Filed: 1927-10-24
Abstract: 279,507. British Thomson-Houston Co., Ltd., (Assignees of Price, D. R., and Boxman, F. H.). Oct. 25, 1926, [Convention date]. Phaze differenees, measuring.-The stationary coil system of a synchroscope comprises four coils, 10 - - 13, of which the coils 10, 11 are connected to one of the systems 14 and the coils 12, 13 are connected to the other system 14a to be synchronized with the system 14. The coils 10, 11 are connected in parallel a resistance 17 being connected in series with the coil 11 and a reactance 16 in series with the coil 10 so as to produce a difference in phase between their currents. The coils 10, 11 are set at right-angles to one another, so that a rotating field is produced corresponding to the phase angle and frequency of the system 14. The oils 12, 13 are connected in series with one another and with a resistance 17<a> and magnetize a shift 15 provided with bent arms 18, 19 terminating in light magnetic vanes 20, 21 which are arranged to rotate within the influence of the rotating fied set up by the coils 10, 11. The vanes 20, 2. are polarized by the coils 12, 13 in accordance with the frequency and phase angle of the system 14<a>. If the frequencies of the systems 14, 4<a> differ, the vanes 20, 21 and spindle 15 carrying i pointer 24 rotate in one direction or the other according to which system has the higher frequency. When the frequencies are identical, the pointer 24 takes up a position in accordance with the phase difference, zero being. indicated by a mark 26. The stationary coil structure is assembled around a tube 28, through which the shaft 15 passes, and is supported at its centre by arms 29 situated between the paths of the upper and lower vanes 20, 21 so as not to interfere with their rotation.

Title: Automatic telecommunication switching system
IPC: H04Q3/00
Filed: 1966-06-24
Abstract: 1,133,435. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 24 June, 1966 [29 June, 1965], No. 28285/66. Heading H4K. Calling subscribers' identities, determined by transmitting a signal backwards over the switch train to the calling subscriber so as to singularize the subscriber to an identifier circuit, are transmitted to a distant recording centre over a path which is not the speech path. Used for billing local calls at a centre distant from the exchange the identification system employs a circuit IC which in response to a 20 kc. signal from the line circuit delivers the four calling party digits in 2 out-of 5 codes to store and forward circuits TC. If the codes check, they are transmitted to the distant centre as 2 out-of 5 tones over paths M1 or M2. When a metering function is required for a local call, the trunk between line finder 2LF and primary selector PS which has been seized by the calling subscriber must be connected to a store and forward circuit TC1 or TC2. To this end the register serving the call connects earth to a start lead ST. The 360 trunks are divided into ten groups of 36, each of which groups is served by two sets of six relays, one from each of which sets operates to a start lead ST so as to lock out all other start leads and extend the trunk to the group outlet. Of the ten such group outlets a second lock-out circuit ensures that of the trunks extended so far one may be connected to a store and forward circuit TC1 while another may be concurrently connected to circuit TC2. A further lock-out circuit ensures that if TC1 is connected to identifier IC then TC2 is not, and vice versa. When a trunk is connected to a store and forward circuit allotted for use, a generator G is connected to feed 20 kcs. back to the associated line circuit to elicit the required digits. The store and forward circuit is released when the distant billing recorder acknowledges receipt. For trunk calls, a register R selects a store and forward circuit TC3-TC5 over a connector TCS, the wanted identity being sent over the register and the outgoing trunk.

Title: Method of testing graphite
Inventor: BROCKLEHURST JAMES ERNEST
IPC: G01N17/00
Filed: 1962-07-26
Abstract: Polycrystalline graphite is exposed to bromine vapour, whereby dimensional changes take place.  These changes are correlated with dimensional changes resulting from neutron irradiation and can therefore be used to determine irradiation stability of the graphite.ALSO:Polycrystalline graphite is tested for dimensional stability under neutron irradiation by exposing a sample to bromine vapour, performing measurements to determine the bulk dimensional change as a function of absorbed bromine and deducing the extent to which changes in crystal structure (e.g. as produced by neutron irradiation) are reflected in the bulk material.  Test specimens cut either parallel or perpendicular to the grain of the graphite may be suspended from a calibrated quartz spring in a glass vacuum apparatus having controllable communication with a bulb containing liquid bromine at room temperature and specimen length and weight changes followed with a cathetometer.  Details of the necessary calculations, and typical graphs are given.

[Class 135.] In electric-motor valve operating arrangements of the kind set forth in Specifications 233,760, 307,445, [both in Class 135, Valves &c.), and 344,013, in cases where it is desired to operate a single valve with its attached byepass valve, or a number of such valves simultaneously, from any one of several different stations, the controller switches are fitted at the several stations, with or without a master controller switch, and are interconnected, each controller being provided with " safety " contacts which are "closed" in any of the valve-opening positions and " open " in a valve-closing position the motor-operation contacts of any controller, which are made or closed by movement of a controller to a valveopening position, are also connected to the mains in series with the "safety" contacts of the other controllers so that predominance is given to the " closing" position of any controller switch, whereby the valve or valves cannot be opened from any of the stations if one of the controller switches, or the master controller, is set to the " closed " position. Arrangements are shown with two and three controller switches for a single valve, or valves with byepasses opened and closed in a prescribed sequence. In the arrangement shown in Fig. 1 for a single valve, operated by a motor M, two controller switches K<1>, K<2> are employed, L and L<2> indicating the supply mains and o<1>, c<1> the " open " and " closed " limit switches operated by the valve member. Each controller has two rigidly-connected moving contact segments k, k<x>, " close " and " open " contacts k<c> and k<O>, oppositely-disposed contacts a<3>, a<4>, and interlock contacts a<1>, a<2>. When either controller is moved clockwise to a " close " position the segment k<x> of that controller leaves the contacts a<1> a<2> so that a gap is provided in the combined circuit which renders inoperative any opening movement of the other controller ; since, however, the closing contact a<4> of each controller is always connected to the main L<2>, the clockwise closing movement of either controller is operative to close the valve whatever the position of the other controller. Fig. 5 shows an arrangement for two valves and their byepasses with their motors M, and solenoids S, E, as in the prior Specifications referred to above, and with two controllers K<1>, K<2> and a master controller K<m>. When the master controller is moved to the " closed " position the contacts k<20>, k<30>, k<4O> are connected to the main L<2> and the contact k<5O> and lead 20 disconnected from the main. In this position the valves are all closed and the controllers, K<1>, K<2> disconnected from the mains L, L<2> and rendered inoperative.
