Title: Method of manufacturing friction parts from asbestos-polymer mixture
Inventor: NIKANOROV VILORIJ VIKTOROVICH
IPC: C08J5/14
Filed: 1992-05-07
Granted: 1997-08-20
Abstract: FIELD: FRICTION PARTS. SUBSTANCE: scope of invention covers manufacturing brake blocks and brake pads for rail-way and automobile transport, tractors, load-lifting and other mechanisms. Friction parts are manufactured from asbestos-polymer mixture containing fibrous asbestos, polymer binder, fillers, and desired components. Method consists in pressing asbestos-polymer mixture heated to softening temperature of polymer binder in press-mold to achieve hardness constituting 30-35% of desired hardness of final friction object. Subsequent heat treatment in kiln is carried out at rising temperature: from softening temperature to hardening temperature of polymer binder for 3-8 h to yield friction products with required physico-mechanical characteristics. Press-mold is heated to a temperature ranged from 60 to 120 C depending of softening temperature of polymer binder. Pressing time is 10 s per 100 g of asbestos-polymer mass being pressed. Pressure in this procedure is 60 MPa when Brinell hardness is 15. Heat treatment in kiln is carried out at temperature from 60-120 to 170 or 220 C depending on polymer binder type, resin or rubber, respectively. When compounded polymer binder is used including rubber and phenolformaldehyde resin, temperature is chosen according to highest softening temperature of binder components. EFFECT: widened assortment of manufactured friction parts and reduced power consumption. 3 cl, 1 tbl

Patent DE-19739540-C1 (DE)
Title: Warp knit production
Inventor: FISCHER JOACHIM
IPC: D04B21/06
Filed: 1997-09-09
Granted: 1999-03-04
Abstract: To produce a warp knitted fabric, at least one pattern yarn is passed behind a band of ground yarns where there is a gap. The gripper can pass through the gap to grip the pattern yarn. In an Independent claim a warp knitter has at least one ground guide bar (14,15) between a pattern guide bar (16,17) and the selection system (23). Two neighbouring ground yarn guide needles (9) are near each grip (24), to form a free needle passage in succession or tightly against each other.Preferred Features: The gap in the ground yarn band is formed only temporarily during a working cycle. The gap is formed by one guide needle, in a pair, moving behind the other to form a passage or by one guide needle moving closer to the other. Where the pattern yarn guide needles are each in a one-quarter machine fineness in two displaced rows, the pattern yarn guide needles are in an intermediate zone in the leading offset row and one pattern yarn guide needle in the trailing offset row is aligned with the gap in the band of ground yarns. The pattern yarns are held out of the knitting action, so that the pattern yarn guide needles are forced against the displacement movement of the pattern guide bar. The pattern yarn caught by the grip at one wale, is bonded again at the zone of another wale. Before the pattern yarn is cut, it is passed over at least two knitting needles. Two ground guide bars (14,15) are used, with their guide needles (9) fixed at half the machine fineness, and augmented against each other. A control for the displacement gives an additional deflection to the ground guide bar movement on a normal displacement movement. Two rows of ground yarn guide needles can each be at half the machine fineness, augmented against each other so that in one row they are fixed, and the other row are displacement needles which are moved to form the passage in the ground yarns. Or the guide bars carry fixed and displacement needles alternately, for additional displacement movements under control. The pattern yarn guide needles can have a deflection movement to the adjacent fixed ground yarn guide needle. The deflection movement is through an underlying offset motion. The pattern guide bars (16,17) have guide needles (11,12) each at one-quarter of the machine fineness, which can be displaced separately by one or two needle intervals.
