Title: Means and method for controlling welding current sources
IPC: B23K9/10
Filed: 1964-12-21
Abstract: 1,088,112. Supply systems for arc welding. MESSER GRIESHEIM G.m.b.H. Dec. 21, 1964 [Dec. 21, 1963], No. 51825/64. Heading H2H. [Also in Division B3] In a D.C. arc welding system of the type wherein material from a consumable electrode is transferred to the workpiece in the form of droplets which short-circuit the arc at a frequency usually above 50 per second, the welding circuit is arranged to have a relatively low inductance up to a predetermined value of current, after which the inductance is increased. Thus, when a short circuit occurs the rate at which the current increases is initially high, until the said predetermined value is reached; thereafter, the rate of increase is lower because of the higher inductance of the circuit. The advantages of the arrangement in relation to droplet formation and regulation characteristics are discussed in the Specification. Suitable circuits to achieve the required effect are described with reference to Figs. 1 to 8 (not shown), these circuits including a main choke of high inductance associated with a resistor and a subsidiary choke of low inductance; the subsidiary choke determines the initial inductance of the welding circuit, the resistor sets the predetermined value of current, and the main choke determines the subsequent, lower, rate of increase of the short-circuit current as it rises to its maximum value.

Abstract: 1,154,170. Testing electromagnetic trips. BROWN, BOVERI & CO. Ltd. Nov.30, 1966 [Dec. 2, 1965], No. 53631/66. Heading G1U. A delayed action, current dependent electromagnetic trip is tested in two stages by (a) disconnecting the restoring spring and measuring the force produced on the armature as a function of different applied current and (b) reconnecting the spring, applying weights to the armature and determining the times taken for the trip to operate as a function of the applied mechanical force. Operating time as a function of applied current can then be plotted. This procedure facilitates adjustment, since the operating time can be adjusted relative to the applied weight. Furthermore overall testing time of a batch of trips is reduced since stage (b) need be performed on only one or two trips from the batch, and the major variations in the trips, due to variations between current and armature force, may be tested in stage (a) in a continuous manner.

Abstract: 1,131,988. Punching dies. NATIONAL GYPSUM CO. 7 Dec., 1966 [23 March, 1966], No. 54855/66. Heading B6C. [Also in Division B3] A process for forming an arcuate metal printing plate for mounting on a printing cylinder comprises forming a flexible male pattern, forming an arcuate refractory female mould from said flexible male by investing the pattern with a refractory moulding material while the pattern is bent into an arc of the desired curvature, removing the male pattern and finally filling the female mould with molten metal. The flexible male pattern may be formed of cured, room temperature vulcanizing silicone rubber, the refractory female mould being made from the rubber male pattern by firing the refractory after removing the pattern. The flexible male pattern may be formed by cutting the desired image in a flat rigid female mould and forming a flat rigid male pattern by filling the mould with a hardenable liquid casting material such as a low melting or fusible alloy or resins, e.g. epoxy resins, phenolic resins. A second flat rigid female mould is then made from this rigid male pattern by investing the male pattern with a resinous, hardenable liquid casting material and the flexible male pattern results from filling the second flat rigid female mould with a liquid casting material which, upon hardening, remains flexible. In an alternative process the flat rigid male pattern is used to make a flat flexible female mould which is coated with a suitable release agent before being filled with the flexible material necessary for the flexible male pattern.
