Title: An ac source switching system
IPC: H03K17/72
Filed: 1968-04-24
Abstract: 1,205,707. Standby supply systems. BORGWARNEB CORP. 24 April, 1968 [1O May, 1967], No. 19470/68. Heading H2H. A standby power supply system comprises means whereby the normally used source is connected to a load through a first switching means and, upon failure of the normal source, the first switching means disconnects the load from the normal source, the load then being connected to a standby source by a second switching means. A load 11 is connected to a normally used source 12 by means of a normal source switch 14, the normal source being continuously monitored by means of a sensor 16. The sensed signal is compared with a reference signal derived by a circuit 18 so as to provide an error signal 19 at any time during which the amplitude of the voltage of the source 12 is outside a predetermined range. When an error signal 19 exists it causes a logic circuit 20 to be operated so as to put the normal switch 14 into its "open" condition and the standby source switch 15 into its "closed" condition, whereby the load 11 is then supplied by the standby source 13. The switches 14, 15 are in the form of diode bridges across the output terminals of which are controlled rectifiers controllable by way of the logic circuit 20, indicating lamps being provided to indicate which source is supplying the load. The logic circuit comprises a pair of output transformers each controlled by way of a unijunction transistor, the output transformers providing the signals to operate the controlled rectifiers of the switches 14, 15. The sine wave reference circuit 18 is arranged so as to produce a reference signal that is "locked-in" and "in-phase" with the source 12 thus ensuring that the system can respond instantaneously to variations in the magnitude of the voltage of the source 12. The reference circuit 18 essentially comprises a pair of transistors arranged to function as a bi-stable switching means.

Title: Electrical measuring instrument
IPC: G01R5/18
Filed: 1975-05-09
Abstract: 1477978 Moving-iron instruments WESTINGHOUSE ELECTRIC CORP 9 May 1975 [20 May 19741 19659/75 Heading G1U A moving-iron instrument includes a coil assembly 20 with two flat magnetic plates 28, 30 and a coil 34 defining an opening in which a magnetic element 64 extending between the plates rotates due to the interaction of the element with the flux generated by the coil 34 which causes a torque owing to attraction between the element 64 and the plates, wherein at least one plate has an opening bounded by a spiral shape (e.g. 40) such that the permeance of the magnetic circuit between the plates formed in part by the element varies this rotates. As shown, both plates have spiral shaped openings 40, 42 and they are linked by U-shaped members 16, 18, completing the magnetic circuit. The element 64 in its rest position lies in the area having the greatest radius (i.e. near the slot 27 provided for inserting the movement 58). Thus as the current increases and the vane rotates, the permeance of the magnetic circuit increases as the radius of the opening decreases. This allows for a linear current/deflection response over a large portion of the scale. To increase the overall angular length of the scale, the difference in permeance between the rest and fullscale deflection positions must be large. To increase this difference the magnetic potential at the zero position is decreased by a shield member 68 extending in a path between the plates 12, 14 and adjustably mounted on the support plate 22 of the movement 58 by a slotted bracket 70 and screw 71. To further increase the difference in permeance, the magnetic potential at the full-scale deflection region is increased by providing projections 50, 52 in the openings. The movable element 64 is shielded from the projections 50, 52 when at the zero position by an extension 80 on the shield member 67. The magnetic parts of the instrument are made from iron-nickel alloy, and the suspension may be tautband or jewelled bearings with a spiral spring providing the restoring force.

[Class 40 (i)] In an automatically-balanced, power-operated weigh-beam, deflection of the beam from the neutral position closes contacts to energize direction and speed relays in the control circuit of a shunt motor driving the jockey-weight. The motor field is continuously energized and the armature is short-circuited by the direction relays at balance to provide magnetic braking. Additionally, the beam contacts may control an electromagnetic damping device such as that described in Specification 651,224, [Group XXXII], to prevent oscillation of the beam when the weight is suddenly stopped. Operation.-Assuming the beam is unbalanced to close the upper contacts 2, 5, and 3, 6, speed relay 15 is energized to short-circuit resistance 43, and direction relay 20 is energized to make a circuit for the motor armature 28 over contacts 26, and 27 to the D.C. supply 10, 11. As balance is approached coarse contacts 2, 5, open and the speed relay drops out to insert resistance 43 in the armature circuit.

Title: Improvements in or relating to the formation of electrophoretically deposited metal coatings
Inventor: JACKSON ALBERT EDWARD
IPC: C25D13/16
Filed: 1963-02-14
Abstract: In forming metal coatings on metal strip by electrophoretically depositing the coating metal from a suspension of finely divided coating metal, drying the coated strip to remove entrained electrophoresis medium, rolling the coated strip to compact the coating, and then heating the strip to obtain a tightly bonded coating, the strip is passed in a straight pass to a roll having a surface to which the coating is non-adherent, e.g. chromium- or nickel-plated steel, polythene or P.T.F.E., the strip being dried in said straight pass to a liquid content of 20-75% by weight of the coating, at which stage the coating is sufficiently coherent to be contacted by the roll to cause change of direction of the strip so that it passes to the drying station and compacting rolls. The reduction of liquid content of the coating is effected by means of air knives across the strip width impinging at an acute angle, e.g. 30 degrees, to reduce drag-out loss, together with radiant heaters, and final drying is effected with hot air or gas or by radiant heating.  The electrophoresis bath is the same as that in Specification 979,948 and the suspension is maintained and solvent is recovered as in that Specification. The consolidating heat treatment of the compacted coating is effected on the coiled strip. Specification 884,797 also is referred to.
