Abstract: 1354564 Polytetramethylene terephthalate yarns FIBER INDUSTRIES Inc 22 June 1971 [22 June 1970] 29177/71 Heading B5B Yarns are prepared from a copolymer or polymer mixture consisting of at least 85% by weight of poly(tetramethylene) terephthalate having an intrinsic viscosity (as herein defined) of between 10 and 50. The polymer is melt-spun into between 5 and 70 filaments at a temperature between 240‹ and 280‹ C., the yarn wound up at a rate between 1000 and 10,000 feet per minute and then stretched to a ratio of between 1À0 and 5À0 at a temperature of between 60‹ and 180‹ C. During the extrusion step the thread-line tension is at least 0À09 gm. on each filament. It is also essential that the total spinning thread-line tension is equal to or greater than a number derived from the total spun denier of the yarn, the relative viscosity of the polymer, the spinning temperature, the number of filaments extruded and the windup speed. The stretching step may be performed in one or in two stages, the choice being by the result of a calculation involving the windup speed, the spinning temperature, the temperature of the feed roll in the drawing stage, the relative viscosity of the polymer and the number of filaments extruded. If a two-stage process is used the first stage is a cold one, stretching the yarn at a draw ratio of between 1À0 and 1À6.

IPC: F16B12/40
Filed: 1967-06-24
Abstract: 1,191,134. Tube couplings. SQUARE TUBE SYSTEMS Ltd. 24 June, 1968 [24 June, 1967], No. 29251/67. Heading F2G. [Also in Division E2] A joint between two or more tubular members T is formed by first assembling together two or more of a number of standard elements A, B, C, D of which A is merely a cap element, B is a body element with only one arm, C is a body element with two coplanar arms, and D is either a separate arm element, as shown, or may be an element with two coplanar arms and one transverse arm, i.e. equivalent to C and D integrated, thus securing the tubular members T to the arms by internal clamp assemblies comprising intermediate expansible sleeves 24 which have internal wedge surfaces 30, 31 (Fig. 3) co-operating with inner and outer portions 20 (b, c or d) and 19 (b, c or d), respectively. In each case, the sleeve is drawn over the arm by means of a screw 36 and a metal plate 37, which has a threaded aperture 38 to receive the screw and tongues 40 adapted to bite into the walls of the tubular member. The expansible sleeves are of plastic material, slit from either end as shown to provide for expansion by engagement with the portions 19, 20, and provided with a tongue 26 engageable with a groove 21 (b, c or d) in the respective arm. In assembling the clamping elements, each sleeve 24 is first pushed on to the relevant arm as far as it will go without expansion, the screw and plate is loosely assembled, and this assembly is then pushed into the tubular member until a flange 25 on the sleeve engages the end of the tubular member, the screw 36 then being tightened against a shoulder 22 (b or c). The purpose of the separate cap element A and its associated screw 41 is primarily to hide the heads of the screws 36 but it also enables the separate transverse arm D to be secured in place by the screw 41, lugs 23 on the arm D entering notches 18b provided in a recess 17b in the body part 11 (b or c). Element A may, however, be replaced by an element B or C, and screw 41 may be replaced by a long stud to allow two elements D to be secured to the assembly. To ensure accurate positioning of the body parts 11 (a, b and c) relatively to one another each element B or C is provided with one spigot 12b, 12c, respectively, and three recesses 13b, 13c, respectively, and each element A is provided with two adjacent spigots and two sockets in corresponding positions so that when any two elements are fitted together relative rotation in the separation plane is prevented. The body parts may be other than cubic, e.g. a triangular prism where the arms are to extend at angles other than a right angle relative to each other.

If the gas is admitted also to modify the oxidizing or reducing conditions of the kiln atmosphere, a larger volume may be admitted provided that its speed is sufficient to maintain circulation. The nozzles are provided in the firing zone, and if desired, in the preheating and cooling zones.

[Class 103 (i).] In a regulating-device for motor vehicle &c. brakes of the type in which pivotal stops regulate the " off " position of the brake shoes and are automatically adjusted by them, each brake shoe 1 carries a projection or projections for engaging its stop 10 which is keyed on a pin 11 frictionally held by a spring 12, Fig. 2, so that the stop is manually adjustable from the exterior of the brake dum 5 by turning the head of the pin 11. In one construction the stop 10 is arranged between two projections 8, 14, Fig. 1, on the shoe 1 so that the clearance d equals the normal clearance of the shoe. If this clearance is exceeded the projection 14 rotates the stop when the brake is applied, and on release of the brake the projection 8 abuts the edge 9 of the stop which does not move as the return spring 7 is much weaker than the' spring 12. In a second construction the shoe carries a single projection 17, Fig. 3, moving in a groove 16 in the stop 10 and against the action of the return spring 7. In a modification, the return spring is carried by the stop itself and bears directly on the projection.
