Title: Improvements in tunable coupling networks
IPC: H03D7/18
Filed: 1943-12-30
Abstract: 578,969. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 30, 1943, No. 21873. Convention date, Dec. 30, 1942. [Class 40 (iii)] Image frequency in a superheterodyne receiver is suppressed by a band-pass filter which includes coupled coils L1, L2 so wound and located that the peak of attenuation tracks correctly as the filter is tuned by adjustment of the core K. The coils are bridged by a condenser C3, the effective inductance shunting the condenser C4 is tuned by that condenser to the signal frequency, and the effective inductance shunting the condenser C2 is tuned therewith to a frequency somewhat above the frequency range so as to form a voltage-divider with condenser C1. In the equivalent pi network, Fig. 2 (not shown), the series arm has an anti-resonant peak at the image frequency, and this peak may be sharpened by the insertion of a resistance r to balance out the energy-dissipation in the series arm. In order that the anti-resonant frequency may track with the signal frequency and that the ordinary alignment of the ganged receiver circuits may not be disturbed, the outer primary winding L1, comprising few turns, has a wide pitch so that it covers the whole length of the many-turn inner secondary L2; the pitch may be tapered and the coils are coaxial and spaced apart radially. The coils are wound in the same direction so that the inductance in the series arm of the equivalent pi section may be positive. In a modification, Fig. 3 (not shown), two pairs of coupled coils are employed, the two coils L1 being wound both in the same direction as or both in the opposite direction to the two coils L2. The aerial and the condensers Cl, C2 may be replaced by a loop aerial, Figs. 4, 5 (not shown). The effect of omitting the balancing resistance r is shown by a graph, Fig. 6 (not shown), Specifications 501,644 and 556,774, [Group XXXV], and U.S.A. Specification 2,083,901 are referred to.

Title: Improvements in or relating to processes for the production of phenol
Filed: 1960-06-22
Abstract: Pure phenol is obtained from reaction mixtures produced by the acid cleavage of isopropylbenzene hydroperoxide in which after the elimination of the acid catalyst and the distillation of the acetone, the hydrocarbons contained in the mixture are separated from phenol and the constituents having higher boiling points by azeotropic distillation in the presence of water, the greater part of the phenol itself is separated from the residue containing acetophenone, dimethylphenylcarbinol as well as cumyl phenol and other polymerisation and condensation products in a subsequent column and is transformed into pure phenol in one or more subsequent distillation columns, while the residue produced in the crude phenol column is cracked by heating in the sump of a column or other suitable vessel provided with a return flow of the aqueous phase from the hydrocarbon column, and the vapours from the cracking column are fed without intermediate condensation into a subsequent distillation column also provided with a return flow of the aqueous phase from the hydrocarbon column and the vapours are distilled in such a manner that the acetophenone remains in the sump of this column and the vapours containing low boiling point cracking products are returned into the hydrocarbon column without intermediate condensation.  In an example a residue from the phenol distillation containing 20% phenol is cracked and processed according to the invention and the acetophenone residue obtained from the sump of the column following the cracking column is found to contain only 6.5% phenol.

Abstract: 811,361. Separating solid materials. BLAW-KNOX CO. July 17, 1956 [Aug. 24, 1955], No. 22105/56. Class 117 Gravel is fed in a single layer over the edge of a feeder 11 and drops about 8 feet on to a sloping rigid plate 12, and the harder stones rebound into a compartment 15 and the discard falls into a compartment 16. A wall 14 dividing the compartments is pivoted at its base, and the distance of the top of the wall from the plate 12 is adjustable to control the proportion of soft stone collected in the compartment 15. The discard is then subjected to further similar stages of separation whereby more hard stones are removed. In each stage the distance between the top of the divider wall and the impact line on the rebound plate becomes successively greater and the widths of the feeders becomes successively smaller. As shown, the discard flows from the compartment 16 through a slot 17 on to a feeder 19 from which it falls on to a second rebound plate 20, and the discard of this stage passes into the compartment 24 and the harder stones fall into the compartment 23. A screw conveyer 26 and an elevator 27 feed the discard to a feeder of a third stage arranged adjacent the second stage. The harder stone product from each stage passes to a common compartment and is withdrawn. The rebound plates should be inclined at about 22¢ degrees to the horizontal so that the angle of rebound is about 45 degrees. The gravel is preferably wet so that the softer and more absorbent stones may be more effectively separated. Graphical data is given indicating the effectiveness of the separation with change of drop height, and showing the effect of varying the horizontal distance of the top of the divider wall from the impact line. Specification 808,526 is referred to.
