Title: Improvements in and relating to mercury vapour rectifiers
IPC: H02M7/15
Filed: 1932-02-05
Abstract: 395,779. Rectifying alternating current. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Feb. 5, 1932, No. 3462. Convention date, Feb. 5, 1931. [Class 38 (ii).] In grid-regulated mercury-vapour rectifiers, the grids are normally negatively charged but are periodically subjected to a positive potential of short duration in order to render their respective anodes conducting, the positive potential being distributed to the grids by rotary contact apparatus having adjustable timing to enable the output voltage of the rectifier to be varied. Figs. 3 and 5 show alternative arrangements each comprising a polyphase rectifier 2, a supply transformer 1, load circuit 5, and a set of grids 4 connected to a source of negative potential and to a rotary distributer 8. In Fig. 3, the source of negative potential is shown as a battery 15, and in Fig. 5 negative bias is derived from a tapping on a resistance 18 in the circuit of the exciter anodes. In the first case, the source of positive potential supplied to the distributer 8 is shown as a battery 11, and in the second case, the positive potentials are derived by tapping the positive half waves from a transformer 17 associated with the distributer. In both cases the distributer is driven synchronously with the supply frequency by a motor 9, and grid current limiting resistances 6, 6a are provided. Protection against excess current and back-ignition may be provided by inserting an automatic switch 13 in the distributer circuit, the switch being adapted to open under fault conditions and interrupt the positive voltage impulses which normally render the rectifier operative. Angular displacement of the non-rotary part of the distributer for effecting voltage regulation may be effected by hand or automatically in response to output voltage, load current, or both.

Patent GB-666256-A (GB)
Title: Improvements in or relating to valve mechanisms
Inventor: BOWNS DESMOND EDWARD
IPC: G05D11/00
Filed: 1949-02-09
Abstract: 666,256. Fluid-actuated valves. ROLLS-ROYCE, Ltd. Feb. 7, 1950 [Feb. 9, 1949], No. 3530/49. Class 135. A valve for maintaining the flow of fluids through a plurality of pipes in a preselected ratio comprises at least three independent passages, a valve member in each passage controlling the flow therethrough to or from a common passage connected with each independent passage, a diaphragm connected to each valve member arranged to be subjected to the pressure in its associated passage, and means interconnecting the diaphragms so that each is subjected to an equal force in opposition to the pressure dependent on the fluid flow. As shown, a valve casing 14, Figs. 1, 2, having four independent inlet passages 10 ... 13 and a common outlet passage 15, houses in each inlet passage a valve member 21 connected by a link 20 to a diaphragm 16. The diaphragms form four sides of a box 14a and are connected at their bottom edges to a rigid plate 22 and at their top edges to a wall of the casing having an aperture closed by a flexible bellows 25 connected by a link 26 to a similar bellows 24 closing an aperture in a rigid chamber 23. The box 14a and the chamber 23 contain equal volumes of a deaerated liquid, e.g. paraffin. In operation, an increased flow in one inlet passage produces an increased pressure which acts on the associated diaphragm to deflect it inwards and move the valve connected thereto towards closure. The liquid in the box 14a being incompressible, the other three diaphragms deflect outwards to adjust their valves towards open position and so maintain identical flows in the four passages. Should an increase in temperature occur, liquid in the chamber 23 will expand to extend the bellows 24 and through the link 26 the bellows 25 to increase the volume of the box 14a. To reduce the space occupied by the liquid in the box 14a, rigid walls may be fitted within the box in spaced relationship to the diaphragms, the effect of temperature changes then becomes negligible, and the chamber 23, bellows 24, 25 and link 26 may be dispensed with. In a modification, instead of liquid in the box 14a, pulleys 28 (Fig. 3), connected by links 27 to each of the diaphragms 16 may be housed therein, an endless-belt 29 passing over fixed guide pulleys 30 interconnecting the pulleys 28. Instead of having four inlets and a common outlet the valve may have a common inlet and four outlets to disperse the flow equally therein or in a preselected ratio whence sluice gate elements 32, Fig, 3, are fitted. Spring-loaded byepass valves may be fitted between each independent passage and the common passage and operate on a predetermined pressure difference being reached to bye-pass the main valves.

Title: Carriers for braiding machines
IPC: D04C3/14
Filed: 1936-02-07
Abstract: 452,634. Braiding-machines. COOK, W. E., 129, Hart Boulevard, West New Brighton, Staten Island, New York, U.S.A. Feb. 7, 1936, No. 3781. [Class 74 (i)] A travelling yarncarrier for braiding- machines, of the type having a base provided with a vertical spindle on which the cop rotates, has an upright parallel to the spindle and provided with a vertically elongated opening through which the yarn runs with a general horizontal trend (but for substantially the entire height of the cop, with a vertical component of movement), to pass about a traveller slidable on the upright, and a lead-off eye adjacent the top of the upright, a collapsable yarn confining member extending between traveller and lead-off eye. Parallel to the cop spindle 14 are two rods 18, 19 upon which slides a traveller 25. These rods, with stops 20, 21, (so arranged as not to impede the motion of the traveller) form an elongated slot. The yarn may be led direct from the cop through the slot, but preferably a bight (e.g. 34) is taken round a guide rod 33 and round the cop itself, and the yarn then runs through the slot under the traveller and thence to a leadoff eye 23 through a guide consisting of a light helical spring 28, held on a guide rod 24, and serving to prevent ballooning of the yarn. The bight 34 reduces the variation in the angle at which the yarn approaches the traveller, and prevents it dropping down and forming excessive slack as it reaches the bottom of its vertical run on the cop. As the traveller approaches the upper limit of its movement the resistance of the spring 28 causes yarn to be drawn from the cop. A pivoted, spring actuated brake plate 31 is so shaped as to decrease the contact area between it and the cop as the diameter of the latter decreases, so as to reduce braking effect with torque. A threading device comprises a length of wire 37 Fig. 5, having fastened to it at each end a flexible strand 40, forming a closed loop. The threader is passed down through the lead-off eye 23 and spring 28, and beyond the traveller 25, the looped strand 40 is passed through the elongated slot in the upright 18-19, and the end of the yarn passed through this loop. The threader is then withdrawn whilst the operator holds the end of the yarn during the withdrawal, releasing it towards the end of the operation.

Title: Improvements relating to the control of fluid-flow in conduits connected in parallel
IPC: F16K11/04
Filed: 1940-03-02
Abstract: 577,132. Valves. WHITTLE, F. March 2, 1940, No. 3950. [Class 135] A valve device for controlling the rate of flow in a conduit in accordance with the rate of flow or pressure in a master conduit comprises a restriction D<2> in the conduit and downstream thereof a valve D<4> to control the rate of flow through the conduit operated by a pressure sensitive device, such as a diaphragm D<5> subject to the pressure in the master conduit E and the pressure in the controlled conduit between the restriction and the valve. In the form shown in the Fig. the pressure on the control conduit E varies with the flow in a conduit B. For this purpose a restriction B<2> is inserted in the conduit B and a second restrictor may be inserted in the aperture B<3> to cause a pressure-drop equal to or greater than that caused by the valve in its fully open position. In a modification the conduit E serves merely to transfer liquid from beneath the diaphragm D <5> to the chamber beneath a diaphragm C<5> actuating a valve C<4> controlling a second conduit C. In this form the quantity of liquid in the two diaphragm chambers is adjusted by a variable capacity chamber.
