Abstract: 1,240,105. Soaps. UNILEVER Ltd. 27 Sept., 1968 [29 Sept., 1967], No. 44599/67. Heading C5D. A soap is derived from fatty acids comprising tallow fatty acids and synthetic fatty acids, of which from 5 to 30 per cent by weight of the total fatty acids are C 11 -C 15  branched-chain synthetic fatty acids (other than solely alphamethyl tetradecanoic acid). Preferably at least 10% of the fatty acids are branched chain, a major proportion of the fatty acids are tallow fatty acids and the synthetic acids contain at least 40% of branched-chain fatty acids. The synthetic fatty acids may be prepared by the oxidation of fatty alcohols produced by the catalytic reaction of olefins with carbon monoxide and hydrogen or the acids may be obtained by catalytically reacting olefins with carbon monoxide and water. In one embodiment of the invention, the synthetic fatty acids are substantially wholly branched-chain acids. The soap may be in tablet, powder or liquid form and may contain conventional additives (e.g. titanium dioxide and preservatives).

Title: A Method of Manufacturing Plastics/Articles by Pressure and/or Vacuum forming
IPC: B29B9/00
Filed: 1966-10-14
Abstract: 1,163,547. Sheet forming. SOBREFINA S.A. 14 Oct., 1966 [9 Nov., 1965], No. 46042/66. Heading B5A. [Also in Division B8] Articles of non-uniform thickness are made by differentially heating a series of areas in a thermoplastic web, indexing each area in turn to a forming station, and finally plunger assisted pressure forming each region into the required article. In the described embodiment, for making bottle tops, a continuous web PW is intermittently indexed to a forming station through a heater comprising a series of circular electrically heated plates against which the sheet is pressed during its dwell periods. The plates are formed with a circular groove in their surfaces, the width of the groove successively decreasing until in the last plates the groove is absent. In this way the accumulative heating is such that each circular region presented to the forming station has central and outer heated highly plasticized areas (A2) and (A4 and A5) respectively, which merge into a cooler less plasticized intermediate area (A3). Each region A is peripherally shaped and clamped at the forming station by a tool B and a forming die F and then blow and vacuum formed into the die assisted by a plunger S. The cooler area A3 is compression moulded between the upper end S.U. of the plunger and the part F3 of the die, to form a thick rim adapted to receive a sealing cap, whilst the region A4 is applied to the part F4 of the die to form a neck and the region A2 is stamped out by punch M to form a central opening. Alternatively the plasticizing may be effected by heating all of the web and differentially cooling the regions A whilst completely cooling the intermediate regions.
