Title: Mfr. of screen printing stencils - by film laminating a textile, galvanically depositing a print pattern, and removing the film
Inventor: KOCH DIRK ING GRAD
IPC: B41C1/14
Filed: 1975-07-17
Abstract: Method comprises covering 1 side of a textile with a foil; forming, on the uncovered side of the textile, a desired printing design by galvano-deposition of a metal and removing the foil. Specifically, as thermoplastics foil is used. Before the galvanic deposition of the metal, both the textile and that side of the foil facing the textile are coated with a thin galvanisable, metallising layer. The printing design is built up from non-porous metal that is firmly anchored to the textile.

Title: Stabilised steering linkage for front wheels - with asymmetric displacement of wheel pivots using angled levers
Inventor: RUF GEBHARD DIPL ING
IPC: B62D17/00
Filed: 1975-08-09
Abstract: The track rods(28) of the front wheel steering linkage are connected to angled levers (27, 27a) which are joined by a cross strut and which are connected to the bearing support arms(1) by control rods (29). As the wheels are turned for steering the angled levers move the wheel bearing levers asymmetrically. The outside wheel, on cornering, moves rearwards while the inside wheel moves forwards. This provides a stabilised steering, whish uses fewer levers than conventional layouts, and in which the amount of steering compensation is adjustable by a movable link.

Title: Analogue signals transmission system - uses increment generator for generation of pulses proportional to analogue signal
Inventor: STEFFENS KLAUS
IPC: H04Q9/14
Filed: 1975-12-22
Abstract: The pulses change the state of a counter. A control line transmits from an operating point the counter content as control signal, together with an address to a selectable unit. A signalling line transmits from the selected unit a message giving its operational state, together with an address. Before the state of the counter (4) is changed by pulses of the increment generator (3), the existing state of the unit is written into the counter (4) through the signalling line (1).

Title: Cutter for natural and artificial stone blocks - uses high pressure water jet with fine nozzle of hard material
Inventor: GRESSER JUN GERMAN
IPC: B26F3/00
Filed: 1976-02-19
Abstract: The cutter is for cutting and trimming natural and artificial stone blocks and comprises one or more high-pressure pumps for forcing water through a pipe into a cutting head with max. pressure which can be varied according to requirements by a pressure regulator.

Title: Collet for resisting shaft axial movement - has low friction locking ring gripping end of split sleeve
Inventor: STOLBERG FRITZ R
IPC: F16B2/14
Filed: 1976-05-31
Abstract: A clamp for resisting the axial movement of a shaft consists of a split collet (1) and a locking ring. The split collet has a collar at one end and four spring fingers formed by longitudinal slots. The outer surface of the ends of the spring fingers is of conical form and covered with a material having a low coefficient of friction. A locking ring with a tapered bore fits over the spring fingers and clamps them against the shaft. The coefficient of friction between the collect and shaft is relatively high so that a large clamping force is achieved for a relatively low force exerted on the locking ring.

Title: Data read=out facility for energy consumption meters - has internally stored data displayed via LEDs and optically interrogated
Inventor: SEIBT ARTUR DR ING
IPC: G01R11/00
Filed: 1976-08-03
Abstract: The data read-out facility for computer storage of energy consumption meters is based on an optical display comprising l.e.d.s etc. which represent the data stored in the meter. An internal microcomputer is used as a store. An optical reader head provides a start command signal which causes the stored data to be transferred from the meter register to its display window. If the display has only one optical device, the data is read out in 1-bit serial form. The meter is fitted with a number of photo-detectors and light-guides connected to its store so that it may be programmed from outside by optical means. In this way, different types of data may be read out when it is next interrogated by the reader head.

Abstract: Dry solid polyacrylamide is produced by depositing an aq. soln. of acrylamide (I) and an aq. soln. of polymerisation catalyst (II) onto a heated moving surface so that the acrylamide exothermically polymerises and all of the water evaporates. The acrylamide soln. comprises 60-80wt. % (I) and 20-40wt. % water and is first heated to 50-100 degrees C. The moving surface is heated to between 50 degrees C and the charring pt. of (I). The catalyst (II) is pref. an alkali metal or ammonium sulphite, bisulphite or persulphate, used as pref. 0.1-5 wt. % (on wt. of (I)). Pref. (II) is sodium bisulphite or ammonium persulphate. Dry solid polyacrylamide is used e.g., in conjunction with bentonite to prevent seepage of water in earth filled dams and together with expanding lattice clays (e.g., bentonite) in drilling muds. Process is efficient and no monomer is lost or wasted. The prod. is ready for use without further processing except for grinding to the desired particle size.

Title: Riser removal from cast roller - has rolling mill casting supported on cradles for parting riser and drilling centres
Inventor: THOMA HANS DIPL ING
IPC: B21B28/02
Filed: 1977-07-16
Abstract: The raw casting for the roller of a steel rolling mill is cast with a riser at one end which has to be removed before the centre can be drilled for subsequent machining. This is simplified by first supporting the casting (6) on two cradles (1, 2) which run on rails (3). A parting tool (12) mounted on a bogy (11) cuts off the riser (10). The centres are then drilled in each end by the travelling drills (17, 18) after which the casting is removed and transferred to a lathe for turning the outside dia. This method of removing the riser (10) eliminates the need for making a centre hole in the riser before it is removed by machining.

Title: Failsafe AC voltage supply for loads - has constant voltage transformer and control unit which couples failsafe bus=bar to standby current source via switching device
Inventor: MUENCHOW EBERHARD ING GRAD
IPC: H02J9/06
Filed: 1977-08-02
Abstract: A fail-safe busbar is connected through a first switch and an a.c. controller with a transformer to a.c. mains, and through a second switch to a standby supply unit. A control device monitoring the mains voltage so controls the switches and the standby supply unit that the busbar is connected to the mains when its voltage is within the specified tolerances. If the voltage is outside the tolerance limits, the busbar is connected to the standby unit ready to deliver power. The a.c. voltage controller stabilising transformer is motor driven. The control device connects the busbar through the second switch to the standby supply unit, when the rate of change of the mains voltage exceed the speed of the variable transformer control.

Title: Linearly adjustable transistor amplifier - has mirror circuit forming with transistor comparator extending voltage drop
Inventor: REHFELDT KARL-HEINZ DIPL ING
IPC: H03G1/00
Filed: 1978-03-31
Abstract: The amplifier has a reference point at the collector resistor connected to the supply source positive terminal and controlled by a first transistor in accordance with collector current of a second transistor controlled in the opposite sense. The voltage drop across an impedance in the second transistor collector circuit is transmitted to the reference point by a third emitter follower. The base-emitter voltage of the latter is balanced by a further transistor. The voltage drop across the impedance (19) is applied to a fourth transistor (4) which forms with a current mirror circuit (26-28) a comparator which transmits to the third transistor (3) the base voltage of the fourth transistor (4).
