Title: Improvements in or relating to magnetos
IPC: H02K21/36
Filed: 1929-01-15
Abstract: 329,640. Jackson, L. Mellersh-, (Gibson, F. I., and Hayward, G. S.). Jan. 15, 1929. Magneto electric machines. - A magneto has two separate induction systems including dual armatures magnetically in series in a common field and arranged to give independent ignition at separate firing points, means being also provided for adjusting the ignition times of the two systems independently. The form shown comprises two H-armatures 12, 121, Fig. 3, relatively adjustable on a common shaft, one being mounted under each pole of a common bipolar magnet 3 the flux part of which is completed through a " keeper " 2 at the base of the machine. Figs. 2 and 5 show the drive and construction of the distributers, Fig. 6 the interrupters, and Fig. 11 the circuit connections. The magnets rest on segmental pole-pieces 5, Fig. 3, screwed to non- magnetic supports 7, Fig. 5, which centre the keeper 2. The two armature cores 12, 121, Fig. 3, are united by a coupling 19, 20 which allows relative angular adjustment of the cores and carries a fibre or like gear 17 from which the distributer gear 18 is driven. One end of - each secondary 11, 111 is earthed and the other ends are connected to segments 21, 22 in an insulating wheel 23 by wires b, a, the coupling being lined with insulation 21<1> for the passage of the wire a. The segments are connected to the distributors by brushes 220 and wires c, c', and the non-earthed ends of the primaries 10, 101 are connected to the lead-in terminals a', b', Fig. 6, of the interrupter by wires a<2>, b<2> which pass to the interrupter-box through the hollow shaft member 14 at the end of the armature. Each breaker, Fig. 6, comprises an elbow lever 28 normally held by a spring 60 so as to make contact at one end with an adjustable terminal 31 connected by a plate 300 to the secondary terminal a<1>. The other end carries an insulating cam-block 321. Adjustment of the screwed terminals 31 enables the breakers to be set for simultaneous or consecutive sparking in any cylinder. The distributers, Figs. 2 and 5, are mounted on each side of the gear 18, the hollow shaft 181 of which has bearings 351, 35 and lubricating means 353 in a chamber in a spacing- member 352. Each distributing-arm 37, of insulating material, is plugged into the shaft 181 and carries a right-angled brush-holder 38 the brushes 39 and 40 of which bear respectively on an L-shaped piece 42 which is connected permanently to the high-tension winding by the wire c and on a series of contacts 43, 44 - - 48 connected to the spark-plugs. These contacts and the pieces 42 are embedded in insulating blocks 41 which, with the metal plates 49, 491, form the distributer casing.

Title: Optical focusing device
IPC: G02B7/28
Filed: 1975-01-14
Abstract: 1493963 Automatic focusing THOMSON-BRANDT 14 Jan 1975 [15 Jan 1974] 1612/75 Heading H4D To ensure that a read out light beam 3 is focused by a lens L into the smallest possible spot 10 on a data carrier D, irrespective of movement of the carrier, the image of the spot 10, as produced from light reflected from the surface of the carrier and passing back through the lens L (and via mirror M) is distorted by an astigmatic, e.g. cylindrical, lens C, whereby the image varies from a line 26, parallel with the axis of curvature of the lens C and in the focal plane F of the lens L only, to a line perpendicular to said axis of curvature and in the focal plane of the lenses L and C acting collectively, via a circular image 8 of minimum size, in a plane P. In practice the series of images moves with the data carrier, and a quadrant photodetector, placed at the plane P (nominally) detects the shape of the image and produces a signal indicating by magnitude and sign the deviation of the image from the desired circular shape 8. Such signal then readjusts lens L, the positions of the planes of the optics being such that when the desired shape is achieved the image 10 is also of minimum size. The cylindrical lens may alternatively be positioned before the light beam 3 reaches (passes through) mirror M on its way to the lens L, so that the beam is astigmatized before it reaches the data carrier. The spot 10 can then take on the range of shapes (i.e. line, through circle to line) already described, the signal from the detector, positioned as before, adjusting lens L to give the circular shape.

Title: Improvements in and relating to thread guide assemblies for centrifugal can spinningframes
IPC: D01H13/04
Filed: 1956-01-17
Abstract: 780,694. Centrifugal spinning can-thread guides. GARDELLA, A., and GARDELLA, C. Jan. 17, 1956 [Jan. 18, 1955], No. 1633/56. Class 120(2) A thread guide assembly for use in a centrifugal can spinning frame comprises a tubular thread guide shaped to project at its lower or outlet end into a centrifugal can mounted on the frame, and means for imparting a relative reciprocating movement between the thread guide and the can, the outer wall of the thread guide, at least at its end which projects into the can, being rotatably mounted so that it can be rotated by the revolving spinning can in the same direction as the can. In the construction shown a tubular thread guide 5 is inserted in the neck 101 of a spinning can 1 and is idly mounted on ball or like bearings 7 fastened in a vertically reciprocated support bar 6. The inside of the thread guide 5 is provided with a friction surface in the form of a coreless helical rib 8 which serves for smoothing the thread during its spinning and for keeping it centrally disposed inside the guide tube. The thread guide 5 during normal spinning does not revolve but is only reciprocated. If however, there is a knot or bulging portion in the sliver fed to the guide 5 which cannot pass freely through the guide the guide tube 5 is caused to rotate with the spinning can 1 in the same direction and thus prevents the coiled thread G from uncoiling and re-winding on the thread guide 5. In a second embodiment the thread guide consists of a pair of coaxial tubes the outer one. only of which is rotatably mounted. Braking means may be applied to the tube so as to hold it against rotation during normal spinning. Instead of helical friction surface 8 protuberances may be provided on the inside of the tube to act as smoothing means.

Abstract: 846,834. Type printing telegraphy. UNION THERMOELECTRIC CORPORATION. Jan. 16, 1959 [Jan. 16, 1958], No. 1693/59. Class 40(3). [Also in Group XVI] A word-counter comprises a counting mechanism electro-mechanically controlled by the output of a non-inductive device which is connected to the signal line, the output current of the device being responsive to the signal current. In Fig. 7, a low resistance 154, e.g. 15 ohms, is connected in the signal and the voltage developed across it fed to a transistor 100. A pair of electromagnet coils 68 receive the transistor output. A continuously rotating motor 60 drives a first shaft and, through a clutch, Fig. 5 (not shown) a second shaft which carries a member 146, Fig. 6, and gearing which drives the counting mechanism. Assuming that five letters and a space make a word, the second shaft must rotate once for every six characters received, and the member 146 is provided with six equally spaced recesses 152 into which fingers 92 or 94 may fall thus preventing movement of member 146 and stopping the counting mechanism. Movement of the fingers is controlled by the electromagnet 66; when there is a signal on the line armature 72 pivots about stud 74 and moves arm 82. A spring 76 returns the system to the position shown for no line signal. With the direction of rotation indicated a complete code character comprising a start element, code elements, and a stop element, allow the member 146 to make one-sixth of a revolution, the fingers 92, 94 riding on the periphery of member 146 and dropping into the recesses according to the condition of the line.
