Title: Improvements relating to cast iron
IPC: C22C37/04
Filed: 1949-03-17
Abstract: Magnesium is added to alloyed or unalloyed cast-iron, before the iron is cast, so that the casting contains 0.02-0.04 per cent Mg and substantially all the graphite is present in a more rounded and shorter form than ordinary flake graphite.  After addition of Mg the melt may be inoculated and cast shortly afterwards.  An example is given of the addition of Mg, and its retention in the resulting casting within the above range, to iron containing C 3.36 per cent, Si 1.8 per cent, Mn 0.39 per cent, Ni less than 0.1 per cent, S 0.008 per cent, P 0.039 per cent, Cr 0.04 per cent, Ti 0.03 per cent; Pb less than 0.002 per cent, Sn less than 0.01 per cent, V less than 0.01 per cent.  Mo less than 0.1 per cent, Cu 0.07 per cent, Mg less than 0.01 per cent, Sb and Te only very faint traces.  In general, Cr may be present up to 1 per cent, Mn up to say 2.5 per cent, Cu up to 3 per cent and Al and Ni may also be present.  Mg may be added as metal or as an alloy, e.g. with Ni or Cu, such as one containing 2-40 per cent Mg, or in elemental form with diluents which decrease the burning of the added metal. If added as an alloy, the alloy preferably has a density approaching or even exceeding that of the molten metal. Specification 630,070 is referred to.

Title: Improvements relating to magnetron oscillators and their associated output circuits
Inventor: DUNSMUIR ROBERT
IPC: H01J23/36
Filed: 1955-03-16
Abstract: 791,735. Magnetrons. BRITISH THOMSONHOUSTON CO., Ltd. Feb. 23, 1956 [March 16, 1955], No. 7701/55. Class 39(1). [Also in Group XL(b)] A magnetron output circuit is so arranged that on the commencement of a train of oscillations it presents the magnetron with a high ouput Q factor and thus allows a rapid build up of r.f. oscillation in the magnetron. When the build up of voltage has been completed a fraction of the output is reflected back to the magnetron by a suitably positioned reflector, e.g., a post 6, to effect a reduction in the Q factor thus enabling extraction of substantial r.f. power. The magnetron 1 is coupled to the output guide 7 by means of a tapered slot 4 whose width and degree of coupling to anode resonator 3 are adjusted to provide a high external Q factor for the system. The distance of the resonator 3 from the post 6 should correspond to an integral number n of half-wavelengths plus an amount which is less than an eighth wavelength. The value of n may be four times the number of cycles required for build up. A reflectionless window 5 provides a vacuum seal and is situated either beyond the post 6 or between the post and the magnetron at a point of minimum voltage of the standing wave pattern produced by the post. The invention may be applied to a co-axial line output system.

Abstract: 1486694 Antiskid braking systems SAAB-SCANIA AB 26 Feb 1975 [1 March 1974] 8058/75 Heading F2F In a method of regulating braking in an antiskid system which includes means for measuring wheel speed, a valve unit in the brakeline and an electronic control which responds to reference values of various parameters, the wheel deceleration is determined and a signal representing wheel acceleration is compared with a signal representing actual braking pressure increase to determine the amount of braking pressure increase required over the braking pressure used in order to obtain optimum braking between wheel and road surface and during the subsequent braking pressure increase the value there of is increased to that determined by the maximum wheel acceleration. Each wheel speed is determined by means of a transducer 1 connected to a pulse shaper 5 and a valve 6 mounted in the brake line is connected to a valve regulating module 2 connected in turn to a pressure increase calculating module 3, a central module 4 providing control signals. The output from module 5 is fed within each module 3 to a wheel acceleration calculating circuit 9, a wheel retardation calculating circuit 10 and a circuit 11 for detecting wheel lag, retardation signals being applied to a comparator 17 which compares the signal with a predetermined reference signal from module 4. When the greatest permitted retardation is exceeded the comparator 17 gives a signal which causes reduction of braking pressure by regulating the valve unit 6. A comparator 18 senses heavily increased retardation, comparators 17, 18 being connected across a diode 20 blocking comparator 18 from causing continuous pressure reduction when there is no signal from comparator 17. Circuit 11 comprises a comparator which compares an instantaneous speed signal from module 5 with a reference signal from module 4 and the output is supplied to an output of comparator 7. The valve unit 6 has an inlet valve 27 and an outlet valve 28 operated by drive circuits 31, 32.
