Title: Improvements in or relating to the storage of ozone
IPC: F17C11/00
Filed: 1963-02-19
Abstract: <PICT:0970390/C1/1> A method of storing ozone comprises dissolving the ozone at a temperature below - 95 DEG  C. in a fluorinated hydrocarbon which is liquid at that temperature, for example a fluorochloro-methane, introducing the resulting solution at said temperature into a pressure-resistant storage container, closing said storage container, and allowing the temperature of the solution to rise to room temperature, characterized in that the storage container comprises a glass vessel, into which the solution is introduced, disposed within a pressure-resistant metal vessel, and in that the difference in pressures exerted on the inner and outer surfaces of the glass vessel during the rise in temperature and thereafter at least until said ozone is required for use is kept at a value below that necessary to fracture the glass vessel, for example by providing the glass vessel with a valve, preferably also of glass, so that gas may pass from within the vessel into a space between the metal and glass vessel.  The inner surface of the metal container may be coated with a synthetic plastics material which is substantially inert to ozone, for example polytetrafluoro-ethylene. In a modification, the glass vessel is sealed after filling, and thereafter a gas, for example oxygen, helium, argon, nitrogen, or a fluorinated hydrocarbon is introduced into the space between the glass and metal at a rate predetermined to maintain the pressure differential. The Figure shows a suitable container for the exercise of the invention, in which a glass vessel 1 fitted with a ground glass ball valve 3 is disposed in a metal container 5.  To obtain the ozone for use, the valve 8 is opened, whereupon the pressure differential will increase and thus the glass vessel will burst. Specification 952,230 also is referred to.

Title: Improvements in or relating to the production of flattened tubular film of organic thermoplastic material
Inventor: GLYDE BRIAN STANLEY
IPC: B29C48/90
Filed: 1959-02-27
Abstract: <PICT:0872115/IV (a)/1> <PICT:0872115/IV (a)/2> <PICT:0872115/IV (a)/3> An apparatus for producing flattened tubular film of organic thermoplastic material comprises an extruder 1 (Fig. 1), an extrusion nozzle 2 arranged to effect the continuous downward extrusion of a tube of the molten material, and a tube 3 for the inflation of the tube with air so as to maintain therein a volume of air such that the degree of inflation of the tube, in combination with the rate of withdrawal of the tube, reduces the thickness of the tube to a predetermined value and converts it into a tubular film 4 of predetermined diameter and gauge.  The tube is continuously withdrawn downwardly by a pair of pinch rolls 5, 6 which also flatten the tube, which is wound on to a reel 7. En route to the rolls, the tube is cooled and set by directing on to the unenclosed tube in the vicinity of its initial inflation a continuous curtain 8 of a cooling liquid such as water.  The curtain impinges on the tube and runs down over it towards the rolls 5, 6 to be collected in a container 9 beneath the rolls. The cooling device may comprise a hollow annular member provided around its inner face 10 (Figs. 1 and 2) with a slit-like jet orifice 11 communicating with a chamber 12 to which the cooling liquid is delivered under pressure.  The orifice 11 may be directed downwards towards the direction of movement of the tube, as shown in Fig. 3.  The annular member may be located at a level somewhat above that of the face of the extrusion die so that the annular area of impingement of the curtain of cooling liquid is located close to the point of extrusion.  The inflated tube may be pre-cooled by a stream of air from an annular jet surrounding the tube before the tube passes through the curtain of cooling liquid. The apparatus enables the distance between the die and the nip rolls to be reduced and facilitates the production of films, particularly of polyethylene, of superior gloss and clarity.

Abstract: 1,026,897. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 19, 1965 [Feb. 25, 1964], No. 7180/65. Heading G4C. In a data storage system, using magnetic cores for example, a word stored in a main store and comprising a character with one or more permanently defective bit positions has inserted therein a marker character and the addresses in an auxiliary store of characters substitutable for the said addresses, marker character and defective character. The invention is described for 8-character words having one or two adjacent defective characters. The defective character or characters in a word are preceded or followed by a marker character (which is 11111111 or 11111110 depending on whether it precedes or follows the defective character or characters) and two address characters giving the X and Y addresses respectively of the auxiliary memory word storing the replacement characters. This latter word will store four or five characters depending on whether there are one or two defective characters, the high order bit of the Y address being 0 and 1 in these two cases respectively. During accessing of a word location in main store for reading or writing, the stored word is placed in a register and checked to see if any character (other than the first and last which cannot be marker characters) has 1111111 as the top seven bits. If not, the word is perfect and can be passed to the output, or replaced by an incoming word to be written in memory. If any character is a marker character, the remaining bit position is checked to see if it is 0 or 1 to select those characters which are the address characters and use them to obtain the substitute location in the auxiliary memory. This location is used to provide the substitute characters during read-out or store them during write-in.
