Title: Drehzahlregelvorrichtung für einen Motor
IPC: H02P29/00
Filed: 1984-11-22
Granted: 1986-10-02
Abstract: Bei einer Drehzahlregelvorrichtung für einen Motor zum Antreiben eines Aufzeichnungsträgers, auf dem ein Informationssignal und ein Synchronisiersignal aufgezeichnet sind, wird die Klemmenspannung (Vc) eines Kondensators (C1) einer Filterschaltung (20) dem Motor als ein erstes Regelabweichungssignal (V1) zugeführt, wenn der Motor (11) mit einer Stationärzustandsdrehzahl läuft. Das erste Regelabweichungssignal entspricht der Differenz zwischen dem wiedergegebenen Synchronisiersignal und einem ersten Bezugssignal. Wenn die Motordrehzahl von der Stationärzustandsdrehzahl abweicht, wird die Kondensator-Klemmenspannung in Abhängigkeit von der Amplitude eines zweiten Regelabweichungssignals (V2) gesteuert, das der Differenz zwischen einem zweiten Bezugssignal und einem Drehzahlistwertsignal entspricht. Die beiden Regelabweichungssignale sind dem Motor wählbar zuführbar und auf weitgehend den gleichen Wert einstellbar, wenn das dem Motor jeweils als Drehzahlsteuersignal zugeführte Regelabweichungssignal von dem zweiten auf das erste Regelabweichungssignal umgeschaltet wird. Dabei ist der Regelvorgang weitgehend unabhängig von Störungen stabil, selbst beim Umschalten der Regelabweichungssignale.

Granted: 1999-03-18
Abstract: The device has at least two co-axial centrifugal masses, operating against the action of a damping device. The two masses can turn relative to each other via a roll bearing.  The two masses both act against an axial springing device between them depending on the operation of a friction clutch, and are capable of limited axial movement relative to each other. The axial springing device may act on the second mass opposing the disengaging force of the friction clutch.

IPC: E21D9/04

Granted: 1989-09-07
Abstract: A steel pipeline to be driven through an earth section without disturbing the overlying earth is made up of a plurality of serially arranged axially extending pipe sections each having a leading end and a trailing end. The leading end of each pipe section abuts the trailing end of the pipe section previously driven into the earth section. A pressure-tight pipe connection between the abutting ends of the pipe sections is formed by a steel ring secured within the trailing end of the pipe section and projecting axially out of the trailing end. The steel ring has an outside diameter smaller than the inside diameter of the section. The leading end of the next pipe section has an elastic material sealing ring secured to its inside surface with the sealing ring projecting radially inwardly beyond the outside surface of the steel ring. The steel ring contacts the sealing ring and deforms it into a pressure-tight seal when the leading end of the next pipe section abuts tightly against the trailing end of the previously driven pipe section. The pipe connection permits angular deviation between the axes of the pipe sections with stops located in the pipe section affording a shear force lock between the abutting pipe sections.

Abstract: An adjusting device for an electrode in a metal smelter. The device has a pressure mechanism comprising a, preferably, one-piece, ring-shaped flexible tube filled with a pressure medium. The pressure mechanism is positioned between clamp elements and radially positioned around the electrode and a frame. To ensure the secure retention of the electrode and increase the service life of the material of the pressurization tube, through a simple structural means, the present invention provides that the clamp elements have retaining brackets and guide brackets that are positioned to slide horizontally on the frame and support elements that are partially in contact with the tube that is filled with the pressure medium. The support elements are provided on the clamp elements.

Abstract: A personal computer has two memory banks (12,14) respectively connected to two parity check units (16,18) operative to detect parity errors. Upon doing so, each unit (16,18) feeds a parity error signal to a separate latch (22,24). The latches (22,24) are connected to a logic circuit (26) which is in turn connected to an interrupt controller (34) that initiates an interrupt (36) when a parity error occurs. One latch (22) is further connected to a check bit (41) of a register (40) of an I/O port (38) and the check bit (41) is set by the one latch (22). An interrupt handler reads the register and provides messages indicating which memory bank (12,14) caused the parity error.

Abstract: 2.1 In securing data traffic in known systems of this type, discrepancies occur between optimum protection against unauthorised intervention, even of an internal nature, on the one hand and hindrances to use, e.g. storage problems and the protection of personal data, on the other hand. 2.2 In the method according to the invention, a mutually exclusive division of the scopes of authorisation is carried out, in which one type a) relates to the operating system and to the guaranteeing of availability and reliability, and a second type b) serves to prevent and identify unauthorised intervention and to collect associated operator data. For this purpose, two separate databases with different methods of access are formed and a session number is set up as an aid to data integration. 2.3 The invention is suitable for all types of security management systems in distributed and complex data transmission, telecommunications and data processing systems, even for commercial payment transactions.

Abstract: By the invention it is intended to bring about a rapid build-up of the mould pressure for the compressed-air forming of an article made out of a thermoplastic sheet, without exceeding the predetermined value. This is achieved by installing a proportional valve, which feeds the forming air initially with the full cross-section and then, dependent on the forming pressure produced, constricts this cross-section shortly before reaching the forming pressure and closes it when the forming pressure is reached. The invention is represented characteristically by Figure 1. <IMAGE>
