Apparatus for winding coils of strip material 7 e.g. wire comprises a rotating bobbin support 1 on to which the strip is fed by a guide 8 and independently driven means for moving the.bobbin support approximately at right angles to the line of feed of the strip material at a rate proportional to the rate of increase in external diameter of the coil so that the strip 7 is always fed to the coil in the same plane. As shown, the bobbin support 1 is mounted on a shaft 2 rotatably mounted in a segment-like plate 3 which is.rotatable about a shaft 6, the shaft 6 also driving the shaft 2 via gears 5, 4. The plate 3 is toothed at 12 where it is engaged by a worm-wheel 11 the wormwheel being driven by means which are activated by a change in the external diameter of the coil at a rate proportional to the rate of increase in external diameter of the coil. In this embodiment the support 1 moves along an arc which approxi mates. to a straight line at right angles to the line of feed of the wire. Traversing of the.wire is effected either by the guide 8 being oscillated by the threaded rod 10 or by fixing the guide 8 and oscillating the bobbin along its axis. An arrangement for interleaving sheets e.g. of insulating paper between the layers of the coil may also be provided.

Abstract: 869,365. Electrical measuring systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 20, 1958 [March 25, 1957], No. 9721/57. Class 40 (1). [Also in Group XL (c)] Apparatus for measuring the speed of rotation of the shaft of an I.C. engine comprises a capacitor having a voltage limiting device connected across it, the capacitor being alternately charged through a circuit and discharged through a transistor under control of the contact breaker associated with the ignition coil. In Fig. 2, the transistor T is cut-off when the contact breaker CB is closed. This allows the capacitor C2 to charge via resistor R1, diode D4 and an instrument M until the voltage across the Zener diode Z is reached when the charge is limited by the catching diode D5. Capacitor C2 discharges through the transistor T each time the contact breaker CB opens, the instrument M being by-passed for discharge current by the diode D3. Resistors R6, R7, R8 are provided to compensate for variation in the charging current with supply voltage variation. In a simpler transistor circuit (Fig. 1, not shown), both the charge and discharge current is measured by a rectifier instrument, the Zener diode Z being connected across the collector and emitter electrodes.

Abstract: 595,398. Blank-punching. ARNOLD, C. (Bliss Co., E. W.). June 17, 1943, No. 9725. [Classes 83 (ii) and 83 (iv)] In a machine for performing successive operations on an intermittently fed strip of material s means for detecting inaccurate feed comprises an electric switch 15 and a feeler 25 actuated in timed relation with the operative cycle of the machine and responsive in movement to the position of said strip so that, if this has not been fed correctly, it operates the switch 15. This is mounted on a table 14, Fig. 4, of a member 13 which is pivoted at 12 to a bracket 10 and is biassed in a clockwise direction by a spring 22 but can be oscillated counterclockwise by an adjustable cam 19 thereof being engaged by a pin 35 on the press head 34 which carries the punches &c. for operating on the strip s. A member 24 also pivoted at 12 carries the feeler 25, adapted to engage a series of holes 5 in the strip s and is normally held in fixed relation to the member 13 by a spring 30 tending to move it counterclockwise, its arm 24a engaging under the table 14 of the member 13. If the strip s is not fed the correct distance the feeder 25 cannot enter the hole 5 when the member 13 is moved counterclockwise by the pin 35 and the member 24 is thus moved, relative to the member 13, counterclockwise and its set screw 31 engages a pin 33 of a switch 15 to cut off the current and stop the press. In a modification, the member 13 may be tilted during both up and down strokes of the press head by using a pin 35<1>, Fig. 7, with an enlarged head 36 and a cam 19<1> with inclines 20<1>, 20<11>.

Abstract: 922,532. Travelling wave tubes. MULLARD Ltd. Feb. 8, 1960 [March 20, 1959], No. 9756/59. Class 39 (1). A travelling wave tube has a magnetic focusing system comprising a main solenoid 1, Fig. 2, or permanent magnet to produce a longitudinal magnetic field and an auxiliary coil or coils 2A, 2B, 3A, 3B, providing an auxiliary focusing field substantially perpendicular to the main field so that the resulting field can be coaxially aligned with the travelling wave tube. There may be a single pair of coils intersecting the axis or two pairs of coils 2A, 2B, 3A, 3B arranged around the axis perpendicularly to one another. One coil of the pair or one coil of one pair can be omitted; in these cases the remaining coil or coil of the pair can be rotated as one of the adjustments. The other adjustment is separate variation of the current in each coil or each pair of coils by variable resistances in series with the coils. The auxiliary coils may be inside the solenoid. If a permanent magnet is used the magnetic yokes have a shielding effect with respect to the correcting field so the auxiliary coils are located within the yoke and magnet system.

Title: Improvements in and relating to apparatus for effecting energisation of an electric circuit with unidirectional impulses
IPC: B23K11/24
Filed: 1938-03-30
Abstract: 513,080. Converting; supply systems for welding &c. circuits. BRITISH THOMSONHOUSTON CO., Ltd. March 30, 1938, No. 9777. Convention date, March 31, 1937. [Classes 38 (ii) and 38 (iv)] In supplying a load such as a welding or magnetizing circuit 1 with unidirectional current impulses by means of a transformer 3 the primary of which is energized through a valve 5 by positive impulses from an A.C. supply 2, the primary winding is, prior to each working impulse, energized by a negative impulse through a reversely-connected valve 13 so that the working impulse in the secondary is produced by a flux D, Fig. 2, which falls from a value b to a value d of the same polarity, and thus no reverse current is produced in the secondary circuit by decay of flux at the end of the working impulse. The valve 13 has a control circuit 53 primarily energized by a transformer 54 fed from the A.C. supply 2, but is arranged to be rendered inoperative for a period after the transformer 3 has received a working impulse by reason of a charge on a condenser 59 applied by a transformer 60 connected across the primary of the transformer 3. The valve 5 is of the immersionigniter type and is supplied with starting potential at the commencement of each working impulse by a transformer 32 controlled by a valve 28. The latter is supplied with anode voltage from a condenser 21 but is normally maintained inoperative by grid bias from a condenser 23 maintained constant by a glow discharge tube 24, the condensers 21, 23 being continuously changed from an auxiliary rectifier 26. Each working impulse is initiated by cutting out a resistance 37 (by switch 49) from the grid circuit of valve 28 thus causing the amplitude of A.C. potential from a transformer 38 to exceed the bias from condenser 23 and rendering valve 28 conductive to apply a starting impulse to valve 5. The resulting energization of transformer 3 with a positive impulse causes, through a transformer 50 connected across primary of transformer 3, a condenser 45 to charge to a blocking potential which maintains valve 5 inoperative for a period determined by resistance 37 through which condenser 45 discharges. Thus, since valve 13 is similarly biassed off by condenser 59 and resistance 58, time is available for removal of work from the secondary circuit of transformer 3 before the cycle is repeated.
