Title: Twine jointing method and machine therefor
Inventor: WILLIS GRANT NOBLE
IPC: B65H69/06
Filed: 1953-10-28
Abstract: 756,960. Connecting the ends of cordage &c. PLYMOUTH CORDAGE CO. Oct. 28, 1953, No. 29847/53. Class 109. A twine jointing machine, adapted to join together overlapped lengths of twine by winding a length of wire helically about the said lengths, comprises a pair of coaxially aligned wire winding spindles formed with central aligned passages for the overlapped lengths of twine and with offset passages for wire, and also comprising driving means for rotating the spindles in opposite directions and imparting an axial separating movement to the spindles during such rotation. The cam-shaft 27 of the machine is driven by a motor 34 (not shown) through a one-revolution clutch 36 tripped by a button 56. The shaft 27 drives an arm 37 connected to a spring-tensioned sprocket chain 38 passing over a pawl-operated sprocket 39 on a wirewinding spindle-driving shaft 28, the arrangement being that for about 100 degrees of rotation of the arm 37 the sprocket 39 idles, after which the pawl 44 drives the shaft 28 through 180 degrees, followed again by an idling motion. Splined to the shaft 28 are gears 50, housed in transversely-movable carriers 48, 58, which through trains of gears 51, 52, 53 rotate the wire-winding spindles 14, 15, the carriers 48, 58 being moved toward and away from each other by cams 68, 70 through followers 67, 69. The spindles 14, 15 each comprise a gear portion 16, an axial bore 17, 21 for the overlapping lengths of twine, and an eccentric passage 19 for the cut length of binding wire, the passage 19 merging at 20 with the axial bore. The twine 12 from a container 116 (not shown) is led through a tension block 117, having a spring- biased twihe-gripping dog 124, thence placed by hand about a package and the free end 11 put beneath a pivoted clamp 98. The overlapping twine ends are introduced into the spindles 14, 15 through sector-shaped radial throats 18, and tension is applied to the twine by movement of the block 117, with the carrying arm 119, by the cam 121. Wire 13, from supply, is drawn by a gripping device 76 operated by a cam 78, through an arm 77, and fed through the passage 19 of the spindles 14, 15, the leading end portion being cut off by a lever 80 operated by a cam roll 83. As the spindles begin to turn and separate, gripping arms 85, 86, operated by a cam 90 through a lever 88, move into gripping engagement with the length of wire 13 and the overlapping ends of twine (Fig. 19). When the wire-winding is completed, cam-operated arms 114 move cutters 99, 107 to cut off the twine ends held beneath the clamping dog 98 and the twine extending back to supply, respectively. The cams 68, 70 are so formed that the outer wire helices are close together, the spindles 14, 15 being moved towards each other to " wipe " the endmost wire coils into their finished shape (Fig. 21). Specification 717,198 is referred to.

Filed: 1936-11-03
Abstract: 468,178. Hand-sewing tools. GOSTKOWSKI, B. H. Nov. 3, 1936, No. 29935. Convention date, Nov. 8, 1935. [Class 112] Relates to a latchneedle for use in machines for repairing runs in fabrics. The profiled front surface of the needle body consists of a portion 6, parallel to the rear of the body, a notch 7, contained, with the exception of a negligible portion, within a circle k having the axis 4 of the latch 3 as centre and drawn tangentially to the needle hook, and a swell 8. In the open position the latch is received in its entirety in the notch and its blunt point 19 is situated between the bottom of the notch and two tangents t<1>, t<2>, drawn respectively through the axis of the latch touching the profiled surface behind the notch and through the point of intersection of the circle k with the profiled surface, touching this profiled surface near the swell 8. The tangent t<2> also cuts the needle hook. The two lines defining the edges of the latch intersect at a point s about twice the length of the latch from the axis 4, that line defining the rear edge, passing quite close to that axis. In the closed position the point of the hook enters a recess in the latch. An L-shaped spring 11, Fig. 2, opens the latch, its longer arm then contacting with the rounded end 9 of the latch, to exert a braking effect, the spring being then practically entirely contained in the needle body. The open position of the latch is limited by an abutment 12 in the recess in the needle body. The needle profile described is said to make possible a high working speed in even the finest knitting.

Title: Improvements in or relating to the treatment of textile fabrics
IPC: D06M13/144
Filed: 1935-11-01
Abstract: Fabrics containing yarns having a basis of an organic derivative of cellulose are shrunk by means of an aqueous solution of a lower aliphatic alcohol, preferably a 20--80 per cent solution of methyl or ethyl alcohol used for 4--8 mins. at normal temperature or for \ba1/2\be--3 secs. near its boiling point.  The alcohol solution may be applied to the fabric by immersion or by spraying, and excess solution removed by passing the fabric through nip rollers covered with absorbent material such as linen or cotton.  The treatment may be used for producing antishrink fabrics, or for producing fabrics of a closer construction than is p  possible by weaving.  Fabrics treated according to the invention also exhibit a reduced tendency of the weft to slip on the warp. In an example, a taffeta fabric consisting wholly of yarns containing cellulose acetate is immersed for 1 sec. in a bath at 88 DEG  C. containing 4 parts of water and 1 part of ethyl alcohol, squeezed and dried; a shrinkage of 17 per cent in the warp direction and 11 per cent in the weft direction results, giving a tightly woven taffeta.  Specification 408,654 is referred to.

Title: Improvements relating to the manufacture of crude rubber
IPC: C08C1/08
Filed: 1931-11-02
Abstract: Preserved latex is separated into two layers by a creaming process, and the heavier layer, poor in rubber and rich in non-caoutchoue ingredients of the latex, is treated to obtain the whole of the solids without denaturing the proteins.  The usual creaming agents are employed in such proportions and for such time as to obtain a lower layer having the desired proportion of rubber to non-rubber constituents.  The creaming may be followed by centrifuging.  Spray drying is the preferred method of removing the water.  The rubber thus obtained may have a caoutchouc content as low as 20 per cent, and may be used alone or in admixture with ordinary crude rubber to modify its properties.  This rubber has the same tensile strength as first grade rubber with less stretch, is fast curing, ages well, and has a high resistance to tearing. Examples of various mixes and their properties are given in the Specification.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the separation of the latex into two portions by centrifuging alone.  This subject-matter does not appear in the Specification as accepted.

Heading G6C. A solid moderated nuclear reactor having fuel channels located in the moderator core has charge pans near a surface of the core but supported independently of it, the charge pans having holes or tubular extensions aligned with the channels. The reactor comprises a gas cooled graphite core 1 in a steel or concrete pressure vessel 3; if the vessel is steel, it is surrounded by a concrete biological shield. Standpipes 4 have tubular guide extensions 5 for fuel elements and control rods. The charge pans, only one of which is shown in the drawing, are supported either by the guide tubes as shown or by other suitable means, independently of the core. The extensions 6b, 6c are a clearance fit in the upper ends of the core channels 2; alternatively, they may be a close fit, relative movement between the core and charge pans being catered for by mounting the extensions 6b, 6c pivotally in the plates 6a. It is preferred to mount all but one of the extensions in this way, the exception being the centremost extension associated with a given charge pan which would be rigidly secured to the charge pan to maintain alignment of the charge pan with a given area of the core face. Fuel element leak detection. Frequently coolant sample tapping points are located in the charge pans, and include sample piping supported by the guide tubes; the failure of such piping due to relative movement of the charge pans and guide tubes is avoided in the present invention.

Abstract: 745,278. Sawing. CARVER & CO. (ENGINEERS), Ltd., and CARVER, L. J. Nov. 30, 1954 [Nov. 5, 1953], No. 30553/53. Class 145. A machine for cutting two bars 1, tubes or strips disposed side by side comprises a saw 2 or other cutter given an oscillatory or reciprocatory feed motion to cut through first one and then the other and each bar is gripped by a movable jaw automatically operated to grip it during cutting and release it after cutting. Two sets of movable jaws 14, 15 are provided between two sets of fixed jaws 12, 13 and each bar is fed by a slider 4 which has a rubber or other pad 56 and is connected by a cable 5 to one of two pulleys 7 on a shaft 8 rotated by cables 11 and weights 10. A hinged handle 55 can be hooked over the end of the bar support table 3 to hold the slide in inoperative position. The pair of separate movable jaws 14, 15 are arranged to grip the bar on both sides of the place to be cut and the movable jaw 14 that grips the cut-off part may be arranged to release in advance of the other movable jaw so that stock cannot be fed forward until the cutoff part has fallen clear and exposed a feed stop 42. A motor 21 carried by bracket 23 pivoted on a shaft 22 drives the saw 2 and also, through a variable-speed pulley 29, reduction gear 31, crank 33, link 35 and crank 34, oscillates a rock-shaft 28. By means of a crank 27 and link 26, the rock-shaft oscillates the motor 21 so that the saw, operating in jaw gaps 17 and 18, moves backwards and forwards in an arc to cut first one bar and, on the return stroke, to cut the other bar. A pair of cranks 39 on the rock-shaft 28 carry a pin 38 which can engage the tails of jawcarrying levers 36, 37 pivoted on the shaft 22 and, as the pin 38 moves away from the levers for one set of movable jaws 14, 15, to allow springs 41 to move them to gripping position on one bar, it engages the levers for the other set of jaws 14, 15 to release the other bar so that it can be fed up to the stop 42 by its slider 4. The lever 37 for the jaw 15 engaging the stock may have a cranked tail 40 so ;that release of the stock is delayed until the other jaw 14 has released the cut-off part into a shoot 43 or 44. The forward ends of the jaws 12, 15 are shaped to provide leads and the fixed jaws 12, 13 are mounted in a carrier 16 on a platform 47 held in adjusted position by bolts 49 and a clamping plate 50. A coarse adjustment of the end stop may be obtained by adjusting a block 58 along a slot 60 in the carrier 16 and a fine adjustment by means of the screw on the stop itself. The throw, of the crank 27 is adjustable by securing the link 26 in one of several holes in the crank.
