Filed: 1951-09-18
Abstract: 700,036. Generators. AERO MATERIEL AKTIEBOLAG. Sept. 18, 1951, No. 21876/51. Class 35 A single or polyphase induction generator system whose output is of constant voltage and frequency irrespective of speed, comprises a master generator 1 supplying constant frequency exciting current to the stator 2 of a first induction generator, whose rotor 3 is driven by the same mover 7 as the rotor 4 of a second induction generator, the rotors being connected together in reverse phase rotation. The voltage generated in the rotor 3 of the first generator has a frequency equal to the sum of the excitation frequency from the master machine 1 and the frequency of rotation. This voltage is applied to the rotor 4 of the output generator in inverted phase sequence so that, since the rotor is driven at the same speed as the first machine, the frequency obtained is lowered again by an amount equal to the frequency of rotation and the output of stator 5 has a frequency equal to that of the master generator 1. Constant voltage is maintained by connecting the output of stator 5 to a compounding winding 9 on stator 2, a voltage regulator 10 also being used if required. In the form shown, the load 8 is connected to the stator 5 but in a modification it is coupled to the stator winding 2. It is stated that the amount and phase of back-coupling may be such that one machine acts as an inductance and the other as a capacitance.

Title: Improvements in or relating to electric switchgear
IPC: H02B1/00
Filed: 1930-07-22
Abstract: 354,039. Switchgear structures. METROPOLITAN ELECTRIC SUPPLY CO., Ltd., WILLIAMS, H. LLOYD-, and SWAN, L. J., 16, Stratford Place, Oxford Street, London. July 22, 1930, No. 22086. [Class 38 (v).] Switchgear comprises a cubicle in which a plurality of switches are mounted one above the other, and a bus-bar extends vertically down one side of the cubicle and is connected to corresponding terminals of the switches, the other terminals being connected to cables in a duct or space at the other side of the cubicle. A common bus-bar may extend between two cubicles arranged side by side. A pair of cubicles 1, 3 are mounted side by side and have outer spaces 7 and a central space in which ingoing and outgoing cables 15, 19 and the bus-bars 5 respectively are located. Main oil switches 9 .. 12 in the cubicles are connected through isolating switches 31 on one side with the bus-bars and through isolating switches 21 on the other side to the cables 15, 19, the isolating and main switches having the usual interlocks. Each main switch 9 .. 12 has a door hinged at 57, 59 to the framework for permitting access to the switches, and, when the latter are open, the live terminals 27 are covered by gravity shutters 43 pivoted at 45 to arms 47 which in turn are pivoted to spindles 53. In the normal position A the shutter 43 engages a pin 51 on the arm 47 and when lowered to the operative position serves to close a space formed between screens 41 in front of the live terminals, each shutter extending from front to rear of the cubicle to cover the, terminals of all three phases. The isolating switches are rotated about their spindles 23 from the vertical position to a horizontal position to close the circuit between the cable terminals 17 and main switch terminals 25 or between bus-bar terminals 27 and main switch terminals 35. In the latter position, latches 61, 63 on the shafts 23, 53, respectively, obstruct and prevent movement of the covers. When the handle 24 is to be operated to open an isolating switch, Fig. 4, a sliding bolt 65 is raised out of a notch 67 whereupon the shaft 23 can be rotated for isolation. The bolt 65 is then moved into a slot 71 in the boss of the now vertical latch 61, at the same time disengaging itself from notch 69 which allows the shaft 53 to rotate under the action of the shutter 43. Only when both isolating switches associated with a cover are moved to the open position can the cover be removed, the shutters 43 covering all the live terminals. The main switches can be vertically or (as shown) horizontally removable, a bolt in the switch frame ensuring correct positioning of the switch when being replaced. The cubicles may contain more than two switches, and a bus-bar 81 is provided to enable extra units to be added at the side or on top of the existing cubicles.

A ballast tamping machine constructed similarly to that described in Specification 666,534 is provided with shovels which are operated automatically in a direction transverselv of the railway track and displace ballast, previously disposed along the road bed on the outer sides of the track, into the cribs between the ties or sleepers, so that it can be tamped into position by the automatic tampers. The shovels are operated by compressed air, and timed to make an "in", or operating, stroke during an up stroke of the drophead upon which the tampers are mounted. A pair of shovels 80 is secured on a horizontal shaft 83 journalled in hangers 85 on a longitudinal frame beam 11, the arrangement being similar on both sides of the machine, and a rocking- arm 86 secured to the shaft 83 is pivotally connected to a stem 89 on a piston which is slidable within a cylinder 87. Compressed air from a cylinder 98 at the side of the machine is admitted through a pipe 98<SP>1</SP>, control valve 99, and pipe 108, to the cylinder 87 when the valve is actuated by a stud 110 on the drophead 16 striking and rocking an arm 106 during the upward stroke of the drophead. As shown in Fig. 6 the control valve comprises a casing enclosing a stem 102 carrying two valve members 100, 100a, one end of the stem being adjacent to a cam 105 at the end of a lever 103 which is normally held in a central position by two tensioned springs 107, the valve member 100 then being held on its seating by a spring 113, so that passage between pipes 98<SP>1</SP> and 108 is closed. During the down stroke of the drophead the stud 110 strikes the arm 106 and turns the lever 103 in a direction such that the cam 105 is inoperative and the valve members remain as shown. However, on the upward movement of the drophead, when the lever 103 is turned in the opposite direction, the cam 105 lifts the valve stem to admit air to the cylinder 87, and at the same time the exhaust from pipe 108 to part 109 is cut off by valve member 100a. The shovels each consist of a shoe 81 pivoted on an arm 82 by a pin 94 and normally held against an abutment 96 on the arm by a tensioned spring 95 connected between them.

Title: Improvements in and relating to the production of filaments, threads and the like bythe wet spinning process
IPC: D01D5/06
Filed: 1948-08-26
Abstract: <PICT:0653363/IV (a)/1> A process for the production of threads by wet spinning comprises extruding a fibre-forming solution, e.g. viscose, through a jet 2 into a coagulating bath 3 and withdrawing the thread upwards from the bath on to a rotating thread take-up device 6, which may be a thread-advancing reel, a pair of rollers over which the thread passes in helical turns, or a godet, the thread being led directly from the bath against the edge of a smooth annular guide 5 rotating at a peripheral speed greater than that of the thread take-up device 6.  The guide 5 may be formed as a cowl and screwed to the reel &c. or it may be formed integrally therewith.  In an example, the reel 6 was situated about 24 inches above the bath and had a diameter 1 1/2 inches more than that of the reel. The thread passing from the bath was observed to do so without greatly disturbing the surface and to take only a thin film of liquid with it.  An economy in the amount of sulphuric acid removed from the bath was obtained.  The thread may be stretched between the reel 6 and further take-up reels on which it is processed in known manner. Specifications 413,413, 413, 414, [Group IX], 474,973, 496,385 and 539,657 are referred to.
