Abstract: 1,049,521. Laminates and laminating. WESTON-EVANS & CO. Ltd. Feb. 13, 1963 [Feb. 17, 1962], No. 6232/62. Heading B5N. In apparatus for laminating a knitted, non-woven or other textile web to another web, which may be of textile or foam material, the textile web is fed from a pile 8 or a roll (not shown) by a pair of stenter chains 1 which are mounted on frames 4 which are hinged about an axis 4a. The delivery ends of the stenter chains are fixed in relation to the laminating means and the entrance ends are movable about hinge 4a by a control means and a selvedge sensing device so that the entrance ends of the chains will be kept in line with the selvedge. The stenter chains have pins or clips and the fabric web is fed on to the pins by over-feed devices (one for each chain) which are adjustable to provide up to 15% over-feed. The web is stripped from the stenter chains by stripping roll 25, passes over guide roll 24 and over the combining roll 26. The fabric web is coated by adhesive by an endless band 20 on which has been spread adhesive 22 by a doctor blade. The second web e.g. a thin foam web is taken from a roll 28 and is combined with the fabric web by the rollers 24, 26. The laminate then passes round a heated drum 31 and is pressed against the drum by an endless conveyer band 35 and is finally wound up on a roll 34. In a second embodiment (not shown) the fabric web is coated by adhesive by the device described in Specification 1,049,522. In a third embodiment (not shown) the foam web is made tacky by flame treatment.

Two idler roller assemblies constitute a troughed idler roller set, each assembly comprising two rollers 1, 2 cantilevered from and supported by a common bracket 7. This bracket is pivotally mounted on a bracket member 21 secured to a base plate 20 and has a leg 11 which extends into the bracket member 21 to bear against a resilient pad 23. The bracket member 21 is inclined, Fig. 2, to improve tracking and centralization of the belt. When the conveyer belt is not loaded the idlers 1 are horizontal, Fig. 4a (not shown). Upon loading, the idler assemblies pivot such that these bracket legs 11 compress the pads 23, the idlers 1 being inclined towards one another and the wing idlers 2 becoming more steeply inclined to the vertical, Fig. 4b (not shown). A supporting framework comprises stringer tubes 30 supported by stools 31 each consisting of a pair of spaced legs 32 bridged by an L-section cross-piece 33 welded to the legs. Welded to the cross-piece are two U-shaped brackets 34 into which the stringer tubes are dropped and fixed by spring pins 35. The base plate 20 of each idler set is replaced by a pair of inverted U-shaped brackets 39 welded to either end of a cross-tube 40. The brackets 39 seat on the stringer tubes and are secured by pins 41. Feet 42 may be made vertically adjustable.

Title: Processes for preparing catalytic gels
IPC: B01J37/02
Filed: 1928-03-02
Abstract: 286,309. Silica Gel Corporation, (Assignees of Latshaw, M., and Judefind, IV. L.). March 3, 1927, [Convention date]. Catalytic agents.-Highly porous gels such as silica, stannic oxides, tungstic oxide, aluminium oxide &c. are impregnated with a catalytic metal or compound thereof by charging the gel with a gaseous compound having a reducing action and then treating it with a solution of a compound of the catalytic metal. The metal may be, for example, platinum, silver, nickel, copper, palladium, iron; the reducing gas may be sulphur dioxide, carbon monoxide, or hydrogen sulphide. The two former gases precipitate the metal itself; hydrogen sulphide usually precipitates the sulphide which may be converted by known methods in the metal or compound such as the oxide. Before being charged with the reducing gas the gel is preferably heated in vacuo to empty the pores. Absorption of the gas may be increased by cooling below normal temperature. The process is applicable to gels which have been prepared by precipitation with any acid, including sulphuric acid.
