Abstract: 776,997. Roofs. COOPER, D. W., and NAPPER, J. H. Nov. 23, 1955 [Dec. 28, 1954], No. 37449/54. Class 20(4)  A roof structure, whereby ground movement, due e.g. to subsidence, may be accommodated without any undue stress being imposed on the structure, is formed of a number of similar units each comprising two parallel girders 5, 6 which have their sides joined by roof beams e and their lower sides braced by transverse beams f, the upper ends of the girders 5, 6 in each unit being either rigidly, or pivotally, supported by vertical frame structures such as 1, 3, or 2, 4, according to the nature of the ground on which the structure is to be erected.; Metal strips 11 serve to cover the the roof units are rigidly secured to the supports 3, 4 but at the right hand ends, where subsidence may be expected, they are pivotally connected by bolts 7 and spherically faced nuts 9 to the upper ends of the respective side members a, b of the frame supports 1, 2 to allow for any angular movement which may occur between them. in angles 10 which are laid in a concrete The feet of the members a, b are located foundation. In a preferred pivotal supporting arrangement, Fig. 5, the uprights 12 of the support frames, of H-section, have wide angle dihedral plates 13, 14 secured to their upper and lower ends respectively, each lower plate 14, resting upon a foundation plate 15 let into a concrete foundation 16, being anchored to the latter by means of a bolt 18, a spherical washer 19, and a nut 20. Each upper angle plate 13, supporting the extended end 16a of the respective girder beam through a bearer plate 16b is connected thereto by a bolt 21, a spherical washer 22, and a nut 23. In a modification, Fig. 6, the beams f1 are slung between the adjacent girders 5<SP>1</SP>, 6<SP>1</SP> which are of the same height. In this case, where the risk of subsidence is slight, the roof sheets are fitted before the structure is raised into permanent position.

Abstract: 1,271,736. Compressed air brake systems. KNORR-BREMSE G.m.b.H. 25 July, 1969 [26 July, 1968], No. 37498/69. Heading F2F. Included in a compressed air brake system of a vehicle, especially a railway vehicle, is a relay valve device 4 which comprises a differential control piston 9, one surface 8 of which is loaded by the biasing pressure in a chamber 7 as regulated by a manually operated brake valve or pressure regulator 3; the differential surface 16 of the piston 9 is loaded by the pressure in a timing reservoir 20 which is connected through a nozzle 24 to a chamber 11 and the surface 15 which encloses the differential surface 16 is loaded by the pressure in a main air pipe 29. The control piston 9 has a valve tube 13 which has at one end a valve seat 12 co-operable with a spring loaded double-sealing plate 27 to act as an outlet valve 12, 27 to atmosphere; the plate 27 is also co-operable with a valve seat 28 to act as an inlet valve 27, 28 to the chamber 11 from a main air reservoir 1. The nozzle 24 is included in a housing wall 23 which also includes a non- return valve 25 parallel to the nozzle 24. To apply the brake the pressure in the chamber 7 is lowered by means of the pressure regulator 3 thereby displacing the piston 9 to the right to open the outlet valve 12, 27; air flows therethrough from chambers 11 and 17 and also through the opened valve 25 from the timing reservoir 20 until the equilibrium position of the piston 9 as shown in Fig. 1 is again reached. To release the brake the biasing pressure in chamber 7 is raised thereby moving the piston 9 to the left to open inlet valve 27, 28; compressed air then flows from the main reservoir 1 into chambers 11 and 17 and the piston is moved to the right to open the outlet valve 12, 27. Air slowly flows through the nozzle 24 and also through the outlet valve 12, 27 until finally the pressures in chambers 10 and 11 are equal and also equal to the pressure in chamber 7 when the equilibrium position of the piston 9 is again reached. Connected to the timing reservoir 20 is a venting valve 22.

A nuclear reactor pressure vessel is formed of hexagonal and pentagonal slabs, each comprising an outer concrete layer and an inner surface of mild steel. The slabs fit together to form an approximate sphere and may be planar or part spherical. The slabs may be held together by external flexible steel cables which also prestress the concrete in compression. Alternatively, the prestressing members may be tension rods supported within the concrete. In the latter arrangement, the tension rods are either loaded in tension after the concrete has set, by a means of a jack, or the concrete may be cast round pre-tensioned rods. After assembly the edges of the mild steel surfaces are welded together to form a fluidtight container. The container may also be formed separately and the concrete erected round it.

Abstract: 1380384 Space-monitoring system FRIED KRUPP GmbH 15 Aug 1973 [16 Aug 1972] 38551/73 Heading H4D A system for detecting the presence of a noise source within a space being monitored includes: electroacoustic receiving transducers arranged to form at least two pairs of spaced transducers, one pair being on a generally horizontal line and the other on a generally vertical line; respective AGC amplifiers connecting the transducers to the inputs of a first difference circuit giving a voltage representing the energy gradient between the horizontal pair and of a second difference circuit giving a voltage representing the energy gradient between the vertical pair; a first comparator giving an output signal if the first gradient voltage is equal to or less than a first pre-set threshold; a second comparator giving an output signal if the second gradient voltage is greater than a second pre-set threshold; and an AND gate providing an otuput signal whenever both comparator output signals are present simultaneously. In the Fig. 2 embodiment for warning a ship 15 when it moves into a danger zone centred on transducer array 1, 2, 3, 4, receiving noises from the ship, the gradient voltage for transducer pair 1, 2 decreases and for transducer pair 3, 4 increases as the ship approaches. At a predetermined approach distance both comparators will be triggered, providing an enabling signal for warning-generator 17. In alternative embodiments (Figs. 6 and 7, not shown) a third pair of transducers, on a horizontal line at right angles to the other lines, is added and its signals are processed as for pair 1, 2. For either the twopair or three-pair embodiment the gradient voltages may be differentiated with respect to time to give signals indicative of whether the ship is moving towards or away from the danger zone, these signals being logically combined with the AND gate output such that the warning signal is changed when the ship moves away (Figs. 9 and 11, not shown). The invention is applicable also to monitoring aircraft landing strips.

A self-propelled beet-harvester is mounted on rear driving wheels 4, 5 and front steerable wheels 8, 9, and has topping and digging units 15, 30 laterally offset from the front wheels so that the latter do not pass over the undug crop. As shown in Fig. 1, the machine-frame comprises parallel longitudinal beams 1, 2 supporting a cross-member 7 on which the front wheel assembly is mounted so as to be pivotable about a longitudinal axis 6a. There is also an alternative position 8a, 9a for the frontwheel assembly. A stub shaft 16 pivotally supports an arm 18 carrying the driven feeler discs 21 which are followed by a stripper drum 22 and topping knife, the tops being carried away transversely by a conveyer 24. A leaf-clearing spinner (not shown) may be mounted between the topping unit and the digging unit 30 which comprises disc-coulters 34 followed by power-driven rotary digging discs 32, 33. A flail 38 throws the beet on to a transverse elevator 39 which is turned back on itself to discharge the crop, with the aid of a deflector 40, on to a longitudinal elevator discharging into a tank 43. The tank has an apron floor 44 feeding to a transverse elevator 45, 46, for discharging purposes. In the modification shown in the drawing accompanying the complete Specification two or more power-driven digging discs 101 feed crop to the horizontal run 102 of an elevator 103, with the aid of flails 105 which throw the crop against a vertical grid 106. A weighted chain 124 hangs against the upper run of the elevator 103, and, together with a chain conveyer 128, defines an area within which the beet is tumbled before passing over the upper run of the conveyer 128 to the elevator 138 which discharges into a tank 139.
