Title: Improvements relating to high-pressure centrifugal pumps
Inventor: SCHWENGLER WALTER
IPC: F04D29/04
Filed: 1960-09-08
Abstract: 885,018. Centrifugal pumps. KLEIN, SCHLANZLIN & BECKER A.G. Sept. 8, 1960, No. 30939/60. Class 110 (1). Axial thrust on the shaft 1, Fig. 1, of a centrifugal pump is relieved by means of a disc 5 and an auxiliary member 6 having a hollow cylindrical projection 7 which surrounds a cylindrical projection 3 on the disc 5. Ducts 4 in the disc 5 expose the rear surface of the member 6 to the liquid pressure acting on the rear surface of the disc 5. The disc 5 and member 6 are keyed to the shaft at 2 and 8 and their respective thrusts are transmitted to the shaft by means of thrust rings 11 and 12 located in annular grooves in the shaft. Sealing rings 9, 13 are provided. In the embodiment shown in Fig. 2, the auxiliary member 6 is located within a cylindrical opening at the back of the disc 5, and in this case the ducts 4 serve to expose the front surface of the member 6 to the liquid pressure acting on the front surface of the disc 5. As before, sealing rings 9, 13 and separate thrust rings 11, 12 are provided.
Patent GB-376147-A (GB)
Title: Improvements in and relating to the production of mixed fertilisers
IPC: C05C1/00
Filed: 1931-11-09
Abstract: A granular fertilizer is made by heating a mixture of solid ammonium nitrate and calcium carbonate to a temperature at which a part of the ammonium nitrate melts and allowing the melt to solidify on cooling rollers, worms, or the like.  The mixture may be heated in a vessel to which it is supplied continuously, while the melt is discharged through an overflow pipe.  A mixture of the ingredients suitable for treatment may be obtained by allowing a mixture of equivalent quantities of calcium nitrate, ammonia, carbonic acid and water to react in a solution of ammonium nitrate which was saturated in the cold state, but has been raised to a temperature of from 40-60 DEG C.  After reaction and cooling, a mixture of ammonium nitrate and calcium carbonate separates out and the mother liquor can be used again.

Title: Improvements in indicators for tea rolling machines
IPC: A23F3/12
Filed: 1929-10-14
Abstract: 331,784. Craig, W. G. Oct. 14, 1929. Tea, rolling.-An indicator is provided for tearolling machines to denote automatically when pressure is to be applied to or released from the leaf in the rollers. The indicator takes the form of an arroiv 10 mounted at one end of a laterally movable shaft 9 which also carries toothed wheels 7, 8, The shaft 1 is directly connected to, or geared to, the driving shaft of the rollers and a worm wheel 2 on the shaft 1 gears with a toothed wheel on the shaft 9 to rotate it. On the ends of a shaft 4 are spur wheels 5 and 6 engaging the toothed wheels 7, 8 alternately. The rotation of the shaft 9 by the interengagement of one of the pairs of wheels 5, 7 or 6, 8 causes a cam 11 to engage a fixed lug 14 to move the shaft 9 laterally to engage the appropriate pairs of wheels 5, 7 or 6, 8. In the form illustrated, the wheel 5 has two spurs and the wheel 6 one, and the cam 11 extends for half the circumference of the wheel 8. When the wheels 6, 8 are engaged, the shaft 9 rotates one tooth of the wheel 8 for each complete revolution of the shaft 4 until the pointer registers a position indicating the necessity for application or release of pressure. The cam 11 then causes the engagement of the wheels 5, 7. when the shaft 9 rotates two teeth of the wheel 7 for every complete revolution of the shaft 4, till the pointer registers the necessity for release or application of pressure.

Filed: 1927-11-21
Abstract: 289,726. Marks, E. C. R., (Monroe Auto Equipment Co.). Nov. 21, 1927, Fluid-friction vibration-dampers; pneumatic springs.-In an hydraulic vibration-damper which includes an air cushion, lever operating means, which include a rotatable bearing part, is inserted through a bearing opening in the body of the apparatus, the body being formed so as to retain the lever means in operative position in the bearing opening. The hydraulic apparatus is of the type in which a partition 4 separates a cylindrical portion from the main liquid chamber 2, this cylinder containing a piston 11 raised by a spring 12 and forced downwards by the short arm 25 of the lever member 25, 21, 29. A oneway ball valve 10 in the lower end of the cylinder ensures free upward movement of the piston 11 but checks its downward movement, escape of the liquid from the cylinder being then permitted only through the opening 13a, the size of which can be regulated by the screwed spindle 13. A shell 17 held down by the spring 12 contains air to cushion the movement of the piston and also forms a cage for the ball 10, tongues 15 being struck in from the walls for this purpose and also to leave openings 16 for the passage of liquid. The lever element comprises in addition to the short arm 25 a long operating arm 29, a main bearing portion 21, and a small bearing part 23. The part 28 is cut away to enable the lever element to be put into position through the bearing hole in the body. It is retained in position by engagement of the lever arm 25 with a projection on the inside of the body and can only be turned to close this projection for insertion or removal when the cap is removed.

Patent GB-637414-A (GB)
Title: Improvements in or relating to the distillation of synthetic alcohols
IPC: C07C29/74
Filed: 1947-11-28
Abstract: <PICT:0637414/III/1> Alcohols are recovered from hydrolysed acid extracts, obtained by absorbing olefins in sulphuric acid and then hydrolysing the esters so formed by addition of water, by distilling the extract in the presence of a small amount of an added hydrocarbon oil which is non-volatile at the temperature of distillation.  By this means the deposition of tarry and resinous polymers inside the still is prevented; for the polymers are dissolved or dispersed in the oil.  A C4 hydrocarbon fraction containing 15-80 per cent butenes is mixed with sulphuric acid in agitator 1 which is maintained at 25-50 DEG  C. by refrigeration coil 4.  Unreacted butenes and other hydrocarbons are removed from the extract in settler 7, and it is then mixed with water in mixer 11.  The mixture is passed at a slow rate through hydrolyser 12, and the hydrolysed extract withdrawn through line 13 is diluted with water from line 14 to an acid concentration of 45 per cent, and introduced into stripper 16 at about 75 DEG  C.  Steam is introduced into the base of the stripper and a non-volatile oil prepared from a naphthenic base crude, is supplied to the middle through line 19.  Butyl alcohol is taken off at the head of the stripper, and a mixture of dilute acid and oil is withdrawn from the base.  The mixture is passed to settler 22.  After decantation from the oil, the acid is passed to reconcentrator 24 where it is heated by indirect heat exchange with diphenyl or a mixture of diphenyl and diphenyl oxide.  The concentrated acid is then recycled to agitator 1.  The oil is preferably added continuously to the stripper at a rate of 0.05 per cent of that of the hydrolysed extract; but it may also be added periodically.

Rotary sieves.-Apparatus for screening coal, sand, gravel &c. consists of rollers 10, with spindle ends 11 arranged parallel to each other between the periphery of rotating rings 6, 7 mounted on a. shaft 1 and stationary rings 8, 9. The spindles are provided with bushes 12, preferably of resilient material such as rubber, composition &c., and carry pinions 13, 15 gearing with internally and externally toothed wheels 14, 16 mounted respectively on the rings 6, 7, and 8, 9. The shaft 1 is driven and the difference in the pitch circle diameter of the wheels 14, 16 causes the rollers to rotate about their own axes and also travel around the track between the rings 6, 7, and 8, 9. The spacing of the rollers may be varied by releasing the means for securing the pinions 15 and rolling the pinions 13 on the wheels 14, the excess or deficiency of rollers in the adjusted arrangement being corrected by removing or adding rollers. A hollow structure consisting of end plates 18, 18<1>, secured to the shaft, and carrying a series of scoop plates 19 may be provided to distribute, the material over the screen surface.
