Abstract: 1473692 Ignition system DUCELLIER & CIE 9 July 1974 [11 July 1973] 30286/74 Heading F1B In an ignition system comprising an ignition signal trigger device 7, e.g. mechanical, magnetic, optical, or ignition advance computer, controlling a power amplifier 17,5 and 6 so that under normal supply voltage a signal from trigger 7 charges a capacitor 21 to render input stage transistor 17 conductive and output stage transistors 5, 6 non-  conductive to induce a voltage in the ignition coil 1, a Zener diode 24 is connected to the base of transistor 17 to render it conductive when a supply voltage larger than a predetermined value is used at starting. With transistor 17 conducting, transistors 5 and 6 remain non-conducting. A signal from trigger 7 changes a capacitor 27 to render transistor 26 conductive, but transistor 17 remains conductive due to the charging of capacitor 21. When the charging at capacitor 21 is completed transistor 17 becomes non-conductive until capacitor 27 is completely charged. In this time transistors 5 and 6 conduct to produce an adequate current in primary winding 2 for the production of a spark.

Convention date, Oct. 13, 1928. [Class 40 (v).] To eliminate hum from supply mains used as a source of power for thermionic valves, push-pull connected amplifiers derive their supply through a tapped resistance, the filaments being supplied in parallel, and the grid tappings are adjusted so as to eliminate mains noise. The voltages induced in the secondaries f, f<1> of the input transformer are in opposite phase, so that the voltages induced in the primary windings g, g<1> of the output transformer are in phase. The grid tapping for valve a on the resistance cde is adjustable, while that for valve b is fixed. Pulsation of supply voltage causes in-phase pulsation in grid and anode potential but these pulsations are in opposition in the two portions g, g<1> of the output transformer and annul each other when of equal magnitude, which condition is obtained by varying the grid tapping.

Abstract: 267,214. Crabtree, A. E. Dec. 9, 1925. Indicating-mechanism; computing-apparatus.- In a weighing-machine of the kind wherein the tare of a containing vessel is determined on a fixed scale and the net weight of the contents of the vessel is determined on an auxiliary adjustable scale coacting with the movable indicating pointer the auxiliary scale is adjustably mounted in front of the fixed scale and movable pointer. As shown in Fig. 1, a movable disc 3 provided with apertures 4 - - 9 may be rotated in front of the usual fixed dial 1 and pointer 2. After placing an empty vessel on the machine the operator moves the disc 3 until an index 10 on the disc coincides with the pointer 2 after which the addition of material to the vessel brings the pointer to view in one of the apertures 6 - - 9 to indicate 1, 2, 4 or 7 1bs, net as desired. In a modification, applied to a fan-shaped dial, instead of a disc 3 an arc-shaped apertured plate slides in front of the fixed dial and pointer. In a spring balance, Fig. 3, an open frame 20 provided with indices 20<1> may be rotated in front of the fixed dial 17 so as to eliminate the tare and give net weight readings. The open nature of the frame 20 allows the spring balance to be used in the ordinary manner. In a modification, Fig. 5, a frame 25 with an arcuate slot carrying indices 25<1> for tare, 1 lb. net and 2 lbs net respectively may be adjusted in front of a fan-shaped chart and pointer by means of a lever 26. A hand-wheel 27 may be provided for fine adjustment. In a modification, Fig. 6, a fully calibrated scale 38 is provided, and the pointer 2 has a hooked portion 40 for indicating on the movable scale. The movable scale of any of the above-described arrangements may be calibrated in units of volume and may have a number of sets of units for fluids of different densities.
