Title: Improved process and means for the refining of glass and the like
IPC: C03B5/225
Filed: 1930-12-19
Abstract: 359,801. Glass manufacture. FOURLINNIE, A., 135, Rue Daubresse Mauviez, Mons-en-Baroeul, Nord, France. Dec. 19, 1930, No. 38306. Convention date, Jan. 2. [Class 56.] Purification of metal.-A method of refining glass, or other vitreous material, consists in raising it to a temperature which is lower than the usual refining temperature, and then submitting it to the action of centrifugal force in order to expel the enclosed gas bubbles. A device for carrying out the process comprises a conical metal vessel a which is supported on rollers c within a casing d fitted with a cover j. The vessel a has a central chamber e with an axial opening el, and ducts f lead from the chamber to a central duct f and thence to a discharge pipe g. The vessel is heated by hot gases which enter the cover j through an opening i and pass through passages h in the vessel a to an opening k in the casing. In use, the vessel a is rotated about its vertical axis by driving one of the rollers c, and the glass, which has been melted in a furnace of the usual type, is poured into the vessel through an opening l in the cover j. While the glass is in the chamber e, centrifugal force causes the enclosed gas bubbles to escape and the refined glass passes continuously through the ducts f<1>,f<1>, g into a receptacle from which it is worked out as desired.

Filed: 1975-09-19
Abstract: 1515578 Measuring temperature electrically NATIONAL SEMICONDUCTOR CORP 19 Sept 1975 [23 Sept 1974] 38621/75 Heading G1N [Also in Division H3] The outputs from two transistors 45, 46, Fig. 1, operated at different current densities are fed via a differential amplifier 22 to a transistor 42 whose output determines the voltage between terminals 43, 44 and therefore the bias voltages for the bases of the transistors. When the ambient temperature changes, the collector currents of transistors 45, 46 change by different amounts to alter the input and output of amplifiers 22, 42 until a new balance condition is achieved and the supply voltage across terminals 43, 44 is proportional to the new temperature. By appropriate choice of resistors 30, 32, 34 the supply voltage is made proportional to a desired temperature scale. The two emitters of transistor 46 have equal areas, whereas the emitters of transistor 45 have unequal areas, and the ratio of the current densities of transistors 45, 46 is established by adjustment of potentiometer 56 in the emitter-ground connections. The feed resistors 52, 54 may be replaced by transistors Fig. 2, (not shown). Reference has been directed by the Comptroller to Specification 1469984.

Title: Work transfer mechanism for a multiple stage press
IPC: B21D43/05
Filed: 1959-11-16
Abstract: 893,199. Cupping. SCHULER A.G., L. Nov. 16, 1959 [June 22, 1959], No. 38729/59. Class 83 (4). A multiple station press is provided with a duct to receive workpieces leaving a deep drawing tool from which they are returned to a transfer plane common to all the stations, said duct being located directly adjacent to the tool and is associated with a device for returning the workpieces to the transfer plane. In an embodiment the cupping punch 4 carried by the press ram 3 co-operates with a die 7 fixed to a mounting 5. Beneath the die 7 is a duct 9 leading away from the die and terminating in a vertical bore 10 within which reciprocates a bolt 11 supported on a pneumatic, spring or rubber mounted die cushion 23. A spring- loaded slide 12 actuated by a rod 16 attached to the ram and having a wedge-shaped end 17 is reciprocable in the duct. Pressure pins 21 on the ram engage pins 22 attached to the die cushion. In operation, a pre-drawn workpiece is transferred from tool station II to the tool station III where it is deep drawn by the punch 4 and die 7. As the punch and ram moves downwardly, the slide 12 is retracted by the rod 16 assisted by the workpiece 20 on the punch engaging a sloping surface 19 on the slide. On the upward movement of the ram the workpiece is released from the punch by a stripper 8 leaving the workpiece in the duct where it is moved away from the die bore by the return movement of the slide 12. On each downward movement of the punch a new workpiece is brought into the duct and eventually the first workpiece is pushed into alignment with the bore 10, whereupon it is engaged by the bolt 11 and lifted up to the transfer plane for onward transmission by a gripper on the press to the next tool station for further treatment. Alternatively, the workpieces are advanced in the duct either by a reciprocating member driven by a part connected to the ram by compressed air or by a periodically driven turntable. Also the bolt may be controlled independently of the die cushion and operated by a compressed air cylinder or spring drive mechanism.

Abstract: 1,186,039. Feeding webs. A. V. ALEXEFF. 25 Aug., 1967 [1 Sept., 1966], No. 39179/67. Heading B8R. Web guiding apparatus of the type comprising mutually diverging stretching rollers is characterized by one guide roller on each side of the web being angularly adjustable whereby an end of the guide roller which is nearest the centre line of the web remains substantially stationary while permitting movement of the outer end of the guide roller toward and away from the web. As shown, the middle roller 13 of three is rotatably mounted on a cantilevered shaft 12 attached to a support arm 16 pivotally supported by a yoke 17. The axis of the pivot pin 18 is in alignment with the inner end 19 of the roller 13. Pivoting of the support arm 16 about the pin 18 effectively pivots the roller 13 about its end 19 with respect to the plane of the web. The edge of the web is threaded between the three rollers 8, 13, and 9. The other edge of the web is similarly threaded (Fig. 1). An edge detector (30) senses deviations of the web, and controls through a fluid pressure system and actuator (22), the reciprocable piston rod 24 of which is connected via a bell-crank linkage to the pivoted support 16 of the roller 13.

Abstract: 1,234,942. Electric tests. BRITISH INSULATED CALLENDER'S CABLES Ltd. Aug.23, 1968 [Aug.25, 1967], No.39280/67. Heading G1U. Faults in the insulation of an electric cable 10, Fig. 1, screened with a semi-conductive sheath are detected by passing the cable lengthwise through an elongate insulating vessel 1 filled with an insulating liquid 4, containers 5, 6 filled with an earthed conductive liquid 7 being provided at each end of the vessel to earth the screen. The cable conductor is earthed and a high voltage is applied to annular electrodes 2, 3, disposed near the centre of the vessel 1, through resistors R1, R2, Fig.2. The electrodes are also connected through respective capacitors Cb1, Cb2 to the ends of a transformer primary winding L3, L4 whose centre tap is earthed. Resistance and capacitance are connected in parallel with each half of this winding and adjusted so that the circuit is normally balanced and no voltage induced in the secondary winding L1. A void in the insulation of the cable will initiate electric discharges as that portion of the cable passes through each electrode in turn, and this will unbalance the circuit and cause an indication to be given on an indicator 16 connected through an amplifier to the secondary winding. Alternatively the balanced circuit described in Specification 1, 071, 050 may be used. The vessel 1, Fig. 1, may be a plastics tube provided at each end with a liquid-tight semi-conductive seal 11, 12, made, for example, of a conductivelyloaded elastomer. The insulating liquid 4 may be deionized water and the conductive liquid 7 mercury, sodium chloride solution or tap water. A chain earth electrode may supplement the liquid earth electrodes 7.

Title: Improvements in picking mechanism for looms
IPC: D03D49/46
Filed: 1929-12-23
Abstract: 344,568. Loom picking mechanism. BATTY, G. F., Woodholme, Harlow Oval, Harrogate, Yorkshire. Dec. 23, 1929, No. 39329. [Class 142 (iii).] Spring picking motions; checking shuttles and pickers; pickers and connections.-In a spring- picking; motion the kinetic energy from the flying shuttle is absorbed by resilient buffer means which has further energy imparted to it by a second positive movement of the shuttle after it enters the shuttle box, the potential energy thus provided being subsequently released to propel the shuttle in the reverse direction. A picker block 11, Fig. 1, slidably mounted on guides 12, 13, is moved, by the impact of the shuttle 29, against the influence of a spring 14 and into contact with a second block 33, causing the latter to slide on its supporting guide 12 against the action of a spring 32. As tension is applied to the spring 32, a bell-crank lever 30, connected thereto, is rocked about its fulcrum 31 to. apply a brake 28 to the shuttle, the length of the supporting arm 30 plus the thickness of the brake and the shuttle being greater than the shortest distance between the fulcrum 31 and the guide against which the shuttle is pressed. The fulcrum pin 31 is carried by a link 34 controlled by a spring 36 and a cam 58 acting through levers 56, 41, the rod 40, and a bellcrank lever 37, a clockwise movement of the latter about its pivot 38 allowing the brake to fall into operative position. A member 23 mounted on a spring arm 22, Fig. 3, and adapted to slide on horizontalguides is brought into engagement with the shuttle by means of a fixed roller 61 as its roller 45 is moved outwards by the free end of a drive lever 43. The latter member is pivoted at 44 and is operated against spring action by the cam 58, the lever 41 being connected by a tie 46 to a bell-crank lever 47 having a roller 48 adapted to engage with a roller 49 caused by a spring- controlled plate 50 pivotally mounted on the lever 43. When tension has been applied to the springs 14 and 32 by the entry of the shuttle into the box and the subsequent movement of the engagement member 23, the plate 50 engages a fixed pin 62, and the continued action of the cam 58 causes the roller 49 to over-ride the roller 48 whereupon the member 23 is withdrawn from the path of the shuttle. At the same time, the action of the cam 58 gives a clockwise movement to the lever 34 to release the brake, thereby releasing the tension on the springs and allowing the shuttle to be shot across the shed.

Abstract: 822,254. Automatic control systems for oscillators. COLLINS RADIO CO. Dec. 30, 1957 [April 9, 1957], No. 40321/57. Class 38 (4). [Also in Group XL (c)] To form a wobbulator, a sawtooth voltage is applied to a reactance valve associated with the tuned circuit of an oscillator which is provided with automatic gain control to maintain amplitude of oscillation constant. In Fig. 1, a tuned circuit 15 comprising a plug-in coil and variable capacities is connected in the anode circuit of a pentode valve amplifier 22 and oscillation is produced by positive feedback from the anode circuit to the grid circuit of amplifier 22 through a pentode valve amplifier 11, a diode squaring circuit 16, and a triode valve cathode follower 17. The frequency of the oscillator is continuously swept over a band by applying a sawtooth voltage at terminal 6 to vary the reactance of a valve 7 connected to tuned circuit 15. Reactance valve 7 is inductive by virtue of feedback through a condenser 12 and the width of the swpet band is adjustable by a potentiometer 8. The amplitude of oscillation is maintained constant during the sweep by applying the oscillator voltage through a triode valve cathode follower 19 and a biased clipper circuit 18 to control the gain of cathode follower 17. The constant amplitude output is obtained at terminal 21 from the output of cathode follower 19 and a lower, adjustable, voltage output is obtained at terminal 25 through a potentiometer 23 and a further triode valve cathode follower 24.
