IPC: B64C1/06
Filed: 1919-11-18
Abstract: 153,180. Thurston, A. P. Nov. 18, 1919. Framework.-Relates to thin metal structures of the kind comprising four hollow booms connected to a central hollow member adapted for resisting bending moments about two axes at right angles, m addition to compression and torsion, as in spars and longerons for aircraft, and consists in connecting each of the booms separately to the central member by a single strip, web or flange member, either integrally or built up therewith. In a modification, three hollow booms may be used. Two strips of metal with corrugations are rolled with hollow booms a, Fig. 1, at each edge, the strips being placed back to back to form a central member b, with the booms a connected thereto by an integral strip c. The booms are completed by riveting at f. Extra corrugations in the metal strips may be used, in which case the central member is formed of two or more tubular portions, and the booms may be separately constructed and riveted to the web connexion c. In a further modification, the corrugated plates forming the sides of the web b are distanced and connected by flange members to which the booms also are attached. In the arrangement shown in Fig. 4, the web is made in two parts connected at the flanges e, and the flange c connecting the booms to the web is integral with a pair of booms. lnternal positioning strips placed at suitable intervals connect the flanges e. The material of the central member may be different from that of the booms.

Title: Improvements in controlling apparatus for servo-brake mechanism for automobiles
IPC: B60T13/24
Filed: 1928-10-06
Abstract: 323,754. Whitehead, A. J. Oct. 6, 1928. Fluid-pressure; covers and protectors for brakes; personal actuation. - A fluid-pressure brake for automobiles in which the foot pedal has direct connection with the brakes during the whole of its stroke comprises reciprocating valves n, p actuated by a rocker D controlled by a rod 4<a> operated by the eccentric 2<a> mounted on the spindle b<1> which carries a channel section lever B containing the trip levers 6 within which is mounted the roller 7 that contacts with a lever A mounted on a spindle a<1> connected to the brakes and also by the lever 10 to the fluid pressure motor d. Between the eccentric strap 3 connected to the rod 4a and the concentric 2<a> is arranged an eccentric sheath 2 to which is fixed a lever C carrying spindles 4, 5. The spindle 4 is supported also in the lever B and carries the links 6 which support the other end of the spindle 5 which carries the roller 7 engaging the lever A. The eccentric 2<a> causes longitudinal movement of the rod 4<a> to operate the valves n, p and also causes a movement of the sheath 2 relative to the shaft b<1> and thus causes a slight movement of the lever C and the spindle 5 about the spindle 4 in a direction opposite to the movement of the lever B about the shaft b<1>, then for a small movement of the shaft allowing operation of the valve without direct operation of the brakes by the lever A and yet maintaining the roller 7 in contact with the lever A. The valve n operated by a spindle g controls the suction pipe i and is mounted on a hollow stem k enclosing the stem m of the atmospheric valve. p. The rocker D oscillates on an eccentric adjusted by means of a spindle u. In order that a reactionary effect may be applied to the brake pedal the lever C is directly connected by a chain passing over a. pulley to the plate 12 of the diaphragm e of the fluid pressure motor. The diaphragm e is connected to the brakes by means of a one-way connection comprising projections 8, 9 on the bosses of the levers A, 10, respectively, which permits foot application of the brakes without depressing the diaphragm e.
Patent GB-211912-A (GB)
Title: Improvements in dyeing
IPC: D06P1/44
Filed: 1922-10-24
Abstract: Textile fibres and fabrics are dyed by means of mineral pigments, produced on the fibre in the colloidal form by the interaction of a plurality of reagents in presence of a protective colloid.  The colour is then fixed by coagulating the colloid by chemical, physical or electrochemical means.  In the case of chemical coagulation, the coagulant may be applied to the fibre before or after the pigment-forming reagents.  In an example, cotton, impregnated with a solution of ferric chloride containing sugar or glycerine, is acted upon by ammonia vapour and subsequently treated with hydrogen peroxide solution and dried by air or oxygen.  In this example in place of ferric chloride there may be used other soluble iron salts, such as sulphate, oxalate, formate, ethylsulphate, or salts of organic acids containing a benzene nucleus, or salts of other metals, such as copper sulphate, or salts of zinc, cadmium, cobalt, nickel, lead, antimony, tin, manganese, chromium, calcium, barium or aluminium and the impregnation may take place under pressure; the ammonia may be replaced by other alkalies, by hydrazine hydrate, or by sulphuretted hydrogen with or without air or oxygen, by carbon dioxide, thiocyanic acid or its salts, potassium ferrocyanide or ferricyanide, chromates, or other compounds; the protective colloid may be a salt of lysalbinic acid or a decomposition product of a protein, such as gelatine; the final stage of the process may be effected by auto-oxidation, or by means of ozonized air or per-salts, such as perchlorates; and the coagulation may be by means of ultra-violet light or electrolytic by passing the impregnated material over a conductive roller supplied with current.  Treatment with tannin, aldehydes, amines, or sulphonated oils improves the colour.  The protective colloid may in addition be one of the pigment-forming reagents and may itself be coloured.  Such bodies are colloidal metal salts, such as resinates, naphthenates, or oleates, and colloidal metals containing protective colloids and they may react with metal salts, such as permanganates, ferrates, vanadates, pertitanates, bichromates, &c.  An example shows the dyeing of viscose silk by successive impregnation with solutions of sodium permanganate and sodium, copper, or cobalt oleate.  Another example shows the production of an olive-brown to black on wool by successive impregnation with a colloidal solution of copper containing a protective colloid and with sodium ferrate, followed by coagulation by heat.  The Provisional Specification describes also the use of the process for dyeing funs, leather, cellulose esters, wood, paper, &c., the use as pigment-forming reagents of the metallic, such as iron, compounds of tannic and gallic acids, of pyrogallol and of synthetic tanning agents such as those from phenol formaldehyde, and the use as precipitants of organic anhydrides and includes also the formation on the fibre of half-mineral half-organic bodies.
