Title: Improvements in or relating to electric incandescent lamps
IPC: A01D11/02
Filed: 1935-08-19
Abstract: 450,371. Electric incandescent lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Aug. 19, 1935, No. 23254. Convention date, Oct. 8, 1934. Drawings to Specification. [Class 39 (ii)] Electric incandescent lamps which have a gas filling substantially consisting of krypton, xenon, or both these gases, or a filling of other expensive gases which can be advantageously used anew in a new lamp, are provided with an indicating material which is contained within the bulb, and, upon reacting with a constituent of atmospheric air, changes its colour. In the example, the change of colour of the indicating material is effected by the water vapour present in the air, suitable materials which react in this manner comprising a cobalt compound, more particularly a complex cobalt compound such as cobaltocobaltcyanide. As a result of reaction with water vapour this compound changes from a blue colour to a bright red. A similar change of colour is shown by hydrazoniumcobaltohalide, while the blue colour of nickelous cobalticyanide is turned into green by water vapour. The indicating material may be applied to a strip of paper which is introduced into the bulb prior to the mounting of the other internal members of the lamp. A cobalt compound, which is blue when dry, is preferably applied to an inert blue background, so that a bright red spot becomes visible if air should penetrate into the bulb. In the example, the indicating material is applied to the stem of an electric incandescent lamp.

Filed: 1966-05-26
Abstract: 1,149,365. Dobbies. STAUBLI & CO., GEB. 26 May, 1966 [1 June, 1965], No. 23532/66. Heading D1E. A reversible double-lift open shed dobby has reading needles 38 to 41 which act on two rows of draw needles 28-30 and 29-31, the needles 29-31 being acted on by a draw rail 35 for forward running and the needles 29-31 being acted on by a draw rail 34 for reverse running. The draw rail 35 has notches and is movable transversely so that it operates alternately on the needles 29-31 which are connected to upper and lower arrester hooks 10, 11 respectively. Similarly the draw rail 34 acts on the hooks 10, 11 by way of the needles 28-30. The draw rails are reciprocated out of phase with each other so that, during forward running and after selection of the needles 29- 31, the draw rail 34 passes ineffectively under the needles 28-30 when they have been raised by a lifting rail 36 to allow the pattern drum to turn. Similarly, for reverse running and after selection of the needles 28-30, the draw rail 35 passes ineffectively under the needles 29-31 when they have been raised by a lifting rail 37 to allow the pattern drum to turn. The reading needles 39, 41 act on the draw needles 29-31 and the reading needles 38, 40 act on the draw needles 28, 30 and the draw needles, when selected, are moved by their respective draw rails to tilt the arrester hooks 10 or 11 so that an attachment hook 9 or 9' may engage with its arrester hook when the baulk 6 is oscillated by bars 7 or 8.

Abstract: 719,554. Friction clutches; combined clutch and brake. HARRIS, H. G. Jan. 12, 1953 [Oct. 12, 1951], No. 23858/51. Class 80 (2) [Also in Group XXXIV] A magnetic clutch comprises a rotatable member of magnetic material, means for magnetizing said member, two associated members of magnetic material on either side of said first member, one or both of said associated members being rotatable, and additional electromagnetic means to change the flux pattern at least temporarily to couple said first rotatable member with one or other of the associated members. In one form, an axially slidable driven disc 24 of magnetizable material on a shaft 27, lies in a hole in a standard 31 of magnetizable material surrounded by a coil 36, and can be frictionally engaged with one or other of two .driving discs 14 of magnetizable material in recesses in the ends of two standards 1 of magnetizable material surrounded by coils 37. In the mean position shown, current through the coil 36 produces a flux pattern equally disposed on either side of the driven disc 24, which accordingly remains undisturbed in its central position. To engage the driven disc with one or other of the driving discs, a pulse of current in the appropriate direction is passed through the coils 37, the flux of the coil 31 then maintaining the engagement. If the clutch is to transmit large torques, a continuous current may be passed through the coils 37. Gears 22 are secured to the driving members 14 and may be driven at different speeds or in different directions, or one may be rotated while the other is held stationary. As a modification, one of the coils 37 can be replaced by a permanent .magnet which always biasses the driven disc in one direction, a continuous current in the other coil being used to oppose and overcome the flux of. this magnet. Alternatively both coils 37 can be continuously energized in such a way as to oppose each other, the clutch being engaged by switching off the supply of current to one of them. Again, the currents in the two coils can be made to correspond to the instant value of a varying electric signal, so that, with the two gears 22 driven in different directions, the driven disc 24 will execute a rotary oscillating motion of small amplitude. In a modified form, Figs. 2, 3 (not shown), the driven disc lies within the hole in a ring-shaped permanent magnet having one polarity at its inner periphery and another at its outer periphery, the coil 36 being dispensed with.

Abstract: 794,673. Feeding webs. ABELL, Sir G. E. B., TILLEY, D. W., and PRICE, P. R. Aug. 17, 1956 [Aug. 18, 1955], No. 23879/55. Class 100(1) An apparatus for facilitating the inspection of a web travelling at a high speed comprises means for locally reducing the web speed, or stopping the web, at a viewing station to enable successive sections of the web to be examined, such means including an endless succession of spaced web supports for supporting sections of the web, means for moving the succession of supports past the viewing station in the direction of web movement, an endless succession of web-diverting members, means for moving the diverting members in the direction of web movement in staggered relation with the web support devices, means for moving the diverting members into the spaces between the support devices as they approach the viewing station to push the web between the support devices to form a succession of loops alternating with a succession of sections for viewing, and means for withdrawing the diverting members from the spaces after leaving the viewing station. As shown, the inspection apparatus comprises two chain systems 10, 11, the upper chain system 10 having spaced apart chains 12 passing around sprockets 13 and the lower system 11 having chains 14 passing around sprockets 15. Rollers 18 are provided on the chains 14 so as to extend laterally thereof. Rollers 19 are mounted on the free ends of arms 20 pivoted on chains 12 so as to co-operate with a pair of rollers 18 to form loops in a web 26 to be inspected. Cam surfaces 21 engage the arms 20 to control their position so as to form loops in the web on entry into the apparatus and release such loops on exit from the apparatus. As the rollers 19 and 18 approach horizontal lays 16 and 17 the parts 22 of the cam surfaces cause the rollers 19 to descend between a pair of rollers 18, the rollers 19 being maintained in this position until parts 24 of the cam surfaces 21 cause the rollers 19 to ascend. The web is inspected at the tops of its loops while positioned horizontally between successive rollers 18 moving in the same direction as the web 26, but at a lower speed than that which it enters the apparatus. The speed of the chains 12, 14 may be chosen such that the portions of web 26 at the tops of the loops moves forwards, backwards or are stationary with respect to the rollers 18, 19. The upper and lower rollers may be driven about their axes by endless chains at the same speed as the web passing over them.
