Title: Improvements in and relating to synchronous dynamo electric machines and synchronous electric motors
IPC: H02K19/36
Filed: 1928-06-26
Abstract: 315,085. English Electric Co., Ltd., and Schroeder, G. June 26, 1928. Pole-pieces.-Synchronous salient-pole dynamos or motors are fitted with adjustable magnetic shunts located in grooves formed in adjacent pole sides facing each other whereby the shape of the saturation curve may be adjusted within desired limits. In the form shown, the shunt consists of a packet of laminations a made entirely or in part of magnetic material, and provided with openings c to prevent interference with the machine ventilation. The shunts may be placed at any desired distance from the rotor body by suitably spacing the sections of the field coils and air gaps may be formed in them in the direction of the leakage flux. In highspeed machines, the bridges may be secured to the rotor by radial bolts, for example, by extending the bolts of the wedge-shaped supports which hold the field coils in place. The Provisional Specification states that the shunts may be placed between the outside surfaces of the field winding or may butt against the poles themselves between suitably spaced coil sections; also that they may be placed at the ends of the poles instead of between them.

Title: Improvements in or relating to the manufacture of cylinder liners and the like
IPC: C21D9/08
Filed: 1937-07-03
Abstract: 486,172. Heat - treating; alloys. ANDREWS GRINDING CO., Ltd., H., and ANDREWS, H. July 3, 1937, No. 18548. [Classes 72 and 82 (i)] [Also in Group XXII] In a method of correct ing ovality in cylinder liners, sleeves and like cylindrical articles which have become distorted in hardening or machining, one or more expanders or cramps which over-correct any ovality or distortion are applied to the liner or sleeve, and the liner &c. is heat-treated or tempered with the expanders or cramps in position. If the liner &c. is made of a metal which it is not desired to harden or of which the structure is not to be modified by heat treatment, the liner &c. after the application of the expanders &c. is heated to a temperature up to 450‹ C. which is sufficiently high to relieve stresses in the metal but is not high enough to modify its structure. An example of such a metal is an austenitic cast iron alloy containing 14-15 per cent of nickel, 5-8 of copper and 1À5- 3À0 of chromium, The expander shown in the Figure consists of a pair of blocks b, c having arcuate outer faces of a radius approximately equal to that of the liner and a stud d having right-hand and left-hand screw threads on opposite ends engaging screw-threaded bores in the blocks b, c. The centre of the stud is provided with a nut e for engagement by a spanner. Where a cylinder liner is distorted throughout its length two studs d may be provided which fit into bores in two arcuate bars of the same length as the liner. Instead of an expander an external cramp engaging the outside of the liner at two points and applied to the major axis of the oval liner may be used. The process may be applied to liners which have been quenched from 840‹ C. and tempered at 340-350‹ C.

Title: Improvements in combined electric switches and voltage regulators
IPC: H02P9/24
Filed: 1927-07-15
Abstract: 283,912. Bosch Akt.-Ges., R. Jan. 20, 1927, [Convention date]. Supplying consuming devices from variablespeed generators; regulation, automatic.-A combined electromagnetic cut-out and voltage regulator for vehicle lighting sets has an armature which after the closing of the cut-out contacts, can move freely to operate the regulator as shown in the Figure an armature 5 is carried by a blade spring 6 secured to the magnetic frame 1 on which is mounted a core 2 with shunt and series windings 4, 3. When in its unattracted position the limb 7 of the armature bears against the end of blade spring 17 carrying a contact 18 which is thus held away from a cooperating fixed contact 10. On attraction of the armature due to a sufficient voltage in the dynamo 19 the initial movement of the armature allows contacts 10, 18 to come into engagement, the springiness of the blade 17 assisting this movement. The charging circuit to the battery 21 is thus completed. After this initial movement the armature can continue its movement independently of the blade 17 and the projection 8 engages a push rod 14 so transferring the voltage regulating contact 13 from the contact 11 to the contact 16. This has the effect of first switching in the resistance 22 in series with the field winding 21 and finally of short-circuiting this winding the apparatus thus functioning as a vibrating regulator. The controlled circuits may be modified so that movement of the armature cuts in and out further excitation windings or alternatively the regulator contacts may be replaced by a carbon resistance acted upon with varying pressure by the movement of the armature.

Abstract: 1,023,873. Magnetic storage apparatus. RADIO CORPORATION OF AMERICA. May 13, 1963 [June 11, 1962 (2)], No. 18869/63. Heading H3B. [Also in Division H1] A sheet of ferrite material 20 (Fig. 6) having its two major surfaces parallel has at least one conductor 14 embedded in it so that an exposed surface of the conductor lies flush with one of the major surfaces of the sheet. The ferrite is in the green state and may be bonded under pressure and heat with other sheets of green ferrite 22, 24, the latter of which incorporates an embedded conductor 26, the building material being then burnt out and the sheets being then raised to sintering temperature and subsequently air quenched or annealed in nitrogen. The conductor 26 may include portions extending parallel with each of the three conductors 14. A large number of conductors and memory locations may be provided in each composite sheet 30. The conductors may be of palladium, rhenium, rhodium, platinum or alloys thereof and the ferrite of zinc, magnesium and manganese oxides with an organic binder and a methyl ethyl ketone solvent. The conductors may be deposited on a beryllium copper sheet 10 (Fig. 4, not shown) by a photo-resist process and covered with ferrite slurry, the copper sheet 10 being subsequently etched away. The ferrite may be spread by a doctor blade, a callendar roll or a spray gun. Alternatively a paste of powdered conducting material mixed with petroleum grease may be deposited through a stencil 40 (Fig. 9, not shown) on to a substrate 46 to form conductors 44 which are subsequently covered with a layer of ferrite slurry which is dried and peeled off the substrate bringing with it the conductors which are wider at their inner surfaces. Some of the petroleum grease is dissolved out of the conductors so that shrinkage of the ferrite occurring when the composite member is sintered after suitable sheets have been bonded under pressure, compacts the conductive powder.
