Title: Laminated fibrous structure and method of producing such structure
Inventor: KLUG OLUF WALTHER HENRY
IPC: B32B27/00
Filed: 1959-07-29
Abstract: 923,127. Laminates. K. E. S. EKSELIUS. July 29, 1959, No. 26022/59. Class 140. A laminated fibrous structure is produced from three coherent layers of which the inner one consists of an inorganic fibrous material, e.g. a thin mat of randomly oriented fibres or a woven fabric of glass fibre, and the two outer layers consist of vegetable fibres, e.g. felts of jute fibres. The inner layer is coated with a pasty mixture of an unsaturated polyester, e.g. one formed from ethylene glycol and maleic acid, a monomeric unsaturated compound to be copolymerized with the polyester, e.g. styrene, a filler, e.g. colloidal silicic acid, and a polymerization catalyst, so as to completely embed the inorganic fibrous material in the mixture. The layers of vegetable fibres are then coated on one side only with the same mixture. The three layers are brought together with the coated sides of the outer layers facing the inner layer, and the laminated structure is pressed and cured by heating. The product has a fibre-reinforced solid core of synthetic resin with porous layers of vegetable fibres on either side. If the heat for curing is applied from one side only, part of the mixture will have time to migrate, and the product will be more porous on one side than on the other.

Filed: 1970-05-29
Abstract: 1280066 Filters for oil-water separation MITSUI SHIPBUILDING & ENG CO Ltd 29 May 1970 26107/70 Heading B1D An oil-water mixture is separated using a plurality of adjacent oleophillic fibrous filters 6 e.g. of nylon, each fibre being stretched and aligned in the same direction and held between two annular plates, Fig. 2 (not shown). In operation an oil-water mixture is fed in at 1 into a first settling chamber 2, optionally preceded by a coarse meshed wire gauze to prevent large sized solids from passing. Oil is tapped via 10 whilst solids are removed at the bottom. The mixture then enters the filter section 3 whereby the oil particles are deposited upon the fibres. Further oil particles collide and coagulate with those on the fibres and the larger formed droplets then pass on downstream. If solids block up the spaces between the fibres the subsequent rise in pressure causes their removal. Oil particles which float up in a second settling chamber 4 are tapped at 11. Water is withdrawn at 5.

Filed: 1970-06-02
Abstract: 1307413 Knitting machines K TANNERT 2 June 1970 [2 June 1969 19 Aug 1969] 26469/70 Heading D1C In a thread feeder for a knitting machine, a thread store comprising at least one complete convolution is progressively formed on a stationary storage body 2 by means of a revolving guide and progressively shifted along, the thread passing through the body longitudinally in the opposite direction from the feed of the thread store on the body. Within storage body 2 is a hollow shaft 3 connected at one end to drive pulley 4. Thread 101 from supply 100 passes through shaft 3 to eye 52 which winds it on to the edge 21 of body 2 from which it slides down to form the store which moves axially in direction W. When the store reaches position 102a a sensor 71 within body 2 switches off a magnetic switch 6 which is not switched on again until the store has diminished to position 102e. Switch 6 may start and stop or speed up and slow down a drive or may actuate a clutch. The thread is pulled off the store and used in the knitting machine. In a modification, Fig. 2 (not shown), the thread is wound on to a stationary housing by a pair of rotary eyes and is pulled off through the centre of the storage body. In another arrangement, Fig. 4, a cylindrical body 13 is rotated within the stationery body 2 causing the thread store 102 to move. Body 2 may, Figs. 6 and 7, consist of a series of rods 24 each with an end slope 210 within which feed body 13 with ribs 130 rotates about an eccentric axis. A series of feeds at different working stations may have a common drive even if the requirements for thread at different stations are different. As shown, Fig. 9, longitudinally oscillated members connected to discs 131, 132 within a deformable non-rotatable feed body 13 are mounted within rods 24 forming the fixed store. Discs 131, 132 are eccentric and thus body 13 moves radially during rotation of shaft 3. The thread runs in through shaft 3 and is wound on by eye 52. Figures 12 and 13 (not shown) show an arrangement similar to that of Fig. 2 but with positive axial feed for the store. Figure 14 (not shown) shows a tapered storage body in an arrangement similar to Figure 9. Figure 15 (not shown) shows another arrangement similar to Fig. 9 in which the eye 52 is enclosed so as to be suitable for fine threads.
