Title: Improvements in or relating to yarn or like winding machines
IPC: B65H54/30
Filed: 1934-12-15
Abstract: 437,556. Winding yarns. UNIVERSAL WINDING CO., 95, South Street, Boston, U.S.A. Dec. 15, 1934, No. 36040. Convention date, April 27. [Class 120 (ii)] In a yarn or the like winding-machine, the yarn is traversed longitudinally of the bobbin &c. which is carried by a holder moved progressively endwise as the winding proceeds by a bell-crank lever, one arm of which engages the periphery of the wound yarn package and the other arm engages the holder to move it endwise. As shown the yarn is wound on a bobbin B, Fig. 2, having a conical base h and the wound yarn is engaged by a polished roller 85 carried by anti-friction bearings in a yoke 84 freely pivoted in one arm 71 of the bell-crank lever 71, 72, the other arm 72 of the lever carrying a bowl engaging the groove 50 between a pair of collars 49 on the holder or tube 40 carrying the bobbin B. The arm 71 is pivoted by a stud 82 to a hub 73 of the arm 72 so that the arm 71 may be swung upwards to take the roller 85 out of the way of the bobbin for doffing the wound package or placing a fresh bobbin on the tube 40 ; a lug 83 on the arm 71 engages the hub 73 in the operative and inoperative positions of the roller 85. The hub 73 of the bell-crank lever is pivoted in the downwardly-extending portion 68, Fig. 5, of a bracket 64 by a shaft 75 and is swung to maintain the roller 85 in contact with the yarn being wound by a spring 78 coiled around the shaft 75 with one end engaging the hub and the other a collar 76 adjustably fixed to the shaft to control the tension of the spring; the brackets 64 for a number of winding heads are fixed to the longitudinal tie rods 62 connecting the heads. The conical bobbin B is positioned on the tube 40 by a collar 51 adjustable on the tube and engaging the inside of the conical base h and the bobbin is held on the tube by a spring 54 having bowed portions 55 engaging the bobbin and limbs lying in grooves in the tube, the limbs being connected by a portion 56 lying in a diametral slot formed in the end of the tube. At the start of the winding the innermost collar 49 of the tube abuts against the usual brake wheel 48 fixed to the winding spindle and the outward movement of the tube is limited by a pin 47, fixed across the end of the spindle 41, engaging the end of a counterbore in the tube which is rotated by the spindle through keys 45 in the spindle engaging a key-way in the tube. The traversing guide 25 is bevelled at the side 24 so that it may move into proximity to the conical base h of the bobbin.

Title: Improvements in hat-blocking machines
IPC: A42C1/04
Filed: 1946-12-05
Abstract: 626,352. Hat-blocking machines. VILLERS & CIE, L. Dec. 5, 1946, No. 36079. Convention date, Aug. 23. [Class 63] A hat-blocking machine of the type comprising male and female matrices the co-operating surfaces of which are adapted to shape a piece of material into a crown, and having means for applying heat to the material, is characterised in that the male matrix 8 is movably mounted on the machine and forms the opening for the head by engagement with a member 6, to which the edge of the material 10 is secured, when the two matrices 8 and 9 with the material gripped between them move into the position shown in dotted lines. The male matrix 8 is carried on the flange 4 of a tube 3 which slides in a tube 2 fixed on the base of the machine, a spring 5 being interposed between the flange 4 and the base. A sleeve 6 attached to the base, the top of which is oval like the shape of the head, has a peripheral groove 7 in which the felt or fabric 10 for the hat is fixed by a band, after having been placed over the male matrix 8. The female matrix 9 is placed thereover and vertical pressure applied which compresses the spring 5 and causes the flange 4 to move downwards into contact with the top of the sleeve 6, the material 10 coming into contact with the interior edge of the male matrix 8 to form the head opening. After heating, the hat may be removed by freeing the band by which it is fixed to the sleeve.

Title: Improvements in or relating to circuit arrangements for obtaining a stabilized supply voltage
IPC: H02M7/155
Filed: 1963-09-13
Abstract: 980,377. Voltage stabilizers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 13,1963 [Sept.17, 1962], No. 36154/63. Heading G3X. [Also in Divisions H2 and H3] A load 12 is supplied with a stabilized direct voltage from an A.C. source 1 by way of a semiconductor controlled rectifier 5, an RC smoothing circuit 7, 8, 9 and the collector-emitter path of a transistor 10 the base of which is connected to a constant voltage element 11. A phase shift network supplying the firing signal for the controlled rectifier 5 comprises a transformer 6, a capacitor 4and a negative temperature coefficient resistor 2 which is thermally associated with the transistor 10. The arrangement is such that the resistance of resistor 2 decreases as the transistor heats up whereby the rectifier 5 is rendered conductive for a smaller part of each cycle. Thus, the average voltage across capacitor 7 decreases with a consequent decrease in the dissipation of transistor 10 which is thereby protected against overloads. The resistor 2 is preferably constructed as a disc connected to the transistor 10. An inductor may replace the capacitor 4 (Fig. 2, not shown) in which case the transformer 6 can be omitted. The circuit may be modified to use a temperature sensitive resistor having a positive temperature coefficient (Fig. 3, not shown). The controlled rectifier may be a thyratron, and the temperature sensitive element in the phase shifting network may be a capacitor.

Filed: 1963-09-16
Abstract: 1,071,333. Making gramophone records. DECCA Ltd. Aug. 26, 1964 [Sept. 16, 1963], No. 36295/63. Heading B5A. An embossing press for making gramophone records from pre-formed discs 11, i.e. discs requiring only embossing of the sound track thereon to complete manufacture, comprises hydraulic rams 15, 16 which carry sound track producing die plates, the ram 15 having a long stroke, e.g. 6 inches, compared with that of ram 16, e.g. <SP>5</SP>/ 16  inch, and being capable of remaining stationary when subjected to the maximum force exertable by ram 16, e.g. 150 tons. Rams 15, 16 carry pistons 22, 23, respectively, and each piston in turn carries a platen 21 guided by rods 24. Mounted on each platen 21 is a die-plate assembly 25, Fig. 2 (not shown), carrying annular die plates 26 and thermostatically controlled heating coils 27. In operation a disc falls vertically from a heating station where the central portion of the disc is heated, see Specification 1,071,334, and a cleaning station, see Specification 1,071,332, between nylon grooves 42 to be held in approximate position within a disc slot 41 by catch arms 43. A locating device 31, described in Specification 1,071,335, accurately positions and supports the disc and causes retraction of catch arms 43 which in turn cause movement of ram 16, ram 15 being already fully extended. After embossing, ram 16 and the locating device 31 are retracted and the disc is prised off the die plates by spring ejectors 44 to fall down a nylon tracked shoot (not shown) to a labelling station. Ram 15 is retracted when, for example, the die plates 26 are to be changed. Also a safety guard 45, Fig. 1, must be moved to gain access to disc slot 41, the movement causing breaks in the ram actuating circuits. Photo-electric detectors 46 are provided immediately above and below die assemblies 25 and inhibit operation of ram 16 unless discs pass both detectors after an operation of the ram.

Title: Improvements in or relating to apparatus for winding filamentary materials
Inventor: HUNTER GEORGE WILLIAM
IPC: H01J19/00
Filed: 1958-11-13
Abstract: 865,022. Tension regulators. STANDARD TELEPHONES & CABLES Ltd. Nov. 13, 1958, No. 36490/58. Class 120(2). Constant tension of wire or yarn being wound on a mandrel is maintained by pneumatic means which retards the rotation of the supply reel under control of tension variations of the wire or yarn. The supply reel 2 is mounted on a spindle 3 with a pneumatic brake comprising an air jet from a supply line 7 directed on to a vaned wheel 4 fixed to the spindle 3. The wire passes over a pulley 49 mounted on a pivoted arm 42 which is biased by a weight 45 and adjustable tension spring 46. A palette 43 rests on the arm 42 so that it oscillates with variations in wire tension to control the air flow from a jet 44 thereby varying the pressure applied to a diaphragm 332. A needle 39 attached to the diaphragm 332 controls the flow of air of a second pneumatic system between chambers 32 and 33 by moving into or out of engagement with a conical seating 38, and thus regulates the jet directed on to the vanes 4. An increase of wire tension raises the palette 43 so that the needle 39 engages the seating 38 to decrease the braking effect of the jet issuing from the supply line 7. A friction clutch, which is contained in a casing 9, prevents the jet from the supply line 7 from rotating the spindle 3 in a reverse-direction if the wire breaks.

Title: Improved manufacture of trichlorethylene
IPC: C07C17/25
Filed: 1928-12-14
Abstract: 302,321. Consortium fur Elektrochemische Industrie Ges. Dec. 14, 1927, [Convention date]. Trichlorethylene is obtained from acetylene tetrachloride at temperatures about 500‹ C., by passage of the vapour at such a high speed over large surfaces in a suitable reaction chamber that only part of the vapour is converted into trichlorethylene, the formation of by-products thus being avoided. The speed depends also upon the form of furnace, temperature, nature of catalyst &c. The heat contained in the unchanged vapour may be recovered by heat exchangers, and the incoming vapour may be preheated, even up to the reaction temperature. A cyclical process may be used, the trichlorethylene being separated by fractional condensation. Suitable contacts are pumice-stone, wood charcoal, active carbon and silica gel., while metallic oxides and salts may be employed as catalysts. Specification 23780/06 is referred to.
