Title: Improvements relating to printing telegraph systems and apparatus with multiplex transmission
IPC: H04L17/30
Filed: 1922-07-05
Abstract: 204,773. Siemens Bros. & Co., Ltd., and Gordon, A. July 5, 1922. Type-wheel machines; case-shift mechanism.- In a type-printing telegraph system for multiple working, employing a distributor for distributing the typeselecting positive and negative impulses (as in the Baudot system) in the receivers and for distributing the messages to a number of receivers each receiver has electrical combining arrangements, a type-wheel, and printing magnet, the distributor and all the receivers being driven by a common power unit. Fig. 1 shows a distributor 2 for use with four receivers, only one receiver 16 with the corresponding distributor segments being shown. The shaft 3 which carries the distributor brush 5 and the receiver contact arms 19 and typewheels 23, Fig. 2, of all the receivers, may be jointed or flexible if necessary to allow non- alignment of the receivers. The figure shows a receiver for a five-unit system of positive and negative impulses distributed to polarized relays 11 - - 15, Fig. 1, 111, 121, 131, 141, 151, Fig. 2. The receiver has six contact rings 26, 29 - - 32, 34, in which each ring has twice as many segments as the next adjacent ring progressing inwards with the exception of ring 32 which has an additional segment 33. The setting of the polarized relay armatures determines through which of two available paths a circuit shall be completed by brushes 20, 21, 22 bridging the rings in pairs. Thus each combination of impulses selects a path through one only of the segments in ring 26. Passage of brush arm 19 over segment 33 charges a condenser 35, which is discharged through the printing magnet 24 as the arm passes over the selected segment of ring 26, at which time the corresponding character on the type-wheel is opposite the printing hammer 25, except in the case of segments 27, 28, which are appropriated to letter and figure shift of the type wheel. The type wheel 23 carries two sets of type characters, is of steel, and is splined to the shaft 3, so as to be axially movable to either of two positions to bring one or other of the sets of characters in line with the hammer 25. The movement is affected by discharge of the condenser through one or other of two magnets, not shown, disposed on opposite sides of the wheel and connected respectively to the segments 27, 28.

Title: Improvements in and relating to dynamo electric machines
IPC: H02P9/14
Filed: 1942-12-28
Abstract: 561,289. Dynamo-electric machines. PARTINGTON, W., and METROPOLITAN. VICKERS ELECTRICAL CO., Ltd. Dec. 28, 1942, No. 18435. [Class 35] An alternator driven at variable speeds and supplying a fluctuating load has an automatic regulation system of the kind wherein the main excitation of the machine, or its exciter, is supplemented by an exciting current proportional to the output current of the machine and supplied through a rectifier from its output circuit, and in which further excitation, proportional to the output voltage and also obtained through a rectifier from the output circuit, opposes the main excitation, changes in output voltage being minimised in accordance with the invention by including in the circuit providing the opposing excitation an impedance having non-linear current-voltage characteristics such that the opposing excitation changes in greater proportion than the output voltage. The impedance is preferably a silicon carbide ceramic material, preferably that known under the Registered Trade Mark "Metrosil." Fig. 1 shows an alternator 1 driven by a motor 11 and supplying current through a current transformer 18 and a condenser 4 to load terminals 2, 3. The main excitation is provided by a winding 5 supplied with direct current through a variable resistance 7 from terminals 8, 9. The secondary 19 of the current transformer also supplies current in proportion to the load to the winding 5 through the rectifier 20. An opposing winding 6 receives current from the output terminals 2, 3 through a rectifier 21 in series with a non-linear resistance 22 and regulating resistance 23, the current to the coil 6, therefore, being proportional to the voltage across the terminals 2, 3. Alternatively, or in addition to the resistor 22, a non-linear resistance may be provided as at 24. The potential across the terminals 8, 9 is obtained by the voltage drop across a non-linear resistance 16 in series with a shunt winding 15 of the motor 11, the resistance serving to maintain constant the speed of the motor in spite of fluctuations in supply voltage across the input terminals 13, 14. The current transformer 18 may be designed to take a large magnetising current, or, alternatively, the secondary 19 may be shunted by a choke, in order that the current fed back into the winding 5 may increase with increase in frequency of the alternator. In a modified arrangement, Fig. 2, a separate opposing winding is omitted, the opposing excitation being obtained by connecting the rectifier 21 in series with a resistor 31 across the main winding 5 and feeding the rectifier with current from a potential transformer 32. A non-linear resistance 22 is included in the secondary circuit in the transformer. The current supplied by the secondary winding 19 of the current transformer 18 is also supplied to the winding 5. Fig. 3 shows a further arrangement in which the opposing excitation is obtained through a rectifier 21 delivering current to a resistor 40 arranged in the circuit of the winding 5.

Title: Improvements in or relating to electric arc welding
IPC: B23K9/00
Filed: 1942-12-31
Abstract: 563,216. Uniting by fusion. PEILLON, P., SARRUF, N., and CASTRO, L. Dec. 31, 1942, No. 18626. [Class 83 (iv)] Metallic-arc welding is effected by striking the arc and completing the weld beneath the surface of a body of non-conducting liquid. The liquid may be a hydrocarbon such as a mineral oil. The electrode may be flux-coated and the coating may be impregnated or coated with a protective varnish or other compound such as polyvinyl chloride to render it impervious to the liquid in which the weld is effected. Repairs may thus be effected in the interior of vessels or pipes for conveying or storing oil without emptying such vessels or pipes and in some cases even without interfering with the continued use of the apparatus. In one process, two mild steel plates may be laid edge to edge in a tank containing mineral lubricating oil and welded by a flux-coated mild steel electrode, such as is used in air, but further coated with polyvinyl chloride. The electrode may be arranged at an angle of 30 degrees to the plane of the plates with the flux resting on the plate. As the electrode burns away it may be fed down parallel to itself, the angle of the electrode remaining constant. In another process a cracked iron casting, after chipping to form a groove, is immersed in a tank containing oil and welded with a mild steel electrode as in the previous form. According to the Provisional Specification, inert or reducing gases may be fed to the welding point. Specifications 8642/07, [Class 83], 395,663 and 559,033 are referred to.
