Title: Expansible sheet metal casing for the production of concrete piles or pillars
IPC: E02D5/66
Filed: 1939-07-10
Abstract: 531,021. Concrete piles. HORNLIMANN, F. July 10, 1939, No. 19993. [Class 68 (ii)] Concrete piles are cast in a sheet metal casing which, where introduced into the ground, is in the form of an elongated rectangle and is then expanded by internal fluid pressure to form a container for the concrete. The casings may be closed at their ends by folding members which allow expansion. Flat tubes 1, shown for example in Fig. 1, may be given a sinuous form, as shown in Fig. 14, before being driven into the ground. Very little headroom is required, the flat tube 1 being led, as shown in Fig. 15, over a guide roller 10 and between sets of cooperating rollers 11 of increasing depth by which it is made sufficiently compact to enter tube 5. When tube 5 is withdrawn the tube 1 may be expanded by internal pressure until it is approximately circular. The tube 1 may be made with the long sides further apart or it may be deformed to present internal cavities or external recesses to accommodate devices for use in sinking the casing as shown for example in Figs. 7 and 11. Various other ways of deforming the flat tube 1 before or while it is entering the ground are described.

Patent GB-1087045-A (GB)
Title: Elastic polypropylene yarn and process for the production thereof
IPC: C08K5/43
Filed: 1965-05-13
Abstract: Elastic filaments are made by melt-spinning under conditions to produce "gamma orientation" a stereoregular polypropylene to which has been added 0.1 to 0.8 mole of an azido cross-linking agent per mole of polypropylene and heat-treating the filaments thereby formed at 105 DEG  to 160 DEG  C. in the relaxed state.  The polymer containing the azido cross-linking agent is subjected before or during extrusion from a spinneret to a temperature above 100 DEG  C. "Gamma orientation" is defined as meaning an orientation of the molecules of the filament in a direction or in a plane not parallel to the axis of the filament.  The spinning of the polymer is conducted under conditions which produce the characteristic property referred to in Specification 935,809 as gamma orientation. Such orientation is produced during the melt draw down of the polymer, its magnitude depending upon the viscosity of the polymer and the amount of such melt draw down. By melt draw down is meant a permanent elongation of the filament in the molten state prior to any solidification of the filaments as they leave the spinneret.  The polymer containing the azide compound is extruded at a temperature sufficiently high to cause the azide to react with the polypropylene. The polymer containing the azide may be extruded at 260 DEG  to 310 DEG  C. to form filaments which are melt drawn at a melt draw ratio between 10 and 100: 1, and heat treated at 140 DEG  to 155 DEG  C. in the relaxed state for a minimum period of about 2 minutes.  The azido cross-linking agent may be a sulphonazide having the formula R(SO2N3)x or an azido-formate having the formula <FORM:1087045/C3/1> In both formulae R is an organic hydrocarbon radical inert to polypropylene and x is an integer from 2 to 8.

Title: An improved apparatus for the continuous testing of gas mixtures
IPC: G01N11/08
Filed: 1920-07-10
Abstract: 148,764. Marks, E. C. R., (Union Apparatebau-Ges.). July 10, 1920. Gas analysis.-An apparatus for the continuous testing of gas mixtures comprises a capillary K<1> and a nozzle D<1> through which the gases are drawn in succession, and a manometer N<1>, M<1> for recording the variations in pressure consequent on the change in composition of the gas, arranged intermediately between these two members. The gases enter through a filter F<1>, and are withdrawn at the point c, the pressure at this point being controlled by the device U. To compensate for variations in pressure of the gases to be tested, for instance, flue gases, a subsidiary apparatus comprising suitably-proportioned resistances W<1>, W<2> is provided; this apparatus is open to the air and is connected to the inlet end at the capillary K<1>, and a manometer h connected intermediately of the two resistances serves to counterbalance the variation in pressure at the manometer N<1>, M<1> due to change in pressure at the inlet a; the manometer h forms a part of the compensating float S<2>. To compensate for variations in temperature a second apparatus K<2>, D<2> is provided, exhausting into the outlet c and supplied with air through a filter F<2> built into the filter F'; the pressure obtaining between the two elements of this' apparatus actuates a manometer N<2>, M<2>, the float S<2> of which is interconnected with the float S' so that changes of pressure due to variations in temperature have no effect on the stylus s; this arrangement also compensates for variations in the actuating vacuum at the point c. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement in which the manometer b is incorporated in the record ing-float S'. This subject-matter does not appear in the Specification as accepted.

Abstract: 460,081. Pneumatic classifiers. NEWELL & CO., Ltd., E., MOSS, A. H., and KELLINGTON, N. A. July 25, 1936, No. 20614. [Class 23] In a pneumatic classifier the entering stream passes downwards beneath the end of a sleeve, then upwards to openings between adjustable vanes in the upper part of a cyclone separator. The outer casing 10 has a rising inlet 12, and the top supports a telescopic sleeve 13, 14. Inside this sleeve is supported a wall 17 enclosing a chamber 18 the upper part being cylindrical and the lower part being conical. The cylindrical part has a number of ports 20 which are controlled by flaps 21 secured to spindles 22 the upper ends of which carry sprockets 24. These are engaged by an endless roller chain 25 which also engages a sprocket on a hand wheel by which all the flaps can be operated to vary the angles of the flaps and consequently the whirling of the gas stream. The adjustable part 14 of the telescopic sleeve is adjusted by means of screwed spindles 30 which are raised or lowered bv the rotation of nuts 31 operated by a chain 34 from a hand wheel. The stream enters the rising inlet 12 and flows round the edge of the sleeve 14, and the coarser particles are thrown out to drop to the discharge opening 11. The stream then passes through the ports 20 and rotates in the chamber 17. The finer particles are rejected in this chamber and the clean gas passes through the outlet 16. The finer particles may be collected by a conduit connected to the opening 19.

Title: Process and apparatus for distillation
Inventor: MITCHELL CHARLES DUNCAN
IPC: C08F2/00
Filed: 1954-07-15
Abstract: <PICT:0802148/III/1> Residual monomers are stripped from crude polymers by mixing the crude polymer with steam in a vessel under reduced pressure, and conducting the mixture to the top of a distillation column, under reduced pressure, down which the polymer flows in countercurrent to more steam.  Butadiene and styrene may be stripped from crude latex formed by their copolymerization in an aqueous medium.  The latex, introduced by a pipe 5, is mixed with steam, introduced by a pipe 7, in a vessel 4 connected by a pipe 9 to a distillation column 11 under reduced pressure.  The latex foam formed in vessel 4 is sucked into the column 11 through a T-piece 17 and the foam is broken by impact on the side of the column, the latex falling on to an imperforate top plate 14.  During residence time of the latex above top plate 14, disengagement of steam and vaporization of styrene and butadiene occurs.  This distillate passes through a pipe 22 and a condenser 23 to vessels 25 and 28, where the water layer is separated from the styrene.  Butadiene vapour is removed through pipe 30, to which a pump is connected to evacuate the apparatus.  Latex passes through a U-shaped downcomer 13, and then through a series of perforated plates 12, each provided with U-shaped downcomers, to a reservoir 18.  More steam is introduced through a pipe 20 to remove monomers remaining in the latex.  This steam causes further foaming and some of the latex is carried back up the column with the distillate, passing up a pipe 16 to meet incoming latex foam, whereupon all the foam is broken and the latex carried up pipe 16 is returned down the column.  Two forms of the T-piece are described, together with a lay-out of a plant for stripping styrene and butadiene from crude polymer using a modified distillation column.
