Filed: 1973-07-26
Abstract: 1395848 Railway vehicles SCHWEIZERISCHE LOKOMOTIV-UND MASCHINENFABRIK 26 July 1973 [26 July 1972] 35590/73 Heading B7L A railway locomotive has a frame 1 supported by a bogie 3 with driven axles 5, traction forces being transmitted to the frame by rods 6 located in a vertical plane at an angle 2 to the horizontal and which intersect at rail level, a tension being produced in each rod, which together are greater than the tension produced by the driving forces, by a spring 12 acting through pivoted double arm levers 10 which with an increase in tension in one rod produce an equal reduction in tension of the other rod and which also produce equal but opposite movement of one rod in response to movement of the other. In Fig. 2 spring 23 tensions rods 24, 26 by acting on double arm levers 21, 22 indirectly, via rod 25, and directly respectively, the rods 24, 26 being pivoted to a rod 27 by connections disposed on shoes 30 which can slide on the underside of bogie 3. Rod 27 has a bearing ring 28 which embraces a pivot 29 enabling the bogie to rotate. The rods may be tensioned by hydraulic cylinders (Fig. 3, not shown), interconnected by lines to the chambers of a cylinder having a stepped bore and a differential piston whose two faces are of equal size the piston being biased by mechanical or hydraulic means. An existing locomotive may have a compensating system fitted to it by the addition of a parallelogram linkage, Fig. 5, which produces the tension in the rods by the pair of springs 49, or in a modification by a single hydraulic cylinder.

Title: Catalyst for the polymerisation of air-drying unsaturated polyester resins
IPC: C08F283/01
Filed: 1955-12-14
Abstract: Unsaturated polyesters derived from polyhydric alcohols having condensed ring systems with endomethylene groups, are copolymerized with 20 to 50 per cent of a vinyl compound, e.g. styrene, by the use of 3 to 6 per cent of cumene hydroperoxide preferably dissolved in a hydrocarbon.  The polyhydric alcohols may be derived from Diels-Alder adducts of cyclopentadiene or from dicyclopentadiene, e.g. by treatment with carbon monoxide and hydrogen followed by hydrogenation.  Polymerization accelerators such as cobalt naphthenate or octoate, zirconium octoate or tertiary amines, and dyestuffs, fillers and pigments may be included.  In the example the polyester is derived from fumaric acid, phthalic anhydride and a diol obtained from dicyclopentadiene, carbon monoxide and hydrogen, by esterification in the presence of trichlorethyl phosphorous acid ester and hydroquinone.  The compositions are air drying and gelatinize very quickly when applied as lacquers on wood, metal or glass, but have improved pot-life.  Specification 766,666 is referred to.

Title: Well drilling apparatus and method
IPC: E21B19/08
Filed: 1956-11-26
Abstract: 816,845. Automatic cable-tension control systems. MUD CONTROL LABORATORIES Inc. Nov. 26, 1956 [May 14, 1956], No. 36069/56. Class 38 (4). [Also in Groups XXI and XXXVIII] The tension in a cable supporting a well-drilling tool is reduced when it exceeds a pre-determined value in order to maintain the pressure of the tool on the well bottom, by sensing the tension as by passing the cable round a pressure-sensitive ring and releasing the cable reel for a predetermined time when the cable tension exceeds a predetermined value. As shown (Fig. 5), the distortion of the ring moves the slider 76 of a potentiometer 78 in a pre-set bridge circuit, the take-off voltage being applied through smoothing circuits to a D.C. amplifier 194 indicating on meter 196 the deviation in tension from the preset value, and to amplifier 236 and thence to pentode 240 which increase in drill pressure cuts off to operate alarm horn 268 and pneumatic valve 270 which prevents further paying-out of cable. The output of amplifier 236 is also fed to pentode 242 which increase in cable tension causes to conduct, closing switches 280 and 306, and thus bringing into operation multivibrator 282, which operates to close switch 308 and open air valve 318 for a period determined by the setting of resistor 300. The opening of this valve operates a pneumatic cylinder 84 which releases the brake on the cable reel, allowing cable to unwind and reduce cable tension; if cable tension is not reduced sufficiently in this period to open switches 280 and 306 the multivibrator will continue to operate and release the reel for a further period or periods. Potentiometer 168 is pre-set to a position representing the desired tool pressure, and is re-adjusted as further lengths of drill pipe are added since the desired cable tension depends on the total weight of drill and drill pipe less the desired drill pressure.

Title: Improvements in devices for operating land mines and the like by the passage of tanks or other heavy vehicles
IPC: B60P3/34
Filed: 1938-12-19
Abstract: 507,049. Military land mines; Bowden mechanism. SCHNEIDER & CIE. Dec. 19, 1938, No. 36940. Convention date, Feb. 16. Addition to 453,335. [Class 9 (ii)j. [Also in Group XXIV] .. The sheath of a sheathed-cable device associated with the firing mechanism of land 1 mine or the like as described in the parent Specification, comprises, from place to place, elongation control groups formed by the combination of beads of rather large diameter in. the form of biconvex lenses between the edges of which are disposed forcing rings of a ductile metal, such.as annealed aluminium. Means are also described for regulating the length of the sheath relatively to that of the cable. As shown in Fig. 1, the firing mechanism comprises a fuze, the head l of' which is screwed on the appliance 2 to be exploded and carries a fixed percussion cap 3 adapted to be struck at the moment of firing by a striker 5. The latter, which is normally secured by means of a shear pin 6, is acted on by a thrust spring 7 bearing on a fixed part 8 and also by a fork 9, the arms 10 of which pass freely through apertures 11 in the part 8. The end 12 of the deformable external sheath 13 surrounding the retaining cable 14 is applied against the fork 9, whilst the end 15 of the cable is secured by a flanged socket 16 to the part 8. In operation, when crushed by the passage of a tank, the sheath 13 undergoes elongation relatively to the cable 14 so that its end 12 pushes the fork 9 towards the interior of the fuze. The pin 6 is thereupon sheared and the striker 5 driven by the spring 7 against the percussion cap 3. The sheath, which comprises, in the vicinity of the fuze, a flexible part 17, is also formed with a series of beads 18, 19 with, from place to place, a group of beads 20 of large diameter having the form of biconvex lenses between the edges of which are disposed rings 21 of an extremely ductile metal. , The end 22 of the cable has an expanded form which prevents it from entering the interior of the last bead 23 of the sheath and, if desired, a flexible sheath element 24 maybe interposed between this bead and the other beads of the sheath. Fig 3 shows one means for adjusting the length of the sheath relatively to that of the cable in which there is provided between .the bead 23 and element 24. a bead 26 having a screw-threaded portion 27 adapted tu be screwed more or less into an internally screw-threaded sleeve on a further bead 25. According to a modification of this arrangement, Fig. 4 (out shown), the internal screw-thread is formed in the end, lenticular bead 20. According to a. further modification, Fig. 5, the adjustment is effected by means of a key 29 having the form of a fork, the arms 30 of which act as wedges between the end'- bead 23 and the preceding bead 31.
