Title: Electrohydraulic switching device
Inventor: STEFFES HELMUT
IPC: H01H35/26
Filed: 1986-05-16
Abstract: An electrohydraulic switching device is proposed for emitting electrical control signals as a function of pressure signals which are supplied, with a housing in which a piston (which can be acted on by the input pressure) is arranged such that it can be displaced axially, which piston is loaded against the input pressure by means of a compression spring which is supported on a spring plate which is connected in a positively-locking manner to the piston, and a switch is provided which is arranged coaxially with respect to the piston and switches over suddenly, which has at least one contact pair, a switch housing, a snap-action switching mechanism and an operating element which causes the sudden switching-over of the switch as a result of the change in its geometrical position with respect to the switch housing. In order to specify a switch device which is structurally simple, can be produced cost-effectively, can be adjusted easily and operates reliably, the invention provides that the snap-action switching mechanism is formed by an operating plate 22, which is prestressed in the axial direction, and a lock 18, which holds the operating plate 22 in position, can be operated by the operating element 9 and interacts with a fixed-position part 21 on the switch housing 20. <IMAGE>

Title: Gasket sheet of a flat gasket and process for the production thereof
Inventor: ANHORN THOMAS DIPL ING
IPC: C09K3/10
Filed: 1987-02-25
Abstract: Process for the production of gasket sheets for flat gaskets, in particular cylinder head gaskets, whose soft material contains fibres, fillers and, as binder, nitrile rubber and, to improve the water resistance, is to be treated with a silicone compound. To make possible their curing, the nitrile rubber is vulcanised with a sulphur-free vulcanisation aid, namely a quinone dioxime, which in view of the high proportion of fibres and fillers in the soft material and thus the low proportion of binder, surprisingly is also effective as a vulcanisation aid in the case of nitrile rubber.

Title: Apparatus for the plasma arc cutting and welding of metal workpieces
Inventor: DINSE WILHELM
IPC: B23K9/10
Filed: 1987-05-06
Abstract: The apparatus for the plasma arc cutting or welding of metal workpieces is equipped with an electrode and a nozzle body in a corresponding housing and having the plasma nozzle bore. There is provided a safety cut-out which ensures the circuit is broken whenever parts subject to wear, in particular the electrode 14, are to be replaced. This safety cut-out 6 to 8 is located at that end of the housing 5 which is remote from the nozzle body 15, so that it is not exposed to excessive thermal stress. The safety cut-out breaks the circuit immediately by detaching the nozzle body 15, so that the circuit is also actually broken when the electrode can be touched. Touching the nozzle body 15 does not constitute a safety risk because the nozzle body has the sale polarity as the workpiece. <IMAGE>
Patent DE-3715491-A1 (DE)
Inventor: GLEIM GUENTER
IPC: G11B7/09
Filed: 1987-05-09
Abstract: An arrangement for reproducing data readable by an optical scanner from tracks on a recorded medium. At least one beam of light is focused onto the medium, and the beam is positioned along the tracks by a tracking control. The recorded medium reflects the beam onto a photodetector which generates an electrical data signal having a phase relation, a focusing error signal also having a phase relation for indicating the current state of the focus control. A tracking error signal also supplied by the photodetector indicates the current state of the tracking control. A control amplifier is connected in the focus control and has an offset voltage. An offset compensation voltage is supplied to the input of the control amplifier for compensating the offset voltage of that amplifier. The offset compensation voltage is varied at the input of the control amplifier until the phase relation of the focusing error signal coincides with the phase relation of the data signal for obtaining the correct value for the offset compensation voltage.

Title: Method and arrangement for capturing fault events divided into fault categories
Inventor: NUSSBAECHER HANS-KLAUS
IPC: G06F11/07
Filed: 1987-09-30
Abstract: In data processing systems, to capture fault events which are divided into at least two fault categories according to urgency, a fault signal (FA) is derived from the fault event signals (FE) which are present at one interrogation time, and fed to a fault signal memory (FSn) for each fault category. The output signals of the fault signal memories (FA1 to FAn or FA1-N to FAn-N) control a locking device (VE), so that if a fault is indicated, the acceptance of subsequent fault event signals is suspended. Also, before each acceptance of fault event signals (FE), fault category signals (FKn) which indicate the fault category are fed to the locking device (VE), which, depending on these signals, removes the suspension which is in effect. Thus the highest-priority fault event signals, which determine how faults are handled, are stored inside a basic circuit arrangement. <IMAGE>

Patent DE-3801994-A1 (DE)
Inventor: FISCHER ARTUR PROF DR
IPC: A61C13/225
Filed: 1988-01-23
Abstract: Metallic precision attachments/telescopic crowns are usually used as a releasable connection for a combined fixed/removable denture. Metal-based precision attachments must generally be soldered, welded or cast on. The incorporation of the precision attachments necessitates a considerable expenditure in terms of material and time. In the case of a loss of friction, metallic precision attachments/telescopic crowns can only be repaired (if at all) at considerable financial expense. 
<??>In order to provide a denture attachment which is cost-effective and can be used in many ways, spark erosion is used to introduce a groove profile between the telescopic crown and the attached crown of the denture part, into which groove a profile rod made of polyamide is inserted as an elastic friction element. The friction element thus formes a frictionally engaged attachment between the telescopic crown and the crown arranged on this.
