Title: Container aluminium sheet joining system - has sheet edges bent to form halves of U=section held by U=section outer member and bar
Inventor: LANG HORST
IPC: B65D6/30
Filed: 1979-07-07
Abstract: The arrangement is intended for producing a container, whose wall and bottom panels consist of flat elements, such as aluminium sheets. The sheets can be shaped by plastic deformation and are joined together or to a sectional member along their edges. The edges are bent over and shaped at least once so that together they form a U-section and are joined by fitting them into a correspondingly shaped U-section connector which is then secured by inserting a locking bar in the U-section slot formed by the edges, thus producing a firm dovetail joint. The sides of the U-sections preferably converge upwardly to include an angle of 60 deg.

Title: Winding machine for paper tape, etc. - has intermediate buffer store of tape between supply roll and winding head
Inventor: BURGHOFF FRIEDHELM
IPC: B65B41/12
Filed: 1980-05-24
Abstract: A winding machine for producing rolls of, e.g. paper or jute tapes has a buffer store between the supply roll and the winding head in which tape drawn from the supply roll is deposited in horizontal layers by a pair of feed rollers mounted on a traversing carriage. The tape passes downwards through the storage box at constant speed, and is drawn off from the bottom by the winding head. This arrangement enables the speed of the supply roll to be limited without affecting the winding speed, enabling the supply roll to be rapidly braked when necessary. It permits the replacement of the supply roll without necessitating interruption of the winding process.

Patent DE-3044835-A1 (DE)
Inventor: BRAUN REINHOLD DIPL PHYS
IPC: H03D13/00
Filed: 1980-11-28
Abstract: In a phase monitoring circuit, which for a phase-locked-loop regulating system uses only one digital phase detector, to which a reference signal and a comparison signal are fed, and in which an output signal corresponding to the phase difference is output to control a voltage-controlled oscillator, there is the danger that, after a failure or an interruption of the reference signal, the phase detector, in certain cases, does not set the phase difference after restart to zero, but to 2 pi . To avoid this, a correction circuit (KS) is connected in series before the phase detector and delays connecting the signals through to the phase detector after the reference signal restarts in such a way that the falling edge of the reference signal is fed to the phase detector simultaneously with or delayed after the falling edge of the comparison signal. The correction circuit (KS) includes a retriggerable monostable flip flop circuit (MF) to monitor the reference signal (R), a gate circuit (G3) with inputs for the output signal (Q) of the monostable flipflop circuit (MF) and the comparison signal (V), a multivibrator consisting of two gates (G4, G5), an inverter (G6) and two through-connecting gates (G1, G2). One input of one of the through-connecting gates (G1) is connected to a capacitor (C1). <IMAGE>

IPC: B29D30/64
Filed: 1981-01-31
Abstract: The invention relates to a process and an apparatus for testing pneumatic vehicle tyres. The testing apparatus includes a tyre-turning device and a spreading device. For the testing apparatus, it is proposed that it has a clamping device with clamping elements for fixing a tyre bead, that spreading elements of the spreading device are arranged movably in such a way that, during the cross-sectional spreading of a tyre being tested, they act on the side wall or shoulder of the said tyre adjacent to the clamped tyre bead, clamping elements serving as abutments, and that no elements of the testing apparatus act on the side of the tyre under test opposite the clamped tyre bead. With the apparatus, the simultaneous spreading of a tyre over the entire circumference accomplishes a significant increase in the field of view of the inside of the tyre, in particular in the circumferential direction.
