Abstract: 641,063. Sewing. PARKER, H. E. Sept. 6, 1948. No. 23374. [Class 112] Darning. - A device for use in darning comprises two flat members 1, 2 to be fitted together with the work between them, the opposing faces of the members being formed with interfitting corrugations as shown and the crests of the corrugations being grooved to provide needle passages across the corrugations. In the form shown, the member 2 has dowel pins which pass through the work into holes in the member 1. After one set of parallel threads is placed in the work the device is detached and turned through a right-angle for completion of the darn. The channels may be straight or wavy, and the needle channels are preferably perpendicular to them. A test hole for selection of the right size of needle may be formed in one plate. According to the Provisional Specification the channels may be in the form of circles or other closed figures, in which case intersecting sets of grooves may be provided to allow the darn to be completed without removing the device from the work; the crests between adjacent channels may be formed by a number of rollers, either coupled together and actuated by the fingers or free' to be moved by the thread; the plates may be held together magnetically or by sliding members engaging the dowel pins or their equivalent, or by the elasticitv of the material engaging parts of reduced diameter behind the points of the dowel pins; the plates may be reversible. with different arrangements or dimensions of channels or indentations on the two faces, and they may be roughened to grip the material better; the plates may be slightly flexible, and may be formed in two or more parts hinged together or interlocked and separable.

Abstract: 447,537. Two - stroke - cycle engines. KADENACY, M., 120, Rue Lecourbe, Paris. Aug. 14, 1934, No. 23472. Drawings to Specification. [Class 7 (ii)] The outflow of exhaust gases is used to induce a fresh charge by atmospheric pressure through an admission orifice which is opened after the exhaust orifice opens, but only with the delay required to ensure that the exhaust gases are moving outwardly through the exhaust orifice or duct, a supplementary charge being introduced at a pressure higher than atmospheric, preferably separately from, and at or about the end of the period of introduction of the main charge. The main admission port and the exhaust port may be at the same or at opposite ends of the cylinder, and closure of the exhaust port may either precede or follow that of the admission port. Where the exhaust and inlet orifices are at the same end of the cylinder, pockets of burnt gas at the other end may be dislodged by a valve at that end controlled to admit a small quantity of air.

Tricresyl phosphate is added in Example (7) and n-butyl glycidyl ether is used as an alternative to the epoxyalkyl ether of (B) in a comparative Example (9).  In another comparative Example (6), the diglycidyl ether of bis-phenol-A is used instead of the blend.  Uses.  Glass fibre laminates (see Group VIII), castings, sheets and filaments.  Reference has been directed by the Comptroller to Specification 675,180.ALSO:In examples, polyglycidyl ethers are prepared by reacting epichlorhydrin, NaOH, and (1) tetrachloro-p,p1-isopropylidene diphenol, (2) trimethylolpropane, and (3) 1,4-butane diol.  The haloaromatic and the aliphatic polyglycidyl ethers are then blended and cured to form flame-retardant materials (see Group IV(a)); alternatively the blend may be prepared by reacting epichlorhydrin, NaOH, and a suitable mixture of polyols.

In a fluid-flow controlling valve where the valve chamber constitutes a cylindrical enlargement of the fluid duct, the flow from the valve inlet 75 via passages 66 to the outlet 69 is controlled by a valve 65 carried by a piston 64 in a cylinder 63 communicating with the inlet via a constriction 73 and with the outlet via by-pass passages 76, 81, 84, 86 controlled by a hand-operated valve which may be a diaphragm 77 or a needle valve. The end of the valve is hemispherical and concentric with the internal wall of the casing, and the valve and piston may have buoyancy chambers to give them the same effective specific gravity as the fluid flowing through the valve. With the pilot valve open, the fluid pressure acting on the valve tends to open it, while with the pilot valve closed, the cylinder pressure is greater than the pressure acting on the valve and closes it. If the pilot valve is progressively adjustable, the valve 65 assumes various positions between fully opened and closed. The pilot valve may be actuated by an electromagnet in the part 62 and the piston may be lightly spring-loaded.

Title: Improvements in and relating to a method and apparatus for loosening tightly wound reels of strip
IPC: B21C47/26
Filed: 1962-06-25
Abstract: 949,014. Feeding webs. SCHLOEMANN A.G. July 25, 1962 [July 25, 1961], No. 24275/62. Heading B6B. [Also in Division B3] A method of expanding a tightly-wound reel of strip into a spirally-expanded shape, with gaps between the individual turns comprises placing the tightly-wound reel with one end face on a support equipped with a fixed non-rotating core and expanding the outer turn of the reel until it forms a sufficiently large circle and may be mounted on a rotatable cylindrical outer shell surrounding the support and reel so that, with rotation of the outer shell in the appropriate sense, entraining the leading end of the strip, the turns are successively pulled off the smaller diameter tight reel and form a larger diameter reel, and during the pulling off of the individual turns a force delaying the radial expansion movement is applied by means of which the turns are prevented from resting firmly against the preceding turns. A tightly-wound reel 8 is secured at its inner end to a central core 9 on a baseplate 1 and is supported on a fixed ring 3 and on rings 4, 5, 6 and 7 rotatable on a dished ring 2 rotated by a pinion 11. The outer end of the strip is secured to the inner wall of a cylindrical shell 12 carried by the ring 2 and concentric with the core 9. As the shell 12 rotates, turns are successively detached from the reel 8 and move towards the shell 12. Magnets 14 restrain the expansion of the reel so that a loose coil 8a is formed in the shell 12. The magnets 14 are fed in radially by means operated by rotation of the shell 12 and are vertically adjustable in guides 13. In another embodiment, Fig. 3 (not shown), the magnets are replaced by a cover-plate covering the entire end face of the reel and supported by the shell 12, air displaced by a turn preventing it from resting tightly against the previous turn. A medium heavier than air, e.g. carbon dioxide, may be introduced into the apparatus. In a further embodiment, Fig. 5, a tightly-wound reel 21 is supported on conical rollers, each subdivided into sections 22a, 22b, 22c and with their axes inclined slightly to planes radial to the reel 21. The end sections 22a are rotated by gears 26 meshing with a rotated ring 27 while the sections 22b, 22c are loosely mounted on the idler spindles. An outer shell 34 is supported and rotated by the rollers and guided by rolls 35.
