Abstract: 263,286. British Lighting &. Ignition Co., Ltd., and Hutton, J. C. Dec. 8, 1925. Magneto.electric machines. - The rotating magnet of a magneto of the stationary armature type has two or more magnets arranged eccentrically to the rotor axis with like poles at the two rotor ends magnetically connected to end pieces which have one or more pole-pieces disposed along the rotor surface parallel to axis of revolution and concentric to the stationary armature pole faces the arrangements being such that the pole shoes are in the spaces between and are located alongside the magnets which are situated nearly on the rotor surface. The magnets may be parallel or inclined to the axis of the rotor. In the form shown in Fig. 1 and in section, Fig. 2, on the line 2-2 thereof, four circular magnets a are parallel to the axis of the shaft b. They are connected by fork-shaped end pieces c each having inwardly-directed tongue-shaped polepieces d, d<1> concentric with the armature poles f. The pole-pieces are connected through a portion of their length by a cylindrical web, shown in dotted lines at g, which enclose the ends of the magnets a and provide a leakage path between the poles of similar size and thus tend to prevent demagnetization. In the rotary magnet shown in Fig. 4 and developed in Fig. 6, the magnets a are inclined to the end pieces c so as to give an increased section at h and i where the pole-pieces d, d<1> and magnets respectively join the end pieces. The magnets may be of any cross-sectional shape or they may be made of V- shaped plates, Fig. 7, bent to a, circular contour. In all forms, the pole-pieces may be integral with the end-pieces, as shown, or they may bo separately formed of laminae and secured to the end pieces by riveting or the like.

Title: Selective calling system
IPC: H04Q9/00
Filed: 1967-07-07
Abstract: 1,133,814. Radio signalling. INTERNATIONAL STANDARD ELECTRIC CORP. 7 July, 1967 [12 July, 1966], No. 31328/67. Heading H4L. A radio network comprises a main station provided with a transmitter and receiver, and a plurality n of secondary stations, each having a receiver and a transmitter, only m of which, variable in number from time to time, are in line-of-sight of the main station at any particular moment, the main station including means for interrogating all the secondary stations cyclically in a cycle of variable length dependent on the number m existing during each cycle, each cycle comprising interrogation periods T1 and T3 of different durations where T3>T1, T3 being used for interrogating and exchanging information with each of the number m of secondary stations, and T1 being used for interrogating without response each of the remaining secondary stations. The network is described in relation to a global observation system in which a main satellite station, for example a polar orbit satellite, interrogates secondary stations which may be balloons, buoys or isolated ground stations, those secondary stations within range replying with information which is stored in the satellite and transmitted later to a ground station. At the start of a cycle the satellite transmits a synchronization signal consisting of a pulse of sinusoidal signal of frequency Fb followed by a similar pulse of frequency Fa. Each secondary station responds to a calling signal in which the number of pulses received characterizes the station and after the sync-signal is transmitted a succession of calling pulses are generated spaced by a time T1 or a time T3 = T1+T2 according to whether the secondary station replies (i.e. is in line-of-sight) or not, the first pulse selecting station 1, the next pulse selecting station 2 and so on. After the transmission of each calling signal the satellite is switched over to receive and if the corresponding secondary station is within range it retransmits the calling signal. When this signal is received at the satellite a time interval T2 for the reception of data from the secondary station is reserved following the time T1 and at the end of this time interval a calling signal for the next station is transmitted. If no reply is received by the satellite the next station is called at the end of period T1. Details of the logic circuitry in the satellite and secondary stations are included, Figs. 3 and 5 (not shown).

Abstract: Packaging material in the form of a flexible and pliable film or foil having good mechanical strength and good sealing tightness characteristics is produced by a method which includes the steps of moving a flexible supporting band over a predetermined path, successively applying to the band at different places in its path at least one coating of a plastic material in fluid condition to form a flexible component layer of good mechanical strength and applying at least one coating of another plastic material of the polyvinylidene chloride type in fluid condition to form a component layer of good sealing tightness characteristics, the surfaces of each coating being still tacky or adhesive when the following coating is applied thereon.  The polyvinylidene chloride may be applied to a thickness less than that required to form a self-supporting film of the material.  The band may be a temporary support, e.g. an endless non-adhesive band of metal, natural or synthetic rubber or cloth, metallized and/or silicone-treated rubber or cloth or silicone-treated metal, and the first coating applied thereon is non-adhesive with respect to the band and the packaging material formed thereon is finally separated from the band; or the band may be a permanent support to which the first coating adheres, e.g. a continuous band of paper or cardboard, cloth, metal foil or cellulose film.  The film of good mechanical strength may be formed from at least one material selected from polyvinyl resins e.g. polyvinyl chloride, polyolefins e.g. polyethylene, polystyrene, polyamides and polyesters.  The film of good sealing-tightness characteristics may be of polyvinylidene chloride, preferably modified with an acrylic resin.  A first coating of polyamide may be applied to the support, a second coating of polyvinyl chloride applied over the first coating, a third coating of polyvinylidene chloride applied and a fourth coating of polyamide applied thereover.  The layer being applied may be subjected to an orientation operation.  The film or foil may be subjected to heating during its formation.  The coatings may be applied as emulsions, granules, powder pastes or solutions with a doctor, or by means of cylinders, or air brush or by extrusion.  The expression "polyvinylidene chloride type" is defined as meaning polyvinylidene chloride and copolymers of vinylidene chloride and vinyl chloride, which may be modified by one or more acrylic resins.
