Filed: 1972-07-25
Abstract: 1436107 Injection moulding hollow articles CHLORIDE LORIVAL Ltd 23 July 1973 [25 July 1972] 34802/72 Heading B5A The invention relates to an injection mould for making hollow thermoplastic articles comprising a die 12 into which a punch 15 projects, means for locating the punch and die in relation to one another including male and female locating members and means for moving one locating member relatively to the other during the moulding operation. According to the invention, one of the locating members is formed as an injection nozzle 26 and the movable locating member 20 is retained during the major part of the injection operation with the locating surfaces spaced by a narrow clearance 30 (Fig. 3) substantially less than the wall thickness of the article, and during the final part of the injection operation the locating member is retracted so that the clearance is comparable with the wall thickness. The clearance 30 may be about fifteen thousandths of an inch. The article may be a part of a ball pen but, as shown, is an electric battery container. The punch 15 comprises six separate slabs 16 with narrow spaces 17 therebetween forming the intercell partitions. In Figs. 3, 4 the female locating surface 21 is carried by the core slab 16 and is retractable, and the male locating surface is carried by the die 12 and forms the injection nozzle 26. If desired, the male locating surface may be formed on the core slab, and may be retractable and the female locating surface may form the injection nozzle (Fig. 6, not shown) or any combination of these arrangements may be used. The movable locating member 20 may also act as an ejector. The mould opening and article ejecting arrangements are as in Specification 1,436,108.

Title: Data stores
IPC: G03H1/02
Filed: 1969-07-10
Abstract: 1,223,203. Magneto-optical stores. INTERNATIONAL BUSINESS MACHINES CORP. 10 July, 1969 [15 July, 1968], No. 34810/69. Heading H3B. [Also in Division H1] In an optically accessible data store, data is recorded by forming a hologram of the data on a film 2 of europium chalcogenide to modify the magnetization of the film. The hologram is formed by dividing a beam from pulsed laser 6 into two parallel portions 16, passing one portion through an object 20 representing the data, and recombining the portions at the film as in Fig. 1. The object 20 may be a pattern of holes or slits representing binary information. The film 2 is supported on a non-magnetic substrate 4 such as quartz, and is held at 20‹ K. where its magnetization curve is substantially rectangular. A biasing field Hb is applied to the film, the field being less than that required to switch the magnetization of the film except in those areas heated by the laser energy. A thermomagnetically recorded pattern is thus stored in the film, corresponding to the incident energy intensity. A Q switched ruby laser is stated to be suitable since it can provide a pulse which is much shorter than the thermal relaxation time of the film, and because the film absorbs energy efficiently at the output frequency of such a laser. The stored data may be read from the film using the longitudinal Kerr or Faraday effects, Fig. 2 (not shown).

Title: Improvements in and relating to the rectification of alcohol
IPC: B01D3/40
Filed: 1929-11-18
Abstract: <PICT:0347122/III/1> Weak solutions of alcohol are subjected to a preliminary refining in an auxiliary column containing only six or seven plates whereby a small amount of the feed liquid, not exceeding 3 per cent, is vaporized; the water-insoluble or slightly soluble impurities are removed by this treatment leaving only the alcohol and water-soluble impurities which are removed and the alcohol p concentrated in known manner.  In the form shown, wort containing say 5 per cent of alcohol is fed to the auxiliary column A from a vessel M by a pipe 2, the wort passing through a preheater 1. Steam, supplied by a pipe 3, may be used to raise the temperature sufficiently to cause a stream of vapour to pass from the head of the column A through a pipe 13 to a small column B in the outlet pipe of which a cock 4 is provided whereby the amount of vapour passing is confined within the desired limits.  Hot water at about 95 DEG  C., amounting to about 5 per cent of the wort treated, is supplied to the top of the column B by a pipe 6 to prevent alcohol from passing over. The vapours from the column B, containing only the water-insoluble impurities, pass to a condenser C and are drawn off at 5.  The wort, containing only alcohol and water-soluble impurities, passes by a pipe 8 to a column D where it is treated in known manner, pure alcohol being drawn off by a pipe 11, a final purification being effected, if desired, by a small column G.  Water-soluble impurities are drawn off at 10.  In a simplified form, the column B is dispensed with.  The same treatment may be applied to the purification of methyl alcohol.
