Title: Plastics bags manufacture
IPC: B31B50/78
Filed: 1969-08-23
Abstract: A plough or gusset opener comprising a wire 8 and a part 6 of diamond cross-section (Fig. 2) is provided to separate opposed seals e.g. 5a, 5b that may have inadvertantly become sealed together e.g. 5c during their formation e.g. when forming block-bottomed bags. As shown, a folded plastics web 1 having a pleat 2 coated with a yeat-seal inhibitor on its outer surface e.g. printing ink passes to a first heat-sealing station where double V-shaped seals 5, e.g. an example of such a seal being 5a, 5d, are formed to extend partly across the pleat 2 to leave a small separation adjacent the pleat fold 9 wherein the wire 8 may lie. As the web 1 moves intermittently towards a second station providing transverse seals 13, the part 6 progressively separates the opposed arms e.g. 5a, 5b of the V-shaped seals, e.g. 5a, 5d. The wire 8 which is anchored to a support 10, passes through tubing (7, Fig. 2) brazed into a groove along the inner edge of the part 6 to be anchored to a support 11 via a tension adjustor 12. The web 1 may comprise side-gussetted, lay-flat tubing which may be cut longitudinally to form two rows of bag or transversely midway between the transverse seals 13 to form half-sized bags. The bags may be only partly severed from each other. The web may comprise films of polythene, polypropylene copolymers of ethylene or propylene with other olefines or unsaturated monomers, polyethylene terephthalate or vinylidene chloride copolymers. The film may bear a heat-seal coating on its inner surface and be used for packaging cut loaves.

Title: Spout connector apparatus
IPC: F16L5/00
Filed: 1970-01-31
Abstract: An apparatus for mounting a spout structure through an opening in a plumbing fixture Z comprises a spout pipe SP, a nut SN and a spout body SB. The spout nut SN, as shown provided with four integral arms A1-A4 each having a corresponding hinge F1-F4, is fitted over the spout pipe SP provided with grooves G1 and G2, groove G1 being fitted with an O-ring O. Alternatively, the arms A1-A4 &c. may be separable from or separate from the nut SN. The arms A1-A4 are positioned adjacent to the outer periphery of the pipe SP and the fingers F1-F4 engage the groove G2, thus preventing longitudinal movement of the pipe SP in the nut SN. The body SB is inserted through an opening in the fixture Z, the pipe SP inserted into the body SB, and the nut SN screwed on to the body SB at NP1. The 0-ring O provides a fluid seal between the spout SP and the body SB and the engagement of the fingers F1-F4 in the groove G2 enables the spout SP to be rotated but prevents longitudinal movement with respect to the body SB. A pipe PP is then inserted into the body SB and held in position by a nut BN screwed on to screwthreads NP2 on the body SB, a fluid seal between the pipe PP and the body SB being provided by a flexible washer W2 and a metal washer W3. A further washer W1 may be provided between the body SB and the fixture Z.

Title: Process for the production of polyurethane elastomers
IPC: B29C48/95
Filed: 1974-01-18
Abstract: Polyurethane elastomers made from diisocyanates, polyhydroxyl compounds (molecular weight 800-3500), glycols (molecular weight up to 300) and optionally triols (molecular weight up to 500) are produced in screw machines in the presence of lubricants. Self-cleaning, twin-screw machines with corotating screw shafts are used. In one screw zone therein, in which the kneading elements mix vigorously (kneading frequency up to 15 Hz), the critical reaction phase, in which the reaction mixture is highly tacky and has a viscosity of between 20 and 70 Pa.s, is passed through at a velocity gradient in the radial play between the comb and the housing wall of greater than 2000 s<-1>. The consequence of this is a homogeneous knot-free end product. The process enables the thermoplastic end product to be extruded directly with shaping.

To this end, a time lag contact controlled by a relay of said control circuit is inserted in the coupling of one of the three conductors and the circuit of the second part includes a memory relay which is energized by means of the two other conductors and which is no longer energized when the third phase is applied to the second part.
Patent ES-439386-A1 (ES)
Title: Static mixing device
IPC: B01F5/00
Filed: 1974-02-20
Abstract: The mixing device is constructed with a coarse mixing zone and fine mixing zone. The two zones are each generally constructed with corrugated plates or the like which are layered together to define a plurality of inclined criss-crossing flow ducts. The ducts in each layer are at least partially open to each other to allow cross-mixing. However, the upstream, or coarse, mixing zone is provided with a plate-like intermediate element, or the like, between each pair of adjacent corrugated plates to close off the adjacent flow ducts in the middle zones of the respective layers while leaving the edge zones open at least partially. This latter construction is to avoid a concentration gradient over the mixing zone and to provide a uniform distribution of the flowing media at the exit end of the zone.

Title: Method of and apparatus for measuring specific gravity or osmorality of liquid
IPC: G01N13/04
Filed: 1977-01-05
Abstract: Test materials for determining the density or osmolarity of a liq. sample comprises dye-filled microcapsules whose walls consist of an osmotically rupturable semipermeable polymer membrane. The dye-filled microcapsules are pref. polyamide capsules produced by interfacial polycondensation of a polyamine with a polyfunctional acyl halide in a soln. contg. the dye (esp Evans blue.) The density of the encapsulated soln. should be greater than that of the liq. to be tested. The materials can be used, e.g., in brewing, urine analysis and water purification. The microcapsules release the dye when immersed in the test liq., and the extent to which the dye is release is a function of the osmolarity of the liq. The results can be read off simply by comparison with a colour chart or by photometry.
