Patent GB-358983-A (GB)
Title: Improvements in or relating to telephone systems
IPC: H04M15/10
Filed: 1930-07-16
Abstract: 358,983. Automatic exchange systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, GILLINCS, C., 28, Eldred Road, Mossley Hill, and BELAS, F. T., 24, Stanley Street, all in Liverpool. July 16, 1930, No. 21595. Grant of Patent opposed. [Class 40 (iv).] Multiple metering is controlled by a single switch which rotates continuously during conversation, its bank being variably marked in accordance with the zone of the called subscriber. Fig. 1 shows the application to the system described in Specification 265,971, [Class 40 (iv), Telephones &c.], in which relays 206A, 207A are selectively operated according to the setting of a bidirectional zone-marking switch. When the called party replies, relay 202A energizes and connects relay 204A to an interrupter CNC, of which the speed of rotation may be varied in accordance with the time of day. The magnet TZM steps the metering switch as long as conversation continues, and each time a terminal marked by relays 206A, 207A is engaged, relay 203A operates and applies booster battery to the test wire 10. Fig. 4 shows a modification in which the bank of the metering switch is marked directly by a vertically moving wiper VW. Fig. 5 shows the application of the latter arrangement to a first code selector, the switch RXF which gives access to the register controller being used as the metering switch. The switch RXF returns home after the register controller has completed its operation, and when relay D energizes in response to the reply to the called party, relay DA pulls up and connects an interrupter to relay DB, thereby causing the magnet RXM to rotate the switch RXF as long as conversation continues. The additional bank 7c is marked over the vertically moving wiper VW, and each time a marked terminal is engaged, relay J energizes and connects booster battery to the test wire 11, while at the end of each metering cycle a warning tone is applied to the upper speaking wire. A relay MG provides an intermittent holding circuit for the release relay B during the homing of the switch RXF.

[Class 40 (iv)] In the system described in the parent Specification, the register-translator or converter (Figs. 42-47) at the central exchange, instead of having a relay register for each digit of the wanted number, is provided with onlya single relay register which is set in succession by the appropriate registers of the toll control circuit (Figs. 32-41), the sequence-control switch being advanced as the digits take effect. As in the prior arrangement, the zone digits set a bi-directional switch which controls the transmission of up to five non-decimal trains of impulses, and the next digit from the toll control circuit is retained in the register until those trains have been sent. The first train may be varied according to the grade of the outgoing junction. The converter sends D.C. impulses substantially as in the prior arrange-- ment, and these are repeated in the toll control circuit as A.C. impulses. Specification 532,729  is referred to.

Patent GB-835789-A (GB)
Title: Improvements in or relating to cathode ray tubes
IPC: H01J31/20
Filed: 1956-07-18
Abstract: 835,789. Cathode ray tubes. PHILCO CORPORATION. July 18, 1956 [July 18, 1955], No. 22219/56. Class 39(1). In a cathode ray tube having a screen structure composed of a plurality of electron impingement responsive elements and an electron source for forming a plurality of electron beams focused to cross over in the region of a yoke which deflects the beams over the screen, the beams cross over substantially in the centre of that yoke, the yoke centre being defined as that point in the space surrounded by the yoke in which there is substantially no change in the magnetic field strength for a minute displacement therefrom in any direction. This is stated to reduce the " corner twist " error for example in a colour television receiving tube where the video beam and indexing beam are relatively twisted at the corners of the screen and it is alleged that if these beams do crossover substantially at the yoke centre then such corner twist error as remains is not due to changes in the distribution of windings in individual yokes, thus making it possible to design a screen whose elements or strips are so arranged that the two beams track throughout the scan. The crossover point may be altered by moving the yoke longitudinally along the tube neck or by shifting the position of the focusing magnet. Preferably however use is made of the " skew and convergence correctors". Alternatively an internal convergence control in the electron gun may be utilised. The final accuracy of these correctors may be tested by energising suitable coils on the deflecting yoke so as to produce two opposite alternating magnetic fields transverse to the longitudinal tube axis and of approximately equal intensity and varying the cross-over region of the beams until the area of each of the beams on the screen is a minimum. The screen 26, Fig. 3a comprises strips of phosphors 31 in three primary colours deposited on the inside of the tube faceplate 27 and are of such a configuration that a line 36, Fig. 3b, tangential to any projection 31a of a strip 31 on the plane 28 tangential to the faceplate at its centre, makes an angle α with the vertical axis y such that   α = 1À11 XY radius / Z<SP>2</SP> where X, Y are the coordinates in inches shown in Fig. 3b and Z is the distance in inches from the yoke centre/beam crossover point to the centre of the screen 26.

Filed: 1935-08-07
Abstract: Acids of the type of crotylidene cyanacetic acid, which are obtainable by the condensation of an a -b -unsaturated aldehyde with cyanacetic acid, or derivatives thereof are polymerized by treatment with a free base or substances exhibiting an alkaline reaction in aqueous solution.  Suitable bases include piperidine, diethylamine, triethylamine, caustic alkalies and alkali carbonates.  The polymerization may be effected in the presence or absence of a solvent or in emulsion.  In examples: (1) a solution of sodium salt of crotylidene cyanacetic acid in water mixed with caustic soda lye is allowed to stand and the polymerization product recovered by precipitation with acid; (2) the butyl ester of crotylidene cyanacetic acid is emulsified in an aqueous sodium carbonate solution containing a neutral emulsifying agent and after standing the resin is precipitated by means of hydrochloric acid; (3) the butyl ester of crotylidene cyanacetic acid is polymerized in the presence of piperidine.  The butyl ester of crotylidene cyanacetic acid is prepared by esterifying crotylidene cyanacetic acid with butyl alcohol in the p  presence of hydrochloric acid.
