Patent EP-0378287-A1 (EP)
Inventor: SCHLAWNE FRIEDHELM DR RER NAT
IPC: G01N29/04
Filed: 1990-01-08
Abstract: The invention relates to a method for detecting flaws in oblong workpieces, in particular in pipes and rods, by means of ultrasound. 
<??>The test piece (2) is fed past at least one stationary electrodynamic transducer (1) in its axial direction without turning and tangentially circulating wave pulses (A, B) are produced in the test piece which propagate in both circumferential directions. These are so chosen that they destructively interfere at the site (3, 4) of the receiver. In a perfect test piece (2) no signal is consequently produced at the receiver. According to the invention, the incoming signal and a burst signal whose chosen cycle time is less than a quarter of the circulation time of the wave pulses round the test piece and whose decay time length is equal to the undisturbed wave pulses in a perfect workpiece is applied for every cycle to a peak detector; the output signal is digitised and transferred to a computer.

Abstract: Apparatus for locking a packer against premature actuation in a well bore comprises a sleeve (44,70) attached to a lower end of the packer and spring biased locking members (88) adjacent to the sleeve. When in a locked position, lugs (90) on the locking members (88) engage a groove (82) in the sleeve and prevent longitudinal movement of a mandrel (62) in the packer with respect to the packer elements. When the locking apparatus enters a liner in the well bore, the locking members (88) are biased radially inwardly, disengaging the lugs (90) from the groove (82), so that the packer mandrel may be actuated and the packer set.

Title: Telecommunications system.

IPC: H04W72/08
Filed: 1990-01-26
Abstract: A communication procedure suitable for a cordless telephone system involves time division duplex radio communication between a handset 11 and a base station 3 using alternating bursts of transmission over a single radio channel. Once a radio link has been set up, initial transmissions carry a synchronisation logical channel S and a signalling logical channel D multiplexed together, but the link may switch to bursts carrying a communications logical channel B for the speech data and the signalling logical channel D. Burst synchronisation is achieved by the asynchronous detection of words in a synchronisation channel S. These words have bit patterns reducing the probability of incorrect asynchronous detection of them.   If one part ceases to receive handset signals from the other, it transmits a special signal, informing the other part. This enables both parts to detect the failure of a link at substantially the same time, so that their actions to re-establish the link are synchronised.

Title: Procedure and machinery for the production of an assembled object.
Inventor: GRAM JES TOUGAARD
IPC: B29L1/00
Filed: 1990-07-11
Abstract: The invention concerns a procedure for the manufacture of an assembled object intended for repeated assembling and disassembling, e.g. a tube (1) with matching cap (4), and a machine for the execution of this procedure. According to the invention the tube (1) and the cap (4) are cast in the same mould (7) and ejected simultaneously and assembled in the exact position they are to have when used. This can suitably be done by first casting the part (4), which at the boundary surface is placed outermost. When it has assumed its final shape, it serves as an independent mould when producing the other part (1). The first cast part (4) thus contribuates to the securing of the core system (9, 10, 11) for the other part (1), whereby the wall thickness of this part can be made especially uniform and thin. The machine for the execution of the procedure can thus cast e.g. the assembled cap (4) and tube (1), and it can, therefore, also be adapted to perform an automatic filling, sealing and possibly stamping of the tube.

Le fluide hydraulique réagit au mouvement de l'élément hydraulique en se déplaçant de l'élément hydraulique à un dispositif récepteur, lequel accomplit une opération causée par le mouvement du fluide hydraulique. Lorsqu'on refroidit le matériau à mémoire de forme afin de le ramener de l'état austénitique à l'état martensitique, l'élément hydraulique reprend sa position originale, un élément de sollicitation étant prévu pour ramener l'élément hydraulique vers sa position de repos.

Abstract: 2.1 The invention relates to a control valve for controlling a high pressure line, preferably an injection line for diesel internal combustion engines. A disadvantage of these control valves is that the flow, when being reduced, breaks down behind the control valve seat, tending to cavitation.
