Abstract: 556,127. Pressure gauges. BENDIX AVIATION CORPORATION. March 17, 1942, No. 3349. Convention date, March 15, 1941. [Classes 106 (ii) and 106 (iv)] Mechanism is provided between the pressuresensitive element and the indicating pointer so that the latter is moved over the scale at a relatively greater ratio of movement during small pressure differentials, the ratio decreasing as the pressure differential increases. In the rate of climb indicator, Fig. 1, the diaphragm 16 is mounted within a sealed casing 10 which is in restricted communication with the outer atmosphere through a member 19 which may be; a diffuser of type described in Specification 507,991. The inside of the capsule or diaphragm 16 is in unrestricted communication with the outside atmosphere via a pipe 18 passing through the member 19. The diaphragm 16 is carried by a flexible member 22 which may be adjusted by a coned screw 23. Movement of the diaphragm 16 is transmitted by a link 29 to an arm 27 on a rock shaft 26 and hence by finger 33 and sector 35 and pinion 36 to a gear 36 on shaft 37. A driver arm 38 secured to shaft 37 carries a pin 39 projecting into an elongated slot 40 in an arm 41 on an axis 42 which is eccentric with respect to the axis of shaft 37. The shaft 42 carries a pointer 44 In moving either way from the zero position shown; the pointer moves to a greater extent in the smaller ranges than in the higher for the same movements of the diaphragm owing to the linkage 38, 40. In a modification the pin 39 engages a slot in the pointer itself.

Title: Improvements in and relating to hydraulic control systems
IPC: G05D1/08
Filed: 1940-02-27
Abstract: 538,526. Controlling aircraft. SPERRY GYROSCOPE CO., Inc. Feb. 27, 1940, No. 3649. Convention date, March 1, 1939. [Class 4] [Also in Group XXIX] A hydraulic control system, which is especially applicable to an automatic pilot system in which the position of rudder 30 is controlled by differential air pick-off devices operated by gyroscopes as described in Specification 515,290, [Group XXIX], is constructed with a controlling valve device 10 with an operating lever 3 which may be operated manually, or automatically by pneumatic members 2, 2' connected by tubes 1, 1<1> with the pick-off devices, or by electromagnetic means or by a torque motor. The valve 10 operates in connection with a double gear pump 17 operated by a single motor 23, a portion of the fluid normally passing from a pump 19 via pipe 31, gear pump 23, 24, pipe 18, valve channel 15, valve 13, and pipe 21 back to the sump. Another portion of the fluid passes to the pump 22, 24<1>, and returns via pipe 18', valve channel 15' and valve 13<1> back to the sump 19. At the top of each channel 15, 15' a pipe 26, 26<1> leads to a cylinder 27 in which is a piston 28 which controls the position of the rudder 30, and which is normally acted upon by equal pressures on each side so as to exert no turning movement. The lever handle 3 operates a lever with knife edges which control the positions of piston rods 14, 14<1>, attached to pistons 13, 13<1> which act as valves, one piston being caused to rise to check the flow of fluid in the valve channel 15 (say) while the other drops to lower the pressure in the other channel 15<1>. The pressures on opposite sides of the piston 28 are thus also affected, and the piston moves towards the side of low pressure and rotates the rudder 30 until the air pressure on the rudder balances the operating pressure. This adjustment takes place without delay' due to a " hunting " action. The pressure on the faces of the pistons 13, 13<1> is normally substantially balanced by a pressure on the reverse side of fluid which is admitted by byepass to passages 44, 44<1>. The position of the inlet opening of these passages is set so as to provide for the difference in pressure of the fluid passing through the valve due to the decreased hydrostatic pressure caused by increased velocity flow which under normal conditions would cause the pressure on the centres of the pistons 13, 13<1> to be greater than at the periphery.

[Class 83 (iv)] [See also Group II] In a method of tempering rails, the rails R, upon leaving the rolling-mill, and whilst resting on their flanges, are heated to the exact temperature required below a roof 1 heated by electrical resistances 3. The heated rails, upon leaving the roof, are seized by claws 8, 9 connected together by links 10 and by links 12, 13 to a shaft 11 mounted on arms 6 carried by a shaft 4 supported on a frame 5. While the rail is locked within the claws 8, 9, any oxide thereon are removed by a brush 15, Fig. 3, supported by rollers 16 on anvil 17, the brush being moved along the rail 17 to contact with the surface of the rail R. The shaft 4 is now operated in the direction of the arrow F to bring the head of the rail into a tempering bath. The arms 6, may be raised and lowered to immerse the rail in the bath a number of times. To release the rail, after the completion of the tempering, the apparatus is raised to permit the conveying carriages 22 of the cooler 2 to be placed below the rail and the latter is released from the claws 8, 9 by the operation of a piston 24 in a cylinder 23. The rail is now seized by the hooks 25 and placed on the carriages 22. When the rail has been released the shaft 4 is turned to bring the apparatus back to the position shown in Fig. 1.

[Class 38 (iv)] In a method of initiating electric arcs, more particularly for treating hydrocarbons, in which a number of arcs are connected through controlled rectifiers to the same supply, the arcs which are burning are temporarily operated, during the ignition of a further arc, with a power factor which is adjusted by suitable control of the rectifier, or of the gas charge to the arc, so that the limiting power factor for stable operation is not exceeded. For example, the voltage of the supply, or to each rectifier, may be temporarily increased. The voltage on the control grids of the rectifiers may be varied in phase or magnitude to increase the current to, and thus reduce the power factor of, the arcs already burning,

Title: Improvements in or relating to apparatus for measuring electric resistances, particularly insulation resistances
IPC: G01R27/02
Filed: 1938-02-08
Abstract: 510,801. Resistance measurements. STANDARD TELEPHONES & CABLES, Ltd., LEMAN, H. S., and JORDAN, E. W. Feb. 8, 1938, No. 3927. [Class 37] In a resistance testing apparatus wherein a resistance under test is connected in the grid circuit of an electron discharge tube so that the grid potential varies in accordance with the resistance value, a relay connected in the anode circuit is arranged to effect operation of a visual or audible signal if the resistance value is below a predetermined amount. As shown, an indirectly heated H.F. pentode valve 7 is used, the potentials of the various electrodes being supplied from a potentiometer R1 ... R7 connected across a D.C. source X X. ' Included in the anode circuit is a relay 12, biassed by an adjustable spring, or adjustable by a rheostat R22, so that on a predetermined fall of anode current the relay contacts close and energise a further relay 19 which locks up and operates a visible or audible signal 24 continuously until a reset key RK or an extension reset key 26 is operated. The resistance to be tested is connected, for example, by test prods, across terminals 13, 14. Terminal 13 is connected through a contact arm 15 to one of the contacts, P1 ... P6, corresponding to the rated value of the resistance under test, causing a current to flow from a D.C. source Y through a part of a resistance bank R14 ... R9, the selected contact PI ... P6, terminal 13, the resistance under test, and back through terminal 14 to the source Y. The consequent potential drop across the operative portion of the resistance bank R14 ... R9, reduces the grid potential, normally supplied by the potential drop across the resistance R4, and therefore reduces the anode current. The resistance bank R9 ... R14, the tapping contacts P1 ... P6, and supply Y are so arranged that with the appropriate tapping P1 ... , in use, the fall in anode current is insufficient to release the contacts of relay 12 if the resistance under test is satisfactory, but if its value is below the rated value, the relay 12 is released and the signal 24 actuated to indicate that the resistance is faulty. Resistances R8, R15 ... R20, and R21 are protective resistances, and a resistance R25 and condenser C5 are connected across terminals 13, 14, to prevent the capacity of a resistance under test affecting the grid potential. The apparatus may be tested for the setting of relay 12 by a key 25. If raised, the key alters the grid potential to the potential drop across R4 + R5. This corresponds to a satisfactory resistance under test and the relay 12 should not release. Then, by depressing the key 25, the grid potential is increased negatively to the potential drop across R4 + R5 + R6. This corresponds to a faulty resistance and should release the relay 12. Modifications.-The supplies X-X, Y-Y, for the valve filament and for the indicator 24, instead of being obtained, as shown, from A.C. mains, could be obtained from batteries or a universal, i.e. A.C.-D.C. mains unit.
