Title: Improvements in or relating to sugar beet extraction
IPC: C13B10/10
Filed: 1953-01-05
Abstract: 782,651. Extracting sugar beet. HEINRICH, K. Jan. 5, 1953 [Jan. 3, 1952; March 5, 1952; July 29, 1952; Dec. 17, 1952], No. 271/53. Class 127. The countercurrent extraction by liquid of sugar from sugar beet in a diffusion tower involves introducing a plasmolized mash of the beet cossettes into the lower part of the tower, immediately above a sieve therein, as a layer of uniform depth from the trailing edge of a rotating mash distributer at a pressure above the hydrostatic pressure at the point of entry but below the pressure at which the introduced layer would break through superposed layers of mash already introduced, to cause the mash to ascend the tower in a uniform continuous spiral, stirring the layers of mask by stationary and/or rotating radial vanes in the tower to ensure thorough contact of the ascending mash and descending extraction liquid, and cleaning of the sieve by the leading edge of the mash distributer as it rotates. The apparatus of Figs. 3, 7, 9, 10, 18 and 19 comprises a cylindrical diffusion tower a in which is a rotatable concentric tube b, a sieve e across the lower part of the tower, a mash distributer d, rotatable with the tube b, having on its leading edge a pivoted shoe which bears upon the sieve and so cleans the sieve on rotation of the distributer and having along its trailing edge a cavity with a pivoted flap control 2 for even deposition of a layer of mash upon the sieve on rotation of the distributer, a number of rods 90 fixed on the tower walls and extending radially inwards, a number of radially disposed arms 91 extending from the tube b and rotatable therewith to cause turbulence in the mash-liquid layers, and a device il, rotatable with the tube b, for ejection of extracted cossettes layer by layer through an opening m below a screen n at the upper end of the tower. The cossette mash is supplied by a pipe c to the mash distributer d. Water supplied by a pipe g is distributed in the tower through perforations in radial pipes h. Juice is led from the tower by a pipe s. When the apparatus is used in conjunction with that of Specification 782,652, hot mash introduced to the tower by the pipe c is taken from the apparatus of Specification 782,652 by a pump 100 and the juice leaving the tower by the pipe s is returned by a pipe j to the apparatus of Specification 782,652.

Patent GB-1021613-A (GB)
Title: Production of bromine
Inventor: BIET ALFRED G P
IPC: C01B7/09
Filed: 1964-01-08
Abstract: <PICT:1021613/C1/1> Bromine is prepared from hydrobromic acid or mixtures containing it by oxidation with nitric acid or nitrogen oxides, such as those obtained by the combustion of ammonia, in a solution of acidity at least 5N.  The hydrobromic acid-containing mixture may be that obtained in the recovery of bromine from sea water by treatment of brominated air with sulphur dioxide and spray water and consists of a mixture of HBr and H2SO4, referred to in the Specification as "bromosulphuric acid." Bromo-sulphuric acid containing 50-250 g. HBr per litre is fed via line 1 (see drawing) to packed column 2 and thence to reaction zone 3 supplied with nitric acid, e.g. 50-70% concentration, through line 4 and make-up mineral acid to achieve the required acidity through line 5.  The reaction solution is maintained, preferably under atmospheric pressure, at between room temperature and the boiling point of bromine by inserting cooling means between reactor 3 and column 2, or the bromosulphuric acid may be pre-cooled to below room temperature. When the bromosulphuric acid concentration is 70-100 g. per litre, or the make-up acid is sulphuric acid of low concentration, or is hydrochloric acid, heat is required to promote the reaction. Sulphuric acid in the reaction solution is preferably 20 to 36% by weight. Bromine formed flows through line 7 to packed column 8 maintained at near room temperature and air or oxygen entering via 9 carries away entrained nitrosyl bromide via pipe 10 to the bottom of column 2.  The bulk of the NoBr produced in reactor 3, plus that arriving via pipe 10, plus air or oxygen introduced via line 6, ascends column 2 and, in contact with descending bromosulphuric acid, is converted to nitric and hydrobromic acids which return to the reactor 3.  Residual acid from reactor 3 passes via line 12 to packed column 13 into which steam and optionally air or other inert gas is passed via line 14. Dissolved bromine is thereby returned to reactor 3 via line 15. Bromine-free residual acid leaves via line 16, gases via 17 and bromine via line 11.

Title: Improvements in arrangements of grid controlled gas or metal vapour discharge devices which can work as rectifiers and as inverters
IPC: H02M7/00
Filed: 1933-01-10
Abstract: 413,292. Converting. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Jan. 10, 1933, No. 880. Convention date, Jan. 26, 1932. [Class 38 (ii).] Relates to rectifier and inverter arrangements provided with grid controlled discharge devices and having smoothing-devices in the D.C. circuit and consists in providing an auxiliary discharge path for the energy stored in the smoothing-devices so that this energy does not pass through the transformer, thus improving the power factor at which the arrangement operates. In the form shown in Fig. 3, the D.C. and A.C. circuits are interconnected through a discharge device 3 and an auxiliary valve 5 is connected between the centre point of the transformer secondary supplying the anodes and the cathode. Previously the energy stored in the choke has prolonged the burning period of an anode after the A.C. potential applied to it has passed through zero. This energy now passes through the auxiliary valve 5 and the transformer is relieved of out-of-phase current. In a modification, Fig. 4, in which a discharge device 8 is supplied from two three phase windings interconnected through an inter-phase choke 9, auxiliary anodes 12, 13 are provided which are connected to the ends of the choke 9. For inverter operation the auxiliary anode paths are grid controlled. To avoid back ignition during rectifier operation it is preferable to control the auxiliary anodes by grids.

Abstract: 1,208,013. Stuffer-box crimping yarn. KLINGER MFG. CO. Ltd. 3 Jan., 1968 [6 Jan., 1967], No. 892/67. Heading D1F. A plug of crimped yarn is conveyed through a treating zone with the aid of a flow of gas sucked therethrough. The zone is formed by a tube positioned at the exit of a stuffer box of the type in which a plug of crimped yarn is conveyed through an arcuate setting zone by a toothed wheel. The tube which is of larger diameter than the plug and may increase in diameter towards the outlet may be vertical with a curved upper portion, horizontal, or J- or U-shaped. Cool air may be sucked through the tube to cool the yarn, or hot air may flow through the first portion of the tube and cool air through the second portion. Alternatively or in addition the tube or part thereof may be heated to modify the crimp characteristics. The tube may be of, or have windows of, glass or a transparent plastic material with a photocell arrangement to control the withdrawal rate of the yarn from the tube by the winding means so that the plug of yarn is accumulated within prescribed limits. In the event of tube becoming overfilled it is arranged to pivot to operate the micro-switch of a stop-motion. Moisturing and finishing agents may be applied to the yarn in the tube.

Title: Improvements in slow-down devices for registering sheets in sheet-feeding machines
IPC: B65H9/14
Filed: 1921-01-08
Abstract: 157,100. Christophel, C. E. Nov. 10, 1919, [Convention date]. Sheet-registering devices. - Automatic sheetfeeding machines are fitted with slowing-down devices, which also straighten the sheets prior to their being fed to front stops or the like, the devices comprising gauges mounted on reciprocating carriages moving on laterally spaced track-bars at a speed which is less than that of the sheet-forwarding mechanism. Two or more movable gauges 30 are mounted on carriages 21 reciprocated along track-bars 22 by means of oscillating arms 18, and connecting-rods 19, the arms 18 being on a transversely mounted shaft 14 oscillated bv cam-mechanism. The actual gauges 30 are flanges on a plate 29 secured to an arm 27 mounted on a pivot 20 and formed with a cam-arm 31 and roller 32 for controlling the position of the gauges. As the carriage 21 moves to the left in Fig. 2, the roller 32 engages an inclined cam surface 25<1> on a leaf spring 25 secured in a recess 23 in the bar 22 and is depressed thereby and by a corresponding incline on a guide-bar 26, so that the gauge engages an advancing sheet, and slows it down. As the several gauges move in unison, the sheet is eventually straightened by the action of the gauges. When the roller 32 reaches the end of the bar 26, it is raised by a spring 32<1> acting on a lever arm on shaft 20, and on the return motion it rides on the bar 26, the gauge being then above the sheet. During this return, the roller 32 presses on the spring 25 and forces it against the side of the recess 23.

Patent JP-S61172105-A (JP)
Title: Optical radiator
Inventor: MORI TAKASHI
IPC: F21S11/00
Filed: 1986-01-06
Abstract: PURPOSE:To radiate light propagated in a cylindrical optical conductor outside the conductor through a groove part by providing plural grooves engraved spirally on the surface of the cylindrical optical conductor. CONSTITUTION:Some part of the light beams propagated through the optical conductor in parallel with said conductor is reflected on the groove part and emitted outside said conductor, while remainders are propagated downward. In the same manner the light beam reflected on each groove part is emitted outside the optical conductor. Since the light beam propagated in the optical conductor is flux, it is diffused effectively from each groove part in each direction and emitted. However, as going downward, the flux density in the optical conductor is reduced, and the light quantity emitted from the optical conductor is decreased. Accordingly, when the light beam is uniformly emitted from the all surfaces of the optical conductor, the groove density is increased along the light advancing direction, or the groove is made deeper. If the light beam need not be emitted from the downward end surface 1a of the optical conductor 1, a reflecting mirror is installed on said surface, and even the reflected light beam is emitted through the groove part.
