Title: Quartz fibres and extruded rods
IPC: C03B37/065
Filed: 1962-07-30
Abstract: <PICT:1010702/C1/1> A method of forming quartz fibres, comprises mixing together powdered silica, a liquid binder composition comprising from 1 to 50 weight per cent of a binding agent, and an extruding agent, extruding the mixture into a self-sustaining rod, drying the extruded rod, and passing the rod into a fibre-forming torch having an operating temperature above the melting point of the silica thereby forming the quartz fibres, the temperature prior to the fibre-forming step being maintained below the melting point of the silica.  Quartz powder with a binder and extruding agent added is slowly extruded out of an extruder 14, by an hydraulically operated piston 16, through a die 24.  The resulting rod 26 passes on to a synchronized wire conveyer belt 28 on which it is dried by bunsen burners 30, 32.  The rod 26 then passes through a guide 34 and between rollers 36, 38 into a fibre-forming torch 40. Suitable extruding agents and binding agents, and liquid solvents or suspending agents therefor, are described.  Of the binding agents mentioned polyvinyl alcohol, if present in sufficient quantity, may also act as an extruding agent.  Several alternative means for drying the rod 26 are mentioned.  Slight additions of other materials which could form glassy substances, e.g. boron trioxide, may be employed.

Abstract: 843,023. Road vehicle couplings. DAVIES MAGNET WORKS Ltd., and DAVIES, P. M. Aug. 25, 1958 [Sept. 17, 1957], No. 29320/57. Class 103(5). A fifth wheel coupling comprises a guide bed 1 bolted to the tractor, a sub frame 2 rotatably supported on the bed by rollers 11 and a central bearing 8, a plate 3 pivoted to the frame 2 on transverse bearings 2b and having jaws 3a receiving a king pin 4 on the trailer, locking pins 19 for locking the frame 2 and the bed 1 together, and a second locking device 27 engageable with the sides 27a of a Vee cut in the plate 3 to lock the frame 2 to the trailer, the arrangement being such that when the second lock 27 is operated by backing the tractor during coupling the locking pins 19 are withdrawn from holes 21 in the bed 1 so that the trailer and frame 2 may together swing with respect to the bed and the tractor about an axis 5 through the bearing 8 or the trailer alone may swing about the axis 5a of the king pin 4. In either case however the load transferred from the trailer to the tractor is spread over the area of the bed 1. The pins 19 are biased to the locking position by a spring plunger 14 acting on rocker arms 13. In addition to the king pin the trailer is provided with a plate 6 from which may depend a retractable member 27 so that during coupling the member 27 may be engaged with the sides 27a of the Vee cut in the plate 3 and push forward a'link 24 pivoted to the rocker arms, thus raising the pins 19 and permitting relative movement between the tractor and trailer to take place about either of the axes 5, 5a. As an alternative or in addition to limit stops 11b<SP>1</SP> and 11c cable operated friction surfaces between the frame 2 and the bed 1 are provided to brake the rotation of the frame 2. If however the lock member 27 remains retracted during coupling then the frame 2 will stay locked to the bed 1 and the coupling will operate as a normal fifth wheel coupling. Various other embodiments of the two locking arrangements are also described, including a modification wherein the member 27 may be pivoted downwardly to engage the surfaces 27a and the sub frame locking member by means of a pivoted shaft which may be dog clutched into or out of the operative position.

Patent GB-893971-A (GB)
Title: Separation of carbon dioxide from gaseous mixtures
IPC: B01D53/62
Filed: 1959-09-01
Abstract: <PICT:0893971/III/1> CO2 is recovered from gaseous mixtures containing it together with H2, N2, O2, CO, H2S, hydrocarbons, moisture and air by absorption at superatmospheric pressure in a countercurrent stream of glycerol triacetate, reduction of the pressure to flash off the CO2 and subsequent recycling of the lean triacetate solution for further CO2 absorption.  A gaseous mixture containing CO2 under a partial pressure of CO2 of 40-600 p.s.i.a., preferably 60-600 p.s.i.a., and a temperature of 30 DEG -130 DEG F., preferably 70 DEG -120 DEG F., enters the base of a packed or tray-filled absorption tower 11 through line 10 and flows in counter-current to a descending stream of glycerol triacetate cycling in the system and entering the tower through line 12.  Undissolved gases are vented through line 13 to a suitable receiver 14.  Rich triacetate solution containing absorbed CO2 leaves the base of the absorption tower through line 15 and passes either directly through line 15, valve 17 and line 15a to flash-off chamber 18 or indirectly through cooler 16 which removes the excess heat of solution. Solution passing through valve 17, which may be a turbine, into chamber 18 undergoes controlled pressure reduction, usually to atmospheric pressure, to effect dissolution of absorbed CO2 which is vented through 19.  Lean triacetate solution may by recycled direct to the absorption tower by pump 20 through lines 21 and 12 or some or all may be subjected to gas stripping in tower 23 to remove final traces of absorbed CO2.  Tower 23 receives stripping gas, e.g. air or inert gases, through line 24 usually at the rate of 1-4 SCF/gallon of triacetate solution, and vents stripping gas and desorbed CO2 through an overhead line, triacetate solution passing out through line 25 back to the absorption tower.  Stripping of final traces of absorbed CO2 may also be effected by application of a vacuum in tower 23. Moisture absorbed by the rich triacetate solution from the feed gas will be flashed off with the CO2.  In a modification of the above process (not shown) wherein CO2 is removed from gases comprising hydrocarbons which normally cause problems by solution in the glycerol triacetate, the rich triacetate solution is removed from the absorption zone of the tower and passed into a lower medium pressure flash-off chamber forming the bottom of the tower, where the pressure is reduced to between that existing in the absorption zone and the vapour pressure of the CO2 in the rich triacetate solution at the temperature of operation. Flash-off gas comprising mainly hydrocarbon is removed from the chamber and may be compressed and coded and recycled to the absorption tower for recovery with the other undissolved gas or be used independently as a fuel.  The remaining partially regenerated solution is passed to the final flash-off chamber 18 as before.
