Title: Improvements in or relating to electrical oscillation generators
IPC: H03C1/30
Filed: 1936-05-05
Abstract: 468,271. Valve circuits. STANDARD TELEPHONES & CABLES, Ltd. May 5, 1936, No. 12688. Convention date, May 29, 1935. [Classes 39 (i) and 40 (v)] In a magnetron oscillator, the modulating potentials are applied simultaneously to the field coil 18 and to'auxiliary electrodes, while the carrier oscillations are applied to the main electrodes. The auxiliary electrodes may comprise end plates 50, 52 or portions 100, 102 of a quadrantally split anode. The highvacuum tube 10, Fig. 3, has a coil 18 for producing a magnetic field which may be axial or inclined, and has end plates 50, 52 so biassed positively as to increase the oscillatory output, or biassed negatively to protect the ends of the glass or quartz envelope from bombardment and sputtering. According to the invention, modulating potentials derived from a microphone 64 are applied both to the coil 18 and to the end plates 50, the adjustments being such as to produce distortionless amplitude modulation free from frequency modulation. Frequency is stabilized by a piezoelectric resonator 90 coupled to the magnetron through a tapped transformer 96 and tuning- condenser 80, and the output is taken from conductors 81, 83. In a modification, Fig. 1 (not shown), the plates 50, 52 are excited in the same phase by a simple transformer instead of the tapped transformer 70, and the tuning system 80, 90 is replaced by a pair of Lecher wires. In a further modification, Fig. 4, a magnetic core 122 having polepieces 129 coaxial with and external to the envelope is provided. The anode is split into four quarter-cylinders ; the tuning circuit 80, 90 is connected by conductors 81, 83 to one pair of opposite quarter-cylinders, while the modulating transformer 116 is connected to the other (separately biassed) pair as well as to the magnetizing coil 124. In a further modification, Fig. 6. (not shown), the modulating voltage is applied to only one quarter-cylinder, the opposite quarter-cylinder being kept at a fixed potential for the purpose of stabilizing the oscillations. The Specification as open to inspection under Sect. 91 describes also a further modification, Figs. 7, 8 (Cancelled, not shown), in which the anode is split into two halfcylinders which are connected to the modulating circuit as well as to the source of carrier ,current. There may be an iron core with a biassing coil as well. as a modulating coil, Fig. 9 (Cancelled, not shown). Various other combinations in which the foregoing features may be used are mentioned. This subjectmatter does not appear in the Specification as accepted.

In a drive mechanism, for a power-driven tool, having a driving shaft, a gear reduction train and a driven shaft including a first gearwheel mounted on an axle 12 in a pivotallymounted carriage 13, the first gear-wheel can be selectively brought into mesh with a second gear-wheel or an idler wheel, the idler being in constant mesh with the second gear-wheel. The drive is transmitted from armature 8 via pinion 9, which is permanently engaged with the first intermediate gear-wheel 10, to the first intermediate pinion 11. Wheel 10 and pinion 11 are mounted as a single component on an axle 12 which is borne by a carriage 13 pivoted on axis Z, Fig. 2. Carriage 13 is moved through a pin-and-link connection 30, 32 by a control member 21 rotated by a handle into either of two positions determined by a spring-loaded ball and detent 24, 28. In the first position the pinion 11 engages the second intermediate gear-wheel 14 which is constantly engaged by an idler wheel 15 mounted on an axle and bearings between a bracket 16 and the gear-case cover 17. Wheel 14 rotates as a single component with a second intermediate pinion 33 and drive in the normal direction via pinion 33 and gear-wheel 35 to the spindle 37. To reverse the rotational direction of spindle 37 the carriage 13 is pivoted to disengage pinion 11 from wheel 14 and into engagement with idler 15. In pivoting to the latter position the control member passes to an over-centre position in which it is held by the forces tending to separate the gears. In modifications the spindle 19 for carriage 13 may be fixed either in carriage 13 or bracket 16 and the axles for the wheels and pinions are mounted in ball-bearings. The drive mechanism may be used in tools with air-operated motors and the tool used to drive portable tools or hoists.
