Abstract: 1,027,936. Treating hanks. M. C. FORT. Oct. 19, 1962 [Oct. 19, 1961; Sept. 5, 1962], No. 39718/62. Heading D1L. In the treatment of hanks of yarn 48, hanks are attached at each end to holder 14 in a machine which stretches and widens and possibly brushes the hanks and pairs of holders are joined so that the hanks form a flat chain. The chain is wound on to a beam 7 (Fig. 1 not shown) from which it is drawn through a treatment circuit which in Fig. 1 comprises an array of steam nozzles 3, guides 11, roller guide 2, rollers 1 which guide pins 38 on the holders 14 into clamps 46 (Fig. 9 not shown) on an endless chain device, bath inlets 8, sprays 4, and a reversing section which contains heating or refrigerating tubes 9, a reversing roller 2, a bath outlet 5 and tubes 10 to indicate liquid level. The chain then passes through similar stages in reverse order to be wound up on a further beam 7; alternatively the chain may pass to a further machine without intermediate beaming. The rollers 1 may feed the hanks on to the endless conveyor device in relaxed condition. The material holders 14 may be flat (Figs. 5, 5a, 5b not shown) or cylindrical (Figs. 7, 7a not shown) in which case they have toothed wheels 17 (Fig. 8 not shown) engaging toothed guides 20 so that the holders and thus the hanks are rotated; this is desirable in the mercerizing of the yarns. In other forms the rollers 17 may pass between smooth or toothed surfaces either stationary or moving. Rotatable, perforated spray or suction tubes are shown in Figs. 10, 11, 12.

Title: Telecine machines
IPC: H04N3/38
Filed: 1972-08-25
Abstract: 1412128 Telecine machine BRITISH BROADCASTING CORP 24 Aug 1973 [25 Aug 1972] 39838/72 Heading H4F In a telecine machine, e.g. of the flyingspot scanner type operating on film 12 moving at 25 frames/sec. and with each frame being scanned by the flying-spot scanner 10, registration of the scans from one frame to the next is achieved by detecting when the scan crosses the "rack-bar" between the frames and comparing this instant with the start of the scan to generate or scan correction signal. The rackbar may be scanned by the normal raster scan Fig. 1, giving an accuracy of 1 line, or by a sudden vertical movement 70, Fig. 6, in the scan, Fig. 5, giving an accuracy of 1/16 line. In the finish type, the video output from the photodetector 16 contains a low amplitude part Fig. 3a, for the rack-bar with a rack-bar detector;20 comprising a clamping circuit, high gain dipped amplifier and differentiator Fig. 2 (not shown) producing a pulse at the end t2 of the rack-bar which is used to reset a bi-stable 22. The bistable is set at time t1 by a pulse b from picture pulse generator 24 coincident with every other field sync. pulse. The output of the bi-stable is used to gate line sync. pulses to a counter 30 to give an error signal which, after convertiori to an analogue signal is used to cause a vertical correction in the scanning. In the second type the ¢ field sync. pulse signals P2 cause, by means of a monostable circuit in the picture pulse generator 82, the generation of the vertical deflection pulses P2 causing the rack-bar crossing 70. A capacitor in sample and hold 86 starts to charge when P2 commences, due to P1 setting bi-stable 84 and enabling gate 88 and stops charging when the rack-bar pulse from detector 20 resets the bi-stable. The charge on the capacitor V86 is a measure of the position of the rack-bar relative to the scan and goes to one input of comparator 92. The rack-bar pulse causes the setting of bi-stable 102 via AND gate 104 and reset bi-stable 84 such that gate 100 is enabled to pass clock pulses from generator 98 to clock 96. The clock output (converted to analogue at 94) is applied to the second comparator input such that when the inputs are equal the comparator gives a signal which, via trigger 106, resets bi-stable 102 and stops the count. The count thus represents the position of the rack-bar and is fed to the scanning tube vertical deflection circuit 110. To detect and correct for a twist in the scanning relative to the rack-bar, a pair of rack-bar cross-over scans can be generated at either end of a rack-bar Figs. 9-12 (not shown).

Title: Method of preparing dinitrogen tetrafluoride and nitrosyl fluoride
IPC: C01B21/084
Filed: 1960-11-23
Abstract: <PICT:0895943/III/1> Dinitrogen tetrafluoride and nitrosyl fluoride are produced by reacting nitrogen trifluoride with nitric oxide at 150 DEG C. or above in an inert atmosphere, e.g. N2, A or He.  The molar ratio of NF3 to NO may be from 0,1 to 1 and 10 to 1, temperatures may be up to 950 DEG C. and contact time may be 0,01 sec. to 15 min.  The NO and NF3 are passed from their storage tanks 1, 2 into 3 where mixing occurs.  The mixture is fed into 4a, which is cooled, e.g. by a jacket of cold water, and then into 4b, which is heated, e.g. by an electric resistance coil, and then into 4c which is cooled, e.g. as 4a.  4 is made of or lined with a heat-resistant non-reactive material, e.g. Ni, Al, Cu, stainless steel or Pt. 4b may be packed with inert bodies, e.g. Ni balls and can be heated up to 607 DEG C.  The gaseous product is finally fed into 5, a receiver where it can be liquefied and which can be jacketed with, e.g. liquid N2.  Alternatively the products may be cooled to below 100 DEG C. and treated with aqueous alkali metal hydroxide, e.g. NaOH, to remove NOF, cooled to -180 DEG C. and then fractionally distilled to separate N2F4, which may then be vapour chromatographed, e.g. by molecular sieves.  The NOF may also be removed by contacting the hot products with a metal (preferably other than alkali or alkaline earth).  Both NOF and N2F4 can be obtained from the products by vacuum fractionation which may be followed by vapour chromatography. The NF3 may be prepared by reacting NH3 with F2 or electrolysis of molten fluorides or of urea in anhydrous HF.  NH3 oxidation product gases containing mainly N2 together with some NO are suitable for use as feedstock and diluent.  Specification 758,477 is referred to.

Abstract: 1436424 Cooling dynamoelectric machines; terminal boxes and binding posts GENERAL ELECTRIC CO 28 Aug 1973 [1 Sept 1972] 40422/73 Headings H2A and H2E A terminal box for the high voltage terminal bushings of a multiphase dynamoelectric machine incorporates a flux shield near the parts of the walls of the box which are exposed leakage flux from the bushings, the shield being spaced from these wall parts to define flow passages for cooling fluid from the machine. In the open-top arrangement shown, three housings 4 for three pairs of phase bushings 17 extend away from a curved box wall 1, and a thin conductive flux shield 13 covers wall parts 12 exposed to leakage flux 19. The shield 13 has cut-outs 15 so that when the box is fitted to a machine (e.g. as in Specification 754,175) coolant gas may enter the passages between the shield 13 and wall parts 12, and then flow to a pair of suction manifolds 11, thereby to remove heat generated by flux-induced currents. The box is so shaped that the flow passages have least cross-sectional area and hence greatest fluid flow rate in the regions of greatest leakage flux, as in Fig. 2 (not shown), thereby to produce greatest cooling where needed. The bushings have internal passageways (not shown) for cooling fluid, discharge being via pipes 10 connected to suction manifolds 7. Liquid coolant is also envisaged.

Abstract: 933,218. Lathes. E. C. HAHN, [trading as INDEX-WERKE KOMM. GES. HAHN & TESSKY]. Nov. 17, 1961 [Dec. 17, 1960], No. 41233/61. Class 83 (3). In an automatic lathe, work 50 is transferred from the spindle-nose 92 to another position for further treatment by a bevel-closing collet 30 which is rotatable by a clutch 54, 55 to index the work. A screw 50 may be severed from a stock-bar 94 by a tool 95 and transferred to a grinding station, or one in which intersecting slots are cut in the screw-head by a saw 105, the screw being indexed between saw cuts. A pivoted and axially-movable arm 12 carries the collet 30 in a rotatable sleeve 20 formed with clutch-teeth 55. Co-operating teeth 54 are on a ring 52 pressed by a spring 57 towards the teeth 55 and formed with an inclined slot 60 engaged by a peg 62 on a plunger 69. Movement of the plunger against its return spring 68 indexes the collet, which is held during return movements of the ring 52 by a spring-pressed tooth, Fig. 5 (not shown), engaging locking grooves 80 in the sleeve 20. Alternatively, a screw-and-nut and toothed gears may form the driving elements between the plunger 69 and ring 52. In operation, the transfer arm 12 is moved axially to engage the work, which it transfers to a clamping position, between the spindle-nose 92 and the saw 105, in which the collet is pressed by a stop 96 into the bevel-closing sleeve 20 for clamping the work. The work is then transferred to the saw 105 and moved against the saw, in the direction D. If a second slot is required, the arm is withdrawn to carry the plunger 69 against an abutment and index the work. To eject the work, the arm 12 is withdrawn against a stop (not shown), which engages a collar 45 on the end of the collet, releasing the collet. A resilient ejector with the stop bears on a rod 42 in the collet and ejects the work.
