Title: Improvements in or relating to distant control systems
Inventor: JEANS GERALD LESLIE GORDON
IPC: G08C19/48
Filed: 1955-10-27
Abstract: 808,567. Electric selective signalling systems. GENERAL ELECTRIC CO. Ltd. Oct. 24, 1956 [Oct. 27, 1955], No. 30768/55. Class 40 (1). A distant control system in which a secondary member is arranged to be moved in response to movement of a primary member includes a multi-position switch of the make-before-break type arranged to be actuated by the primary member, a set of inductances connectible to a single-phase alternating current supply through the multi-position switch in such manner that for each position of the switch predetermined voltages are induced across the set of inductances and that movement of the switch from one position to another does not cause a shortcircuiting of the alternating current supply, and a resultant field apparatus having its rotor or stator connected to one set of inductances in such manner that the magnitude of the resultant magneto motive force produced in the rotor or stator is constant for all positions of the switch and the direction of the resultant magneto motive force varies with variation in the position of the switch and having its stator or rotor respectively connectible to a singlephase alternating current supply so that the secondary member which is mechanically connected to the rotor sets itself in a position corresponding to the position of the switch. A selsyn 7, Fig. 1, having a star-connected threewinding stator 9, 10, 11, Figs. 3a, 3b, is controlled by a 12-position switch 3, Fig. 1, which by differently connecting a single-phase A.C. voltage (terminals 18, 19) via three centretapped chokes 15, 16, 17, Figs. 3a, 3b (these Figures showing two of the 12 possible connecting arrangements) causes the rotor 8 of the selsyn-which carries a single winding fed with A.C. current-to assume 12 different positions. A development of the switch contacts is given in Fig. 2 (not shown), Figs. 3a and 3b corresponding respectively to switch positions 1 and 2. As shown in Fig. 1, the switch 3 is arranged to be driven either manually or by the motor through reduction gearing and the selsyn 7 is arranged to drive a multi-contact switch arrangement 5, also through appropriate reduction gearing. It is stated that the resultant magnetic field created by the stator in the selsyn is of substantially constant magnitude and that the windings could be delta-connected. Damping of any oscillations of the rotor of the selsyn can be effected either by a freely mounted flywheel and friction pads or by eddy current means.

Title: Improvements in magnetic data storage devices reading and head therefor
IPC: G06K7/08
Filed: 1963-08-02
Abstract: 1,101,183. Magnetic recording and playback; digital data storage. MOLINS ORGANISATION Ltd., and D. W. B. MUIR. 29 July, 1964 [2 Aug., 1963], No. 30768/63. Headings G4C and G5R. In a binary data-storage unit wherein discrete storage elements, e.g. magnetic pins 10 spaced around the periphery of an insulating disc 1, Fig. 2, are selectively magnetized in one sense or the other, the read-head 9 comprises a core 12 having a gap which is substantially closed when a pin 10 is disposed therein. A battery 14 passes a biasing current through the read-head winding 16 which preferably just saturates the core 12 when a pin is absent from the core gap. A binary " 0 " magnetizes a pin in the sense such that when read the flux through the readhead core 12 is slightly increased, but as the core is already saturated this has substantially no effect. When a binary " 1 " is read, however, the oppositely magnetized pin causes the core magnetization to drop below saturation thus markedly increasing the inductance of the winding 16. At this value of the inductance, the tuned circuit, formed by a capacitor 18 and the winding 16, resonates with the output of a generator 20 so that the A.C. voltage appearing across the winding 16 rises to a much higher value and is fed over the output lines 21 as the read out signal. Alternatively, the D.C. bias may be such that the core flux is substantially one half that required for saturation when no pin is present in the core gap, the tuned circuit 16, 18, under these conditions, resonating with the generator output. When a pin 10 magnetized in the same sense as the biasing flux is read, the core saturates and the A.C. output voltage across the winding 16 drops as the tuned circuit goes out of resonance, but when an oppositely magnetized pin is read, there is some cancellation of the biasing flux, but the pin remains in resonance. The write-head 8 is similar in construction to the read-head, the write-head winding 13 being energized in one sense or the other over appropriate circuitry 15. The read-head may be " followed " by an erase head which " switches " all pins 10 to the binary " 0 " condition. A combined read-write head may be used. Groups of discs may be mounted on a common shaft for the storage of multi-digit numbers.

In apparatus for feeding material, e.g. woodchips, into a conveyer of the kind comprising a rotor with blades 14, the air inlet 3 lies wholly, or largely, within the cross-sectional area swept at the inlet end by the blades during their rotation, the outlet 4 lies at least partly outside the cross-sectional area swept by the blades at the outlet end, and between the inlet and outlet the casing 1 for the rotor is shaped to form a channel 17 which terminates in the outlet. The hub 13 increases progressively in diameter from the inlet to the outlet along a curved line so that the channel 17 is of substantially uniform cross - sectional area throughout its length. The ends of the casing 1 are closed by plates 6, 7. The inner side of the trough at the inlet end lies radially outside the line generated by the outer edges of the rotor blades and through the gap 18 so formed air can pass from the inlet 3 to the channel without passing through a pocket of the rotor. A clearance 21 is provided between the plate 6 and the end of the rotor to permit a slight flow of air from the inlet 3 to prevent particles of material entering between them. The length of the inlet 2 to the casing is slightly less than that of the rotor chamber and the overhanging shoulders 26, 27, thus provided prevent feeding of the material directly against the ends of the pockets. One longitudinal side of the inlet 2 is provided with a shearing edge 28 which is inclned to the rotor axis. The other side of the inlet may have a similar shearing edge 29 which comes into action when the rotor is driven in the opposite direction.
