Title: Television Circuitry
IPC: H04N9/29
Filed: 1967-02-07
Abstract: 1,175,418. Cathode-ray tube circuits. WESTINGHOUSE ELECTRIC CORP. 7 Feb., 1967 [24 Feb., 1966], No. 5809/67. Heading H4T. The degaussing coil for the display tube of a colour television receiver is utilized during stand-by periods of the apparatus as an inductive reactance in series with the primary of the mains transformer to allow the heaters of the tube and receiver valves to continue to be operated at a reduced current during such periods so that when subsequently switched-on the receiver commences to operate within about six seconds. Thus referring to Fig. 1, during stand-by periods, with the linked switches 28, 37 in the positions shown, the degaussing coil 10 is connected in series with the A.C. source 20 and the primary winding 32 of the mains transformer 34 the impedance of coil 10 being e.g. equal to that of the winding 32 so that the tube heater 3 and the valve heaters 62, 64-70 connected to respective secondary windings 49, 60 are supplied with one-half their normal operating voltage, the H.T. circuit, however, being interrupted by switches 37. When normal reception is required the switches are operated to their other position thus restoring the H.T. supply to terminal 48 and connecting the A.C. source 20 to the primary winding 32 through a thermistor 74 and via the latter and a varistor 76 to the degaussing coil 10. An A.C. magnetic field is produced in the latter which, as the resistance of the thermistor drops due to increasing temperature and that of the varistor 76 increases, due to the decreasing voltage across it, decays rapidly to a very low value and so effects the required degaussing. During this short decay period the pre-heated heaters reach their full operating temperature and normal receiver operation commences. The structure of the degaussing coil assembly is depicted in Fig. 2 (not shown).

Title: Improvements in the manufacture and production of dyestuffs
IPC: C09B47/08
Filed: 1936-02-28
Abstract: Dyestuffs are produced by heating chlorinated or brominated phthalocyanines with organic hydroxyl compounds or their metal derivatives.  The starting material may be a free chlorinated or brominated phthalocyanine or a metal derivative; examples are tetrachlor-phthalocyanine, copper phthalocyanines containing 4, 5 and 14 atoms of chlorine per molecule, and copper phthalocyanines containing 25, 45 and 47 per cent of chlorine.  Suitable hydroxyl compounds are monohydric and polyhydric alcohols of the aromatic and aliphatic series and hydroxy compounds of the benzene, naphthalene and anthracene series; these are generally used in the form of their alkali metal derivatives and either singly or as mixtures, and also in the form of their nitro-, amino- and halogen compounds.  Examples are alpha- and beta-naphthol, hydro-quinone, phloroglucin, amyl, dodecyl, cetyl, butyl, hexyl and benzyl alcohols, p-hydroxy-benzaldehyde, 8 - hydroxyquinoline, 1 - hydroxyanthraquinone, 1 : 5 - dihydroxynaphthalene, phenol, p-cresol, cyclohexanol, resorcinol.  As diluents excess of the free hydroxyl compound or substances which do not take part in the reaction may be used, such as naphthalene, alkylnaphthalenes, aromatic nitro - hydrocarbons, dialkylanilines, pyridine, quinoline; it is advantageous to work under pressure.  Metals which favour the splitting off of halogen may be added, e.g. copper or silver powder. When starting with a metal-free phthalocyanine, the replacement of the halogen and the introduction of a metal into the dyestuff may take place simultaneously.  Samples have been furnished under Sect. 2 (5) of (1) a blue compound formed from a brominated copper phthalocyanine and alpha-naphthol, and (2) a blue-green compound formed from a copper phthalocyanine containing both chlorine and bromine, and alpha-naphthol.

Filed: 1930-02-26
Abstract: 353,485. Supply meters; interrupters. FERRANTI, Ltd. and HOLMES, W., Hollinwood, Lancashire. Feb. 26, 1930, No. 6411. [Class 37.] Apparatus for the summation of electrical energy from or at a number of points includes means for adding the motion derived from individual impulses received from meters at the different points. On each meter shaft is a cam 21, Fig. 8, operating between antifriction rollers 22, 23 mounted in jewelled bearings, thereby oscillating a blade 36 pivoted at 17 and carrying a contact 18 which operates between fixed contacts 19, 20. The circuits of electromagnets 5<1>, 6<1>, Fig. 4, are thereby alternately closed, causing operation of an armature 1, pivoted at 2<1> and carrying phosphorbronze strips 2 which prevent contact with the polepieces, minimize wear, and assist return of the armature to its central position. The armature carries a phosphor-bronze strip 41 which oscillates a pair of discs 5 through a link 7 thereby rotating a ratchet wheel 11 through one tooth for each oscillation. Rotation through more than one tooth is prevented by an escapement 15, 16, Fig. 2. A ratchet wheel 11 is provided for each meter, the motions of the different wheels being added by differential gearing, Fig. 2 shows apparatus for adding the motions derived from two meters. Each ratchet wheel 11 is fixed to a sleeve 12, which is freely mounted on a spindle 13 and is connected to a sun wheel s by springy wires 14 for reducing shock. Each sun wheel s engages one of a pair of mutually meshing planet pinions p mounted on a carrier plate c rigid with the shaft 13. The shaft 13 drives, through spur gearing, a shaft 22<1> which operates counting mechanism (not shown). A shaft 23<1> is geared to the shaft 22<1> through a gear wheel 24 which is connected to the shaft 221 by a spring (not shown) which normally keeps a pin 26 on the wheel 24 in engagement with an arm 27 on the shaft 22<1>, but allows nearly a complete rotation of the shaft if the wheel 24 is held stationary, thus smoothing out any irregularities in the drive. The shaft 23<1> carries an aluminium disc 30 rotating between the poles of a permanent magnet 31 to assist in the smoothing action. The shaft 23<1> also carries cams 22 which operate switches similar to that shown in Fig. 8 for operating demand indicators &c. The whole apparatus is mounted on a plate which is hinged so that it can be swung forwards to expose the connections at the back. The Provisional Specification describes also the demand indicator forming the subject-matter of Specification 351,973.

Abstract: 1377432 Automatic control of position TOKYO SHIBAURA ELECTRIC CO Ltd 11 Feb 1972 [18 Feb 1971] 6555/72 Heading G3N A control system for positioning a electrohydraulically moved member comprises a comparator for comparing signals representative of the actual and desired positions of the member to produce an error signal, a controller which receives the error signal and moves the member in response thereto and detector means which compares the error signal with a datum level and increases the lag characteristic of the controller when the error signal is less than the datum level. The desired position, in binary coding is entered into counter 12. Transducer 11, connected to electro-hydraulic member 10 generates pulses corresponding to displacement of member 10 and these pulses count down counter 12. The counter output is converted to an analogue value at 13 and this error voltage is amplified at 14, 18 and 26 and is applied to valves 27 which control member 10. The feedback circuit of amplifier 20 comprises resistor 21 and capacitor 23 which is normally shorted by relay contacts 24. When relay contacts 24 are opened, the lag of amplifier 18 is increased by the introduction of a feedback capacitor. OR gate 29 is fed by leads from all the stages of counter 12 except the lowest two. When the error voltage is fairly high, gate 29 is enabled and relay 25 holds contacts 24 closed. When the error signal is reduced so that it is only on lines Ac and/or A 1 , contacts 24 are opened and the desired log is introduced into the servo loop. In an alternative embodiment, the desired position is entered, in analogue form, into comparator 31 and is compared with the position signal from detector 33. The error signal is amplified at 14, 18 and 26 and is applied to valves 27 which control member 10. The feedback circuit of amplifier 20 comprises resistor 21 and capacitor 23 which is normally shorted by relay contacts 24. When contacts 24 are opened, the lag of amplifier 18 is increased by the introduction of a feedback capacitor. Relay 25 is actuated when the error voltage is measured at 32 as below a predetermined action, introducing the desired log into the servo loop.
