Title: Improvements in or relating to boxes
Inventor: KAMPER ANDREW MATHIS
IPC: B65D6/24
Filed: 1960-09-21
Abstract: 920,460. Improvements in boxes. NO-NAIL BOXES Ltd. Sept 21, 1961 [Sept. 21, 1960; Nov. 8, 1960], Nos. 32385/60 and 38404/60. Class 18. A set of parts which can be set up to form a box consists of two separate panels 26, 27 and a blank comprising three or four panels arranged in a line and hinged or flexibly secured together by means of flanged metal binding strip attached along the two sides of the row to the panel margins. The blank can be folded to form a bottom box panel 20, two opposite side panels 21, 22, and a lid 23 is provided by the fourth panel. The strip has a main strip part 24 which lies flat against the outer surface of the blank when in box form and flanges 24<SP>1</SP> cranked round the edge surfaces of the panels and spaced therefrom to form channels. The flanges have re-entrant lips 24<SP>11</SP> partially closing the channels for engaging marginal portions of the separate panels, or elements secured thereto or both, so as to interlock the said separate panels and at least two panels included in the blank which are to constitute two opposite walls of the box. In one form of the invention the separate panels have battens 28 stapled to the outsides of the vertical margins which are slidably engaged along their inner edges 28<SP>1</SP> by the re-entrant lips 24<SP>11</SP>. The separate panels are slid into position and a box as shown in Fig. 1 is thus set up. Lugs 31, 32 are passed through slots 33, 34 and are bent outward and downward to secure the lid. The battens may be replaced by metal strips of U-shaped cross-section, one arm of the U being engaged by the lip 24<SP>11</SP> when the box is set up. Alternatively the lip may engage a groove replacing the batten. Alternatively to secure the lid the separate panels may be fitted with metal strips of pot hook shape (see Fig. 8) fitting closely round the top and bottom edges of the panel, the longer limbs 41, 42 being rivetted to the inner sides of the panel and the limbs 43, 44, projecting toward one another outwardly with respect to the outer surface of the panel. When the end panel is slid into position the limb 44 snaps past and engages under the lip on the strip engaged to the bottom panel. Similarly when the lid is closed the lip on the strip secured thereto snaps under and engages beneath limb 43. The metal strips and the metal strips replacing the battens may be combined in a single embodiment Fig. 10. The margins of the separate panels which are lowermost in the assembled box are rebated to clear the inturned lips on the flanges of the strip parts attached to the bottom panel and similarly the upper margins are rebated if the box has a hinged lid. If the separate panels are of wood they are arranged such that the grain extends approximately vertically in the assembled box.

Title: Method of treatment of wool scouring or other liquors containing grease and soap or the like for the recovery and if required for the purification of technically-valuable products therefrom and the re-use of the liquors
IPC: C11B11/00
Filed: 1937-11-29
Abstract: 508,371. Treating wool washing liquors. JONES, G., and McGREGOR & SONS, Ltd., J. W. Nov. 29, 1937, No. 32949. Drawings to Specification. [Class 91] Wool-washing liquor is freed from soap and grease by adding the oxide, hydroxide, or the normal or basic salt of a metal which (a) forms water-insoluble soaps, (b) forms insoluble normal or basic salts with a polybasic acid, (c) forms water-soluble acid salts with a polybasic acid, then treating the mixture with a polybasic acid in sufficient amount to form the corresponding acid salt of the added oxide and of the alkali carbonates present in the liquor, whereupon the soaps and grease are precipitated and separated. Alternatively, the acid salt is added directly. For example, the liquor is treated with chalk or milk of lime, and then carbon dioxide or dust-free flue gas is blown in, while keeping the temperature low. Precipitation is assisted by adding fuller's earth, bentonite, aluminium sulphate, magnesium or calcium chloride or sulphate, or ferrous sulphate. The liquor is then filtered warm, and the filtrate freed from calcium bicarbonate by boiling, blowing in air at 160‹ F., or addition of caustic alkali; the precipitate is removed by filtration, leaving the regenerated liquor. The moist soap and grease obtained at the first separation stage is worked up (1) by extracting with boiling benzene or toluene which removes the grease and water ; (2) the soap residue is rejected or used as precipitating agent at the first stage, and the grease containing some soaps purified by neutralizing and extracting with acetone and ethyl or methyl acetate, if desired in the presence of an adsorbent ; (3) by treating the soap residue to form fatty acids which may be connected into alkali soaps, and used for wool scouring.
