Patent GB-188025-A (GB)
Title: Improvements in or relating to burners for fluid-fuel
IPC: F23D11/10
Filed: 1921-07-01
Abstract: 188,025. Bliss, J. July 1, 1921. Air and steam pressure sprayers.-The fuelsupply tube 10 of a liquid-fuel burner is secured at one end in a bored plug 11 which closes one end of a jacket 12 to which steam, hot air, or other atomizing-fluid or gas is supplied through an inlet 24. A nozzle 14 secured to the outlet end of the fuel tube has a cylindrical exterior middle portion 17 and a tapered extremity 18 fitting in a burner nozzle 19 which is tapered inwardly to a restriction 23 and then flared outwardly. The fuel passes through a restriction 16 in the nozzle 14 and issues into the nozzle 19 through an outwardly flared bore on which it is met and partially atomized by steam from the jacket space delivered through converging conduits 31. The atomization of the mixture is completed in the nozzle 19 by swirling streams of the steam delivered through inclined passages 21 in the cylindrical portion 17 of the nozzle 14 and the tapered annular space 22 between the nozzles 14, 19. The passages 21, 22 may alternatively be formed in the burner nozzle 19 or be partly in the fuel nozzle 14 and partly in the burner nozzle 19.

Title: Improvements in Mountings for the Support of Instruments on Board Ship.
IPC: F16M11/22
Filed: 1918-11-04
Abstract: 134,339. Barr & Stroud, Barr, A., and Stroud, W. Nov. 4, 1918. Vibration, preventing, in ships. Relates to the construction of an anti-vibration mounting for searchlights, range-finders, &c. on board ship in which springs are employed having a long free period as compared with that of the deck &c. The instrument 20 and observers are carried on a sleeve member 2, which is guided from, and has a slight vertical movement relative to, the pedestal 1. The whole weight is taken by the nut 7 secured to the helical spring 4, which is not thereby fully stressed and is carried by the pedestal. Two interwound springs in tension may be employed. Rollers 9, 10 and ball bearings are introduced where necessary to facilitate either vertical or rotational movement. Links, such as 14, 15, 16, are provided when a heavy instrument has to be controlled in azimuth and is yet to be free to move vertically with the sleeve. When supporting a light instrument such as a dial, not moving in azimuth, there may be a slot and feather connexion between the instrument carrier and pedestal.

Title: Improvements relating to gas reforming plants
Inventor: HEMMINGWAY CHARLES WILFRED
IPC: C10K3/04
Filed: 1963-05-07
Abstract: <PICT:1011138/C4-C5/1> In the production of fuel gas by the reforming of hydrocarbons the temperature of the reformed gas supplied to the shift converter is regulated by passing a controlled portion of the gas through a waste heat boiler to cool and returning this portion to the remaining gas before introduction into the shift converter. The temperature of the gas may thus be reduced from between 800 DEG  and 850 DEG  C. to between 350 DEG  and 400 DEG  C.  Figures 2 and 3 illustrate alternative forms of apparatus.  Reformer 1 releases hot gas both through outlet 6 to waste heat boiler 7 to cool, and through pipe 8 to shift converter 9, the relative amount being controlled by butterfly valve 21.  In Figure 2 the effluent gas from the shift converter passes through upper section 12 of the waste heat boiler and in Figure 3 through steam superheater 23, and thence in both figures to scrubber 14 and out of the plant.

Patent GB-613567-A (GB)
Title: Improvements in or relating to stabilized thermionic valve oscillators
IPC: H03K5/00
Filed: 1946-06-17
Abstract: 613,567. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., JACOBSEN, B. B., and FRANKTON, W. J. June 17, 1946, No. 18116. [Class 40 (vi)] In a thermionic valve oscillator having a feedback loop between the anode and control grid circuits, the frequency determining circuit is in the feedback loop, but external to a bridge circuit also in the loop which stabilizes the amplitude of the generated oscillations. The bridge comprises in two arms a fixed resistor and a temperature dependent resistor, the other two arms being comprised by a centretapped inductor. In this way the power losses in the bridge circuit are substantially reduced. The Figure shows a valve 1 having a positive feedback circuit inductively coupled between its anode and control grid. The centre-tapped winding 20 with resistor 21 and temperature dependent resistor 22 form a bridge circuit of known type, which renders the output of the oscillator of substantially constant amplitude. Resistor 22 may be, for example, a carbon filament lamp or a directly heated thermistor. The frequency of oscillation is mainly determined by the resonant frequency of winding 12 and capacitor 15. The winding 2 is preferably tuned to the oscillation frequency by capacitor 25 and the output is taken from across terminals 18, 19. The amount of negative feedback is adjusted by the variable resistor 11. The neutralizing capacitor 26 enables a greater oscillator stability to be maintained with variations of load impedance across the output terminals. In a modification, Fig. 2 (not shown), the cathode of the valve is connected to earth via a potentiometer, the variable contact of which is decoupled to earth, the control grid being connected to the junction point of two resistors connected across the H.T. supply. Specification 510,379 is referred to.

Abstract: 516,176. Converting. METRAWATT AKT.- GES. FABRIK ELEKTRISCHER MESSGERAETE. June 22, 1938, No. 18563. Convention date, June 23, 1937. [Class 38 (ii)] [Also in Group XXXVI] In a measuring instrument, particularly for testing insulation, comprising a D.C. voltage source (of e.g. about 100 volts) in series with a measuring instrument P and a pair of test terminals RX, the test voltage is derived from a low tension battery B connected across the commutator brushes K of a D.C. permanentmagnet motor M. The alternating current in the armature winding flows through the primary of a step-up transformer TR series-connected with the armature by means of slip rings R', R<2>, and the transformer output is led by slip rings R<3>, R', to a commutator K<2>, the high tension D.C. output from which is connected through smoothing arrangements, if desired, and a moving coil instrument P to test terminals RX. The voltage output at RX may be. controlled by a variable resistance V<1> in series or parallel with the transformer primary, and in addition by a resistance connected as voltage divider across the transformer secondary. For earth connection tests of live A.C. power supply lines, the alternating voltage output from terminals EE is used with switch S' open and the primary winding of the transformer TR preferably interrupted or short-circuited by a contact coupled to the switch S<2>. The motor M is such that the frequency of the output at EE differs from that of the supply line under test. The apparatus may be used as a line tester by connecting the battery B over switches S', S<4> in series with a variable resistance V<2> the meter P and test terminals RX. According to the Specification as open to inspection under Sect. 91, the primary of transformer TR may be in parallel with the motor armature winding and a series resistance provided between the commutator K<2>and meter P. This subject-matter does not appear in the Specification as accepted.
