Title: Improvements in or relating to the automatic frequency control of electric oscillation generators
Inventor: BRYDEN JOSEPH EASTO
IPC: H03C3/09
Filed: 1954-04-09
Abstract: 775,572. Automatic frequency control systems. GENERAL ELECTRIC CO., Ltd. April 6, 1955 [April 9, I954], No. 10551/54. Class 38 (4). The mean frequency of a frequency or phase modulated oscillator 3 is retroactively stabilized by mixing its oscillations with those of a constant frequency U.H.F. oscillator 1 to derive a transposed U.H.F. output also frequency or phase modulated which is applied to a cavity resonator 12 whose resonant frequency is cyclically varied, e.g. at 50 c/s. mains supply frequency, by a disc inside the cavity rotated, e.g. at 25 c/s., by a motor 14. Detected amplitude variations of an output of the resonator (at 50 c/s.) are then, after amplifying, applied to a sense discriminator 20 to which a reference frequency 50 c/s. driving the motor is also applied so that the detected output is of polarity and magnitude dependent of any variations of the mean frequency of the oscillator 3 and is applied to stabilize it. Alternatively the resonator may be an enclosed coaxial line section. Specifications 738,159 and 765,453, [Group XXXVI], are referred to.
Patent GB-105853-A (GB)
IPC: C22B34/12
Abstract: 105,853. Wade, H., (Titanium Alloy Manufacturing Co.). Aug. 14, 1916. Titanium basic sulphate containing a preponderating quantity of titanic oxide, and less sulphuric anhydride than combined water, say 70-80 per cent. titanic oxide, 15-20 per cent. combined water, and 5-10 per cent. sulphuric anhydride, which yields on calcination a pure titanic oxide, is obtained by boiling a solution of titanic sulphate which may be neutral or contain some free sulphuric acid. The titanic sulphate solution may be prepared from any titaniferous material, preferably from a product obtained by fusing titaniferous material with alkali sulphide and boiling the product (with or without a preliminary water lixiviation) with sulphuric acid of such dilution as to dissolve only the iron; the residue is heated with strong sulphuric acid to obtain the titanic sulphate solution. If iron is present, it is preferably reduced to the ferrous state for instance by sulphurous acid or preferably by electrolysis in the cathode compartment, the anode compartment being filled with very dilute sulphuric acid. The reduction should not be carried beyond the stage at which a slight violet colouration is produced owing to the formation of a little titanous sulphate. During boiling to precipitate the basic sulphate, some oxidation of the titanous sulphate occurs, but if the reduction has proceeded too far, a limited quantity of an oxidizing agent, preferably nitric acid, should be added to oxidize most but not all of the titanous sulphate, leaving all the iron in the ferrous condition.

Title: Improvements in or relating to roll film cameras
IPC: G03B19/04
Filed: 1940-06-20
Abstract: 536,555. Roll-film cameras. KODAK, Ltd. June 20, 1940, No. 10616. Convention date, Oct. 21, 1939. [Class 98 (i)] The film re-winding knob of a camera is normally latched in an inoperative position, and after unlatching is slidable on a tubular cassetteengaging member to a position away from the camera body in which it can be operatively engaged with the tubular member to re-wind the film. As shown, the film re-winding knob 6 is held in inoperative position in a recess in the camera body by a latch on a semicircular locking bar 17 pivoted on a screw 18 and having a lug (not shown) which engages a groove 15 in the knob member. In this position a pointer 9, which engages the knurled edge of the knob to prevent it rotating, indicates which of the types of film shown on an exchangable dial plate 7 on the knob is in use. When the film is to be re-wound, the locking-bar 17 is operated by a handle 19 to release the knob, which is then pressed upwardly by a helical strip spring 22 until a cross-bar 26 extending from a pin 38 depending from the knob may be engaged in a slot 27 in the closed upper end 36 of a tubular member 28, thus allowing the member 28 to be rotated by the knob. The lower end of the member 28 is formed with slots 29 to engage the winding pin R<SP>1</SP> of the film spool. To remove the cassette or film spool, the knob 7 is pulled out beyond the re-winding position, so that a head 39 on the pin 38 engages the underside of the end 36 of the tubular member 28 and draws the latter up to disengage its lower end from the spool. A spring 32 snapping into a groove in the side of the tubular member holds the latter in its normal position.

Patent GB-1435074-A (GB)
Title: Domain wall information storage
IPC: G11C11/14
Filed: 1974-03-12
Abstract: 1435074 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 12 March 1974 [26 March 1973] 10864/74 Heading H3B Information which may be binary, ternary, or use a higher radix such as decimal, is stored along and within a domain wall in an anisotropic magnetic layer, the information being represented by the rotational direction of magnetization imparted to discrete zones extending along the wall. The layer anisotropy may be uniaxial or biaxial, and extends either coincidently with or orthogonal to the layer plane. As shown in Fig. 1(a) a reversal of magnetization rotational direction (or chirality) along the length of a domain wall forms a dividing wall line which itself has a chirality in one direction or the other. The discrete information storage zones may be constituted either by the regions between the wall lines or by the wall lines themselves. Figs. 2(b) or 2(e) show storage arrangements in which the two directions of chirality between wall lines are represented by diagonal hatching, while the two directions of chirality within a wall line are represented by polarity signs. In Fig. 2(b) the presence of a wall line denotes a binary "L" and its absence a binary "O", while in Fig. 2(c) the + and - chirality of the wall line presents "L" and "O" respectively. A combination of all possibilities provides a ternary system, Fig. 2(d). In a modification, Fig. 2(e), the domain wall is cylindrical and the number and chirality of pairs of wall lines denotes the digit stored. The general arrangement uses stripe domains which are parallel and uniform for an easy magnetization axis in the layer plane and non- uniform for an orthogonal easy axis, Figs. 3(a) and 3(b) (not shown). A wall propagation system for the stripe domains is shown in Fig. 6, in which alternating current in a right hand edge conductor (shown diagonally hatched) causes the injection of a new domain, while synchronized current in a left-hand edge conductor causes a displaced domain to be ejected. The combination of chiral wall line storage and wall propagation is used to form a co-ordinate storage system comprising a storage layer 70, Fig. 9, and a drive layer 71. The domain walls in the two layers are mutually orthogonal, and are respectively propagated to displace stored information by alternating current in edge conductors 75, 74. In the storage layer 70 each wall line is defined by the intersections of the orthogonal domain walls, Figs. 8(a) and 8(b), the wall lines of the storage layer storing binary information. These two figures show the magnetic effects in a storage layer with in plane and orthogonal easy axes, respectively. Writing to determine the chiral state of an addressed zone can be effected by a magnetic bias, while reading may be effected inductively or magneto-optically.
