Abstract: 1325409 Clothes airers HILLS INDUSTRIES Ltd 15 March 1972 [18 March 1971] 11945/72 Heading A4U In a clothes airer comprising radial support arms 29 pivoted to a boss 25, which slides on a standard 11, and supported by pivoted links 14, which are pivoted at their upper ends to the standard, clothes lines 35 are secured to and extend between the arms which are maintained in an extended position by the engagement, at a position higher than at least some of the clothes lines, of a latch member 19 with a lug 31 on the boss. The member 19 is freely pivoted on a collar 18 secured to the standard and has an outwardly extending portion which provides a finger grip and a cam face. The arms 29 comprise an upper member 33 and a lower member 34 to which the lines 35 are secured, tension in the lines increasing as the boss is moved upwardly and decreasing after the boss has passed into an overcentre position, so that the airer is stable even if the latch does not operate properly. A second lower latch may be provided to secure the arms in folded position. In a modification shown in Fig.2, the arms each comprise a single member having line-securing loops on its upper surface.

Title: Anodizing Process
Inventor: DARROW GEORGE RICHARD
IPC: C25D11/14
Filed: 1967-03-14
Abstract: 1,179,422. Ornamenting. REYNOLDS METALS CO. 14 March, 1967 [17 March, 1966], No. 11982/67. Heading B6G. [Also in Division C7] Decorative patterns are produced on an anodizable metal surface, such as sheet or extruded aluminium metal or alloy, by anodizing the surface to produce a first anodic coat thereon, applying a resist layer to selected areas of the first coat, anodizing areas unprotected by the resist layer to produce thereon a second anodic coat while leaving the resist layer in place, thoroughly sealing the coats and then removing the resist to expose the entire pattern. The resist material, e.g. a vinyl fluoride-vinyl acetate copolymer dissolved in ketone with silicone resin, may be applied by silk screening, stenciling, or masking and spraying. The first anodic coat may be partially sealed before applying the resist and the coat removed from the unprotected areas, e.g. by caustic etching, to expose metal on which the second anodic coat is formed of different appearance, e.g. a darker colour from the first. Before final removal of the resist, a further resist layer may be applied to selected areas and the areas unprotected by such resist layer anodized to form a further anodic coat thereon of different appearance, e.g. again a darker colour from the first and second coats, the steps being repeated with or without sealing and etching until the desired number of coats is attained. Where the anodic coating has been rinsed and dried without sealing, removal of coating is unnecessary. A 3-D gold-bronze-black design may be produced on Al sheet by successive anodizing in an aqueous bath containing 5-20% H 2 SO 4 , or sulphosalicylic or sulphophthalic acid with H 2 SO 4 . For multicolour anodizing, an electrolyte containing 0À05-4À5% H 2 SO 4 , 0À5-9% oxalic acid and 0À5-8% ferric oxalate may be used, the voltage being raised during each anodizing step; the current density may vary from 10 to 60 ASF. The final removal of the resist may be effected by a suitable organic solvent, e.g. methyl-isobutyl or ethyl ketone, or isophorone. Partial sealing may be effected in distilled or deionized water at 205-212 F. for 3 minutes. The Al surface may be prepared for anodizing by degreasing in an alkaline bath, rinsing, caustic etched and desmutled in dilute nitric acid.

Abstract: 1,222,505. Casting composite articles; making dies. PRESS & SHEAR MACHINERY CO. Ltd. 13 March, 1968 [15 March, 1967], No. 12065/67. Headings B3A and B3F. Matched press tools or dies for forming sheet material are made by lowering a perforated master pattern 30 mounted on a clamping plate 28 and on a vertically movable beam into a heated tank of molten low melting point (e.g. 70‹ C.) alloy 11, allowing the molten alloy to permeate through the perforations in the master pattern, and cooling the alloy by passing water from a cooler 17 over its surface. During solidification air pressure is applied at 16 to force the molten alloy from closed parts 15 into the centre of tank 11 and so prevent the formation of cavities in the casting. Preferably anchor bars 27, mounted on spacers 26 and thereby attached to the vertically movable beam are lowered with the master pattern. The molten alloy which may be melted in the tank solidifies around the anchor bars 27, to form a support for the male part of the die. After solidification ram sub-plate 25 is detached from the rest of the beam and the die assembly is mounted in a press. The die parts are separated by opening the press; the master pattern adhering to the male part of the die, from which it is subsequently removed, and the tank forming the female part of the die. The small asperities formed where the perforations of the master pattern are cleaned off. In further embodiments blank sheet holders may be formed with the dies and the whole die manufacturing procedure may take place in the press in which the dies are to be used.

Superheating by a throttling.-In a high-pressure steam power installation in which the steam, generated above the critical pressure, is throttled down to working pressure and superheated, the throttling is effected mainly in the superheater 4 instead of by means of the usual throttle valve 3. For this purpose the dimensions of the superheater are such that surplus pressure is consumed by the resistance to flow. The steam then passes through a turbine 6, and condenser 8 and the water is returned to the generator 2.

A copy-milling machine comprises a worktable 38 longitudinally slidable on a support 20 adjustable vertically on a main pedestal 12, a cross-head 16 supported at its ends on the main pedestal and an auxiliary pedestal 14, and a spindle-head 30 slidable across the head and carrying a vertical milling-spindle 54, there being a pattern-carrying table 46 located outside the auxiliary pedestal and alongside the work-table, the tables being movable together longitudinally and vertically. A hand lever 26 operates clamps to secure the support 20 to the pedestal 12 and to the pedestal 14 by way of the T-slot 24 therein. The head 16 has ways 28 to support the gear-box 30 and ways 32 to support a slide 34. The ways 28 are separated by a recess to accommodate an hydraulic cylinder to move the gear-box 30. The support 20 is adjusted by a screw or an hydraulic cylinder 36. The table 38 moves on inclined guides 40 and carries a support 42 carrying a slide 44 surmounted by a compound table 48, 50 and the pattern table 46. A control panel 51 is mounted on the support 42. A spindle 70, for a milling-cutter for finishing, is rotated by cased belt gearing 72 and is mounted in a casing 68 bolted to the spindle head 52 adjustable vertically on the box 30 by an hydraulic device 62. The spindle head contains the rough-cutting spindle 54 rotated by a motor 56 at a speed adjusted by controls 58, 60. An hydraulic control device 76 can be mounted on the casing 68 or on a storage bracket 64 on the box 30 when the finishing is to be under manual control. The device 76 includes a tracer 116, Fig. 7, engaged in a conically-recessed stub 112 on a slide 86. A tracer head 90 is mounted on a slide 88 which can be clamped by a screw 92 to the slide 86 movable on a beam 82 which is adjustable vertically on the slide 34 and is balanced by a spring 106. A pantograph 98 is tiltable about a pivot 104 and is connected to the beam 82 by a bracket 96. The slide 86 can thus be moved by the pantograph in three co-ordinate directions. In operation, with the casing 68 locked to the head 52, the tracer 90 can be guided over the pattern by the handle 100 on the pantograph so that the feeler 116 is caused to control vertical movement of the spindle head, horizontal movement of the box 30 and horizontal movement of the table 38. The combined movements of work and tool thus cause the pattern to be reproduced. It it is desired to cut in consecutive strokes, the slide 34 is looked by a lever 108, the table 38 then being fed incrementally. For finishing, the control element 76 is placed in the bracket 64, the slide 86 is locked to the casing 68 and the casing is detached from the box 30 which is moved out-ofthe-way to the left. The machine may be electrically controlled.
