Title: Process for modifying the dyeing and other properties of cellulosic textile materials
IPC: D06P1/649
Filed: 1940-12-24
Abstract: 546,122. Treating textiles. COURTAULDS, Ltd., and MACGREGOR, J. H. Dec. 24, 1940, No. 18092. [Classes 2 (iii) and 15 (ii)] The properties of cellulose textile materials, especially their affinity for wool dyes and their softness in handling, are improved by treating them with a solution containing formaldehyde and an arylguanidine or a water-soluble condensate of these components and thereafter, before dyeing, forming a water-insoluble condensate thereof on the materials, e.g. by heating in the presence of an acid catalyst. Among the wool dyes are included acid wool dyes, mordant (including chrome) dyes and those direct cotton dyes which are customarily applied to wool. In Examples, (1) a viscose satin fabric is immersed in an aqueous solution containing sym-diphenylguanidine, formaldehyde and acetic acid, squeezed, dried at just below 100‹C., heated for 15 minutes at 140‹C. and dyed red by treatment for 15 minutes in a boiling aqueous bath containing Azo geranine 2GS and formic acid ; (2) a viscose satin fabric is immersed in an aqueous solution containing triphenylguanidine hydrochloride and formaldehyde, squeezed, dried, heated and dyed as in (1) ; (3) a viscose satin fabric is immersed in an aqueous solution containing a urea-formaldehyde condensate obtained by refluxing urea with aqueous formaldehyde in methanol, diphenylguanidine or a water-soluble condensate thereof with formaldehyde, and acetic acid, squeezed, dried and heated as in (1) and dyed violet by treatment for 20 minutes in a boiling aqueous bath containing Coomassie violet RS and formic acid. Specifications 278,684, [Class 2 (ii)], 301,365, 328,978, [both in Class 15 (ii)], and 450,516 are referred to.

Title: Improvements in or relating to apparatus for treatment of shoe components
Inventor: NEAL FRANK JAMES
IPC: A43D11/14
Filed: 1960-06-24
Abstract: 999,471. Coating apparatus. WELLAND SHOE PRODUCTS Ltd., and F. J. NEAL. Sept. 25, 1961 [June 24, 1960], No. 18222/60. Heading B2B. Apparatus for treatment of shoe stiffeners comprises an endless conveyer carrying at spaced intervals releasable mounting means adapted to hold and grip a stiffener by a flange, the conveyer being so mounted as to dip the major part of such stiffener in a bath of liquid at any part of its travel and to pass through a drying chamber or chambers at another part of its travel, and each of said mounting means having a stiffener holding device which is automatically released at a subsequent discharge station by the conveyer being caused to pass round an arc of short radius. As shown (Fig. 1) the apparatus comprises a framework 10, 11-12 provided at one end at the bottom with a tank or trough 13 extending over the full width of the frame. The framework supports a plurality of endless chains 14 disposed parallel to each other. Above the tank 13 is a sprocket of large radius 15, a similar sprocket of large diameter 16 being disposed near the top of the left-hand end of the frame. Sprockets 17, 18 of small diameter are disposed, 17 at the upper right hand end of the frame and 18 on an adjustable outrigger 30 to control the tension of the chains. The chains are driven by a motor (not shown) driving sprocket 17. Longitudinal members 34 near the top co-operate with side walls 35 to form drying chambers through which the chains pass. The chains are of the type in which alternate links 38, Fig. 5, are narrower than their neighbours 39 and are pivoted between the latter. The wider links 39 carry laterally extending flanges supporting T- brackets 41 provided with central upstanding arms 43 which terminate in gripper jaws 44 parallel to the chain and extending over the adjacent link 38. Link 38 is formed with central lobes 45 supporting pivotally on a transverse pin 46 a hollow block 47 carrying a movable gripper jaw 48. This latter is urged by a spring 51 and a plate 50 both inside the block, against the jaw 44 supported by link 39. As long as the chain moves in a substantially straight path or round a sprocket of large diameter the jaws co-operate, but when it moves round a sprocket of small diameter as in Fig. 7 the pivoting movement causes the jaws to separate. The shoe stiffeners are loaded at A where the jaws are apart, carried down 14a to the tank 13 containing adhesive and taken through the liquid to sprocket 16. They then pass through drying chambers, in the left hand end of which warm air circulates. Hot air is injected at 36, and cooling air at 37. As the holding means pass round sprocket 17, the jaws separate and the stiffener C falls off down an inclined shoot 52.

Abstract: 102,963. Worthington, C. C. Dec. 21, 1915, [Convention date]. Lawn-mowers.-A gang lawn-mower comprises a number of lawn-mower units united by a main framework, the supports of the main framework being so situated that the weight of the framework normally tends to press the cutters against the ground. In the form shown, the lawn-mower comprises three units each of which is provided with a central bearing-post supporting the main frame. The gearing-post 7 of the front unit is attached to a cross-beam 4, which is provided at its ends with guide-posts 9 permitting vertical tilting of the cutter. The cross-beam 4 is connected to the main frame 1 through a fifth-wheel joint 3. The bearing-posts of the rear units are secured to a cross-beam 2, from which a pair of guide-posts 6 for each unit depends. The ends of the bearing-posts are rounded to permit the vertical tilting of the units, and rest upon crossrods 15 extending between the frames of the units behind their main axles 13, but in front of the wiper rolls 14. The position of these crossrods relative to the axles 13 may be varied, either, as shown, by providing a number of sockets for supporting the rods, or by using rods provided with ends bent at right-angles, which can be adjusted in horizontal sockets on the frames. The height of the cutters is adjusted by a lever 24, which is adapted by a link 21, bell-crank levers 19, and chains 18 to turn the mowers about their main axles 13. To allow for the movement cf the fifthwheel joint, the link 21 is formed in two parts connected by a vertical pivot. In a modification, a pair of bearing-posts, one arranged behind and the other before the axle 13, is connected by a rocker lever to which the axle is fixed; the weight of the frame may be transferred from one to the other of the ends of the rocker lever by moving through the lever 24 a corresponding rocking lever pivoted on the main frame and attached to the upper ends of the bearing-posts. Individual cutter-lifting devices may be fitted to each unit. The guide-post 6 may be dispensed with. Specification 16105/14 is referred to.
