Title: Method and apparatus for rolling external and internal profiles on cylindrical workpieces or in cylindrical bores
IPC: B21H3/00
Filed: 1952-02-19
Abstract: 743,977. Rolling. KRUSE, H., and FETTE, C., [trading as FETTE PRAZISIONWERKZEUG-FABRIK, W.]. Feb. 19, 1952, No. 4354/52. Class 83 (4). In a method of rolling internal or external profiles by means of profile rolls arranged around a common axis, the rolls and work being relatively rotated, the axes of the rolls are inclined to the axis of the work to provide axial feed and the rolls have helical profiles arranged at angles suitable to provide the required profile on the work. In examples rolls R, Fig. 1, inclined at angle b to the work W to provide a feed motion roll helical threads at a pitch angle c dependent upon the angle a of the helical profile of rolls R and the angle b. In particular examples the angle c may be such that the profiles are left- or right-hand single or multi-start threads, annular grooves W2, Fig. 4, axially parallel or helical rifling for twist drills, reamers, spur gear wheels, &c. Combinations of different profiles may also be rolled simultaneously. In a particular example in which a workpiece W6, Fig. 8, is engaged by a number of rolls R5 arranged around the work axis, the rolls are synchronized by initial engagement with a head K having the required threaded profile and rotated at the same speed as the work holder P through gears Z1-Z4 and shaft W7. Apparatus suitable for supporting the rolls and providing automatic release from the work is described in Specification 705,754.

Abstract: 1,125,676. Photo-electric measurement of high voltage systems. BROWN BOVERI & CO. Ltd. Feb.1, 1967 [Feb.3, 1966], No.4909/67. Headings G1A and G1U. [Also in Division G2| Measured values are transmitted from a region of high potential to a region of low potential by causing the measured value to modulate the position of a mirror which modulates interferometrically a monochromatic light beam emitted from and received at the region of low potential. Light from a gas laser is transmitted by an optical fibre 10 to an interferometer 7 in the vicinity of a high voltage conductor the current wherein is to be measured. The light beam is split by a Koesters prism 19 to provide beams which are reflected by mirrors 16 and 17 on to a fixed mirror 21, which causes the beam to retrace its path. The portion of the output of a transducer measuring the conductor current is picked off by a temperature variable potentiometer, integrated and applied to electrostrictive converters 14, 15 to modulate the position  of the mirrors 16, 17 in antiphase to produce a pulsating light intensity in the divider plane 20 of the prism 19. A 90 degree phase plate 23 covers half of the beam to mirror 16, so that the pulsation of two halves of the combined beam are 90 degrees out of phase. These halves are transmitted by optical fibres 11 to photo-detectors 26, 27, Fig.4. The outputs of detectors 26 and 27 are mixed at 30 and 31 with carrier signals in quadrature from an oscillator 28. The carrier components are removed at 32 and 33 and the modulated signals added at 34 to give a signal which is frequency modulated with the measured current signal. This signal is detected by an f. m. demodulator 38 and fed to an indicator 39 or recorder 40.

Pattern-plates 7, rotatable in bearings 6 and supporting patterns 8, are carried on a rotary, step-by-step table, through an electric heating- oven 10, to a station E where cured moulds are ejected by pins actuated by a pedal-operated plunger beneath the table, thence to a station F where they are sprayed with parting fluid, and an open-ended flask 17 is fitted. At a station G, a predetermined quantity of mould-mix is deposited in the flask from a hopper 19. The station H is idle for allowing the shell to form, and at station I the pattern is inverted, allowing the excess mix to fall into a receptacle. The flask may fall off at this stage and the pattern be returned to its normal position, or both these operations may be performed at station J. The pattern-plate and shell then pass through the oven for curing the shell. The oven may be divided into several thermostatically-controlled zones.
