Abstract: 291,841. Armstrong, Whitworth, & Co., Ltd., Sir W. G., Lee, H. W., and Scott, H. G. A. March 2, 1927. Gunnery calculators.-Relates to director control mechanism for ordnance, torpedo tubes, and other apparatus involving differential correcting devices, and consists in providing between the driving and driven members a hydraulic system in which the fluid between the main input piston 7 and the output piston 10 is influenced by auxiliary correcting pistons such as 23, 35 each of which displaces fluid proportional to a desired function of its controlling member so that the output piston receives a movement in desired function of the combined displacements due to the main and auxiliary pistons. The invention is shown applied to the calculation of data for elevating anti-aircraft guns. The main input piston 7 is operated by the telescope 1 in following the target and communicates movement to the output piston 10 connected with the elevation transmitter 12. The vertical correction for speed of target is applied by piston 35, the logarithms of the time of flight and rate of change of range being added by the pistons 25, 26 and passed on to the piston 35 through an antilogarithmic cam 33. In a similar manner the logarithms of the tangent elevation due to range and height are combined by pistons 14, 15 and conveyed through the anti-logarithmic cam 21 to the piston' 23.

Title: Improvements in or relating to electric switching installations
IPC: H02B5/00
Filed: 1951-03-13
Abstract: 707,895. Air-break switches. SIEMENS-SCHUCKERTWERKE AKT.-GES. March 13, 1951 [Oct. 1, 1948], No. 6064/51. Class 38(5) [Also in Group XXXVI] In a switching installation, particularly an outdoor installation, with main bus conductors and branch conductors which lie at different levels and cross each other, the conductors are interconnected by a plurality of isolating switches of the twopost rotary type, the rotatable connecting terminals of the switches directly supporting the conductors. In Figs. 1 and 1a the isolating switches have rotary post insulators 1 with top caps 3 carrying the switch blades 2. The cap 3 on one insulator of each switch directly carries a connecting terminal 4 which supports a branch conductor 7. To reduce the stresses acting on the other connecting terminal 4 of each switch, it directly carries a bus conductor 6 and is mounted on a carrier element 5 carried by the cap 3. As the post insulators 1 are rotated to open the switches the terminals 4 incorporate a rotary coupling (see Group XXXVI). To reduce the length of the carriers 5, the base supporting the parallel post insulators of each switch may be mounted at an angle on its supporting pillars so as to bring the left hand cap nearer the conductor 6 whilst maintaining the spacing between the conductors 6 and 7, Figs. 2, 2a (not shown). Alternatively, the carrier elements 5 may be dispensed with by mounting the insulators of each switch at right angles to each other on a common base or gear case, Figs. 3, 3a, 4, 4a (not shown). In Fig. 6, the post insulators 1 of each switch are arranged in V-formation on a common gear case 10, the base plate 8 of which is arranged at an angle on a support 12 so that the right hand insulator is vertical. Each switch may be pneumatically operated, in which case the insulators 1 are mounted on shafts 14 having slotted crank arms 16, Fig. 8, co-operating with rollers 17 carried by bridge members 18 interconnecting pistons 31. Admission of compressed air to the cylinder containing the appropriate piston opens or closes the switch, the switch blades being positively held in open or closed position by the engagement of the rollers 17 with the edges of the slots in the arms 16, the edges lying tangentially to the rollers, and by the arms 16 abutting screws 19.

A stereophonic pick-up includes an armature comprising a permanent magnet supported for vibration in a gap provided by pole pieces of two magnetic cores. A pair of U-shaped magnetic cores 1, 2, Figs. 1, 2, are coaxially arranged with their respective polepieces 5, 6 and 10, 11 perpendicular to each other. Each core leg carries a coil of wire 13, 14, 15, 16, coils 13, 14 being connected in series additive relationship and coils 15, 16 also being connected in series additive relationship. Permanent magnet 17 is positioned in the common gap and carries a stylus arm 18 and stylus 19. In a modification, Figs. 3, 4 (not shown), each core has one coil only, the coil being mounted on the core yoke, and the magnet being of cylindrical form. An alternative embodiment, Fig. 7, not shown, is similar to that of Figs. 1 and 2 except that the cores have a common yoke. These transducers are for tracking 45-45 records. In a pick-up for lateral- and vertical-cut stereophonic records, Fig. 5, each core 1, 2 has a secondary gap at its rear to minimise hum. A spherical magnet 17, Fig. 8, co-operates with polepieces 5, 6, &c., of like contour. Cartridge structure.-The transducer is fitted into a moulded plastics case 23, Figs. 10, 13, having terminal prongs 25. Cores are arranged in forward and rear portions of the casing and face each other. The forward core has a yoke 38 and legs 39, 40 on which are mounted coils 43, 44, the core terminating in polepieces 41, 42, Fig. 14. The rear core is similar and includes yoke 45, legs 46, 47 carrying coils 50, 51 and polepieces 48, 49. The polepieces are cast in an epoxy resin block 55 and form a square-sectioned socket in which a ferrule 30, Figs. 10, 12, is friction held. The ferrule 30 is of non- magnetic material and forms part of a supporting spade 26. Within the ferrule is an elastomeric bearing 31 in which a permanent magnet 29 carrying .a stylus arm 27 is mounted. An elastomeric block 28a provides resonance damping of the stylus assembly. The spade is inserted into the core assembly by grasping the serrated wings of the spade and pushing it into the rectangular socket. Two half shells 53, 54, Fig. 14, of ferromagnetic material or " Mumetal  (Trade Mark) shield the cores from stray magnetic fields. In an alternative stylus-armature assembly, Figs. 20, 21, the magnet 61 is held in an elastomeric bearing 62 gripped by a ferrule 59a, and a wire spring 63 of phosphor bronze or beryllium copper at one end is cemented to the magnet 61 and stylus shank, its other end being soldered to a hole 64 in the spade 59. The spring 63 supports the moving system and provides a restoring force. Reference has been directed by the Comptroller to Specification 897,323.
