Title: Improvements relating to electrical pulse storage apparatus
Inventor: URQUHART-PULLEN DAVID IAN
IPC: H04B14/02
Filed: 1961-02-17
Abstract: 1,015,861. Capacitative data stores. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 8, 1962 [Feb. 17, 1961], No. 5960/61. Heading G4C. [Also in Divisions H3 and H4] In a circuit for pulse storing or pulse lengthening, Fig. 1, when negative-going amplitude modulated pulses - V s  are supplied between terminals X and + V B , capacitor C is charged via diodes D 1 , D 3  to a potential dependent on the pulse amplitude, the diode D 2  being held non-conducting by a potential - V R  on the terminal Y. The potential + V B  is just sufficient to compensate for the forward voltage drop of the diode D 3  to enable it to switch on quickly. At some time after the input pulse a positivegoing interrogating pulse V R  applied at terminal Y will cause the diode D 2  to conduct and discharge the capacitor C through the load resistor R to provide an output signal. A number of these units are connected together to form a store in which it is possible to read out from one unit and simultaneously write into a different unit, an additional diode being connected between each capacitor and a common load circuit to prevent mutual interference, Fig. 2 (not shown). In Fig. 3 a plurality of store units are arranged to be scanned, timing pulses being applied at the left-hand terminal and the signal at the top terminal. An input counter scans the gates M1 to M4 and signal pulses are passed to the corresponding storage units S1 to S4. An output counter via isolating amplifiers supplies interrogating pulses for reading out the information stored in the units S1 to S4. The timing pulses are supplied to the input and output counters via gates G-IN and G-OUT respectively, the gates being alternately switched by a bi-stable device which is triggered each time the input or output counter completes a scan. The apparatus is suitable for use in a binary system or in amplitude modulated pulse systems. In the arrangement of Fig. 3, the input signal could be continuously variable. The circuit of Fig. 1 may be used to convert length-modulated pulses to amplitude-modulated pulses.

Title: A system of pole-changing for polyphase induction motors
IPC: H02K17/14
Filed: 1922-03-01
Abstract: 176,365. Kand¾, K. March 2, 1921, [Convention date]. Motors, controlling.-A polyphase induction motor has an 8n-pole 3-phase winding which is adapted for alternative use as a 6n-pole 4-phase winding, all coils being used in each system of running. Each coil in any phase in the 3-phase arrangement overlaps two coils in the other two phases and when the machine is changed to 4-phase running these coils which are spaced apart by 120/n degrees are connected together and two of the resulting coil groups, each containing 3n coils and spaced with respect to each other by 60/n degrees, are connected to a pair of terminals of the 4-phase supply. Fig. 1 shows a motor for 8-pole running on a 3-phase supply which is brought to sliprings a, b, c, or for 6 poles on a 4-phase supply from a generator I, II - - VIII. In this example, n is unity. With 3- phase power supplied at a, b, c, 8 poles are produced by the current distribution indicated in the coils A1, A2 - - A8 by the single arrowheads. For 6-pole running, the rings a, b, c are disconnected from the 3-phase supply and 4-phase power is supplied to the rings 1, 2 - - 8 bv means of switches. The motor connections between the terminals of phase I - - V consist of two groups of three coils A8, C2, B5, Fig. 2, shown in heavy lines in Fig. 1, and B1, C3, C6 shown in heavy dotted lines grouped in parallel between the rings 1 and 5 as common terminals, and the rings a, b, c respectively acting as neutral points. The three coils of each group are 120‹ apart and the two groups are displaced by 60‹, thus giving a symmetrical 6-pole field, as shown by the double arrowheads. The 6-pole 4-phase winding may be further converted into a 12-pole 2-phase winding as described in Specification 161,973, by connecting rings 1, 3 and 2, 4 to the terminals of one phase and rings 5, 7 and 6, 8 to those of the other phase. The 2-phase current may be taken from points 90‹ apart on the 4-phase source.

Hatches. - A fabricated cover for ships hatchways which dispenses with the use of fore- and-afters comprises metal sections s<1>-s<3> which may be of roof-section which facilitates their stowage in superposed position when off the hatch, and which extend from side to side of the hatch. The sections are framed at their edges by bulb-angles c, channels d associated with surface plates f. The ridge is provided with a capping b and the plating adjacent thereto is stiffened by transverse skeleton frames c. The sections are positioned on the coaming t<1> by internal plates l. A salient feature of the construction is rendering the cover watertight by gaskets employed both at the abutting edges of the sections and between the sections and the hatch coaming, means being provided to ensure that the gaskets are pressed simultaneously against both abutting surfaces. In the case of abutting sections, a gasket n, Fig. 8 positioned by a rabetted casting o, is pressed against an abutment on the adjacent section by a cam-actuated pressure bar p, the sections being locked by a bar h pivoted in an eyeplate i and retained by a wedge k passed through a second plate j. In the case of the joint between the sections and the coaming, the gasket r, Fig. 7 is pressed against both adjacent sections by a bar y controlled by wedges z, looking being effected by cleats w mounted with a certain degree of vertical movement in the channels d and co-operating with catches u hinged to the coaming, the final locking being effected by wooden wedges. In a modified form of hatch cover shown in Fig. 13 the sections, which are jointed together are furnished with rollers mounted in adjustable boxes running rails p, these rails being provided with a vertical extension which ensures that some ot the sections are stowed in a vertical position when the hatch is opened.
