other channel attached via the measurement probe (9). The separate contact points lie on a plane through the rotor longitudinal axis (5) making a defined angle with the plane contg. the other contact points (6).
