Title: Packages
IPC: B65D6/00
Filed: 1971-05-14
Abstract: 1367637 Packages formed of moulded thermoplastic compositions IMPERIAL CHEMICAL INDUSTRIES Ltd 10 Nov 1971 [10 Nov 1970 14 May 1971] 53345/70 and 31418/71 Heading B8C A sealed package, such as a drum, or bottle, comprising contents partially, or totally, enclosed by a moulded container is formed from a thermoplastic composition which comprises a homogeneous copolymer of acrylonitrile and at least one aromatic olefine, the molar concentration of units of acrylonitrile being within the range of 86% to 93%. The thermoplastic composition may contain a compatible graft copolymer having a diene rubber substrate, the concentration of which is such that its rubber content is not more than 50% by weight of the thermoplastic composition. In order to prevent enrichment at the end of the polymerizing reaction precautions must be taken to feed the monomers, or at least the aromatic olefine, into the reaction medium throughout the course of polymerization. The acrylonitrile-aromatic olefine homogeneous copolymer allows injection, or blow, moulding of a container while imparting to it optimum impact resistance and impermeability of the container to gases. A suitable graft polymer comprises a superstrate having at least one aromatic olefine homogeneously copolymerized at a ratio of between 1 : 2 and 1 : 9 with acrylonitrile, the graft having a suitable refractive index if the thermoplastic composition of the container is transparent. The softening point of the copolymer and/or superstrate may be increased by adding a copolymerizable cyclic compound such as maleimide, and the thermoplastic composition may have additives such as dyestuffs, pigments, fillers, plasticizers, stabilizers, processing aids, and fungicides &c. The container may be comoulded with any other thermoplastic having a suitable melt viscosity such as rigid P.V.C. or polyolefin. The container may also be formed from a paper coated with the thermoplastic composition. The contents of the package may contain beverages, wines, acids, refrigerants and aerosol propellants, &c.

Title: Means and method for controlling the strength of acid in an alkylation unit
IPC: C07C2/62
Filed: 1972-07-06
Abstract: 1362894 Automatic control TEXACO DEVELOPMENT CORP 6 July 1972 [5 Aug 1971] 31575/72 Heading G3R [Also in Division C5] In alkylation apparatus, where an olefin is reacted with an isoparaffin in the presence of an acid catalyst, to form an acid-hydrocarbon mixture that is then separated, a portion of the acid being recycled and the remainder being discharged and replaced by fresh acid, the strength of the acid is regulated according to the actual acid strength, and the olefin input composition and flow-rate. As shown, butylene or propylene is reacted with isobutance in mixer 4, using a sulphuric acid catalyst, the resultant mix being separated in settler 12 into hydrocarbons, discharged through line 14, and acid, recycled by pump 20, a portion of the acid being discharged via line 21, fresh acid entering through line 17. The acid discharge flow-rate, as detected by sensor 33, is maintained at a required value from set point means 28. This value is varied according to an average acid strength signal, calculated using analogue or digital techniques from the time of titration of an acid sample with caustic as determined by programmer 27, and an anticipated required value which is calculated from the olefin input flow-rate from sensor 40, and input composition from chromatograph 38. The discharge flow-rate is thus adjusted for each acid sample taken, using the programmer 27 to start and stop the acid analysis, and to recycle the apparatus. If for example the acid strength is too low, acid discharge is increased, with subsequent increase of inflow of fresh acid to maintain the liquid level in settler 12 at a pre-set value, and thus regulate the acid strength. Circuits 27, 28, 35 and 36 are described with reference to Figs. 2-6 (not shown).
