IPC: B67B5/00
Filed: 1957-02-28
Abstract: 834,463. Capsuling bottles &c. CLAYTON Ltd., G. S. May 27, 1958 [Feb. 28, 1957], No. 6726/57. Class 125(2). Relates to apparatus for applying capsules to containers such as bottles fed intermittently from a conveyer by a star wheel A into position beneath a capsuling head B which contains a resilient membrane 26 deformed to apply the capsule by liquid pressure supplied through pipe 23 and bore 25 by a piston 17 forced down by a cam 38 carried by the shaft 32 which is vertically reciprocated and also carries the head B. According to the invention, a lever 10 pivoted on axis 12 is spring-loaded into the position occupied by a bottle beneath head B, a cam 13 pressing open relief valve 16 to allow liquid from piston 17 to pass into reservoir 21 through pipe 20 instead of into the head when no bottle is present. If a bottle is present, it swings lever 10 aside to remove cam 13 from its cooperating roller 14 and valve 16 is closed by spring 16<SP>1</SP>. The maximum pressure during capsuling is determined by the adjustment of the spring pressure on a relief valve 27. To suit containers of different shape or diameter, the star wheel can be replaced or fitted with a suitably profiled plate ; the head and cam 38 can be raised relative to shaft 32 to suit different heights of containers. The head may be invertable on its bracket 36 to allow removal of the membrane without draining liquid from the liquid conduits. The highest point of the conduits may have a bleed screw for purging air. Specification 764,029 is referred to.

Abstract: 307,829. I. G. Farbenindustrie Akt.- Ges. March 14, 1928, [Convention date]. Cellulose xanthates, processes for making filaments from.-Artificial fibres, such as artificial silk or wool or staple fibre, of 3-1 denier or less and of high tenacity are obtained by spinning non-matured viscose made from non-matured alkali cellulose into a bath consisting of or containing as its main constituent one or more acid esters formed from a polybasic inorganic acid and a mono- or poly-hydric aliphatic or aromatic alcohol. Suitable esters are methyl, ethyl, and propyl sulphuric acid, methyl, dimethyl, ethyl, diethyl, and propyl phosphoric acid, and benzyl sulphuric and phosphoric acid; acid esters derived from polybasic mineral acids and polyhydric or substituted alcohols such as glycol, glycerine, trimethylene glycol, and glycollic acid are also suitable. The esters are preferably used in the crude state as obtained by mixing equivalent amounts of the alcohol with the mineral acid or its anhydride and controlling the temperature so that a maximum formation of ester occurs. The action of the bath may be controlled by using an excess of alcohol or of acid, and the bath may contain also additions intended to affect the lustre or softness of the product, such as those described in Specification 277,716. Additions may be made also to the viscose, e.g. phenol wood resin and its salts; sulphonic acids (or their salts) of condensation products of phenols or phenolsulphonic acids with aldehydes or ketones; sulphonic acids (or their salts) of mineral oils, aliphatic tars or tar-oils or their condensation products with formaldehyde etc.; or sulphonated machine oil. The tenacity of the thread can be increased by stretching it on its way to the bobbin, for instance as described in Specification 287,553, or by conducting it through a second bath, which may serve, at the same time for washing the thread. The thread may be washed also on the bobbin. An example is given. Specifications 135,205, 181,330, and 274,521 also are referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to Specification 281,352. This reference does not appear in the Specification as accepted.
