Title: Coated non woven materials
IPC: D04H1/488
Filed: 1965-12-29
Abstract: 1,132,349. Coated nonwoven materials. CARL FREUDENBERG. 29 Dec., 1965 [31 Dec., 1964], No. 55073/65. Heading B2E. A water absorbent and abrasion resistant chamois leather substitute is produced by bonding a water absorbent nonwoven material, before during or after bonding impregnating the material with an aqueous solution of water-soluble compound drying the material and then reducing the tendency of the surfaces of the material to fill by forming on both surfaces a porous binder layer by applying to them a coagulatable rubber latex and then coagulating the latex and vulcanizing the rubber and leaching the water soluble compound out of the material. The non-woven material may be bonded mechanically by needling or by impregnation with the binding agent, impregnation with the water soluble compound may be effected simultaneously with the binding agent. The binding agent may be applied by impregnating the nonwoven material with a dispersion of the binding agent in one or more impregnating operations and in which this dispersion in at least the final impregnating operation, or in the only impregnating operation if there is only one, contains a thickening agent. The coagulatable rubber latex may be applied in the form of a foam and may be a heat sensitive coagulatable latex and coagulation is caused by heating the impregnated material. In order for the latex to be heat sensitive, the latex includes a coagulant selected from polyvinyl methyl ether, polyoxypropylene glycol or a siloxane compound, the solubility of which in water decreases as the temperature of the water increases. Suitable rubber latex may be that of butadiene-acrylonitrile or - styrene copolymers. Specified non woven materials are fleeces of cotton, regenerated cellulose, and a mixture of cotton and ramie. The water soluble compound may be Glauber's Salt and/or urea.

Abstract: 1,180,458. Machinery safety devices. ETABS. GUILLIET. 5 Dec., 1967 [6 Dec., 1966], No. 55276/67. Heading F2J. Relates to protection and control circuits for a log saw comprising a log-carrying carriage 18 movable on rails 19 in front of a band saw blade 4 and carrying headstocks 21 movable transversely of the direction of movement of the carriage, each headstock carrying at least one clamp 25, 26 adjustable in height, the frame 1 of the saw carrying a guard 8 slidable parallel to the blade 4 between an upper position exposing the blade for sawing and a lower, safe position. When all the clamps 26 are moved to their fully lowered rest positions 26a and the headstocks 21 are moved to a rest position 21a withdrawn from the saw blade 4, they actuate respective limit switches G 1 , G 2 , G 3 , K to energize a relay DP to supply power to an electric motor P to lower the guard 8 to its safe position. The guard 8 is mounted on a slide 7 movable between vertical guides 6 on the frame 1, and is drivingly connected to the motor P by a chain 11. A relay MP controls energization of the motor P to raise the guard 8. At its upper and lower limits of movement, the guard actuates respective limit switches R, Q to stop the motor P. The headstocks 21 are traversed by a leadscrew 23 driven by a motor M controlled by relays VM, RM. The carriage is moved by a motor A controlled by relays VA, RA. With the carriage in a predetermined rest position, a limit switch N is actuated to energize relay DP to lower the guard 8 if it is not already in the safe position. Manual push-button switches cmp, cdp also control the raising and lowering, respectively, of the guard, and a contact op controlled by a sensing device O which senses any obstacle in the path of the guard ensures complete raising of the guard before a log reaches the blade. Push-button switches cvm and D are closed to advance the headstocks towards the saw blade, and crm to withdraw the headstocks. Push-button switches cva, cra are effective to control movement of the carriage by the motor A only when the guard is in the raised position (ga closed) or all the clamps 26 are in their rest positions 26a. When the clamps 26 are in their rest positions, contacts gm 1 , gm 2 , gm 3  are closed to automatically move the headstocks to their rest position 21a.

Another mould release agent may be present in addition to the zinc compound. The epoxy resin may be a diglycidyl ether of bisphenol A or of a novolac. The composition may be prepared by mixing together the epoxy resin, the curing agent and the organo-zinc compound and heating the mixture (e.g. at 200‹ F.) to prepolymerize the resin substantially short of complete cure; the mixture is cooled and ground to particles of the required size. The composition is shelf stable at room temperature but rapidly cures on heating, e.g. 300‹ F. for 5 minutes.
