Title: Method of manufacturing gelled polyvinyl chloride sheets or plates
IPC: B29C48/07
Filed: 1964-12-17
Abstract: 1,095,705. Sheeting P.V.C. SOMMER S.A. Dec. 17, 1964 [Dec. 18, 1963], No. 51336/64. Heading B5A. In the manufacture of gelled plastic sheets or plates, an unsupported layer of uncured polyvinyl chloride plastisol paste is deposited by means of a feeding device on to a rotary internally heated roll on which the layer is gelled while it is at its final dimensions. As illustrated in Fig. 1, the feeding device comprises a doctor 1 which spreads uncured plastisol paste 5 on to rotary roll 3 at peripheral position A to form a layer 4 which, after gelling, is removed from the roll at peripheral position B by auxiliary roll 9 to give sheet 10. To prevent pregelling of the plastisol paste, the doctor may be cooled, for example by circulation of cold water through cavity 2 formed therein. As illustrated in Fig. 2 (not shown), the feeding device comprises a single roll, whch may be internally cooled, acting as a rotary doctor; as illustrated in Fig. 3, the feeding device comprises two rolls 7 and 8, each of which may be internally cooled, rotating in opposite directions and together acting as a calender. The rotary internally heated roll preferably is heated to a temperature between 160 and 197 C., for example by means described in Specification 1,026,753. The layer may pass over at least one further rotary internally heated roll disposed after the rotary internally heated roll receiving the uncured plastisol layer; as illustrated in Fig. 4 (not shown), the layer passes around and in contact with a major portion of the periphery of each of a receiving roll and two further rolls before being removed by an auxiliary roll. The sheet or plate may be either formed, for example, with a hollow pattern, drawing or ornamental design, which subsequently is filled by an additional coating, or lined with a bedizened polyvinyl chloride sheet or film which is to constitute the wearing layer of the article when used as a lining.

Abstract: 1394263 Threading false twist crimping machines BARMAG BARMER MACHINENFABRIK AG 9 Nov 1972 [9 Nov 1971] 51691/72 Heading DIF In a method of drawing and false-twist crimping thermoplastic filaments in which undrawn thermoplastic filaments are continuously subjected to drawing and false-twist crimping and which heating is by means of a contactheater plate 2, during threading-up of the filament 1, the filament is diverted from the path it follows during normal operation between delivery rollers 5 upstream of the heater 2 and take-off rollers 12 downstream of the heater, so as not to make contact with the heater until a draw as been applied to the travelling filament, the length of the filament path between the rollers 5 and 12 remaining substantially constant, the working rotational speed of the false-twist spindle 11 not being adjusted to its functional level until after the filament has been brought into contact with the heater 2. In a first embodiment of apparatus for carrying out the above method, the delivery rollers 5 are moved along a path 7 between two end positions 8 and 9 in which the filament 1 does and does not make contact, respectively, with the heater plate 2. The path 7 is such that the length of the filament path between the delivery rollers 5 and the take-off roller 12 does not change. The delivery rollers 5 and take-off rollers 12 are connected via a gear transmission 27 to produce the desired draw ratio in the filament. In a further embodiment, in which the filament passes a plurality of times across the heater surface via direction changing guides, said guides are displaceable towards and away from the heater surface to bring the filament into positions in which it does and does not make contact with said surface.

Filed: 1965-12-07
Abstract: 1,121,668. Etching. KERAMISCHE WERKE HERMSDORF VEB. 7 Dec., 1965, No. 51861/65. Heading B6J. [Also in Division H1] An etch-resistant mask is produced on a substrate by subjecting a substrate-masking layer of nitrocellulose lacquer to the action of an electron beam at regions of the layer which are not required to exert a masking action on the substrate, and treating the exposed regions with a chemical reagent e.g. ferric chloride or ammonium peroxydisulphate, to remove the lacquer selectively at the said regions. The electron beam charge density is between 5 and 10 microamp seconds per square millimetre. The exposure may be made through an electron-permeable stencil by direct masking or electron-optical image projection therethrough. Alternatively an electron probe may be guided over the layer by a programme controlled deflection system. The substrate may be a copper layer on a glass base, the abovementioned reagents attacking the copper after selective removal of the lacquer.

A tempered glass sheet for use as a windscreen is characterized by a fragmentation system comprising in a central zone C successive strips 6 with fine fragmentation characteristics alternating with strips 4 with larger fragmentation characteristics (the strips preferably being parallel and vertical, and the width of the larger fragment strips preferably corresponding to the mean large fragment diameter) and by a marginal zone M 1 , M 2  in which the size of fragments 7a, 7b, 7c increases from the sheet edge towards the central zone. The sheet is obtained by differential cooling of the centre zone to give strips of glass which are lowtempered and high-tempered respectively and by differential tempering of the marginal zone, the degree of tempering diminishing from sheet edge to centre zone. Apparatus for producing the sheet may comprise two chests 9 and 10, fed with cooling fluid under pressure from ducts 11, each main chest containing a smaller chest 18 and 19 whose periphery corresponds to that of the central zone of the glass, and each small chest having nozzles 20 so arranged that blasts of cooling fluid fall in lines corresponding to fine fragmentation strips 6 (large fragment strips 4 remaining untempered), the remaining blowing surfaces 14 and 15 of the chests 9 and 10 having perforations 25, either of diameters which decrease towards the small chest or whose spacing increases towards the centre, so that the degree of tempering decreases, and the fragment size increases, from edge to centre.

Relates to a thermal regenerator having an annular, rotatable, radial-flow matrix 21 which moves through heating and heated fluid zones 26, 25 of a stationary casing 19 separated from each other by a bulkhead 23 through which the matrix is arranged to pass by way of a main seal co-operating with the matrix at the bulkhead. The invention comprises improvements to the main seal wherein the main seal housing 54 includes a first seal bar 56 extending across the hotter face of the matrix, a second seal bar 55 extending across the cooler face of the matrix and two side plates 58 rigidly fixed to and interconnecting the seal bars being adapted to flex in order to accommodate relative thermal expansion of the lengths of the seal bars when the regenerator is operating; and rollers 37, 83 being mounted in the housing 54 to engage the matrix faces. The seal bars 55, 56 coact directly with the matrix and additionally in the seal bar 55 on the cooler side of the matrix a further rubbing seal comprising a removable strip 114 of a hard material such as cemented carbide is provided. Rollers 37 rotate on bearings 95 and 102 mounted in recesses at the ends of the seal bar 55 and are oil cooled and lubricated. Hence the side plates 58 which are secured (bolts 60, Fig. 8) to the seal bar 55 provide the support for the rollers 37. In the seal bar 56 at the hotter face of the matrix, the rollers 83 are mounted on a shaft 75 carried in bearings 76 disposed outboard of the rollers, with heat insulating material 90, 92 covering the shaft and a substantial part of each roller. The shaft is hollow and is cooled by the oil which also lubricates the bearings. The bearings 76 are mounted in bosses 44, 48 in end plates 43, 47 of a seal frame 42 in which the seal housing is mounted with slight freedom for tilting about pivots (62, Figs. 4 and 8).
