Abstract: 928,349. Turbine or compressor blade fixing. ROLLS-ROYCE Ltd. Nov. 23, 1961 [Dec. 6, 1960], No. 42046/60. Class 110 (3). A bladed rotor of a gas-turbine or like machine comprises a ring of blades mounted at the periphery of a rotor disc or drum and an annular plate which lies against axially-facing surfaces of the periphery of the disc and of the root portions of the blades and is located in position by a key. A gas-turbine blade 12 having a root 12a has a shoulder portion engaging a correspondingly shouldered channel 17 extending across the rim 11a of the rotor disc 11. An unsplit annular plate 16 is mounted on either side of the disc 11. Each plate 16 comprises a main portion 16a which tapers radially outwards from a circumferential land 16c to a circumferential lip 16b at its outer edge. The outer surface 16d of the land 16c engages the surface 11b formed by an annular groove 11c on the disc rim 11a. The inner edge of the plate 16 is provided with groups of angularly spaced, inwardly projecting dogs 18 which engage behind outwardly projecting dogs 19 on the disc rim 11a when the plate is in position. One or more larger spaces 20 are provided around the plate 16 between each group of dogs 18. Keys 21 locate the plate with respect to the disc 11, there being an equal number of keys as spaces 20. The inner surface 21a of each key bears on the lower surface 11d of the groove 11c and the outer surface 21b bears against the surface 16e of the land 16c on the plate 16, thus locating the plate 16 against radial movement. A tab 21f on each key abuts the adjacent circumferentially facing surfaces of the two dogs 19 behind which the ends of the key are engaged. The tab 21f is bent upwardly to engage a radial notch 16f in the plate 16 and locate the plate circumferentially. Where a plate 16 has a continuous lip 16b, the ring of blades 12 is provided at the outer ends of their roots with undercut flanges 12c to receive the lip 16b. In this case the other plate 16 will have a series of outwardly extending dogs 116b at its outer edge to engage behind corresponding dogs on alternate blade roots 12a, or will have a radial extent insufficient to reach the outer limit of the blade roots 12a. In a modification, both plates 16 have a dog formation at their outer edges. The plates 16 may be provided with holes to admit, or to allow the escape of, cooling air.

Title: Method of recovering glutamic acid valves
IPC: C12P21/00
Filed: 1964-10-20
Abstract: Glutamic acid may be obtained in the form of its basic calcium salt from an unhydrolysed fermentation liquor by adding thereto at an elevated temperature Ca ++ ions in an amount at least equivalent to the glutamic acid present, filtering off undissolved matter at a temperature at which basic calcium glutamate remains dissolved and thereafter precipitating basic calcium glutamate from the resulting filtrate. Precipitation may be achieved by admixture with a water-miscible aliphatic alcohol or by concentration under reduced pressure.  The Ca ++ ions may be provided by slaked lime or quicklime.  The basic calcium glutamate may be re-dissolved in water at a temperature of above 50 DEG  C., filtered and recrystallized by gradual cooling.  The basic calcium glutamate may be subsequently converted to sodium glutamate by passage through a chelate resin or cation exchange resin in the sodium form, or by treatment with CO2 or H2SO4 in the presence of a sodium salt.  Residual calcium ions may be removed from the sodium glutamate by using oxalic acid.

Title: Improvements in digital information transfer system
IPC: H04Q9/14
Filed: 1969-08-27
Abstract: 1,274,110. Electric selective signalling; data transmission. GENERAL ELECTRIC CO. 27 Aug., 1969 [3 Sept., 1968], No. 42742/69. Heading G4H. A system for transmitting digital data from a number of remote stations to a central station includes, in the central station, a device for sequentially interrogating the remote stations and in the remote stations a control device which, on receipt of a command signal from the central station, scans the digital data, transmits it to the central station and generates a signal signifying the end of the transmission which, when received at the central station, causes the next remote station in the sequence to be interrogated. In an embodiment the data in each remote station is divided into three groups which are scanned sequentially. The remote stations receive a signal from the central station which consists of a remote station address and a number of command, sync., and parity bits. The correct station responds by energizing its control device which causes the first group of data to be scanned under the control of a counter. When the first group of data has been scanned the control device emits signals consisting of a word signifying the end of the first data group transmission, the complement of the station address and a parity character. The control device then initiates the second data group scan and on completion emits a word to that effect. The final data group consists of a number of two state devices which are only scanned if any of them have undergone an unauthorized change since the last scan. The control then emits a word signifying the completion of the transmission. The central station includes a number of data display units e.g. printers or C.R.T.'s which are sequentially energized in synchronism with the remote station scan. The data is handled in the central and remote stations in parallel form and is transmitted in serial form. A three position switch is provided at the central station to modify the command emitted to allow the first data group only or the first and second groups only or all three to be scanned. All transmission include sync. and parity bits to enable the central and remote stations to remain in synchronism and to detect faults.
