Title: Improvements in moderator core structures for nuclear reactors
Inventor: TRIGGS GEOFFREY WILLIAM
IPC: G21C5/08
Filed: 1965-07-28
Abstract: 1,146,152. Moderator structures. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 21 July, 1966 [28 July, 1965; 21 March, 1966], Nos. 32380/65 and 12419/66. Heading G6C. A nuclear reactor core structure comprises an assembly of prismatic blocks of neutron moderating material, e.g. graphite, arranged end to end in columns, having fuel element channels passing through the structure and keying members fitted in keyways orientated so as to be radial relative to the axes of the blocks to key the blocks together, the outer blocks being secured to a rigid restraint structure surrounding the core structure by pivoted links permitting, on the one hand, movement of the links and outer blocks in a direction parallel to the longitudinal axes of the columns and causing, on the other hand, the outer blocks to follow the expansion and contraction of the restraint structure by tensile and compressive stresses respectively in the links. In one embodiment, each of the pivoted links 31 is in two parts 32, 33 coupled by a shackle 34. Coupling bars 35 are fitted in longitudinal holes 36 in the outer reflector blocks 2 which have cut-away portions 37 to allow for connection of the links 31 with the bars 35. The ends of the parts 32 are pivotally connected with the bars 35 by horizontal pivot pins 38. The ends of the parts 33 are pivoted on brackets 39 welded to the surrounding restraint cylinder 30. Blocks 40 are pivoted on vertical pivot pins 41 mounted in the brackets 39 and the ends of the parts 33 are pivoted on the blocks 40 by horizontal pivot pins 43. The links 31 are adjustable in length by means of the shackles 34 and this, together with the fact that the links 31 are pivoted about the vertical pins 41, allows some latitude in placing of the reflector blocks 2 during the building up of the core structure. In another form, suitable for use in earthquake zones, the pivoted links are made in flat plate form and are secured against movement in the planes of the plates. A circumferential channel 24 is formed around the lower end of each of the core blocks 4 in the bottom layer and these channels 24 are connected with the bores 5 of the blocks by radial ports 25. The channels 24, in combination, form a common gas voidage space 26 extending across the lower end of the inner core region 3 of the structure. Tubes 27 forming part of a structure for support of fuel elements in each channel 8 extend downwards from the apertures in the bottom support plate 6 and have coolant gas inlet ports 29. The gaseous coolant is passed through the core structure in two fractions, the first being passed directly into the bottom end of the fuel element channels 8 through the ports 29 and the second being passed down moderator coolant channels 9 defined between the columns of core blocks 4. The second fraction enters the common gas voidage space and then passes through the radial ports 25 to join the first fraction.

Title: Improvements in or relating to television or the like systems
IPC: H04N5/04
Filed: 1929-10-26
Abstract: 338,330. Gramophone Co., Ltd., and Manifold, M. Bowman-. Oct. 26, 1929. Synchronous movements. - In a television system employing the same, channel or carrier wave for the picture and synchronizing signals, the control of the motor at the receiving station. is automatically effected by a train of oscillations of the synchronizing frequency transmitted between successive groups of the picture oscillations. At the transmitting station a scanning disc 1 provided with apertures or lenses is mounted on the shaft of a phonic wheel motor 3, 4 supplied with current .from a valve generator 5 controlled by a tuning fork 6c. The synchromizing oscillations are applied through a transformer 14 to output terminals 12, 13 by a disc 7 and a conducting sector 8<1> on a disc 8 during the period when the picture oscillations are disconnected by an insulating sector 9' of a disc 9. The picture oscillations are transmitted from a photo-electric cell 10 through an amplifier 11. At the receiving station the picture and synchronizing signals entering at the terminals 15, 16 are applied respectively to a neon tube 20 by discs 17, 19 and through discs 17, 18 to the windings 27a maintaining a fork 26 in vibration. A second, winding 27b is connected through the primary coil of a transformer 29 to the plate of a valve 28 whose grid circuits is completed through a third winding 27c. The field magnets 24 are connected to the plate of a valve 25 whilst the grid circuit includes the secondary coil of the transformer 29 shunted by a. condenser 30 to tune the circuit to the frequency of the fork 26. If the forks are vibrating in the same phase when the synchronizing oscillations are received, the amplitude only of the fork 26 will be increased. Should the fork 26 be out of phase and behind the fork 6c, the electromagnet of the fork 26 will be energized earlier and the impulses transmitted to the transformer 29 will be. accelerated. The accelerated impulses in the circuit of the valve 25 will be effective on the field magnets 24 to accelerate the phonic wheel 23.

Title: Improvements in or relating to the process for the production of a high quality lubricating oil
IPC: C10G21/08
Filed: 1952-12-30
Abstract: Acid mineral lubricating oil fractions having a neutralization number above 0.5 are refined by solvent extraction, with a solvent selective towards aromatics, in the presence of an amount of ammonia less than 1 per cent. by volume based on the lubricating oil.  The solvent-free raffinate may have a neutralization number below 0.1.  Selective solvents mentioned are phenols, furfural, liquid sulphur dioxide, nitrobenzene, aniline, cresols, chlorex, dimethylformamide, dipropionitrile and amines, with or without modifying agents such as water, alcohols and esters.  The ammonia may be added in the form of ammonium hydroxide.  In examples, acid mineral lubricating oil fractions are subjected to countercurrent solvent extraction with phenol in the presence of ammonia, the ammonia being either introduced at a separate point into the extraction zone or introduced in admixture with the phenol.  The extract phase contains naphthenic acids and their salts.  The raffinate phase may be subjected to a further solvent extraction with phenol in the absence of ammonia or may be subjected to clay treatment.

Title: Circuit arrangement in a pabx (private automatic branch exchange)
IPC: H04Q3/00
Filed: 1960-09-26
Abstract: 945,035. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Sept. 26, 1960 [Sept. 24, 1959], No. 33074/60. Heading H4K. In a PABX system in which, on a call to the main exchange, the current over the exchange line is reversed when the called party replies, the connections to the exchange line at the PABX are reversed if necessary when it is first taken into use by a relay which operates or not according to the direction of current flow. Call to main exchange.-The exchange line HC is marked idle by the unoperated condition of relay R108. The calling loop is extended over switch V to line relay R104. Relay R106 operates after a delay and closes a highresistance loop across the line HC including rectifiers L1, L2. If the direction of current supplied from the main exchange is such that the rectifiers are conductive, A.C. from a source Su is effective through transformer Tr2 and transistor T1 to operate relay R114 which connects up R117 to reverse the connections to line HC. Relay R110 pulls up followed by R107, R111 and completes a low-resistance loop, and dialling impulses are repeated by R104, R106. The reversal of line current when the called party replies causes operation of R114 which connects up R108. Upon release by the calling party, relays R104, R106 and R110 relapse in twin, opening the main exchange loop, and R107 follows after a delay imposed by condenser C1 When release occurs at the main exchange, the line current is again reversed, and R114 falls back followed by R111, R108 and R117 if operated. Release under fault conditions.-It may happen that relays R108, R111 and R114 remain operated after the line is released at the main exchange, and a circuit (which may be common to a number of lines) comprising relays R102, R103, R109 and a transistor T2 is provided for dealing with this situation. On the release of R107, relays R103, R102 pull up and then fall back slowly in turn under the control of condensers C2, C3, so that R101 energizes momentarily and closes a low-resistance loop over the exchange line. If dial tone is received it is effective through transistor T2 to operate R109 which releases R108, opening the loop. The action is repeated if necessary until either dial tone is received or B114 is released by a reversal of line current. Incoming call.-Relay R116 responds to ringing current followed by R 115, R111 Upon reply at the PABX the switchboard R104 energizes, and as in the case of an outgoing call, the line HC is looped. Ringing is cut off at the main exchange, and if R114 is not operated a circuit is made for reversing relay R117 so that the line current is such as to operate R114.

Abstract: 466,571. Television transmitters. RADIOAKT.-GES. D. S. LOEWE. Nov. 29, 1935, No. 33144. Convention date, Dec. 1, 1934. Addition to 441,761. [Class 40 (iii)] The parent Specification discloses a system of inserting synchronizing signals in the image signal train by rendering a valve 10, Fig. 1, conducting and so reducing the potential of the line 5 connecting the image signal amplifier 2 to the transmitter 4. According to the present invention, the condensers 6, 7, are avoided and the line 5 is connected to a source of negative potential during the synchronizing signal periods. Control signals are applied from 12, Fig. 2, to render valve 10 conducting and connect the line 5 to a source 9<1> of negative potential. The amplitude of the synchronizing signals may be varied by varying the voltage of 91, but the grid bias 11<1> must also be varied and this is preferably done by varying an earthed tapping on a single source comprising 91 and 11<1>. The control signals are preferably produced by light 13, Fig. 3, falling on a cell 17 through the scanning aperture at the end of each line. Specification 464,049 is referred to.
