Title: Improvements in and relating to Reinforced Concrete Elements
Inventor: IPSEN JANNIK
IPC: B28B23/04
Filed: 1968-04-04
Abstract: 1,177,447. Moulding reinforced concrete elements. DANSK SPAENDBETON A/S. 4 April, 1968, No. 16177/68. Heading B5A. Plate shaped concrete elements, e.g. ceiling elements comprising prestressed reinforcement and longitudinal parallel bores are made in an elongated mould divided by element end members, the prestressed reinforcement being common to all the mouldings. As shown, the elements are moulded in apparatus comprising a rigid base 1, from which the mould base 4 (which may be up to 100 m. long) is separated by spacers 3. At each end of the mould, a trench 2 houses the reinforcement tensioning apparatus 7. Side moulds 5 are fixed along the length of the mould base and the individual elements are divided by end members 6 comprising a bottom part 13 and a top part 14, the bottom part having slots 16 into which the reinforcement is placed and a recess 15 which co-operates with recess 19 on the top part to accomodate the core. To mould a building element, the bottom parts 13 of the end members are spaced along the mould and attached to the side members. Reinforcing members are laid along the length of the mould in the slots 16 and are tensioned by apparatus 7. Concrete is then poured into all the mould sections to cover the reinforcing rods. Cores of greater length than one element are then located in the bottom end sections 13 of at least the first element and, the top sections 14 required to hold these cores in position are fitted and concrete is cast into the moulds so formed. When the concrete has hardened sufficiently for it to be self supporting the cores and top sections 14 are advanced to the next section of the casting mould and the process is repeated, thereby reducing the number of cores and top sections needed. The elements are removed from the mould by removal of the mould sides 5. The elements may be made with a chamfered edge by making the top section 14 of a trapezoidal cross-section.

Title: Improvements in and relating to the production of film and tubing of organic thermoplastic material
IPC: B29C48/03
Filed: 1959-05-14
Abstract: In the inflation method for the continuous production of biaxially stretched tubular films of organic thermoplastic material having an orientation of at least 400% and a tensile modulus in excess of 100,000 p.s.i. the walls of the inflated tubing are caused to converge gradually in the extrusion direction and thereafter the walls are brought in parallel and spaced relationship with one another.  In the zone in which the walls are parallel to one another and spaced a short distance apart (e.g. 1/4 to 1/2 inch), the film is heated to 5 DEG -15 DEG C. above the second order transition temperature of the film material for 5 to 120 seconds and the film is then completely collapsed and simultaneously subjected to further longitudinal stretching while maintaining its temperature within the above range.  In the example, a styrene homopolymer of molecular weight 70,000 and a second order transition temperature of 82 DEG C. is extruded at 160 DEG C. in the form of 1 1/2 inches diameter continuous tubing, which is inflated to a diameter of 9 inches and fed through a collapsing frame 60 inches long and a parallel section frame 8 inches long to two rollers maintained at 95 DEG C. which withdraw the tubular film from the extruder at a rate greater than the rate of extrusion.  The collapsing frame comprises two conveying rows of rotatable rollers set at an included angel of 15 degrees and the p  parallel section frame comprises two parallel rows of rotatable rollers spaced 3/8 inch apart.  The parallel section is maintained at 95 DEG C. and from this section the tubular film is passed over the two driven rollers in S fashion, the second roller being driven at a somewhat higher peripheral speed than the first roller so that the film is completely flattened.  It is then slit and passed in S fashion over two rollers maintained at 20 DEG C. and driven at a somewhat higher peripheral speed than the first two rollers.  Films produced according to the invention are free from wrinkles and creases.  Specification 922,083 is referred to.
