Title: Improvements in or relating to aircraft such as aeroplanes and the like
IPC: B64C25/44
Filed: 1933-07-04
Abstract: 409,163. Aircraft wheel-braking systems. BOGGIO, A., 17, Via Insegnamente, Milan, Italy. July 4, 1933, No. 18942. [Class 4.] Frictional resistance to rotation of a tail wheel is utilized to produce the force for braking the landing-wheel brakes of an aircraft having landing wheels and a tail wheel. In one form, actuation of a lever mounted on an aircraft control, expands through a Bowden cable 3 and a lever 9 articulated on a disc 5 mounted freely on the tailwheel axle, a brake-shoe 8, mounted on the disc 5, into engagement with a brake drum provided on the wheel 4. Subsequent rotation of the wheel 4 and disc 5 effects through a second Bowden cable 6 having one end secured to the disc, actuation of the landing-wheel brakes. In a modification, the cable 6 operates, against a spring, the piston of a hydraulic cylinder to force fluid to a distributer 17, Fig. 7, to force apart two spring- pressed pistons 19 to supply fluid through pipe connections 21 to the brakes. A cam 22 between the pistons is connected through a lever 23 and a link 24 to the rudder bar 25 to facilitate differential application of the brakes. Pipes 26, 27 and 28 and a four-way valve 29 facilitate recharging the distributer 17 with fluid. In a further modification, an air pump may replace the hydraulic cylinder or the cable 6 may be connected to a valve interposed in a connection between a reservoir and the brakes. In another form, actuation of a lever 1<a>, Fig. 8, applies, through a cable 3<a1>, a lever 99 and a cam 53 the landing-wheel brakes and at the same time through a cable 3<a> and a catch on a lever 103 locks two telescopic cylinders 104 connected at one end to a lever 105 which actuates a cam to apply the tail-wheel brake. Thus when the tail wheel contacts with the ground, a shock-absorber strut 108 telescopes causing lever 105 to expand shoes 110 which expands through balls 112 a split ring 113 faced with friction material and normally held inoperative by springs into engagement with a brake drum on the wheel 4. The ring 113 tends to rotate on the shoes and moves with it a pin secured by a cable 6<a> to a lever 119 which actuates a cam 54 to apply further the landing- wheel brakes. In a modification of this latter construction, actuation of a hand-lever forces oil from a distributer to partly apply the landing-wheel brakes and through a cable locks the telescopic cylinders applying, when the tail wheel touches the ground, the tail-wheel brake causing rotation of the ring which in this case is connected to a piston to displace fluid from a cylinder to apply further the landing-wheel brakes. In a further modification operation of a hand lever locks the telescopic cylinders and opens a valve to allow compressed air to pass from a reservoir to a distributer to partly apply the landing-wheel brakes. When the tail wheel contacts with the ground a further valve is actuated through a cable to open a second valve to supply further the distributer with compressed air and thus further apply the brakes.

Title: Process of and apparatus for the thermal decomposition of metal salts or mixtures thereof
IPC: C01G1/00
Filed: 1936-07-08
Abstract: <PICT:0477617/III/1> Concentrated solutions, suspensions, or aqueous melts of metal salts are decomposed by atomizing them into an elongated decomposition chamber and bringing them into intimate contact with a highly heated gaseous medium which effects dehydration and decomposition.  The amount of gaseous medium used and its initial temperature are such that the products of decomposition which are entrained by the gas leave the chamber at temperatures still in the vicinity of the decomposition temperature.  Metal salts which may be decomposed include the sulphates of silver, iron, manganese, copper, nickel, cobalt, zinc, and magnesium, the chlorides, nitrates, and carbonates of the heavy metals, the nitrates and carbonates of the earth, alkaline-earth and alkali metals, and magnesium chloride.  The solutions &c. may be atomized by compressed air steam, or other suitable gas, whilst the gaseous medium may be gases of combustion, air, carbon dioxide, nitrogen, or superheated steam and it may be used at temperatures up to 1800 DEG  C.  In the decomposition of sulphates, sulphuric acid or oleum may be recovered from the issuing gases.  As shown in the drawing, the salt solution &c. is atomized through the nozzle 22 and mixes in the chamber 21 with gases of combustion supplied from burners 23.  Further heat may be supplied by means of burners 26. The issuing gases are freed in a cyclone separator 31 from solid products, partly cooled in a waste heat boiler 30, further cooled in a heat-exchanger 33 which serves to preheat air supplied to burners 23, 26, and finally passed through an electrical gas cleaner 35.  In other methods of carrying out the process, the gaseous heating medium may be recirculated after separation of solid and gaseous products of decomposition and reheating.

Title: Improvements in or relating to the recovery or separation of metals
IPC: C22B15/00
Filed: 1919-07-31
Abstract: The production of one salt from a mixture of oxides such as that obtained by roasting a sulphide ore is effected by submitting the mixture to the action of a gaseous acid radical under such temperature and with such pressure of the acid radical as will effect the preferential reaction desired.  The invention is described in connection with the treatment of a mixture of copper and iron oxides obtained by roasting copper pyrites.  This mixture is heated with sulphur trioxide under the necessary conditions at a temperature of about 620-700 DEG  C., when copper sulphate alone forms.  The invention is applicable to the formation of other salts such as chlorides, and to the treatment of various mixtures of oxides.  The separation of copper and nickel and the extraction of aluminium salts from bauxite or other materials are mentioned.  In a similar manner a mixture of salts of the same acid radical may be treated in order to effect the decomposition of one but not of the other.

Title: Process for forming or shaping a metal substrate
IPC: C10N50/02
Filed: 1974-05-01
Abstract: 1473235 Lubricants USS ENGS & CONSULTANTS Inc 1 May 1974 [18 May 1973] 19139/74 Heading C5F [Also in Divisions B2 and C3] A metal substrate is lubricated during a forming or shaping step by a two-component coating applied beforehand from an aqueous dispersion and then dried. The first component is a copolymer of ethylene which forms a film adherent to the metal, e.g. a copolymer with acrylic acid, methacrylic acid, crotonic acid, salts and esters of these acids or vinyl acetate, or a terpolymer. The second component is a lubricant that is substantially insoluble in the copolymer and is an animal, vegetable, mineral, or synthetic oil, a fat, a soap, a fatty ester, a grease, a wax, or a mixture of these. After forming, the coating may be removed by cleaning with an alkaline detergent. The dispersion may contain enough alkali to form a watersoluble or dispersible salt or ionomer of the copolymer; this alkali may be ammonia or an aromatic amine, which will volatilize in the drying step. It may also contain a solid lubricant, e.g. graphite, MoS 2 , carbon monofluoride, PTPE, nylon, talc, mica, oxide pigment or kaolin clay. The compositions used in the examples comprise: as first component, an ethylene-acrylic acid copolymer by itself or with polyvinyl alcohol or with both polyvinyl alcohol and an ethylene-methacrylic acid copolymer partly neutralized with sodium hydroxide; as oil phase, mineral oil alone or mixed with lard oil, or lard oil mixed with oleic acid or ammonium oleate; they also contain added surfactants, and two have added fillers, MoS 2  in one, talc or iron oxide in the other.

Abstract: 1,069,447. Filling tanks. LIQUID GAS ANLAGEN UNION G.m.b.H. May 7, 1964 [May 7, 1963; Dec. 10, 1963], No. 19142/64. Heading B8T. An installation for transferring a low-boiling liquid e.g. propane or butane, to or from a container therefor, e.g. a ship's container 1, under varying conditions of temperature and pressure, includes heat-exchangers 2 and 4, a compressor 3 and a pump 5, and associated pipe lines and valves. One side of the heat-exchanger 4 is connected either to the heated cooling water of the ship's engines or with cold sea water, to provide a heating or cooling of the low-boiling liquid. The pump 5 may draw liquid from the container 1 through the heat-exchanger 2 and deliver it via a valve 35 to containers on shore. Liquid from shore containers at a relatively high or low temperature may be supplied through pipe lines 12, 15 to the ship's container, and is cooled or heated respectively so that the liquid stored is at a sufficiently low temperature to obviate the need for high-pressure storage containers. When relatively high-temperature liquid is fed to the container 1, the vapours formed are drawn by the compressor 3 through the heat-exchanger 2, operating as a liquid trap, and condensed and liquefied in the heatexchanger 4, the condensed liquid then passing back to the container via a control valve 11. When relatively low temperature liquid is taken on board, it is fed to one side of the heatexchanger 4 and heated, the vapours being sucked into the compressor and passed to the heat-exchanger 2 which condenses it. The liquid levels in the exchangers 2 and 4 are adjusted by devices 21, 23 and 20, 22, respectively. In order to evacuate ships' containers to low pressures, the installation may include a three-stage compression set connected to three heat exchangers. In a modified installation two compressors are utilized, and a separate refrigeration circuit of ammonia is provided between the two heat-exchangers, and the condensation heat of the circulated ammonia is given up to cold sea water supplied to the one heat-exchanger.

Abstract: 837,603. Clocks. JUNGHANS, H., and JUNGHANS A.G: GEB. June 21, 1956 [June 22, 1955; Sept. 14, 1955], No. 19301/56. Class 139 In an alarm clock having one spring for driving the going train and the alarm train, the mechanism for determining the duration of the alarm also varies the intensity of the sound. In the first example, Fig. 1, the going train is driven from the barrel and the alarm train from the barrel arbor 12 through a pawl and ratchet clutch 18, 19. A lever 33, Fig. 6, frictionally mounted on the arbor 12 controls a rocker member 30 the arm 30e, Fig. 1, of which co-operates with the alarm hammer 27, 28 to which the alarm anchor 26 is connected. A holding spring 32 co-operates with the rocker 30. The arrangement is such that when the alarm is released, the arm 30e at first limits the travel of the hammer 27, 28, and as the spring unwinds, the lever 33 moves the rocker 30 so that the arm 30e no longer limits the 'travel of the hammer 27, 28. On the continued unwinding of the spring, the lever 33 again moves the rocker 30 so that the arm 30e finally locks the hammer 27, 28. In the second example, Fig. 11, the alarm hammer 139 is controlled by a cam 137 frictionally mounted on the spring arbor 113. The hammer 139 initially has a limited movement, then full movement and is finally locked. In a modification, Fig. 13, a one-toothed gear 201 frictionally mounted on the spring arbor 113 drives a gear 202 which controls the alarm hammer 139. Reference has been directed by the Comptroller to Specification 698,810.
