An airport gangway 2, comprising telescopic sections, has one such section 4 suspended in a portal 5 mounted on a truck chassis 10 provided with two assemblies of road wheels 24 spaced transversely of the length of the gangway, and the section 4 is guided in the portal 5 for up and down movement relative thereto, via hydraulic jacks 11 on the chassis 10, by guide means comprising upper and lower guide rollers 8 and 9 on the section 4 engaging opposite guideways 6, one on each side of portal 5, the guideways being of arcuate configuration with the centres of curvature lying substantially on the horizontal pivotal axis 7 of the gangway 2 on a pedestal 1 on which it is supported, so that the orientation of the portal 5 is substantially constant in all vertical positions of the section 4. Each of two pairs of the road wheels 24 is mounted on an axle casing 22 having a yoke 20 including horizontal trunnions 18 extending transversely of the longitudinal axis of the casing 22 and rotatably secured in a bearing block 16 carrying a disc 14 or 14<SP>1</SP>, and a disc 17 which bears against a disc 12 on the chassis 10, so that the entire assembly is rotatable about a substantially vertical axis 13. Disc 14 is larger in diameter than disc 14<SP>1</SP> and both discs are lapped by an elongated drive element e.g. a cable 28 or a chain, secured to a peripheral point on each disc and having its ends secured to an hydraulic piston in a cylinder 30 secured at 32, 32, in the chassis 10 so that actuation of the cylinder 30 rotates the wheel assemblies in the same sense at different speeds, thereby enabling both the longitudinal axes of the axle casings to extend substantially through the vertical pivotal axis of the gangway on the pedestal 1 for true rolling movement of the wheels 24 when so pivoting the gangway. The relative direction of rotation of the wheels is thereby unaltered e.g. when going from elongation to rotation of the gangway.

[Also in Division E1] The electrical control circuit of an automatically regulated, cyclically operable drag line scraper system for a batching plant has a contact that controls the scraper bucket haulage motor 10 of the system in dependence upon the resistance encountered by the scraper bucket to its passage. Preferably the contact 52 is a relay the coil 35 of which is traversed by current proportional to the current supplied to the motor and is associated with a resistance 38, 41-45 of fixed or variable value, said resistance being connected in parallel with the coil 35 by a contact 39 of the relay when the relay is energized. The variable resistance allows of appropriate adjustment of the circuit control factors when the system is to handle more than one material as in a batching plant when sectorarranged storages boxes are to be filled with different materials. Preferably the contact causes reversal of the motor 10 immediately the scraper bucket breaks out of the top of material after having passed through the material. Switches 53, 54 are so connected in parallel with the contact 52 as to bridge the contact to allow entry of the bucket into the material. A limit switch 32 prevents overtravel of the bucket at the upper permissible limit of its travel.

Abstract: 1,251,337. Filament-containing foam structures. IMPERIAL CHEMICAL INDUSTRIES Ltd, 18 Feb., 1969 [28 Feb., 1968], No. 9636/68. Headings C3B, C3C, C3P and C3R. Foam structures containing continuous strands are prepared by forming a three dimensional assembly of continuous strands, a proportion of the strands being structural strands and the remainder being filler strands, the structural strands being arranged at or near the surface of the assembly and the filler strands being arranged in the central region of the assembly, contacting the assembly with a synthetic foam precursor material and processing, moulding and solidifying the precursor material incorporating the strands, the strands being aligned in a substantially parallel manner and distributed throughout the cross-section of the structure. The structural strands are those having a high tensile modulus, for example staple fibre yarns, glass filaments, and polyamide or rayon fibres or filaments and the fibre strands have a tensile modulus which is low in relation to the tensile modulus of the structural strands, for example, jute, polypropylene or polyamide yarn and fibrous waste spun into yarn. The structural strands may be coloured to contrast with the colour of the foam material. Particularly useful as the foam constituents are polyurethane foams and those based on vinyl ureas, phenol-formaldehyde, urea-formaldehyde; melamine-formaldehyde, polyesters, polyolefins, polyamides, polystyrene and epoxy resins. In a typical example a warp of glass continuous filaments is wetted with a polyurethane foam precursor mixture and cut to form a bundle. Part of the bundle was placed in a mould and a square channel was produced along the length of the sample. A hank of nylon filaments wetted with the same precursor mixture was laid in the channel made in the glass filaments and the remaining part of the bundle of glass filaments was placed on top of the nylon filaments. The mould was closed and the precursor was foamed round the filaments.
