Title: Process for the polymerisation of olefins
IPC: C08F10/00
Filed: 1956-08-22
Abstract: Olefines are polymerised using a Ziegler type catalyst in an organic liquid diluent and characterized in that agitation is effected and reaction heat is abstracted by the continuous circulation of excess olefine whereby liquid diluent is evaporated at a temperature below its boiling point.  The amount of cooling may be adjusted by controlling the amount of diluent vapour in the recycled olefine and/or by the use of an inert gas in the olefine stream.  Condensed diluent is also recycled.  Olefines specified are ethylene, propylene and butylene and in examples the catalyst components used are Ti Cl4 and Al Et3 or Et2 Al Cl.  The reactions are carried out at 70 DEG  C and 40 DEG  C in cyclohexane as organic liquid diluent.  A suitable apparatus is described.

Abstract: 918,468. Laminates. STOREY BROS. & CO. Ltd. July 18,1961 [July 22, 1960], No.25702/60 Class 140. A tile comprises a stiffener sheet of a relatively rigid material having each of its faces covered by a plastic sheet, the outer face of one of the plastic sheets having a coating of a pressuresensitive adhesive enabling the tile to be caused to adhere to a surface to be curved. The stiffener sheet may be made of foamed polystyrene or cardboard. The plastic sheets may consist of polyvinyl chloride. A layer of soft padding material, such as a plastic foam, e.g. foamed polyurethane, may be incorporated between the plastic sheet forming the front face of the tile and the stiffener sheet. The adhesive on the faces of the plastic sheets may be protected by removable cover sheets of paper or other material. A tile may be made by first preparing the component parts, i.e. a stiffener sheet of foamed polystyrene, a larger facing sheet of polyvinyl chloride coated with pressuresensitive adhesive on one side, a sheet of polyvinyl chloride coated with pressure-sensitive adhesive on both sides, and a sheet of foamed polyurethane. The sheet of foamed polyurethane is placed on the adhesive side of the facing polyvinyl chloride sheet and the two sheets are bonded by gentle pressure. The stiffener sheet is then placed on the foamed polyurethane and marginal portions of the facing sheet are bent over the edges of the stiffener sheet and secured to the other face of the latter. The other polyvinyl chloride sheet is then placed over the stiffener sheet and the marginal portions of the first polyvinyl chloride sheet and secured by gentle pressure.

Title: Improvements in processes for the manufacture of "beer"
IPC: C12H6/04
Filed: 1958-08-20
Abstract: Beer, including ale, lager beer and stout, of improved keeping qualities and flavour is attained by chilling either wort from which beer is to be brewed, or the beer obtained, or both the wort and the beer, to a fluid slush ice condition, unchilling the wort or beer, and separating, e.g. by filtering or centrifuging, precipitated material from the unchilled wort or beer; an adsorbent material such as bentonite or asbestos may be added to the wort or beer to be chilled in order to avoid re-solution of precipitated material on unchilling.  The wort or beer, which may be held chilled for a period of from one to seventy-two hours, is preferably unchilled in heat-exchange with incoming wort or beer. Chilling may be accomplished by mixing suitable proportions of frozen wort or beer with wort or beer at a temperature just above the freezing point. According to an example, wort or beer, cooled to 34 DEG  F., was passed through one side of a heat-exchanger fitted with a rotating blade which removed the wort or beer as it froze on the surface of the heat-exchanger; the other side contained boiling ammonia or another suitable refrigerant.  The speed of chilling was varied to obtain chilled wort or beer in a fluid, slush ice condition.  After a suitable period, the wort or beer was unchilled and was passed through a diatomaceous earth filter.
