Title: Improvements in or relating to dividing machines
IPC: G06F7/46
Filed: 1953-08-10
Abstract: 735,266. Digital electric calculating-apparatus. MAUL, M. Aug. 10, 1953 [Sept. 11, 1952], No. 22066/63. Class 106 (1). A dividing machine in which divisor multiples are formed automatically and compared with the dividend to select the nearest value for subtraction, is characterized in that, under control of the comparing mechanism, divisor multiples are subtracted repeatedly, the divisor coming closest to the newly obtained partial dividend being selected each time, and column shifting being initiated only when the comparing mechanism detects that the partial dividend has become smaller than the divisor. The invention is described as an improved arrangement of the machine described in Specification 497,039, in which the first to the ninth multiples of the divisor are formed before the division proper; comparing devices determine the highest possible multiple which may be subtracted from the dividend, and after subtraction and registering of the quotient digit, a column shift is made and the comparing operation performed again. The present case obtains economy of apparatus and time of operation by providing for only three divisor multiples 1 Î, 2 Î and 5 Î . The dividend and divisor are sensed from a record card and entered into accumulators DD and DR respectively. The accumulator DR is so constructed that it indicates the first, second and fifth multiples of the divisor on the analysing devices for the accumulator setting. Comparison of these values with the partial dividend is carried out by a device V controlled by an impulse emitter 21. If the partial dividend is smaller than the fifth multiple a relay 5Q (not shown) is energized and shifts its contacts 5Q-2 to connect the diyidend accumulator to the next lower multiple, and so on. The quotient digit is entered in the highest order of the dividend accumulator DD. Substraction is performed by addition of the complement under the dividend accujulator DD. Substraction is performed by addition of the complement under control of an emitter 19. Column-shifting of the' contents of the dividend accumulator is initiated when comparison indicates that the partial dividend is smaller than the divisor. When the division is finished a contact u is shifted and the setting of the accumulator DD,  containing the quotient and the remainder, is transferred to a punching device L for punching the results in the card. In a modification only the first two digits are compared for the purpose of selecting the appropriate divisor multiple. A lower multiple is selected if the compared digits are equal. Specification 665,046 also is referred to.

Filed: 1944-11-16
Abstract: 589,873. Burners, controlling. MAY, P. (Robertshaw Thermostat Co.). Nov. 16, 1944, No. 22733. [Classes 75 (i) and 75 (iii)] [Also in Group XXIX] In an electrically controlled burner in which a solenoid valve controlling the fuel supply is controlled by an electric resistance element heated by the main or pilot burner means are provided for closing the valve if the resistance element circuit fails. In the burner shown the manual or thermostatic opening of a ;gas valve 14 completes the secondary circuit of a mains energized transformer 24 to a bridge having in one arm a series resistor 38, a pilot burner igniting coil 40, and a delayed action switch 42, in the second arm an electromagnetically operated valve 16 arranged between the valve 14 and the main burner 10, in the third and fourth arms respectively resistors '58, 66, having normally low resistances and . positive temperature coefficients of resistance, and in the detector arm a cut-out 70, preferably of the thermal type, having a time lag in operation. The secondary circuit also includes a coil 92 which opens the switch 42 and a switch 76 initially short circuiting the valve 16 with time delays of say 18 and 13 seconds respectively. When the valve 14 is opened gas can pass to the pilot burner 18 but is prevented from passing to the main burner 10 by the valve 16. A large current initially passing. through the out-out 70 decreases as the resistors 58, 66 become heated, the resistors 58 by the flame from the pilot burner and the resistor 66 by the current passing through it, and the current is further diminished on the opening of the switches 42, 76 when the valve 16 opens and the burner 10 is ignited. The current through the cut-out 70 is then insufficient to cause its operation unless the resistor 58 is fractured. Should the pilot burner become extinguished the resistor 58 cools and the current through the valve 16 is insufficient to retain it in the open position. A manually operated switch 82 is provided to allow the pilot burner to be ignited by a match if the ignition coil 40 fails. Specification 572,130 is referred to.

Title: Improvements in electric power amplifiers
IPC: H03F3/02
Filed: 1926-09-15
Abstract: 259,197. British Thomson-Houston Co., Ltd., (Assignees of Alexanderson, E. F. W.). Oct. 1, 1925, [Convention date]. Order apparatus.-Comprises means for ensuring that the output E.M.F. of a power amplifier shall be equal, or bear a constant ratio, to the input E.M.F. Thus in the order apparatus shown in Fig. 1, in which the three rotatable receiver coils 13a, 13<b>, 13<c> set themselves at the same angle with respect to the field coil 15 a; that occupied by the transmitter coils 12<a>, 12<b>. 12<c> with respect to the field coil 14, the output of each transmitter coil such as 12<a> is amplified and applied to the corresponding receiver coil such as 13<a>, and should inequality of amplitude or phase arise between the voltages across the two coils, current flows in the normally inactive coil 36 and restores equality. The circuits for one pair of coils 12<a>, 13<a> only are shown, the circuits for the remaining pairs being similar to these. The output from the transmitter coil 12<a> is supplied through a transformer 19 having a divided secondary 20 to the grids of the pushpull pair of amplifiers 17, 18, the output of which is applied through a transformer 31 to the receiver coil 13<a>. So long as the voltages across the coils 12<a>, 13<a> are equal in amplitude and phase, no current flows in the connecting circuit 35, but any inequality gives rise to current in this circuit, including the primary 36 of the transformer 26. Compensating voltages are thus applied, through the secondaries 25, 29, to the grids of the valves 17, 18, whereby the output voltage is corrected. Alternatively, the arrangement may be such as to maintain a constant ratio, other than equality, between the input and output voltages. In a modification, Fig. 2, two or more push-pull pairs of valves may be arranged in cascade, the input-output voltage ratio of each pair being independently regulated. Thus the voltage of the grid 42 is affected by the input voltage applied through the transformer 19 and by the plate voltage applied through the transformer 44. If these should become unequal, current flows in the upper section of the autotransformer 40, and induces a voltage in the lower section in such a sense as to correct the output voltage in the plate circuit.
