Title: Aseptic filling of containers
Inventor: ANDERSON IAN MCARTHUR
IPC: B67C7/00
Filed: 1982-08-17
Abstract: A method and system for aseptic filling of containers. The flexible containers (1) are presterilized and a rupturable membrane (41) covers the inlet to the container. The filling head (20) includes a recess (46) below the outlet valve (24) and this recess is closed by the rupturable membrane (41) when the container inlet is aligned with the filling head. After alignment sterilizing fluid is introduced into the recess to sterilize the outer surface of the membrane and the internal surfaces of the recess. Following sterilization the valve membrane (22) moves towards the rupturable membrane (41) allowing the piercing tool (25) to rupture said membrane. The outlet valve (24) of the filling head is opened and the liquid is allowed to flow into the container. Subsequent to completion of the filling cycle the inlet to the container is sealed and the sealed and filled container (1) is then removed from the filling head (20).

Title: Impact testing machine
Inventor: ISHERWOOD DAVID PAUL
IPC: G01N3/30
Filed: 1983-08-10
Abstract: An impact testing machine in which a striker 6 is held by a pivotted arm 1 which lies in a horizontal plane and is accelerated to high rotary speed.

Title: Degassing of water using inert gas
Inventor: HENRIKSEN NOROLF
IPC: C02F1/20
Filed: 1983-09-09
Abstract: Water is degassed in a gas/water stripping system using a recirculating inert gas, which is regenerated and purified in the gaseous state. The water may be sea water which is to be used as injection water in underground oil reservoirs to obtain a higher degree of hydrocarbon recovery. Gas-liquid contact may be in a scrubbing tower 2, or in a gas-lift pump. Water enters via pipe 3, and degassed water exits at 12. Stripped gas, including oxygen, leaves via 6, and make-up air enters via 11, and is mixed with hydrogen fed from electrolyser 7 by pipe 8. The gas mixture is catalytically reacted in 10 to remove oxygen (the undesirable gas) to form a mixture of nitrogen (the inert stripping gas) and water, which is recirculated via pipe 5 to the stripper. <IMAGE>
