Title: Method of making a concentric wire rope on a double twist strander
IPC: D07B1/06
Filed: 1973-03-22
Abstract: 1367609 Making wire ropes MORGAN CONSTRUCTION CO 22 March 1973 [27 March 1972] 13834/73 Heading D1T A method of making a regular lay wire rope in which the lay of the core strand is opposite to the lay of the wires of the individual outer strands surrounding said core, comprises the steps of continuously supplying a plurality of outer strands of the same lay and a core strand of the opposite lay to an initial twisting position of a double twist stranding machine, twisting together said continuously advancing outer and core strands at said initial twisting position to start a concentric regular lay wire rope in which the wires of said core strand are twisted more tightly to shorten their lay and the wires of said outer strands are untwisted to lengthen their lay, passing the partially twisted rope to a second twisting position of said machine to complete the twisting of all the strands in the same direction thereby to furhter shorten the lay of the wires of the core strand and to further lengthen the lay of the wires of said outer strands and to shorten the lay of the outer strands, the additional shortening in length of the core strand at the second twisting position being at least as great as any additional shortening in length of the outer strands at the second twisting position. Fig. 2 shows the core strand 60 surrounded by six outer strands 72, 74, 76, 78, 80 and 82. The lay of the wires 62-68 of the core strand 60 is opposite to the lay of the wires in each of the outer strands 72-82. In a double twist strander, Fig. 1 (not shown), floating supply spools (16, 18) supply all seven strands to a first rotating stranding point (46) where the outer strands are twisted around the core strand 60, such twisting action resulting in the lay of the core wires 62-68 being shortened and the lay of the wires of the outer strands 72-82 being lengthened. The resulting rope then passes to a second stranding point (58) where the lay of the wires of the core strand are shortened still further and the lay of the wires of the outer strands are lengthened still further.

Title: Absorbent fibrous bodies
IPC: A61F13/15
Filed: 1957-05-01
Abstract: 890,682. Surgical dressings. BURGENI, A. A. May 1, 1958 [May 1, 1957; Sept. 26, 1957 (2)], Nos. 13929/57, 30269/57 and 30270/57. Class 81 (2). [Also in Group VIII] An absorbent component of a surgical dressing is made by moistening a surface of a porous, loosely compacted single-layered fibrous bat and applying pressure to form an integral densified paper-like skin at the moistened surface. The bat 12 which is made from comminuted wood pulp fibres or cotton linters which may be combined with fibres of silk, linen, wool, nylon or cellulose acetate, has a compacted paper-like layer 14 on its upper and/or lower surfaces. Two such bats may be pressed on top of one another to provide a pad with compacted layers on its upper and/or lower surfaces and across its interior the area of the compacted layer may be smaller than the area of the surface on which it is formed. Longitudinal or transverse grooves 63, 64 may be formed on the bat surface during compression, regions of higher and lower capillarity being thus formed in the compacted layer. A catamenial napkin 66 is formed from an upper pad 67 having a grooved compacted layer 69 and separated by water-repellent tissue 70 from a lower pad 62 having an upper embossed compacted layer, the two pads being wrapped in paper 71 and a textile cover 72. A pad 19 (Fig. 4) comprising bats 20, 21 with a compacted layer 22 between them is formed by compressing superimposed webs 73, 74 (Fig. 16) between rollers 80, 81, the upper surface of the lower web 74 having been moistened by a spray 75. The compression rollers may be shaped to produce lateral or transverse grooves or other embossing in the compacted layer. The compression rollers may be separated from the web surface by an endless band, of natural or synthetic fibres, glass filaments, wire or rubber threads, which after passing between the rollers is peeled from the treated web at an obtuse angle to the direction of travel. The endless band may pass through the moistening agent so that it moistens the web surface on passing between the compression rollers. The amount of moisture applied to the bat is between 0.0005 and 0.03 c.c./sq. cm. and the pressure applied is between 5 and 100 lbs./sq. inch. The bat surface is moistened by water, glycols, glycerol or sorbitol. The liquid applied may contain bactericides, fungicides, softening agents, sizes, adhesives or textile sizing or finishing agents, e.g. starches, dextrins, casein, cellulose, polyvinyl acetate, polyvinyl chloride, waxes, dibutoxyethyl phthalate. Wadding, paper or gauze may be applied over the compacted layer during compression. Specification 482,343 is referred to.

Filed: 1942-10-13
Abstract: 559,578. Locking nuts. BEALE, R. D. Oct. 13, 11942, No. 14358. [Class 89 (i)] Nuts are locked by washers having projections 3 on one face and a series of outwardly bent tongues 7 on the other. The washers are used in pairs with the projections placed outwards ; on screwing up the nut 4, the projections 3 embed themselves into the nut and work 5 or are received into grooves formed therein, and the tongues ratchet over one another. The enas of the tongues contact to prevent unscrewing. The tongues are formed by stamping U -shaped holes 8 in the washers. Instead of being radial as shown the projections 3 may be parallel to a diameter. In modifications the tongues may be formed on the internal or external periphery of the washer and the projections may be in the form of closely adjacent radial teeth or of pyramids closely arranged over the whole face, or of conical or like nipples, e.g. three in number, disposed at equal or unequal distances radially from and about the centre of the washer.

Title: Improvements in or relating to disc ploughs
IPC: A01B63/28
Filed: 1919-06-05
Abstract: 144,467. McKay, A. P. June 5, 1919. Ploughs.-A tractor plough is provided with means whereby the carrying wheels are depressed tn raise the plough shares and also has its rear wheel so arranged that it is automatically turned to neutralize the side-thrust due to the ploughs when these are in operation. The disk ploughs 1 which are provided with subsoilers 2 are carried by beams 3 extending to transverse shafts at the forward end of the machine. The road wheel 12 is keyed to a stub-shaft 15, Fig. 6, mounted in a crank-arm 18 keyed to a cross shaft 6. The shaft 15 carries ratchet teeth 23, Fig. 8, which are adapted to engage a tooth 35 on a latch 33 normally held free of the teeth by springs 55, 56 but adapted to be forced into engagement therewith by projections 63, 64 on levers operated by the tractor driver through a cord and pivoted on a casing 20 secured to the crank 18. The latch 33 slides between guides 46, 47 secured to a cap 28 mounted to rotate on the shaft 15 and provided with a projecting arm 29 to which a link 31, pivoted to the main frame, is pivoted. On pulling the cord to force the tooth 35 into engagement with the ratchet, the latch, and with it the cap 28, is caused to rotate until the projection on the latch reaches one or other of two openings 48, 49 in the casing 20 through which it is immediately forced by the tension of the springs 56, thus freeing the latch from the ratchet and stopping the rotation of the cap. As the cap rotates, its connexion with tho link 31 moves from one side to the other of its centre and thus causes the crank 18 to be moved abont the axis of the shaft 6 raising or lowering the forward end of the machine. The furrow wheel 13 which is mounted on a vertical bar 74 sliding in a guide 75, is moved simultaneously with the land wheel through a crank 70 on the shaft 6 connected with a lever 72 pivoted on the bar 74 by a link 71. The lever 72 may be adjusted round a quadrant 83 secured to the bar 74 in order to vary the position of the furrow wheel relatively to the land wheel. The bar 74 is provided with an extension 76 from which the machine frame is hung by a spring the tension of which is adjustable. The rear wheel 14 is mounted on a support 85 extending through an opening in an extension of the subsoiler support of the last plough, and carries the pivot of a bell-crank lever 87 from one arm of which the subsoiler support extension is hung by a link 86. The other arm is connected by a link 90 and independent hand adjustment lever 95 to an arm 93 keyed to and operated with the shaft 6. To turn the rear wheel 14 to neutralize the side thrust of the ploughs, the support 85 is provided with a laterally extending arm which is adapted to be engaged by an adjustable stop 107 on a rod 104 operated by the movement of the arm 93. When the ploughs are lowered and the arm 93 moves backwards, the stop engages the arm and causes the wheel to take up an inclined position. Reference has been directed by the Comptroller to Specifications 113,335 and 115,270.

Abstract: 198,209. Williams, F. W. May 22,1922. Elements moving always in one plane, rotating.-A disc b carrying slides for optical projection is actuated step-by-step, by an electromagnet d on the armature d<1> of which is mounted a pivoted pawl e engaging either pins b<1> on the disc or a toothed wheel geared to the disc-shaft by toothed wheels or by chain and sprocket wheels. A timing device for determining the period of exposure, comprises a pivoted lever m which completes an electric circuit at k and is connected by a cord l to an extension d<2> of the armature d'. When contact is made the armature d' is attracted against a spring h, the pawl e is brought over the next pin b<1> and the cord l pulls over the lever m to break the circuit and to wind up a clock spring. A screw stop n limits the movement of the lever m, and the clockwork, which may have a pendulum escapement, allows the lever m to return slowly and again-make the circuit. When this circuit is made the lighting circuit at i is broken and is not again made until the rotary movement of the disc b has been effected by the spring h withdrawing the armature d<1>. The disc is held stationary by a spring held pawl g which is released by a striker rod f carried by the armature d<1>. The pawl e has a guide e<1> and is prevented from rising too high by a spring.

Title: Improvements in or relating to sinter apparatus
IPC: B65G35/00
Filed: 1961-04-20
Abstract: 988,045. Conveyers. KOPPERS CO. Inc. April 20, 1961 [June 9, 1960], No. 14396/61. Heading B8A. In a sinter apparatus of the Dwight-Lloyd type the apparatus comprises a pair of upper rails 16, 17 and lower rails 18, 19. Pallets 25, mounted on wheels 27, are driven by a pair of sprocket wheels 30, 31 so that they push the preceding pallets from the feed end 20 to the discharge end 21 of the machine. Along the upper run of the apparatus ore is loaded into the pallets 25 from a feeder 22 and ignited by an igniter 23. After discharge of the sinter the pallets 25 return under gravity to the feed end of the machine. The sprockets 30, 31 are driven in unison by a common drive shaft 36. In practice it is found that the pallets 25 do not remain square to the rails 16, 17 at all times but tend to ride against one side or the other (as shown dotted in Fig. 2) causing excessive wear. This fault may be compensated by feeding the pallets 25 with one side in advance of the other. The sprocket teeth 34 (Fig. 7) are made in interchangeable groups the tooth being offset with respect to its base. By having a number of groups of teeth 34 offset by different amounts a wide range of adjustment is possible. U.S.A. Specification 2,534,187 is referred to.

IPC: H04Q3/00
Filed: 1954-05-17
Abstract: 787,238. Automatic exchange systems, STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. May 17, 1954 [May 23, 1953], No. 14458/54. Class 40 (4). In an automatic exchange system in which calls between calling and called subscribers are set up over four interstage links, the first and fourth of which lie between primary and secondary switches, the former being used both for connecting to calling and called subscribers, the secondary switches are connected via tertiary switches in such a manner, that a connection may be established via any of the primary-secondary links serving the calling subscriber and any primary-secondary link serving the called subscriber. Thus, as shown, in a 10,000 line exchange each group of a thousand lines is served by 50 groups of 20 outlet primary switches, each group comprising 7 switches cross-connected to 7 sub-groups of 7 50-outlet outgoing secondary switches connected to outgoing connecting circuits u. Each sub-group of outgoing circuits u is crossconnected to a group of 7 tertiary switches whose outlets are also accessible from corresponding sub-groups serving other 1000-subscriber groups. The tertiary switches are set in accordance with the identity of the thousands group containing the called subscriber and the corresponding outlets of a group are connected to incoming circuits i belonging to different sub-groups of the main group serving the called subscriber. Access therefrom is obtained to the called subscriber over an appropriate primary switch. Thus a call may be routed over the mth (last as shown) primary-secondary link serving the calling subscriber, the nth (first as shown) outgoing circuit of the mth sub-group, the mth inlet of the nth sub-group of the mth group of tertiary switches, the mth incoming circuit of the nth sub-group of outgoing circuits and the nth primary-secondary link serving the called subscriber. If the number of connecting circuits per sub-group is less than the number of links per group of 20 subscribers an incomplete system may be devised on the above principles. In the reverse case a complete system based on. the lower number may be devised together with a supplementary incomplete system. Thus if 8 secondary switches per sub-group and 6 links per 20 subscribers are required, a complete system based on 6 secondary switches per sub-group is first devised. The remaining 6 X 2 secondary switches per 1000 subscribers may then be provided with a further 6X2 tertiary switches connected according to the plan illustrated in Fig. 3. The tertiary switches may be given access to outgoing inter-exchange lines, and incoming inter-exchange lines may be given access to incoming connector circuits over finder-selector links, Fig. 1 (not shown).

Title: Process for the separation of hydrocarbons
IPC: C07C7/11
Filed: 1961-04-21
Abstract: Olefins are separated from saturated hydrocarbons by contact with an aqueous solution of silver fluoborate and/or fluosilicate and a stable fluoborate or fluosilicate of a second metal of which the cation has a ratio of charge to ionic radius in Angstrom units greater than 1.  The second metal is preferably beryllium, magnesium, calcium, zinc, strontium, cadmium, barium, copper, lead, lithium or sodium.  The molar ratio of silver to second metal may be 1-10:1 and the concentration of the second metal 4-12 molar.  Absorption is effected at 0-50 DEG C. by passing the hydrocarbons through the solution or by mixing and the olefins recovered by heating to above 80 DEG C. and/or by reducing the pressure.  Acetylene concentrations in the hydrocarbons should be below 1%.  Diolefins are separated from mono-olefins by virtue of the diolefins forming a solid precipitate, which can be removed and separately decomposed, when using silver fluoborate at concentrations above 6 molar.  Specification 859,440 is referred to.
