Title: Improvements in or relating to pawl and ratchet mechanisms
IPC: H01H63/20
Filed: 1929-12-16
Abstract: 344,949. Ratchet gearing. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and FORCEVILLE, E. A., 23, Fossil Road, Lewisham, both in London. Dec. 16, 1929, No. 38491. [Class 80 (iii).] In a pawl and ratchet type electromagnetic selector, the ratchet is moved forward one step on the energization of the electromagnet and a second step on the release of the magnet. Alternatively two magnets acting on the same armature may be employed, the ratchet moving forward one step when the armature is pulled in one direction and a second step when it is restored by the action of the second magnet. The invention is described as applied to a telephone switch of the type desscribed in Specification 323,892, [Class 40 (iv), Telephones &c.]. The ratchet bar 7 is moved by two pawls 14, 15 which are hinged respectively at 18 and 19 to a link 16. Springs at 18, 19 hold the pawls into contact with the ratchet bar. The link 16 is pivoted at 17 and is provided with a hooked end 20 which engages with the armature 3 of an electromagnet 2. When the magnet is energized the link 16 swings about 17 in an anticlockwise direction moving the pawls towards each other, the pawl 14 sliding over the teeth and the pawl 15 moving the ratchet forward one tooth. When the current is removed the magnet releases and the armature is restored by the spring 5 rotating the link 16 in a clockwise direction, moving the pawls away from each other, the pawl 15 sliding over the teeth and the pawl 14 moving the ratchet forward one step. On release, the pawls 14, 15 and the holding pawl 21 are lifted from the ratchet, which is restored by the action of a spring. The two pawls 14, 15 may engage separate sets of teeth which may be on opposite sides of the ratchet bar. The cores of the electromagnets may be adjusted lengthwise to alter the air gap.

Abstract: 1,110,340. Permanent - magnet alternators; securing coils. GARRETT CORPORATION. 10 Sept., 1965, No. 38767/65. Heading H2A. In a planar air-gap machine with axiallyspaced rotary field structures, one of the structures has flux-producing means permanently magnetized in the axial direction and another is magnetically passive, providing a flux return path, the armature winding comprising a coil wound around one of the field structures with a portion of it located in the air gap. As shown in Fig. 8, an axially-magnetized annular magnet or set of magnets 3 (e.g. of alloy or barium ferrite) is secured to an iron flux-return disc 2 mounted on a shaft 1; spaced along the shaft is a further iron disc 2<SP>1</SP> providing the return circuit for flux across the planar air gap. Preferably, the assembly 2, 3 is encased in a shell 6, 8 (with thickened hub 7) of copper or aluminium to provide damping; preferably, fan blades 10 extend from back plate 8. Disc 2<SP>1</SP> is similarly clad and may also have fan blades. (For low-speed machines, only the damping on 2<SP>1</SP> need be present). The damping on disc 2<SP>1</SP> may be constituted by forming the air gap face of the disc into a pattern of axiallydirected protuberances, and casting aluminium or alloy in the intervening spaces, the damping being continued around the edge and rear face, where fan blades are provided. The air gap face thus formed may be further covered by a thin sheet of magnetic material to collect and distribute the flux uniformly (Figs. 6, 7, not shown). A stator comprising two coils 22 is fitted around the assembly 2<SP>1</SP>, 14, 15. Each coil is wound from round wire, the wires of each layer being located in the grooves between wires of an adjacent layer; the winding is then bonded. The outer portions of the two coils may be mounted between a plate 29 and vertical bars 28 of non-magnetic material, Fig. 13. In alternative coil-mounting arrangements, two non-magnetic brackets, which may be combined in one piece, are cemented to the coil, and the assembly is supported in a jig for drilling mounting holes in the brackets (Figs. 14, 15, not shown); alternatively, a plastics mounting-block may be used instead of brackets. Preferably, the ends of the coils are curved, in the plane of disc 2<SP>1</SP>, to follow the circular contour of the disc. For a two-phase machine two coil sets at right angles are provided, and for three-phase, three sets at 60- degree intervals.

Title: Communication system
IPC: H04J1/06
Filed: 1965-09-13
Abstract: 1,091,599. Radio signalling; automatic gain control. NIPPON ELECTRIC CO. Ltd. Sept. 13, 1965 [Sept. 11, 1964], No. 39015/65. Headings H3Q and H4L. A multichannel communication system comprises a plurality of carrier frequencies, e.g. 1-18, Fig. 5, divided into groups and amplified in a common amplifier, each group being accompanied by a pilot frequency P1-P5 for level control purposes. In addition, there is a reference frequency Pc for the whole system; according to the invention the pilot frequencies are grouped together adjacent to the reference frequency, being nearer to it than is any of the carrier frequencies. The arrangement is described as applied to a system in which a number of ground stations 31-34, Fig. 6, are in communication with one another via a remote relay station 35, e.g. a satellite. Each ground station comprises a number of modulators, e.g. 37A-37C whereby a plurality of signals are modulated on to a group of carriers of different frequencies, which are combined in a combiner 41. together with a pilot signal from source 39. They are then shifted to a corresponding group of transmitting frequencies by converter 45 and local oscillator 43 and applied to aerial 51 via variable attenuator 47 and power amplifier 49. Common relay station 35. This comprises a receiving aerial 70, frequency converter 71 and local oscillator 72 converting the incoming signals to an intermediate frequency for amplification in I.F. amplifier 73, after which the signals are converted to new transmitting frequencies by means of converter 74 and local oscillator 75. Before application to transmitting aerial 79 via power amplifier 78 a reference signal is added in by means of reference source 77 and combiner 76. Reception.-Each ground station also includes a superheterodyne receiver connected to receiving aerial 53 and comprising frequency converter 57, local oscillator 55, I.F. amplifier 59 and demodulators 69A-69C, for the carriers required to be received. In addition, filters 61, 63 respectively, coupled to the I.F. amplifier select the reference signal inserted at the relay station and the pilot frequency peculiar to the particular ground station. These are compared in comparator 67, the level of the reference signal being adjusted as necessary by means of attenuator 65; any difference between the two causes a level correcting signal to be applied to the variable attenuator 47 in the corresponding transmitter. The arrangement is intended to compensate for non-linearity in the power amplifier 78 in the common relay station, which emphasizes any fortuitous discrepancy between carrier signal levels; the reference and pilot signals are transmitted at a lesser amplitude than the carrier signals, to conserve power.
