Filed: 1945-12-17
Abstract: 635,968. Adjusting radio apparatus. MURPHY RADIO, Ltd., and CONNELLY, F. C. Dec. 17, 1945, No. 34129. [Class 40 (v)] In a radio receiver having independent impedances for coarse and fine tuning, the scale and pointer are both movable, one with the coarse adjusting means and making equal movements for equal percentage changes of wavelength, and the other with the fine adjusting means and making the same movement as the first for a given percentage change of wavelength, so that a given station may always be tuned at the same scale reading. As shown, the scale is inscribed on a disc or drum 2 turning with the tuning condenser 1 by means of a cord 3 driven by a coarse tuning sleeve 4 concentric with the fine tuning spindle 10. Fine tuning is effected by adjustment of an inductance 7 by means of a metal core 5, suitably shaped to give the required variation and attached to a pivoted segment 23 moved by a cord 21 carrying a pointer 8 located behind a window in the cabinet. A lamp and optical system, Fig. 2 (not shown), projects an enlarged portion of the scale upon a screen filling the window. In a modification, Fig. 3 (not shown), the frictional resistance of the coarse tuning means exceeds that of the fine tuning and a single knob first adjusts the fine tuning over a limited range and then adjusts the coarse tuning. As an alternative to optical magnification a scale may be inscribed on a flexible band wound from one to the other of two drums by operation of the coarse tuning, Fig. 4 (not shown), or a scale may be inscribed upon a drum in helical lines of steep pitch, the pointer being stretched between two arms rotatable about the axis of the drum, Fig. 5 (not shown). In Fig. 6 (not shown), the scale is connected to the fine tuning means, and in Fig. 7 (not shown), the medium and long wave portion of the scale is fixed and co-operates with a moving pointer, while the short wave portion rotates about the fixed portion and is connected to the fine tuning means.

Title: Improvements in or relating to the recording or reproduction of sound
IPC: G11B17/02
Filed: 1934-11-28
Abstract: 443,801. Sound recording or reproducing machines. BARRETT, A. E., 49, Queenswood Court, Clapham Park, London. Nov. 28, 1934, No. 34239. [Class 40 (ii)] [See also Group XXXIX] In recording on, or reproducing from, disc records electrically, means are provided for making the effective response of the cutter or pick-up at the higher frequencies relatively to that at the lower frequencies greater when the cutter or stylus is near to the centre of the record than when it is more remote. As shown the advance of the pick-up arm brings a piece of soft iron 5 closer to a coil 6 shunting the reproducing circuit and so increases its inductance and reduces its shunting effect on the higher frequencies. In a modification, the arm controls a variable condenser to produce a similar effect. In a recording system, a wiper carried by the recording head engages a series of contacts to cause the successive operation of relays controlling tone-modifying circuits.
