Abstract: 647,930. Electric control systems. FAIRBAIRN, P. R., and MACLAREN, H. D. Sept. 29, 1948, No. 25437. [Class 40 (i)] In an electromagnetic pick-up device, e.g. for operating a gyroscopic stabilizer, a steel pot electromagnet a, Figs. 1, 3, has a central spigot a<SP>1</SP> surrounded by a coil energized by A.C. of frequency, e.g., greater than 200 c.p.s., and is movable two-dimensionally by an arm b, carried by a controlling gyroscope, relatively to an E-shaped magnetic yoke whose centre arm is divided into four equal sections e<SP>1</SP>, e<SP>2</SP>, e<SP>3</SP>, e<SP>4</SP> by mutually perpendicular slots, within which are wound two pairs of search coils xl, x<SP>2</SP>, yl, y<SP>2</SP> so that the coils of each pair overlap in one slot and intersect the overlapping parts of the other pair in the other slot. The coils of each pair are oppositely connected so that the induced voltages therein normally balance out when the yoke and electromagnet are mutually symmetrical and displacement of the armature from symmetry relative to the yoke develops A.C. signals in the pairs of coils which are proportional to the co-ordinates of the displacement, and may be amplified to operate servomotors (not shown) maintaining the yoke and' armature in symmetrical alignment. The energizing winding may be located at the root of the centre limb of the yoke.

Title: Transistor regulator circuits
IPC: G05F1/573
Filed: 1958-08-11
Abstract: 878,990. Automatic voltage control systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1958 [Aug. 13, 1957], No. 25675/58. Class 38 (4). In a direct-current regulator circuit, the base current of a transistor connected between a source and a load is controlled by an error detection circuit, and a control arrangement is responsive to an over-current through an impedance to limit the dissipation of the transistor. As shown, a direct-current supply is derived through a constant-voltage ferroresonant transformer 10. a rectifier 12 and smoothing filter 13, and the voltage across a load 16 is maintained constant by a series regulator 15 comprising a transistor TR1. Variation in the load voltage unbalance a bridge comprising Zener diodes Z 1 , Z 2  and resistors P, R, R1, R2. The out-of-balance voltage of the bridge is sensed by an error detector 17, comprising transistors TR2, TR3, and through a cascade transistor amplifier TR4, TR5 controls the base current of the transistor TR1. Over-current flowing through a resistor R s  applies a bias to the base of the transistor TR1 through a resistor Ra so as to limit the dissipation of the transistor. The collectors of transistors TR2, TR3 are maintained at substantially equal voltages by the currents through resistors R3, R4 so as to compensate for temperature effects. The bridge is adjusted by the potentiometer P.

Abstract: 1,029,618. Forced flow steam boilers. FOSTER WHEELER Ltd. June 15, 1964 [June 27, 1963], No. 25710/63. Heading F4A. A once-through steam boiler heated, for example, by the gas coolant of a nuclear reactor comprises a cylindrical shell 10 housing an axially disposed bundle 22 of vertical superheater tubes 44 and a number of identically arranged bundles 20 of vertical evaporating tubes 28 arranged around the superheater. Feedwater enters the bundles 20 through respective pipes 34, headers 32 and helical expansion distributers 24, wet steam passing from collector headers 36 through pipes 38, 50, 48 and header 46 to the superheater bundles whence superheated steam leaves the boiler through a pipe 54. The heating gas enters through a duet 12 which widens to form a baffle 18 which is overlapped by a baffle 16. The baffles divide the gas stream into two parts one flowing upwardly over the superheater and downwardly over the baffle 16 in contact with the shell wall whilst the other passes upwardly through the annular space 53 between the baffles and downwardly over the evaporating tubes, the two streams combining for flow through a discharge duct 14. Thus the heating gas flows in countercurrent to the working medium flow. Furthermore, the shell is only contacted by gas which has been cooled in contact with heat-exchange surfaces.
