Title: Improvements in electric welding control systems
IPC: B23K11/24
Filed: 1950-07-20
Abstract: 671,628. Control systems for resistance welding. BRITISH THOMSON-HOUSTON CO., Ltd. July 20, 1950 [July 27, 1949], No. 18149/50. Class 38 (iv). Back - to - back thyratrons 17, 18 form, when a switch 43 is in the hand position, part of resistance arm 14-16b of a phase shifting bridge 12-16b controlling the firing valves 7, 8 of ignitrons 5, 6 through which a resistance welding transformer 2 is supplied, the control arrangement for the thyratrons being such that, upon closure of a weld-initiating switch 46, they become progressively more conducting and so gradually advance the firing of the ignitrons as the weld proceeds. Resistors 41, 42, in shunt with the thyratrons, determine the initial firing points of the ignitrons, whilst the final firing points are determined by resistors 14, 15. Resistors 35, associated with each thyratron control circuit, govern the rate of change of firing. The thvratrons each have similar control circuits, energized from a transformer 23 supplied through a network 24, 25 such that the voltages induced in secondary windings 23b, 23c lag the anode-cathode voltages of the two thyratrons by 90 degrees. Normally, each thyratron is held off by negative grid bias supplied by a condenser 30 which is charged from a secondary winding 23d (or 23e) of transformer 23 over a rectifier 28 and contacts 32a (or 32b) of a relay 32. Condensers 33 are also charged from these secondary windings (over rectifiers 34), but with a polarity reverse to that of condensers 31. When the initiating switch 46 is closed, relay 32 picks up and disconnects condensers 31 from windings 23d, 23e and connects them to condensers 33 through resistors 35. The hold-off bias is thus first progressively reduced and then builds up with reversed polarity, so that the thyratrons eventually become conducting and then fire progressively earlier in the anode voltage cycle as the reversed bias voltage increases. Control by the thyratrons may be dispensed with by moving switch 43 to the right, when a resistor completes the resistance arm of the phaseshifting bridge.

Title: Improvements in pantographic mechanism for grading machines
IPC: A43D8/10
Filed: 1933-06-26
Abstract: 405,534. Pantographic apparatus. AKTIEBOLAGET LINHAM, 46, Fridhemsgatan, Stockholm.-(Assignees of Dieden, T. ; Karlslund, near Orebro, Sweden.) June 26, 1933, No. 18197. Convention date, June 30, 1932. [Class 97 (iii).] In a pattern - grading machine, particularly for shoe making, the pantographic lever for transmitting movement in the length or width direction from a controlling member, e.g., a model follower, to a controlled member, e.g., a scriber, punch, work holder, model holder or carriage, is pivoted directly to one member and connected to the other member by a link which may be adjusted to make different angles to the direction of movement of the members according to the magnification required. The arrangement provides distortionless grading at all points. In the apparatus shown, which is similar to that described in Specification 400,563, a beam 4 running on tracks 2, 3 on the base frame 1 has travelling thereon a carriage 5 carrying a punch 7 and a carriage 6 carrying a model follower 9. The material in which the graded pattern is to be formed is held in the clamp 10 and the model pattern is clamped to a table 11 travelling in tracks 12 on the frame 1. Pantographic mechanism connecting the carriages 5, 6 comprises a lever 18 pivoted at 19 to a slide 20, which may be adjustably secured by clamping screw 21 to the carriage 5, and at 22 to a second lever 23 having an end part sliding in the diametrical bore in a pivot stud 24 rotatably mounted on an extension 4a of the beam 4. The levers 18, 23 are clamped together in adjusted angular relation by the screw 25. A slide 17 on the lever 18 is rotatably mounted at 16 on a link 14 pivoted at 15 to the carriage 6. A clamp 30 secures the link 14 to a disc 31 fixed to the carriage 6 so that the movement of the slide 17 is confined to a path parallel to the beam 4 and distortion of the reproduction is avoided. In setting the link 14, an index slide 28 is moved over a scale 27 on the link to a position corresponding to the size of the model pattern and the link is rotated about the pivot 15 until the slide 28 coincides with a graduation on the disk 31 corresponding to the desired size of the graded pattern. Similar pantographic mechanism connects the extension 4a of the beam 4 to the table 11.
