Title: Magnetic device for computing or control systems
IPC: H03K17/84
Filed: 1958-09-19
Abstract: 871,829. Magnetic storage devices; circuits employing bi-stable magnetic elements. HUGHES AIRCRAFT CO. Sept. 19, 1958 [Nov. 29, 1957], No. 30104/58. Class 38 (2). [Also in Group XXXIX] A magnetic device for computing, gating, memory &c. systems comprises two thin magnetic films 32, 34 (Figs. 6 and 7) with a number of insulating and conducting films interposed therebetween, the films 32, 34 being joined at their edges to form a closed magnetic circuit around the control conductors 40 and 44 and the clock pulse input conductor 48 from which trigger conductor 52 is separated by a conductive layer 36 acting as an electrostatic screen. The trigger winding 52, 58 (which provides the output) is formed into a loop round magnetic film 34 by providing above 34, and insulated therefrom, a conducting layer 58 with its righthand end engaging the end of conductive layer 52. To avoid interwinding capacitance a screening layer 36 is connected to magnetic films 32, 34 and to earth or to a common potential point having a very low source impedance. The metal films may be produced by vacuum deposition, electro-deposition, or electrophoresis and the insulating films by silk screening techniques, inking, etching or printing. The use of the device is described for a conventional magnetic gating scheme in which it functions as a gate, a clock pulse (Fig. 2, not shown), producing an output pulse for triggering a transistor, arranged as a bi-stable element, only when no currents are applied to any of the control windings. The series connection of all the trigger windings of a plurality of similar gates is said to define an " or " circuit. The common portions of this arrangement such as the series connections of the trigger windings may be deposited as one continuous layer on the soft glass substrate 30.
Patent GB-301456-A (GB)
Abstract: 301,456. Halperin, H., and Miller, K. W. Nov. 30, 1927, [Convention date]. Protective arrangements; systems depending on static transformers.-In alternating current polyphase systems employing single core cablesthe sheaths of which are separated into insulated lengths, the breaks are bridged by reactance coils with secondary windings and the :secondary windings are connected in series in a closed circuit. The mid points of the reactances may be connected together and earthed or connected to other cable sheaths. Sheath voltages are minimized and the secondary winding results in very low impedance to fault currents, prevents strong magnetic flux reaching the iron case and eliminates triple harmonic currents in the sheath circuit. In a three-phase transmission a threelimbed core 4a is preferably used, with a re- .actance 6 on each leg and secondary coils 8, one on each leg. The secondary windings may be replaced by one or more conducting rings 10, Fig. 5, embracing all three cores. In a modification the sheaths are cross-bonded at the joints and the reactances 6<a> connected between the sheaths and a common point, preferably earthed, as in Fig. 5. Specification 298,237 is referred to. According to the Specification as open to inspection under Sect. 91 (3) (a) resistances or impedances may replace the coils 6a, and the invention was stated to be applicable to single-phase systems. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for the continuous monitoring of liquid phase solutions
Inventor: AARTS WILLIAM HENDRIK
IPC: G01N21/85
Filed: 1958-09-22
Abstract: 899,907. Measuring specific gravity. AFRICAN EXPLOSIVES & CHEMICAL INDUSTRIES Ltd. Sept. 21, 1959 [Sept. 22, 1958], No. 30171/58. Class 97(3). [Also in Group XL(b)] The concentration of a component in a liquid phase solution is measured continuously by passing the liquid at a constant velocity through an elliptically shaped orifice 29 so as to produce a jet 4 exhibiting a system of standing waves, and the position of a wave maximum is detected photo - electrically by illuminating the jet with light 5 and using the refractive and/or reflective effect of the shaped liquid to focus a light spot on a photo-cell system 6. The wave length is dependent on the t ratio -, where t equals surface tension and d d equals density, so that where changes in the concentration result in a change in this ratio, such changes may be determined by detecting the change in position of a wave. The photocell system 6 which together with a source of illumination is mounted on a carriage so as to be movable in the direction of the liquid jet, comprises a pair of closely spaced prisms 10, 11 by which light may be directed on to photo-electric cells 7 and 8. The light beam is normally focused between the prisms and any movement of the beam consequent upon a change of concentration causes one or the other photo-electric cell to be illuminated, An electric motor 14 is then energized to turn a screw 16 to move the carriage until the light beam is again centred between the prisms. A drum potentiometer 17 is also rotated with screw 16 and is connected in a bridge circuit, Fig. 5 (not shown), having a galvanometer which may be calibrated in terms of concentration. The liquid issues through orifice 29 from constant head tank. A platinum resistant thermometer 2 mounted in the tank is connected in the bridge circuit to furnish temperature compensation. In Fig. 1 the light beam is directed through the liquid jet. In a modification, Figs. 2 and 3 (not shown), the beam is projected on to the beam from the same side and in the same plane as the photocell system, a focused image being formed by a combination of refraction at the front surface and reflection from the rear surface. In an arrangement for use where the liquid gives off noxious fumes, Fig. 4 (not shown), the photo-cell system is located behind a window which is swept continuously by a film of the liquid under measurement so as to prevent the condensation of drops of the noxious fumes.
