Title: An improved process and apparatus for grinding the flanks of teeth of helically toothed spur wheels
IPC: B23F5/06
Filed: 1921-03-31
Abstract: 160,832. Fleischmann, N. March 31, 1920, [Convention date]. Gear-wheels, grinding and trueing teeth of.- The tooth-flanks of spur-wheels having previously cut involute helical teeth are ground to the mathematically exact shape of the involute surface, which is generated by unrolling from the base-circle cylinder helical line of the toothed wheel in such a manner that the helical surface is generated as the surface enveloped by all its tangential planes, by means of the plane surface of a grinding-disc, the arrangements being such that the operative plane of the disc constitutes at every instant the tangential plane for the time being of the involute helical surface. The previously cut helical wheel R, Fig. 3, is mounted for rotation about its axis, and a grinding-wheel L, driven by a motor M, is carried by a slide S movable parallel to the axis of the wheel R. The grinding-wheel is set to the correct angle and position and is traversed along the wheel R at a speed corresponding to the pitch of the screwthread formed by the teeth of the wheel, the wheel R being indexed after each passage of the grinding-wheel to present a new tooth thereto. Each tooth may be finished by one passage of the grinding-wheel, or, as in the case of wheels of large dimensions, a portion only of all the teeth may be ground, the process being repeated after adjustment of the grinding-wheel in its own plane and for wear. Both flanks of the teeth may be ground at the same time by the use of two parallel grinding- wheels.

Title: Method of pre-carburization of drill steel
IPC: C23C8/80
Filed: 1960-03-21
Abstract: 944,572. Making drills; altering physical properties; working at specified temperatures. T. W. WLODEK. March 21, 1960 [Aug. 24, 1959], No. 9831/60. Headings B3A and B3V. A process for producing a hardened hollow steel member comprises hardening one of the surfaces of a hollow steel billet of at least four inches in thickness having a hole therein of at least one inch diameter, the hardening being effected at an elevated temperature, e.g. 1500‹ to 2300‹ F. in the presence of carbon and/or other diffusion hardening element until a hardened layer of from 0.015 to 0.080 inch thick is formed and subjecting said member to mechanical deformation under pressure at a temperature of 1500‹ to 2100‹ F. to effect considerable reduction in cross-sectional area to produce a hollow steel member such as hollow drill steel, thereby effecting grain and structure refinement and improving the physical properties of the hardened surface layer. The hardened surface may be further treated by pressing shallow grooves at spaced intervals on said surface, said grooves being between one thousandth and one sixteenth of an inch in depth. This treatment is carred out at room temperature or below the recrystallization temperature of the metal. It may also be carried out above the recrystallization temperature provided it is followed by over rolling with a smooth roller at a temperature below the recrystallization temperature. The pre-diffusion impregnation treatment by, for example, chromium, molybdenum, cobalt, columnium, titanium, boron, silicon, aluminium, uranium, vanadium, tungsten, nickel and their compounds, provides a surface alloy layer which is refined by the final plastic deformation. After completion of the pre-diffusion treatment the billet is cooled and cleaned and an austenitic manganese steel rod is inserted into the centre hole of the billet prior to the final rolling operation. Specific examples of the process are given in the Specification. Specification 815,958 is referred to.

Abstract: 931,569. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 5, 1962 [March 17, 1961], No. 9853/61. Class 37. In a controlled rectifier of the PNPN type, the concentration of impurity material in the region of the device serving as the emitter is at least 5 x 10<SP>19</SP> atoms/cc. It is stated that by using such a high concentration, the thickness of the adjacent regions can be increased thereby allowing greater manufacturing tolerances, a reduction of the switching current and an increase of the breakdown voltage. A PNP structure of silicon (or Ge) is heated to 1300‹ C. (or 800‹ C.) in an inert atmosphere and P, As or Sb is then diffused in to one of the P-type surfaces to form a highly doped (up to 30 x 10<SP>19</SP> atoms/cc.) N- type zone. Alternatively, using a NPN device, boron may be diffused in. If an alloying technique is used, suitable impurity materials for the first device would be Au-P or Au-As and for the NPN device, Al-B or B.

Title: Improved Means for Raising the Tools of Ploughs and other Agricultural Implements.
Inventor: CORNELL ARCHER
IPC: A01B63/16
Filed: 1918-06-17
Abstract: 128,380. Cornell, A. June 17, 1918. Adjusting parts of implements; frames for implements; ploughs; cultivators; harrows; seed distributors. - To enable a plough, harrow, seedplanter, cultivator, trencher, or like agricultural implement to be raised from the operative position on to its road wheels, these wheels 7, 8 are mounted on arms 6 on a cranked axle 5 which is connected by a link 20 with a second cranked member 14 adapted to be operated by a hand-lever 24. The hand-lever 24 is pivoted on one of the ends 15 of the member 14 alongside a sector 25 which is rigidly secured to the member. The sector is provided with cut-away portions 27, 28 adapted to be engaged by a projection 32 on a spring-pressed pawl 30 and also with a stop 38 which co-operates with a catch 35 mounted on the lever 24 and operated by a releasing-lever 33. During the operation of the implement, the wheels are lifted and the lever and sector are in the position shown in Fig. 4. To raise the implement on its wheels, the releasing-lever 33 is operated, lifting the catch 35 and simultaneously by a projection 42 lifting the pawl 30. The weight of the wheels then causes the cranked axle 5 to turn until the wheels engage the ground when the animal-draught, or other tractive power causes the machine to be lifted on them. Stops limit this lifting movement. The sector 25 is swung forward by the movement of the axle 5 until the @ away part 27 is engaged by the pawl 30, thus locking the axle, To lower the implement, the pawl 30 is lifted to release the sector by means of the lever 33 and the hand-lever 24 is pushed forwards until the catch 35 slips over and engages the stop 38. The hand-lever is then drawn back, moving the sector and the axle 5 until the pawl 30 drops into the. recess 28 and locks the wheels in their raised position. The wheels are provided with projections 49 as shown, which act as skid-preventers and co-operate with arms 46 in lifting the implement from the ground. The arms 46, which are fixed upon rotatable shafts 45, are each formed by two parallel plates kept apart by distance-pieces and carrying between them a brake block 48. These plates are adapted to engage the laterally-projecting parts of the projection 49 when the wheels reach the ground, and through this connexion with the wheels to raise the main frame, the plates being shaped to slip off the projections as the wheels reach their final position. The arms 46 are normally maintained in their operative position by weights 52 and springs 53. A hand-lever 58 can be operated to press the brake blocks 48 against the wheels when these are in use.
