Abstract: 440,370. Induction motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. June 29, 1934, No. 19281. Convention date, July 1, 1933. [Class 35] In a system comprising an asynchronous motor with an automatically regulated resistance in the secondary circuit and a three-phase commutator machine cascaded with the motor, the angle between the commutator voltage and the network voltage is so regulated that below a predetermined load limit the power factor of the motor is improved and its speed slightly increased, and above this limit the phase-displacing effect of the commutator machine is increased, and its speed-increasing effect diminished. For this purpose the commutator machine h may be a frequencychanger without stator and a single armature winding fed through slip-rings from a transformer t. The commutator brushes are mounted on a rocker adapted to be moved by a motor m, which also regulates a liquid resistance W in the secondary circuit of the main motor V and is fed from the network through a transformer t<1>. If the machine h has a stator the transformer t may be replaced by an induction regulator coupled with the motor m.

Title: Improvement in blind-stitch sewing machine
IPC: D05B85/06
Filed: 1943-11-18
Abstract: 571,094. Sewing-machines. LEWIS INVISIBLE STITCH MACHINE CO. Nov. 18, 1943, No. 19305. Convention date, July 29. [Class 112] In a blind-stitch sewing-machine the worksupport may be moved away from the presserfoot independently of the work-bender. Additionally, a single manual means may be operated to move the work-support and the workbender away from the presser-foot to provide an opening for the insertion or removal of the work. The invention is applicable to either chain-stitch or look-stitch machines. Worksupporting platens 16, 17, Figs. 4 and 10, are independently and resiliently supported. The platen 17 is supported on a lever 18, pivoted at 19, and held up by a light spring 21. The platens are lowered to the position shown in Fig. 10 by operation of a knee-press which, through levers, causes the rotation of a shaft 26 by rotating a shaft 30 and lowering a link 32. A work-bender 34 is mounted on the end of a shaft 35, journalled in bearings 36, 37 in a cradle 38. The latter is pivotable about pins 39, 40, Fig. 4. The cradle is held in operative position by a heavy spring 43. The workbender is oscillated through rotation of the shaft 35 by means of an eccentric 61, Fig. 7, acting on levers 63, 64 and connecting-rod 68, which is pivoted to one end of a lever 69, The latter is pivoted between its ends on a shaft 70, Fig. 8, that is formed integral with, and eccentric with respect to, a shaft 71. Fig. 8 shows the connection to the bender 34 which is in its upper position. A link 73, connecting the lever 69 and the crank-arm 74, allows the shaft 35 to move substantially vertically, when it is necessary for the work-bender to yield. The depth of penetration of the needle is adjusted by adjustment of the cradle 38, to limit the movement of the cradle under the action of the spring 43. The adjustment is secured by rotation of a knob 60<1> to rotate a screw 60 and move levers 57<1>, 55 and rod 52 to cause an arm 47, supporting the cradle 38, to rotate slightly. Manual retraction of the bender 34 is effected by rotating the shaft 71, and so shifting the pivot 70, by means of a gear 75 meshing with a gear 76 on a shaft 77. This is done, when the machine is stopped, by the operator pressing the knee-press to the fullest extent, a shoe 79, Fig. 11, engaging a stud 78 and rotating the gear 76 to cause the lowering of the pivot pin 70. A finger lever 85, Fig. 5, may be moved to the dotted position shown, causing a circular block 84 to move from one detent notch 86 to another 87, co-operating with a detent 88 on a spring-held disc 81. Rotation of 84 causes the shifting of the pivot 70 for the lever 69, affecting the vertical height reached by the work-bender, and thus the depth of penetration of the needle.

Title: Electro-magnetic, automatically-operated safety switch
IPC: H01H83/12
Filed: 1952-07-31
Abstract: 723,052. Protective cut-out arrangements; electrically-released switches. PEGURRI. G. July 31, 1952, No. 19349/52. Class 38 (5). A device for controlling the supply of current from a low voltage supply 17 through a transformer 18 to a high voltage circuit 19, such as that of a neon sign 20, comprises a manuallyoperable main switch 6 and an electrically-released switch having its coil 3 and contacts 7, 8 connected in series in the primary circuit of the transformer. In operation, the switch 6 is closed and a push button 5 is depressed to move an armature 10 against the bias of a spring 13 to close a contact 7 onto contact 8. This completes the primary circuit and the coil 3 is energized to retain the armature 10 when the push button 5 is released. Should the current flowing in the coil 3 be reduced due to an open circuit fault the armature is released and the contacts 7, 8 are opened to interrupt the supply to the transformer. If an overload occurs, the current in the coil 3 creates a magnetic field strong enough to move a catch 14 out of abutting engagement with the contact 8 which is then moved by a spring 15 away from the contact 7 to open the primary circuit. This de-energizes the coil 3 causing the release of the armature 10, so that it is necessary to reset both the armature and the contact 8 to restore the supply.

Abstract: 204,798. Edgcumbe, K., and Everett, E. I. July 14, 1922. Phase-differences and power-factors, measuring.- Relates to electric meters for indicating phase-difference, power-factor, synchronism, &c., of the kind in which a field produced by one or more current coils acts upon a rotatable iron member magnetized by one or more fixed coils. According to the invention, a system of currentcarrying coils produces a rotating field in which is located the moving member carrying segments magnetized by fixed pressure coils astatically connected and mounted in close relationship. In this way the circuits are rendered non-inductive, disturbance from external fields is eliminated, and the current in the pressure coils is substantially independent of frequency variations. As a power-factor meter for three-phase unbalanced loads, the current coils a, Fig. 2, are arranged with their magnetic axes in one plane and 120‹ apart, and the moving system, comprising a spindle b, Fig. 1, carrying soft-iron segments c 120‹ apart and parallel to the magnetic axes of the current coils, is magnetized by pressure coils d astatically arranged in close relationship and coaxial with the spindle. The current coils may be divided, each half being located opposite the other as shown in Fig. 3. With a balanced load the three. and six arrangements of current coils may be replaced by one and two respectively. For two-phase unbalanced loads, four current coils and two pairs of pressure coils are provided, the latter magnetizing segments located 90‹ apart. With a balanced load two of the current coils may be omitted, and this arrangement may be used on single-phase circuits, the pressure coils being energized by artificially displaced currents. The instruments may be used as phase or synchronism indicators or relays.
