Title: A method and an equipment for the making of piles of concrete in situ
IPC: E02D5/38
Filed: 1949-05-17
Abstract: 664,854. Piles. SVENSKA ENTREPRENDL AKTIEBOLAGET. May 17, 1949. [Oct. 21, 1948] No. 13170/49. Class 68 (ii). In the casting of concrete piles in situ, a tube 10 temporarily closed at its lower end by a pile point 27 is driven into the ground and concrete is supplied to the inside of the tube 10 through a tube 12 forming part of an assembly which is housed in the tube 10 but is substantially or entirely disconnected therefrom so that the shocks of the driving are not communicated to the assembly. The assembly consists of the tube 12 and a conical lower end which is welded to a ring 13 having a groove to accommodate a rubber sealing ring 15. The ring 13 defines a lower chamber 35 into which the concrete is received, the superincumbent concrete in the tube 12 producing a pressure in the concrete which tends to lift the ring 13 and associated parts. The tube 12 supports, by welded spiders 17, a number of tubes 16 which pass into holes in the ring 13 and serve to position reinforcement rods during the casting of the pile. The rods are dropped through the tubes 16, the ends, which are suitably tapered, jamming in the tapered annular groove 30 in the pile point 27. Rubber sleeves 20 depend from tubes 18 aligned with the tubes 16 and seal against the rods to prevent the upward leakage of concrete. Arms 22 project from the upper end of the tube 12 and are slidably arranged in slits 23 in the tube 10, the assembly being supported for raising and lowering as necessary by a sleeve 24 slidable on the outside of the tube 10 and having radial arms 25 for connection to the lifting wires 26. The tube 10 is first driven into the ground by a weight 34, a wooden impact pad 32 resting on a steel plate 31 to protect the end of the tube. When driving is finished, the assembly is lowered fully and the reinforcement rods 21 are dropped in. The assembly is then lifted to the extent permitted by the slots 23, a protective cover 36 is applied and concrete is supplied to the tube 12 by an eccentrically arranged hopper tube 39. When the concrete fills the tube to the level producing the desired pressure in the chamber 35, the tube 10 is pulled up slowly by the wires 26, more concrete is supplied from the hopper 41 and the tube is again pulled up progressively. A float in the tube 12 is connected by a wire to a scale to give an indication of the conditions in the tube and pile. During the extraction of the tube 10 it may be vibrated to consolidate the concrete. In a modification, the assembly is suppotted by spring means in the tube 10 which lessen the effect of the blows on the assembly. A ring is welded to the tube 12 at a little distance below its top, springs above the ring being compressed as the assembly rises, whilst springs below the ring are compressed as the assembly falls. The springs are threaded on bolts depending from a ring which is detachably secured in the top of the tube 10, this ring being spaced from the impact pad 31 by a rubber or like cushion.

Abstract: 275,753. Marks, E. C. R., (sp¾lka Lidowiecka Handlowo-Przemyslowa Sp. z.o.o.). May 29, 1926. Hulling, husking, and decorticating; scouring; reduction processes; thrashing - machines. - Material that is to be cleaned, thrashed, ground, shelled, or disintegrated, is introduced into a stationary drum M having on its inner periphery a number of chambers K with their mouths directed towards the direction of rotation of a disc W rotating within the drum, and provided with projecting blades H. A sieve grating R is arranged at the bottom of the drum for the discharge of material after treatment. Several drums and rotating discs may be arranged along one shaft, thrashing being carried out in one drum, hulling in the next, and grinding in a third. The rotation of the disc W causes looped currents of air to circulate in the chambers K and these currents cause the particles of material to be rubbed against each other and against the sides of the chambers, thus performing the desired cleaning, thrashing, or grinding operation. The disc K is arranged at one end of the drum and its blades project laterally towards the other end.
Patent GB-1063237-A (GB)
Title: Improvements in or relating to photopolymerization of vinylidene and vinyl monomers
IPC: G03F7/029
Filed: 1965-03-31
Abstract: A monomer containing the group <FORM:1063237/C3/1> is photopolymerized in the presence of water and of a ferric salt of a benzilic acid as the sole catalyst.  Specified monomers are N,N1-methylenebisacrylamide, methylolacrylamide, N-ethanolacrylamide, calcium, acrylate, acrylic acid, acrylonitrile, (meth)acrylamide, methyl methacrylate and sodium methacrylate.  The ferric salt may be performed or formed in situ from a ferric salt, e.g. FeCl3, Fe2(SO4)3, FeNH4(SO4)2 or FePO4, and the acid, e.g. benzilic acid, diphenylene glycollic acid or a benzilic acid of general formula <FORM:1063237/C3/2> wherein R1, R2, R3 and R4 are in the meta or para positions and may be hydroxyl, alkyl or vinyl groups, examples being 3,31-dihydroxy, 4,41-dihydroxy, 4-vinyl, 4,41-divinyl, 3-methyl, 4-methyl, 4,41-dimethyl and 4-hydroxy benzilic acids.  The polymerization is carried out in aqueous solution or in coated dry layers containing retained water, using U.V. or visible light. In the latter case, an aqueous solution of monomer, catalyst and a water-soluble carrier, e.g. gelatin, glue, casein, hydroxyethyl cellulose, polyvinyl alcohol or polyvinyl pyrrolidone is applied to a backing and the coating is dried prior to exposure to light. The pH of Me reaction mixture is 6 or below.  In the examples, N,N1 - methylenebisacrylamide is photo-polymerized in an aqueous solution containing the catalyst, or alternatively the solution is coated on baryta paper or film base and dried before exposure.
