Title: Improvements relating to bridges and bridge-like structures and structural elements
IPC: E04H12/02
Filed: 1948-09-13
Abstract: 693,423. Bridges; hangars; beams; floors. HAMILTON, A. M. Sept. 7, 1949 [Sept. 13, 1948], No. 24011/48. Classes 20(i), 20(ii) and 20(iv) Bridges or bridge-like structures such as hangers which extend across a considerable free span comprise a hollow tubular shell of rigid material filled with gas under pressure e.g. hydrogen or helium. The shell may be metal and may be reinforced by longitudinal or circumferential wire winding which may cause initial compression in the shell. The longitudinal wire may be secured by circumferential wire 78, Fig. 18, and at both ends by welding &c. into a ring 77. The whole may be welded, metal sprayed &c. The wire may be woven into a mesh. The tubular element may be formed from rivetted or welded helical strip. The shell may comprise a number of sections fitted end to end. The shell may be lined with rubber. Pressure may be maintained by pumps, chemical action, a reservoir or a volatile liquid. Fig. 1 shows a bridge comprising two curved tubular beams 13 from which the deck 16 is suspended by cables 17. The beams may be built section by section having interfitting hemispherical ends by a crane moving on the already constructed part and longitudinal wiring attached as the work proceeds. Modified bridges comprise a single tube supporting a footway or a road externally and a roadway internally. A further modification comprises a number of tubes arranged side by side diminishing in diameter from the centre. In a suspension bridge dual towers are connected by bracing and have deck girders formed of the gas-filled shells and the gas may be helium or hydrogen. A bridge may be launched with the aid of the reaction of a downwardly directed high velocity gas jet. Floors of bridges are constructed of two sheets 66 of corrugated metal, Fig. 15, secured by bolts on clamping bars at 67 to form a series of cylinders 65 which are charged with gas under pressure. The sheets may have wire mesh reinforcement. The whole may be covered with concrete 70 bonded to the bolts 67. Hangars are formed of ribs 60, Fig. 13. and purlins 63 formed of the gas-filled shells. The Provisional Specification describes the invention applied to beams which may be thickened at places of stress and may be of plastic sheets joined by solvents.

Abstract: 740,731. Automatic exchange equipment. WESTERN ELECTRIC CO., Inc. Sept. 1, 1953 [Sept. 10, 1952], No. 24138/53. Class 40 (4). In a translator comprising coding members rotatable in accordance with the code to be translated and operable on rotation to move selected output members, the selections may be variably preset so that the translations can be readily changed as required. As shown, Fig. 1, the codes are represented by corresponding magnets 38 ... 42, 43 ... 47. Energization of a magnet, say 38, attracts the armature 48, thereby rotating the rod 22 carrying a plurality of slidably adjustable members 6. The interior surface of the member 6 is provided with a detent for co-operating with recesses 22A, Fig. 6, in the rod 22, so located that the member may be positioned either in an operative position opposite one of the horizontal bars 12 ... 21 or in an inoperative position between them. The members 6 are placed opposite the horizontal bars in accordance with the translation corresponding to the code represented by the vertical rod. Rotation of this rod causes a projection 6A of the member 6 to engage with a pin 7. on the horizontal bar 14, say, which is thereby moved to the left against the action of a restoring spring such as 64. Movement of the bars 12 ... 21 closes sets of contacts 72 . . . 81 respectively for transmitting the translation to utilization equipment. As described the translator consists of two sets of equipment as shown in Fig. 1 mounted on the front and rear sides of a supporting structure. In a modification the members 6 may be rigidly attached to the rod 22 at each crosspoint and the pins 7 are either completely removable. or capable of movement out of the line of action of the projection 6A.

Abstract: 1,262,941. Solid phase polymerization of polyethylene terephthalate. GLANZSTOFF A.G. 14 May, 1969 [14 May, 1968], No. 24500/69. Heading C3R. The molecular weight of polyethylene terephthalate is increased by heating granules of the polyester of solution viscosity 1À4 to 2À3 to a maximum temperature of 210-240 C. in a stabilized stream of a bulk layer which is moving under gravity alone and which has an inert gas passed countercurrent to it, thus after-condensation being continued until the solution viscosity is 1À6 to 3À0. The granulate used suitably has an average degree of crystallization of 30-50%. The process is suitably carried out in two stages: (i) a heating up stage in which more than the calculated quantity of hot inert gas is introduced and (ii) an aftercondensation stage in which less than the calculated quantity of cold inert gas is introduced. The inert gas may be recycled, that being used for the second stage being purified.
