Title: Improvements in carding machines for textile fibres
IPC: D01G15/20
Filed: 1961-01-20
Abstract: 973,086. Carding-engines. F. REITERER, L. WINDISCH, and J. NIFENECKER. Jan. 20, 1961 [Jan.21, 1960], No. 2460/61. Heading DiN. A carding machine has means for clearing the licker-in of the fibres that remain upon it after the transfer of fibres to the swift, the clearing means serving also to convey the fibres to the feed lap in advance of the feed roller. In one arrangement, the draught of air generated by the licker-in escapes through a channel 10 in casing 9 to be discharged through a perforated rotary roller 11. Fibres are cleared from the licker-in by the air-stream and transmitted to the feed roller 2 to be presented again to the licker-in in association with the lap 1. The perforated roller 11 may have a fixed internal air deflector and the casing 12 may partially cover the roller 11. With the object of separating short fibres, the casing 9 may be perforated at 22, Fig. 7, and a suction chamber 23 provided. Instead of perforating the casing 9, a gap may be left between the adjacent edges of the casing 9 and the rear plate 8, the gap communicating with a suction chamber (Fig. 8 not shown). In another embodiment, the roller 11 may be replaced by an imperforate grooved roller over which a suction hood is arranged (Fig.5 not shown).

Title: Improvements in or relating to fault localizing apparatus
IPC: H04M3/08
Filed: 1955-01-27
Abstract: 790,313. Protective arrangements. TELEFONAKTIEBOLAGET L. M. ERICSSON. Jan. 27, 1955 [Jan. 27, 1954], No. 2551/55. Class 38 (5). [Also in Group XL (c)] In an arrangement for indicating and locating a fault in one or more units within a group of such units, e.g. electron tubes 1 ... 4, each unit is arranged to apply a " blocking " potential to a rectifier 15 ... 45 in opposition to a reference potential provided by a source 27 connected in series with the secondary winding of a transformer 26 controlling an indicating device 28. Should a fault cause a fall in any of the blocking potentials, the corresponding rectifier 15 ... 45 becomes conductive and the impedance presented to the secondary winding becomes low, resulting in the operation of the indicating device 28. Then under the control of the device 28, or manually, a selector 16 is operated to disconnect the secondary winding from the common rectifier connection L2 and to connect it in turn through a rectifier 20 to each unit. When the device 28 indicates the faulty unit, the selector stops, or is stopped, and a changeover switch 19 may then be operated so that the voltage of the faulty unit may be measured at 18, the switch 19 disconnecting the source 27 and earthing the rectifiers 15 ... 45. Specification 764,096 is referred to. Reference has been directed by the Comptroller to Specification 612,362, [Group XL (c)].

Title: Double grip or holding tool
IPC: B25B27/12
Filed: 1932-01-29
Abstract: 388,552. Pliers. TONDEUR, R., 25, Denbigh Terrace, Notting Hill, and BOWDEN (ENGINEERS), Ltd. (formerly BOWDEN WIRE, Ltd.), Victoria Road, Willesden Junction, both in London. Jan. 29, 1932, No. 2720. [Class 61 (ii).] In a double-grip or holding tool for opening or closing curved objects, e.g. a piston ring, has the pair of grips so coupled to the actuating means that the grips are first caused to grasp the object and then caused to recede or approach one another in an arcuate path having substantially the same curvature as the object. The object-engaging portions of the grips lie at a substantial distance from the general plane of the tool. A hand tool, Fig. 1, has handles 1, 2 and arms 4, 5 all mounted on a common pivot 3. Grips 7, 8 are mounted in slots 6 in the arms, being adjustable with respect to the pivot 3. The grips are perpendicular to the plane of the arms 4, 5, and each grip comprises a fixed jaw 9, Fig. 2, and a jaw 10 slidably mounted therein, the jaws being maintained in open position by a spring 12. The jaws 10 are connected to the handles 1, 2 by Bowden wire mechanism 18. The outer ends of the arms 4, 5 are connected by a spring 21 which is stronger than the combined strength of the springs 12, so that when the handles are moved together, the jaws 10 are first moved to grasp the object, and on exerting further pressure the grips 7, 8 move in an arcuate path about the pivot 3 so as to expand the piston ring &c. In a modification, the handle 1 is coupled to arm 5, and handle 2 to arm 4, so that the arms are caused to approach one another, for closing the curved object ; in this case, 21 is a compression spring. In a further modification one of the handles 1, 2 and one of the arms 4, 5 are fixed with respect to each other, both Bowden mechanisms being actuated by the free handle. The gripping faces of the jaws 9, 10 converge outwardly so that the object is gripped on its inner periphery.

IPC: G01B13/12
Filed: 1948-01-30
Abstract: 647,009. Indicative position of turbine parts. FAIRWEATHER, H. G. C. (Svenska Turbinfabriks Aktiebolaget Ljungstrom). Jan. 30, 1948, No. 2859. [Class 110(iii)] [Also in Group XIX] The position of the rotor 3 relative to the stator 4 of a turbine is gauged by pneumatic means comprising built-in gauging devices 5 of the nozzle or feeler pin type, and an external manometer 9 connected to a distribution valve 7. In the example, conduits 6 terminate in nozzle tubes 5 mounted at spaced points in the fixed disc of a labyrinth packing. Measurement is effected between the nozzles 15, Fig. 3, of the tubes 5 and the inner machined surface of ring 12 comprising part of the labyrinth. In a modification, Fig. 4, a feeler pin 20 contacts the inner surface of the ring 12 and an obturator 21 having a frustro-conical surface regulates the escape of fluid pressure. In a further modification a lever 31 contacts the inner surface of the ring 12 by means of the anvil 30 and is biassed by a spring 33 to close the valve 35. When contact is made by the anvil 30 against the inner surface of the ring 12 the escape of the fluid past the valve 35 may be measured on the manometer 9 as before. In effecting measurements of clearance between rotary and stationary labyrinth discs in order to determine wear the rotary system is prized to a number of positions and a number of readings taken in each indicator. The average amount thus obtained represents the average clearance. By comparison with previous readings variations in clearance may be recorded.

Abstract: 1,144,173. Heat-treating niobium-zirconium alloys. GENERAL ELECTRIC CO. Ltd. April 7, 1967 [Jan.21, 1966], No.2981/66. Heading C7A. A binary alloy of niobium and zirconium for superconductive use is heated to a temperature at which it has an all-beta structure, and is then cooled rapidly to a relatively low temperature e.g. ambient, such that the single-phase beta structure is retained but metastable, although sufficiently persistent for working to be effected. After the alloy has been worked into wire or strip it is heated at an intermediate temperature at which a multi-phase structure is developed, and is then cooled without destroying that structure. The alloy lies preferably within the range 90 Nb/ 10 Zr to 10 Nb/90 Zr expressed as atomic percentages, while the working step may include swaging and/or drawing through dies. As exemplified, a 75 Nb/25 Zr alloy is homogenized at 1500 C., and is then quenched; after working it is reheated to 700 C. for 20 hours.

Title: Improvements in protecting devices for electric circuits
IPC: H01T2/02
Filed: 1930-01-29
Abstract: 353,924. Protective arrangements. EDISON-SWAN ELECTRIC CO., Ltd., 123, Queen Victoria Street, SHOTTER, G. F., 14, The Ridgeway, Friern Barnet, both in London, and GREETHAM, E., 27, Louis Street, Hull. Jan. 29, 1930, No. 3084. [Class 38 (iv).] A protective device against excess voltage comprises an electric discharge tube having normally cold electrodes of a refractory material and filled with a permanent gas such as neon or a mixture of such gases the shape and arrangement of the electrodes and the pressure and nature of the gaseous filling being so correlated that at normal voltage no current passes through the tube. Excess voltage causes first a glow discharge and, when the current rises, an arc discharge. To offset the negative characteristic of the arc a trace ol gas having a high thermal conductivity, as hydrogen, may be introduced. Two of the electrodes 4, as shown in Fig. 1, may be connected to the conductors and the third to earth. The electrodes are shaped so that the discharge takes place at the points and shrouds 8 of metal of high heat conductivity or of insulating material also facilitates localizing of the arc. Auxiliary electrodes 9 as shown in Fig. 2 may be introduced and connected to the main electrodes 4 through resistances 10. Various applications are described and the discharge current may be used to energize the tripcoil 19, as shown in Fig. 5, to open a main circuit-breaker.

Title: Improvements in or relating to weighing scales
IPC: G01G1/00
Filed: 1927-05-12
Abstract: 284,613. Dayton Scale Co., (Assignees of Bruce, J. W.). Nov. 26, 1926, [Convention date]. Divided on 281,220. Pendulum-weight apparatus.-A weighing scale comprises a scale beam, a pair of load-counterbalancing pendulums, means comprising a flexible tape for driving one of the pendulums from the scale beam and an indicator driving mechanism driven from the first pendulum for conjointly operating the indicator and for driving the other pendulum, the indicator driving- mechanism comprising a pivotally - mounted member so proportioned in relation to the structure of the first pendulum as to receive an increased angular travel with respect to the angular travel of the first pendulum, and other relative proportions between said pivotallymounted member and the other pendulum whereby the two pendulums operate together with an equal displacement. The draw rod 25 from the platform levers is connected to a scale beam 27 pivoted on knife-edges 31. The beam carries a zero-adjusting weight 46 and is coupled to a dashpot 68. A flexible tape 44 connected to one end of the beam is secured succcessively to sectors 55, 61, 61<1>, 56 forming parts of structures 59, 80, 60 mounted on pivots 53, 62, 54. Pendulum weights 51, 52 are adjustable radially on the structures 59, 60, and all the structures are in neutral equilibrium so that the pendulum weights alone provide the balancing moment. A rack 40 pivoted on a pin 40a upon the structure 80 actuates an indicating pointer through a pinion 63. The sector 55 which is of a varying radius to give an equally-divided indicating dial is of greater radius than the sector 61, and the distance from the rack pivot 40<a> to the pivot 62 is greater than the radius of the sector 61 but less than the radius of the sector 56. Owing to these relative proportions the movement of the pendulum structure 59 produces an increased movement of the indicator driving mechanism and an equal displacement of the pendulums. In the unloaded position of the scale, the pendulums are inclined as shown and with this arrangement if the scale is out of level the consequential errors introduced into the system compensate one another as described in Specification 281,220. The pivot shaft 31 of the beam 27 is extended through the casing and carries a diverging bracket on which two beams are mounted. Specification 259,548 is referred to.
