Title: Improvement in cosmetic container
IPC: A45D40/02
Filed: 1934-07-21
Abstract: 430,695. Reservoir brushes. GIMONET, A., 27, Old Town Road, Arrochar, Staten Island, New York, U.S.A. July 21, 1934, No. 21411. [Class 19] [See also Groups XVII and XXVIII (Appx.)] The closure member 13 of a cosmetic container is automatically opened by the holder 12 as the stick 30 is projected. When the stick is within the container, the points 22 of the closure member 13 contact with the casing 11, thus bringing the edges 24 together, whilst contact of a member 31 with an edge 45 of an auxiliary closure member 14 tilts this member to close the notch 16 in which the member 31 slides. Upward movement of member 31 causes it to engage with a cam portion 46 on the member 14, which, in turn, has projections 37, 39 engaging in notches 26, 40, in the member 13. This, together with the friction between the holder 12 and the closure member 13, raises the latter until the points 22 are clear of the casing 11, when the resilient arms 17, 18, fly apart to allow the cosmetic stick to protrude. When the operation is reversed, a projection 42 abuts on the base of the closure member 13 and lowers it. In the modification shown in Fig. 9, the cosmetic is contained in a holder 59 and is extruded therefrom by a plug 65, operated by a knob 71 ; the holder 59 is urged out by a spring 74, when a catch is released. Bristles may be arranged at the opening 63. In a further modification, Fig. 7 (not shown), the notch and the member 31 are made narrow and the auxiliary closure member 14, and the projection 42 are eliminated. In a still further modification, Fig. 8 (not shown), a cosmetic holder is arranged at each end of a somewhat longer outer casing.

Title: Improvements in knitting machines
IPC: D04B9/46
Filed: 1935-07-30
Abstract: 462,167. Knitting-machines. TRIGGS, W. W. (Nolde & Horst Co.) July 30, 1935, No. 21592. [Class 74 (ii)] Relates to a circular multifeed knitting-machine capable of knitting seamless hosiery patterned in plating, reverse plating and wrap yarns and presenting, e.g. " colour within colour " effects as shown in Fig. 21. The invention is described as applied to a machine of the " Banner " type and having two feeds. The needles, preferably latch, are divided into two sets with long butts 40 and short butts 41. Below each needle and in the same trick there is a jack 31 provided with numerous butts, located in accordance with the pattern desired, the butts not required being first broken off. The butts left on are actuated by inclined cams 52... 60 mounted in radial slots in cam-supporting blocks 50. There is a main stitch cam set 79 with widening and narrowing picks (not shown) and a second set of stitch cams 88 with associated picks 94, 95. The pick 94 is normally maintained inactive in an unusual position during striping or design patterning. During heel and toe work the additional stitch cam block is pulled out radially so as not to engage needles. The yarn wrap fingers consist of levers of the first order mounted in slots in a head 102 and actuated by cams located at different levels and sliding in apertured blocks 143 ... 145. The cams of the blocks 143, 144 cause variously coloured or otherwise contrasting yarns to be wrapped on the needles at a point in advance of the cam set 79 while block 145 acts similarly with respect to the cam set 88. There may be yarn-changing devices at each feed station. The web-holders each consist of two cooperating parts 278, 280. By acting on a butt 280, the part 280 is pushed radially inwards into a special track. The butts are selected by a pattern wheel mounted on a vertical axis. There are two sets of web-holder cams corresponding to the two stitch cams. The supplementary set is placed out of action during heel and toe knitting by a lever which also takes out the feed finger 91 and puts in the narrowing pick 94. The sinker jacks operated by the control mechanism for reverse plating are held in the same position for two consecutive feeds. Curved pattern-controlled wires or bars 133 ... 135 and 301 mounted in plungers 136, 136a in the latch ring tend when pushed in to prevent the wrap yarns from getting entangled with the web holders &c. The cutter and binder for the yarns 93, 94a consist of a frame 400 fixed to a block 401 and carrying a vertically sliding frame 403. A reciprocating bar 406 slides horizontally in a channelled bar 405 attached to the frame 403 and carrying a vertically movable cutter block 410. The cutting and binding arms 416, 417 are pivoted at 418 to opposite sides of the block 410 and at 427 to the bar 406. The arm 416 has a sharp edge 420 and the arm 417 a rounded edge 421.' There is also a spring-urged auxiliary binding arm 435.

Title: Improvements in electric telephone and like signalling systems and cables therefor
IPC: H01B11/16
Filed: 1919-09-03
Abstract: 153,995. Western Electric Co., (Western Electric Co.). Sept. 3, 1919. Repeating and amplifying systems; induction, preventing.- Comprises means for preventing cross-talk in telephone and like signalling systems, particularly in four-wire repeater systems in which two wires are used for transmission in one direction only and two in the other. The invention consists in segregating electrostatically and magnetically the repeaters, loading- coils, line wires, and leading-in wires used for transmitting in one direction from those used for transmitting in the opposite direction. This arrangement prevents the heavy output current of one repeater from interfering by induction with the feeble input current of a repeater working in the opposite direction. Fig. 1 shows a system in which each pair LW1 is connected to a corresponding pair LE1 through two one-way repeaters R1, R1<SP>1>, arranged in parallel between transformers TE1, TW1. The repeaters R1 R2, R3, working from A to Care segregated at a distance from the repeators R<1>1, R<1>2, R<1>3 working from C to A. The leading-in wires are also segregated in separate cables 12, 13, 14, 15. The cables are wound with metallic tape 27, 29, in order to screen electrostatically the pairs working in one direction (inside the tape) from those working in the opposite direction (outside the tape). The tape may be of magnetic metal so as to act also as a magnetic screen. The pairs in any layer may be segregated into groups by metallic strips 32, 33. Various ways of selecting the pairs to form circuits are described, in which pairs which are members of a four-wire circuit may be separated by other pairs which are either idle or working in two-wire circuits. The strands of the cable may be twins, quads, or eight-wire strands. The loading coils are segregated according to direction in opposite compartments 43 &c., Fig. 6, of a watertight iron casing 40. The coils are threaded on spindles 48, 50 &c. which are positioned by a spider 56, and are magnetically insulated by spacers 57 of magnetic material. Where only one compartment is available, the two groups of coils are separated by a spacer equal in width to one coil, or alternativelv by an ordinary spacer 57 which is grounded.
