Title: Type printing telegraph apparatus
IPC: H04L17/26
Filed: 1937-03-25
Abstract: 475,468. Type-printing telegraphy. CREED & CO., Ltd. March 25, 1937, No. 8886. Convention date, May 22, 1936. [Class 40 (iii)] A type-printing telegraph receiver comprises a type-wheel and a ribbed drum on a shaft frictionally driven by a motor, the ribs being of different lengths and terminating at one end of the drum, rotation of which is selectively controlled by rocking an escapement pawl which is also moved longitudinally of the drum for each successive signal element. Shaft 33 driven by motor 36 'frictionally drives a cam assembly 47, 57, 81, 114 and a stop arm 54 controlled by the receiving magnet 41 in a manner not shown ; a second shaft 34 frictionally drives the ribbed drum 71 and typewheel 76. Cam 47 " flutters " the magnet armature 42 at the impulse frequency, and cam 57 oscillates a three-armed escapement control lever 64 at the same frequency with a short time lag, the escapement being effectively operated only when the armature 42 is held by the magnet so that a hook 65 is released from an arm 66 of the lever. The lever is pivoted on a shaft 67 carrying the escapement pawl 68 which has an arm 69 perpendicular to the plane of the paper engaged for operation of the escapement by the forked end of arm 61. of the control lever 64, the escapement lever being moved axially of the ribbed drum 71 for successive signal elements by cam 81 (stepped or helical) and lever 77, Fig. 2, which shifts the escapement shaft 67. The ribs on drum 71 extend for varying distances from its left-hand side as shown in Fig. 7 so that the drum is permitted to rotate through successively decreasing angles as the escapement moves to the left. Printing and paper feed are controlled by cam 114 and lever 112, the printing hammer 103 being operated by a ratchet wheel 108 quickly operated by pawl 109 when lever 112 drops off the hump on the cam, and the paper being fed gradually by ratchet 99 and pawl 101 when lever 112 mounts the cam. The two arms 116, 117 of the escapement may be offset as shown in Fig. 7, and to ensure that the drum has time to move through the large angle required for the first signal element if marking, the escapement arm 117 has a pin 123 engaged by a cam 122 at the right-hand end of the drum so as to hold arm 117 clear of the drum until the longest rib has passed the tooth on arm 117. The pin is ineffective after the first signal element since it is moved to the left clear of the cam.

Title: Improvements in or relating to apparatus responsive to the phase difference between two voltages
IPC: H03B13/00
Filed: 1935-03-23
Abstract: 451,618. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. March 23, 1935, No. 9137. Convention date, March 23, 1934. [Class 38 (iv)] [See also Groups XL and XXXVI] Oscillation frequency; power factor.- In a device responsive to the phase angle between two voltages, one voltage E<1> controls the intensity of a stream 22 of electrified particles in an electric discharge device 13, the other voltage E<2> deflects the stream and plates 20, 21 with overlapping and longitudinally spaced edges as shown intercept the stream on either side of its mean path so that the voltage V<1> between the plates 20, 21 varies with the phase angle between the voltages E\ E<2>. As shown, the stream 22 is a cathode ray passing a focusing electrode 16 and an anode 15 in the form of a coating on the wall of the tube 13 and the ray may be sharply focused or broad or in the form of a flat sheet. The voltage E<1> is applied to the grid 17 and the voltage E<2> to deflecting plates 24, 25. The plates 20, 21 are connected together through a resistance 27 which may be such that the potentials of the plates are time integrals of the ray currents to the plates or such that these charges on the plates leak off rapidly. The overlapping edges of the plates produce the effect of zero transverse displacement so that the ray never passes between the plates. To eliminate errors due to external fields, two tubes 13 may be connected in parallel with opposite deflecting and collector plates connected together, Fig. 4 (not shown). A radio-frequency valve-oscillator is synchronized with a principal oscillator by deriving the voltages E<1>, E<2> from the two oscillators and using the voltage V<1> to control the valve-oscillator as by varying the bias on its grid, Fig. 5 (not shown), and the connections may be such that the voltages E<1>, E<2> are in quadrature, and the voltage V<1> zero, when the oscillators are in phase. A regenerative receiver is kept at maximum regeneration without oscillating by keeping the power-factor of the grid circuit small but not zero, Fig. 6 (not shown), the voltages E<1>, E2 being derived from the voltage and current in the inductance in the grid circuit and the voltage V<1> controlling the degree of coupling of the grid and anode circuits as by varying the grid bias.

Title: Improvements in and relating to toy or model electric railway systems
IPC: A63H19/24
Filed: 1957-03-20
Abstract: 888,001. Model electric railways. WINSTANLEY, J. E. March 20, 1958 [March 20, 1957], No. 9167/57. Class 132(3)  Apparatus for controlling signalling, points operation and track current at junctions of a model electric railway system comprises a switch having one pole for energizing one or other of two signal branches, a second pole for operating a points mechanism, and a third pole, or a third pole and a fourth pole, for controlling current supply to two track sections. In Fig. 3, a wafer switch unit 10 includes four radial ganged poles 11-14. With the switch in one of its limit positions, control current passes via pole 11 through red and green indicating signal lights 3<SP>1</SP>, 2<SP>1</SP>, route indicator light 18 in the unit is energized through pole 12, and traction current to a line 24 passes through the pole 13. Traction current to a line 25 passes via pole 14 through a red indicator light 25a the resistance of which is such that insufficient current is available to run a locomotive on a section supplied by the line 25. In moving the switch towards its other limit position, pole 11 causes signal branches 16, 17 to be momentarily energized and both signals show amber by the illumination of the red and green lights in each signal. Momentary energization of solenoids 22, 23 and operation of the points is caused as pole 12 passes over contacts connected to lines 20, 21. Upon the switch reaching its other limit position, the green signal light 2, the red signal light 3 and a route indicator light 19 are energized. Also, a red indicator light 24a is connected in series with the line 24 and pole 14 is connected direct to line 25. Traction current to the poles 13, 14 is controlled by two separate controllers (not shown). By dispensing with the lights 24a, 25a, a three pole switch may be used, Fig. 5 (not shown). Fig. 11 shows the poles of a two-bank rotary wafer switch having a bank 1 for controlling the traction current and a bank 2 for controlling current to the signals, the points and the route indicator lamps. A stop S corresponding to the amber signal position may be provided. The switch may alternatively be of the push-pull type, Fig. 10 (not shown). Arrangements of signals and point operating solenoids for facing and trailing points are shown. The signals are as described in Specification 888,002.
Patent GB-651136-A (GB)
Title: Improvements in or relating to arc welding electrodes for deep penetration welding of steel
IPC: B23K35/36
Filed: 1948-04-01
Abstract: An arc welding electrode for deep penetration welding of non-austenitic steel, e.g. in making unbevelled butt, filler &c. welds has a coating containing cryolite in proportion of 5 to 30 per cent by weight of dry powder with a silicate binder and oxides and silicates.  A high rate of transfer across the arc is thus produced and if the welding is arrested by raising the arc voltage, lateral dissipation of the stream is prevented by using a core with a higher melting point than the coating, e.g. by increasing the coating thickness or by including refractory oxides.  One example of coating for a steel wire used to form an overall diameter of not less than .25 inches on an 8 gauge wire comprises cryolite 5-20 parts, quartz 10-20 parts, silicate, e.g. mica or china clay 10-20 parts, ferro-manganese 15-35 parts, rutile 0-15 parts, iron ore, e.g magnetic and/or silicate 10-30 parts with an alkaline silicate binder.

Title: Process for converting halogen-substitution products of hydrocarbons into hydrocarbons or other halogen-substitution products of hydrocarbons containing a higher number of carbon atoms
IPC: C07C17/26
Filed: 1923-04-05
Abstract: Halogen-substituted hydrocarbons or mixtures thereof are converted with elimination of hydrochloric acid into hydrocarbons or other halogen-substituted hydrocarbons containing a higher number of carbon atoms by conducting them, in admixture with water, over certain catalysts at a raised temperature not exceeding 400 DEG  C.  The catalysts comprise metals such as platinum, non-metals such as carbon, and metallic compounds, such as ThO2, ZrCl4, Bi2O3, SnCl4 and ZnCl2, and are mounted on porous materials, particularly highly-active charcoal.  Pressures higher than atmospheric may be employed.  According to the examples, (1) methyl chloride and traces of water are passed through a tube containing finely-divided platinum mounted on asbestos and maintained at a temperature of 275 DEG  C.; the product, comprising ethyl chloride, unchanged methyl chloride and hydrochloric acid, is washed to remove the acid and the gaseous chlorides are separated either by the use of an absorbent, such as highly-active charcoal, or by liquefaction and fractional distillation of the mixture; (2) moist methyl chloride is conducted at a temperature of 200 DEG  C. over bismuth or zirconium chloride mounted on highly-active charcoal and the ethyl chloride isolated from the products; (3) a moist mixture of methyl chloride and methylene chloride, by passage over bismuth chloride on highly-active charcoal at a temperature of 280 DEG  C, yields ethylidene chloride in admixture with unchanged reaction materials and some methylal; the ethylidene chloride is separated by liquefaction and fractional distillation; (4) ethylene is obtained by passing moist methyl chloride over bismuth oxide on highly-active charcoal at a temperature of 240 DEG  C.; the ethylene is absorbed with highly-active charcoal.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of ethyl chloride instead of methyl chloride.  This subject-matter does not appear in the Specification as accepted.
