Title: Improvements relating to fluid operated shift registers
IPC: F15C1/12
Filed: 1964-12-04
Abstract: 1,021,288. Fluid shift registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 4, 1964 [Dec. 19, 1963], No. 49362/64. Heading G4B. [Also in Division G3] A fluid-operated shift register is comprised of a series of bi-stable fluid switches, there being one switch for each stage of the register. Three stages 40, 42, 44 are shown. Each stage consists of a bi-stable amplifier 13, Fig. 1, (not shown) in which fluid from an inlet port 14 will flow either into an outlet 17 or an outlet 18. Control pulses form nozzles 19, 20 deflect the flow into outlets 18, 17 respectively if it is not already flowing into the appropriate outlet. These are denoted as " 1," " 0," respectively in the present example. Fig. 2 shows a shift register in which the stages 42 et seq. are provided with AND gates 47, 49, 50 and OR gates 45, 48. In operation a reset pulse is applied along a duct 62 which operates to set each stage to "0" A set pulse is then passed from a pump 67 through a hole 70 in a revolving disc 69 and along a duct 66 to the AND gates 29, 49, 55. If a pulse is applied to any of these gates by the ducts marked BIT A, BIT B or BIT C, the corresponding stage is switched to " 1." Timing pulses are then applied through further holes 76a, 76b, 76c of the disc 69 to a duct 77. The effect of each of these pulses is to move the information one stage to the right. Because of fluid stream inertia in the channels and as the same timing pulse is used by all stages the output from one stage is available to switch the following stage, if necessary, even though the first output disappears when the timing pulse is applied. If desired information bits may be supplied serially to the first stage only instead of in parallel as described above. They are then applied between the timing pulses. In a modification, Fig. 4 (not shown), the register may have further interconnections making it possible to transfer information to the right or to the left at will. The timing pulses must end before the power streams issue from new channels. To make the duration of the timing pulses less critical, the downstream ends of the " 0 " and " 1 " output channels may be formed as enlarged chambers which thus provide a delay until pressure builds up in the duct.

Title: Improvements in and relating to Magnetic Recording
IPC: G11B11/105
Filed: 1966-11-04
Abstract: 1,155,006. Recording and playback. INTERNATIONAL BUSINESS MACHINES CORP. 4 Nov., 1966 [19 Nov., 1965], No. 49544/66. Heading G5R. [Also in Division H3] A film of anisotropic magnetostrictive ferromagnetic material is mechanically stressed so as to rotate its anisotropy at selected data-storage locations. The film is subjected to a magnetic field of an intensity insufficient by itself to rotate the magnetic vector into a remanent direction but sufficient to do so in conjunction with the mechanical stressing, which is applied by the production of a temperature gradient in the film at the selected locations by means of a laser beam or a beam of low-energy electrons. Playback is effected by scanning with a laser beam and using the Kerr effect. The datastorage locations may be formed as discrete elements of film on a common substrate or as regions in a single film, and the film may be provided with a protective coating, e.g. of silicon monoxide.

Filed: 1964-12-07
Abstract: 1,122,385. Circuits employing bi-stable magnetic elements. PLESSEY UK Ltd. 3 Dec., 1965 [7 Dec.. 1964], No. 49628/64. Heading H3B. A magnetic storage element comprises a thin film F of isotropic material having a rectangular hysteresis characteristic, parallel first and second word conductors U, V and an orthogonal digit conductor D being positioned in operative proximity. All three conductors are energized to write a binary " 1." The film may be of nickel-iron alloy which is deposited on to a glass or copper cylindrical former by evaporation, chemical deposition or electroplating, the first and second word conductors being subsequently threaded through the cylindrical former. A matrix store is shown in Fig. 3 in which a binary word may be stored magnetically along any of the cylindrical films F1-F9. To write a word a first and a second word conductor U, V common to a selected cylindrical film are pulsed at the same time as digit conductors D1, D2 are selectively energized. Coincident energization of the word conductors U, V establishes a circumferential flux in the film which is angularly deflected by current in a digit conductor to store a binary " 1 " at that location. The direction of current in a digit conductor is opposite to store a binary " 0 " in which case the circumferential flux is angularly deflected in the opposite direction. Alternatively a binary " 0 "is characterized by circumferential flux, the digit conductor being unenergized. For reading out the first and second word conductors are both energized in the reverse direction, an output of characteristic polarity being induced in the digit conductor if a " 1 " is stored. An output of opposite polarity is obtained if a binary " 0 " was stored by the method involving flux deflection.

Abstract: 1372289 Reducing ores FIERRO ESPONJA SA 9 Nov 1972 [26 Nov 1971] 51824/72 Heading C7D Particulate Fe or other ores are reduced to sponge metal in a vertical shaft reactor 10 having a reducing zone 12 and a cooling zone 14. Hot reducing gases, e.g. CO+H 2  are fed in at 850- 1100C. through heater 36, combustion chamber 38 and annular chamber 20, the gases moving upwardly and downwardly in the reduction zone 12. Cooling gas enters through chamber 26, and exits with the downward reducing gas stream through chamber 22, the upward stream being removed through pipe 44 and cooler 46. The removed gases are combined in pipe 56, and pass through cooler 58, pipes 60, 64, pump 66, pipe 68 and into either of pipes 70 and 32. The pipe 70 feeds gas back into the cooling zone 14, with make-up gas from pipe 28, and pipe 32 feeds the gas into the heater 36, again with make-up gas prior to entering the reduction zone 12. The gases enter at a constant rate set by controllers FRC-1 and FRC-3. Controller FRC-2 limits the amount of reducing gas which moves upwardly in zone 12. Flow-rates are calculated in pipes 60,64 by FR-5 and FR-6 respectively to keep a constant ratio, and surplus gas is vented through pipe 62. The flow-rate in pipe 32 is compared with that in pipe 64 by FR-4 and FR-6 to keep their ratio constant, a computer 98 acting upon valve 100 accordingly. The cooling gas may be cracked in contact with the sponge iron to effect a carbon coating on the Fe particles.
