Title: Means for Driving Fasteners into High-Strength Materials
IPC: F16B19/14
Filed: 1967-07-25
Abstract: 1,162,596. Fastener driving tools. HILTI HANSA G.m.b.H. 25 July, 1967 [1 Aug., 1966; 2 May, 1967], No. 34113/67. Heading B4C. A device for driving fasteners, such as nails or studs, into hard material 10, such as steel, comprises a thrust member 11 movable in a barrel 1, a fastener 7 and a deformable obturator piece 9 which when the fastener is driven therein deforms in a direction opposed to the driving-in direction until limited by the thrust piece, the muzzle of the barrel be shaped so as to prevent radial deformation of the obturator while the fastener is being driven in.

Title: Improvements in the manufacture of metal tubing
IPC: B21C37/09
Filed: 1935-12-11
Abstract: 455,407. Making tubing. HEILBUT, M. H., Kennan's House, Crown Court, Cheapside, London.-(Bundy Tubing Co. ; 4815, Bellevue Avenue, Detroit, Michigan, U.S.A.) Dec. 11, 1935, No. 34309. [Class 83 (ii)] In a method of making high-pressure tubing coated strip stock is used to form a number of tube members the edges of which are sealed by fused metal and these are disposed in telescoped relation and drawn down in size until the contiguous surfaces thereof tightly contact, the combined tube being then heated to unite the said surfaces by fusing the interposed coating metal. The coated tubes to be telescoped are preferably of the two-ply kind having an offset 3 against which the ends 4, 5 abut, copper-coated steel strip being suitable for making such tubes. Three tubes capable of being easily telescoped are fitted together and one end 17 of the composite tube thus formed is swaged so that it may be passed through a die 15 at the commencement of a drawing operation, Fig. 8. The composite tube is subsequently passed through a heating furnace 20, and cooler 21, Fig. 9, the former supplied through a pipe 22 with a non-oxidizing gas, with the result that the surfaces of the separate tubes are copper-welded together. The tube may thus be regarded as completed or it may be subjected to a further drawing process and annealed. Specifications 369,982 and 387,968 are referred to.
Patent GB-792685-A (GB)
Title: Travelling crane
IPC: B66C23/36
Filed: 1955-11-30
Abstract: 792,685. Mobile cranes: EMANUEL, G., and EMANUEL, R., [trading as EMANUEL DI E R. EMANUEL & C. SOC. IN ACCOMANDITA SEMPLICE]. Nov. 30, 1955 [Dec. 2, 1954; Dec. 14, 1954; Jan. 5, 1955; Sept. 30, 1955], No. 34318/55. Class 78 (4). A portable gantry for lifting gear is supported at one end by a leg 1, Fig. 2, supported by wheels 6 and at the other end by legs 9 which can be raised from the ground and moved relatively to the gantry: this movement permits the legs 9 to clear part of the load, e.g. the wings V of an aircraft to be lifted. In the construction of Fig. 2 the legs 1, 9 are in pairs and the legs 1 are connected to a tractor 4 by a member 7 and by a pair of longitudinals 3 which straddle the nose of the aircraft. The legs 9 fold upwardly and forwardly about hinges below the beam 8 which can be slid back to overlie the member 7 when the lifting tackle 12, 12 is not in use. In the construction of Fig. 7 a pair of legs 21 can be folded by a ram 29 to lie against the beam 19 of the gantry which is turned about a hinge 20 on a column 15 by a ram 28. The column 15 can be luffed about a hinge 16 by a worm and wheel 24, 25 and is carried by a turntable 17 so that the gantry 19 can be turned through 180 degrees from the position shown and then, by conjoint operation of the worm drive 24, 25 and of the ram 28, may be lowered, while still horizontal to rest on the chassis 13 of the vehicle. The column 15 is normally stayed by a hinged back stay 26, 27 from an extension 17a of the turntable. In the construction of Fig. 8 a pair of gantry beams 55 are carried by vertically sliding collars 54 on transversely spaced posts 53 and are guyed by tackle 58. The front ends of the gantry beams 55 may be raised and lowered by hydraulic rams and the rear ends carry hydraulic rams 61 which can be folded about a pivot 63 by rams 61a to lie against the gantry beams. When not in use the gantry beams 55 can be swung about the column 53 to extend forwardly to rest on a portion 56 of the vehicle chassis. In a construction similar to that of Fig. 8 the gantry beams 55 can be locked in their rearwardly extending position by members operated by hydraulic rams. The tackle 58 may be operated by hydraulic rams carried on the beams 55. In the construction of Fig. 20 the transversely spaced beams 111 of a gantry may be pivoted about the rear axle of a tractor 114 by jacks 116 carrying wheels 117. This raises wheels 118 on legs 113 sufficiently high to clear the wing of an aircraft when the legs 113 are slid rearwardly along the beams 111. The tackle carried by the gantry beams may comprise stationary tackle, carriages running along the gantries, or carriages running on bridges extending between twin gantry beams and movable with carriages running on the beams. Dual controls for opposite directions of travel may be provided on the tractor vehicle.
Patent GB-343086-A (GB)
Title: Improvements in concentrating the water-soluble vitamin of a material containing such vitamin
Filed: 1929-11-13
Abstract: Water-soluble vitamins are extracted from parent materials by means of a dilute acid, and in the solution thus obtained there is dissolved an organic substance which, on substantially neutralizing the solution, forms a voluminous precipitate which carries down the vitamins; the precipitate is then separated from the solution, and the vitamin is separated from the precipitate. Instead of a single organic substance, two substances, which on neutralization form a voluminous organic precipitate, may be added to the solution, for example, a sugar such as saccharose, dextrose, or levulose and a calcium compound such as the hydroxide or carbonate.  On stirring the voluminous precipitate so formed with water, alcohol, or a mixture thereof, and adding a suitable inorganic acid such as sulphuric acid, the calcium is separated as the insoluble sulphate, and the remaining solution may be further treated to concentrate the vitamin contained therein.  In an example, brewers' yeast is allowed to stand for some months with 10 per cent acetic acid.  To the extract calcium carbonate and either saccharose, dextrose, or levulose are added. The solution is then neutralized with caustic soda or potash solution, or preferably the solution is nearly neutralized with calcium hydroxide, and the neutralization completed with a 1/2 to 1 per cent solution of caustic soda or potash.  The precipitate of sugar-calcium is separated, stirred with water, and 5 to 10 per cent sulphuric acid is then added in not more than the quantity required to separate the calcium as calcium sulphate.  Ethyl alcohol is added, and the solution is decanted from the precipitate.  The alcohol is removed by distillation, and the solution is concentrated in a vacuum, whereby an emulsion is obtained.  The vitamin extract is obtained as a semi-solid mass either by centrifuging, or by allowing the emulsion to deposit it in the form of drops on the surface of the vessel in which the liquid is concentrated.

Filed: 1930-11-19
Abstract: 367,392. Friction ratchets. OLIVER; A. V., 2, Norton Way, Letchworth, Hertfordshire. Nov. 19, 1930, No. 34803. [Class 80 (iii).] In friction ratchet gearing, the wedging members 5, which may be rollers or balls, are adapted to engage either the driving or driven element 1 and recesses 8 in a free or floating element 3. The members 5 are housed in the driven or driving element 2 or in a part connected therewith. The positions of the parts 1, 3 may be reversed. In the form shown a ring element 3 is connected with the element 2 by a helical spring 9, which initiates the gripping action. Alternatively, the ring 3 may be a spring fit over the rollers, or a radiallyacting force may be applied to the ring, or the rollers may be resiliently loaded. When the spring 9 is omitted, a stop may prevent the rollers from moving past the middles of the recesses 8.
