Patent GB-822105-A (GB)
Title: Improvements in or relating to level-indicating gauges operated by radiation
IPC: G01N23/08
Filed: 1957-07-18
Abstract: 822,105. Photo-electric level control. LANDIS & GYR A.G. July 18, 1957 [July 18, 1956], No. 22810/57. Class 40 (3). [Also in Group XXXV] In a gauge for indicating the level of a liquid or pourable solid by the use of a radiation source and counter, for example on opposite sides of a container in the region of the desired level, the output of the counter Z is applied through a R-C coupling Rg-Cg producing a voltage proportional to the mean frequency of the counter pulses to a differential amplifier comprising a long-tailed pair E1, E2 of triodes, the anodes being connected through resistors R3-R6 to the starting electrodes of two glow-discharge tubes GR1, GR2, which fire the tubes when they are sufficiently negative, the anodes of the tubes being fed with A.C. so that they are extinguished during the negative halfcycles. Potentiometer R12 is adjusted so that the anode currents of E1 and E2 are equal for the desired liquid level, and R11 allows adjustment of the total cathode current and hence of the change in level necessary to reduce the current in either E1 or E2 sufficiently to extinguish the corresponding glow-discharge tube. Relays A, B in the anode circuits of the tubes may operate control apparatus for the liquid level, or alarm circuits. In the case of failure of the supply or of the triodes E1, E2, both tubes GR1, GR2 will be extinguished; this "fault" condition may also be indicated by extra contacts on relays A and B arranged in a series circuit. Failure of the counter Z may be arranged to achieve the " fault " condition by provision of glow tubes G1, G2; when the signal from Z falls to zero an abnormally low grid potential of E1 and hence an abnormally high anode potential causes G1 to fire and raise the starter electrode potential of GR2, hence again extinguishing both GR1 and GR2, and G2 acts similarly on short circuit of the conductors of Z.

Title: Improvements in or relating to smoothing arrangements for power supply systems
IPC: H02M1/15
Filed: 1947-08-25
Abstract: 634,819. Smoothing direct currents; automatic control systems. STANDARD TELEPHONES & CABLES, Ltd., MOODY, N. F., and HOWELL, W. D. Aug. 25, 1947, No. 23433. [Classes 38 (ii) and 38 (iv)] Ripple in a D.C. system is stabilized or suppressed by an arrangement in which the ripple derived from the system is amplified and fed back into the system through a matching transformer in counterphase to the existing ripple. The output from full-wave rectifiers W1 and W2, is smoothed first by inductance L1 and capacitor C1, and then by feeding into the line supplying load RL, through transformer T1, the anode current of valve V1. the A.C. component of which is the amplified ripple across the load RL, which ripple is fed through capacitor C2 to the grid g1 The output ripple is thus stabilized at a low value. The amplified ripple may be fed back into the circuit including C1, to cancel the current through that capacitor, Fig. 3 (not shown). The polarizing effect of the D.C. component of the current in the transformer primary winding may be nullified by replacing valve V1 by two valves connected in push-pull with their anodes connected to opposite ends of the transformer primary winding, the centre tap of which is connected to line to provide anode potential, Fig. 4 (not shown). In Fig. 5, a second valve V2 is fed from valve V1, whereby the amplified ripple is reversed in phase. So that this may oppose the ripple in the line, one transformer winding is reversed and the polarizing effects of the D.C. currents in the transformer windings, cancel. By taking the ripple signal for the grid of valve V1 from the centre point of the transformer primary winding, or of resistances R3, R4 connected across it as shown in Fig. 6, the ripple across load RL may be completely suppressed. If the D.C. line voltages are positive and negative with an intermediate earth point, the polarizing effects may be reduced by connecting the transformer primary winding to the positive line to provide anode potential and feeding the amplified ripple to the transformer secondary winding in the negative line, Fig. 7 (not shown).

[Class 135.] In a pressure regulator of the kind described in Specification 5093/08, [Class 135, Valves &c.], in which the end of a conduit connecting a closed chamber 9, as shown in the Figure beneath the regulating membrane 7 with a lateral enlargement of the outlet chamber 2 is subject to suction action, so that an increased gas pressure results in an increased flow, the valve plate 3 and the walls of the outlet chamber are formed so that the flow of gas over the end of the connecting conduit 8 is substantially free from eddies. In one form of the invention the conduit 8 itself terminates in the enlargement of the chamber 2 and has a nozzle of trumpet or cylindrical form positioned so as to be approximately parallel to the path of flow. In another form, the conduit 8 terminates in an annular recess in the walls of the chamber 2, the edge of the recess nearer the valve plate 3 projecting farther into the chamber 2 than the other edge so as to augment the suction action. This recess may extend only partly round the chamber 2. In a third form, shown particularly in the Figure, the conduit 8 ends in a bore 20 penetrating the valve body and provided with a nozzle 21 having a throughpassage and a slot 22 arranged obliquely thereto. The rear end of the nozzle 21 has a positioning slot 24 parallel to or at right-angles to the slot 22 and the abutment face 25 is at a known distance from the valve spindle so that the nozzle 21 may be accurately positioned. The eddy-free passage of the gas is assisted by arranging that the distance of the valve pla e 3 from its seat 4 is greater on the side adjacent the nozzle 21, equally eccentrically arranged eyes 27, 28 on the plate 3 and spindle 5 serving this purpose. The plate 3 and spindle 5 are coaxial when the former is closed. In all the constructions the usual equalization membrane 6 is provided and is connected to the spindle 5. There is a venting nozzle 12 for the chamber 11. Alternative to the nozzle 12, a device which closes the connection between the chamber 11 and the atmosphere if the membrane 7 should leak, may be used. Several conduits 8 may be arranged between the chambers 9, 2.

Filed: 1973-05-17
Abstract: 1413718 Dividing SIEMENS AG 17 May 1973 [18 May 1972] 23675/73 Heading G4A An arrangement for dividing a number by three, six, and nine includes an adding means for forming successive sums of digits S r  where until a value of S # # is produced, means for comparing the value of S with three, six, and anine to determine whether N is divisible by the corresponding number, a further adding means to form a value m where where [10<SP>i</SP>/#] is the next integer below 10<SP>i</SP>/# and qi, 1  is the digit value of the decade 10<SP>1</SP> in a sum qi where q 1  = a 1  + a 0  and for i = 2 or more, and means to produce from m and S the quotients N/3, N/6, and N/# in dependence on whether N is divisible by 3, 6, and #. General.-Given a decimal number N, say 61038, the first sum S 1  = 6+1+0+3+8 = 18 and the second sum S 2  = 1+8 = #. Since S = #, N is divisible by #. The sums q are given by Thus m is given by the final one being the only non-zero value of qi, 1  (from q 1 ). Thus The quotients N/3, and N/6 are given by N/3 = 3m+S/3 and N/6 = 1/2.N/3. Apparatus.-A three digit decimal number N in BCD form is fed to an adder 1. The tens and units digits are added and the output fed to a further adder having a second input energized by a logic network to produce the appropriate BCD filler digit. A second adder then adds the result to the hundreds digit of N. The result is compared at 2 with 3, 6, and # to determine whether N is divisible by 3, 6, and #. The value m is formed at 3, circuits 4 and 6 adding 1, 2, and 3 as appropriate for the algorithms for N/#, N/6, and N/3, and circuit forming 3n by the addition m + 2n, 2n being formed by left shifting m. Circuit 7 checks whether N/3 is even and hence divisible by two to form N/6 at 8 by right shifting. The arrangement is said to be of use in calculations involving weight, e.g. to find the number of articles of known weight from a total weight.
