[Class 38 (iv)] [Also in Group XXXVII] Switching control.-An arrangement to prevent continued flashing of a faulty discharge lamp 10 having a thermal switch S that closes a starting circuit H through which current passes to heat the filaments 11, and then opens the circuit to apply the full voltage to the lamp, comprises a heater in series with the switch and cumulatively responsive to repeated current flow to render the switch inoperative by maintaining it in its closed position. A glowdischarge switch S comprises a bimetallic strip 26 that bends when heated by the discharge between it and a fixed contact 25 causing a contact piece 27 of molybdenum on the strip 26 to engage the contact 25, which is of nickel. The increased current heats the filaments and the strip 26 cools and separates the contacts 27, 25 again to start the discharge. Connected in series with the switch is a heater 30 having a large thermal capacity arranged in proximity to the strip 26. This heater does not interfere with normal operation of the switch S, but after repeated unsuccessful operation its temperature rises sufficiently to prevent the strip 26 cooling and breaking contact with the member 25. Specifications 560,075 and 560,707 are referred to. The Specification as open to inspection under Sect. 91 comprises also a proposal to lock the starter switch in its open position and a reference to Specification 542,853.

Abstract: 244,303. Sweeney, O. R. March 7, 1925. Purifying liquids; filters with loose materials; filtering-media.-Water to be softened is delivered to base-exchange material 2 in a very fine state of division by passing it through a structure having very fine pores, such as metal cloth 11 or a slab 36. Channelling of the material 2 is thus prevented. The metal cloth has about 5000 interstices to the square inch, and may be flattened after wearing to reduce the size of the openings. The slab 36 may be made from sand fused into a porous mass, or rotten-stone, pumice, or sintered aluminium oxide may be used. Quartz &c. 14, perforated corrugated plates, or a metal grating support the metal cloth, which also serves to filter the unsoftened water. The dished end 9 of the container 4 serves as a settling-chamber. Channelling of downwardly-flowing regenerative solution introduced through the funnel 23 may be prevented by a slab 36 or metal cloth placed at the opposite end of the base-exchange material. Washing after regeneration is effected in the usual manner. The plant may operate by downward flow.

Title: Improvements in or relating to amplifier circuits for use in image-transmission
IPC: H04N5/16
Filed: 1948-03-03
Abstract: 663,857. Copying-telegraphy; television. PHILIPS ELECTRICAL, Ltd. March 3, 1948 [March 6, 1947], No. 6699/48. Class 40 (iii). In an arrangement for eliminating distortion in an amplifying circuit in which the coupling between a first amplifying valve and a second amplifying valve includes a shunt rectifier and a series condenser, the anode and cathode of the rectifier are connected through condensers to the anode and cathode respectively of said first amplifying valve, the anode and cathode leads of the first valve include impedances of the same kind, and the rectifier is shunted by a tapped resistance, two points of which are connected respectively to the control electrode of said second valve and to a point of fixed potential. The circuit arrangement which is shown in Fig. 7 and is of particular advantage for facsimile telegraphy is a modification of a known arrangement, shown in Fig. 6, comprising first and second amplifying valves 1, 4, a coupling condenser 3 and the shunt diode 8. If the output impedance 2 of the valve 1 is relatively high, as in the case of the use of the circuit in copying-telegraphy, the flow of diode current through the condenser 3 and anode resistance 2 reduces the anode voltage of the valve 1 so that the synchronizing pulses which are also used to stabilize the black level are deleteriously reduced. In the modified circuit shown in Fig. 7 the left-hand plates of the condensers 10, 11 are connected to the anode and cathode of the valve 1 and the right-hand plates are effectively connected together when the diode 8 conducts so that the resistances 2, 6 and condensers 10, 11 form a bridge with the valve 1 as its diagonal. If the bridge is balanced by making the values of the resistances 2, 6 inversely proportional to the capacities of the condensers 10, 11 the fall in the anode voltage of the valve 1 does not affect the voltage on the grid of the valve 4 whilst the diode 8 functions as a short-circuit. The resistances 12, 13 having the tap 14 operate as a single resistance when the diode 8 is conductive. When the diode ceases to conduct current flows through the resistances 12, 13 to alter the charges on the condensers 10, 11 and the values of the resistances 12, 13 are arranged to be inversely proportional to the capacities of the condensers 10, 11. To reverse the nature of the reproduced print, e.g. a negative instead of a positive, the grid of the valve 4 may be connected to the lower end of the resistance 13 in lieu of the connection, as shown, to the upper end of the resistance 12.

Abstract: 105,275. Peters & Co., G. D., and Hibberd, F. C. May 10, 1916. Pipes and tubes.-Return bends or connectors for steam-superheater elements are formed from solid pieces of iron, steel, &c. by dies which first bring the metal to the shape shown in plan and side view in Figs. 2 and 3 respectively. A further pair of dies force the sides J, K of the hollow forging towards one another, two cylindrical mandrels G being placed, as shown in Fig. 6, to form circular tube-receiving openings. The forging is finally cut away at these openings to a certain depth, leaving a solid middle portion H<1>, Fig. 8, which takes between the connected tubes. A modified mode of producing the bend consists in employing dies N, 0, Fig. 11, which form halves, each as shown in Fig. 13, which are welded together, and to the tubes L, L<1>. A further form of connector is shown at S, Fig. 16, being used to join two pipes P, P<1> tc a tube P<2>. Dies as in the first-mentioned process are employed, and the bottom of the forging is cut off for the introduction of the tube P<2>.

Pipes 47, 48 connect the air pick-off to the chambers on opposite sides of a diaphragm 50 actuating a balanced valve 52 controlling a hydraulic cylinder is also connected by pipes 24, 25 to a second balanced valve 21 actuated by the gimbal 9 of the oil-spun gyroscope 8. This gimbal is adjustably loaded by a spring 43 arranged between a pin 44 on an arm 45 on the spindle 10 of the gimbal and a pin on an arm 42 carried by a shaft 36. The shaft 36 is turned to adjust the spring by a knob 31 with a pointer moving over a scale 68 acting through a flexible cable 32 and worm gearing 34. The arm 42 is held in its adjusted position by a spring catch engaging depressions in a sector 39 secured to the arm 42. The air-spun gyroscope is put out of operation during a controlled rate-of-turn by closing a valve 60 in a conduit connecting the valve 52 with the oil sump. A compass card 66 is turned by the knob 58 and a lower card 67 is carried by the gimbal frame 9.
