IPC: G01C19/38
Filed: 1957-01-15
Abstract: 815,556. Gyroscopic apparatus. KEARFOTT CO. Inc. Jan. 15, 1957, No. 1533/57. Class 97(3) In a gyroscopic device wherein the rotor and driving motor are enclosed in a long hollow shell, the shell is accommodated in a housing with end walls which support the shell for movement about its longitudinal axis, and an electrolyte which fills the housing supports the weight of the shell and its contents, and forms a thin film between the shell and the housing.. As shown in Fig. 1, the gyroscopic 10 consists of two rotor sections 11, 12 mounted on an axle 13 forming the shaft for the rotor 14 of an electric motor 15, which has a stator 16 with energizing windings 17. End-bells 18 of the motor support bearings 19 for the shaft 13. Side-arms 21, 22 of the motor 15 are journalled in end walls 24, 25 of a hollow cylindrical drum 26 enclosing the gyroscope motor and rotor. The drum may be filled with air or helium or hydrogen, by means of a small filling tube 27. Electrical terminal plates 28, 29 are mounted on the end wall 24 of the drum, and are connected to the windings 17 of the motor. Electric current is supplied from plates 38, 39, separated from plates 28, 29, through an electrolyte which fills a housing 43 and .supports the weight of the drum and its contents. A hub 42 on the housing 43 supports a longitudinally adjustable jewelled bearing 45 supporting one end of the drum 26. The other end of the housing 43 is closed by a cup 46 fitting inside the housing and bolted thereto by bolts 75. Cup 46 is formed with a hub 47 carrying a jewelled bearing 48, also longitudinally adjustable, supporting the other end of the drum 26. Hub 47 also co-operates with a braking cylinder 52 on the drum 26 to provide damping by means of a viscous silicone liquid 49, between them. Cylinder 52 also carries adjusting screws 53 whereby the density axis of the drum 26 can be brought into alignment with its rotational axis 50. As shown in Figs. 4 and 6, vanes 61, 62 are mounted on diametrically opposite portions of the drum 26 in spaces 60, 60a, between conducting plates 63, 63a and wall surfaces 64. The electrolyte in the spaces 60 affords a conducting path from the plate 63 through vanes 61, 62 and drum 26, to plate 63a. The drum 26 can therefore be used as an electrical pick-off with respect to the plates 63, 63a. The electrolyte filling the housing communicates through a channel 72 with a bellows 71 housed in a chamber 70 formed within the cup 46 to allow for expansion when the electrolyte becomes heated.

Title: Manufacture of iron compounds of the phosphorus-containing bodies of egg yolk proteids
IPC: C07K14/47
Filed: 1928-01-17
Abstract: 283,866. Posternak, S., and Posternak, T. Jan. 17, 1927, [Convention date]. Albuminoids.-The phosphorus-containing body a obtained from egg-yolk by the process described in Specification 268,806 is treated with an iron salt in calculated proportion whereby a product containing iron (not combined as a salt) is obtained which is almost indistinguishable from the phosphorus-containing body # described in the said Specification. The product thus obtained, and the body # contain two free phosphoric acid radicals and can therefore form normal and acid salts with iron or alkali or alkaline earth metals. The normal iron salts are produced bv reacting upon the product obtained from the body a as above described, or its mixture with the body #, with an excess of an iron salt in neutral solution, while the acid iron salt is obtained in the same manner but in strongly acid solution. Instead of the isolated bodies a or # there may be employed as starting material the crude product of pepsin and trypsin digestion of egg-yolk as described in Specification 268,805 to obtain a product containing iron " organically combined," (i.e., otherwise than as salt) or to obtain the normal or acid iron salts or the iron-alkali or ironalkaline earth salts of such body; and the body containing iron " organically combined " may be made by adding the necessary proportion of an iron salt to the egg-yolk and then subjecting it to the pepsin and trypsin digestions. In an example egg-yolk is digested as described above in presence of ferric chloride to obtain a mixture of the # and modified a bodies containing " organically combined " iron; it may be converted into alkali salts by dissolving in dilute sodium carbonate solution and precipitating with alcohol. In other examples egg-yolk digested as described in Example 1 of Specification 268,805 is treated with two proportions of ferric chloride to obtain iron salts containing 14.5 and 18 per cent of iron respectively. In other examples the phosphorus containing body a or a mixture of the bodies a and # are dissolved in weak sodium carbonate solution or very weak ammonia and treated under specified conditions with different proportions of ferric chloride to obtain iron compounds containing 5 per cent of " organically combined " iron, 14.5 per cent of iron, and 18 per cent of iron respectively; the first of these products may be dissolved in a small excess of ammonia and treated with calcium chloride whereby an ironcalcium compound is precipitated containing 4.5 per cent of iron and 10 per cent of calcium. All the products are intended for use in therapy.

Title: Improvements in or relating to stereophonic sound reproduction apparatus
Inventor: BROOK LEONARD
IPC: H04S7/00
Filed: 1959-01-17
Abstract: 943,791. Stereophonic systems ; monitoring two sets of signals. STEREOSOUND PRODUCTIONS Ltd. Jan. 18, 1960 [Jan. 17, 1959], No. 1797/59. Headings H4J and H4R. In a two-channel stereophonic sound reproduction apparatus, a visual indication of balance of the two channels is given by a magic eye or similar device. An internal audio signal generator AG feeds a signal of the same phase and amplitude into the two channels via volume controls VC. Tertiary windings T on output transformers TR are connected in parallel but in opposite phase, their common output operating a magic eye I after rectification by diode D. The point of balance, i.e. equal outputs from each channel and hence zero voltage across the parallel tertiary windings, is obtained by varying the volume controls VC until the eye is fully open. Suitable switching is included in the circuits to disconnect the signal generator and reconnect a pick-up PU, to disconnect the tertiary windings T from each other and from the visual indicator and to reconnect the loud-speakers, which are muted whilst balancing. A low wattage indicator lamp (Fig. 2, not shown), a neon lamp (Fig. 3, not shown), or a neon lamp connected directly between the anodes of the output valves (Fig. 4, not shown), may be used instead of the magic eye and the output transformer secondary windings may be used in place of the tertiary windings. An A.C. mains voltage may replace the signal generator.
