Title: Improvements in devices for moulding of concrete beams
IPC: B28B7/08
Filed: 1959-07-13
Abstract: 916,202. Casting concrete. WENNSTROM, E. July 13, 1959, No. 23935/59. Class 87(2). A mould 1, for casting concrete beams, is mounted on trunnions 5 in a frame 3 and has a detachable cover 4. When the concrete has been poured in, the mould is inverted and the cover then serves to support the moulded beam. Bridging frames 10, Fig. 3, may be fitted to enable moulded beams to be stacked. The mould walls 6a, 6b converge and a suction effect arises as the soft concrete leaves the mould which creates uneven surfaces 8a, 8b on the mould beam. When beams are placed side by side, V-shaped spaces result between the sloping sides of adjacent beams which are filled with grouting, and the bonding effect is improved by the surface unevenness. Beams may be moulded with lightening holes and may incorporate reinforcement.

Abstract: Organic fertilisers having a sewage base are produced by treating sewage with a fermentation catalyst comprising one or more of the following elements or compounds thereof: germanium, vanadium, molybdenum or cadmium.  Manganese compounds may also be present.  The sewage, which may be dried (e.g. to a 30 per cent moisture content) and sifted, may be put into heaps and sprayed with a solution of the catalyst and allowed to ferment, after which it may be sifted and put into sacks.  The catalyst e.g. a mixture comprising vanadic oxide, molybdic oxide, braunite and cadmium borotungstate, may be added in a medium which is preliminarily slightly acidified.  Nitrogenous microbic cultures e.g. azobacters, amylobacters or the bacillus radicicola, may also be introduced conjointly with the catalyst or after the addition of the catalyst.  An active organic material, e.g. slaughter-house blood, may also be added in an amount for example of 20 litres per ton of sewage treated.  A binder e.g. domestic sewage, residues of wine manufacture &c. may also be incorporated with human sewage. The fermented medium may be brought to a pH value of about 7.5 by the addition of lime.  The Specification as open to inspection under Sect. 91 comprises also the use of manganese and its compounds as a fermentation catalyst.  This subject-matter does not appear in the Specification as accepted.

Filed: 1965-06-08
Abstract: 1,099,135. Closing bags and tubular casings. J. J. FRANK. June 8, 1965 [June 8, 1964], No. 24243/65. Heading B8C. A machine for clinching a pliable fastener around an object, e.g. a twisted bag neck or a bundle of straight wires, comprises upper and lower dies, a frame mounting an upper die support, above the lower die, and having a fastener inlet passage and means for supplyng fasteners in file at the passage, the upper die being driven down to engage and separate the fastener and deliver it to the lower die face where it is pressed, by the complemental die faces, around the object, the upper die returning to its original position. The fasteners G are fed laterally from a magazine, Fig. 1 (not shown), into the cut-away portion 22 of groove 11 in a die housing D, in which groove a clinching die E reciprocates, its upward movement being limited by the engagement of a stud 14 in a slot 15 in the housing D. The housing is reciprocable in the machine frame C against the resistance of a spring-loaded friction block 6, its upward movement being restricted by a stud 9 abutting the end of a groove 10. When the upper die E is moved downward, e.g. by a fluid pressure motor, its face 21 engages a fastener which is guided down the recessed edges of the groove 11. The housing D remains stationary until a shoulder (16), Fig. 3 (not shown), on the die E engages the toe 17 of a spring-biased dog 18 when the die and housing move together, Fig. 3 (not shown), until the lower die F, on which rests the bag neck, is almost reached, when the tail of the dog 18 engages a shoulder 24. The toe 17 then releases the shoulder 16 and the die moves alone to deliver the fastener legs into the double grooves (23), Fig. 10 (not shown), in the lower die face, pressing the fastener between the die faces to form a helical seal around the bag neck. The upper end of die E then abuts a stop 27 on the housing D and they continue down to finally crimp the fastener around the neck. Simultaneously, a blade 28 co-operates with a blade on the lower die to sever the excess end portion of the neck. The upper die and housing are then returned to their original positions.

Abstract: 929,562. Aerials. G.S.V. (MARINE & COMMERCIAL) Ltd. Nov. 2, 1959 [Aug. 1, 1958], No. 24946/58. Class 40 (7). A wide-band unipole or dipole aerial is provided with an internallyarranged stub element. The stub is of shortcircuited quarter-wavelength type but a shortcircuit at a distance other than a quarter-wavelength may sometimes be preferred. An advantage of the stub is that a D.C. path to earth is provided from every part of the aerial enabling protection against lightning and improved mechanical strength to be obtained. In a dipole embodiment the upper arm 10 of the dipole contains a coaxially arranged tube 12, a quarter-wavelength stub being formed between these two units and being short-circuited at its upper end by conductive disc 13. The tube 12 extends downwardly through the lower dipole arm 11 and forms a support for the aerial. A coaxial feeder is led up through the tube 12 and is passed through an aperture 15 in the wall thereof opposite the gap between the dipole elements. At this point the inner conductor of the feeder is coupled to the upper dipole element as at 17 and thus to the outer conductor of the stub. The outer of the feeder is connected to the tube 12 and to the dipole element 11 which may be supported from the tube 12 by conductive flange 14. A unipole embodiment, described with reference to Fig. 2 (not shown), is similar but the element 11 is not present and the flange 14 is extended to form the ground plane for the unipole.
