Title: Modulating systems for electric wave signalling
IPC: H03C1/58
Filed: 1940-05-24
Abstract: 537,731. Modulating systems. STANDARD TELEPHONES & CABLES, Ltd. May 24, 1940, No. 9181. Convention date, July 15, 1939. [Class 40 (v)] In a modulating system comprising a bridge of contact rectifiers, accidental capacities across the rectifiers are rendered innocuous by connecting series circuits of inductance and capacity across the rectifiers so as to build up one or more circuits having parallel resonance at or about the output frequency. As shown, the system comprises a bridge of four rectifiers, with the input low frequency applied at E across one diagonal, and the carrier source A across the other, the output being taken at the load resistance R. Each rectifier is shunted by a series circuit of capacity C and inductance L which with the accidental capacity across the rectifier form a parallel-resonant circuit tuned to the output frequency, the shunt LC being also designed to present high impedance at the frequency of the input E. Instead of separate circuits across each rectifier, the whole bridge may be shunted by a single circuit (Fig. 5, not shown). The system may be applied to other forms of bridge rectifier circuits (Fig. 6, not shown).

Class 120(2) [Also in Group XXIV] Clutch means for driving a textile spindle or yarn carrier thereon comprises two clutch members on one and the same driven shaft, relatively movable co-axially for engagement and disengagement, one being rotatable with the shaft and the other freely mounted on the shaft and in driving connection with the spindle or yarn carrier; one clutch member is provided with positive-drive coupling teeth or jaws and ,also with a cylindrical outer friction surface, the teeth and friction surface being displaced axially with respect to one another, and the other clutch member is provided with positive-drive coupling teeth or jaws for co-operation with the teeth or jaws of the first member and with. an inner friction surface for co-operation with the friction surface of the first member, the distance between the teeth or jaws of the two coupling members when the clutch is disengaged being greater than the distance between the two friction surfaces such that on engagement the friction surfaces engage first. In the arrangement shown a spindle rail 1 of a textile spinning or twisting machine houses a drive shaft 2 common to all the spindles such as 4 on one side of the machine. The drives to the spindle comprise helical wheels 3 arranged to mesh with the helical thread 5 on the end of the spindle 4. The wheel 3 is rotatably mounted on a sleeve 6 which sleeve can be clamped to the driving shaft 2 by means of ring 9. The wheel 3 is fixedly connected to a bushing 10 by means of a key 11 and a clutch sleeve 12 is non- rotatably mounted on the sleeve 6 by means of a key 13. The sleeve 12 can be moved along the bush 6 by suitable lever mechanism. The clutch sleeve 12 is hollow and is provided with a frictional surface 18 and teeth 19 which engage corresponding friction surfaces provided by rings 15 and teeth 20 on the drive wheel 3. When the sleeve 12 is moved axially the friction surfaces first engage and then the positively engaging teeth 19, 20 engage. When the latter have engaged the ring 15 is locked in a recess portion 17 in the sleeve 12 thus preventing accidental disengagement. The lever 24 for effecting engagement and disengagement of the clutch is provided with an extension 25 which is designed to act as a braking member for engaging the spindle 4 when the lever 24 is moved to disengage the clutch. In further embodiments one part of the clutch is incorporated in the yarn carrier itself while the other portion is either provided on the member movable on the textile spindle or on the whorl driving the said spindle.

Title: Improvements in or relating to the conditioning of textile materials
IPC: D06B1/00
Filed: 1931-03-31
Abstract: Gases and vapours, treating with.-Filaments, yarns, artificial straws or bristles, or other textile materials are subjected in package form to the action of vapours of a conditioning agent generated within the package, which is preferably enclosed in a relatively impervious wrapping of wax paper, parchmentized paper, reconstituted cellulose, or the like, in order to prevent escape of the vapour.  The treatment is particularly applicable to materials made from organic derivatives of cellulose, for example, cellulose esters, such as cellulose acetate, formate, propionate, or butyrate, or cellulose ethers such as methyl, ethyl, or benzyl cellulose.  Natural materials such as silk, cotton, or wool, reconstituted cellulose such as viscose, nitrocellulose, or cuprammonium artificial silk, or mixed materials such as those containing cellulose acetate may also be treated.  The conditioning agent may be water or, for the treatment of materials containing cellulose derivatives, volatile restricted solvents or swelling agents such as, in the case of an acetone-soluble cellulose acetate, ethyl or methyl alcohol or aqueous solutions containing 5-25 per cent of acetone.  The yarn is wound on packages such as cones, pirns, or bottle bobbins, which have a hollow core.  The conditioning liquid may be absorbed in a suitable material such as a sponge, raw cotton, or infusorial earth, and placed within the package, the core of which consisting of cardboard, metals such as aluminium, plastic materials such as celluloid, or phenolaldehyde condensation products, is perforated to allow access of the vapours to the interior of the yarn package.  When the core is of cardboard, it is preferably strengthened by a supporting perforated insert of stronger materials such as those mentioned above.  Relatively non-volatile finishing agents or lubricants may be applied to the yarn before or after the humidifying process.  Examples of such agents are mineral oils, vegetable oils such as castor oil or olive oil, animal oil such as neatsfoot oil, and softening agents such as p  glycol, diethylene glycol, glycerine, or mixtures thereof.

Title: Improvements in and relating to methods of and apparatus for heat treating filaments
IPC: H01K3/02
Filed: 1938-03-30
Abstract: 513,214. Heat-treating filaments. BRITISH THOMSON-HOUSTON CO., Ltd. March 30, 1938, No. 9775. Convention date, March 30, 1937. [Class 72] [Also in Group XI] Metal filaments for incandescent lamps and the like are heat-treated by placing one or more singly in boats of exceedingly small mass and heat-capacity, the boats and filaments being then heated and subsequently cooled in a non-oxidizing atmosphere. In the apparatus shown, the boats 11 holding single filaments are mounted on an endless sprocket chain 10 and are carried by it up into a hollow-walled water-cooled hood 12 into which hydrogen or other inert gas is delivered by a flexible hose 72 to maintain a non-oxidizing atmosphere. The chain is given an intermittent movement by a cam-operated pawl acting on the lower sprocket wheel 14, and comes to rest as each boat 11 is brought opposite to a heating-coil 13. This coil is mounted on the upper ends of rods 30, 31 carried on a slide 33 which is operated by a cam 36 to cause the supporting-rods to move the coil forwardly so that it surrounds the uppermost stationary boat. After the heating period the coil is moved back by the slide, and the chain 10 moves to bring the next boat into position opposite the coil. Cooling of the boats and their contents occurs as they move downwardly in the inert atmosphere in the hood. The boats 11, which are of single or multiple trough form to hold one or more filaments separately, are preferably made from tungsten prepared as described in Specification 155,851, [Class 39 (ii)], and from 0.002 to 0.003 inches thick. They are carried in pins 74 rotatably mounted in blocks 77 secured to the chain 10 and carrying weights 73 which maintain the boats in correct position. The filaments are placed in the boats by hand, the tweezers by which they are handled being guided and supported by a guide or rest 26 mounted on the rods 30, 31 so that it moves forward at the appropriate time and surrounds the end of the boat. After the passage up and down the hood, the boats arrive at an unloading station where they are tipped to discharge the filaments down a chute into a cup. The heating coil 13 is preferably of tungsten and is supported intermediately of its ends by wires 79, 80. A shield 89, apertured for the passage of the coil, protects the chain 10 and other parts from the radiated heat. The filaments are raised to a temperature of from 1900 to 2300C., the heating period being preferably less than 30 seconds and in some cases only 5 seconds.
