Abstract: 1,005,302. Transistor oscillator circuits; keying. MOTOROLA Inc. Sept. 11, 1963 [Sept. 14, 1962], No. 35866/63. Headings H3R and H3T. The output of a tone oscillator comprising transistor amplifiers 17, 25 and a feed-back path including tuning fork 11 with drive and sensing coils 13, 15, respectively, is rapidly built up to a usuable amplitude on operating key switch 32 by applying a momentary surge of direct current to the drive coil 13 to shock the fork into oscillation and by maintaining the feed-back at a high level for a predetermined period after operating the switch. The surge is produced by capacitor 47 which charges, when the switch is operated via the drive coil 13 and the feed-back from the collector of transistor 25 to the drive coil is maintained at a high level until the voltage across capacitor 53, which is charged via resistor 55, reaches a value which reduces the impedance presented by diodes 49 and 51 across the feed-back path. The action of the diode circuit then tends to maintain the oscillator output which is obtained from the emitter circuit of transistor 17, at a steady level.

Abstract: Mixed polyalkylene oxide-polyethylene oxide condensates are prepared by condensing an a , b -alkylene oxide or mixture of such alkylene oxides, having an oxygen to carbon ratio up to and including 0,4, with a low molecular weight organic compound containing at least one reactive hydrogen atom and having a detergency factor (as defined in Specification 776,661) less than 100, to produce a hydrophobic condensate having a molecular weight of 500 to over 900 and a detergency factor above 100, and thereafter condensing the hydrophobic condensate with a mixture of ethylene oxide and at least 5 weight per cent of a higher a , b -alkylene oxide, said mixture having an oxygen to carbon ratio greater than 0,4 and constituting 5-90% by weight of the final product.  Suitable low molecular weight organic compounds mentioned are n-propanol, benzene sulphonamide, methanol, ethylene glycol, n-butanol, 1, 3-butylene glycol, acetic acid, oxalic acid, glycolic acid, mono-, di-and tri-ethanolamine, butylamine, diethylamine, aniline, phenol, resorcinol, diethylmalonate, propylene glycol, sorbitol, glycerine, pentaerythritol, butyl mercaptan, ethylene diamine, and acetamide. If desired the first a , b -alkylene oxide or alkylene oxide mixture may be polymarized before condensing it with the low molecular weight starting-material.  Suitable alkylene oxides for this first condensation are propylene oxide, butylene oxide, or a mixture of 60-95% propylene oxide with 5-40% ethylene oxide.  The condensations are preferably carried out at elevated temperatures and pressures in presence of alkaline catalysts, e.g. sodium alkoxide, sodium hydroxide or a quaternary ammonium base. Preferably the second condensation is with a mixture of ethylene oxide and propylene oxide, but the propylene oxide may be replaced with butylene, amylene, cyclohexane or styrene oxide.  Several examples are given of condensates according to the invention with variations in the molecular weight of the hydrophobic intermediate, in the length of the hydrophilic chains and in the balance of the hydrophobic and hydrophilic elements of the condensates.  The carbon soil removal and foaming properties of the condensates are compared.  In a typical example propylene glycol is condensed in two stages with propylene oxide to produce a hydrophobic polymer with a molecular weight of 1660.  This was further condensed with a mixture of 75% ethylene oxide and 25% propylene oxide.  The products of the invention are detergents, dry cleaning agents or plasticizers for synthetic resins. They have low foaming properties and may be used as defoaming agents in certain processes.
