Title: Device for securing the end connections of rotary windings in dynamo-electric machines
IPC: H02K3/51
Filed: 1929-12-31
Abstract: 339,147. Allgemeine Elektricitõts- Ges. Nov. 13, 1929, [Convention date]. Addition to 338,014. Coils and conductors; cooling.-In a system for securing the end connections of rotor windings by means of wrappings held together by clamps and so distributed that the elements of the winding can expand thermally independently of each other while cooling air can pass freely among the end connections as described in the parent Specification, the clamps are provided with lugs of fan blade form or with recesses for increasing the flow of cooling air. Figs. 1 and 2 show longitudinal and transverse sections, on the planes C-D, A-B respectively, of the end portion 1 of a rotor and the associated end connections 3 of its windings according to the parent Specification. The windings are secured by holders 2 forming a part of the active iron and by axial wedges 4 resting on filler blocks 5, the end connectors being secured by sectional groups of binding wire 6 the turns of which are prevented from slipping by inserted clamps 7. The bindings are insulated from the rotor coils by insulating material 11 which may have central ribs, as shown, to prevent axial movement and which is protected from the binding wire by metallic layers 12. According to the present invention, lugs 8 are formed on the clamps between the bindings and act as fan blades which draw air in from the end of the rotor and expel it radially, as shown by the arrows, from the spaces 9 between the end connections 3. The lugs may be brazed or similarly attached to the clamps or they may be milled out of the solid flanges thereof. Alternatively, they may be replaced by bored passages. In another construction, the fan lugs are made sufficiently wide to cool the whole machine, in which case the end fan 10 on the rotor is unnecessary. In this form, the air gaps 9 in which the blades occur are made wider than the non-ventilating gaps 9<1>. The two sets of short lugs in each gap 9 may be replaced by long lugs provided only on each alternate clamp. In all cases, there is no contact between the lugs of adjoining sets of clamps, so that free axial movement with thermal expansion of the coils is retained.

Filed: 1961-11-08
Abstract: 949,645. Piezo-magnetic microwave generating apparatus. WESTERN ELECTRIC CO. Inc. Nov. 8, 1961 [Nov. 10, 1960], No. 39934/61. Heading H3B. An arrangement for generating microwaves comprises a magnetically anisotropic gyromagnetic body, ferromagnetic, ferrimagnetic or antiferromagnetic placed in a magnetic field and mechanically pulsed by pressure waves at a supersonic frequency whereby the magnetic field in the body is altered in magnitude or direction to an extent and at a speed to produce continuous gyromagnetic precession, the pulsing period being shorter than the relaxation time of precession in the body and the precession frequency being induced in a conductor for application to a load. The crystal 11, Fig. 1, which may be a sphere of yttrium iron garnet, has directions of easy and of hard magnetization which are interchanged by the pressure waves as described with reference to Fig. 2 (not shown) to move the axis and field strength of the effective flux through values as described with reference to Fig. 3 (not shown). The sphere 11 is mounted on and bonded to a pressure focusing core 19, to the spherical base of which is attached a barium titanate transducer 12 energized by an 8 mc/s. source 17. The relaxation time is said to be 10<SP>-6</SP> seconds. The output loop 22 is tightly coupled to the sphere and the whole apparatus may be included in a conductive shield which could take the form of a resonant cavity and provide coupling means for the generated energy. A resonant cavity arrangement coupled to a waveguide via an iris is described with reference to Fig. 4 (not shown) and in this arrangement the crystal is biased with a static pressure. An arrangement using antiferromagnetic material, e.g. cobalt fluoride and, which does not employ a biasing field and in which the orientation of the material is such that the preferred direction of magnetization is inclined to the direction of the line of pressure is described with reference to Fig. 5 (not shown) and in this arrangement which normally has no net magnetic moment electrons precess in the period following deformation. An external biasing field may be used with this arrangement to produce two resonant frequencies.

Abstract: 1327242 Patterns; knitting machines ERAELEKTRONISCHE RECHENANLAGEN STUDIENGESELLSCHAFT FUR WISSENSCHAFTLICHE DATENVERARBEITUNG mbH 19 Aug 1970 [28 Aug 1969] 39935/70 Headings D1C and D1E [Also in Division G3] Textile patterns are displayed on an electronic colour tube 10, whose basis colours are red, blue and green, and are built up from 100x100 squares of colours derived from the basic colour of red, green, blue and white. Basic colours for the squares are selected by keys of an input device 14 and modified by potentiometers of a colour selector 11. A pattern is built up by transmitting one square at a time to the tube 10 as pulses from a data store 25 via a 12 channel multiplex circuit 12, and a three channel multiplex circuit 13 energising the appropriate colour channels of the tube. A pattern is thus created in successive squares line by line, by means of the colour keys on input device 14 which is connected to data store 25. For repetitive patterns, controls 15 for "fill up line", and 16 for "fill up display" serve respectively to iterate a pattern on part of a line, or repeat completed lines. Repetition sequences may be reversed for symmetrical patterns. Controls 17, 18 serve to cancel lines or displays respectively. Controls 19 and 20 provide line or display feeds, manually or automatically. When building up a display, a flashing light indicates the position of the next square to be filled, and for changing a pattern. the light may be moved to any position, and a new colour subsequently inserted. The pattern in electronic form may be transmitted, via format selector 21 to control a loom or knitting machine, or via a tape punch to produce punched or Jacquard tapes, or may be stored in a pulse store 23. A punched tape reader 24 may transmit a complete pattern to the data store 25 and different patterns may thus be blended, or a given pattern matched. Wall paper patterns may be produced as above.-

Abstract: 1,059,020. Electric selective signalling; computer input/output. INTERNATIONAL BUSINESS MACHINES CORPORATION. SeptÀ 24, 1965 [Sept. 25, 1964], No. 40722/65. Headings G4A and G4H. A chain of gas tubes is provided for converting a pulse train into an instantaneous representation and/or vice versa. An operator's terminal for computer input/ output comprises four such chains each arranged so that only one tube can conduct at a time. To send data to the computer, the operator touches keys corresponding to selected tubes to render them conducting and then touches another key to send a " read " signal to the computer. When the computer is ready it sends a clock-pulse train which steps the conducting states in the chains in turn along to the ends of the chains, each step producing a pulse on a common line to the computer. In addition, a pulse is produced on a second line to the computer at the end of each chain. All the tubes are neon tubes and are under their respective keys which are transparent so that the conducting state is visible. If the computer requires to send data to the operator, it lights a tube on the terminal, and on receiving an " accept " signal from the operator, sends pulses to step the conducting states of the chains in turn, from the beginnings of the chains, the pulses relating to the respective chains being delineated by further pulses on a separate line. One terminal may communicate with another in a similar way.
