Title: An electromagnetic following device
IPC: B23Q35/128
Filed: 1958-11-26
Abstract: 898,946. Electric copying machines. VYSKUMNY USTAV PRE MECHANIZACIU A AUTOMATIZACIU. Nov. 26, 1958 [April 25, 1958], No. 38113/58. Class 38 (6). [Also in Group XXXVI] An electro-erosive cutter is automatically guided to cut a predetermined profile by signals from a photo-cell which is scanning a drawing, and the speed of movement is controlled in accordance with the magnitude of the erosion current. An undisclosed photo-electric scanner is said to produce two sets of pulses 15, 19, phase modulated in accordance with deviations from the drawing. The pulses are applied to the grids of a double triode 11 forming a cathode follower with two inputs and a common output. The triodes are, in an undisclosed manner, biased to cut-off; but this bias is opposed by two voltages applied at 23, 24 and derived from an undisclosed source which is responsive to the magnitude of the erosion current. The output of the valve 11 thus consists of pulses modulated in phase for directional control and in amplitude for speed control. The pulses are given a sinusoidal shape by a tuned circuit 33, and are applied via a power amplifier 27 to two electromechanical discriminators 28, 29 which control hydraulic servomotors for the X and Y axis movements of the cutter. The discriminators (see Group XXXVI) consist of an E-shaped iron core carrying a coil excited from an A.C. reference source of the same frequency as the repetition frequency of the control pulses, and a coil carrying the control pulses moving axially within the air gap of the core. The axial displacement of the moving coil is thus proportional to the phase and amplitude of the pulse signal relative to the reference. By energizing the two reference coils 90 degrees out of phase, the control signals can be resolved along the X and Y axes. Reference has been directed by the Comptroller to Specification 824,001.

Abstract: 1,142,228. Iron nitride. IMPERIAL CHEMICAL INDUSTRIES Ltd. 10 Aug., 1967 [31 Aug., 1966], No. 38859/66. Heading C1A. Iron nitride is produced by nitriding iron, and before 100% conversion to nitride is achieved, the residual iron is oxidized with a free oxygen-containing gas to the oxide at a temperature below that at which substantial decomposition of the iron nitride occurs. The iron may be obtained by reduction of iron oxide, and may be in the form of powder, filings or pellets. Preferably, the iron is reduced to the nitride with ammonia, at between 350‹ and 500‹ C. until less than 2% of the iron remains unconverted. The product is then cooled to the ambient temperature in an inert atmosphere, e.g. nitrogen, and then oxidized with (for example) air, passed over the product at such a rate that the temperature remains below 50‹ C. The process may be applied to the method of making iron nitride described in Specification 1,135,812.
