Patent DE-2811417-A1 (DE)
Title: Mounting metal strip feeder on presses, shears etc. - via bracket which can be adjusted vertically by motor driven spindle and then clamped
Inventor: FREI HANS-JOACHIM
IPC: B21D43/11
Filed: 1978-03-16
Abstract: The feeder drives the metal sheet or strip into a press, stamper, shears or other metal working machine. The machine is fitted on its inlet with a stationary assembly plate, each side of which has a bearing plate for supporting a shaft carrying one or more eccentric discs. The vertical leg of the mounting bracket is located between the assembly plate and shaft. A lever is fixed on the shaft and is actuated by a work cylinder, pref. a hydraulic cylinder, to rotate the shaft and thus clamp the mounting bracket. Prior to clamping the bracket, a motor pref. uses a pair of bevel gears to rotate a spindle adjusting the height of the mounting bracket. This makes it very simple to clamp and adjust the height of the mounting bracket, thus adjusting the height of, and clamping, the feeder.

Title: Belt drive for motor vehicle engine auxiliary equipment - has clutch to change drive ratio according to engine speed
Inventor: WOESSNER GUENTER DIPL ING DR
IPC: F02B67/04
Filed: 1978-03-23
Abstract: The crankshaft (14) of the engine (13) has a pulley (15) from which a belt drives a pulley (16) on the shaft of the servo system pump (11). Two pulleys (18, 19) are supported on bearings on the pump shaft so that they can turn independently of it. Each of these pulleys is connected by a belt to a pulley (21) on the shaft of a generator (12) or other auxiliary equipment. A hydraulically operated clutch (22) can put one or other of the auxiliary equipment pulleys (18, 19) into direct contact with the pump pulley (16). The clutch is operated to change the auxiliary equipment drive at a preset engine speed.

Title: Data terminal for handling texts - with separate buffer and bulk stores providing autonomous operation
Inventor: BRENDES HORST DR ING
IPC: G06F13/12
Filed: 1978-03-30
Abstract: The data terminal consists of a keyboard (4), a printer (5), store (6) and control unit (7). Texts prepared on the keyboard are printed out and at the same time encoded and stored in the operating store. After correction and modification the data is passed via an interface (2) to a buffer and bulk store arrangement (10). The text can then be transmitted over a communication line (13) via the sending unit. A control unit (9) comprising a CPU and program store supervises the operation. Incoming data is passed via the transmitting unit to the bulk store. A command from the terminal keyboard allows the data to be passed via the two-way interface to the terminal's store (6). The data may then be printed out as required. Depending on the amount of data passing from the terminal to the line, this data is first passed to the bulk store if the capacity of the buffer (14) is exceeded.

Title: Avoidance of over heating in induction furnaces - after reduction in throughput, full load not being re-established for 10-15 per cent of the furnace length
Inventor: MAUVE HANS WERNER
IPC: H05B6/06
Filed: 1978-07-20
Abstract: Overheating in forging billets in induction furnaces is avoided when the furnace throughout is halted or reduced. The billets are pushed through the furnace end to end. At low load, the furnace is controlled to hold the billets at the soak temp. When the load is returned to normal, the pusher speed is increased first. The induction load increase is delayed for a certain period. If the speed increase is say from 25% to 100%, the increase to 100% induction load would be delayed for 10-20% of the inductor length esp. 15%. For use on pusher type forging billet heating furnaces. Avoids overheating after a load reduction with temp. hold condition.

Title: Coupling aid for drawbar - is constructed with coupling hook on double hinged support with snap fastening catches to tractor
Inventor: PLANK JOHANN
IPC: B60D1/58
Filed: 1978-08-16
Abstract: The coupling aid for the tractor has the towing hook mounted on a bar which is itself linked to a second bar by a vertical pivot and with the second bar similarly pivotted on the rear of the tractor with its other end. The whole system folds flat against the rear of the tractor where it is secured by strong catches. The system is extended to couple to a trailer and the tractor backed towards the trailer to cause the aid to fold flat. No manual effort is required for a rapid and accurate towing connection. The bars assume angles less than 90 deg. to each other so that strain on the pivots is minimised.

Title: Monolithic integrated circuit for radio receiver - has tunable ring oscillator comprising integrated injection logic and clocking bucket brigade device
Inventor: ABLASSMEIER ULRICH DR
IPC: H03J3/16
Filed: 1978-12-07
Abstract: The integrated circuit has a bucket brigade circuit and a clock generator. The latter consists of an integrated-injection-logic ring oscillator tuned via the injection current of one stage and producing the clock signals for the bucket brigade circuit forming a resonant circuit in the receiver. The bucket brigade circuit is therefore also tunable. A current amplifier and a level transformer are located between the output of the ring oscillator and the clock input of the bucket brigade circuit. Two exclusive-OR gates driven by the level transformer produce two mutually inverted clock pulse sequences for clocking the bucket brigade circuit. The circuit can be used in receivers other than for radio.

Title: Identification of bar code markings - has bar code information located in tolerance bands to avoid sensitivity to distance and scanning velocity
Inventor: KUGLER ROLAND ING GRAD
IPC: G06K7/10
Filed: 1979-03-19
Abstract: An identification system for bar code marking on article labels is designed to provide insensitivity to variations in the distance of the scanning probe from the label and variations in scanning velocity. The bar code markings begin with two markings (1, 2) that define the start of the information block, followed by a blank tolerance field (5). A marker bar (4) indicates that the following segment (5) contains information (6) which may be a '1' or '0'. Following information is prefaced by a marker. All markers (1, 2, 4) are in the form of full lines, whereas an information '1' level is represented by an outline field. Any information mark within the tolerance band (8) is acceptable. An associated digital identification stage processes the generated signals.
Patent DE-2913876-A1 (DE)
Inventor: BALL HUGO DR RER NAT
IPC: B29D23/00
Filed: 1979-04-06
Abstract: The pipe for the transport of warm or hot fluids comprises an inner tubing (1) forming the transport pipe, an external protective tubing (4) and a heat insulating layer (3) disposed in between. The internal tubing (1) is made of a synthetic material armed with glass fibers and is surrounded by a metallic sheet (2) acting as a vapor screen since the synthetic material is vapor-permeable. In order to avoid the formation of water pockets, the metallic sheet (2) is applied onto the inner tubing (1) without forming air pockets. When the inner tubing is formed of epoxyde resin, a rotational moulding is particularly appropriate whereby the wall of the mould is lined with the metallic sheet (2) for obtaining the inner tube of a part, the metallic sheet forming a construction unit. If the inner tubing (1) is made of a vinylic polyester the metallic sheet may be wound helically around the inner tubing by applying a tension or by pressing it against the tubing in order to prevent the formation of air pockets. To link neighbouring tubes a sleeve (6) of synthetic material is glued onto the naked end of the inner tubing (1) which is also provided with a metallic sheet (2) and comprises a wedge-shaped zone (10) into which the naked end of the neighbouring tubing is inserted and secured by means of a synthetic glue (11). Because the vapor diffusion takes place nearly only in a radial direction, the axial slot between the metallic sheets (2, 2a) does not have any negative influence on the vapor screen in the joining zone, especially if the metallic sheet comprises an axial overlap.

Abstract: The production of wound foil capacitors is facilitated by a high performance winding process. The process utilises a drum onto which is wound metalised dielectric foils that are separated by isolating foils. When the diameter has been built up to the required diameter, the complete stack is subjected to a stabilising process. Following this the stack is sliced into separate single capacitors. Final wrapping of each individual capacitor element completes the process.
