Title: Method for measuring balanced voltage components in a multi-phase system, and devices for carrying out the method
Inventor: SIDLOVSKY ANATOLIJ KORNEEVIC
IPC: G01R29/16
Filed: 1982-07-28
Abstract: The invention relates to metrology. The method consists in generating the reference signals which, according to the invention, represent a system of two orthogonal sinusoidal signals, multiplying of their instantaneous values by the instantaneous values of the phase voltages and averaging the products obtained. After the averaging, the average values of the products are added to the corresponding weight factors for separating orthogonal components of symmetrical sequences, in accordance with which the parameters of the balanced components are evaluated. Devices for carrying out the method according to the invention are also proposed which are built up on the basis of digital computer technology. In the preferred variant of the embodiment, the device according to the invention contains a change-over switch (25), a voltage-code converter (27) and a computing unit (29), which are connected in series and are synchronised in their function by a control section (28). A frequency multiplier (26), which is also connected to one of the phases of the multi-phase system to be examined, is connected to the input of the control section (28). In this modification, the output signal of the computing unit (29) carries the information on the parameters of the balanced components of the said multi-phase system. The present invention is particularly well suited for use in measuring and information systems for measuring the quality characteristics of the electrical energy of a three-phase system. <IMAGE>

Title: Screwing tool
Inventor: RISSMANN HORST-GUENTER
IPC: B25B23/14
Filed: 1982-07-30
Abstract: In a screwing tool having a drive member and a work member, which are arranged coaxially in housing and interconnected by means of a disengageable coupling which is loaded by means of a spring in order to limit the transmissible torque, the coupling is effected by means of two mutually coaxial rings of equal-sized balls, which, when the coupling is engaged, overlap in the region of the gores and thus effect a locking in the circumferential direction. On exceeding the preset torque, the balls disengage, with point contact and compression of the spring. The use of commercially available balls entails a substantial lowering of the manufacturing costs owing to the reduced processing need. <IMAGE>

Patent DE-3246399-A1 (DE)
Title: Control flap
Inventor: SCHENK EGON
IPC: F16K1/24
Filed: 1982-12-15
Abstract: The control flap has an eccentrically supported flap disc which is pivoted in the opening direction as far as the respective control position by the medium pressure and is loaded in the pivoting direction for closure by a closing weight. According to the invention, the closing weight is a guide cup which at each of its two ends carries at least three running rollers distributed over the circumference, projecting from the circumferential surface of the cup and having a cambered running surface and which can be moved axially in a loading cylinder placed perpendicularly onto the flap housing. The additional weights necessary for the particular control are accommodated in the interior of the guide cup. The opening forces acting on the flap disc are transmitted to the guide cup via a toggle lever which is connected, on the one hand, rigidly to the flap disc and, on the other hand, in articulated fashion to the base of the guide cup. By virtue of the highly sensitive guidance provided by the rollers, the guide cup can move up and down without delay or impact in the loading cylinder, with the result that the control characteristic of the flap is improved.

Patent DE-3322133-A1 (DE)
Title: Sealing ring
Inventor: WOLF FRANZ-JOSEF
IPC: F16L47/08
Filed: 1983-06-20
Abstract: The sealing ring, which consists of a sealing ring section, a retaining ring section and a connecting ring section which connects the two ring sections, for a sleeve having at least two cylindrical steps, in which the two cylindrical steps are connected to one another by means of a conical transition region, is characterised in that the largest external diameter of the sealing ring section of the sealing ring is less than the internal diameter of the cylindrical wide collar section of the sleeve and, at the same time, is larger than the internal diameter of the narrower cylindrical sleeve section, these dimension requirements relating to the unstressed sealing ring. In consequence, the relative thickness of the sealing ring, related to the diameter difference between the two cylindrical sleeve sections, can be markedly reduced, which in turn makes it possible to produce the sealing ring in more cost-effective moulds, with higher productivity, that is to say to achieve a noticeable reduction in the overall costs of the sealing system.

Patent DE-3417426-A1 (DE)
Title: Optical tape length measurement for electronic tape recorders
Inventor: CARLAN SILVIU
IPC: G11B27/26
Filed: 1984-05-11
Abstract: An indication of the length of tape which has already run is very useful for audio tape recorders. In order to be able to realise something like this without mechanical parts, the tape itself must bear the appropriate control information. To protect the useful information on the tape, the control information is applied on the rear side of the tape. This is performed with the aid of marking lines at intervals of one metre, which are sensed by an optical sensor and electronically counted. In this way a methodical position indication of the tape and automatic positioning (by metres and centimetres) are made possible. The contactless method rules out any impairment being caused by abrasion.

Patent DE-3441555-A1 (DE)
Title: Process and device for covering foam boards with non-woven fabric
Inventor: GRAUFF WOLFGANG
IPC: B65B11/10
Filed: 1984-11-14
Abstract: A fully automatic process for covering foam boards with non-woven fabric provides for the individually separated foam boards to be pushed one after the other through a non-woven fabric curtain which is tensioned upstream of a gap lying in the plane of the foam board. As the foam boards are pushed through this gap, the non-woven fabric curtain applies itself to the surfaces of the foam boards on both sides and, after passing through the gap, can be cut off. It is thereby possible to carry out this operation fully automatically within the further processing of foam boards.
