Title: Improvements in and relating to the governing of surfaces moving within a non-rigid medium
IPC: B63H25/38
Filed: 1921-03-19
Abstract: 175,233. Flettner, A. Feb. 10, 1921, [Convention date]. S c r e w propellers; paddle-wheels; rudders; steering - gear. - In apparatus comprising positively - actuated auxiliary surfaces which actuate by a current of air or water a main surface such as steering planes of ships or aerial craft, the auxiliary surfaces and the main surface are coupled by gearing or the like so as to have co-ordinated movements. A main rudder a carries two auxiliary surfaces b, c and also connecting-gear. Coaxial with but free on the main rudder is a quadrant d which gears with a quadrant e the spindle of which is coaxial but free on the second surface b and has a second quadrant g, gearing with a pinion h fixed on the spindle of the second surface c. By turning the quadrant d through a definite angle the second surface s is first moved and the action of the current thereon, together with the gearing, results in the main and auxiliary rudders taking up any desired position. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application to the main supporting surfaces of aircraft, and to the vanes of propellers, pumps, fans, ventilators, compressors, and windmills. This subject-matter does not appear in the Specification as accepted.

Abstract: 687,158. Washing granular material. DORR CO. April 5, 1950 [April 20, 1949], No. 8600/50. Class 82(ii) [Also in Group XXX] A classifier comprises a tank with a sloping bottom for holding a bath of suspended solids to be classified and a pair of balanced, parallel, complementally reciprocable structures operating longitudinally of the bath with a rockable longitudinal shaft supporting the rake structures and arms extending from each side of the shaft for operating the rake structures and motivating means for reciprocating the rake structures and rocking the shaft in timed relation. The tank and classifier is of the type described in Specification 613,538, having two rake structures 24, 25 carrying blades 27 above the bottom 11 of the tank 10 into which the liquid-solids suspension is fed through a conduit 9 into the two sections 22, 23 of the tank. Suspended fine solids overflow at the edge 17 whereas large solids pass from the forward upper end 18. An arm 66 of a rake 61 extends along. the tank and supports pairs of arms 63 pivotally connected to the ends of slideways 32. Each member 24, 25 has one or more, upwardly extending members 28 which are connected to a tang 51 extending into the slideways which has two guideways along which move members 41, having shoes 42 in a crosshead with guide blocks 46 to engage a cover 47. The member 28 is reciprocated longitudinally by an arm 124 connected to a pin 55 on the member 28 and connected to one crank of a driving mechanism. A motor drives a shaft 152 driving gears 107, 108 on a shaft 105 in a casing 90 and drives pinions 100, 110 integral with a cam 106. Two cranks 111, 112 are secured to the cam and have arms 123, 124 which engage members 28. The cam 106 has a sinuous, groove 133 in which a roller 134 secured by an arm to the shaft 64 (not shown), moves to impart a rocking motion to the shaft and therefore reciprocate the blades vertically. Should an overload occur the arm rotates disengaging from the shaft 64. The lower end of the shaft can be raised by a piston, Figs. 1 and 23. The tank has side members 86 supporting a shaft 87 having a forwardly projecting part 88 supporting members 89. The piston is mounted on a crosshead 77 and the shaft 67 is mounted in a bearing 71 in eyes at the ends of arms 73 dependent from the crosshead 77. The motor is mounted to allow a pivotal movement as the shaft 67 is elevated at the lower end. In a modification only one pair of gears is used to drive the shaft.

Patent GB-571937-A (GB)
Title: Improvements in or relating to the manufacture of composite or clad metals
IPC: B23K20/04
Filed: 1944-05-09
Abstract: 571,937. Making compound forms. ROBIETTE, A. G. E. May 9, 1944, Nos. 8784 and 10607. [Classes 83 (ii) and 83 (iv)] Welding.-In making composite or clad metals, at least two different metals are subjected to high-frequency induction heating in a non-oxidising atmosphere and are then, before leaving the atmosphere, pressed together to cause them to bond or weld to each other. Steels may thus be faced on one or both surfaces with nickel, copper, copper-nickel alloys or stainless steels, or nickel alloys of low coefficient of expansion such as constantion or the alloy sold under the Registered Trade Mark " Invar " may be bonded to other nickelcopper alloys of higher coefficients of expansion to form bi-metals. The contacting surfaces of one or all of the metals may be previously decarburized, the other surfaces being protected from decarburizing by paints or by electroplating with copper. The steel slab 9 may be machined and then tack or spot-welded to the cladding metal 10 and the assembly placed on a skid 2 and pushed through a high-frequency coil 3 which may be arranged around or within a chamber 1 supplied through an inlet 8 with reducing gas such as cracked ammonia, partly burnt and purified coal gas, or hydrogen. An external chamber may be of high-conductivity non-magnetic metal such as copper or brass, but an internal chamber is of electrically non- conducting material such as a ceramic, fused silica, or asbestos composition. The assembly is welded before it leaves the atmosphere by rollers 7 or by a press which is flooded with reducing gas while pressing is being effected. A cold-rolled mild steel strip 0.1" thick is clad with a stainless steel strip 0.01" thick by heating to 1150‹ C. and rolling in an atmosphere of cracked ammonia. In another form, Fig. 2, a steel strip 21 and a non-ferrous strip 26 such as of copper may be fed through separate induction coils 13, 14 arranged in a non- oxidising chamber 12 of fused silica so as to vary if necessary the energy input to each material, and then led over rolls 18 and between rolls 19, welding being effected by rolls 20. Each coil may alternatively be surrounded by a separate chamber, the chambers merging where the strips come together. The steel strip may first be magnetized by passing between the poles of an electromagnet 22 and then coated by a sprayer 23 with a layer of soft iron powder so as to facilitate diffusion of the metals of the two or more constituent layers. If thefacing metal is also magnetic, such as of nickel, it may also be coated with iron powder. A steel strip may be clad with copper on one side and nickel on the other by providing a third induction coil in the chamber 12. The steel and nickel strips are heated to 1050‹ C. and the copper strip to 900‹ C. Mild steel may be clad with stainless steel on both surfaces in an atmosphere of cracked ammonia or pure hydrogen using a temperature of 1100‹ to 1250‹ C.

Fabric comprising keratinous fibres, e.g. woven and non-woven woollen fabrics, is presensitised for a subsequent setting operation by treating it with an alkaline aqueous solution of an aliphatic amine sulphite and/or bisulphite at a pH of 8-9.5 and then drying it. The subsequent setting which may be effected by the garment manufacturer may comprise flat setting or permanent pleating or creasing. The drying of the fabric may be effected at ambient temperature or slightly above under as little tension as possible and the fabric may then be subjected to dry blowing with steam. The amine sulphite and/or bisulphite which may be present in the solution in a concentration of 2.5-15% by weight may be a sulphite and/or bisulphite of an alkylamide having 1-6 carbon atoms, of an alkyl or alkylene polyamine or of a mono-, di- or trialkanolamine. The solution may be buffered to the desired pH by the addition of an amine. The solution may also contain 0.05-1% by weight of a cationic, anionic or non-ionic wetting agent and 5-12% by weight of a humectant, e.g. urea or ethylene glycol.
