Abstract: 1,253,124. Coating webs. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 20 Feb., 1970 [28 Feb., 1969], No. 10984/69. Heading B2L. [Also in Division D1] A metal sheet 12 is coated with epoxy resin 15 during passage over and spaced from a heated, rotatable roll 10 to which liquid epoxy resin is applied from a coating head 14, the liquid film 41 on the roll vapourising and condensing on the sheet 12. The resin is pumped from a reservoir maintained at 50 to 150C. to a manifold 37 (see also Fig. 3) and then to an adjustable extrusion slit 32 in the head 14, which is heated by electric heaters 35. The roll, which is of high polish, hard chrome, is heated to 150 to 300C by electric heaters 28. A variety of heated baffle plates (52, Figs. 5 to 7) may be placed round the roll to direct the -vapour towards the sheet 12. The apparatus may be enclosed in a chamber evacuated to 0.1 atmospheres. The resin may be transferred from roll 10 to a second roll 10' (Fig. 7) and vapourised from said second roll onto the sheet 12. A doctor blade (9, Fig. 1) may be in contact with the roll. The resin may be subsequently . cured by subjecting it to ionising radiation. The method may be used to coat a web or wire with a non-thermo-setting material.

Abstract: 1,256,517. Drying yarn. WOOL INDUSTRIES RESEARCH ASSOCIATION. 13 Nov., 1969 [15 Nov., 1968], No. 54258/68. Heading F4G.  Apparatus for drying a preformed body of yarn by heating its inner or outer surface while withdrawing yarn therefrom comprises a cylindrical container 5 with lid 7 and a fluid heated hollow inner wall 6. A package is mounted on support 9, and yarn is withdrawn via aperture 12. The amount of heat reaching the package is controlled by rotary heat shield 25, whose walls 28 have apertures of size variable with temperature, and which is rotated by convection currents in the chamber working against vanes 29. Rods 8 and rings 10 control ballooning of the unwinding thread. To mount the package rod 17 is raised by hydraulic ram 19, with the lid off, and the package is placed over the seal 16, the rod then being lowered until the package is seated on the support 9. The heating of the wall may be controlled, the shield 25 being omitted. A plate (not shown) with variable apertures, mounted at the base of the container, may control the air supply. A heated rod mounted within the package may dry yarn being unwound from its inner surface. Part of the support 9 may be connected to the lid, so that both can be raised, the package thus rising clear of the rod 17.

A photo-sensitive sheet 49, e.g. a photoconductive sheet, is developed by feeding the sheet by rollers 416, 417 to one of a plurality of spaces formed on an endless belt 409 and driving the belt through developing liquid contained in a tank 406. The spaces are formed by a large plate 410 and a smaller plate (411), Fig.2 (not shown), the large plate being flexible so that the plate is flexed on contact with the inner wall 406a to hold the photo-sensitive sheet against movement during passage through the developer. The drive of rollers 416, 417 is synchronized with the drive of belt 409. Each plate 410, (411) is apertured to allow developing liquid to pass through, and the plates are dried before reaching the feeding station 406b.

A fastener for fastening a wrist watch strap to a watchcase pin 10 supported between a pair of lugs 12 on a wrist watch case 9, consists of a casing 2 for receiving the watchcase pin 10 and having a cover plate 6 for closing the space bounded by the pin, the watchcase lugs, and the portion of the watchcase periphery situated between the lugs, which plate has a shaped end edge 7 for abutting against such portion, the casing being adapted for attachment of a wrist watch strap thereto at a side 5 of the casing remote from the end edge of the cover plate, and being adapted for receiving the pin longitudinally between said side and an opposite portion 4 of the casing beyond which the cover plate projects, said side and said portion of the casing being spaced apart a distance greater than required for accommodation of the pin diameter between them whereby to render the casing displaceable transversely relative to the pin for adjusting the distance of the end edge of the cover plate from the pin to accord with the distance of the pin from said portion of the watchcase periphery, and the casing housing resilient means 15 arranged to be actuable in use by engagement with the pin for urging the casing in the direction in which to press the end edge of the cover plate against said portion of the watchcase periphery. In the construction shown the casing 2 has a bottom 3 so that in use the pin 10 is enclosed except for its end portions which engage the lugs 12; the resilient means is a leaf spring which has a centre portion which is disposed in a hole in the portion 4 and the end portions of which bear against the pin. The alternative arrangement can however be used if desired. In a modification the bottom 3 can be extended to abut against the peripheral portion 8 of the watch case 9 in which case the leaf spring bears against an abutment turned up from the bottom 3 in place of the portion 4; any suitable form of attachment means can be provided for the strap.

The preferred material is an acrylonitrile homopolymer, and it may be in the form of a yarn. The reducing flame may be obtained by the combustion of acetylene and oxygen. The organic substance may be a mixture incorporating dibenzyl. Organic substances specified include organic compounds of P, Sb or Sn, halogenated alcohols, halogenated esters, halogenated carboxylic acids, the anhydrides of such acids, halogenated phenolic compounds, halogenated aliphatic or aromatic hydrocarbons, or halogenated aromatic ethers.

Abstract: 1301420 Rotary hoe DEERE & CO 18 Oct 1971 [19 Oct 1970] 48371/71 Heading A1B In a tractor mounted rotary hoe having a number of support arms 30 spaced along and rearwardly depending from a transverse tool bar 14, hoe wheels 48, 50 are journalled in the ends of levers 46 pivoted to the rear ends of arms 30 which have spring means, e.g. helical torsion springs 52, acting between the tool bar and the arms 30 to provide a substantially constant downward force at the rear ends of arms 30. In the embodiment the springs 52 are positioned on journal blocks 34 by which the arms 30 are attached to the shafts 32 which are connected to the tool bar 14 by straps 38. Upward displacement of an arm 30 increases the effective lever arm through which its spring 52 acts vertically downwards but since the spring is tightened at the same time the downward force remains substantially constant. Hoe wheels 48, 50 are mounted on opposite sides of levers 46 which are pivoted at a point to the rear of their centres between the forked ends 43 of arms 30. The levers are bent at their pivot point to put that point below the axes of the wheels 48, 50. Stops formed by the front part 44 of arms 30 and by webs 58 between the forked ends 44 limit the downward movement of arms 30 and front wheels 48 respectively when the implement is raised by the three-point lift of the tractor 12.
