Title: Improvements in or relating to the supply and control systems of air blast circuit breakers
IPC: F23K3/10
Filed: 1955-06-01
Abstract: 781,120. Air-blast switches. ETABLISSEMENTS MERLIN & GERIN SOC. ANON. June 1, 1955 [June 1, 1954], No. 15723/55. Class 38 (5). In a remote control arrangement for an air-blast circuit-breaker having its blast valve 22 adjacent to the arcing chambers 17, 19 and controlled by hydraulic means, an air valve controlling the operation of an isolating switch is actuated by compressed air derived downstream of the blast valve 22. The blast valve 22 is opened on the opening of a relay valve 20 by a piston 43 when liquid in a cylinder 35 and pipes 37, 38 and 41a is moved by a piston 34 on the application of compressed air to a piston 29 generally as described in Specification 667,724. When the valve 22 is opened, compressed air is supplied to a cylinder 50 to move a piston 51. Piston 51 moves a piston 52 to cause movement of liquid in a cylinder 53, pipes 55, 40 and 59 so that a piston 61 is moved to open a valve 63. This admits compressed air from the cylinder 64 to a pipe 66 supplying the isolating switch operating mechanism (not shown). Reference has been directed by the Comptroller to Specification 667,724.

Stoppers, making. - Relates to apparatus for forming and inserting the protective seal in the packing- disc of a closuring capsule. The type of capsule is shown in Figs. 13 and 14, in which the seal s has inturned edges which are pressed into the cork disc b fitted in the capsule a. The machine has three intermittently rotating tables 30, 34, and 36, Figs. 1 and 2, which are geared together, and the forming and fixing dies are carried bv arms rigidly connected to a central column 70, which is vertically reciprocated by cam mechanism. The capsules with the packing discs in position are fed down a shoot 46 to a feed dial 28 and thence into pockets in the table 30, by which they are carried forwards over the table 34. At this position a plunger 54 descends with the column 70 and pushes the capsule into a pocket 52 in the table 34 which carries it forwards under a tubular die rotated by gearing 126, 122, 118, &c. The die descends with the column 70 and cuts a circular groove in the packing disc, the disc and capsule being held stationary by a presser-foot surrounding the die. The capsule is then carried forwards until it is brought under the table 36, where a seal, previously formed, is forced down by a plunger 160 so that its flanged edge enters the groove cut in the packing-disc. The capsule is carried forwards under a plunger 262, which presses the seal into position. The completed seal is ejected from the pocket in the table 34 by a cam device and is delivered by a spring detent into a discharge shoot 66. The seals are formed from a strip of metal s', Fig. 1, which is fed by rolls under the table 36 and above a punching- apparatus 192, Fig. 2. The punch is raised by a cam-actuated lever 194 and cuts out a disc which is flanged by being forced upwards into a tubular die carried by the table 36. The completed seal is carried around by the table to the position where it is placed in the grooved packing-disc by the descent of the plunger 160.

Title: Apparatus for investigating the proportion of a particular substance present in a sample
IPC: G01N21/31
Filed: 1964-04-17
Abstract: 1,074,472. Photo-electric concentration measurement. S.D. SMITH. April 14, 1965 [April 17, 1964], No.16011/64. Heading G1A. In a method of determining the concentration of constituents of a sample of gas, liquid, or solid by the degree of absorption of radiation within a particular absorption band; the sample is irradiated by radiation within a narrow wavelength range which only includes an absorption band of the particular substance under investigation and no absorption bands of any other constituents of the sample. Such radiation is passed by means of a chopper either intermittently through the test sample alone or alternately through the test sample and a reference substance which does not have absorption bands within the chosen wavelength range. In each case the A. C. signal produced, which is amplified by an amplifier tuned to the chopping frequency, has an amplitude proportional to the absorption. In the latter case the two beams can be equalized before introduction of the sample, or after an introduction retroactive feedback from the amplifier output may control a slot in the reference path to equalize the beams. The narrow wavelength range of radiation may be achieved by an interference filter or by the use of two such filters tuned by inclining them to one another. Also the non transmitting portion of the chopper may be replaced by a cell containing the particular sample constituent under investigation, the radiation directed through or still being within the narrow wavelength range. In the described embodiment the concentration of carbon dioxide in an air sample is measured using infrared radiation and an indium-antimony detector.

Title: Intercommunication telephone set
Inventor: GUNSON GEORGE RONALD
IPC: H04M9/00
Filed: 1967-04-07
Abstract: 1,149,118. Intercommunication systems. ERICSSON TELEPHONES Ltd 16 Feb. 1968 [7 April, 1967], No. 16153/67. Heading H4K. In an intercommunication system in which calls are set up over the home line of the called party, the effects of crosstalk are prevented by inserting a diode in series with the calling party's permanent magnet type receiver until such time as the called party replies. When station A calls station B by lifting his handset (thus operating CS1 and CS2) and actuating cb and hence OPC1 (but not OPC2), CO1 and CO2, negative battery n is extended to B's home line b. At this time diode MR which is connected in series with receiver R is non conductive since there is an open circuit condition and consequently it prevents any crosstalk that may be occurring on the b wire from affecting the receiver. When B replies (CS1, CS2 operated) the diode becomes conductive so that speech signals from B can now influence the receiver, crosstalk being no longer present due to the removal of the open circuit condition. In an alternative embodiment, contacts OPC1 and OPC2 are monostable so that brief operation thereof causes ringing current to be applied over r to the called party and ringing " tone " (produced by the fluctuating voltage developed in r during the operation of B's buzzer BZ) to be applied via the short-circuited diode to the receiver.

Title: Improvements in or relating to telephone systems
IPC: H04Q1/32
Filed: 1923-06-21
Abstract: 202,963. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Simmons, G. H.). Aug. 25, 1922, [Convention date]. Automatic exchange systems. - In a system using six-figure numbers but comprising exchanges not fully developed, a digit absorber designed to suppress one. or two digits according to the path over which it is seized is included in the switching chain to 1000-line and 100-line exchanges. Fig. 1 shows a system including two 100-line and two 1000-line exchanges selectable by a second group selector F<1>. The digit absorber DDA associated with the selector F<1> suppresses two digits or one according to whether connection to it is made over the first or third level of the first selector E as determined by the first digit in the number. If the subscriber A wants subscriber A in a 1000-line exchange, he first dials the digit 3. Selector E, Fig. 2, in the usual manner connects the line over its third level to the line relay 82 of the digit absorber DDA and also connects a grounded wiper 42. to the terminal 76 to complete a circuit for relay 84, which locks itself to the release conductor and energizes slow-release relay 87. On the first impulse of the second digit, relay 86 energizes, locks itself to the release conductor and opens the initial circuit and closes a point in a. holding circuit for relay 87, which remains energized while receiving impulses from armature 88 as the line relay operates, but, at the end of the digit, falls back and energizes the switching relay 81 which disconnests the line relay and extends the calling line to the selector F<1>. The remaining digits operate the selectors F<1>, H<1> and connector I<3> in the usual manner. If the wanted number is in a 100-line exchange, the digit absorber is seized over the first level of the selector E, in which case the terminal 76 is not grounded and relay 64 is not energized, so that relay 82 energies slow relay 85. At the first impulse of the second digit, relay 84 energizes, locks itself to the release conductor, opens the initial and completes a new circuit for relay 85, which is held by impulses from the line relay armature 88. At the end of the second digit, relay 85 falls back and energizes relay 87. The digit absorber is now in the same state as when it was seized over the other level, so that the end of the third digit will extend the call to the exchange selector F', the remaining digits completing the connection.
