Patent DE-19602920-A1 (DE)
Inventor: GROS-WEEGE JOHANNES DR ING
IPC: B21D3/12
Filed: 1996-01-22
Abstract: The invention concerns a process for producing pipes, particularly large pipes using the UOE-process, in which the pipes are calibrated stepwise up to half a pipe length using cold expansion after inside and outside welding. At the same time, cold expansion is also used for dressing. The pipe is thereby clamped at the least possible distance from the expander head and the free end of the pipe is flexibly deformed and subsequently the pipe is cold-expanded in the known fashion. The pretension force decreases on its own and, after release of the clamping and the remaining pre-tension, a step-wise shifting of the pipe by the amount of the expander-increment up to half the pipe length occurs, and the process is repeated for the other half of the pipe. In addition, the invention concerns a device for carrying out the process.

Patent DE-19619058-A1 (DE)
Inventor: HAUGRUND JUERGEN DIPL ING
IPC: G06F15/02
Filed: 1996-05-02
Abstract: Calculating aid for calculations with simplified operand input via one or several control elements. In prior art calculation aids, e.g. digital calculators, operands are fed in via a numeric keyboard. Single-handed operation is therefore almost impossible or very difficult if there is not suitable support available. The novel calculating aid is designed for single-handed operation, with the aid operated and held by one and the same hand, leaving the other hand free for other operations. The operands are fed by position. The basic symbol needed for the position to be inputted is selected by repeated operation of the same control element from the basic set of symbols. The calculating unit makes it possible to perform any calculating operations. For example, several sums of money may be inputted successively via three control elements and displayed as a sum.

Title: Control system especially for forced draught gas fired burner
Inventor: NOLTE HUBERT
IPC: F23N5/12
Filed: 1996-08-16
Abstract: The control system includes an ionisation electrode (6) which is located in the flames of the burner. A microprocessor controller (15) is coupled to the electrode. The electrode is supplied by an AC current which is superimposed by an DC current corresponding to the ionisation current. The combined potentials form the input to a comparator (10) in which the DC offset potential determines the duration of the fixed amplitude comparator output voltage as a result of point-on-wave cut-off.  The duration is independent of the AC amplitude and the resultant digital signal is opto-coupled (13) to the microprocessor controller with a D/A converter (16). The fuel inlet valve (3) and the fan speed control (5) is regulated.

Title: Electronic goods monitor detecting presence of indicator
Inventor: KLAEHN DAVID P
IPC: G08B13/24
Filed: 1996-08-23
Abstract: To detect the presence of a marker 60, an electronic article-surveillance apparatus includes a transmitting circuit 10 and a transmit antenna, 12 and a receiving antenna 16 next to the transmit antenna 12. An electromagnetic signal is generated within a controlled area, the signal being received by the receiving antenna 16. When the marker 60 is in the controlled area, a disturbance is created in said electromagnetic signal and is picked up by the receiving antenna 16. The disturbance is the marker signal. An electronics module 18 receives the electromagnetic signal picked up by the receiving antenna, and a feedback conduit, linking the electronics module 18 with the transmitting circuit 10, controls the amplitude of the electromagnetic signal so as to maintain the marker signal at a constant amplitude and shape. A detection module 20 analyzes the marker signal. An alarm circuit 22 is actuated by the detection module when the latter confirms the presence of the marker signal having predetermined features.

Abstract: In order to improve the sealing properties of two interconnected drive pipes (101, 102) and to achieve positive-fit locking, the invention provides two compatible, esentially L-shaped receiving recesses (115, 119, 122, 129) located one behind the other in a socket end and on a spigot end (111, 120).  A receiving recess (122) on the spigot end has a receiving surface (123) in which there is a seal-accomodating groove (130) with a built-in sealing ring (131). Located between the first and second socket end recesses (115, 119) is at least one, at least partially encompassing sliding block (114). Its beveled gliding plane (116) is used for driving on to the anchor block (124) of the spigot end. When the spigot end is pushed into the socket end, the sliding block (114) slides onto the anchor block (124) and comes to rest on the bevel (126.1) of the sliding surface (126) which is sloped at around 45 DEG  in the bottom area of its rounded-off sliding face (114). The seal pressing area (113) is raised up so far that it slides over a sealing ring (131) placed in the seal accomodating groove (130) without pushing it out of the groove or damaging it. When pushed in further, the sliding block (114) slides over the sliding plane (126.2) and engages in the sliding recess (128) located behind the anchor block (124) in the receiving end.
