Title: Method and apparatus for blow molding
IPC: B29C49/32
Filed: 1965-11-18
Abstract: 1,096,548. Blow-moulding; reciprocating extruder. SHIN-ETSU CHEMICAL INDUSTRY CO. Ltd., and S. TERAOKA. Nov. 18, 1965 [Nov. 20, 1964], No. 49075/65. Heading B5A. In an extrusion-blow moulding process, a parison preferably tubular [a, Fig. 1) is extruded from a downwardly-directed extruder head (6) mounted above at least two moulds (9, 10), the extrusion die being vertically reciprocable relative to the moulds, and extruding on the upward stroke. During the subsequent downward stroke, the parison is fed to one of the moulds (9 in Fig. 2, not shown) and it is then severed from the die (during which the upper end of the parison and the lower end of the next parison may be sealed), and blown while the next parison is extruded on a further upward stroke of the head (6). The moulds (9, 10) are reciprocated horizontally relative to the head (6) to align each in turn therewith while the other is cooled and opened for-removal of the article. Apparatus shown in Fig. 1 comprises a plasticizing and feed device (4), a downwardly-directed extrusion head (6) connected thereto, means for supporting the moulds e.g. movable platens 14, 141 mounted on guide rails and a fixed platen, 15, mounted between the movable platens, all of which are mounted on a movable carriage, 11, and operated by hydraulic piston (16) so as to align each mould alternately with the extrusion head (6), means for opening and closing the mould halves (9, 91, 10, 10<1>), e.g. hydraulic pistons (13, 131), means for moving the extrusion head vertically relative to the moulds, e.g. hydraulic pistons (7, 7<1>), and means to inject fluid into the parison to expand it, which may pass through the centre of the extrusion head.

Title: Polymer receptivity to dyestuffs
IPC: C08K5/372
Filed: 1966-11-09
Abstract: Extrudible compositions comprise a crystalline olefin or aryl-substituted olefin polymer and a metal complex of a Mannich base of a phenol sulphide of formula <FORM:1102215/C3/1> where R is alkyl and R1 is alkyl or hydrogen, in amount sufficient to improve the receptivity of the polymers to disperse and chelating dyes. Specified polymers are polyethylene, polypropylene, polybutene - 1, poly - 4 - methyl-pentene-1 and polystyrene.

Abstract: 1,170,795. Selective change-over pipe connections. J.P. BEMBERG A.G. 14 Nov., 1966 [24 Dec., 1965], No. 50981/66. Heading F2G. A changeover connection device for connecting a selected one of at least two parallel supply pipes having flanged ends 3 and 4 to a consumption pipe (not shown) includes an intermediate rotatable pipe 11 connected to the consumption pipe at one end and provided with an expansible sealing ring 12 at the other end which is automatically releasable from a portion of an apertured plate 7 adjacent one flanged end before or during commencement of the rotatable pipe and automatically engageable with another portion of the plate adjacent the other flange on alignment therewith, the pressure in the sealing ring being controlled by pressure transmitted from the interior of the intermediate pipe. The sealing ring is housed in rotatable plate 8 which is fixed to the intermediate pipe and which is rotated by a motor 20 engaging a toothed ring 9 of the plate. The sealing ring interior is connected by pipes 13 and 18 through control and pressure piston/ cylinder assemblies 14 and 15 to the interior of the intermediate member. On shutting a valve in the supply pipe 1, pressure is decreased in the intermediate pipe and the pistons 16 and 17 of the assemblies move down to release pressure in the ring. The motor 20 is started to rotate the intermediate member into alignment with the second supply pipe 2. A valve leading to pipe 2 is then opened, the subsequent rise in water pressure in the pipe moving pistons 16 and 17 to expand the sealing ring into sealing engagement with the plate 7. The piston 14 may act on a shut-off control in the motor supply line to prevent the motor being started when the valve of the connected supply pipe is open.
