Title: Improvements in indicating apparatus for combined coarse and fine electrical indications
IPC: G08C25/00
Filed: 1964-04-09
Abstract: 1,007,047. Selective signalling. WIENER SCHWACHSTROMWERKE GESELLSCHAFT m.b.H. April 9, 1963 [May 15, 1962], No. 14133/63. Heading G4H. In order to digitize the positions of two members S, Z, coupled by continuous gearing (not shown) the more significant member is sensed by lead and lag contacts K1-K5 and K1<SP>1</SP>-K5<SP>1</SP>, and the arrangement is characterized in that the lead and lag sensing contacts can be connected in associated pairs in dependence upon the position of the lesser significant member Z so as to avoid transitional carry errors. In operation the members S, Z are allowed to move and to come to rest. A contact T1 is then closed causing pulses representative of the angular position of the member Z to be entered into a first counter ZW1. This counter, if more than half full, energizes a relay R and thus connects the associated pairs of sensing contacts. Contact T2 is then closed causing-by means of progressive delays V2- V5 and an OR gate G-pulses equal in number to the number of steps of the member S sensed by operative contacts to be entered into a counter ZW2.

Title: Improvements in or relating to boost controls for internal combustion engines
IPC: F02D11/06
Filed: 1937-05-21
Abstract: 501,045. Fluid-pressure servomotorcontrol systems. SOC. GENERALE DES CARBURATEURS ZENITH. May 21, 1937, No. 14218. Convention date, May 22, 1936. Addition to 495,307. [Class 135] In the boost control device described in the parent Specification, the chamber 19 which contains the manometric element 21 and communicates by a passage 20 with the intake manifold 1 on the delivery side of a device, such as the throttle 4, for regulating the quantity of air or mixture admitted to the engine, communicates independently of the means for varying the datum of the boost control with the atmosphere or with the suction side of the regulating device 4 by an air pipe 92, both the passage' 20 and the air pipe having a calibrated restriction 91, 94, respectively. The air pipe may contain a check valve 95 and this may be spring-loaded as shown in Fig. 2. Bysuitable choice of the restrictions 91, 94 the maximum induction pressure can be rendered independent of the altitude up to the rated height. Alternatively it can be made to increase or decrease with the altitude to suit the type of engine used. The restrictions may be such that the valve 95 does not open until a predetermined height is reached so that the maximum induction pressure decreases up to this height thereafter remains constant. The predetermined height may be adjusted by means of the spring 96. The valve 95 is dispensed with when the supercharger 2 is not used. The invention is applicable to any of the boost controls described in the parent Specification. Fig. 1 shows a carburettor throttle valve 4 operated jointly by the boost control device 7 and the pilot's lever 5 similar to the arrangement shown in Fig. 1 of the parent Specification. The particular form of boost control is shown in Fig. 2, and is similar to that shown in Fig. 5 of the parent Specification, in which the datum of the boost control is adjusted by the power member 29 by adjustment of a loading spring 70 which acts on the capsule 21 through the bell crank 67 and the pilot valve 34. The pilot's lever in this case produces a progressive closure of the throttle 4. Where the pilot's lever operates on a separate throttle on the inlet side of the throttle 4, the air pipe 92 opens on the inlet side of both throttles. Fig. 5 shows a boost control device similar to that shown in Fig. 8 of the parent Specification in which the power member 29 operates on a tapered leak-off valve 88 to vary the datum of the boost control. In this case, the pipe 86 opens into the intake manifold between the throttle and the supercharger. Where a second throttle operated by the pilot's lever is used, the pipe 86 opens between the throttles and in this case the valve is reversely tapered. The provision of the pipe 92 does not affect the variation of the rated induction pressure with engine speed and hence the apparatus may be made responsive to changes in both engine speed and altitude. The separate throttle valve operated by the pilot may be on either side of the supercharger.

Filed: 1973-03-28
Abstract: 1425658 Cathode-ray tube circuits; transistor amplifying circuits SONY CORP 28 March 1973 [31 March 1972 (2)] 14871/73 Headings H3T and H4T In a dynamic convergence circuit for a plural beam (colour) cathode-ray tube the convergence coils 13 (Fig. 1) are connected in series between a D.C. power supply source at terminal 4 and the horizontal output winding 3 of a horizontal deflection circuit including driving means 1, switching transistor 2, damper diode 5, capacitor 6 and horizontal deflection coil 7 and compensation capacitor 8. In operation, each horizontal pulse is integrated by the winding 3 and a capacitor 11 so that a sawtooth voltage is produced across the convergence coils 13 and results in a current of, generally, parabolic waveform ic. (Fig. 2) in the latter, which provides the required convergence in the horizontal direction. The "tilt" of the waveform may be adjusted (dotted curve Fig. 2) by means of resistor 12 and the amplitude by means of resistor 14. This arrangement may be modified as shown at the left-hand side of Fig. 3 which in addition, provides means for effecting a vertical frequency parabolic modulation to produce convergence correction in the vertical direction. The latter correction is effected by connecting the convergence coils 13 via an inductance 15, which has a high impedance for the horizontal frequency, to the vertical deflection circuit comprising a driver 16 connected via transistors 17 and 18 to a single ended push-pull output stage (SEPP) formed by transistors 20, 21 which supply a sawtooth current waveform to the vertical deflection coils 22 so that a parabolic waveform of vertical frequency is developed at the junction a of capacitors 23, 24 to which the inductance 15 is connected. The composite correction waveform then has the shape shown in Fig. 4. In a modification of this arrangement the inductance 15 is connected to the emitter of transistor 21 and a separate voltage source is connected to the deflection coils 22 (Fig. 5, not shown). Fig. 6, shows a further arrangement in which a vertical frequency parabolic waveform, already available for pincushion distortion correction, is introduced via transistor 28a. Instead of connecting the convergence circuit in the emitter circuit of transistor 2 it may be connected in the collector circuit (Fig. 7, not shown).

Abstract: 246,434. Soc. des Etablissements Ducretet. Jan. 24, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Indicators, applications of.-A thermionic valve with two grids is utilized to generate oscillatory or alternating current and this current is combined with a second current for indicating when an alternator is generating a standard frequency, and for other purposes. As shown in Fig. 3, oscillations received in the aerial 13 are applied across the grid 4 and filament 2 of the valve 1, and local oscillations are generated by a coupling 8, 9 between the plate coil 8 and the tuned circuit 9, 10 connected between the filament and the second grid 3. The beat or resultant frequency is transferred by a coupling 11, 12 to an amplifier 18. For indicating synchronism of an alternator, the alternator potentials are applied to the circuit 2, 4 and the plate circuit includes an indicator, the pointer of which vibrates at the difference frequency, but is stationary when the aerial and the alternator frequency is in exact agreement with that of the oscillator, as determined by the tuned circuit 9, 10. The aerial and the coupling 11, 12 are omitted. Instead of using a reaction coupling, oscillations may be applied from an external source to the grid 3. Filter circuits may be arranged to select the desired frequency component from the complex output current.

Title: Separation of phosphorus from carbonaceous material
IPC: C01B25/047
Filed: 1961-04-26
Abstract: Carbon-containing impurity is removed from a mass of elemental phosphorus by vaporizing the phosphorus and subjecting the vapours to above 500 DEG C. in the presence of inert, refractory solid contact material for a period of time sufficient to cause the carbon to deposit upon the contact material and separately recovering the phosphorus in an inert atmosphere.  The carbonaceous material may be carbon such as coke or hydrocarbons such as high molecular weight, e.g. at least 150, tarry, carbonaceous or bituminous refractory hydrocarbons such as aromatic hydrocarbons containing at least 12 C. atoms/molecule.  The solid inert refractory bodies may be quartz, SiO2 or high melting point ceramics such as ZrO2, to provide a surface for the deposition of carbon and other impurities, e.g. B, Ni, Cu, Si, Sb, Mg and Fe.  The inert bodies may also be catalysts for the cracking of hydrocarbons, e.g. Al2O3 and alumino-silicate clays, and may be regenerated by burning off the carbon at elevated temperatures in a free-O2 containing gas, e.g. air or O2.  In an example, yellow phosphorus containing 0,04-0,4% C is vaporized at 0,1-100 mm.  Hg pressure at 90 DEG -300 DEG C. and is led through a quartz tube filled with quartz helices at, e.g. 800 DEG -1200 DEG C. to decompose any PH3 formed, for 0,1-10 sec. contact time. The phosphorus is then condensed in a receiver in a stream of inert gas, e.g. N2 or He, A or Ne.  The heat treatment of the phosphorus may be repeated to reduce its C content from not more than 4-5 ppm. to 0,1 ppm. or less.
