Filed: 1921-06-20
Abstract: 177,738. Fairweather, W., (Singer Manufacturing Co.). June 20, 1921. Thread-cutters and thread-end holders.-At the end of a stitching cycle, the last needle-thread loop is spread by a looper 80, and one limb is cut by a cutter 39, which bears vieldingly against the underside of the throat-plate p, and co-operates with a ledger-blade 40. The parts 30, 39 are integral with an arm 32, fixed to a sector gear 33, which is actuated from the stop-motion lever in the usual manner. An under-thread severing- blade 26, and a needle-thread nipper 36 are also secured to the arm 32. A forked arm 44 of a slotted lever 43, actuated by an arm 47 of the sector gears, nips the underthread, which is severed by the cutting-edge 29, Fig. 5, of the blade 26. When stitching is re-commenced, the needle descends and the shuttle draws down the loose thread end. The sector gear is then actuated to draw back the thread-nipper 36, which holds the thread-end during several stitches, after which the parts are wholly retracted.

Title: A method and apparatus for the production of filled packages of parallelepiped form
IPC: B65B9/12
Filed: 1964-04-23
Abstract: 1,025,532. Packaging machine. HOLSTEIN & KAPPERT MASCHINENFABRIK PHONIX G.m.b.H. April 23, 1964 [April 24, 1963(2); April 25, 1963], No. 16835/64. Heading B8C. In a method for the production of filled parallelepedic packages from a continuous tube into which a favourable filling material is introduced and in which the individual packages are formed by transverse sealing below the level of material in the tube, the packages are initially shaped by one set of tools and, finally shaped and sealed by a further set of tools, the sets acting in succession and advancing continuously with the tube. The tube 1, of e.g. laminated paper or synthetic plastics foil, is filled continuously so that a uniform level of material is established. Opposite tube walls are initially pressed together by members 3 on chains 4 and the final form of the packages and welding of the seams made by members 8 on chains 7. Members 9 also assist in shaping the packages. Chains 7 move at a lower speed than chains 4 such that the bottom of each package is pushed on to members 8 to effect shaping. Fig. 5 shows the shaping of the tube into packets, which are then severed from the tube (no details given). End portions of the strips forming the areas to be transversely seamed may be turned inwards to form gussets, Fig. 8 (not shown), during initial pressing, by lugs moving synchronously with members 3. Alternatively, the end portions on one side of the tube are turned inwards at alternate seams and the projecting flaps used as pouring spouts. A succession of forming stations may replace the two shown.

Patent GB-648481-A (GB)
Title: Improvements in and relating to the production of alkylated alkylol melamines
Filed: 1948-06-24
Abstract: Alkylated methylol malamines are continuously prepared by passing predetermined quantities of melamine and aqueous aldehyde through a heat exchanger at predetermined temperature, mixing the addition product issuing from the exchanger with a predetermined quantity of alcohol and acid and passing the mixture through a second heat exchanger at predetermined temperature.  The product is raised to a higher pH value, e.g. 8.5-9.5, buffered, vacuum concentrated, and filtered.  The preferred pH in the first step of the reaction is 6-7, and the product of this step is preferably between monomeric and hydrophobic, the degree of reaction being controlled by the time and temperature which is usually within the ranges 1.9 to 6.2 minutes and 207-235 DEG  F.  Similarly in the second stage the degree of reaction is controlled by variation of the pH, time and temperature within the ranges of 5.4-7.6; 1.3-7.4 minutes and 130 DEG  to 320 DEG  F.  The ingredients are preferably delivered in metered quantities from storage tanks fitted with agitators.  The heat exchangers are steam jacketted. Pressure in the system is maintained by a needle valve at the discharge end of the equipment.  In an example, 3.3 mols. of formaldehyde and one of melamine as a slurry of pH 6.3 was pumped through a heat heat exchanger at 215 DEG  F. so that the mixture was subjected to the heat treatment for 3.5 minutes, 10 mols. of methanol per mol. of melamine, containing 0.5 per cent oxalic acid was added to the trimethylol melamine and the mixture pH 6.3) still under continuous flow, was passed through a heat exchanger at 147 DEG  F. at a rate such that any quantity of the mixture took 7.4 minutes to pass through the exchanger.  The methylated trimethylol melamine was adjusted to pH 9.0, flash evaporated to a viscosity of 1290-1760 centipoises and filtered.  The product was buffered, e.g. with triethanolamine, diethyl ethanolamine, sodium bisulphite, sodium sulphite, boric acid, or a mixture of boric acid and potassium chloride.  It is stated that when making pentamethylolmelamine the times and temperatures are reduced, e.g. in the first stage to 1.5 minutes at 115 DEG  C. or 4.9 minutes at 90 DEG  C.

Title: Improvements in and relating to the manufacture of tufted fabric
IPC: D05C15/20
Filed: 1963-05-01
Abstract: 1,020,723. Tufting machines. CALLAWAY MILLS CO. May 1, 1963 [May 3,1962; Nov. 7,1962; March 22, 1963], No. 17097/63. Heading D1G. Tufted fabric is made by positively feeding yarns to the loop-inserting points, and by passing the yarns through holes formed in the backing fabric at said points, by means of fluid streams. Yarns 258 are positively fed in accordance with a predetermined pattern to hollow needles 214 by intermeshing notched bars 262, 264 carried by continuous chains 266, 268 driven by sprockets 270, 272. The needles are mounted in a hollow horizonal bar 244 reciprocated via connecting rods 254 and straps 250 from eccentrics 248 on a rotary shaft 246. The hollow interior 280 (Fig. 10 not shown,)of bar 244 communicates with the bores 274 of the needles via passages 278 formed in the walls of the latter, and is connected via a flexible pipe 298 to an air pressure vessel 302. The backing fabric passes 212 under a presser foot 232 and over a work support comprised by bars extending in the direction of work feed and positioned one on each side of each needle. The bars constitute the lid of a box 220, the interior of which is connected by a pipe 230 to the intake of a vacuum pump 276. The pressurized output of the latter is conveyed via a valve arrangement 312 and a cooler 322 to the vessel 302, the pressure in which is maintained constant by pressure-responsive means 318 operating a linkage 320 to actuate a valve member 314 for directing the output of pump 276 either to vessel 302 or to the atmosphere. Upon a needle penetrating the backing fabric, the yarn passes through the needle under the influence of pressure and suction, to the full extent released by the yarnfeeding means, to form a tuft 216. The tufted fabric emerges from box 220 past the rounded heel 238 of the presser foot 232. A modified needle, (Fig. 13 not shown,) has an upper portion 413 of brass, and a lower fabric-penetrating portion 411 of stainless steel. Portion 413 has an upper bore 410 of greater diameter than an intermediate bar 414 which receives the inlet ends of the inclined air passages 415. Portion 411 is received in a lower bore the diameter of which is such that bore 414 is the same as the bore of portion 411. In the needle in Fig. 16 not shown, the brass portion is made in two separate parts 409<SP>1</SP> and 413<SP>1</SP>. Radial air inlets 427 in part 413 communicate with the bore 414<SP>1</SP> in the latter via an annular space between the tapered end of part 409<SP>1</SP> and a tapered inner wall 426 of part 413<SP>1</SP>. In (Figs. 2 and 3 not shown,) the hollow needle bar 26 carries three rows 102, 104,106 of needles 24, the needles of rows 104 and 106 being positioned between adjacent needles of row 102. Compressed air passes into the needle bar via a duct 62, and passes from the interior of the needle bar into the hollow needles via passages 78 formed in the latter.

Title: Improvements in or relating to the transverse stretching of crystalline polyolefin films
IPC: B29C55/08
Filed: 1962-05-03
Abstract: 1,011,684. Stretching polyolefine films transversely. TOYO RAYON KABUSHIKI KAISHA. May 3, 1962, No. 17105/62. Heading B5B. A crystalline polyolefine film 1 the form of a web may be stretched transversely in a continuous manner by holding its edges by clips 4 mounted in chains sliding on rails which are in three sections 3, 3<SP>1</SP> and 3<SP>11</SP>. The distance between the rails is constant along section 3, increases in the direction of travel of the film in section 3<SP>1</SP> and is again constant along section 3<SP>11</SP>. The film travels first through a preheating chamber A, through which hot air is circulated, then through a stretching chamber B, in which a V-shaped infra-red heater 8 is disposed, and finally through a finishing chamber C in which the film is cooled or heated by passing cooled or heated air through the chamber. Air is prevented from passing between the chambers A, B and C by flexible baffles 6 provided with slots for the passage of the film. During its passage through the chamber B the film is gradually stretched in the transverse direction, the stretching however only taking place within the comparatively narrow area 9 exposed to the heat rays of the heater 8. Thus area D is an unstretched area, while area E is a stretched area. Each rail 3<SP>1</SP> and the corresponding limb of the heater 8 converge in the direction of travel of the film until the lines of clips 4 and the limbs of the heater intersect each other, so that as the film travels through the chamber B the local area exposed to the heat rays is gradually shifted from the central portion of the film outwards to its edges. The locally heated area between the stretched and unstretched areas of the film may have a width of 20 to 100 mm. The unstretched area D is normally contacted with hot air, and the stretched area E with cool air to prevent further stretching therein. The film may or may not have been previously stretched in the longitudinal direction. The linear infra-red heater 8 may extend from one edge of the film at the inlet of the stretching zone to the other edge of the film at the outlet of the stretching zone instead of from the central area of the film to both its edges as shown in Fig. 3a.
