Title: Method of Fibrillating Synthetic Thermoplastic Film and apparatus therefor
Inventor: SPIVY PAUL LARRY
IPC: D01D5/42
Filed: 1967-07-28
Abstract: 1,190,087. Fibrillating oriented films and fibres. PHILLIPS PETROLEUM CO. 28 July, 1967 [29 July, 1966], No. 34866/67. Heading B5B. [Also in Division D1] A web of film or a filament consisting of an organic synthetic thermoplastic polymeric material and which has been stretched in the longitudinal direction at a stretch ratio sufficiently high to render it fibrillatable is fibrillated by passing it between a pair of co-operating rotating parallel nip rollers which exert a pressure on the film or filament as it passes between them, the direction of travel of the film or filament being parallel to its length, and one of the rollers oscillating along its longitudinal axis or oscillating both rollers along their longitudinal axes in opposite directions. The film may be gathered into a rounded or folded configuration before being passed between the rollers. The frequency of oscillation may be 1000 to 4000 oscillations per minute and the amplitude of oscillation may be 0À1 inch to 6 inches. The rollers may exert a pressure on the film or filament of at least 10 lb. per sq. inch of cross-sectional area of the film or filament. The film or filament may be given two or more passages between the same or different pairs of rollers. The film or filament may be fed between the roller at the rate of 100 to 1000 feet per minute. After passage between the rollers the film or filament may be allowed to relax in an untensioned condition for a period of time sufficient to allow the fibrillated film or filament to crimp spontaneously. The film or filament may consist of a 1-olefin polymer containing polymerised units from one or more C 2 -C 8  monoolefins such as polyethylene or polypropylene. Alternatively, it may consist of a polyamide, a polyester, polyvinyl chloride, polyvinyl alcohol, polyvinyl acetate, polyvinylidene chloride or an acrylic polymer.

Abstract: 1,180,905. Troughing rollers for endless conveyers. MAVOR & COULSON Ltd. 30 July, 1967 [4 Aug., 1966], No. 34957/66. Heading B8A. To permit variation of the troughing angle, the outer ends of roller assemblies 5 are mounted on torsion bars 7. Each bar extends longitudinally of a stringer 1 and has an arm 8 which fits in a roller shaft end-piece 9. An arm 11 at the other end of the bar passes through holes 12 in the stringer I and a slotted bracket 13 supports the bar adjacent the arm 8. The endpieces 9 are angled to reduce any tendency for the conveyer belt (not shown) to move off-centre. Alternatively or in addition, for this purpose, one arm 8 of the opposed pair may be located slightly further along its stringer. The stringers have sockets 3 which fit on to spigots 4 on uprights 2. In a modification, the torsion bars 7 are vertical and their arms 8 are horizontal. Alternatively the arms 8 may have vertical extensions for mounting the end-pieces 9.

Abstract: 800,229. Sewing machines. SINGER MANUFACTURING CO. Nov. 16, 1956 [Dec. 9, 1955], No. 35075/56. Class 112 Stitch forming devices. The needle thread take-up lever 30 comprises a hub 32, journalled on a fulcrum pin 31 secured to the machine head, from one end of which extend the take-up arm 33 and an actuating lever arm 35 which is embraced by a slide block 36 pivotally mounted in a boss on the needle bar driving link 26. The arms 33 and 35 are symmetrical about a vertical reference plane which contains the line X-X joining the thread take-up eyelet 34 with the axis of the fulcrum pin- The bore 40 of the hub, which is of larger diameter than the fulcrum pin, contains a narrow needle bearing 41, symmetrical about the reference plane, in which the "effective bearing width" or length of the line of contact of any needle with the bearing surfaces, is less than half its inside diameter. This allows sufficient movement to accommodate any mis-alignment of parts during the assembly of the machine. The hub is formed at its other end with opposed parallel walls 45 defining a slot perpendicular to the line X-X, and so restricts the movement to rotation about this line and does not affect the path of motion of the eyelet.

The preferred microorganism is Corynebacterium nov. sp. (ATCC 15,570). There may thus be obtained salicylic, 1-hydroxy-2-naphthoic and 2-hydroxy-3-naphthoic acids from naphthlene, phenanthrene and anthracene, respectively.  The hydrocarbons may be halogen or nitro substituted, when the correspondingly substituted hydroxyacids are obtained.

Rollers 15a on the links engage longitudinally-arranged tracks 18 fixed to the sides of the vehicle body, and struts 19 pivotally connect the links intermediate their ends to brackets 12b on the carriage 12. When the vehicle is to be unloaded, the pins 17 are withdrawn permitting the rollers 15a to run forwardly in the tracks 18 so that on tipping the body by hydraulic tipping-gear 20, the member 12 pivots to permit discharge of the contents.

[Class 60.] A machine for sharpening saws including means for grinding the forward edge a of the teeth, Fig. 4, and for bevelling alternate teeth in opposite directions at b, consists of a frame 13 to a part 4 of which the saw 1 is secured by an adjustable arm 3, a sleeve 5 and a boss 7, and a grinding-wheel 8 carried in a bearing 15 at the lower end of a lever 16 pivoted at 17 to an arm 18 pivoted at 20 to the frame. The arm is oscillated, through a screw 24, to raise and lower the wheel 8, by a lever 21 actuated by a cam 22 on a shaft 23, the edges a of the teeth first being ground. The wheel 8 is then set with its axis to one side of the plane of the saw by setting over the lever 16 and locking it in position by a notched arm 25 and a clamping-screw 27, or other locking means, and the bevelled faces b are ground. The saw is fed forward after each tooth is ground by a pawl 41 adjustably mounted by a screw 42a on a lever 40 on a shaft 39, carrying a weighted lever 38 contacting, by means of a screw 37, with a lever 36 actuated by a cam 35 on the shaft 23. When the lever 16 is set over to bevel the teeth the tension of the belt 10 driving the wheel 8 is adjusted by pulleys 29 carried by a rod 32 slidable in a bracket 33 and locked by a screw 34.
