Abstract: 984,844. Gas filters and adsorbers. VOKES Ltd. Jan. 30, 1964 [Jan. 30, 1963], No. 3830/63. Headings B1L and BIT. In a filter for gases, a granular filter medium is contained in cells between two foraminous plates 3, 4, which cells are formed solely by strips 1 bonded to the plates. Preferably the strips 1 slope as shown, so that by-passing of the gas is prevented when the granular medium packs down. Similar dividing strips at right angles to the strips 1 may also slope with respect to the plates 3, 4. The strips may be of metal, plastic, or cardboard and the foraminous walls of perforated or expanded metal or plastic, paper, felt, or woven cloth. The filter element may be formed as a panel or in cylindrical shape. The granular medium may be activated charcoal for the removal of noxious vapours and odours from gases.

Title: Improvements in or relating to phase detectors suitable for use in automatic tuning control arrangements and for like purposes
IPC: H03L7/06
Filed: 1946-02-08
Abstract: 619,864. Phase-difference measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 8, 1946, No. 4055. Convention date, Feb. 9, 1945. [Class 37] [Also in Group XXXVII] A phase detector comprises a pair of gridcontrolled valves 71, 73 fed in phase opposition from one tuned circuit and in the same phase from another tuned circuit, the outputs of the timed circuits being in phase quadrature, so that an output is obtained related to any variation of the phase quadrature. The invention is described as applied to a system for tuning a circuit 30 to the frequency of an oscillator 10. Oscillations from 10 are applied in anti-phase to the grids 71, 73 of a valve 60 as well as to the circuit 30 ; the output of circuit 30 is phase displaced 90 degrees by condenser 31 and applied to the cathodes of valve 60 ; it is shown that an A.C. input to valve 60 appears as an A.C. output whose phase depends on which of the oscillations from 10 or from 30 leads the other. At phase coincidence of the oscillations from 10 and 30, thyratrons 74 are non-conducting and no current flows through the stator of motor 80; but if a phase difference exists, one or other of thyratrons 74 fires to energize the stator to cause rotation of the motor in one direction or the other to tune circuit 30 to resonance with the frequency of oscillator 10, and to adjust condenser 31 to produce the desired 90 degrees phase-shift. The grids 71, 73 may be additionally energized with low-frequency A.C. applied across resistance 66.
