Abstract: 827,257. Rolling. MICHIGAN TOOL CO. Aug. 29, 1957 [Sept. 6, 1956], No. 27290/57. Class 83 (4). A method of forming teeth or other radial projections on the surface of a cylindrical member comprises heating a portion only of the surface intermediate the ends of the section upon which the projections are to be formed and thereafter forcing a succession of tool teeth radially into the surface of the section. The work is heated by an annular induction element 88 which heats a zone 86 to a semiplastic state while the remaining portions 101 and 103 of the workpiece are maintained at a sub-critical temperature. The workpiece 34 is then mounted between adjustable centres 36, 40 and subjected to the action of a pair of toothed platens 30, 32. The working faces of the platens 89, 90 are made to converge as the rolling operation proceeds by tapering each tool uniformly or by inclinding the pitch lines of the tool teeth or by gradually increasing the height of the tool teeth while holding the pitch line level. The platens are located in holders 26, 28 respectively and are moved simultaneously in opposite directions by pressure cylinders 50, 52 operated by pump 85 and control valve 84 (not shown), which cause pressure to be exerted on the pistons of the cylinders in the required direction.

IPC: G01N25/00
Filed: 1963-07-15
Abstract: 1,057,135. Apparatus for analyzing materials; measuring expansion photo-electrically. METRIMPEX MAGYAR MUSZERIPARI KULKERESKEDELMI VALLALAT. July 15, 1963, No.27964/63. Headings G1A and G1N. The behaviour of a material when heated is recorded by mounting a specimen 1, compressed of the material to be tested, in an oven 18 with an inert body 2. The specimen is carried in a crucible supported on balance beam 23 and the top of the specimen bears against an abutment 22 so that changes in the length of the specimen (the dilatation) deflect beam 23 and so deflect a light beam from source 25 falling on recording drum 27. The output from a coil 13 suspended from beam 23 between magnets 14 is indicative of the rate of dilatation. The specimen 1 and inert body 2 have thermocouples inserted therein, connected to galvanometer 30, 31, one of which records the temperature of specimen 1 while the other records the difference in temperature between bodies 1 and 2, which is stated to be a function of the change of enthalpy of specimen 1. In a modification the weight and rate of change of weight are recorded also. The weight of the specimen is transmitted to beam 23 by rod 20 Fig. 5 while the expansion of the specimen causes movement of a cylinder 32 connected to a stirrup 33 resting on the specimen. Such movement is detected by movement of a pair of diaphragms 34, 35 in front of a photo-cell 36. The output is recorded directly to indicate the dilatation and is also differentiated to indicate the rate of dilatation. Movements of the balance beam are used to indicate the weight and rate of change of weight. Thermocouples are again provided. In another embodiment a balance is not used, the specimen 1 and inert body 2 being arranged in a tube and resting against partitions therein. Dilatation of the specimen operates a mechanical linkage which tilts a mirror to deflect a light beam. The linkage also moves a coil in a magnetic field for recording the rate of dilatation. In the arrangement shown in Fig. 5 the diaphragms and photo-cell may be replaced by a pair of capacitor plates, one on each tube 20, 32; or by a differential capacitor arrangement; or by a magnetic core and coils attached to the tubes.
