Title: Reinforced containers
IPC: B29C48/09
Filed: 1972-11-29
Abstract: 1456198 Moulding plastics containers IMPERIAL CHEMICAL INDUSTRIES Ltd 26 Nov 1973 [29 Nov 1972] 55088/72 Heading B5A [Also in Divisions B8D and B8P] A container of plastics material, which is blow moulded or vacuum formed from an extruded tubular parison, comprises an unfoamed layer and a simultaneously extruded foamed layer which is absent from the region in which the container wall is welded together by clamping of the parison prior to the blow moulding or vacuum forming. The unfoamed layer may comprise a polyolefine or unsaturated nitrile polymer, and the foamed layer may be a thermosetting or thermoplastic plastics, but both layers preferably comprise polyolefines. The foamed layer is foamed before, during, or after the blow moulding or vacuum forming. The parison may be of circular section, but may be locally thickened when the container is of cubical shape. The foamed layer may be on the exterior or interior of the container, and may extend completely around the container circumference, or only part way therearound such as to leave a window unobscured by opaque foam, or may extend only along the corners or around only two sides of a cubical container. The die head from which the parison is extruded may comprise an annular extrusion outlet defined between a mandrel 1 and a surrounding die 3, Fig. 2, to which the plastics of the unfoamed and foamed layers are respectively delivered along passages 7, 6, on either side of a partition 5. The absence of the foamed layer from the clamping region of the parison is obtained by displacing the partition 5 to engage the mandrel 1, at 9, and close the passage 6, the parison so being produced having the foamed layer 26 inset within the unfoamed layer 27, Fig. 2A. By displacing the mandrel 1 away from the partition 5 when both layers are being extruded, the foam layer is proud of the unfoamed layer, Figs. 3 and 3A (not shown). The die may also be displaceable, but where the foamed layer is outermost, the intermittent extrusion is preferably effected by the partition being displaceable into engagement with the die. When extruding downwardly, the die parts may be displaceable to compensate for progressive thinning of the parison during extrusion. A passage, or spaced passages 6, may alternately extend part way around the die outlet to produce the corresponding foamed layer, or layers spaced apart around the container periphery.

Abstract: 1,254,882. Protective arrangements. COMPAGNIE DES COMPTEURS. 6 Dec., 1968 [6 Dec., 1967], No. 58205/68. Heading H2K. An asynchronous motor is provided with an arrangement for producing a signal representative of the slip of the motor by determining an impedance characteristic of the motor, the arrangement comprising means producing first and second signals related respectively to a current and a voltage of the supply to the motor and means for producing a third signal which is a function of the first and second signals and corresponds to an impedance characteristic relating to the slip of the motor. In the arrangement shown, the terminals 105, 106 and 107, 108 would be connected to current and voltage transformers (not shown) in the motor supply circuit. The current signal at terminal 105, 106 is applied through a current transformer 31 to an impedance 32, 33 representative of that of the motor when stationary. The current signal is also applied to a mutual inductance 30 having identical secondary windings 30b, 30c representative of a reference impedance. An isolating transformer 35 connected to the terminals 107, 108 has its secondary winding 35b in series with the winding 30c. The resulting voltages at points α, b are applied to a coincidence circuit formed by diodes 41, 42, 47, 48 connected to the base of a transistor 44 which conducts when the voltages are simultaneously positive. An indicating instrument 55 or a relay indicates or responds to the mean value of the collector-emitter voltage of the transistor 44. In a further arrangement, Fig. 3 (not shown), current and voltage transformers supply a rectifier comparator circuit. A relay connected to this circuit becomes operative to cause tripping of a circuit-breaker only after a time delay imposed by current-responsive relay, the delay being sufficient to avoid incorrect operation during the starting of a motor. Positive sequence current and voltage filters may be used in applications where the supply to the motor might be unbalanced.

Abstract: 1381630 Scrubbing gases NIPPON KOKAN KK 20 Dec 1972 [24 Dec 1971] 58833/72 Heading B1R Fine particles e.g. soot, are separated from hot gas without excessively reducing the gas temperature whilst keeping the gas out of contact with air, by passing the gas containing the particles in countercurrent contact with a stream of falling molten metal drops which entrain the particles, allowing the drops containing the particles to flow into a static bath' of the molten metal, and allowing the particles to float on the surface of the molten metal in the bath from which they may be collected. The molten metal from the bath is continuously recycled to be brought into countercurrent content with the hot gas, and may be heated by a burner to adjust the temperature thereof. The static bath comprises two connected limbs and an inert gas is injected above one limb to apply pressure and to raise the level of the surface of the bath in the other limb. Apparatus for carrying out the separation comprises a tower 1, means 3 for injecting a stream of molten metal drops at the head of the tower, means 14 for injecting a hot gas G containing fine particles S near the foot of the tower, a static bath chamber 2 connected to the tower by conduit 4 to receive molten metal A after it has fallen in the tower in counter current contact with the rising hot gas, an outlet 21 for hot gas at the head of the tower, and means for transferring the molten metal from chamber 2 to injection means 3. Transfer may be effected by an electromagentic pump 6 which supplies the molten metal to outer tube 9 of a pair to concentric annular tubes 5, and via connecting tube portions 10 extending through tower wall 7 to inner tube 8 located inside the tower and having nozzle openings 11 constituting part of injection means 3. The tower may contain Raschig rings 13 of refractory material to improve the contact of the hot gas with the molten metal drops. A discharge outlet 15 for fine particles and a burner 22 for heating the molten metal may be located at the top of chamber 2. A removable particle-collecting container 16 having an inlet for an inert gas e.g. nitrogen, is mounted on outlet 15 with a valve 17 placed there between such that when increase in pressure in the tower e.g. by introducing an inert gas into the tower, forcesthe level of the surface of the molten metal in chamber 2 to be raised, the accumulated particles floating on the surface are forced into container 16 and can then be removed.
