Title: Improvements in or relating to high-tension transformers
Inventor: HORCHER WERNER
IPC: H01F27/32
Filed: 1958-07-15
Abstract: 877,587. Transformers. TRANSFORMATORENWERK K. LIEBKNECHT VEB. July 15, 1958, No. 22660/58. Class 38 (2). A high voltage transformer is provided with insulating angle rings 4, 5, 6, 7 (Fig. 1) shaped as shown, fitted into the layer insulation 3 and spaced by distance pieces 8, 9, 10 to subdivide the oil path. As shown in chain lines for ring 4, the outer part of the angle rings may be steeper between core legs. Insulating walls 11 are provided between core legs only. Cooling ducts 2 are provided. Fig. 2 shows an arrangement in which the cooling oil is circulated by pumping. The rings are made of layers of paper or pressboard which may be varnished and hardened by gluing partially or to a varying degree so that, for example the inner parts which are most highly stressed electrically, may be soft, while the outer edges, which are more stressed mechanically, are fully hardened.

Title: Method and a nozzle for producing interlaced yarns
IPC: D02J1/08
Filed: 1973-05-11
Abstract: 1428257 Yarn interlacing nozzle RHONEPOULENC-TEXTILE 11 May 1973 [26 May 1972] 22699/73 Heading D1F A method of producing an interlaced yarn comprises feeding at least one multifilament yarn through an interlacing zone, while tensioned between two yarn guides, and continuously subjecting the yarn to the action of at least one jet of fluid having a flow disturbed by at least one freely movable mechanical means, as it passes through the interlacing zone. In a preferred embodiment, the yarn is passed through a chamber 1 formed in a body 2 having coaxial inlet and outlet openings 5. Fluid, preferably compressed air, is introduced into the chamber I by at least one jet 4 fed from duct 3. The jet 4 is preferably tangential to the chamber 1, several jets may be provided, which may or may not be coplanar. The means for disturbing the flow is preferably in the form of balls 6, or cylindrical or barrel-shaped rollers. In a further embodiment, the duct 3 opens into a plenum chamber 8 which supplies fluid to angularly directed jets 4 opening into a chamber 1 containing one or more balls 6. The balls 6 are located in an annular chamber 1 bounded by walls 2 and 9. The wall 9 surrounds a yarn passage and has one or more holes 10, which may be radially directed and coplanar with duct 3 and jets 4, for feeding fluid to the yarn passage to interlace the individual elements of the yarn. Several examples illustrating use of variations in number of jets, yarn speed, fluid pressure, mobile elements are given. For Figures see next column

Title: Adjusting means for electrical transmission lines
IPC: H01P5/04
Filed: 1944-11-16
Abstract: 599,804. Electric resonators. PHILCO RADIO & TELEVISION CORPORATION. Nov. 16, 1944, No. 22701. Convention date, Nov. 17, 1943. [Classes 40 (iii) and 40 (v)] A coaxial transmission line is electrically lengthened, without the introduction of impedance-mismatch, by the insertion of an adjustable section suitably dimensioned. Thus in a length-adjusting device of the trombone type, the incoming and outgoing lines 8, 9 are each coupled through a quarter-wave section 6, 7, to a sliding section 4, and the characteristic impedance of the coupling sections 6, 7, is the geometric mean of those of the sections 4 and 8, 9. The inner conductor of the sliding section 4 passes inside, and its outer conductor outside, the corresponding conductors of the coupling sections 6, 7, so that the length and characteristic impedance of the latter remains constant in spite of the adjustment of the sliding section 4. A straight section may be similarly constructed, Figs. 2, 5 (not shown). The device may be used in the feeder between a television transmitter and a dipole aerial, Fig. 1 (not shown).

An apparatus for charging a multi-cell battery without large variations in the terminal voltage comprises a charger C1 connected across the whole battery and supplying the mean current of a load X and a second charger C2 connected to one or a small number of cells in sequence through a stepping switch comprising a ratchet R and a pawl T operated by a coil M energized by normally closed contacts F of a relay G, F. The connections to the battery are changed by arms P, N and contacts K. Additional contacts E, operated by an extension U of the pawl, and H operated by a slowrelease relay coil D step the mechanism over an off contact L to which may be connected a counting device. The charger C2 may be of the constant-voltage type, with the coil G in series, or a constant-current or combined type with the coil G connected across its terminals. Each cell may be provided with a catalytic converter to recombine the gases produced by electrolysis. To increase the charging rate of C1 after a mains failure, the charger C1 and load X may be switched normally or automatically across part of the battery, a rectifier being connected across the switch to preserve continuity of current flow during changeover.
