Title: Improvements in or relating to the construction of roofs, ceilings and floors
IPC: E04B5/21
Filed: 1934-10-18
Abstract: 441,420. Roofs; floors; blocks. BIRD & CO. (LONDON) Ltd., 7, Gracechurch Street, London. Oct. 18, 1934, No. 29871. [Class 20 (iv)] A method of constructing a roof, floor, or the like, adapted to extend across two or more walls 1, 2, consists in suspending from one or more temporary beams 7 a number of substantially rectangular reinforced-concrete slabs 8, which have outwardly projecting flanges at their lower parts and are so arranged that the flanges of adjacent slabs abut or overlap to form channels in which reinforced-concrete beams are cast, the suspending elements, including the beams 7, being subsequently removed. The end rows of slabs are supported on the walls 1, 2 in recesses 3, 4 as shown in Fig. 1. A beam 7 is arranged to support each row of slabs 8 and is carried on timber baulks 5, 6 arranged on the walls 1, 2. Each slab 8 is supported by a pair of hangers, each comprising a pair of depending links 11, 12, Fig. 2, which are interconnected by a transverse link 14 and have inwardly-turned upper ends carrying rollers 15, 16 bearing on the lower flange of the beam 7. The lower ends of the links 11, 12 pass through vertical holes 10 in the slabs and are screw-threaded for engagement by nuts 18 which bear against wooden plates 17. The slabs comprise a flat upper plate having downwardly and inwardly projecting sides 8a, 8b .... provided with flanges 9a, 9b .... as shown in Fig. 4. Alternate slabs in each row are of greater depth than the other slabs so that the flanges of adjacent slabs may be overlapped as shown in Fig. 1, although in some cases all the slabs may be of the same depth. A modified form of slab is provided with the flanges 9a, 9d on two sides slightly lower than the flanges 9b, 9c as shown in Fig. 5, the plane containing the lower faces of the flanges 9b, 9c being substantially coincident with that containing the upper faces of the flanges 9a. 3d. Such slabs are arranged with the flanges 9b, 9d of slabs in the same row overlapping. With the above forms of slabs, intersecting channels are provided extending longitudinally and transversely of the structure, and after the positioning of reinforcing rods in the channels, a filling 19 of cement concrete or cement mortar is provided to form the beams. If desired, reinforced-concrete beams may be provided only in one direction of the structure, the slabs in this case being provided with flanges along two opposite sides only, the other sides of the slabs being vertical so that adjacent slabs abut along these sides. After removal of the beams 7 and hangers, the holes 10 in the slabs are filled in and a layer of earth or any other covering provided. The slabs may be reinforced by a square-shaped wire mesh member which is of substantially the same shape as the slab.

Filed: 1925-11-26
Abstract: 263,598. English Electric Co., Ltd., and Bolton, R. A. R. Nov. 26, 1925. Cut-out arrangements.-In order to ensure the opening of a feeder circuit-breaker 9 when a highspeed breaker 4 opens, on a fault occurring, and inserts a current-limiting resistance 5 in the circuit; an auxiliary coil 13 is provided to assist the overload coil 11 to open the feeder breaker, the coils 13 being connected in parallel across the whole or a part of the resistance 5. The mains are connected to a source and have a normal speed breaker 3 in the + lead, which is connected to the bus-bar 6, the high-speed breaker being in the - lead. On the occurrence of a fault in, for example, feeder T, the breaker 4 opens and inserts the resistance 5, so cutting down the current, which may not be strong enough to bring out the breaker 9. Owing to the P.D. across the resistance 5 the auxiliary coils are energized to assist the ordinary coils, but only in the feeder (in this case, 7) carrying the abnormal current will the combined effect be strong enough to open the breaker 9. The coil 13 is arranged to be disconnected when the feeder breaker opens.

[Class 106 (ii)] Comprises a plurality of Bourdon tubes which are exhausted to a substantial degree and sealed and all connected to impart movement to indicating means. A number of Bourdon tubes, in Fig. 1, three of the same length, have their closed ends 12 integral and their open ends affixed to a drilled member 14 through which their interiors are placed in communication with a pipe 15 through which they are exhausted and which is sealed off as shown. The free ends are connected with the common indicating mechanism. They may not be of the same length and in this case the difference is taken up by shaping the member 14 accordingly. They may vary in cross-section, wall thickness, and transverse dimensions. Thus the tubes differ in natural frequency and notwithstanding this may be so chosen that their free ends shall all move to the same extent. Alternatively the free ends may tend to move differently and thus resist the effects of vibration.

Title: Improvements in the manufacture and production of red chromate pigments
IPC: C09C1/20
Filed: 1932-10-28
Abstract: Red pigments comprising mixed crystals of lead chromate, lead sulphate, and at least 4 per cent by weight of lead molybdate are precipitated by the addition to aqueous solutions of lead salts of strongly acid aqueous solutions containing sulphate, chromate, and molybdate ions, and at least 1 hydrogen ion per atom of lead to be precipitated.  Part of the lead may be replaced by barium and/or strontium, and part of the molybdate by tungstate.  It is preferable to employ alkali bichromates and sulphuric or molybdic acids, but monochromates and sulphates may be used with mineral acids such as sulphuric, hydrochloric, or nitric, or organic acids such as acetic. Precipitation may be effected at ordinary or elevated temperature, and the acid neutralized after the precipitation.  The content of chromate is usually not less than 30 per cent.  Suitable additions, for example hydrate of alumina, may be made to the precipitate or before precipitation.  Examples describe the precipitation of lead chloride, nitrate, or acetate solutions, which may also contain barium chloride or nitrate, with solutions containing potassium chromate or bichromate, ammonium molybdate, and sulphuric acid and/or alkali sulphates, and in some cases nitric or acetic acids. Specification 369,916 is referred to.  The Provisional Specification is not limited to crystals whose lead molybdate content has a lower limit of 4 per cent.
