Patent GB-673776-A (GB)
Title: Improvements in the manufacture of carbon black
IPC: C09C1/50
Filed: 1950-06-12
Abstract: Carbon black is produced by flowing a gaseous stream composed wholly or in part of hydrocarbons containing not less than two carbon atoms per molecule as a confined stream into a highly heated zone containing reactive oxygen, the temperature of the zone being at least as high as the hydrocarbon kindling temperature, and shielding the gaseous stream for a substantial distance within the zone by flowing in contact with and surrounding it a stream of combustible gas free from oxygen, e.g. natural gas, or oil refinery tail gases, and supplying heat for decomposing the inner stream by combustion of the outer stream. This process may be applied to any furnace carbon black process, but is particularly described and illustrated in relation to (1) a free flame process wherein hydrocarbon make gas streams flow into a quiescent stream of air flowing up and around the make gas streams in a furnace chamber, and (2) a blast flame process wherein make gas is injected, in a direction parallel or at right-angles to the axis of the furnace chamber, into a turbulent stream of blast flame gases, produced by combustion of air and fuel gas, flowing through the furnace chamber.  The make gas injection tubes described consist of a thin walled metal tube enclosed in a concentric refractory tube and the end is preferably recessed from the end of the refractory tube to prevent unnecessary coking.  The ratio of the velocities of the inner to the outer streams should be 0.5 : 1 to 6 : 1 to prevent excessive turbulence.  Specifications 654,864 and 655,799 are referred to.

Filed: 1946-05-07
Abstract: 613,502. Making heat-exchangers. FORD MOTOR CO., Ltd., and LEEK, J. W. May 7, 1946, No. 14675/48. Divided out of 613,472. [Class 83 (ii)] A machine for making radiators of the kind having a plurality of metal tubes passing through a number of parallel metal fins, comprises means for forming the tubes into an assembly in which the individual tubes are relatively arranged in positions corresponding to those which they are required to assume when inserted within a stack of fins. The tubes 3 are loaded into a hopper 55 having partitions forming a number of parallel slots. Longitudinally and rotatably mounted at the side of the hopper is a spindle 61, Fig. 2, carrying a trunnion 60 on which is mounted a nest 56 comprising a box-like member half the length of the tubes and having slots to receive the tubes and a terminal or end-plate 57 supported from the nest by rods 58. The nest is first swung about the trunnion 60 into a horizontal position in line with the hopper, this movement operating a lever 91 which opens a valve 92 causing the supply of pressure fluid to a cylinder 62 and the actuation of a piston 67 which is formed with a rack and rotates a shaft carrying the driving sprocket 69 of an endless chain 70, Fig. 3. This chain carries a push plate 93 which is moved along the bottom of the hopper 55 and pushes the lower row of tubes into the nest. At the end of its stroke the plate 3 actuates a valve 63 which causes the operation of a lever 96 so that the spindle 61 is lowered by a rack and pawl mechanism ready to receive a second row of tubes. Lever 96 also operates a valve 95 to return the piston 67 ready for another operation of the push plate 93. After the third traverse of the push plates, the nest is filled with three rows of tubes and the valve 92 is automatically tripped to stop further movement of the loading mechanism.

Patent GB-919082-A (GB)
Title: Method of, and apparatus for, yarn end control in knitting machines
IPC: D04B15/60
Filed: 1960-04-27
Abstract: 919,082. Knitting-machines. SINGERFIDELITY Inc. April 27, 1960 [April 28, 1959], No. 14708/60. Class 74 (2). The severed end portion of a withdrawn yarn 21 fed by one, 15, of a number of guides 14, 15, 16 at a feeder of a circular machine, is twisted with the ends of other inactive yarns of the other guides to form a strand 23 to retain it in an inoperative position whereby the yarn is ready for subsequent feeding to the needles. On introduction of a yarn 28 by its guide 14 to the needles, the end portion of the yarn extending from the first receiving needle to the strand, into which it has been twisted with the other yarns, is severed to release the end portion from the needles after which the severed end portion is gradually withdrawn with the strand into a waste receptacle. As illustrated in Fig. 1, the withdrawn yarn 2 is being drawn by the last needle to take it under a clamp 26 and subsequently under a deflector 29 until the yarn extends diametrically across the needle cylinder on top of the dial plate 13. The yarn 21 then comes into contact with a heater element 33 which severs the yarn and, simultaneously, a hollow spindle carrying a hook 36 at its lower is rotated so that the hook engages the end of the yarn 21 and twists it together with the other yarns extending from the guides to form a single strand which passes up through the centre of the spindle where a flyer head is provided for engaging the strand and periodically drawing the strand up through the spindle into a waste receptacle. When a yarn is reintroduced to the needles, as shown by the yarn 20 in Fig. 2, the yarn extending from the spindle 24 to the guide 14 is engaged by the leading needle and is gradually peeled from the strand to pass beneath the clamp 26, over the leading end of the deflector 29 to be engaged in a hook portion 30. As the leading needle draws the yarn extending from it to the spindle into engagement with the heater severing device 33, the hook 30 of the deflector 29 holds the yarn out of engagement with the spindle hook 24 so that it is not again twisted into the strand but so that the severed end is eventually drawn up through the spindle with the rest of the strand by the flyer head. Specification 919,083 is referred to.
