Title: Welding power supplies
IPC: B23K9/073
Filed: 1975-11-27
Abstract: 1528395 Automatic control of welding STK GES FœR SCHWEISSTECHNISCHE KONSTRUKTIONEN mbH 27 Nov 1975 [28 Nov 1974 8 Oct 1975] 48880/75 Heading G3R [Also in Division H2]  In an arc welding apparatus in which power is supplied to the welding electrode via a three phase transformer 10 and thyristors SCR1-SCR3, a circuit for controlling the firing points of the thyristors enables regulation of the welding current or voltage. The potential at the welding electrode is applied via trimming resistors R5, R6 to a potentiometer R4, the setting of which determines the firing point of the thyristors and therefore also the power supplied to the welding electrode. Three control circuits, each including a transistor T1, a uni-junction transistor T2 and a trigger transformer TR are supplied with D.C. from respective bridge rectifiers GL connected to the secondary windings of a three phase control transformer (not shown). The setting of the potentiometer R4 controls the conduction of the transistor T1 which controls the rate of charging of a capacitor C. When the capacitor voltage is sufficient to break-down the transistor T2, a firing pulse is supplied by the transformer TR to the thyristor. If the welding voltage increases, the conduction of the transistor T1 is increased and the potential at point P is reduced. The capacitor C charges more slowly thereby retarding the instant in the half cycle that the transistor T2 beaks down. The thyristors SCR1-SCR3 are consequently fired later in the half cycles to reduce the voltage. The circuit may be modified to regulate the welding current by using transducers, current transformers or opto-electrical couplers.

Abstract: 1363528 Thin film resistors; thin film capacitors WESTERN ELECTRIC CO Inc 4 Nov 1971 [6 Nov 1970] 51312/71 Headings H1S and H1M A method for adjusting a parameter of a thin film device, e.g. a capacitor, or resistor which may be made of tantalum, tantalum nitride or other suitable material, comprises the application of an anodizing current to the device in a series of discrete steps, the size of the current and the time of application being characterized in that the per cent change at each step in the deviation of the parameter from the desired value is an approximately constant fraction of the change in the preceding step, preferably this fraction being ¢. In one embodiment of the invention with a starting deviation of say- 5%, and with a required finishing tolerance of say + 0À1%, the process of adjustment is made in ten steps according to the formula I n T n  = 2<SP>-n</SP>I 0 T 0 , I n  and T n  being the size of the current and time of application, respectively, in the nth step, the process starting with n=0, and finishing with n=9. 9. In a preferred embodiment of the invention, the adjustment of the product I n T n  is made in two phases: (i) adjustment of the time of application of the current with the size of the current held constant, (ii) adjustment of the current with a constant time of application. If the steps are considered as taking place in reverse order, i.e. starting with n = 9 and finishing with n = 0, a stage is reached where, unless the anodizing time is increased, the current necessary to produce the required per cent change is of such a large value that it may cause damage to the film. When this stage is reached (called the cross over point "X"), a change is made to the second phase, which is phase (ii) in the forward order actual performance of the sequence of anodizing steps. In a modification of the above method, the said steps may be made by the employment of a linear approximation of the above formula. The above described process may be applied automatically, with the aid of a general purpose process control computer, for the adjustment of some parameter of a plurality of thin film devices either singly or two or more together.
