Title: Improvements in or relating to methods and apparatus for aseptically filling bottlesor packages with sterile flowable substances and sealing them
Inventor: ARBER ROWLAND SACKVILLE PRESTO
IPC: B67C7/00
Filed: 1963-01-21
Abstract: 1,014,014. Filling bottles. UDEC Ltd. Feb. 12, 1964 [Jan. 21, 1963], No. 2566/63. Heading B8T. In an apparatus for aseptically filling bottles, the bottles pass successively through a sterilizing zone, a filling zone, and a capping or sealing zone, the bottles being isolated from the atmosphere throughout their travel. An endless chain, supported by wheels of which at least one is driven by a motor and having pockets in which the bottles are carried, moves step by step through a casing 10 so causing the bottles, which have been slid into the pockets from a tilting platform 32, to pass first over jets 41 where they are heated by sprays of warm liquid and then through a bath 13 containing cleansing liquid. This bath acts as a liquid seal so that when the bottles emerge on the side of a partition 17 away from the loading platform 32 they are in the isolated atmosphere since the space between the bath bottom and the casing is also filled with water. The up-ended bottles are then further sprayed by jets 34 before they pass into a bath 15 containing sterilizing liquid. After leaving the bath they are sprayed with sterile liquid from jets 39 and 40 to remove any clinging sterilizing liquid before being transferred to a conveyer 44 which moves the bottles through the filling and capping apparatus 11 and 54. The sterile liquid is rendered sterile by being pumped through an exchanger where it is first heated to approximately 300‹ F. and then cooled to about 160‹ F., the heated liquid passing to the jets 39 and 40 and the liquid then collected beneath the jets being pumped and mixed with a supply of cooling water and sprayed from jets 41, some being used to fill a liquid seal 45 through which the capped and filled bottles pass to the atmosphere. The jets are rendered operative when the chain is stationary by means of a valve mechanism operated by pneumatic motors which themselves have valves controlled by cam mechanism driven by the motor which drives the chain. Fenders are provided on the stretches of the chain in which the bottles are upright. Steam heaters 48 and 49 may be immersed in the baths, and drip sills may be provided on the roof of the casing to direct condensation clear of the bottles. The walls of the casing may be provided with openings sealed by flexible gloves enabling an operator to carry out operations within the casing. A liquid trap may be provided in the filling and capping zones through which broken bottles may be removed. A shoot may be provided for feeding sterilized caps successively to a number of press tools mounted on a rotatable head and embodying a reciprocable plunger which is associated with means for holding the caps in position. The cleansing liquid may comprise a caustic alkali, and the sterilizing liquid a caustic alkali mixed with a sterilizing agent.

Title: Improvements in and relating to the manufacture and production of tubular bodies from solutions of cellulose or of cellulose compounds
IPC: B29C48/10
Filed: 1933-01-30
Abstract: A tubular body produced from viscose, cuprammonium cellulose, or the like, after it has left the bath in which it is formed, is led more or less in a straight line and in an upwardly inclined direction while it is subjected to the action of the treating and washing liquids, and is subjected to a regulated inflation.  The cellulosic tube K may be inflated by means of a narrow tube T which passes through the <PICT:0408774/IV/1> nozzle orifice F and lies along the cellulosic tube with its end U above the level of the coagulating bath inside the tube.  If desired, the pressure within the cellulosic tube may be automatically maintained constant by means of a device which will apply vacuum or pressure to the tube T as required.  In an example, a tube formed by extruding viscose in a slightly upwardly inclined direction into a solution of ammonium salt, is passed on to two or more slightly upwardly incline conveyers on which it is sprayed firstly with the sulphuric acid fixing liquid, and then with water or steam for washing.  The tube passes between nip rollers into after-treatment baths, for example, of sodium sulphide, bleaching solution, or dilute glycerine.  These further treatments may, however, be applied whilst the tube is still travelling in a straight line in an upwardly inclined direction.
