Patent GB-585797-A (GB)
Title: Improved method for controlling the flow of fluids
IPC: B01J4/00
Filed: 1943-04-14
Abstract: <PICT:0585797/IV/1> In a process in which fluids are mixed in a chamber 7, an inert sealing liquid 8 is interposed between the inlet pipes 6, 17 and the reaction zone, and vessels 5, 16 are inserted in the inlet pipes so that should the flow of one of the incoming fluids fail, the sealing liquid will flow along the inlet pipe in question and into the appropriate vessel 5 or 16 to prevent dangerous backflow of the reagents.  The apparatus shown is applicable to the formation of butanechlorine mixtures wherein liquid chlorine flows in through a pipe 1 to a water coil vaporizer 2 and through the vessel 5 and a sulphuric acid seal 8 into the mixing chamber 7.  Liquid butane is fed by a pump 12 to a steam vaporizer 14 and through the vessel 16 and the seal 8 into the chamber 7.  A pump 10 circulates the fluids in the chamber 7 and the mixed gases are led off by a pipe 18 to an isomerization unit.  Failure in the flow of any of the incoming fluids will be detected by making frequent inspections of the level of the sulphuric acid in a gauge 9.  An automatic control may be employed to add sulphuric acid should the level thereof fall.  The use of a viscous sealing liquid and of narrow inlet tubes will slow down the rate of outflow of the sealing liquid.  Other sealing liquids which may be used are phosphoric acid, water, strong aqueous salt solutions and heavy mineral oils, and other processes mentioned are the chlorination of olefines and paraffins, e.g. ethylene dichloride, the formation of propylene glycol, and isomerizing light paraffin hydrocarbons to form branched chain products for incorporation in high octane motor fuels.  The Specification as open to inspection under Sect. 91 comprises also that the sealing liquid may be water or strong aqueous salt solution.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to bayer process
IPC: C01F7/148
Filed: 1964-02-14
Abstract: Alumina hydrate is precipitated from a pregnant caustic aluminate liquor containing oxalate (degraded organic material), which oxalate also precipitates and contaminates the alumina hydrate, and precipitated solids are separated from the major portion of the mother liquor for recycle as seed to the aforesaid precipitation, the seed being washed with water to dissolve the oxalate and the washed seed being separated from the oxalate-containing liquor and thereafter recycled to the precipitation process.  In Fig. 1, the contaminated alumina hydrate is fed to coarse particle-thickening system 10, from which the coarse particles are passed to washing apparatus 24 before calcination. The finer particles, separated by elutriation, are passed along with the major portion of the spent liquor to fine particle-thickening system 30, from which the overflow spent liquor is recycled to the digestion step and the underflow portion, containing the fine hydrate and solid oxalate, is passed to washing system 40 where it is washed with water at less than 32 DEG C. to remove caustic liquor and with water at 50 DEG  to 90 DEG  C. to dissolve the oxalate.  System 30 may comprise secondary and tertiary thickeners illustrated in Fig. 2 (not shown), in which case alumina seed of different sizes is obtained and washed by processes illustrated in Figs. 4 and 3 respectively (not shown). The seed is recycled and the oxalate liquor discarded or sent to system 50 wherein the oxalate is precipitated, e.g. by the addition of lime and the caustic solution produced is recycled to the digestion step, the calcium oxalate precipitate being rectified or calcined to regenerate time.  In other embodiments sodium oxalate is precipitated with strong caustic and converted to Na2CO3 or lead or barium oxalates are precipitated using the appropriate hydroxide. <PICT:1039985/C1/1>

Abstract: 1377561 Joints for artificial limbs A J HELFET 14 Feb 1973 [16 Feb 1972] 7079/72 Heading A5R A joint for an artificial bicondylar limb comprises a medial-lateral pintle 12 whose lateral end is articulated to the lateral walls of upper and lower limb elements 10, 11, by a common spherical ball 13 and socket pivot assembly 14, 15, and whose medial end 16 is journalled in the medial wall of one limb element 10b and has a non-slip rolling engagement means 18 with an edge 21 of a slot 19 in the medial wall of the other limb element 11b, both elements being coupled to the pintle 12 through respective torsional restraint or torque control coupling units 23, 24. In a knee joint, a cam or wheel 18 rolls in contact with the edge 21 by means of teeth (20) Fig. 2 (not shown) and in sliding contact with upper edge 22 of the slot 19 which may be lined with P.T.F.E. The pintle 12 is coupled to the artificial femur 10 and fibia 11 through respective restraint or torque control units 23, 24, each of which transmits to the pintle (or vice versa) a torque up to a pre-determined maximum which is dependent on the angle of the axis of the slot 19 relative to the axis of the tibia 11  and the contour of edge 21. In a modification Fig. 3 (not shown), a modified pintle (32) has a plain journal bearing (36) in the medial wall 11b of the tibia 11 and a spherical socket (34) embracing a ball (33) locked by the stem (37) in the adjacent lateral wall 10a of the femur 10. The tibial lateral wall 11a has a pivotal bearing socket (35) on the external surface of the pintle socket (34). The cam or wheel 18 is mounted on the medial extremity of the pintle (32) outside the plain journal (36) and engages the upper edge 22 of the slot 19 formed in the medial wall 10b of the femur. The restraint and torque control couplings. 23, 24, can vary in their characteristics to allow free forward swing or to facilitate sitting with the knee bent. A detent device (40, 43) Fig. 3 mounted in the femur is inoperative in normal operation, but is lockable with the tibia at the higher velocities associated with stumbling. Alternatively, signals from implanted sensers in the stump can be amplified to operate a servo motor and lock the joint in response to a natural reflex action.
