Filed: 1938-03-16
Abstract: 512,801. Bobbins. LANSIL, Ltd., and WILCOX, A. March 16, 1938, No. 8151. [Class 120 (iii)] A bobbin has a tapered barrel portion 1 with a fixed end flange 2, and a removable end flange 3 secured by a threaded sleeve 4 which is screwed partly into the barrel and partly into the flange. A disc 6 slides on the sleeve 4 and prevents disturbance of the yarn when the flange 3 is rotated for removal. A removable sleeve 7, Fig. 5, is fitted on the barrel to receive the yarn, and its ends may fit in recesses in the flanges. After the removal of the flange 3 and disc 6 a ball-headed cap 9 is screwed on to the sleeve 4 and forms a flush surface with the barrel.

Abstract: 600,076. Frequency modulation automatic noise suppression. PHILCO RADIO & TELEVISION CORPORATION. April 6, 1945, No. 8575. Convention date, Sept. 2, 1944. [Class 40 (v)] A noise-suppression device for frequencymodulated radio receivers having an intermediate frequency amplifier and a limiter' comprises an auxiliary oscillator, the output voltage of which is greater than the threshold voltage of the limiter, and means for applying this voltage to the limiter. A superheterodyne frequency modulated radio receiver comprises an aerial 10, R.F. amplifier 11, local oscillator 13, mixer 12, and I.F. amplifiers 14, 15, followed by a limiter 16, discriminator 17 and audiofrequency amplifier 18. An auxiliary oscillator produces an output which is large enough to operate the limiter 16, at a 'frequency which does not interfere with the intermediate frequency. The output of oscillator 22 is applied to the limiter 16, thus causing it to operate while the receiver is turned. The output of oscillator 22 may be controlled by a delayed automatic volume control 20, which is connected to the output of the first I.F. amplifier 14, in order to reduce the amplitude of the auxiliary oscillator voltage when a signal is received and prevent interference between the auxiliary oscillator output and the desired signal.
