Patent DE-3325387-A1 (DE)
Title: Test standard for checking length-measuring instruments
Inventor: SCHUESSLER HANS-H DIPL ING DR
IPC: G01B5/00
Filed: 1983-07-14
Abstract: The invention relates to a test standard for checking length-measuring instruments, which is formed from a support body and a plurality of end-measure pieces or shaped elements which are held in a defined position thereon. It is provided for the forced temperature stability of the test standard that a fluid under forced temperature stability can be applied to the essential, size-determining, supporting parts or wall parts of the support body in a thermally conductive fashion. The temperature-stabilising fluid is temperature-stabilised in a separate device within narrow limits, for example to 20 +/- 0.1 DEG C, and conducted at a high speed and/or rate of circulation through a corresponding duct system in the region of the supporting parts or wall parts. A two-dimensional distribution of the temperature-stabilising energy can be performed with the interposition of so-called heat tubes. Support bodies, constructed in the manner of a lattice tower, of stepped end measures can be temperature-stabilised by constructing the longitudinal bars in tubular form in the region of the cross-sectional corners, through which the forced temperature-stabilised fluid can flow.

Title: Cutter head for wood working
Inventor: WASCHEROH HEINRICH
IPC: B27G13/10
Filed: 1983-07-27
Abstract: A cutter head for wood working has a body (1) with keyways (2) widening radially inwards. An interchangeable cutter (3) is firmly clamped in each keyway (2) by a gripping wedge (6). Screwed into the gripping wedge (6) are clamping screws (7) which are supported on the root of the keyway (2). To release the gripping wedge (6), a forcing screw (11) is screwed through a through hole (8) in the gripping wedge into a tapped hole (9), in alignment with the through hole (8), in the cutter-head body (1) and presses the gripping wedge (6) to the inside. It is therefore unnecessary to knock the gripping wedge (6) to the inside in order to release it, so that damage and the risk of injury are avoided. <IMAGE>

Title: Machine for palletising reels made from webs
Inventor: POLLENDER HANS
IPC: B65G65/00

Patent DE-3417255-A1 (DE)
Title: Holder for pads
Inventor: SPEER HERBERT
IPC: G02C5/12
Filed: 1984-05-10
Abstract: The invention relates to a holder for pads on metal spectacle frames, consisting of a support with an anchoring foot for the pad, which support can be plugged onto the end of the web arm, by means of a pouch-like recess, and connected thereto. The aim here is to provide a simple and reliably mountable pad holder which also permits simple replacement without damage to the nickel skin and, moreover, manages without further additional parts, as well as allowing in the mounted state the required mobility for matching to the nose flanks of the carrier. This is achieved in such a pad by inserting spring padding at the base of the blind hole with an oblong cross-section and providing at right angles thereto above the level of the spring padding undercuts behind which the web arm end, which resembles a hammer head, is anchored resiliently on the narrow head side by being inserted with the wide side and twisted. The action of the spring padding leads without the mounting and demounting of third parts to the achievement of a resilient latching and unlatching of the pad connection in conjunction with a desired mobility for the purpose of matching the pad to the nose seat. <IMAGE>

Title: Device for the rapid dissipation of an excessive voltage on a capacitor in the case of reactive volt-ampere compensation installations
Inventor: SCHWARZENAU REINHARD DIPL ING
IPC: H02J3/18
Filed: 1984-05-12
Abstract: In the case of a device for the rapid dissipation of an excessive voltage on a capacitor which is connected in series with an input inductor and an electronic switch between the supply leaves of an AC voltage network, and whose connection is used for the purpose of compensating, in the network, for inductive reactive volt-amperes caused by loads having a reactive volt-ampere requirement which changes severely with time (pulse-power loads) it is intended to prevent unnecessary flickering effects in the network. This is achieved in that a series circuit is connected in parallel with the compensation capacitor (CK), which series circuit consists of a saturable inductor coil (L), a resistor (R) and two or more zener diodes, or other electronic components having a similar effect (non-linear relationship between the current and voltage) (Z1, Z2), which are connected in series with respect to one another. <IMAGE>
Patent DE-3422429-A1 (DE)
Inventor: KOENTGES GERHARD
IPC: B29C39/06
Filed: 1984-06-16
Abstract: To control the intermittent movement of a conveyor belt or carousel, fitted with molds, in a unit for the manufacture of moldings from multi-component plastics, an intended/actual value comparison of the speed of the conveyor belt or carousel as a function of the distance of the molds from fixed devices for filling, demolding and similar operations of the molds is carried out so as to provide control signals for the electric motor. The actual value is determined from a signal voltage generated in correspondence with the rotary movement of the electric motor. The signal voltage is additionally, and in parallel to the speed regulation, converted to electric pulses which are summed in their time sequence, as a function of the movement steps of the conveyor belt or carousel, and are compared with a predetermined master function which can be varied.
Patent DE-3425096-A1 (DE)
Title: Open-end friction-spinning device
Inventor: STAHLECKER FRITZ
IPC: D01H4/16
Filed: 1984-07-07
Abstract: In an open-end friction-spinning device having two rollers arranged next to one another and forming a V-shaped nip serving as a yarn-forming point, there is a suction device which holds the forming yarn in the V-shaped nip. The suction device sucks up more air than is needed for transporting the fibres from the opening roller to the V-shaped nip. There is therefore an air-supply device which generates an additional airstream directed to the V-shaped nip and, furthermore, is utilised for improving the detachment of the fibres from the opening roller and for the transfer to the V-shaped nip.

Title: Circuit arrangement for primary-pulsed switched-mode power supplies
Inventor: BERTRAM RALF DIPL ING
IPC: H02M3/338
Filed: 1984-07-24
Abstract: In a primary-pulsed switched-mode power supply, the output voltage is already compared in the secondary circuit (3) with a reference voltage (35) and is used for providing driving pulses for the power transistor (14). These control pulses for the power transistor are transmitted from the secondary side (3) to the primary side (1) via a network (22) having a control transformer (22). In this case, the control transformer is used for potential isolation. In order to ensure a suitable current supply (38) on the secondary side (3) even during starting, the network voltage (11) is coupled from the primary side (1) to the secondary side via high-voltage-resistant capacitors (23, 24, 25) and is rectified (37) there for the starting process. <IMAGE>
