Title: Improvements in loose leaf binders
IPC: B42F13/00
Filed: 1920-06-30
Abstract: 164,972. James, F. June 30, 1920. Covers; fastenings; locking-followers.-In looselea.f binders of the type in which one clamping- bar is provided with ball-clutches for engagement with binding-posts carried by the other clamping- bar, and with means for disengaging the balls from the post when the upper bar is to be removed, these means comprise sliding cams acting on the balls, preferably in the form of flat strips mounted in slots in the collars of the ball clutches. In the form shown, the spring-pressed balls 5, mounted in inclined recesses in the collars 1 and acting on the posts 3 through tapering slots 6, are raised away from the posts by the cams 9 formed on a single flat strip 10 mounted in slots in the collars 1 and operated by a bent end 13 of the strip accessible by means of a notch in the end of the bar 8. The bar 8 can thus be thrust down on to the papers, but cannot be raised until the balls are disengaged from the posts by the strip 10.

Abstract: 356,802. Electrolysis. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Materiel Telephonique ; 46, Avenue de Breteuil, Paris.) June 12, 1930, No. 18029. [Class 41.] Alkali metals, obtaining.-A photo-electric cathode is formed by introducing an alkali metal such as potassium or sodium into the interior of the wall of the cell by electrolysis and liberating the metal on to the interior surface of the wall by reverse electrolysis. Preferably a glass envelope containing molten potassium nitrite is partly immersed in a bath of molten potassium nitrite and current is passed in a direction such that potassium ions pass into the glass. The envelope is then cleaned, a filament carrying a piece of magnesium is introduced, and the envelope is evacuated. The envelope is immersed again in the bath and the filament is heated to produce a deposit of magnesium on the cool part of the envelope. Current is passed in the reverse direction with the filament and bath as electrodes so that the potassium ions in the glass are deposited on the magnesium layer ; or evaporation and deposition of magnesium and reverse electrolysis may be carried out at the same time.

Abstract: 627,160. Systems depending on variable-speed generators ; electric coils. FORD MOTOR CO., Ltd. July 10, 1947, No. 18345. Convention date, July 26, 1946. [Classes 35 and 38 (iv)] [Also in Group XXXVII] A generator used for charging a battery is provided with a voltage control switch, a current control switch and a battery-connecting switch all mounted on the same base (see Group XXXVII). The voltage control switch inserts a field regulating resistance in the field circuit of the generator when the voltage becomes too high, the current control switch inserts the same resistance when the current becomes too high and the battery-connecting switch permits passage of current from generator to battery, but not vice versa. The voltage control coil and the shunt coil of the batteryconnecting switch are compensated for temperature variation by making part of the coil of a copper-nickel alloy with a negative or zero coefficient of resistance.
Patent GB-569714-A (GB)
Title: Improvements in looper-thread controlling mechanisms for sewing machines
IPC: D05B57/02
Filed: 1943-11-05
Abstract: 569,714. Sewing- machines. SINGER MANUFACTURING CO. Nov. 5, 1943, No. 18385. Convention date, April 30. [Class 112] In a double-loop stitch sewing machine a single adjusting means is provided for the work feed and the under thread pull-off. The feedbar 53, receives its rising and falling movements from an eccentric 55 on the main shaft 4 and its to-and-fro movement from an adjustable feed eccentric 60 mounted on a slide-block 61 in a collar 62 fixed on the shaft 4. An adjusting screw 66, when rotated; moves the block 61 to vary the eccentricity of 60. A looper-thread pull-off member 68 is secured to the slide block 61 and consequently its effective radial length is varied when the feed eccentric is adjusted. It is slotted at its free end to embrace a thread stripper-finger 69, mounted on a carrier plate 70. Opposed spring members 75, 76 act as thread nippers which are actuated by a cam 78 on the shaft 4, which acts through a slot in the plate 70. A looper take-up such as described in Specification 425,524, comprises a cam 79 projecting through a slot in the plate 70, and embraced by a U-shaped wire loop 81 acting as a thread-detainer. Thread guides 83 are provided. Thread passes from a supply, eyelet 84, below the work-support to the nearest thread-eye 74 and then through a slot 72 in the stripper-finger 69. The thread then passes through a second thread-eye 74, between nipper springs 75, 76, through the first guide 83, beneath the detainer into the second guide 83 and so to the looper. When the looper 19 moves forward in entering and seizing the needle-thread loops, the nipper springs 75, 76, are separated, with no drag on the thread. This permits free movement of the thread, as required by the looper, from a bight of thread previously drawn off supply by the pull-off finger 68. During the backward movement of the looper springs 75, 76 grip the thread, and the slack thread from the looper is taken up by rotation of the cam 79. During this time the finger 68 engages the thread and pulls off from the supply, the required length of looper thread for use in the next stitch. The length of stitch, and the travel of the feed-dog, are simultaneously adjusted by rotation of the screw 66. The thread-receiving slot 72 has an upward inclination at the rear end, to facilitate casting off the thread should the machine, and the arm 68, bo inadvertently reversed.

Abstract: 399,290. Coin-freed article-delivery apparatus. COATS, Ltd., J. & P., 155, St. Vincent Street, Glasgow, and WRIGHT, C., The Hollies, Mill Hill, Edgware, Middlesex. June 30, 1932, No. 18460. [Class 27.] A coin-freed apparatus for displaying and delivering reels of thread comprises a cabinet 7, Fig. 1, the front of which has a series of glazed display apertures 9 arranged in horizontal and vertical rows. Extending from each aperture is a downwardly and rearwardly inclined reel shoot 12, beside and parallel to which is disposed an associated coin shoot 13 leading from a coin slot 11. The coin and reel shoots of each vertical row feed into common coin and reel shoots which lead to a common coin box and to a reel delivery tray 14 respectively. The top reel 10 in each reel shoot is retained in front of the display aperture, as long as there is another reel in the shoot, by the bent end 33 of a rod 31, Fig. 3, pivoted at 32 on the underside of the shoot, the lower end 34 of the rod being normally depressed by the weight of the reels. When the last but one reel is delivered, the end 33 sinks and allows the displayed reel to roll down the shoot for delivery. The reels are delivered one at a time by a varied wheel 24 mounted on a spindle 22a which has a ratchet wheel 22. The ratchet wheel is controlled by a pawl 17 which is tripped by a coin passing down the coin shoot. Coins, testing.-The inserted coins pass through the shoot 13 to a balance 15 which tips, if they are of proper weight, and allows them to roll down to trip the pawl 17. The balance may be adjusted so that several coins are necessary to secure delivery. Undersized coins fall out through an opening 28 in the shoot 13 and do not pass to the balance 15.
