Patent GB-1330941-A (GB)
Title: Data processing system
IPC: G06F9/308
Filed: 1971-05-27
Abstract: 1330941 Digital computers INTERNATIONAL STANDARD ELECTRIC CORP 27 May 1971 [18 June 1970] 17515/71 Heading G4A A digital electric data processing system comprises a memory MEM holding first data words and at least one instruction word holding first information and an address which are used to find, in combination with information in a second word, a slice in a first word. The system includes a plurality of tables of first data words, each table being formed by a plurality of adjacent non-overlapping slices of equal length. The first information comprises a P bit binary number with decimal value M determining a slice length L = 2<SP>m</SP> and the address gives access only to the table containing slices of this length. The second word indicates the position of the slice in the accessed table. To define N different slice lengths in a 2<SP>n</SP> bit word where L = 2<SP>m</SP>, P bits are required where 2<SP>p-1</SP> < N # 2P. Using this formula the number of bits in the instruction word required to define a slice can be reduced. The Apparatus.-This comprises the memory MEM and an arithmetic and control unit ACU, the former holding 16 bit instruction words and 16 bit first data words. The data words are formed of equal slices SL0-SL3, and the data words are formed by slices of equal length being in a same table of the memory. Operation.-Before a load slice instruction is received, index register X is loaded from memory MEM with a second data word which comprises the address of the first word in a table followed by a position address of a slice in the first word. Then a 16 bit load slice instruction, comprising 67 function code bits, 2 bits indicating the slice length (i.e. 1, 2, 4 or 8), and 7 bits which, in combination with the second word, locate the desired slice, is read from memory MEM. The apparatus operates in up to four cycles, F, 1, A, and B, in each of which four timing pulses are generated in succession. The two slice length bits are transferred to a slice decoder SDEC at the same time as bits X12-X15 from the X register. The SDEC contains a first gate to determine the length of the slice from the two bits. The first and last positions of a slice in a word are obtained by completing N-M slice position indicating bits at the right hand with O<SP>1</SP>S and 1<SP>1</SP>S respectively until an N bit number is obtained. When the first and last bit positions of a slice have been determined, mask signals are generated in circuit MGC.

Patent GB-358427-A (GB)
Title: Improvements in or relating to stop-motion or delivery-stopping mechanism for twisting machines
IPC: D01H13/18
Filed: 1930-06-06
Abstract: 358,427. Delivery stopping apparatus for twisting-machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Whitin Machine Works; Whitinsville, Massachusetts, U.S.A.) June 6, 1930, No. 17557. [Class 120 (ii).] A stop-motion for twisting-machines comprises a support having a fixed clamping bar thereon, and a movable clamping bar pivoted thereon and movable by its own weight to clamp the yarn, the movable bar being held inoperative by a latch which is released on yarn or thread breakage. The yarn Y, Figs. 1 and 4, passes from the bobbins S through the guides 62, between the two clamping bars 26, 28, over a porcelain rod 30, under detectors 42, one for each strand, round the feed rolls 19, 21, under the hook 56 of the detector 53, and is finally wound on the bobbin B by the ring and traveller 14. The detectors 42, 53 are attached to members 40, 50 which are pivoted freely on the bar 35 and which have downward extensions 44. When a yarn breaks and allows one of the detectors 42 to fall, or when the thread breaks and allows the detector 53 to fall, an extension 44 engages a pin 45 on the latch 46, releases the hook 65 and so allows the weighted clamping bar 34, 36 to swing round and clamp all the yarns Y against the bar 28. In order to facilitate re-threading after yarn breakage, a crank 70 is provided and holds the members 42, 56 in normal running position. The arm 53 has attached a counterweight 58, which is so adjusted that the stop motion is not operated when the arm 53 swings down slowly e.g. when the yarn slackens due to the whole machine being stopped. The pin 45 is thus only engaged when the arm 53 swings down suddenly and is carried by inertia past its position of rest as determined by gravity. In a simplified construction the detectors 42 are dispensed with, the stop-motion being operated only upon breakage of the thread below the feed rolls.

Abstract: 1447051 Tubular heat exchangers; boilers UNITED KINGDOM ATOMIC ENERGY AUTHORITY 28 March 1974 [16 April 1973] 18312/73 Heading F4S and F4A A shell and tube heat exchanger, for use in a nuclear reactor for heat exchange between primary and secondary sodium, comprises a plurality of tubes 1 the ends la of which extend between cylindrical tube sheets 4 incorporated in a central tube member 3. Within the tube member 3 is disposed a removable tubular baffle 5 which seals against the wall of the tube 3 between the tube sheets 4 to define two coaxial flow ducts 6 and 7. The baffle 5 is double walled to define an argon filled interspace, the inner wall being formed with an expansible region 5a to accommodate differential expansion of the walls. In an alternative construction (not shown) the tubes 1 are of helical form. The heat exchanger, which is enclosed within a housing 10, is arranged to depend from the roof (9, Fig. 1) of a nuclear reactor. Primary sodium enters a distribution plenum 14 via an inlet port 11 in the housing and after passing downwardly over the tubes 1 leaves via an outlet 13. The flow of primary sodium into the plenum 14 can be controlled by movement of a vertically slidable sleeve 19. The plenum 14 is bounded by perforate baffles 15, 16 and 18. A cylindrical baffle 8 prevents direct impingement of the primary sodium on to the tube 3 and tube sheets 4. Secondary sodium entering through an inlet port (21, Fig. 1, not shown) flows downwardly through duct 6 and then upwardly through the tubes 1 and outer duct 7 to finally leave through an outlet port (22). Removal of baffle 5 permits inspection and, if necessary, plugging of defective tubes. Heat exchange coils 20 are provided to remove residual heat from the shell when the reactor has become inoperative. A drain tube 23 extends from the bottom end of tube 3 to a drain facility situated between two spaced annular seals (24, 25) which close the upper end of duct 7.
