Patent GB-1363058-A (GB)
Title: Magnetic bubble memory
IPC: G11C19/08
Filed: 1973-03-28
Abstract: 1363058 Moving domain storage systems HEWLETT-PACKARD CO 28 March 1973 [5 May 1972] 14974/73 Heading H3B To prevent spurious domain movement in a bubble domain memory when the power supply is terminated, a permanent magnet is used to supply both a bias field normal to the memory sheet and a steady in-plane field. Fig. 1 shows the memory device in which domains are propagated by a rotating in-plane field 18. The circuitry producing this field is such that if the power supply is terminated the rotating field is removed when it reaches the direction shown by vector 18; the steady in-plane field produced by the permanent magnet is also in this direction, and hence holds the domains in the positions they had reached when the rotating field was removed. So that the steady in-plane field does not affect propagation under normal conditions it is cancelled out by a D.C. current supplied to the coils producing the rotating field. Fig. 2 shows the permanent magnet 24 and memory 10 which is angled between the magnet poles so that the magnet field has a bias component normal to the memory sheet and also an in-plane component in direction 18 of Fig. 1. The Bucking supply 34 connected to coil 28 normally cancels this in-plane component. The rotating field is produced by sinusoidal generator 30 and phase shifter 32 connected to coils 26, 28. When the power supply is terminated the rotating field is allowed to reach direction 18 and then generator 30 and bucking supply 34 are switched off, allowing the permanent magnet fields to stabilize the domains.

Slots 9, 10 are provided for initiating a tearing operation to open the packet. A cover sheet, folded about the middle to provide two sides 11, 12, is adhered to the packet about the angle 13 and projects beyond the edges of the packet over the areas 14, 15, 16 to afford projection to the edges when the packets are stacked in a box. In a modification, two opposed sheets are adhered over an area adjacent to all the sides, the corners being circular. Two or more packets may be secured within a single cover sheet and arranged so that the corners may be torn off together, for the simultaneous discharge of the contents, which may be dissimilar commodities adapted to be united in use.

Title: Weakly basic macromolecular anion exchange resins
IPC: B01J41/12
Filed: 1953-06-01
Abstract: A weakly basic anion exchange resin is obtained by heating at a temperature between 75 DEG  and 100 DEG  C. in alkaline solution, a strongly basic anion exchange resin carrying a plurality of tertiary sulphonium groups each having at least two alkoxy aryl groups attached to sulphur.  The total capacity of the anion exchange material is unaffected.  The products are particularly useful for purifying sugar juices.  They may be used in non-aqueous liquids, e.g. alcohols, ethers, esters or halogen alkanes.  In examples: (1) a strongly basic material prepared from trianisyl sulphonium chloride paraformaldehyde and sulphuric acid as described in Specification 737,924 was neutralized with soda lye and heated with 4 per cent caustic soda solution at 120 DEG  C. for 10 hours.  The granular structure of the resin is maintained but the grains shrink; (2) is similar, but the starting resin was prepared at higher temperature and already had a higher proportion of weakly basic to strongly basic groups than the starting material of example (1).

Abstract: 1,062,682. Screen-stencilling on curved surfaces. L. G. DUBUIT. April 12, 1965 [April 14, 1964; Oct. 7, 1964; Nov. 10, 1964], No. 15428/65. Heading B6C. A silk-screen apparatus for automatically printing, in succession, the two large lateral faces of a substantially oval cross-sectioned bottle, comprises two silk - screen printing stations 23 and 24 each of which is arranged to print a respective one of the lateral faces. Each station incorporates a.rotating device for bringing one of the faces into contact with the associated silk-screen. Each bottle is moved from the first station to the second, and in the process turned over by a transfer device comprising a lever 65 having a fork-like end 67, 68 for engaging the bottle. The lever 65 is moved from the position shown in full lines in Fig. 1 to the position shown in dash-and-dot lines by a linkage arrangement 60, 62 driven by a cam 22 deriving its rotation from the main drive of the apparatus through a speed reducer 17. Alternatively the transfer device comprises a pneumatically actuated carriage to move alternatingly between the two printing stations. Each station comprises a silk screen and a squeegee 42 or 43 mounted to remain directly above the rotation axis of the rotating device. Both screens are incorporated in a carriage slidably mounted to move the screens horizontally. Each bottle is fed to the first rotating device by an endless conveyer system which incorporates tong-like positioning and clamping devices which, through cam means, are released immediately prior to the first rotating device and are re-engaged as soon as the printed bottle is released by the second rotating device. Each of these devices incorporates a disc 45, 55, Fig. 3 (not shown), on to which the bottle is pushed by an hydraulically actuated tip 51, 71, which engages the bottle neck. A rack 50 depending from the screen-supporting carriage, actuates pinions driving associated discs 45 and 55. The squeegees are moved up and down by lever linkage 33, 32, Fig. 1, which vertically moves bars 2 and 3 upon which the squeegees are mounted. In an alternative construction the squeegees are moved through cam means, a guide bar moving with the screensupporting carriage incorporating a cam surface upon which followers carried by the squeegees engage. The horizontal reciprocation of the screen-supporting carriage is effected by rotating a disc 13, Fig. 1, which carries a roller movable in a vertical slot incorporated in the carriage structure.

[Class 20 (i).] A mechanical shooting-gallery comprises a pistol range enclosed in a cabinet, a pistol at the front of the range and a number of targets pivotably supported on endless carriers. As shown, the apparatus is enclosed in a cabinet 1 divided centrally by a partition 3 to form two shooting- galleries each provided with an automatic pistol 36 adapted to project balls at targets 9<11>, 10<11>. The targets are mounted on endless bands 9<1>, 10<1> in such a manner as to pass across both galleries. The bands pass around pulleys 13, 14, driven by an electric motor 21 and geared together to rotate in opposite directions and at differing speeds. The targets are hinged at their lower ends, Fig. 12, and are pivoted to clamps 12 on the bands in such a manner as to be movable from their normal erect position when struck by a ball. Fallen targets are returned to upright position by guides 42, and all the targets are maintained in upright position during their out-of-view travel by guides 18, 19. In addition to the travelling targets 9<11>, 10<11>, disappearing targets 32, Figs. 4, 6, and 13, are provided. These targets are pivoted to a link 32<11>, oscillated about a central fulcrum by the motor 21, so as to rise and fall through a slot 32<1> in the platform 8. The upper parts of the targets are pivoted and are displaceable when struck, and are returned to upright position during their downward movement through the slots 32<1>. An oil-retaining packing 35<111> serves to lubricate the moving parts. Stationary targets comprising discs 43, Fig. 14, are also provided and are each formed with a, central hole 43<1> through which a ball may pass to strike a bell 44. Projected balls are returned by shoots 7, Figs. 6 and 8, to receptacles 39 communicating with the magazines of the pistols 36. The pistols are mounted for universal movement, and with their receptacles 39 are removable from their operative positions in order to be stored within the cabinet during transit. The machine is freed upon the insertion of a coin and the manual operation of a knob (not shown). The knob is connected by a cam-slotted link 64, Fig. 8, to a totalizer 60 that counts the number of coins inserted.
