Title: Improvements in coupling devices suitable for railway vehicles
Inventor: AXTEN ERNEST WILLIAM
IPC: B61G3/18
Filed: 1957-10-15
Abstract: 843,365. Automatic couplings for railway vehicles. DOWTY HYDRAULIC UNITS Ltd. Sept. 30, 1958 [Oct. 15, 1957; Nov. 27, 1957; Dec. 2, 1957], Nos. 32222/57, 37027/57, and 37510/57. Class 103(5). An automatic coupler for a railway vehicle comprises gathering horns 1, 2 having parallel portions 5, 6, a base 8 including a forwardly opening slot 9 housing a C-shaped latch 11 pivoted at 12, and a cam surfaced pawl 15 having a locking arm 26 which engages the latch of a similar co-operating coupler to lock the couplers together. In the preferred embodiment the coupler is inclined at 45 degrees and the latch 11 has a forked tail 19 which is engaged by a cap 23 urged thereagainst by a spring 18, the other end of which spring enters a hollow housing 17 having a shoulder 20 and presses a cap 22 against a flat 21 cut into the pawl operating spindle 16 so that the pawl is urged into the latch locking position. The latch is provided with a tip 13 having a chamfered outer surface 31, a locking surface 34, and a surface 32 concavely curved about the latch pin 12 as centre and also convexly curved in a plane at right angles thereto. When two couplers come together in mutual alignment one latch may lift as in Fig. 4, and when it drops back to the coupled position the surface 31 will engage the locking member 25 causing the pawl 15 to rotate backwardiy about its spindle 16 so as to compress the spring 18. The latch 11 then drops into engagement with the latch of the cooperating coupler and the pawl springs back to engage its locking surface 28 over the surface 34 of the latch. The other coupler latch may not however lift but move directly into the position where its locking surface 34 slides under the surface 28 of the other locking pawl. The pawl may be disengaged from the latch, Fig. 6, by moving a lever 38 connected by a chain 37 to an arm 36 on the pawl spindle 16 and causing the pawl to rotate and its arm 26 to lift the latch. When the latch is lifted clear a parting force, exerted for example by compression in the side buffers, moves the couplers apart. During shunting the couplers may be prevented from engaging by moving the lever 38 into a gate 39 so that the arm 26 will be positioned as in Fig. 6 to prevent the latch from falling into position. In the case where a latch does not lift, the surface 31, Fig. 6, will strike and ride up the arm 26, the pawl itself being prevented from rotation by engagement of the end cap with the shoulder 20. Buffing projections 41 are provided to prevent relative inward movement of the couplers beyond that necessary for engagement.

IPC: C09B17/02
Filed: 1928-11-06
Abstract: 300,178. I. G. Farbenindustrie Akt.- Ges. Nov. 7, 1927, [Convention date]. Azine dyes.-Safranime dyestuffs which dye wool from an acid bath blue to violet shades are prepared by oxidation of a 4-acidylamino-3<1>- amino- or 4-nitro-3<1>-amino-diphenylamine-2-sulphonic acid or homologue or derivative thereof with a p-phenylenediamine or a derivative thereof. The acidylamino group in the product may be saponified and the nitro group may be reduced, e.g. by means of zinc and acetic acid or by alkaline hydrosulphite, the resulting leuco compound then being oxidized. The benzene nuclei, other than the azonium benzine nucleus, may contain alkyl, halogen or sulphonic substituents. The amino groups may be substituted by alkyl and aryl groups. According to examples. the following pairs of components are condensed by oxidation. : (1) 4-acetamino - 3<1>- -amino-4<1>- methyldiphenylamine-2-sulphonic acid and 4- ammo-4<1>-methoxy-diphenylamine-2-sulphonic acid or 4-aminodiethylaniline-3-sulphonic acid; (2) 4- nitro - 3<1>-dimethylaminodiphenylamino-2-sulphonic acid and 4-aminodiphenylamine-2-sulphonic acid or 4-amino-4<1>-methoxydiphenylamine-2-sulphonic acid. 4-Nitro-3<1>-aminodiphenylamine-2-sulphonic acid and the corresponding 3<1>-alkylamino-, and 31-arylamino-derivatives may be obtained by condensing 1 : 3-phenylenediamine or its asymmetric N-alkyl or aryl derivatives with 4-nitrochlorbenzene-2- sulphonic acid. 4-Acidylamino - 3<1>- aminodiphenylamine-2-sulnhonic acids and derivatives thereof may be obtained by reduction, and partial acidylation, of the corresponding nitro compounds. 4-Acetylamino - 3<1>-amino-4<1>-methyldiphenylamine - 2 - sulphonic acid (example 1) may thus be obtained by condensing 4-nitrochlorbenzene-2-sulphonic acid with 4-methyl-1 3-phenylenediamine, reducing and partially acetylating. 4 - Amino-4<1>-methoxydiphenylamine-2-sulphonic acid (example 1) is prepared by condensing 1- methoxy-4-aminobenzene with 4-nitro-1-chlorbenzene-2-sulphonic acid, in the presence of an acid binding agent, and reducing the 4-nitro-4<1>- methoxydiphenylamine-2-sulpbonic acid with iron and dilute hydrochloric acid. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of 4-nitro- 3<1> - aralkylaminodiphenylamine-2-sulphonic acids as starting material.

Abstract: 618,193. Turbines. SMITH, D. M., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 31, 1946, No. 32382. [Class 110 (iii)] A reversible internal-combustion turbine comprises a stator provided with movable vanes to impart swirl in one direction or the other to the working medium and a rotor formed with fixed vanes which extend substantially in radial planes and define passages which increase in cross-section between the inlet which is at the periphery of the rotor and the outlet which is near the axis of the rotor. Working medium enters the turbine through a volute 2 and swirl is imparted to the flow by passages 3 between the adjustable stator vanes 4. To reverse the direction of rotation the vanes are swung to the position shown in dotted lines in Fig. 1. The vanes 4 are pivotally mounted in bearings 6 and are simultaneously operated by means outside the casing. The rotor 7 is provided with vanes 8 which extend in radial planes in an axial direction. In a modification, the rotor 7 is made conical and the working medium flows from an annulus concentric to the shaft at the periphery of the rotor through the rotor to a similar annulus near the axis of the rotor. The flow through the stator vanes 4 is then axial. The movable vanes may also be used for braking the rotor, by moving them into the neutral or reverse position. The ends of the rotor vanes 8 may be bent in one direction or the other to improve the efficiency of the turbine when rotating in one particular direction.

Abstract: 372,270. Electric signalling systems. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, and HERSHEY, H. E., 947, West Van Buren Street, Chicago, U.S.A. Oct. 28, 1930, No. 32399. Convention date, Oct. 30, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (i).] A system for signalling times of departure of trains, stock quotations, &c., comprises key strips TH-U for the maximum number of digits, a stepping-switch FS having banks each associated with one of the strips, a relay set, Fig. 1, for controlling simultaneous impulsing over separate wires 47 .. 50 for each digit, and a set of indicators R1 .. R4, Fig. 2, constructed as shown in Fig. 3. On operation of a release key at the transmitter or receiver the indicators are stepped to normal under control of the relay set shown in Fig. 2. Two sets of indicators are shown in Fig. 2, either of which may be operated by the transmitter, Fig. 1, the set being selected by keys K1, K2. When the final digit is keyed on set U, ground over the key operates relay 15 and magnet 24, the relay being slow-to-operate. The magnet operates impulsing relay 16 and when it relapses on operation of 15, FS takes a step and 17 operates over off-normal contacts ON and re-operates the magnet so that the switch is stepped by interaction between 24, 17. Slow-to-release relays 18, 19 hold up during the impulsing. As the wipers 11 .. 14 reach the contacts marked by the keys relays 23 .. 20 pull up, lock, and open the impulsing circuits. When the switch FS has stepped to normal, 17 remains de-energized, and 18, 19 fall back in turn to send a ground pulse to the keyrelease magnet. Assuming that key K1 has been thrown to connect the upper receiver in Fig. 2, the first impulses over conductors 51 .. 54 operate the magnets 95 of the indicators over normal contacts 98 and the upper winding of relay 65 which locks up and lights lamp L1, Fig. 1. Subsequent impulses operate the magnets 95 over contacts 99. The indicators comprise cylinders 90, Fig. 3, bearing circumferential numbers 1 .. 0 :and a blank space which is normally visible through a window 100. The cylinder carries a coaxial ratchet wheel 92 and cam 96, and springs 97, 98 are normally closed by projection 101. The cylinder takes half a step for each operation and each relapse of magnet 95. The indicators are reset by operation of key RK1, Fig. 1, or RK3, Fig. 2, which operates 66. Battery over the magnets 95 is connected to slow-to-operate relay 67 which energizes slow-to-operate relay 68 and slow-to-release relay 69. Relay 70 also pulls up, and relays 65, 66 are held by 69, and key RK1 or RK3 may be released. The magnets do not operate in series with 67, but are stepped by interaction between 67, 68. As each indicator reaches normal, its stepping circuit is opened by cam 96. When all the indicators have reached normal, 67 remains inert and the remaining relays at the receiver fall back, lamp L1 at the transmitter being extinguished.

Title: Joint prosthesis
IPC: A61F2/30
Filed: 1977-08-03
Abstract: In order to prolong the useful life, the outer surface area of the tubular prosthesis shaft has a screw thread. The shaft is preferably made from carbon fibre reinforced plastic and is anchored without cement in the medullary cavity of a bone. This is only possible because the shaft is provided with openings or bores through which the vessels supplying the bone grow. The production method advantageously involves winding carbon fibres onto a mandrel, impregnating the wound structure with a curable synthetic resin, heating the wound structure for the purpose of curing and carbonising the synthetic resin, providing the wall of the resulting prosthesis shaft blank with a plurality of openings by means of boring, and cutting a screw thread into its surface area.
