Title: Improvements relating to signalling systems employing light emitting devices
IPC: H05B39/09
Filed: 1921-11-09
Abstract: 176,313. McKenzie, Holland, & Westinghouse Power Signal Co., (Assignees of Howard, L. F.). March 2, 1921, [Convention date]. Lamp-failure alarm and warning devices.-A cell responsive to the light emitted from a lamp controls an indicator. As applied to railway signalling, the cell F of selenium, stibnite, or other material, is influenced by the rays of the donger signal R so that the current flowing in the circuit containing the cell F, magnet 16, and transformer secondary winding 3 is varied, moving an armature 21 so as to raise a dog 14 clear of the shoulder 15 on the operating-lever A. The lever can then be moved to the end of its stroke. Contacts on the armature 21 complete the circuit of indicating-lamps R', G'. In a modification the cell F is in series with a relav which completes the circuit of indicating-lamps R', G', and magnet 16. The cell may be used in one arm of a Wheatstone-bridge arrangement which is balanced so that normally no current flows through the magnet 16 or the relay, or the cell may be used in a circuit containing an indicator and a potentiometer and two secondary windings of a transformer in which the currents are adjusted by the potentiometer to neutralize each other so that normally none flows through the indicator and cell.

Abstract: 462,759. Hydraulic transmission of power. CLENCH, E. C. S., and AUTOMOTIVE PRODUCTS CO., Ltd. Nov. 2, 1935, No. 30333. [Class 69 (ii)] In a remote fluid-pressure control system, the controlled element of the system can be remotely disconnected from the actuating- means from a position adjacent the transmitter device in the case of the system failing. The slave cylinder A is connected by pipe lines 11, 12 to the master cylinder B. The handle 13 effects the movement of the double-acting piston 14 which moves the link 16 connected by a removable pin to the actuated arm 18 of the control throttle. This is urged by a spring 20 to its open position. The piston 14 is locked in its end positions by apparatus of the kind described in Specification 443,871 which is released when pressure enters one of the pipes 11, 12. In the event of the system becoming inoperative, the pin is disconnected from the control end by a ring 29 connected through a cable housed in a flexible tube to a tension cable 25. A chain or push rod may be used instead of a cable. The disconnecting-means may, in some cases, serve in a limited sense to actuate the disconnected element through, for example, a bell-crank one arm of which is engaged by the disconnected lever 18 and the other arm by the withdrawn pin secured to the cable which passes through a hole in the arm.

An inductor coupling between drive lines 11 and sense lines 12 is achieved by a pattern of coupling conductors 14 which may be, as shown, printed on an insulating sheet or formed by punching out the complementary pattern on a copper sheet. The patterns for binary one and zero are such that, whatever the value of the bit stored, a constant impedance is presented to the drive and sense currents. Several variations of the patterns shown at 14, 15 are described in the Specification. In providing for a ternary code a further pattern is used which gives rise to no e.m.f. in the sense line. The looped ends of the drive and sense conductors may be terminated by their characteristic impedance to prevent reflection of high frequency currents. Specification 996,172 is referred to.

IPC: B64C35/00
Filed: 1923-12-07
Abstract: 224,486. Schneider et Cie. Nov. 5, 1923, [Convention date]. Floats and hydro-aeroplanes. - The landing- wheel supports of hydroplanes are constituted by floats or sustaining surfaces, or portions of floats or sustaining surfaces, which are pivoted in such a manner that for landing or taking off the ground they may be positioned to bring the wheels into use, but for hydroplaning they may be raised to form floats or sustaining surfaces, or additions to the main floats or sustaining surfaces. Fig. 1 shows a seaplane, the wheel supports a of which are constituted by portions of the side floats c and are pivoted on axles d. In the position for travelling on the water or in the air, the wheel-carrying float portions a complete the contour of the side floats, the projecting parts of the wheels being housed in recesses which may be closed by shutters A. To lower the wheels, a cable s, Fig. 4, attached to a sliding sleeve m, is unwound from a drum, thereby allowing the wheel-float a (if necessary assisted by a spiral spring coiled about the axle d) to drop into a vertical position, and extend two jointed levers e, f, the outer ends of which are pivoted respectively to the float a and the hull C. When the levers e, f are fully extended, the sleeve m is urged by a spring r over the joint g, where it is arrested in a locking position against a stop E. To raise the wheel-float, the cable s is wound on the drum t and the sleeve m slides along the lever f to unlock the joint g. When the sleeve m reaches the limit of its sliding movement, the levers e, f are folded about the joint g and the float a is brought into its raised position. A cable w may be actuated simultaneously with the cable s to raise or lower a tail skid. According to modified forms of operating mechanism, the floats a are rotated about. the axles d through worm gearing, or by means of a system of bellcrank levers. The wheel-carry floats a may also be enclosed on their front and rear sides bv portions of the main floats c, or they may form independent floats and be quite separate from the fixed floats or hull. According to another modification, the wheel-float a, Fig. 8, may be pivoted on an axle d on the hull C.
