Abstract: 1,129,983. Knitting machines. KLINGER MFG. CO. Ltd. 25 Oct., 1965, No. 45043/65. Heading D1C. An out-turned welt is knitted on a circular machine in a manner similar to that described in specification 1084281 by providing sinkers with an upper 99 and lower 98 loop drawing edge, Figure 7, such that the initial set up courses F, are knitted and drawn over the upper edge 99, Figure 8, and subsequently the sinkers and needles are manipulated to enable the loops on alternate needles to be held on their stems, Figure 10, in the throats 96 of the sinkers whilst all of the needles continue to knit at the upper edge level of the sinkers to produce ,the welt. Simultaneously with the knitting of the welt an air blast is directed downwardly close to the inside of the needle circle where knitting occurs to exert draw off tension on the fabric when knitting takes place. To complete the turned welt the sinkers are withdrawn to permit the needles to draw loops over the lower edge of the sinkers through the last course of 'the welt and the loops held on the stems of The alternate needles so that these latter loops are knitted into the fabric. Knitting is then continued by drawing loops over the lower edge of the sinkers. To enable the sinkers to be withdrawn and inserted to position the loops on the stems of the alternate needles and to enable knitting to be carried out at both upper and lower edge levels of the sinkers, adjustable sinker cams 55, 60, Figure 4, not shown, are provided and are operated as required from the cam drum of the machine. Simultaneously to alter the draw of the needles to correspond to the loop drawing edges of the sinkers the stitch cams 37, 38 Fig. 3, not shown, are vertically adjustably controlled by linkwork from the cam drum. After the production of the set up courses and when the loops have been drawn down by the alternate needles to engage them in the throats 96 of the sinkers a movable central lifting cam 47 raises the alternate needles to ensure that they take yarn into their hooks without knitting it. Subsequently all of the needles take yarn and knit for the completion of the welt.

Apparatus for applying an internal and/or external coating of material to a tubular member comprises means for co-operation with the tubular member to form a reservoir for coating material said means including a pair of deformable diaphragms for sealing against said tubular member. In Fig. 1, a length of hose 10 is sealed with expandible plugs 12 which are also used for suspending the hose in a vertical position between supports 16 and 18. Compressed air is then mtroduced into the hose through valves 14 so as to hold the hose rigid. A reservoir 20 adapted to encircle the hose is threaded on to the hose and is provided with a felt or similarly deformable diaphragm 22 in the region or contact between the reservoir and the hose. The reservoir is then filled with coating material 24 and is then traversed up the hose so that the material 24 is applied evenly over the outer surface thereof. If desired the reservoir may thereafter be moved down the hose to provide another coating and for this purpose a lid 28 having a deformable diaphragm 20 to scrape off a doctor excess material. is applied to the reservoir. The initial coating may be cured or allowed to set and thereafter subsequent coats applied and the coating may be applied along sections of the hose and the hose moved or reversed to complete the coating along its entire length. A blank (not shown) having an outer diameter substantially equal to that of the hose may be provided at one end of the hose so that the reservoir can be slid on to it when the coating or one stage of it is completed. The 'blank with the reservoir thereon can be removed and subsequently applied to another hose to be coated. Fig. 2, (not shown) illustrates a similar device for coating the internal surface of a hose and in this embodiment the hose is supported by rings sewn to the exterior of the hose. In another embodiment (Fig. 3, not shown) a hose is stretched horizontally and an open top reservoir with deformable seals at its ends is traversed along the hose. In such an arrangement about two thirds of the hose surface may be coated during one traverse and the hose rotated 120‹ after each traverse. Any polymer, copolymer or elastomer e.g. polyvinyl chloride, a mixture of polyvinyl chloride and nitriles, or polyurethane. which is capable of being brought into solution, paste or emulsion form and which on drying or curing will form a homogeneous film may be used as coating material.

A temperature sensor 28 controls the addition of fuel through an inlet 24 and a start-up burner 26. Fluidizing gases, which may be the off-gas from a waste or sewage treatment plant, are fed through a distributer 16, and hot refractory particles and incombustible solid residues are cooled in a chamber 18 below the distributer 16 and withdrawn through an inclined passage 19 so that the cooling material provides a seal. A door 30 above the bed is provided to allow replenishment of the bed with refractory particles, and the waste gases from the outlet 34 may be used to preheat the fluidizing gas in a conventional heat exchanger or in a second fluidized bed. In a modification, Fig. 5, the refractory particles are cooled in a fluidized column 113, an inclined passage leading from the bottom of the incinerator bed 111 to the cooling bed 113. Inclined fluidizing gas distributers form part of the floor of this passage, and an outlet 122 is provided for cooled material. The gases from the cooling bed 113 are mixed with those from the incinerator bed to facilitate particle removal. The size of the distributers and unfluidized depth of the beds is arranged so that, with the material outlet closed, sufficient gas is supplied through the two distributers to fluidize both beds. In operation, the incinerator bed rises to a greater height than the cooling bed to allow the flow of material to the cooler. Gases withdrawn from the material outlet 122 are returned to cool observation devices or to prevent issue of hot gases or back-firing in the waste supply duct, which is preferably sloped upwardly to the bed inlet.
