Title: Improvements in or relating to radio receiving circuit-arrangements
IPC: H03B21/02
Filed: 1950-09-21
Abstract: 682,734. Superheterodyne circuits ; frequency-modulation. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 21, 1950 [Sept. 24, 1949], No. 23210/50. Class 40 (v). In a self - oscillating frequency - changing arrangement comprising two mixing valves 2, 4, Fig. 3, to both of which the signal is applied, via terminals 1, 1, the output of the first valve being connected by a network N1 to the input of the second valve and the output of the second by way of a further network N2 to the input of the first, the first coupling network N1 is chosen such that its phase/frequency characteristic is of steeper slope than the corresponding characteristic of the second network N2. The first network is also so chosen that the phase/ frequency characteristic exhibits a maximum value which when divided by the slope of the phase/frequency characteristic of the second network results in a frequency less than that separating adjacent transmitters. It is shown in the Specification that these conditions give a frequency-changing circuit in which the frequency of the signal produced across the first coupling network N1, and which comprises the intermediate frequency, is affected to only a small extent by inaccurate tuning of the second network N2, while at the same time the arrangement is not susceptible to " capture " by a strong transmission adjacent the desired channel. As shown, Fig. 3, the network N1 comprises tuned primary and secondary circuits, 7, 14, respectively, the I.F. output being taken from the latter, and an untuned winding forming the coupling to the valve 4; the required phase/ frequency characteristic, Fig. 4 (not shown), is produced by a shunt circuit comprising resistance 11 in series with a circuit 12 also tuned to the intermediate frequency. The network N2 comprises a parallel-resonant circuit including a variable condenser 9 for selecting the signal frequency to which the frequency-changer will respond. In order to avoid distortion of amplitude-modulated signals the signal fed back to the inner grid of the valve 2 is limited by means of grid current, a leak resistance 17 being provided. An embodiment of the invention, Fig. 5, modified for the reception of frequencymodulated signals, is arranged so that the I.F. output is of constant amplitude. To this end a locked oscillator 20 is inserted in the network N1; the anode circuits 21 are heavily damped so that the feed-back is substantially free from phase-shift. Specification 652,464 is referred to.

Title: Process for producing crystalline trimethylolphenol
Filed: 1958-07-22
Abstract: A process for producing crystalline 2, 4, 6-trimethylolphenol comprises forming a mixture of an alkali or alkaline earth metal salt of 2, 4, 6-trimethylolphenol with an inert organic liquid in which the trimethylolphenol is substantially soluble, in an amount of less than 5 ml. per gram of the salt, contacting the mixture, which is either anhydrous or contains water in an amount up to 1 mol of excess water per mol of trimethylol phenate, with an acidic material which forms a neutral and substantially insoluble salt with the cation of the alkali or alkaline earth metal salt of the 2, 4, 6-trimethylolphenol, removing the insoluble salt formed and recovering crystalline 2, 4, 6-trimethylolphenol from the organic liquid.  The salts preferably used are the sodium, calcium or barium salts which may be dissolved in a lower alkanol, ketone or ester, using preferably 0,75-3 mols per gram of salt and neutralised to pH 5 to 7 at 15-45 DEG C. with an acid such as HCl, H2SO4, CO2, H3CO3, SO3, oxalic acid or the acid form of a solid cation exchange resin. The reaction is carried out so that there is no more than 1 mol of water present in excess of that liberated by the neutralisation or required to form the acid of an acid anhydride and the crystalline product may be recovered by removing the organic liquid at below 50 DEG C. and recrystallising or by precipitating from the organic liquid by addition of a second liquid in which the product is insoluble.
