Telephonic relays; microphones.-The spring arm carrying the armature of a magneto-microphone relay is pivoted at one end and rests at the other end on an adjustable knife-edge, an intermediate point near the armature being connected by a link and spider frame to the microphone diaphragm. Figs. 2 and 3 are vertical sections through the relay taken in planes at right-angles. The oblique pole-pieces 3 are secured to horse-shoe permanent magnets 2 attached to the underside of a base-plate 1. The armature 6 lies between the free ends of the pole-pieces and is mounted on an arm which is pivoted between screw pivots at one end 7 and has its resilient outer end 9 resting on a knife-edge 10 mounted on a block 12 adjustable vertically by a screw 13. The arm 9 is connected by a link 14 and spider frame 22 to the diaphragm 21 of the microphone. The diaphragm may be secured at its edge to the case 16 but is preferably free at its rim and supported only by the spider frame 22.

Filed: 1925-06-09
Abstract: 249,706. Hutt, A. E. June 9, 1925. Cams and tappets. --- A valve tappet is con. structed of telescoping members 2, 4 between which is arranged a spring 7 adapted to provide clearance between the cam and tappet after the valve is closed. The cam is formed with a small concentric surface at the junction of the closing portion with the base circle, so that when the valve has closed, the linkage 37 between the tappet and the valve is held stationary for a moment, in order that the inertia of the linkage shall not be brought to bear upon the spring 7. The spring then moves apart flanges 3, 5 on the members 2, 4 to provide the necessary clearance. The film of oil which collects between the flanges 3, 5 serves to silence the impact of the flanges as the clearance is taken up prior to the opening of the valve. In modifications, the underside of the flange 5 is spherically curved or fitted with a roller; or the flange may be carried by a rocker 24, Fig. 7, formed with a cam-engaging surface 27; or the flanges may be at the upper end of the tappet as shown at 29, 30, Fig. 8.

The system comprises a writing unit 10, Fig. 2, including a chamber 12, an inlet channel 15 for supplying the chamber with ink, an outlet channel 17, and an electromechanical transducer 20 for generating pressure rises in a chamber 11, which pressure rises are communicated to chamber 12 through a passage 13 and cause the discharge of ink drops through channel 17; and an electrical circuit, Fig. 4, for generating signals for application to said transducer, the circuit including a sinusoidal waveform generator 42 producing a sinusoidal signal of constant amplitude and frequency higher than the highest instantaneous frequency of a video signal produced by a source 41, and a modulator 46 for modulating the amplitude of the sinusoidal signal in accordance with the video signal. The output from generator 42 is passed to a zero crossover detector 43, the pulses from which are fed to sample-and-hold circuit 44 which is operable in the sampler mode when it receives a sampling pulse and changes to the hold mode after an input signal from the video signal source 41 has been sampled. The output of the circuit 44 is fed to modulator 46 where it amplitude modulates the sinusoidal signal from generator 42. The video signal may be digital or a mixture of analogue and digital. Instead of a modulator 46, a bidirectional transmission gate may be used, which is gatecontrolled by the output from the sample-and-hold circuit 44 to produce an amplitude modulated sinusoidal output.

Such manual switches, directly or via a coding matrix, control one or more oscillators to produce the frequency signal which is converted to sound, light, &c. for the remote control. Power is supplied to the oscillator(s) only when one (or more) of the manual switches is actuated. The equipment controlled may be a TV or radio set, a model plane or ship, a toy or garage doors. The transmitter may incorporate a radio receiver, a clock (e.g. for timed control), and a flashlight. Control of channel selection, volume, colour saturation, contrast, hue and brightness of a TV set is possible.
