Title: A method of and an apparatus for continuous saponification of vinyl ester polymers
IPC: C08F8/12
Filed: 1959-04-27
Abstract: Polyvinyl alcohol is continuously produced by adding a vinyl ester polymer in alcoholic solution to a saponification catalyst to initiate the saponification <PICT:0848787/IV(a)/1> reaction, continuously passing the reacting mixture without substantial agitation through a reaction zone, said reacting mixture passing through in piston-like flow, and continuously removing a continuous solid mass of polyvinyl alcohol.  The vinyl ester polymer is preferably polyvinyl acetate but the formate or propionate may also be used.  The saponification catalysts may be sodium hydroxide, potassium hydroxide, sodium methylate or sulphuric acid.  In a typical Example (No. 1), a 20,6% by weight solution of polyvinyl acetate in methanol was mixed in a mixer 1 with caustic soda solution.  The mixture flowed by gravity into a reactor 2 which is a vessel 100 cms in depth, and when the mixture reached a depth of 70 cms the mixture was withdrawn at a rate to maintain this depth, the solid polyvinyl alcohol being drawn from the reaction vessel by means of 2 pairs of rollers 3 and 4.

Patent GB-1354414-A (GB)
Title: Fluid-solid contacting chamber
IPC: C04B35/622
Filed: 1971-05-12
Abstract: 1354414 Non-woven fabrics; apparatus for making non-woven fabrics UNIVERSAL OIL PRODUCTS CO 12 May 1971 [13 May 1970] 14383/71 Headings D1K D1R D2A and D2B [Also in Division Bl] The fibre density of a woven or non-woven fibrous layer 7" of uniform thickness varies in the longitudinal direction. Preferably the density is constant for any transverse section. The density may vary smoothly and steadily in the longitudinal direction from the high density end to the low density end, an area of high density may be linked to an area of low density by an intermediate area of progressively changing density or the area of high density may comprise the middle of the layer. The layer may be in tubular form. The layer is used to control the flow of fluid. Thus in the inlet section 4" of chamber 1" the pressure exerted by liquid entering from conduit 2 is greatest at side 8 of fibrous layer 7". Hence an appropriate decrease in the density of layer 7" from side 8 to side 9 will produce a uniform flow of fluid through the fibrous layer. If inlet 11 is used the fibre density should be highest in the centre of layer 7". Alternatively layer 7" may have a density variation designed to produce non-uniform flow. The fibres may be impregnated with catalyst or may themselves act as catalyst and/or the layer may serve as a filter or molecular sieve. The fibres may be glass, aluminasilica, wool, cotton or synthetic polymer. In the embodiment of Fig. 2 a filament or yarn 20 is wound on rotating mandrel 28. A non-uniform density of the tubular product is obtained by varying the speed of guide means 20. The fibrous layer may comprise one to four woven layers in which the spacing of the warp (or weft) varies steadily (Fig. 3, not shown). In a further embodiment a loose layer of fibres (67, Figs. 4a, 4b, not shown) having more fibres at one end than the other is pressed to uniform thickness between two plates. A binder may be applied to the layer or the plates, if provided with perforations, may be used to maintain the integrity of the fibrous layer whilst it contacts the fluid flow. In a non-illustrated embodiment the fibrous layer is formed by air laying fibres onto a foraminous support to which a non-uniform pressure drop is applied. In the embodiment of Figure 5 a slurry of fibres is deposited by suction upon foraminous endless belt 99. Either the degree of porosity varies across the width of the belt or the top of the vacumn chamber 96 has perforations (110, Fig. 6, not shown) spaced at a greater distance apart at one end (111) than at the other end (112). The lip 92 of reservoir 91 is arranged so that more slurry is applied to the side of belt 99 to which the greater suction is applied. A mat of uniform thickness and variable density is thus produced.

Title: Improved automatic coupling for railway vehicles and the like
IPC: B61G3/16
Filed: 1929-05-09
Abstract: 333,284. Bogdanov, V. N. May 9, 1929. Automatic couplings; connectible to non-automatic; draw-gear.-An automatic coupling for railway &c. vehicles consists of two interengaging halves, each having two oppositely inclined surfaces which co-act with similar surfaces on the other half, locking-keys within inclined key-ways automatically locking the halves together. In action two lock members 3, one on each half, each loosely held by means of a tail-piece 7 within the coupling head 1, become centralized by the aid of inclined surfaces 8 and 9 and also by projections 13. On continued pressure between the vehicles, if there is any difference of level between the half couplings, the lower one is forced to slide up the other inclined surface Until the key-ways 10 and 11 are in alignment when keys 4 which had been pushed back into their respective holes, will then enter by their own weight, aided by springs 17 if such are fitted, thus locking the coupling. To disengage the coupling a chain 18 or the like attached to a key 4 is actuated, raising the latter from the opposing lock member. Provision is made in each lock member for enabling pneumatic, steam and electrical connections to be automatically connected and disconnected. One modification of the coupling adapts it for connection to an ordinary screw coupling, while in another the tail-piece of the head 1 is replaced by a back plate adapted for bolting to a buffer beam.

Title: Improvements in voltage control devices for electric supply systems
IPC: G05F1/607
Filed: 1938-05-17
Abstract: 514,835. Automatic control of electromotive force. WHITE, E. L. C. May 17, 1938, No. 14631. [Class 38 (iv)] In a voltage stabilizing system compensating for variations in the supply voltage and the load current, the positive terminals of the source of supply and of the load are directly connected, while the negative terminals are connected through a grid-controlled regulating valve acting as a variable impedance under the control of a controlling valve responding to the electromotive force across the load terminals. The positive terminals of the supply 5 and the load 6 are connected to one another and to earth, the negative terminals being connected through the regulating valve 11. The grid of this valve is negatively biassed and is connected to the cathode of the control valve 7 and thence to the positive terminals through a resistance 8. Battery 9 provides negative bias in the control valve 7. The arrangement is such that deviations from a predetermined value of the load 6 result in variations of the impedance of the regulating valve 11 tending to correct the deviation: Variations of the supply 5 above or below the usual value also vary the voltage difference between the cathode and the negatively biassed grid and result in variations in the impedance of the regulating valve tending to maintain the load at or near a constant value. In modifications, tetrodes or pentodes may be used and an additional battery may be arranged in series with the resistance 8. An additional controlling valve serving as an amplifier may be used, in which case only part of the voltage across the load may be applied to control the potential of the cathode of the controlling valve with respect to the grid. The source of negative bias 10 may be energized from an A.C. source and a rectifier.
