Title: Improvements in or relating to cathode ray tubes
IPC: H01J29/28
Filed: 1951-12-28
Abstract: 697,585. Luminescent screens. RAULAND CORPORATION. Dec. 28, 1951 [Dec. 29, 1950], No. 30283/51. Class 39(i). In making a cathode-ray tube in which the fluorescent screen is coated with an organic film on which a metal backing layer is deposited, the same charge of liquid is used for settling the screen and then forming the film. After the screen has settled, the bulb is tilted through a small angle A, and so maintained while the film-forming process is carried out. This is to prevent the film forming on a liquid surface which is smaller than the screen surface eventually to be covered after decanting off the liquid. The angle of tilt may be from 5 degrees to 20 degrees, depending on the configuration of the bulb and the amount of liquid, and is defined in terms of dimensions of the liquid surface produced. The least depth d of the liquid is similarly defined. Suitable compositions are given for the fluorescent screen,.the film solution, and the settling liquid: and the metal backing may be aluminium, lithium, beryllium, or magnesium. Specification 645,633 is referred to. Reference has been directed by the Comptroller to Specification 656,531.

Title: Stabilised vacuum tube oscillators
IPC: H03B5/14
Filed: 1939-11-18
Abstract: 533,736. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. Nov. 18, 1939, No. 30329. Convention date, Dec. 20, 1938. Addition to 510,379. [Class 40 (v)] [Also in Group XXXIX] In a generator as claimed in the parent Specification in which stability of frequency and amplitude is obtained by a bridge circuit in the reactive coupling, negative feedback is provided in the amplifier to produce optimum phase shift. The Figure shows an arrangement for producing two frequencies, determined by the bridges 60, 601, in which negative feed-back is provided by the coupling 16. The phase shift in the negative feedback path is preferably zero and the amount of feedback large. The amplitude of oscillation is stabilised below overload value by the temperature dependent non-linear resistance elements RT, RT<SP>1</SP> heated in parallel by the tuned transformer 29. The effect of room temperature may be obviated by the use of a heat insulated chamber and the resistance elements may operate as described in Specification 506,791. The modulation in the amplifier may be tested by a transformer 91 tuned to the difference frequency and applied to the non-linear resistance element 93 and transmitted over lines 96 to a central station. Power for the amplifier may be transmitted over a cable from a central station, tubes of low filament consumption being used and heated from a transformer 85, preliminary heating being effected by battery 87. The circuit, in addition to generating, may amplify a broad band of frequencies applied to input 'transformer 12. As shown a bridge output circuit is used and the reactive coupling circuits are arranged in series with the input from transformer 12. A bridge circuit may be used in the input and only a single frequency may be generated, Fig. 1 (not shown). The time constants of the non-linear resistance element are arranged to be large compared with the operating frequencies but less than the time for oscillations to build up and decay. The Specification, as open to inspection under Sect. 91, comprises also a circuit having a single reactive path with the omission of the amplitude limiting elements RT and the series circuit 75 which restricts feedback to the generated frequency, in which the bridge 60 is so adjusted as to balance at the resonance frequency of the arm Z thus producing a highly selective amplifier transmitting from line 10 to line 11. This subject-matter does not appear in the Specification as accepted.

Title: An ac elevator controlling apparatus
IPC: B66B1/34
Filed: 1968-06-26
Abstract: 1,219,807. Control of A.C. motors. HITACHI Ltd. 26 June, 1968 [28 June, 1967], No. 30461/68. Heading H2J.  In a control system for at least one induction motor for a lift, the magnitude or timing of changes in torque after the first are selected so as to restrain vibrations of the cage in the vertical direction caused by the previous change in torque. The period of vibration of the cage is calculated from the mechanical characteristics of the suspension rope, its effective length and the weight of the cage &c. and an RC circuit controlling the " notch interval " between successive operation of accelerating or braking contactors is set according to formulae given which take account of the period and the number of notches. Since the period will vary according to the position of the cage in its shaft and the load carried by the cage, the notch interval may be set according to average values for these variables or the timing circuit may be adjusted by position detectors and/or a load detector. A single, pole changing motor may be used or two separate motors of different pole numbers and various embodiments are described in which they are connected to a threephase supply either directly or through one or more stages of series resistors. Regenerative braking (also time controlled) is provided by switching from the high-speed to the low-speed machine or winding, with series resistors interposed in some cases. An electromagnetic brake is applied when the motors are de-energized and allowance is made for the delay which occurs between flow of release current and actual release.
Patent GB-799921-A (GB)
Title: Improvements relating to the production of cobalt compounds
Inventor: WEST DEWITT HENRY
IPC: C01G51/04
Filed: 1954-10-22
Abstract: Organic cobaltous salts or soaps are obtained by dissolving in the appropriate acid, cobaltous oxide obtained by reduction of cobaltosic oxide (see Group III).  Specified acids in which the oxide may be dissolved are formic, acetic, oxalic, citric, naphthenic, 2-ethyl-hexanoic and tall oil; with naphthenic acid a temperature of 160 DEG  C. is suitable for the dissolution of the oxide.  Such salts or soaps may also be obtained by further reaction of a cobaltous compound obtained by such a process; e.g. cobaltous naphthenate may also be prepared by reaction of cobalt sulphate produced from the cobaltous oxide of the invention with sodium naphthenate.ALSO:A brown cobaltous oxide is produced by heating cobaltosic oxide in a mixture of oxidizing and reducing gases, the ratio of said gases being dependent on the temperature and determined by a graph (not shown). The reducing component of the gases may be hydrogen and/or carbon monoxide and the oxidizing component steam and/or carbon dioxide: steam/hydrogen, steam/water gas, steam/producer gas and carbon dioxide/carbon monoxide mixtures are specified.  Preferred temperatures are 350-450 DEG  C.  Immediately after carrying out the reduction it is desirable to quench the oxide in water or cool rapidly in an inert or weakly reducing atmosphere-e.g. after having passed continuously through a tunnel furnace on trays the oxide may be tipped on to a conveyer leading to a water quench tank.  The oxide thus produced is soluble in inorganic acids such as hydrochloric, nitric, sulphuric and phosphoric to form cobaltous salts.  In a continuous process, the wet mass of oxide may be transferred to vats containing hot sulphuric acid, the mixture filtered and any undissolved oxide returned to the tunnel furnace and there mixed with fresh cobaltosic oxide.

Filed: 1923-12-04
Abstract: 207,834. Felten &. Guilleaume Carlswerk Akt.-Ges. Dec. 4, 1922, [Convention date]. Drawings to Specification. Phantom-circuit systems; induction, preventing and minimizing.-In a phantom circuit system, want of balance, giving rise to cross-talk, is corrected by the insertion of compensating impedances, such as chain conductors, or adjustable resistances in series with a variometer, the latter having one coil in each line of a pair, between the instruments and the ends of the wires. The elements forming the chain conductor are so chosen that the effective resistance and reactance of this conductor depend upon frequency according to a law which imitates that followed by empirical adjustable impedances, chosen so as to eliminate cross-talk at various fixed frequencies. The Specification refers to known methods in which adjustable impedances comprising resistances shunted by capacities are connected between the ends of the wires and earth, and subsequently replaced by a series of resonant circuits corresponding to outstanding values of the original impedances.
