Abstract: 1,235,691. Printeng apparatus. MASCHINENFABRIK WINKLER, FALLERT & CO. A.G. 25 May, 1968 [25 May, 1967], No. 16523/68. Heading B6C. To obtain an even contact pressure between printing cylinder and an impression cylinder in spite of deflection of both during printing, one or other, or both, is made up of a core and a jacket, in contact only in the centre part of the cylinder, and the core, the jacket or both may have end parts with cross-sections differing from their cross-section in the centre part of the cylinder. The core may be tapered at its ends, the jacket may be internally flared, or the core may be tapered and the jacket flared. An increase in applied pressure, e.g. between solid cylinder 14 and a composite cylinder according to the invention, composed of tapered core 12 and flared jacket 11, causes the zone in which core and jacket are in contact to broaden. By use of appropriate core and jacket shapes a uniform contact pressure may be obtained, or the contact pressure may be made lower at the ends of the cylinders, to reduce tearing of web 13.

Abstract: 1,067,114. Continuous casting. SWISS ALUMINIUM Ltd. April 20, 1965 [April 20, 1964], No. 16571/65. Heading B3F. In a wheel type continuous casting machine, Figs. 1 and 2 (not shown) the wheel rim (2), which is cooled, is of channel section having a base and two side flanges (18), Fig. 3 (not shown). The rim co-operates with a cover band (3) to form a mould cavity. The rate of movement of the wheel and the feed of the molten metal into the mould cavity are so correlated that there is always molten metal above the bottom of the wheel rim forming the base of the mould. Molten metal is supplied to the mould cavity from a tundish (5) to the highest point reached by the base of the mould. The tundish has a spout (15) at one end which co-operates with the mould cavity, the level of metal in the tundish being controlled by a float (20) so as to ensure that the molten metal is always above the bottom of the wheel rim. The tundish is pivotable about a rod (14) at the end opposite to the spout and which may be held in contact with the wheel rim by gravity or by fluid means (16). Means are provided for removing impurities from the surface of the metal pool in the tundish before the metal enters the mould cavity. An alternative form of spout is indicated in Fig. 8 (not shown). To ensure that the spout has a good seal with the mould it is formed as an element separate from the tundish and is made of a compressible heat resistant material, e.g. asbestos paper or materials sold under the Trade Marks " MARINITE " or " FIBERFAX ".

Abstract: 1,148,175. Stabilized formaldehyde solutions. FARBENFABRIKEN BAYER A.G. 15 April, 1966 [15 April, 1965], No. 16648/66. Heading C2C. [Also in Division C3] A stabilized aqueous formaldehyde solution is produced by adding, as a stabilizer, a graft polymer of a carboxylic ester of vinyl alcohol grafted on to a polyacetal of formaldehyde and diethylene glycol or triethylene glycol or the product obtained by acid and/or alkaline hydrolysis of such a graft polymer to the formaldehyde solution in an amount of from 0À0001 to 1% by weight, based on the total weight of the solution and heating the resulting composition to a temperature of from 60‹ to 120‹ C. for a period of from 3 to 20 hrs. The preferred graft polymers are obtained by conventional radical polymerization of esters of vinyl alcohol (optionally admixed with monomers capable of free radical polymerization) in the presence of formaldehyde-glycol polyacetals. The hydrolysis of such graft polymers may be effected in a conventional manner using aqueous or alcoholic solutions of organic or inorganic acids such as hydrochloric, sulphuric, perchloric, phosphoric, hydrobromic, toluene sulphonic, chloracetic or formic acids or of bases such as ammonia, amines or alkali or alkaline earth metal hydroxides or alcoholates to give products which may be used directly as stabilizers. When alkali and acid hydrolysis are combined the ester groups of the graft polymer are preferably initially hydrolysed in the alkaline medium and thereafter the acetal groups are hydrolysed in the acid medium.

Title: Improvements in calendering apparatus
Inventor: FOLLISS CHARLES
IPC: D06C15/00
Filed: 1959-05-19
Abstract: 945,544. Coating webs. DUNLOP RUBBER CO. Ltd. May 6, 1960 [May 19, 1959], No. 16888/59. Heading D1L. A calender for applying a layer of rubber to each side of a sheet of fabric comprises a plurality of rolls 2.. 4, a bearing block 9 at each end of each roll, an adjusting screw 15 for each block 9, the screw 15 having a coaxial piston 20 thereon which is slidable in a cylinder 14 and is connected to the block 9, and means for preventing back lash in the screw 15 by applying hydraulic pressure to one side of the piston 20. A portion 21 of the screw 15, which is integral with the piston 20, fits in a recess 12 in the block 9, the cylinder 14 being internally screwthreaded whereby rotation of a worm wheel 22 by a shaft 22a moves the screw 15 and hence the block 9 and roll 4 relatively to the roll 3. A connection 19 allows hydraulic pressure to be applied to the face of the piston 20 nearest the block 9. Heating or cooling fluid may be circulated through an internal, helical groove in the roll 4, see Fig. 2 (not shown). The shaft 22a may be automatically rotated by a control system as described in Specifications 939, 787 and 940, 383. In a modification, the piston 31, which has a head 42 engaging a recess 43 in a block 44 for the roll 3, slides on the screw 30 which makes screw-threaded engagement with a rotatable sleeve 37 integral with a wormwheel 29, a flange 41 on the screw 30 being received in a bore 43a in the block 44 and engaging the head 42. Hydraulic pressure applied at 36 tends to keep the head 42 pressed against the flange 41 so that the piston and block follow the movement of the screw, and provides a hydraulic cushion against which the piston 31 can rise if the roll 3 encounters a projection in the fabric.
