Abstract: 485,843. Forced-flow steam boilers. WEIR, Ltd., G. & J., and HILLIER, H. Nov. 22, 1937, No. 32060. [Class 123 (ii)] [Also in Group XXIX] A non-return discharge valve for use with reciprocating or centrifugal pumps operating with boiling water, particularly circulating pumps employed in forced circulation steam boiler installations is so arranged that closure or partial closure of the non- return valve causes the opening of a connection through which cold water is delivered into the suction side of the pump. In the form shown in the Figure, a lift non-return valve M is guided by a spindle N working in a socket supported from the valve seat by spider arms. A cylindrical extension on the back of the valve member serves as a dashpot and encloses a loading spring U. Cold water supply and delivery passages R, S are adapted to be connected when the non-return valve is closed by a groove Z in the guide spindle and passages T in two of the spider arms. In a modification, the guide spindle of the non-return valve extends into a second valve chamber where it is fitted with a slide valve adapted to control the cold water supply.

Patent GB-397823-A (GB)
Title: Improvements in and relating to circuits for relays in alternating current systems
IPC: H02H3/00
Filed: 1931-11-23
Abstract: 397,823. Protective arrangements ; e 1 e ctromagnetic relays. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Meyer Akt.- Ges., P. ; 5, Lynarstrasse, Berlin.) Nov. 23, 1931, No. 32430. Convention date, Nov. 22, 1930. Void [Published under Sect. 91 of the Acts]. [Class 38 (v).] A protective relay 5, Fig. 1, is operated by the anode current of a valve 3 when the potential at the secondary 2 of a line current transformer exceeds that of a battery 4 by a sufficient amount. In Fig. 3, condensers 9, 19 give opposite potentials to the grid of a valve 3, proportional to currents at J1, J2, so that a relay 5 is operated when the ratio of the currents is excessive. The relay may be arranged to operate when the ratio of the difference to the sum of the currents is excessive, or, if the condenser 19 is given a voltage proportional to the voltage of the circuit when the impedance of a circuit is low. In a modification the grid of the valve is made positive to operate the relay, only when a reversal of current takes place. If, in the arrangement shown in Fig. 3, a resistance is placed in series with the rectifier 8, or if a potential divider or regulating transformer operated at uniform speed by a motor is placed in parallel with the secondary of the transformer 1, the relay may be given impedance time characteristics. In a modification a resonant circuit is used to obtain a time feature. In Fig. 10, the time element is introduced in the circuit of the voltage transformer 11. Upon operation of an initiating relay a switch 29 is moved to the left so that a potential proportional to that of the line is applied to a resistance 21 and the relay has a logarithmic time-impedance characteristic. In Fig. 11 an arrangement is shown in which the grid of the valve 3 is subjected to a voltage # sin # - #J, where # is a voltage proportional to that of a line which is displaced in phase by an angle # from a current J to which the voltage #J is proportional, a resistance 25<11> being provided, so that the relay 5 has a time reactance characteristic. The cores of the transformers may be constricted at suitable parts to vary the characteristics of the relay. In Fig. 15, the circuit of the relay 5 is closed by a switch operated by a coil 36, when the ratio of voltages proportional to the voltage and current in a line is below a certain value.

Abstract: 927,484. Two-part couplings. AMP Inc. Oct. 12, 1960 [Oct. 26, 1959], No. 32511/61. Divided out of 927,481. Class 38 (1). In a modular circuit system according to Specification 927,481 wherein self-contained units 2 carrying various components can be plugged into a framework consisting of parallel, vertical insulating plates 6 secured to a base plate 4 and divided into cells by separator plates 64, the side walls of each unit 2 are formed with grooves 22 containing channel-shaped, sheet metal contacts 24 retained therein by lugs 30 at one end bent over the wall of the unit and lateral lugs (not shown) at the other end which engage notches 28 in the side walls of the channels. In the operative position of the unit, the contacts 24 engage blade contacts 38 fixed to the plates 6 by bending over integral lugs 40 and having further lugs 56, 62 which pass through the plates 6 and 4 and are soldered at 60 to printed conductors such as 10 carried thereby. The blades 38, as shown, are embraced by channel-shaped members 46 attached thereto at 48 and having outwardly bowed portions 50 which resiliently engage the contacts 24. Alternatively the latter contacts may be provided with inwardly bowed portions 54, Fig. 12, formed in the side walls of the channels after severing them from the bases at spaced points. These contacts engage simple blades from which the members 46 have been omitted. Correct insertion of the units 2 is ensured by ribs 78 and recesses 76 thereon which engage grooves 74<SP>1</SP> and ribs 74 on the separator plates 64. Grooves 33 between the grooves 22 increase the leakage path between contacts 24. Specifications 866,528, 927,483 and 927,485 are also referred to.

Title: Improvements in and relating to transformer circuits
IPC: H01F29/04
Filed: 1945-12-03
Abstract: 626,126. Transformers; phase changing. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 3, 1945, No. 32577. Convention date, Dec. 4, 1944. [Class 38 (ii)] A continuous change of phase of a polyphase voltage through 360 degrees is obtained by tap changes on mesh-connected windings associated with a change of line connections from one winding junction to another in turn. Fig. 1 shows transformer windings 1 ... 6 in which voltages are induced in phase relations indicated by the arrangement of the windings in the Figure. These are connected in a closed polygon by direct connections 9 ... 11 and by connections 12 ... 14 through contacts 7, 8 associated with inductances 12 ... 14 and antiarcing switches 16. The line conductors 23 ... 25 are-connected to rotary switch contacts 20 ... 22. The connections established in Fig. 1 produce the situation shown in Fig. 2, in which the arrows indicate the resulting polyphase vector system of voltages. Movement of the tap-changing contacts in a clockwise direction progressively shifts this vector system clockwise through 60 degrees as indicated in Fig. 3; when this change has been completed the switch contacts 20 ... 22 are moved through 60 degrees, whereupon anticlockwise rotation of the taps causes a further 60 degrees clockwise rotation of the vector system. The next 60 degrees is obtained after a further shift of the taps and so on to complete the 360 degrees phase shift. Reversal of the sequence described produces an anticlockwise movement of the vector system. The length of the voltage vectors remains substantially constant throughout. A modification enabling this vector length to be varied and the polyphase voltages varied as well as shifted in phase is also described, wherein the connections 12 ... 13 are made to the mid-points of two inductances connected across the respective pairs of tap-changing contacts associated with each transformer winding.
