Title: Improvements in or relating to anti-vibrational mountings for instruments and the like
IPC: B64D45/00
Filed: 1928-05-30
Abstract: 312,808. Chaffer, C. May 30, 1928. Magnetic compasses. - In an anti-vibrational mounting for a magnetic compass, the frame carrying the instrument is connected to an outer supporting frame by at least one pair of substantially parallel horizontal wires &c. which are spaced apart, are attached at their ends to one of the frames, and are connected at about their centres to the other frame, so that each pair of wires permits slight relative movement of the connected parts in a direction at right-angles to the length of the wires while preventing such movement in the direction in which the wires extend. In the form shown two pairs of wires approximately at 90‹ to each other are provided, the instrument-carrying frame A being connected to an intermediate floating frame D by one pair C, C' which are attached at their ends to the frame D and at their centres to projections B, B<1> from the frame A. The frame D is similarly connected to the outer supporting frame H by the second pair of wires G, G<1>. The wires are adjusted so as to be just not tight. For supporting heavy instruments the wires may be replaced by ribbon springs arranged with their broad faces vertical.

Abstract: 728,837. Flexible hoses. DUNLOP RUBBER CO., Ltd. May 15, 1953 [June 25, 1952], No. 15925/52. Class 99 (2). In a hose a comprising a helical reinforcement c of wire or other resilient material enclosed in a flexible impermeable corrugated tube a<SP>1</SP>, e.g. of natural or synthetic rubber, the corrugations of the tube extend between the coils of the helix to hold those coils apart and to form a smooth bore when the hose is in an unextended and undistorted form. The tube is free to extend by a reduction in depth of the corrugations and on extension of the helix. In making the hose, a tube a<SP>1</SP> of unvulcanised rubber mounted on a mandrel is wrapped with a strip of rubber-impregnated fabric cut on the bias and which after cleaning of the outside thereof with a rubber solvent is coated with rubber solution. A length of tubular stockinette is fitted over the fabric, the assembly then being wrapped to consolidate the construction, partially vulcanised and removed from the mandrel. After removal of the wrapping, the tube is passed over a coil c, for example of galvanised steel wire, and secured to the end turns of that coil which itself is attached to a resilient cuff e prepared on a tubular sleeve f mounted on a second mandrel j. The convolutions of the coil are in contact or slightly spaced apart. The tube is then wrapped with string k to force the wall of the tube between the convolutions of the coil and the free end of the tube is fitted with an end cuff l which is rotated on the mandrel j to correct the pitch of the convolutions of the coil. The completed hose is then spirally wrapped and vulcanised, the wrapping and string afterwards being removed.

Abstract: 375,518. Loft ladders. BARRACLOUGH, G. H., 11, Redburn Drive, Shipley, near Bradford. June 4, 1931, Nos. 16219 and 19960. [Class 20 (ii).] Relates to collapsable stairways of the lazytongs type, of the kind which can be accommodated within a hatch opening when in the collapsed or inoperative position. According to the invention, the sides and back of the stairway are formed with lazytongs or lattice bars F, N, respectively, Figs. 1 and 2, the side lattice bars being connected to brackets D attached to the hinged or pivoted hatch cover E. In the form shown, the brackets D pivot about a transverse rod C, the extremities of which are journalled in brackets B secured within the hatch opening A. One of the uppermost pair of side bars F on each side carries an antifriction roller K which engages in a slot J in the bracket D. The other uppermost bars are pivoted to the rod C. The lowermost bars are interconnected by transverse angle-irons, rods, or bars M. The lattice bars N are pivoted centrally together about pins H<1> each of which carries a bracket P housing a pin G<1> on which pivots a second bracket R. Each bracket R is secured to a step or tread L the ends of which are connected in known manner to the advance portions of the bars F. To facilitate the opening and closing movements, overhead balance weights are connected to the stairway and cover by wire cables U, W, respectively. The cable U passes over overhead pulleys and around a pulley V, and is secured at the lower end to a bracket S carrying a bifurcated hook T. This hook is provided to receive the doll-head of a rod which is used for pulling down the stairway. In a modification, the cover E is hinged directly to the side of the hatch opening, the brackets B are dispensed with, and the rod C is carried by the brackets D.

The walls may be formed by the outermost labels of opposed stacks 26, 36 held a short distance from the cup by stops whereby the shot extends slightly from the opposed faces of the cup. The downward thrust on the upper stack is greater than the thrust on the lower one so that the latter is forced downwardly by the material supplied and operates a switch 60 to halt the extrusion. The shot with upper and lower labels attached is swung with the cup horizontally to a pressing station.
Patent GB-671403-A (GB)
Title: Improvements in or relating to intensive processes for the manufacture of sulphuric acid
IPC: C01B17/86
Filed: 1949-06-20
Abstract: <PICT:0671403/III/1> In the intensive production of sulphuric acid wherein nitrous sulphuric acid is circulated in parallel through all the reaction towers and part of the acid produced therein is denitrated by the action of sulphur dioxide, heat and water to yield the product acid, the acid circulated through the reaction towers is a highly nitrous sulphuric acid, which reacts like nitropersulphuric acid, dissolved in sulphuric acid, the solution being of 61-65 DEG B<\>ae and containing 5-12 per cent of nitrous compounds by weight calculated as N2O3.  The sulphur dioxide is contacted with the nitrous compounds in such amounts that the ratio of nitro-sulphuric compound (regarded as (SO4NO3)2 4H2O) to SO2 is not less than 12 to 1 whereby nitrous oxides are not reduced below N2O3.  The illustrated apparatus comprises a concentrator C, two denitrators d1, d11, reaction towers r1, r11, r111, and filter towers f1, f11.  The circulation of the acid is effected through two closed circuits, one comprising the reaction towers, the other comprising the concentrator, the denitration towers and the filter towers, the circuits being linked by a conduit through which nitrous acid is withdrawn from the reaction towers and passed to the first denitrator.  The sulphur dioxide passes successively through a concentrator C to which sulphuric acid from denitrator d11 is fed by pipes 20, 21, the denitrators in parallel, the reaction towers and finally to the filter towers where it is freed from residual nitrous gases by acid from the concentrator through lines 16 and 12, and from the first denitrator, the acid being returned via pipes 13 and 14 to d1.  Nitrous acid is withdrawn from the reaction tower circuit 17, 6, 7 by pipe 8 and passed to d1, the effluent therefrom passing to d11 through pipe 10.  Product acid is withdrawn at 19.  Specifications 643,394 and 667,901 are referred to.

In a refrigerating machine of the reversed hot-gas engine type, working medium can flow from the working space during the expansion stroke and to the working space during the compression stroke. As shown in Fig. 1, working piston 4 descends during the expansion stroke to compress gas in auxiliary space 11 and force it through non-return valve 13 and cooler 20 to chamber 14 from which it is admitted at an appropriate time during the compression stroke of the piston to the working space 6 through controlled valve 15. Also during the expansion stroke, gas flows through controlled valve 17 to chamber 18 whence it flows into the auxiliary space 11 through non-return valve 19 during the compression stroke of the piston. As shown in Fig. 2, two machines work in antiphase, the auxiliary spaces 37, 39 being connected by pipes 38, 40 to the working spaces 33, 34 respectively so that in each machine, the working space receives gas compressed in the auxiliary space of the other machine during the compression stroke of the former and the auxiliary space of one machine receives gas from the working space of the other machine during the expansion stroke of the former.
