Title: Improvements in and relating to Machines for Forming Wound Rolls of Sheet Material
Inventor: PREEN ROBERT
IPC: B65H19/29
Filed: 1967-08-29
Abstract: 1,174,634. Coating apparatus. T. H. DIXON & CO. Ltd. 27 Aug., 1968 [29 Aug., 1967], No. 39467/67. Heading B2L. [Also in Division B8] The tail or free end of a wound roll of sheet material, such as toilet tissue, is secured to the next layer by applying to the outside of the roll at least one circumferential band of adhesive which is liquid at the time of application and is capably of effecting at least temporary adhesion of the tail without impregnating underlying layers thereof. Apparatus for applying said band comprises an applicator roller, a second roller parallel to and spaced from the applicator roller by a distance less than the diameter of said roll, means for driving the rollers at constant speed in the same direction, means for receiving said roll and delivering it in the nip between said rollers, and ejector means operating in unison with said delivery means for ejecting the roll after the application of a circumferential band thereto. A hollow shaft 12, mounted above a tray 10 containing wax-like adhesive maintained in liquid form by a heating element 11, is formed with a plurality of spaced-apart roller portions 23 which dip into the adhesive and co-operate with doctor blades 41. A hollow shaft 13 parallel to shaft 12, is formed with roller portions 25 aligned with the portions 23. Shafts 12, 13 are rotated in the same direction by a chain 16 from a motor-driven shaft 19. The piston rod of a pivoted pneumatic cylinder 30 is connected to an arm 29 rigid with a journalled shaft 28. Arms 31, rigid with the respective ends of shaft 28, carry respective pins 33 on which is pivoted a trough 32 rigid with a 'bar 36 formed with a slot 37 slidably engaging a fixed pin 38. The piston rod of cylinder 30 is initially rotated to position trough 32 in the raised, dotted-line position for receiving a newly-wound long roll or log of toilet tissue. The piston rod is then extended to lower trough 32, which thus pivots through 90 degrees to deposit said roll between the rollers 23, 25. Adhesive from the rollers 23 is thereby applied in circumferential bands to the roll. Shaft 12 is heated internally to maintain the adhesive or rollers 23 in liquid form, and shaft 13 is cooled internally to solidify the liquid applied to the roll. After the latter has made more than one bit less than two complete revolutions, the piston rod is retracted, whereby bars 40, carried at the ends of arms 39 rigid with shaft 28, engage the roll and eject it through the gap between rollers 25 and the ascending trough 32.

Title: Asynchronous digital computer
IPC: G06F9/38
Filed: 1961-11-13
Abstract: 1,008,775. Digital electronic computers. GENERAL ELECTRIC CO. Ltd. Nov. 13, 1961 [Nov. 21, 1960], No.40597/61. Heading G4A. A binary serial-mode computer in which instructions and data are stored on a magnetic drum 10 is arranged to operate partly with single address and partly with two-address instructions, each word read from the drum being passed to a register such as 32 or 33 via an arithmetic unit 25 so that the simpler instructions may be carried out in one word-time. Where possible instructions (single address) are placed in alternate locations on the drum, and the operand required by a given instruction is placed in the next location. When an operation is to occupy more than one word-time, or the alternate arrangement of instructions and operands is not possible, a two-address instruction (double length) is used, one bit of the first word being reserved for indicating this; the second address then being that of the next instruction. An address consists of seven bits specifying a track on the drum, and seven specifying a sector, and a comparator 27 locates the desired sector by comparison with the contents of a counter 26 receiving sector pulses. Single-length instructions are read through 25 into the α-register 32 where they control the reading of an operand or the storing of a calculation result on the drum, the address being selected by units 26-28 and 16, and the data being passed (usually to or from A-register 54, an accumulator) via 25 and parity bit circuits 17 or 29 for checking or inserting check bits. For example, a single-address instruction to add to the contents of the A-register the contents of the next sector of the drum causes the former to be read to 25 via line 59 simultaneously with the arrival of the latter on line 18, an instruction decoder 22 commands addition and the result is returned to the A-register. The X-register 48 is used for modification of instructions and branch instructions-always double length in the latter case-and the Q-register is used for multiplication and division when it holds the least significant part of the product and quotient respectively. An N-register forms an input-output buffer between tape-reader 225 or typewriter 221 and the A-register, and I-register 90 is adapted to receive data for real-time operation with an external data-source. Some logical circuitry of the arithmetic unit and of instruction sequence unit 34 is described (Figs. 2 and 3, not shown).

The source 11, e.g. of X-rays, is secured to a toothed belt 14 and coupled 19 to the detectors 12 so that they move with the source along fixed guides 18, the belt 14 being reciprocately moved by a driven shaft 15. The source and detectors are mounted on rotatable member 1 which is indexed 10 degrees after each transverse scan by motor 9. Each detector comprises a scintillator and a photomultiplior with its own collimator 13 1 -13 n . The body 5 is located on a support 4 within a water bag 7 in a two-piece collar 6a, 6b. During each lateral scan output signals are derived representing the transmission or absorption along 30 parallel sets of beam paths in the planar section (slice) under examination. A photo-cell 20 monitors the lateral scanning displacement. The number of detectors may be halved by displacing the detectors sideways after each 180 degrees of orbital movement or between each lateral scan, an orbital step being only effected after two such scans. Two attenuating blocks 21 and 22, e.g. of " Perspex " (Registered Trade Mark), are fitted round the patient's collar 6a, 6b and secured to the rotating member, these blocks being free to turn round the collar. A lead block 23 is positioned above block 21 at one side and a reference detector 27 is mounted close to the X-ray source. A processing circuit for each detector is described with reference to Fig. 2 (not shown), each of these circuits being the same as that described in Specification 1,471,531. The two attenuating blocks may be replaced by four shaped attenuating (aluminium or carbon) blocks, Figs. 3 and 4 (not shown), to provide the required correction to the beam paths for all beam positions so that if the body 5 is replaced by a constant reference absorber the absorption is constant across each lateral scan. The water bag may be replaced by a polystyrene or rubber foam impregnated with an absorbing material such as lead or molybdenum.
