Title: Bubble tray for vapour liquid contacting columns - employing radially segmented risers and downcomers
IPC: B01D3/18
Filed: 1974-04-16
Abstract: A bubble tray for columns of circular cross-section is split radially into segments so that gas inlet and liquid outlet occupy alternate segments. Liquid from the downcomers splits to feed the two adjacent liquid separator segments after passing through areas of intense vapour-liquid contact. The separators themselves have raised walls to increase the mean residence time on the plate and give rise to liquid flow radially outwards to the periphery of the column. For vapour-liquid contacting applications in the oil and chemical industries in which vapour and liquid pass in counter-current flow.

Title: Double acting injection moulding press for thermosetting materials - with rapid downstroke and slow upstroke reduces moulding cycle
Inventor: BRIZAY ROLAND
IPC: B29C45/67
Filed: 1975-07-21
Abstract: A moulding press for a flash mould carries the mould halves on an upper platen and on the press table. Mechanisms are provided for causing the rapid descent of the upper platen, its locking in a predetermined position close to the table, and the slow rise of the press table to close the mould, and to reverse the movements. A process for using the press is claimed in which the upper platen is rapidly lowered, halted and injection of plastics material commenced while the mould is closed by raising the press table. After curing the moulding the press table is lowered to allow ejection and the upper platen finally raised to its initial position. A flash groove allows some moulding material to flow from the mould but is sealed pref. by hardened material from a prefious cycle. A quicker moulding cycle is possible, with greater moulding precision.
