Title: Method of copying magnetic recordings
IPC: G11B5/86
Filed: 1972-10-18
Abstract: 1355895 Copying magnetic records PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Oct 1972 [21 Oct 1971] 47924/72 Heading G5R A method of contact copying a magnetic recording from a master 5 on to a slave 8 of coercive force H c2  uses a magnetic transfer field H, where H > aH c2  (1 < a < 2), in the contact region 13, and involves increasing the coercive force of the master 5 prior to copying, relative to the coercive force it had when it was itself recorded, to a value H c1 , where H c1  > aH. The choice of a is determined by the gradient of the respective remanence curves. Where the coercive force of the magnetic material of the master is markedly temperature-dependent, the master may be cooled (or heated, as appropriate), e.g. by a cooled metal shoe 16, to increase its coercive force. Such materials are cobalt-doped iron oxides of the formula (Co x Fe 1-x ) 2 O 3 , where 0.01 < x < 0À1. If the coercive force of the slave is not also markedly temperature-dependent, the master and slave may be cooled together, wound on a common reel, and exposed then to the transfer field, Fig. 7 (not shown). Alternatively, where the magnetic material of the master is of the general formula M 5 R, where M is Fe, Co or Ni and R is a rare earth metal (e.g. Co 5 Sm), the master may be subjected, prior to recording thereon, to hydrogen gas under pressure, which is known to reduce the coercive force. The gas pressure is removed prior to copying to allow the coercive force to increase again. A method of manufacturing cobalt-doped iron oxide tapes is described which includes mixing a cobalt compound such as CoCl 2 .6H 2 O with γ-Fe 2 O 3  in water, adjusting the pH thereof and stirring for 30 minutes. The mixture is filtered and the filtrate heated to 425‹ C. in a reducing atmosphere to produce cobalt oxide, and then in an oxidizing atmosphere. The resulting powder is mixed with a binder and applied as a thin layer to a carrier.

Abstract: 1536974 Welding by pressure SOC NATIONALE INDUSTRIELLE AEROSPATIALE 18 Nov 1976 [25 Nov 1975] 48139/76 Heading B3R In a method of welding a corrugated element to a non-corrugated element, the corrugated element is spot-welded along its corrugations to the non-corrugated element and so placing the structure formed under stress, the structure is then heated in a controlled atmosphere furnace (e.g. a vacuum for 2 hours at between 800‹ to 950‹ C.) to increase the area of each weld by diffusion welding and stress relieve the structure. A number of the structures may be similarly welded together to produce a sandwich-type structure. Both elements may be of Ti or Ti alloy.

Abstract: 1,024,603. Photographic colour printing. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Dec. 11, 1963, No. 48915/63. Headings G2A and G2J. In apparatus for colour printing, the surface to be illuminated receives light through an arrangement of light-conducting fibres, which originate in a number of separate bundles according to the number of colour components to be mixed. Fig. 1 shows the construction of the bundle of fibres, which are grouped at one end into three separate branches 6, 7, 8, for use in three-colour synthesis. At the light outlet end 12 the fibres are arranged in sets of three, one from each branch, as at 13 (Fig. 2). Each branch has a separate light source 1, 2, 3, and colour filters 9, 10, 11 to produce the three different colours which are synthesized to produce a uniformly coloured illumination of the original 4 which is to be copied. The amount of the individual colour components can be varied by altering the intensity of the light source, the degree of transparency of the filters, or by additional grey filters. In Fig. 3 the branches 6, 7, 8 are shaped so as to receive the incident light from a single source 14. Instead of using colour filters, the fibres themselves may be coloured.

Abstract: 493,413. Calculating - apparatus. KOOPERATIVA FORBUNDET, FORENING U.P.A. Dec. 23, 1937, No. 35646. Convention date, Dec. 28, 1936. [Class 106 (i)] Transfer mechanism for calculating machines having independently actuated denominational totalizer wheels comprises transfer members 20 rockably mounted concentric with the axis of the totalizer wheels or with actuating gears therefor, each member 20 carrying a feed pawl 21 co-operating with the next higher denomination totalizer wheel or with its actuating gear, and detaining members 24 which are rocked by the tens tooth 19 of a totalizer wheel to release a transfer member and are provided with cam surfaces cooperating with an abutment to prevent locking of the transfer member until it has completed its to-and-from motion. The totalizer wheels are rotated by setting racks and after this operation levers 15 are moved by cams on the driving shaft of the apparatus and all transfer members are released. If a member 24 has also been moved by a tens tooth the particular member 20 is freed and is rotated clockwise by a spring. Levers 15 then restore the members 20 to their original positions and in the process pawls 21 move the higher denomination wheel one step. In the construction shown in Fig. 5 the member 20 is then locked by an abutment 29 thereon engaging in a pawl 24 on a fixed axis. In the construction shown in Fig. 2 the member 24 is mounted on the member 20 and engages with a fixed abutment 35 to produce the same effect. In the latter construction the transfer arrangements are connected with a gear 34 which can drive either totalizer wheels 1a or 1b through a movable gear 32. The tens teeth 19a and 19b in this case act through the intermediary of levers 39 on detaining members 24. In order to prevent overthrow the levers 15 may press on a tail piece of pawls 21 and hold the latter in positive engagment with the ratchet teeth 22 on the higher denomination wheel. Arrangements must then be made to move the levers 15 to free the totalizer wheels when it is desired to zeroize the apparatus.

Abstract: 1,138,270. Luminescent display with a memory. NATIONAL CASH REGISTER CO. 1 Nov., 1967 [30 Nov., 1966], No. 49635/67. Heading G5C. A display device comprises a display surface 18, Fig. 2, which fluoresces in U.V. light and whose local light emitting properties vary according to the heat applied thereto; a plurality of heat applying magnetic elements 10 formed from a material having a closed hysteresis loop; a bias element 16 associated with each heating element 10 and settable by means of an information-bearing signal to one of two states to bias the elements 10 accordingly; and means for applying a switching signal to the elements 10 to cause those of them which are biased into the correct state to cycle around their hysteresis loop and thereby generate heat. Applications are described to both monogrammic and entire alphanumeric outputs. Display surface.-As described, the surface 18 is coated with a phosphor (e.g. Ag/Ni treated ZnCd sulphide) and bathed in U.V. light; such an arrangement fluoresces but is heat-quenched, as described in U.S. Specification 2,642,538, to display the required pattern. Heating application.-The heat pattern may be applied through a conducting plate shaped as an entire alphanumeric character, Fig. 7 (not shown), or directly by elements forming a monogrammic sign, Fig. 4. By applying the biasing signal to selected ones of the lines A . . . I selected fluorescent areas 41 are extinguished. Biasing.-The biasing elements 16 are each magnetically coupled to their associated heatgenerating element 10. Both exhibit uniaxial magnetic anisotropy; the coercivity of element 16 is greater than that of element 10; thus an applied field may switch the state of element 10 but not of element 16. A current passed through X-conductor 12 causes the magnetization of element 16 to rotate into the hard direction, and termination of the current results in its breakup into a multidomain state. No bias is therefore applied to element 10 and the latter is allowed to undergo heat-producing hysteresis cycles when an A.C. switching voltage is subsequently applied to Y-conductor 14. But if a current pulse along conductor 14 first causes element 16 to rotate into the easy direction, this prevents element 10 from cycling in response to the switching voltage. In the embodiment of Fig. 4, elements 39 act to bias elements 41, 38 is a common X-line, and A ... I are the Y-lines. The matrix 43 may be computer-controlled, Fig. 5 (not shown); or the bias element may be switched by means of a magnetic " writing pen ", Fig. 6 (not shown).
