Abstract: A thin layer chromatographic element comprises a flexible support bearing a layer containing a chromatographically active adsorbent and a polymeric binder, the weight of the binder being from 2-65% of the total weight of the adsorbent and binder, the binder causing the adsorbent to adhere to the support while permitting access of an elutant to the absorbent when the element is in use.  The support may be dimensionally stable polyester films such as polyethylene, terephthalate, polyvinyl, polyolefin, cellulose or polyamide films, metal foils such as aluminium foil. Suitable adsorbents are alumina, silica gels, diatomaceous earth, titanium dioxide, kieselguhr, polyamide powders, ion exchange resins and cellulose.  The polymeric binders may be: hydrophilic polymers such as polyvinyl alcohol, gelatin-polyvinyl alcohol mixtures, gelatin derivatives; cellulose derivatives such as carboxymethylhydroxyethyl cellulose; thermosetting polymers such as melamine-formaldehyde, polyvinyl formal, acetal, butyral, ureaformaldehyde, polyisocyanate, polyhydroxy ether, epoxy and other cross-linking resins and mixtures thereof; polyolefine resins such as polyethylene and polypropylene in emulsion and non-emulsion form.  A sub-layer may be provided on the support e.g. a layer of a terpolymer of methyl acrylate, vinylidene chloride, and itaconic acid.  Where polyvinyl alcohol is used as binder, the support may be first treated with a solution of trichloroacetic acid.  Phosphor or fluorescing compounds may be present, and also silver nitrate incorporated by dipping the element into alcoholic silver nitrate solution and then drying the element. Any conventional coating method may be used e.g. doctor blades, air knives, roll coating, hopper coating.  A solution of the polymeric binder in a solvent e.g. water, ethanol-water mixtures, containing the adsorbent in powder form may be coated on the support.  A reticulating agent may be added to the polymer solution before coating so that the polymer becomes insoluble after coating and before use; e.g. a solution of polyvinyl butyral and urea-formaldehyde resin modified by aliphatic alcohols in methyl isobutyl ketone.  The elements may be activated by heating before use.

Abstract: 303,195. English Electric Co., Ltd., Pooley, A. M., and Heath, A. A. Sept. 29, 1927. Fastenings for hinged doors.-Covers and lids of switch, fuse and other casings are interlocked so that two adjacent doors cannot be opened simultaneously by hingeing the doors on opposite sides and interconecting the edges of the doors remote from the hinges by means of a link pivoted to each door about an axis which when the door is closed is in line with the hinge of the other. A movable member is also carried by one door in such a manner that it engages the other door if the doors are opened in an undesired sequence, the other door having to be opened first to permit the release of this member. As shown in Figs. 1 and 2, three castings 2, 3, 4 are arranged side by side, the outer pair of casings containing isolating switches 21 which should be opened first before access is obtained to the fuse 12 in the centre casing. The doors 9, 11 of their outer casings are hinged at their lower sides 13, 14, the centre door being hinged at its upper side 15 and Z-shaped members 16, 17 interconnect the free ends of the doors to prevent the centre door being opened at the same time as either of the outer doors. The centre door also carries pivotally on its inner side members 18, 19 connected by a spring 20 so that if an attempt is made to open this door before the outer ones have been previously opened and closed, one or both of these members engage the inner sides of the adjacent doors, preventing the inner door from being opened. If, however, the outer doors are previously opened and the members 18, 19 drawn aside to the position shown in dotted lines in Fig. 2 before they are shut again, the centre door is then freed and can be opened subsequently. A similar arrangement can be made with two doors only, in which case one of the members 18, 19 may be dispensed with.

Patent GB-837783-A (GB)
Title: Method and apparatus for feeding a solids slurry to a reaction system
IPC: B01J8/20
Filed: 1957-08-16
Abstract: <PICT:0837783/III/1> In a process for forming a slurry of solids e.g. a suspension of solid catalysts in a solvent and used for polymerizing olefines, the solids are dispersed in a water-free zone through which a liquid solvent, in measured quantity, is flowing, and the resulting slurry passes around a closed cycle, from which a part is withdrawn into a reactor.  The operation is maintained free of moisture by an inert gas e.g. nitrogen or flue gas, or by filling the system with the solvent liquid.  A suitable apparatus comprises an accumulator zone 4 fed with a solid catalyst e.g. chromium oxide supported on alumina or other inert solid, to form a bed 5; cyclo-hexane is injected through a pipe 10, and passes through an eductor 16 of venturi type drawing in catalyst through a star valve 8.  The turbulence in the eductor forms a homogeneous slurry which passes through a second eductor 20 into the closed loop 22 and is cycled by a pump 24.  A part of the suspension is withdrawn through a pipe 28 and pump 30 to a polymerization reactor.  The solvent inlet 10 includes a pressure differential element 9 which through a transmitter 11 sensitive to liquid flow variation actuates a control 12 for the motor 13 operating the star valve 8.  The speed of the motor remains constant while liquid flow is constant.  The closed loop 22, includes a pressure vessel 26 containing the circulating liquid slurry, above the level of which is gas under pressure, e.g. nitrogen or gaseous hydrocarbon.  As slurry is withdrawn through the outlet 28, level of the liquid in vessel 26 changes, and the resulting variation in gas pressure is transmitted by a pneumatic signal control 27 to a valve 29 which may increase or decrease solvent flow, whereby an increase in solvent flow speeds up motor 13, and increases the intake of solids from the bed 5.  Other powdered solids which may be formed into slurries include pumice, sand, coal, shale, lignite, or metal oxides.  Specifications 790,195 and 804,641 are referred to.
