Title: Improvements in or relating to information storage apparatus
Inventor: KILBURN TOM
IPC: G11C17/02
Filed: 1957-10-30
Abstract: 897,957. Digital data-storage apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 29, 1958 [Oct. 30, 1957; Dec. 13, 1957; Aug. 7, 1958], Nos. 33942/57, 38825/57 and 25354/58. Class 106 (1). Information is stored by positioning an induction-affecting member close to or distant from a pair of inductively coupled conductors. The invention is applicable to instruction and access devices in computers in which the information is of a semipermanent nature. In a matrix the coils 1b, 2b are oppositely wound. When therefore the coils 1a, 2a are energized by current through a horizontal conductor 3 one or other coil 1b, 2b is energized according to the position of a slug 6 to read out binary digit 1 or 0 in the associated column. The coils may be printed on opposite sides of a card and the slugs 6 may be moved by air pressure under the control of electromagnetically controlled reversing valves 22a-22c, Fig. 4. A long card of any suitable form may be used with a carriage 145 traversing the card, Fig. 14. Photo-electric equipment 149 ensures alignment of the pneumatic apparatus with the holes bearing the slugs. The reversing valves 1402 are controlled via electromagnetic relays 1403 by data from a tape reader or electronic store 1408. The slugs are thus set column by column as the carriage traverses the length of the card. The slugs are limited in movement (Figs. 5, 6, not shown) or are mounted on rods, Fig. 7, for movement by mechanical means. Such movement may be preceded by resetting by a roller. Fig. 8 shows an arrangement for preventing accidental movement, fabric layers 34, 35 retaining the slugs but yet permitting the passage of an air jet. The structure may be built up from rods 40 with the slugs carried by cross-bars 43a, Fig. 9. For permanent information the slugs may be replaced by paper printed with magnetic ink, two sheets with complementary information being used on opposite sides of the matrix. By duplicating read-out windings wound in opposite directions and connected in parallel, spurious effects due to capacitative coupling are cancelled out (Figs. 10, 11, not shown). Such a structure may be made up of an array of printed circuits (Fig. 12, not shown). Fig. 15 shows a wire mesh with slugs 154 held in place by modelling clay to form an access store.

Title: Improvements in hammers and stamps
IPC: B21J7/24
Filed: 1935-12-12
Abstract: 467,193. Fluid - pressure hammers. MASSEY, Ltd., B. & S., and PICKWORTH, P. C. N. Dec. 12, 1935, No. 34444. [Class 83 (iv)] [Also in Group XXVI] Relates to hammers or stamps of the vertically-opposed tup type operated by steam or compressed-air. The tups are borne by, but mechanically free from, plungers dipping into a common vessel or communicating vessels containing pressure medium ; the cross-sectional areas of the plungers are proportional to the tup weights, and means are provided to maintain constant the volume of the pressure fluid between the plungers. The tups 10, 11 slide between guides 26 in the standards 13, 14. The upper tup 10 is connected to a piston in cylinder 16. The lower tup 11 is reciprocated by hydraulic pressure through rams operated by the upper tup. The lower tup may be equal to or greater in weight than the upper tup. The strokes are inversely proportional to the weights. An oil vessel 17 is arranged below the tup 11 and contains a cover 18 in which are mounted three plungers 19, 20, 21. The plunger 19 engages the tup 11 ; the plungers 20, 21 engage the tup 10. The plungers 20, 21 are completely enclosed in cylinders 24, 25 provided with packing 36 and surrounding sleeves 28, and engage push rods which slide in guides 33 and engage the tup 10. Cavities below the glands 23, 28 are connected by pipes 38, 39, 40 to a sump 37. A motor-driven pump, controlled by the level of the oil in the sump, returns the oil to the vessel 17. The movement of the tup 10 down under steam pressure causes the tup 11 to rise through the action of the plungers 20, 21, 19. When the steam pressure is reversed, the weight of the tup 11 helps to raise the tup 10. The plungers may be housed in connected cylinders instead of working in a common vessel. Alternative automatic means for ensuring the correct quantity of oil in the system consists of two spring-pressed curved levers 43, 44 operated by the tups and connected by links to a bar 49 provided with an electric terminal 51 or a mechanical device controlling the motor 42 which is normally inoperative. Should the oil supply fall below normal, the tup 10 does not reach its top position. The rod 49 is moved to the right and starts the pump. Two plungers may be used to raise the tup 11. Weights may be used to adjust the total weight of the tups when using different dies.
