IPC: C08G77/60
Filed: 1962-09-24
Abstract: The invention comprises organosilicon hydrides of general formula HR2SiR1SiR2H, where R is a monovalent hydrocarbon radical and R1 is a butylene radical.  R may be phenyl, tolyl, naphthyl; phenylethyl, benzyl; methyl, ethyl, propyl, butyl, octyl; vinyl, allyl; cyclohexyl, cycloheptyl; cyclohexenyl and cycloheptenyl. They are obtained by reacting a diorganohalosilane of type HR2SiX with a dihalohydrocarbon of type R1X2, where R and R1 are defined above and X is chlorine or bromine, in the presence of an active metal in the temperature range 0-120 DEG  C.  The active metal is preferably Mg, but may be an alkali metal such as Na. Conventional organometallic reaction procedures are used.  A Grignard-type reaction wherein the diorganohalosilane and the dihalohydrocarbon are reacted in the presence of Mg, or the di-Grignard of the dihalohydrocarbon is preformed, is preferred. The products may be hydrolyzed to form polymers, or the hydrolyzates may be co-polymerized with organohalosilanes or organopolysiloxanes.  Hydrolytically stable oxygen-free copolymers having a repeating unit -A-R11-Si.R2-R11- where A is -R2Si.R1.SiR2-, and R11 is -CR111H-CR2111-or -R1111-CR111H-CR2111-, R111 being H or R, R being defined as above and R1111 being a divalent hydrocarbon radical, are prepared by copolymerizing hydrides of this invention with e.g. a di-alkenyl silane of formula CR2111=CR111-SiR2-CR111 =CR2111, using a chlorplatinic acid catalyst.  An example is given of the preparation of 1 : 4-bis-(dimethylsilyl) butane, and its reaction with diphenyldivinylsilane to give a thermoplastic polymer with adhesive properties.

Abstract: 981,158. Radio-frequency systems; transistor muting circuits. MOTOROLA Inc. Sept. 24, 1963 [Oct. 16, 1962], No. 37555/63. Headings H3T and H4L. A frequency-modulation radio receiver is provided with muting circuits which may be switched so that muting is actuated by the presence of noise in the absence of a predetermined tone signal or alternatively is actuated by noise and a signal from the I.F. stage other than the predetermined signal. As shown the output signal of the I.F. stage 19 of the receiver is supplied via a limiter 21, 23, to a discriminator 61 feeding loud-speaker 72 through amplifiers 69, 70. Detected noise signals across decoupling resistor 37 are supplied via a low pass filter 77, 79, 81, 83 and adjustable muting control 87 to the base of transistor amplifier 89, the output of the amplifier 89 being voltage-doubled at 101, 103 and supplied to the base of the transistor 69 to cut off the audio output signal. In addition, the I.F. signal at point 35 is coupled via capacitors 107, 109 to the base of the squelch amplifier 89 so that it also operates via the voltage doubler 101, 103 to block the audio signal. A portion of the output of the discriminator 61 is supplied via a low pass filter 115, tuned to the frequency of the tone signal, and via amplifiers 119, 121, 123, to a coil 127 operating a vibrating reed 129 which closes contact 131 and provides a voltage via a filter 133, 135, 137 to render a diode switch 139 conductive. This shunts any input to amplifier 89 to earth and allows amplifier 69 to pass the audio signals to the output stage. When switch 143 is closed the muting is operated only by noise in the absence of a carrier and the receiver will monitor all signals to which it is tuned and will also be responsive to the tone signal. When the tone signal is not being received the capacitors 126, 130 by-pass highfrequency noise around filter 115 to the base of transistor 119 the amplitude being sufficient to override the low-frequency noise passed by the filter 115 to prevent false operation of the contact 131. Upon receipt of the tone signal contact 131 will close and cause diode 128 to conduct to short the by-pass circuit.
