Title: Improvements in telegraphy
IPC: H03M7/40
Filed: 1931-11-14
Abstract: 391,518. Code telegraphy. WESTERN UNION TELEGRAPH CO., 195, Broadway. New York, U.S.A. Nov. 14,1931, No. 31603. Convention date, Aug. 27. [Class 40 (iii).] One channel of a multiple distributer system is allotted to a cable-code transmitter which is driven independently of the distributer and is not synchronized. One five-segment channel of the sending-ring R2 is allotted to the cablecode transmitter XTR, which may be of the type described in Specifications 275,538 and 318,841. Each dot, dash or space occupies sometimes two and sometimes three segments, the proportion of two-segment elements increasing if the speed of the cable-code transmitter XTR increases relatively to that of the distributer. The segments 1 .. 5 allotted to this transmitter are fed by storing relays SPR and these are set by impulses from a ring R1, the brush bl wiping over the conducting segments 2 .. 5, 1 (shown as white) of the cable-code channel, while brush b2 serves all the channels. A full-length dot is represented by + + +, Fig. 3, a full-length dash by - - - , and full-length space by + - + or - + - as the case may be. Conversion of a no-current perforation into the required space signal is effected by means of the auxiliary winding 10 of relay SCR, which is connected to a condenser 16 and resistance 15, so arranged that condenser 16 discharges through winding 10 when brush b1. quits a conducting segment of ring R1. Hence, when control winding 11 is disconnected by the transmitter XTR, winding @0 acts to reverse the armature 14. A reversed impulse is therefore sent through the next segment of ring R1, and by repetition of this action a + - + or - + - signal is sent on. At the receiver the cable-code signals are conveyed though segments 1 .. 5 of ring R3 to storing relays RDR and thence via segments 2 .. 5, 1 of ring R4 to relays RCR1 and RCR2, and via segments x of ring R4 to a relay RCR3, the latter relay having a delay-circuit 39, which delays its action by an interval corresponding to one segment of ring R4. The circuits are so arranged that while relay tongue 42 registers the signal as at (a), Fig. 4, relay-tongue 41 registers the same signal one segment later as at (b). The polarity of point 50 follows the sum of the signals, and therefore reproduces a + - 0 signal as shown in Fig. 5, and this is passed on to the regenerator CCR. Transmitter XTR is run at a signal speed greater by about 1¢ per cent than that of the distributer R1, R2 and drifts out of phase. In consequence some signal elements will occupy 2 segments instead of 3, but the regenerator CCR reproduces, all signals at the correct length.

Title: Improvements in or relating to fluorescent screens, such, for example, as are used with cathode ray tubes
IPC: H01J9/22
Filed: 1931-11-19
Abstract: 391,887. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Hayes, Middlesex.-(R. C. A. Victor Co., Inc.; Camden, New Jersey, U.S.A.) Nov. 19,1931, No. 32151. [Class 39 (i).] A thin fluorescent screen layer for a cathoderay television tube, is made by depositing particles of screen material upon a surface from suspension in a liquid, e.g. by gravity, the size of the particles being such that they can adhere to the surface in the absence of a separate binding material, e.g. pulverized material screened through a mesh 270 per inch. The liquid is subsequently removed, as by draining off or by evaporation. The screen may be associated with a conductive layer or be rendered conductive in alternative ways. Zinc sulphide, zinc silicate (willemite), or calcium tungstate may be used for the screen material, and water or alcohol for the suspending liquid. A conductive coating 13, Fig. 2, may be preliminarily formed on the walls 12 of a tube which for this purpose, and for forming a screen layer on the end wall 14, may be pivotally mounted at 17 and fitted with a plug 16 to enable the tube to be rocked as desired and any liquid 18 used subsequently drained off. The conductive coating may be obtained from an alkaline solution of silver nitrate to which a reducing agent is added, e.g. an alcoholic solution of sugar. A screen layer 20, Fig. 4, may then be formed over the conductive coating 15 on the end wall 14 from a liquid suspension 18 of screen material. Alternatively a eonductive screen layer 24, Fig. 10, may be directly formed on the end wall 14 and overlap at 27 the end 25 of the conductive coating 13 on the side wall 12. The conductive screen layer 24 may be deposited from a liquid having in suspension a mixture of screen and conductive materials, e.g. 80 per cent of screen material to 20 per cent of conductive material, the heavier conductive material settling more quickly giving an under layer in which conducting material predominates and an upper layer in which screen material predominates. Alternatively the screen particles 29, Fig. 9, may be coated with conductive material 28, by suspending them in an alkaline solution of silver nitrate to which a reducing agent is added just prior to forming the screen layer. Alternatively the screen particles may be coated preliminarily, then separated, washed, and deposited from a suspension in water or other liquid.

Abstract: 444,339. Fire extinguishing and alarms. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Meyer, R. O., [Firm of] ; 23, Pappelallee, Hamburg, Germany) Nov. 12, 1934, No. 32553. [Classes 47 (i) and 47 (ii)] A fire alarm and extinguishing system comprises a series of pipes extending between the rooms &c. to be protected and an indicating chamber d with an observation window. The pipes are closed at their ends within the rooms by fusible closures a, and within the chamber d by hinged flaps f. A pressure above or below atmospheric is maintained in the pipes and in the chamber d. If fire occurs in a room, the closure a is released by fusion of the seal and is unseated by a spring, so that the pipe concerned 'is vented to atmosphere. The resulting change in pressure therein gives an alarm, for example, by visible movement of the corresponding flap f and/or sounding of a whistle embodied in the pipe within the chamber d, or the closing of an alarm switch. As shown, all the rooms in one section of a ship are connected to a common pipe b, c leading to the chamber d. The pipes c can be connected to a source of fire-extinguishing gas or liquid. When fire is detected, such medium is admitted to the pipe c, and will escape only into the room in which a closure a has opened. The outlets may be provided with sprinkling devices.
