Title: Improvement in electric motor
IPC: H02K17/04
Filed: 1951-07-10
Abstract: 704,626. Induction motors. HUTCHINS ELECTRIC CO., Inc. July 10, 1951 [Aug. 4, 1950], No. 16372/51. Class 35 A split-phase motor has two windings wound in the same slots, one being more powerful than the other so that a current of opposite phase is induced in the quadrature parts of the subordinate winding, thus producing the effect of a phase-split. The in-phase sections AA' and BB' of the main and subordinate windings respectively are in additive relationship but the quadrature sections A'A" and B'B" are wound in opposition. As a result, the currents in the quadrature sections are in opposite phase, thus producing a phase displacement AB between the two windings. During normal running, voltages are injected into the subordinate winding by transformer action from the main winding and by the rotor flux so that its total back-E.M.F. is equal to the applied voltage and it carries no current. If desired, however, the subordinate winding may be switched out during running. Specification 680,137 is referred to.

Title: Improvements in or relating to drill grinding jigs
IPC: B24B3/24
Filed: 1948-06-24
Abstract: 651,162. Grinding twist drills. READING, H. C. June 24, 1948, No. 16992. [Class 60] A drill-grinding jig provided with a drill guide 35, Fig. 5, pivotally mounted about an axis 30, Fig. 1, has means for adjusting the guide together with the axis towards and away from the grinding face 12 and means for adjusting the drill guide independently of the axis 30 in a direction having components along the drill axis and in a direction normal to and intersecting both the axis 30 and the drill axis. The drill guide is bolted to a slide 33 which can be locked in position on a slideway 32 integral with and inclined to an arm 28. The latter has two centres 24 which are received in conical depressions at the top of a column 22 forming part of a slide 21 adjustable along a rectilinear slideway 19. One of the centres 24 is in threaded-engagement with the arm 28 and may be adjusted by means of a nut 31, while both centres lie on the axis 30. The slideway 19 forms part of a table which can be angularly adjusted about a pivot 11 the axis of which is midway across the face 12 and tangential to it. The table is graduated at 16 to facilitate adjustment and provided with clamping means. The drill guide 35 is of V crosssection, Fig. 6, and supports a slide bar 50 on which are adjustably mounted a second guide 52 of similar shape to the guide 35 and a calibrated adjustable abutment 55 by which the drill may be fed along the guide. The drill is clamped on the guide by a lever 37 having a cam-faced portion 42 which is engaged by a nose 41 on a lever 38 provided. with a thumb-piece 40 and the drill is located angularly with respect to the guide by a platform 49. The faces of the drill guide are disposed at unequal angles to the vertical so that an increase in the size of drill produces a displacement of the drill axis towards the right as viewed in Fig. 6. The drill size also determines the position of the slides 21 and 33 along their slideways and each slide is set by placing the drill shank between two inclined abutments, one of which is supported by the slide and the other by the slideway. These adjustments may alternatively be made by the use of calibrated scales. When all of the adjustments have been effected to produce the correct relationship between the drill and the grinding face, the arm 28 is given a swinging movement by means of a handle 29 in order to produce a facet with the required clearance at the drill point. The base of the jig, which is mounted on a slide arranged to be traversed parallel to the grinding wheel axis, carries a diamond for trueing.

Abstract: 612,886. Control systems for welding arcs. FOSTER TRANSFORMERS & SWITCHGEAR, Ltd., BAGNALL, R. I., and JENNINGS, R. E. June 5, 1946, No. 17041. [Class 38 (iv)] To ensure a safe no-load voltage on an A.C. arc welding electrode a normally closed switch 2, 3 is held open by a coil 4 connected through rectifiers and a resistance 11 across the welding terminals. In this condition contacts 3, 9 connect the electrode 1 to a low voltage point on the potentiometer 11, 4. When the electrode contacts the work 7, the coil 4 is short-circuited and the connection 2, 3 established, the voltage drop in the impedance 5 preventing sufficient energization of the coil 4 to open those contacts so long as the arc is operative. When the arc breaks, the voltage on the electrode is limited by the action of the coil 4. Time delay may be associated with the opening and also with the closing of the contacts 2, 3.
