Patent GB-712057-A (GB)
Title: Improvements in or relating to granular products and method of manufacture thereof
IPC: C22C26/00
Filed: 1951-11-30
Abstract: In a method of making a body such as a grinding tool in which abrasive grains are embedded in a metallic bonding medium, adhesion is facilitated by coating the grains with a base layer of a platinum group metal followed by a coating of iron, nickel or cobalt.  The depth of the final coating is about ten times the diameter of its molecules.  The bonding medium may be iron, nickel, cobalt or copper and may be applied in the molten state to a backing disc and the grains then distributed into it. Alternatively the coated grains are distributed on to the disc and the bonding deposited electrolytically.  In another modification the embedding of the grains in the bonding medium is effected by a sintering process. When the base layer is to be palladium, the grains are given a preliminary treatment with a stannous chloride solution followed by rinsing and treatment with a solution containing the base metal.  The main coating may then be applied by a treatment with a solution containing the coating metal or by means of the carbonyl of the coating metal, for example, by heating the grains to 100 DEG -130 DEG C. and allowing them to fall through a chamber containing gaseous nickel carbonyl.

Patent GB-285457-A (GB)
Abstract: 285,457. Nistri, U. Feb. 17, 1927, [Convention date]. Sights and methods of sighting. - A periscopic sight for use in dropping bombs from aircraft, is provided with means for determining the " firing angle " by observation of the displacement of a point on the earth, a pendulum device for maintaining the vertical plane of the sight line, and a device for damping the oscillations of the pendulum by intermittent braking operations. As shown in Fig. 4, the device for the determination of the " firing angle " comprises two concentric discs 12, 16 adapted to rotate in opposite directions with a speed ratio of 1 : 3 when the gear wheel 17 is clutched in under the control of a plunger 22 on a handle 15. Adjacent to the discs 12, 16 are two other concentric discs a, b, one driven by a clockwork and the other set according to the height of the aircraft. The disc 12 controls a sight, and when the discs are in gear, the observer rotates them to keep the sight on the target during a period of time corresponding to a third of the time of fall of the bomb as determined by means of the discs a, b. At the end of this time the discs 12, 16 are stopped and the angle of rotation of the disc 16 indicates the " firing angle," at which the bomb should be dropped. This device is situated at 10, Fig. 6, on the periscopic sight, which has an eyepiece 2, a prism 1, an objective 4, and another prism 3. The setting of the disc 16 as aforesaid is converted into a setting of the prism 3 through a rack 11 and suitable gearing. A pendulum 36 is connected to the prism 3 by a belt gear B, whereby the plane of the sighting line is maintained vertical. The oscillations of the pendulum are damped by the intermittent application of a brake 47 to a wheel 34 fast with the prism 3. The intermittent operation is derived through a lever 7 from a cam wheel 55 driven through a worm gear 54 by a windmill 43.

Abstract: 1,103,247. Colour printing control apparatus. PENTACON DRESDEN KAMERA UND KINOWERKE VEB. July 8, 1965, No. 28976/65. Heading G1A. In an exposure control device for use in colour printing apparatus, the sensitivity of the photomultiplier located in the path of the light used for printing, is adjusted to take account of the Schwartzschild exponent p of the photo-sensitive printing material which is being exposed, by making a correction to the time of exposure of the material. In three colour printing, a separate photo-multiplier is used to examine each colour, and each photomultiplier has to be corrected according to the density of the film or negative to be printed, the size of the print to be made, the contrast of the film, and also according to the Schwartzschild exponent. The device of the invention uses two control circuits, each independent of the other, controlling the dynodes of the photo-multiplier. The control circuit 2 associated with correction for the film density, print size or contrast, operates on the three dynodes associated with the cathode of the photo-multiplier 1, while the circuit 3 correcting for the Schwartzschild exponent, controls the three central dynodes 8, 9, 10. The control circuit 3 includes a photo-sensitive resistor 5, also in the light path, which is connected together with variable and fixed resistors 4, 6, 7 and controls the voltage of dynode 9 with respect to constant potential dynodes 8, 10. The setting of resistor 6 is adjusted in accordance with the printing material used and that of resistor 4 to fix the operating points of the circuit. Thus, in accordance with the setting of resistor 6, one operating point is used when the Schwartzschild exponent is 1 or more than 1, causing the exposure to be shortened as required, and the other point used for exponents of less than 1, the exposure being lengthened Fig. 2 (not shown).
