Filed: 1939-03-07
Abstract: 526,044. Lipstick cases. YOUNGHUSBAND, J. L. March 7, 1939, No. 7347. [Class 18] In a -case to hold a lipstick 27 which can be slid up or down in the outer casing 10, the cup 20 holding the lipstick is attached to one end of a resilient strip 46 which also engages a rotary member 47 so that, as the latter is rotated by means of an external knob, crank, &c., the lipstick is caused to project from or be retracted into the case. As shown, the member 47 comprises a cogwheel the teeth of which engage apertures in the strip 46, but it may comprise a plain roller of non-slip material engaging a plain strip 46, or the roller may be flanged and be capable of being turned by means of the flanges which project through the base of the case. A groove 50 on a projection in the base ensures that the strip contacts with the cogwheel or rollers. The casing is angular in cross section and the free end of the strip moves in one of the corner spaces between the cup 20 'and the casing, but in a modification, this end of the strip is attached to the member 47 and is wound up thereon as the latter is rotated. A separate plate with a bent up tongue may be positioned under the member 47 to form a guide for the strip 46. The cup 20 and lipstick may be surrounded by a cylindrical sleeve formed with a longitudinal slot in which slides the pin connecting the cup to the strip 46 and, in the ense where the casing 10 is also circular in cross section, the free end of the strip moves in a second diametrically opposed slot. A base cup 34 and a top cup (not shown) fit on to recesses in the ends of the casing.

IPC: F21K5/00
Filed: 1923-03-14
Abstract: 217,316. Drake, W. B. March 14, 1923. Magnesium and like powder lamps. - A flash-powder lamp for photographic purposes comprises a sheet metal trough A and an igniting means consisting of a grooved or milled wheel K which is carried by a spindle I arranged in a tube B attached to the trough floor and engages two screw-adjusted spring- pressed flints M<1> carried by tubes M also attached to the trough floor. A spring-pressed ratchet E mounted in a holder C on the tube B engages a ratchet-wheel H on the bottom of the spindle I. When the ratchet-wheel H is released by pressure on the ratchet E the spindle I is rotated by a coiled spring G and the sparks caused by the contact of the wheel K with the flints M<1> ignite the flash powder in the trough A. A removable metal cover L formed with spark apertures 0 prevents contact of the powder with the wheel K. On the spindle I being rotated to put the spring G in tension the grooves of the wheel K are cleaned by contact with the flints M'.

An electric blasting cap is provided with a fuzehead comprising a dielectric sheet 20 having on one side spaced electrodes 16, 16<SP>1</SP> connected by a wire 9 bridging a gap 17 in the sheet. Closing the metal shell 1 of the cap is a resilient plug 8 formed in two halves between which the sheet 20 is so sandwiched that the bridgecarrying portion is exposed and dips into an igniter composition 5 housed in a cup 4 of polyethylene or like material. This arrangement is said to minimise danger due to 'arcing'. A sleeve 14 filled with a delay mixture may be placed between the fuzehead and a primer charge 3 overlying a base charge 2. The fuzehead may be formed by a "printed circuit" technique, the electrodes being a copper or other metal coating applied by vapour deposition on to a support of plastic material such as polyethylene terephthalate or on to glass or mica, surplus metal being subsequently removed by chemical or mechanical means before soldering the wire 9 in position. The delay charge may be an 85/15 barium oxide-selenium or a 2/98 boron/red lead mixture, which latter mixture may also be used as the igniter material 5. The primer 3 may be lead azide and PETN may be used as the base charge. The plug sections have parallel grooves to receive leg wires attached to the electrodes.

Abstract: 590,922. Automatically adjustable couplings. ROTAX, Ltd., and MILLER, D. K. March 26. 1945, No. 7555. [Class 80 (ii)] [Also in Groups XXVI and XXXVII] Centrifugal mechanism for use in a sparktiming coupling in internal-combustion engine ignition, for actuating electric switches, or for other purposes, is adjusted suddenly from one limit position to the other above a predetermined speed, by means of two centrifugal forces at right angles, one of which acts on masses i having pin and radial slot engagement k with a driving disc a and carried on curved arms e providing the other centrifugal force and pivoted symmetrically at h on a driven member d, the arrangement being such that initially a line joining the mass centres k to their pivots h passes through the centre-line of the driving and driven members a, d, so that the masses i are without effect and the coupling remains locked until the smaller centrifugal force, acting on the arms e at right angles to the mass radiusline h h, moves the masses away from the radius-line, whereupon the centrifugal force on both masses and arms acts together to move the coupling suddenly to its other limit position against return springs n.

Title: Process and apparatus for the continuous manufacture of crimped threads or fibres of polymeric -e-caprolactam
IPC: D06B3/16
Filed: 1954-03-16
Abstract: <PICT:0750652/IV(a)/1> In the continuous production of crimped fibres or threads of polymeric e -caprolactam, the fibres or threads are stretched whilst still containing lactam, are mechanically crimped, washed without tension in hot water to remove the lactam, and dried without tension, whereby the stability of the crimp is improved. The stretching may be carried out in several stages at successively rising temperatures, up to 200 DEG  C., and may include a stage in which stretching is effected in an atmosphere of steam at 95-105 DEG C.  The subsequent washing, which removes monomeric and low polymeric constituents, may be effected in water at a temperature rising in stages above 80 DEG  C., and may be effected without tension.  In the apparatus shown, a mechanically crimped sliver is fed by rollers 5 and laid by known means (not shown) in the perforated conical container 2 immersed in tank 1.  The sliver is drawn out at the bottom and over guide 4 by rollers 6.  In an example, a newly spun card sliver of polymeric e -caprolactam containing about 7 per cent monomeric lactam and also di- and trimeric lactam is cold stretched to 3.4 times its length, mechanically crimped and washed with water at 92 DEG  C. without tension in the device shown, until free from lactam.  After drying and cutting the fibres showed a crimp stability of 6 per cent compared with the usual 45 per cent.

Abstract: 577,395. Recording polar reflection curves. BIRD, G., and MACLEAN, D. J. April 25, 1944, No. 7697. [Class 40 (iii)] Apparatus for recording polar reflection curves comprises a source for illuminating a test surface to be examined and a photoelectric cell receiving light from said. surface and connected to a galvanometer having a light spot which falls on a sensitized surface to produce a photographic trace, the source, the test surface or the photo-electric cell being moved relative to the other two elements for varying the angle of incidence or reflection of light reaching the cell. The sensitized surface follows the movement of the moving element to cause the trace to be drawn out into the required curve. In the arrangement shown, the test surface is mounted at 6 on an axis about which U-shaped arms 5 and 22 are pivoted, arm 5 carrying the photo-electric cell 8 and arm 22 carrying the light source 7. Arm 22 is adjustably bolted to plate 23 and arm 5 may be bolted to plate 25, but for the production of the required curves is driven by motor 9 through an angle determined by limit switches 12 and 13. The galvanometer is mounted in a box 18 and its spot moves along a slot 17 in a camera 15, the slot extending radially of the axis of rotation of arms 5 and 22. Within camera 15 is a member moving with arm 5 and carrying sensitized paper on which the trace is produced. The galvanometer " spot is preferably in the form of a line transverse to the slot.
