Filed: 1918-04-22
Abstract: 125,896. Bowden Wire, Ltd., and Sentinella, A. E. April 22, 1918. Bell - operating mechanism, spring-driven.-A bell-actuating mechanism comprises a spring-pressed strikef adapted to be engaged by a slide in so as to compress the spring g and be automatically released to strike the bell a when the slide has been moved to an extent determined by the size of the projections r, j and the relative inclination of the striker and slide. The striker is mounted in a cradle e pivoted at c and normally held against a stop l by a spring. On the return movement of the slide under the action of the spring t, the part r strikes the under curved surface of the part j, causing the striker to oscillate on its pivot. The slide may be operated in any manner through a control wire q, and the striker is kept from contact with the bell by a weaker spring h. Specification 125,742, [Class 118 (ii), Signals], is referred to.

Abstract: 579,336. Electrical measuring apparatus. COSSOR, Ltd., A. C., BEDFORD. L. H., BELL, J., and LANGHAM, E. M. Nov. 30, 1942, No. 20008/43. Divided out of 579,325, [Group XIX]. [Class 37] [Also in Group XIX]. Electrical measuring apparatus comprises a circuit for measuring a weighted average valve of the rate of change of a varying direct input voltage over a period of time, said circuit comprising a pair of condensers each arranged to be charged from said input voltage through resistance, said condensers and resistances being so related that the charging time constants of said condensers are different, and means to measure the difference between the voltages across said condensers. The invention is applied to the measurement of the rate of change of an alternating voltage applied at 15 to a diode valve so as to produce a direct voltage of proportional amplitude across the resistance 2 and condenser 3. Resistances 9 and 7 are equal but condensers 6 and 8 are different, whereby a direct output voltage is developed after a time interval between terminals 4 and 5. to be measured by a currentless voltmeter or by the apparatus described in Specification 579,337. In Fig. 2, the condensers 11, 14 are equal and have a common resistance 10, but the time constants are made different by the resistance 12. The rate of change is represented by the voltage between terminal 13 and earth. In both figures, the line shown as earthed may be maintained at any constant amplitude alternating potential to earth in phase with that of terminal 15. If the amplitude of the alternating voltage input at 15 is liable to pass through zero, an alternating voltage of the same phase of wide amplitude may be superposed.
