Patent GB-341074-A (GB)
Title: Improvements in the manufacture and production of ethers of vinyl alcohol
IPC: C07C43/16
Filed: 1929-10-07
Abstract: Ethers of vinyl alcohol which may be used as solvent or for the manufacture of artificial resins are obtained by treating ethylene or ethylidene dihalides with alcoholates or phenolates, or with mixtures of an alcohol or alcohols with alkali or alkaline-earth metal oxides or hydroxides, in the presence of organic diluents. Suitable temperatures for the reaction are 50-200 DEG  C., the higher temperatures being employed when working with phenolates.  The reaction may be carried out at atmospheric pressure, or increased pressure may be employed, for example, by working in a closed apparatus or by introducing inert gases such as methane, nitrogen, hydrogen, or mixtures thereof.  When working at atmospheric pressure it is preferable to circulate the vinyl halides formed intermediately through the reaction mixture, the resulting ether with excess of vinyl halide being removed from the reaction vessel and separated in a condenser.  The process may be effected continuously by leading the starting materials into a suitable vessel such as a tower, and continuously removing the vinyl ether and metal halide as they are formed.  Particularly suitable as diluents are solvents for the reaction components, for example, aliphatic, cycloaliphatic, or aliphatic-aromatic mono-or polyhydric alcohols or phenols.  It is preferable to employ as a diluent the alcohol corresponding to the alcoholate present. Suitable diluents acting as suspending agents are liquid aliphatic, aromatic, or hydroaromatic hydrocarbons.  Non-acid drying agents such as quickline, anhydrous sodium sulphate, copper sulphate, or potash may be present.  The reaction may be effected with mixtures of different alcohols or alcoholates, and in this case the mixture of vinyl ethers produced may be separated by fractional distillation.  Examples are given in which the preparation by the above methods of vinylethyl ether, vinylbutyl ether, and vinyl-m-cresyl ether is described.

Title: Improvements in and relating to the manufacture of capsules
Inventor: PLOURDE NEAL NEEMAN
IPC: A61J3/07
Filed: 1954-10-23
Abstract: 755,396. Moulding capsules. GUNNELL CAPSULATIONS, Inc. Oct. 23, 1954, No. 30596/54. Class 87(2) Capsules are made and filled simultaneously by feeding measured charges of encapsulating material, e.g. gelatin, and filling material, e.g. medicament, in a liquid state into a mould in concentric streams and allowing the encapsulating material to harden so that it forms a seamless shell enclosing the filling material, the feeding of the encapsulating material commencing shortly before and terminating shortly after that of the filling material to ensure that the charge of filling material is completely covered. The mould is cooled or heated according to whether a thermoplastic or thermosetting encapsulating material is used. The apparatus shown comprises a series of cylindrical moulds 10 mounted on brackets 32 which are slidable vertically in arms 28 carried by an intermittentlyrotated hollow shaft 15, each mould comprising a jacket 14 through which cooling water is circulated by means of flexible pipes 16 and 17 connected to the shaft 15. The bottom of each mould is closed by a plunger 41, 43 which is held in position by a packing ring 42 and arranged to be moved upwardly by a plunger 44 at a discharge station to eject a completed capsule 13. A cam-actuated plunger 48, located at a station intermediate the discharge and filling stations, operates to return the plunger 41 to a predetermined position, the stroke of this plunger being adjustable to,vary the capacity of the mould. The brackets 32 are urged downwardly by springs 34, and each bracket is elevated at the filling station by a plunger 36 which is operated by a camactuated lever of adjustable length (see Fig. 3, not shown). The contour of the cam is such that the bracket is then lowered at the filling rate and finally returned quickly to its original level to break the stream of gelatin. The gelatin and filling material are delivered to successive moulds through a nozzle 51 comprising concentric tubes 52, 53 connected by pipes 58 and 83 and twoway valves 61 and 81 respectively to reservoirs 57 and 78, the valves being operated in synchronism with plungers 59 and 80 whereby measured charged of gelatin and filling material are drawn into chambers 62 and 82 and delivered to the nozzzle. The plungers are operated through links and levers by cams 65 and 96 on a shaft 66, the effective lengths of the levers being adjustable to vary the strokes of the plungers and hence the quantities delivered in accordance with the size of the moulds. The plunger 80 operates a lever 91 on the filling stroke to tension a spring 93 so that at the end of the stroke it is retracted quickly, to an extent determined by engagement of a screw 94 and stop 95, to break the column of filling material. The gelatin reservoir 57 and pipe 58 are surrounded by a jacket through which a heated liquid is circulated, and the filling material reservoir 78 and pipe 83 are surrounded by a similar jacket through which a coolant is circulated.

Abstract: 388,863. Expanding pulleys. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Oxford Varnish Corporation ; Detroit, Michigan, U.S.A.) Nov. 6, 1931, No. 30846. [Class 80 (ii).] In a machine for graining furniture parts &c. a common drive for the pattern roll and the two co-operating transfer rolls is provided, which includes a progressively variable-speed driving connection for both transfer rolls, whereby the peripheral speed of either transfer roll may be synchronized with that of the pattern roll. A motor 4 drives through reduction gearing 4a a sprocket 25 which is connected by a chain 26 to a sprocket secured to the shaft 6 of the pattern roll 5. Another sprocket secured on the shaft 6 is connected by a chain 30 to a sprocket fast to a shaft which is geared to a lay-shaft 37. The layshaft 37 carries a double-cone driving- pulley having elements 38, 39 connected to a similar driven pulley having elements 42, 43 by a belt 45. Both the transfer rolls 10, 12 are driven by a sprocket-and-chain arrangement from the shaft 40. The peripheral speed of the particular transfer roller in use may be adjusted to correspond with that of the pattern roll by the adjustment of the double-cone pulleys. The pulley element 39 is mounted on a tubular extension of the pulley element 38, which extension is threaded to receive a nut or flange 61, adapted to retain the element 39 against the action of a number of interposed springs. The element 39 is slotted to slide over a key provided in the tubular extension. When it is desired to adjust the speed owing to wear &c., the flange 61 is turned to move the element 39 toward, or allow it to retreat from, the element 38, thus either forcing the belt 45 to ride at a greater distance from the axis of the shaft 57 to increase the speed of the driven shaft 40, or to allow it to ride nearer the axis and thus decrease the speed of the driven shaft 40. The flange 61 is tapped to receive a screw which is adapted to engage one of a number of recesses in the pulley element 39 on adjustment of the latter. The relative adjustment of the , pulley elements 42, 43 are the same as for the pulley elements 38, 39.
