Title: A multiple-use root crop harvesting machine
IPC: A01D17/10
Filed: 1948-11-08
Abstract: 673,741. Endless conveyers; shoots and hoppers. NOLLE, J. Nov. 8, 1948. No. 28986/48. Classes 78 (i). [Also in Groups I and II] An endless riddling-conveyer for a root-crop harvester comprises endless chains 38 interconnected by cranked crossbars 201 which are freely pivoted between the chain links and are guided during their upward movement by guides 211 carrying rollers 218 or serrated surfaces 212 which impart a jigging motion to the cranked bars. The conveyer is carried by a frame 2 pivoted on a wheeled frame 1 about the axle 11 of the upper, driving, sprockets 209 ; the lower end of the conveyer, carrying the digging share 19, is supported adjustably by a lever and link system 65, 70, 73, from the wheeled frame 1 (see Group I) the system being arranged to work over-centre so that the conveyer is self-supporting in its raised position. In order to release earth entrapped between the conveyer runs, the lower guide member 213 includes loops and bends 243 which cause the cranked bars to separate in passing thereover. A cleaning roller 230 (Figs. 9 and 10) engages the cranked portion 210 of each conveyer bar and jerks it upwardly against the upper guide 211 thereby removing adherent dirt. The centre portions of alternate conveyer bars 203 are rubber-covered. The cleaned crop is delivered by guide members 22 into a hopper 100 rotatably mounted on a longitudinal axis 101 at the rear of the wheeled frame. The hopper is of triangular prismatic shape and is divided into three compartments by radial partitions. The hopper is locked in position by stops 121 engaging latches 104, 105. Rotation of a hand-lever 112 releases one latch and rotates a cam 111, which, by engaging the appropriate stop 121, tilts the hopper through 120 degrees to empty one compartment and re-position. an adjacent one.

Title: Improvements in or relating to the production of viscose for the manufacture of artificial fibres
Inventor: TORKE ERICH
IPC: D01F2/08
Filed: 1951-12-12
Abstract: Viscose containing more than 7 per cent. of a -cellulose and having a ratio of alkali content (as NaOH) to a -cellulose content of less than 1.0, for the production of artificial fibres, is prepared by alkalizing a cellulose pulp with a 16-26 per cent. aqueous caustic soda solution to produce an alkali cellulose having an a -cellulose content not in excess of 20 per cent., ageing the alkali cellulose, directly xanthating the aged alkali cellulose, and forming a fibre-free viscose having an alkali ratio of less than 1 within 40-90 minutes after the beginning of the xanthation by the addition of water and/or a dilute aqueous solution of caustic soda.  The alkalizing may be effected with the caustic soda solution and the cellulose pulp in such proportions that the caustic soda and a -cellulose contents of the mixture are those required in the alkali cellulose, no caustic soda solution being expelled from the mixture by pressing.  The xanthating of the aged alkali cellulose is carried out at about 20 DEG -40 DEG C., preferably 26 DEG -31 DEG C.  The proportion of carbon bisulphide used for the xanthating is less than 40 per cent., usually 30-35 per cent., based on the a -cellulose.  In an example 1 kg. sulphite pulp containing 88.5 per cent. a -cellulose is added to 15 litres of aqueous 240 g./l. sodium hydroxide solution at 35 DEG C. in an agitator and, after the excess of liquid has been expelled, the alkali cellulose paste obtained is pressed out to a weight of 4.9 kg.  The alkali cellulose which contains 19.3 per cent. of cellulose is shredded, aged for 17 hours at 34 DEG C. and xanthated in a churn with 270 c.c. of carbon bisulphide after cooling to 27 DEG C. After xanthating for 50 minutes with temperature rise to 31 DEG C., the xanthate is dissolved in 15 minutes by the addition of 5,360 c.c. of water at 10 DEG C. to produce a viscose containing 7 per cent. of caustic soda and 8 per cent. of a -cellulose.  When alkalizing without an excess of caustic soda solution a suitable wetting agent may be added, e.g. about 6 c.c. of sulphonated castor oil per kg. pulp, and the amount of caustic soda solution used may be about 3 to 4 times that of the pulp.

Title: Improvements in or relating to electric secondary clocks
IPC: G04C13/11
Filed: 1932-10-27
Abstract: 407,440. Electric clocks. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, MOORE, H. J., and WILMAN, C. W., Ericsson Telephone Works, Beeston, Nottingham. Oct. 27, 1932, No. 30128. [Class 139.] Combined with telephone sets.- An electric secondary clock is provided with means (lugs 18) so that it may be readily mounted in a telephone set in place of the automatic telephone dial. The clock mechanism is attached to a plate 14 which is mounted in the case 15 between rings 16, 17 of sponge rubber. The two lower lugs 18 on case 15 have pieces 19 for engagement with holes in the part of the telephone which normally receives the dial. Upper lug 18 has a tapped hole 20 for receiving a screw passing through another hole in the body of the telephone. Specification 178,936, [Class 40 (iv)], is referred to. The clock is driven by impulses of direct current applied in alternate directions at half-minute intervals to an electromagnet having two coils 1. The cores are joined at one end by a yoke 2 and at the other ends have magnetic extension pieces 3 supporting non-magnetic blocks 4 which bear pivots for the shaft 6. To the latter are attached, one each end and close to the magnetic extensions 3, two armatures 7 which are mounted 180‹ apart relatively to each other. A non-magnetic counter-weight 21 is mounted on shaft 6 close to each armature 7. Non-magnetic blocks 4 are joined by iron bars 8 to which are fastened two horse-shoe permanent magnets 9, like poles being in contact with the same bar. The inner surfaces of the bars are hollow to conform to the shape of armatures 7 and to give a very small air gap. When the electromagnet 1 is not energized the magnetic circuits of magnets 9 are completed by armatures 7, which latter therefore lie so as to bridge the bars 8. When magnet 1 is energized, unlike poles are induced in extensions 3 and armatures 7. Each armature is then attracted more strongly by one or the other of bars 8, and the shaft 6 turns 180‹. This shaft 6 therefore progresses in half revolutions and carries a worm 10 driving a wheel 11 which is frictionally attached to the minute hand arbor 12. Further to reduce noise the impulses of alternate polarity are fed from the master clock to the secondary through a circuit which includes a motordriven rheostat so that the time taken for the current to reach its maximum value is substantially longer than the time the clock takes to respond to the impulse.

Title: Improvements in and relating to the manufacture of titanium dioxide
Inventor: DEAR WILLIAM NOEL
IPC: C01G23/07
Filed: 1964-07-29
Abstract: In the production of TiO2 by vapour phase oxidation of TiCl4 in turbulent gas flow in an unobstructed tubular furnace, the TiCl4 is preheated in a refractory lined metal chamber having a plurality of internally heated elements projecting through the walls of the chamber. The heating elements may be in the form of tubes which have a closed end within the chamber or which pass through the chamber. They may be made of quartz or Al2O3, or Pt coated Ni alloy, and may be heated by means of electric radiant heaters, e.g. with SiC or Mo elements, or a hot fluid, e.g. combustion products of a fuel gas such as CO.  The preheating chamber may be made of steel or Ni alloy, and lined with SiO2, Al2O3, C, or a metal, e.g. Pt, and may contain inert granular material.  A seal of packed TiO2 or Al2O3 may be provided between the heating elements and the casing. The TiCl4 preferably flows at right angles to the elements.  The TiCl4 and oxidizing gas are separately preheated to such temperatures that, if no reaction occurred, the mixture would be at at least 700 DEG  C., preferably 850-1100 DEG  C.; the TiCl4 itself may be heated to 400-1100 DEG  C. The TiCl4 may be introduced into the oxidizing furnace downstream of the oxidizing gas and the downstream part should be cooled to below 500 DEG  C.  The oxidation process may be carried out as described in Specifications 1,049,282, 1,055,263, 1,069,071, 1,092,883 and 1,098,881. Thus, the parts of the furnace exposed to the Cl2 produced may be made of Al, Mg or their alloys, steel, Ni, or Ni alloys, and other parts made of Ni or Ni alloys, e.g. Ni-Cr.  Alternatively, the part upstream of the TiCl4 inlet may be refractory.  The furnace may be tapered in an upstream direction.  An inert particulate material, e.g. sand, may be injected into the furnace, and an inert gas, e.g. Cl2 or N2, may be introduced between the walls and inlets. AlCl3 and/or SiCl4 may be incorporated with the TiCl4 before preheating, and H2O vapour with the oxygen.
