Title: Improvements in or relating to impulse transmitters for use in telephone or like systems
IPC: H04M1/18
Filed: 1924-07-14
Abstract: 234,036. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Obergfell, H. F.). May 15, 1924, [Convention date]. Impulse-transmitters of the dial type (shown disassembled in Fig. 1 and in rear view in Fig. 3) comprise the following features : -(1) The complete dial is secured to a telephone instrument by lugs 48, 48<1> on the impulse-spring bracket 80 which is in turn fixed to the base of the cup member 25 by screws 47, 47<1> so that the remainder of the instrument may be readily removed without interfering with the springs. (2) The main shaft 20 is mounted in a single bearing formed in a hub 27 and is held therein by the driving spring 82, Fig. 3, whilst. the finger plate 10 is fixed to a plata 18 on the shaft 20 by a screw 9, the plate 10 thus being removable without disturbing the shaft 20 and the impulse mechanism. The plate 18 carries a driving pawl 35 and is also provided with stops 72, 73 which limit the motion of the dial. (3) The number plate 15 fits into a ledge in the top of cup 25 and is held by spring arms 26, 26<1> hooking over a shoulder 81. (4) The instruction card 7 and celluloid disc 5 are held by a ring 1 carrying spring members 2, 3, 3<1> engaging corresponding holes in the finger plate 10, an inwardly-projecting spring member 4 engaging with notches 6, 8 to determine the relative positioning of discs 5, 7. (5) A plate 44 screwed to the cup member 25 is provided with two projections 29, 29<1> extending upwards through notches 74, 75, one or other projection forming the finger stop 11, whilst the remaining one is cut off, according as a pause between two series of impulses is or is not required. The plate 44 provides the upper bearing for the shaft 59 carrying the impulse cam 55, Fig. 3, the other end of the shaft being supported in an arched bracket 57. The plate 44 also carries a stop 33 co-operating with the stops 72, 73 to limit the motion of the dial. (6) A unit comprising a toothed wheel 24 geared to a worm wheel 71 on the shaft 59 and a ratchet 23 engaged during the return movement by the pawl 35 on the plate 18 is frictionally held between washers 21, 58 so as to prevent the impulse cam from running ahead of the finger plate 10. The return movement of the mechanism is braked just before the normal position is reached by the pawl 35 engaging a resilient stop 30 on the plate 44. (7) With the finger stop 11 in the position shown in Fig. 1, the shaft 20 carries an arm 53 which in the normal position and during the last half-revolution of the shaft 59 holds the impulse springs 39, 40 out of reach of the impulse cam 55, thus rendering the last half-revolution ineffective to generate an impulse. A further arm 51 controls the normally-open shunt springs 36 - - 38. Specifications 135,416 and 226,152 are referred to. The claims in the present Specification relate to the first five features enumerated above. Other features of the impulse transmitter described herein form the subject-matter of a divided Specification 237,290.

Title: Improvements in or relating to electromagnetic relays
IPC: H01H51/27
Filed: 1962-05-03
Abstract: 999,517. Electromagnetic relays. WESTERN ELECTRIC CO. Inc. May 3, 1962 [May 15, 1961], No. 16941/62. Heading H2B. [Also in Division H1] An electromagnetic relay comprises a sealed magnetic contact unit with a pair of magnetic control members having a plurality of stable remanent magnetic states, a first control winding encompassing one of said members, and a second control winding on compassing the other of said members, the windings being connected in series and wound to produce opposing fluxes, and a rectifier connected in parallel with one of said coils. As shown in Fig. 1, the reeds 12, 13 constitute the control members and are surrounded by windings 16, 17, respectively, 17 being shunted by a rectifier 18. On energization by a positive pulse, coil 16 is energized but coil 17 is shunted by rectifier 18. The coil 16 tends to magnetize the reeds in the same sense so that they close. When a negative pulse is applied both coils are energized, magnetizing the reeds in opposite directions so that they open. In Fig. 2, both of the contact units are surrounded at one end by a coil 29 and by separate coils 27, 28 at the other end, the coils 27, 28 being electrically connected to coil 29 and being so wound as to produce fluxes in opposition to coil 29. Oppositely poled rectifiers 31, 32 shunt coils 27, 28 respectively. When a negative pulse is applied rectifier 31 shunts coil 27, and coils 28, 29 are energized. Reeds 24, 26 are oppositely polarized and therefore open, whilst reeds 22, 23 are similarly magnetized and therefore close. When a positive pulse is applied only coils 27, 29 are energized causing reeds 24, 26 to close and reeds 22, 23 to open. The control members may be in the form of sleeves of magnetic material surrounding each reed. Specifications 870,906, 941,653 and U.S.A. Specification 2,877,316 are referred to.

Abstract: 844,347. Hinges and pivots. GENERAL MOTORS CORPORATION. May 28, 1958 [June 19, 1957], No. 17002/58. Class 65(2) The pivot head 12 of a stud 10 is formed as a frustum of a convex non-spherical body generated by the rotation of a curved line about the longitudinal axis of the stud, and is encased in bearing halfshells 16, 18 separated by a plane perpendicular to the axis of the stud and secured to an elastomeric bushing 28, 30. Preferably, the radius of curvature of the curved line is greater than its greatest distance from the axis and the plane which separates the half-shells 16, 18, also separates the halves 28, 30 of the bushing and contains the greatest diameter of the head, about which the latter is symmetrical. The bearing half-shells are bonded to the bushing and have end flanges 20, 22, 24, 26 which interlock with the bushing and facilitate the deformation of the latter when the stud tilts relative to the socket 32. A plurality of internal ribs or projections may be formed in the shells to prevent them from binding to the head 12 and to permit lubricant to flow therebetween. To further facilitate deformation of the bushing, spaces 53, 55, and an annular space 46 co-planar with the plane separating the half-shells, are provided to allow the elastomeric material to flow. The elastomeric material may be natural rubber, butadiene-styrene co-polymer, butadiene-acrylenitrile co-polymer, polychloroprene, polysulphide rubber, or mixtures thereof.

Patent GB-459781-A (GB)
Title: Improvements in the manufacture of artificial yarns
IPC: D02G1/02
Filed: 1935-06-14
Abstract: A process for the production of voluminous yarns comprises crinkling a yarn containing flat filaments, which are composed of an organic derivative of cellulose and which contain a plasticizer for the cellulose derivative, by treatment with a hot aqueous medium.  In this way a considerable crinkle or crimp is imparted to the filaments.  If desired the yarn is converted into one containing staple fibre and/or is twisted, set and untwisted before or after the hot aqueous medium is applied.  The treatment with hot aqueous medium may be a steaming or an immersion in hot aqueous liquor, which may contain a suitable wetting agent, e.g. monopol soap or turkey red oil or other sulphonated higher aliphatic compound.  The treatment may be for \ba1/2\be--1\ba1/2\be hours at the boil with a liquor containing up to 1 gram of wetting agent, and may be sufficient to remove the plasticizer.  The treatment may take place under pressure, and may be modified, e.g. by addition of salts or sugars to the hot aqueous medium to control the lustre of the finished product as described in Specifications 246,879 and 260,312, [both in Class 15 (ii)].  The production of flat filaments may be effected by adjustment of the concentration of cellulose derivative and/or of plasticizer in the spinning solution.  They may be produced by spinning a 27,5 per cent solution of cellulose acetate in acetone containing 20 per cent of paradichlorbenzene based on the weight of cellulose acetate.  The plasticizer may be water soluble, e.g. glycerol or glycol, or difficultly soluble in water e.g. paradichlorbenzene or diphenyl.  It should desirably be substantially non-volatile, and not compatible with the cellulose derivative in too high a proportion.  Examples of plasticizers mentioned as suitable are orthodichlorbenzene, dibutyl or diamyl phthalate, and acidylated aromatic amines or amides of aromatic sulphoned or carboxylic acids.  Conversion of the yarn into one containing staple fibre may be effected by cutting the yarn to staple fibre and respinning or by a direct conversion process, e.g. as described in Specifications 424,683, 424,752, 424,830, and 424,879, [all in Group IX].  If an operation of twisting, setting the twist and untwisting is to be applied, the setting is preferably carried out on the travelling yarn, e.g. during the twisting or untwisting operation.  Steam is the best setting agent.  Suitable processes are described in Specifications 424,880 and 442,073, [both in Group IX].  It is desirable to finish with a doubled yarn having a light doubling twist reverse in direction to any twist in the constituent yarns, which is also preferably light.

Title: Improved petroleum conversion catalyst
IPC: B01J27/13
Filed: 1952-07-08
Abstract: A hydrocarbon conversion catalyst is prepared by treating dried activated alumina with a solution of a platinum or palladium compound, drying the mixture and treating it with hydrogen fluoride. The activated alumina may contain 1-10 per cent. of silica.  When using aqueous solutions of chloroplatinic acid or palladium chloride, some of the chlorine remains in the final catalyst.  The dried impregnated alumina may be mixed to a paste with aqueous hydrogen fluoride or may be treated with dry gaseous hydrogen fluoride diluted with an inert gas.  Ammonium sulphide or hydrogen sulphide can be included in the hydrogen fluoride solution as a precipitating agent for the platinum or palladium. The catalysts are suitable for use in hydroforming naphthas, either in a fixed bed or fluidized bed process, especially at pressures up to 300 lbs. per sq. in. Carbonaceous deposits on the catalyst may be removed by treatment with hydrogen or by controlled combustion with air.

Patent GB-681112-A (GB)
Title: Improvements in or relating to the simultaneous dehydrogenation and hydrogenation ofhydrocarbons
IPC: C07C5/52
Filed: 1950-07-11
Abstract: The simultaneous dehydrogenation of naphthenes to aromatics and hydrogenation of olefins to paraffins is effected by contacting gases containing them with activated carbon at 750-1100 DEG  F., preferably 900-1000 DEG  F.  The naphthenes should contain more than four cyclic carbon atoms and are preferably cyclohexane and its homologues. Olefins of 2-10 carbon atoms are suitable, e.g. ethylene, propylene, butenes, butadiene, isoprne, and vinyl ring compounds, e.g. styrene. A stoichiometric ratio of naphthene to olefin gives high conversion to aromatics, while excess of naphthene increases the paraffin yield. Single or multipass operation with fixed, moving or fluidized catalyst may be used.  Iso-olefins are hydrogenated in preference to normal olefins whereby separation of isomers may be effected.  Where isoparaffins are desired, the active carbon may be mixed with a catalyst to isomerize a normal feed to iso-olefins.  The total feed rates are from 0.1-10 liquid vols. per vol. of catalyst per hour. Contact times are, for example, 0.1-1 sec.  The carbon may be derived from vegetable matter decomposition products, lignite, petroleum sources, bituminous coal or pure organic compounds.  A carbon of coal origin having a high surface area of 1000-1100 sq. m./g. is suitable. Regeneration is effected with inert gas such as steam, nitrogen or flue gas at 1350-1600 DEG  F.  Unconverted reactants may be recycled with fresh feed.  Inert diluents, for example, one of the products may be used.  Examples describe and illustrate the reaction of methylcyclohexane and butene-2 or C6 olefin polymer and compare the activity of carbon with that of other catalysts; the comparative reactivity of iso- and n-butenes; the reaction of methylcyclohexane and isoheptene or isohexene; the effect of temperature and feed rate on the conversion; and reaction of virgin naphthenic naphtha with light-cracked naphtha.

In a pivoted vibrator producing rotary motion by means of a friction ratchet 28, the electromagnet has three poles 6, 5, 6, of which the centre pole 5 carries the A.C. energizing coil 10, and the armature 2 has a pair of poles which interdigitate with these poles so as to produce four working air-gaps, i.e. in the half of the machine shown by sectioning, gaps 11, 23 and 12, 24. The armature is pivoted by means of side-plates 25 about the centre of the ratchet mechanism 28 and they are secured together by three rivets 27 passing through spaces in the ratchet mechanism. The armature comprises a permanently magnetized centre portion 19, e.g. of ferrite or an electromagnet, having soft polepieces 22 projecting from its upper and lower surfaces, which carry restraining screws loaded by springs 18 of dished disc type. These polepieces are notched to receive the ends of the pivot-plates 25 (Fig. 3, not shown). The driving hub 4 of the output shaft is constrained to clockwise rotation only by the rollers 31 of the ratchet and is kept in frictional engagement with one of the oscillating side-plates by the axial pressure of wave-spring 36. This frictional drive may be replaced by a further ratchet drive (Fig. 10, not shown). The winding may be on the moving member and the stator permanently magnetized. A modification is described in which the electromagnet core as a whole oscillates against non- linear lateral springs, the armature being stationary and the spring-pressure adjustable by wedges (Figs. 4 and 5, not shown). In a further modification (Figs. 6 and 7, not shown) the whole device is resiliently mounted in that it is pivotally mounted by its output shaft (which is extended at either end for the purpose) and is resiliently prevented from turning by a pair of springs. A double-acting ratchet arrangement is described (Figs. 8 and 9, not shown) in which additional ratchets on either side of the device are operated in reverse sense to the normal ratchet through a lever linkage.
