IPC: D01H1/40
Filed: 1955-08-24
Abstract: 780,415. Winding thread. BRITISH NYLON SPINNERS, Ltd. Aug. 13, 1956 [Aug. 24, 1955], No. 24304/55. Class 120(2) Apparatus for winding thread comprises a ring and traveller traversing mechanism, a spindle extending upwardly therethrough and carrying both a main thread receiving tube and an auxiliary tube or disc around the base portion of the main tube, the auxiliary tube or disc having a thread engaging slot or member in or on its periphery and being adapted to be driven by friction in company with the main tube or to be held stationary by clamping means relative to the main tube, and a waste removal device positioned relative to the auxiliary tube or disc such that, on rotation of the latter, thread is wound up on the main tube above said tube or disc and as a transfer tail, below the thead engaging slot or member of said tube or disc. In the arrangement shown the yarn 1 is led through the traveller 3 of the traversing ring 5 and thence to a slot 7 in the top rim of an auxiliary tube 9 which is held against rotation by a pivoted catch 11 situated on the spindle rail and rests on top of the spindle whorl 13 and is then led into the mouth of a suction tube 15. When the spindle 17 is started the main tube 19 rotates therewith and when yarn is being produced in the fully processed form a catch 17 is removed from engagement with the tube 9 which latter steadily attains the speed of the main tube 19 and in so doing wraps a bight of yarn around the main tube above it and another around itself below the slot 7. The yarn between the suction tube and the auxiliary tube is cut when sufficient turns have been taken round the latter to make a satisfactory " transfer tail" whilst the yarn being forwarded to the winding unit winds up directly from the traveller on to the main tube. Specifications 643,625, 780,414 and 780,416 are referred to.

Title: Improvements relating to electric cable systems having means for locating electric faults therein
IPC: H01B7/32
Filed: 1945-09-20
Abstract: 598,936. Indicating faults; cable systems. OKONITE-CALLENDER CABLE CO., Inc. Sept. 20, 1945, No. 24378. Convention date, Sept. 21, 1944. [Classes 36 and 37] In a cable system in which an insulated conductor is surrounded by fluid such as oil, fault locating means are provided comprising an indicating device which is operated by an impulse of mechanical pressure set up as the result of a fault and remains in its operated position after the impulse has ceased. Insulated conductors 2 are drawn into a steel pipe-line 4 which is maintained full of insulating fluid under superatmospheric pressure, e.g. 200 lbs. per sq. in. The pipe-line is provided at intervals with joints 6 dividing the system into short sections. Two tubes 8 are in commtmication with the interior of each section of the pipe-line and each tube is provided with a diaphragm 10 capable of withstanding the normal oil pressure. If an electric fault occurs in one of the sections of the pipe-line, the diaphragm in one or in each of the tubes 8 connected to that section is either deflected or ruptured by the pressure impulse set up in the oil. At the upper end of each tube 8 is a pressure gauge 12 of the maximum indicating type, which normally indicates zero. After a diaphragm has been deflected or ruptured, the corresponding gauge indicates pressure, showing that an electric fault has occurred in the corresponding section. The gauges 12 are located where they are visible at all times, or they may be placed beneath the ground, but readily accessible for inspection. Instead of pressure gauges those portions of the tubes 8 above the diaphragms may be provided with transparent windows through which oil passing through a broken diaphragm may be seen. Alternatively, the gauges may be replaced by petcocks. Oil flowing out of one of the petcocks when opened indicates rupture of the diaphragm.

Title: Manufacture of para-cymene
Filed: 1919-10-06
Abstract: p-Cymene is prepared from pine-needle oil fractions boiling at about 160 DEG  C. by chlorination followed by steam-distillation of the product, in the manner described in the parent Specification. The yield of cymene is increased by heating the raw material with an inorganic or organic acid or acid salt, removing the reagent, fractionally distilling the product, and using the fraction boiling at 175 DEG  C. for chlorination.

Title: Improvements in and relating to electric motor control apparatus
IPC: H02P7/292

Abstract: 402,208. Control of D.C. motors. BAILEY METER CO., 1050, Ivanhoe Road, Cleveland, Ohio, U.S.A.-(Assignees of Ryder, J. D.; 11448, Euclid Avenue, Cleveland, Ohio, U.S.A.) Sept. 2, 1932, No. 24508. Convention date, Sept. 3, 1931. [Class 38 (iii).] A separately excited motor has its armature supplied with direct-current for running, and is stopped by substituting alternating-current for the direct-current. The invention is described in connection with a fluid pressure main. taining system. Upon deviation of the pressure in a pipe 1, a Bourdon tube 3 is actuated to open one or other of switches 24, 25, to interrupt the discharge through a corresponding electron tube 10 or 11, so that pulsating direct-current is applied to the armature of a valve-operating motor 6. The motor is stopped when the switches 24, 25 are operated to allow both tubes 10 and 11 to conduct and supply alternating- current to the motor armature, "plugging" being effected during alternate half-waves. The switches 24, 25, may be hand controlled and arranged to close instead of open, for operation of the motor. In a further arrangement, the motor armature is energised with continuous, instead of pulsating current. The speed of the motor may be varied by arranging the switches 24, 25 to move a choke, the core of which may be shaped, or a graduated resistance, whereby a phase shift between the grids and anodes of the tubes 10, 11, is obtained. The Specification as open to inspection under Sect. 91 comprises arrangements in which the tubes 10, 11, are normally non-conducting. This subject-matter does not appear in the Specification as accepted.

Abstract: 259,752. Goodhart, G. C. Oct. 5, 1925. Foot deformity, treating. -An appliance for the correction of inward or excessive outward turning of the foot consists of a band A of webbing &c. wound spirally round each leg. The two bands may be connected at their upper ends by a length of elastic material which passes over or is attached to a belt C, braces, or other part of the garments, or the bands may terminate in separate pieces of elastic material which are attached individually to a belt &c. The lower ends of the bands may be formed as loops which pass round the insteps of the boots or the bands may be attached to the boots in any other way. Elastic insertions may be placed in the bands at any point or the bands may be made entirely of elastic material or springs may be used, instead of elastic insertions. Straps and buckles &c. may be provided for adjusting the tension. To prevent pressure on the legs the lower ends of the bands may be wound round a leather anklet or legging as shown in Fig. 3. The band A is sewn to the boot and after passing around the legging D passes under a staple G. An elastic band B forms a continuation of the band A and is fastened by a clip H to the clothing. The anklet or legging may be made in one with the boot.

Sept. 3, 1931, No. 24781. Convention date, Sept. 4, 1930. [Class 83 (iv).] In metallic or carbon are welding the parts are enclosed in a chamber having a wall of fluxing material, which is partly consumed by the heat of the arc to form a protective medium over the fused metal. An arched chamber 3 may be formed by a folded sheet or several sheets of paper, the edges of which are secured by clamps 4, 5, 6 to the work parts 1, 2, one end of the chamber being preferably closed. The parts may rest on a table or bed 7 having a chill insert 11. The paper is in part burnt by the heat of the arc or by contact with the electrode 9 to furnish an atmosphere of carbon monoxide and carbon dioxide. The paper may be loaded with kaolin or clay or saturated with sodium or potassium silicate so that it does not burn readily and also deposits flux on the weld. The chamber may also consist of asbestos, impregnated cloth, or thin walled glass, in the form of an inverted slitted troughlike member &c., or may consist of a frame with a covering of paper secured thereto. The top of the member may be slit or perforated, or may be of reduced section so that the electrode may pass through it. A paper shield may be slit by charring thereof during the progress of the welding operation. Any carbon precipitated on the fused metal reduces oxygen dissolved in the metal with the liberation of heat and also increases the carbon content thereof.
