Title: Improvements in transformers for use in rectifier installations

Filed: 1928-09-10
Abstract: 296,996. Akt.-Ges. Brown, Boveri, et Cie. Sept. 10, 1927, [Convention date]. Transformers. - In transformers for feeding multi-anode rectifiers in which the secondary windings s are arranged in groups b<1> - - b<1111>, c<1> - - c<1111>, so distributed over the core limbs in relation to the primary windings p as to obtain equal distribution of current to the anodes a<1> - - a<3> that operate in parallel, the development of powerful magnetic forces between winding sections in the event of " short-circuit " current in a section due to back ignition at the corresponding anode is avoided by dividing the primary winding into groups w<1> - - w<1111> co-ordinated to the secondary groups and connected in parallel to each other. The less effective equalization of current distribution in parallel-connected anodes due to a reduction in effective inductive coupling between the separate secondary groups and the primary may be counterbalanced by the provision of chokes d, Fig. 2, in the anode leads, or by adopting the alternative winding arrangement shown in Fig. 3. In this arrangement, a section of each primary group w<1> - - w<1111> is connected in series with the main portion of an adjacent group. The separated sections may lie close to the corresponding main sections as shown or may be remote therefrom.

Title: Improvements in relays for electrical remote control systems
IPC: H02J13/00
Filed: 1934-09-12
Abstract: 423,488. Electromagnetic switches. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. Sept. 12, 1934, No. 26155. Convention date, Sept. 15, 1933. [Class 38 (v)] In an electric remote-control control system in which a number of relays are operated by trains of rapid current impulses, additional relays are provided which are so arranged as not to be operated by such trains of impulses but to respond to single current impulses of substantial duration. As shown in the Figure across one conductor of a supply system 1, and a control or pilot wire 1<a> are connected a series of relays 3 which respond to a definite number of short current impulses. An additional relay is, however provided to control the circuit of a consuming device 5 in response to a single current impulse in the control circuit of substantial duration, e.g. a few seconds, and the relay is arranged to be unaffected by the impulse trains operating the relays 3. The additional relay comprises an electromagnet 4 arranged on energization by a relatively long current impulse to attract a pivoted armature 6 against a spring 7 and allow contacts 9 in the energizing circuit of an induction disc motor 11 to close. The motor disc drives through gearing 12 .. 16 a detent 17 which normally holds down a latch 30 so that its hooked end 32 is out of the path of a projection 35 on the armature 6. With a long, steady current impulse the projection 35 has moved past the hook 32 before the latter is moved into its path by the release of the lever 30 by the detent 17. During the release movement of the detent 17 a slotted projection carried by the intermediate shaft 14 moves to the succeeding tooth of a wheel 23 so that at the end of the current impulse a cam 25 is caused to engage and close contacts 26 in the circuit of the controlled apparatus 5. If however a series of short rapid current impulses are transmitted to operate relays 3, the intermittent closing of the motor circuit by the vibrating armature 6 at contacts 9, either produces only a small series of movements of the driven members or may, in case of increased intermittent energization of the motor cause the hooked end of the lever 32 to be moved into the path of the projection 35 and arrest further vibration of armature 6. The controlled circuit of the apparatus 5 is not closed as the operating detent 18 is not moved through a sufficient angle. Any small deviations of the wheel 23 from the position shown, due to vibration of the member 18, are neutralized by a spring 27 bearing on a flattened member 24 secured to the shaft 26 bearing the toothed wheel 23 and cam 25.

Title: Improvements in the manufacture of welded iron and steel tubes
IPC: B21C37/08
Filed: 1919-10-27
Abstract: 159,539. Chisholm, D. W. Oct. 27, 1919. Tubes.-In skelping and welding iron or steel tubes, the heated strip is drawn in succession through a skelping die and a welding ring or like containing a supporting and guiding tongue which is movably mounted so that it may automatically adjust itself to the skelps, welding gas being applied to the edges of the skelp as it passes from the die to the ring. The strip is drawn through the skelping die 1, is then further heated internally and externally by a stream of gas from a. pipe 17, and then welded by a pressure ring or like 8 having a slightly tapered bore, the skelp being guided and supported by a tongue 11 loosely mounted on a vertical pivot 13 and preferably extending right through the die and pressure ring. The tongue may consist of a hollow cylinder with a rounded end 11<d>, external tapered portions 11<b>, 11<c>, one or more annular or part annular grooves 12 and a slotted under part to enable the tongs to be inserted through the tongue and die. The die may also be slotted for this purpose. The pivot 13, Fig. 3, is carried by a lever 14 pivoted on a removable pin 16 so that the tongue may be raised for insertion of the tongs. In a modification the corresponding pivot 21, Fig. 7, projects through the die, and rings 22, 23 are provided respectively on the tongue and die, to lift them out of the housing 2. The die and pressure ring are retained in the housing 2 at a fixed distance apart by engaging slots 6, 9 in a pair of gates 3, which are raised by handles 5 on pivots 4 to permit removal of the die and pressure ring on withdrawal of the pin 16. The pressure ring is seated in a slot in the base of the housing. The gas pipe 17 is clamped to one of the gates so that it may be brought down into correct position for directing the gas on to the edges of the skelp and into the groove 12. The groove may also be provided with a hole 12<a> and the edge of the die cut away at 1<b>. A water spray tube may be fixed to the other gate to cool the pressure ring and die, the water supply being preferably automatically controlled by the action of the gate. According to the Provisional Specification, the supply of gas may be turned on and off automatically bv the movement of the gate or tongues or by the pressure put on the bell or pressure ring.

A load 14, e.g. a chronopotentiometer, is supplied with constant current from input terminals 10, 11 by way of a regulating transistor 12 controlled by an error signal derived from an amplifier 22 and a current sensing circuit 21 which has a pair of parallel connected branches; the first branch includes a selector switch 36 associated with resistors 32, 33, 34, 35 for selecting one of a plurality of maximum load currents; the second branch includes a variable voltage source, constituted by a battery 25 and a potentiometer 24, and resistors 28 and 29 connected as shown, the signal at junction 31 between resistors 28, 29 being an error signal which is applied to the input of amplifier 22 which controls transistor 12 in a manner to maintain the error signal at zero. A desired load current, having any value from zero to a maximum determined by the setting of switch 36, may be selected by adjustment of the variable voltage source 24, 25, and this desired current is maintained constant by the action of the circuit 21, the amplifier 22 and the regulating transistor 12. To compensate for leakage current through the transistor 12, the transistor is arranged in a bridge circuit together with resistors 39, 41 and 42, the supply 10, 11 being connected across one diagonal of the bridge and the load being taken across the other diagonal.
