Title: Improvements in or relating to apparatus for rolling wheel-sets
IPC: B24B39/04
Filed: 1966-01-21
Abstract: 1,104,901. Rolling wheels. WILHELM HEGENSCHEIDT KOMM. GES. 21 Jan., 1966 [25 Jan., 1965; 1 Feb., 1965], No. 2908/66. Heading B3M. Apparatus for smoothing and form rolling the tread surface of the wheel rim of a railway wheel set 6 includes, for each wheel 9, a head 15 which carries rolls 13 and 22, Fig. 3, and which is urged into contact with the wheel rim by an hydraulic cylinder 4. The cylinder is positioned on the cross beam 3 of a housing 2, while the wheel set 6 is supported on pairs of driven rollers 10, 10<SP>1</SP>. Each head is pivoted at 23 to the piston rod of cylinder 4 and includes a pair of plates between which the rolls 22 and 13 are mounted, the roll 13 being supported in a casing 14 which is pivoted at 16 to the plates. During rolling the fluid flow to cylinder 4 is gradually decreased, to cause the head 15 to rise and pivot anticlockwise about the point 23. The pressure in cylinder 18 remains constant, resulting in the head being traversed across the wheel rim with the inclination of the roll 13 progressively changing. The roll 22 serves as a support for the rim and prevents axial forces being transmitted to the wheel set. Each head is provided with a rigid arm extend ing rearwardly to a support of adjustable height, thus enabling wheels of different diameters to be readily accommodated for rolling.

Title: Method and apparatus for tensioning strip
IPC: B21B37/00
Filed: 1972-01-21
Abstract: 1408573 Rolling mills WEAN UNITED Inc 21 Dec 1972 [21 Jan 1972] 2934/72 Heading B3M [Also in Division G3] Tension in a strip passing between two stations, e.g. adjacent stands 11, 12 in a cold strip rolling mill, is controlled by operation of a tensioning device in responce to a tension measuring device, the two devices being arranged at two separate points between the stands. The object is to achieve a more rapid response than is given by the conventional method of adjusting the speed of (high inertia) rolls. Measurement is by a strain gauge 34 sensitive to the movement of a pivoted arm 30 carrying a roller 29. The signal from this is compared with a reference 45 in amplifier 44 and any error adjusts the hydraulic loading applied to a second pivoted arm 24 having a roller 25. Further rollers 37, 40 above the strip deflect it to ensure contact with the measuring and tensioning rollers 29, 25. To maintain the tensioning arm within a desired range it is connected to a non-linear potentiometer 51 whose output controls the speed of the rolls 16 in the leading stand 11. Over the normal range this has virtually no effect, but excessive movement of arm 24 causes progressively greater alteration to the speed.

Filed: 1965-01-27
Abstract: 1,095,235. Ionization manometers. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN. Jan. 27, 1965, No. 3596/65. Heading HID. The linear measuring range of a Bayard- Alipert type hot cathode manometer tube is increased towards higher pressures by maintaining the grid at a lower potential than the cathode so that it functions as an ion collector whilst a screening layer on the inner wall of the tube or a metal sleeve in the vicinity of said inner wall is at a higher potential than the cathode and functions as the electron collector. The conventional axial wire ion collector is connected to the grid. The screening layer may be of tin oxide. The arrangement is stated to provide a linear measuring range in helium from 10<SP>-10</SP> to 1 mm. Hg., which range may be further extended towards higher pressures by reducing the internal diameter of the tube, e.g. from 50 mm. to 40 mm.

Title: Improvements in and relating to friction gear for power vehicles
IPC: B60K17/06
Filed: 1924-02-12
Abstract: 222,372. Kleinschmidt, C. G. Feb. 12, 1924. Variable - speed a n d reversing gearing comprises a driving friction cone with steps 12, 13, 14, Fig. 5, with which a hollow swinging cone 18 is adapted to engage alternatively. The rocking pivot 20 of the hollow cone, the apex of the hollow cone, and the apex of the step of the solid cone in action are coincident for each speed. To effect this, the transmission shaft 21 beyond the joint 20 is adapted to slide within a non-sliding driven shaft 22. The hollow cone is supported in a yoke 29, Fig. 4, which slides between a pair of levers 28 pivoted at 27. Thus the two different movements which have to be imparted to the hollow cone in changing speed are effected by pull-rods 33, 34, respectively. Frictional pressure is maintained by a spring 43 acting through a link 41 on a lever 40 at the end remote from the rod 34, the lever being medially pivoted on the yoke 29. In changing speed, the thrust of the spring 43 is neutralized by a thrust on a pedal communicated through a rod 44. The change is then effected by a hand lever. The lever 40 has two fulcrums 38, 39, Fig. 5, upon the end 35 of the rod 34 about which the thrust of the spring 43 acts alternatively for the two geared drives, the low-speed being preferably a one-to-one clutch drive. This is to produce the greatest frictional pressure when the smallest step 14 is acting. As applied to a motor-vehicle, the gearing is arranged transversely of the chassis and reversed driving is effected by a friction pinion adapted to engage the outer periphery 54<1> of the hollow cone.
