Title: An improved method of and means for the magnification of small electric currents
IPC: H04L15/30
Filed: 1925-07-10
Abstract: 258,970. Muirhead &. Co., Ltd., and Davies, B. July 10, 1925. Systems using non-contact-making relays.- Small currents, such as those received from submarine cables, are amplified by causing them to excite a dynamo of which the magnetic circuit is composed of material of high permeability such as permalloy or the material known by the Registered Trade Mark " Mumetal," the amplified current being taken off from the armature. In practice, a cascade of such amplifiers is employed and the field circuits may be tuned by shunt or series variable condensers 9. The condensers may be shunted by variable resistances. The armatures are preferably mounted on a common spindle. The dynamo in addition to the field system, 11, 12 14 which is excited by the signals is provided with a second field magnet 15, 16, excited by a local source of alternating current. To increase the flux density the usual air gap may be replaced by an oil gap, the poles being embraced by non-magnetic material and bored out to act as a bearing in which the armature rotates as a spindle. A retroactive action which has the effect of altering a signal from the shape shown in full lines, Fig. 5. to that shown in dotted lines may be introduced by coupling the input and output circuits by means of a transformer or a condenser, or as shown by providing a supplementary field winding in the output circuit. The retroactive action is regulated by the variable resistance 20.

Abstract: 516,233. Rolling screw threads. PLAGEMANN, W. June 18, 1938 No. 18174. Convention date, June 19, 1937. [Class 83 (iv] A blank to be screw threaded is placed between grooved rolls 2, 3 on top of a rockable' work support 61 and the rolls are moved towards each other to form the thread gradually. The roll 3 is adjusted axially by sliding its housing 26 on the bedplate 55 and for threading conical blanks, the bedplate 55 is adjusted angularly about pivot 58 by adjusting screws 59, flexible universal joints 18, 19 allowing this adjustment. Exact adjustment of the threads of roll 3 in relation to roll 2 is obtained by uncoupling 20, turning round the worm shafts 7-11-5, and recoupling 20. The roll,driving motor 15 is then switched on, rotating the rolls through belt 14, gears 12, worms 9 or 11 to each roll shaft. At the same time the roll 2 is progressively pressed into the blank by hydraulic cylinders 36 37 supplied by a valve chest 65 with hand control 68, the oil pressure being gradually increased. The approach of the roll 2 to the blank towards the fixed roll 3 (pass adjustment) is recorded on a dial 75 operated by an arm 83 coupled to linkwork 76, 80, 84 on both roll shafts. When the roll 2 has advanced far enough electrical contacts 87, 88 are closed, so completing circuit to a solenoid 70, Fig. 3, which operates valve 65 to stop the supply of oil to the roll-advancing cylinders 36, 37. A contact screw 88 is set to adjust the point of this interruption in accordance with the inner diameter of the desired threads. The blank support 61 is freely movable transversely and parallel to the blank axis and is low so that the blank axis is below the line joining the roll axes. For tubular blanks a pin 63, Fig. 5, on the support 61 receives the tube. The oil pressure in the roll advancing cylinders 37 is measured by gauge 45 and when excessive is interrupted by a spring relief device comprising a piston 47 closing contacts 48 to operate the same solenoid 70, Fig. 3, and stop the oil supply to cylinders 36, 37. On stopping hydraulic pressure, a spring 42 and pull bolt 34' withdraw tHe roll 2 from the work. A spring 30 permits roll to yield by moving axially.
