Filed: 1952-03-13
Abstract: 699,337. Ventilating. AIR-SANA, ERDLUFTVERWERTUNG GES. March 13, 1952 [March 13, 1951], No. 6508/52. Class 137 [Also in Group VI] A plant for the purification of air utilizing the earth as a filter comprises one or more permeable chambers 1 sunk into the ground connected by a pipe system 6-8 to a reversible air supply unit 9-11 so that pure air may be sucked up from the earth or polluted air may be delivered into the ground. The plant shown has three cham. bers 1 each of which is open at the bottom, closed by an air tight cover 1<SP>1</SP> at the top and has perforated side walls consisting of burnt brick. When valves 12, in pipes 6, and valve 13 in pipe 7, regulated by rotary rods 12<SP>1</SP> and pull rod 13<SP>1</SP>, are in the full line positions air is sucked up by pumps 11 as shown by the full line arrows. On reversing the pump 11, which is driven by motor 9 through clutch 10, and turning the valves 12, 13 to the positions shown dotted, polluted air may be delivered into the earth through pipes 8, chambers 2, pipes 6 and chambers 1. The chambers 2 having impermeable walls enclose a filter, adsorption and absorption medium respectively such as filter gauze 3, an active carbon or humus earth 4, and a silica acid gel. 5. The chambers 2 may be made accessible for the recovery of chemical substances. A filter 16 in the inlet pipe 15 prevents blockage of the chambers 2 by smoke. Plates 14 arranged above the chambers 1 prevent the air arriving at the latter by the shortest route and an impermeable slab 17 providing a foundation for unit 9-11 covers the central chamber. In a modification the slab 17 covers all the chambers. The chambers 1 and 2 are sunk to the underground water level so that pure air obtained from the earth is humidified. In a modification the plant is built into artificially established, usually moisture containing, humus earth.

Abstract: 1367341 Inflatable lifejackets BEAUFORT (AIR-SEA) EQUIPMENT Ltd 9 March 1972 [11 March 1971] 6639/71 Heading B7U [Also in Division A3] In a lifesaving appliance the enclosure 12 for an inflatable member 13 includes two longitudinal flaps 15, 16 the free edges of which have secured along them pieces of touch-and-close material 17, 19 respectively. In use the effect of slip-stream force on conventional ejection of the wearer from an aircraft is to urge the joined edges of the flaps together against the wearer's body and retain the enclosure in completed state, whilst the effect of internal pressure on inflation is to cause the touch-and-close materials to peel apart. In the embodiment shown the outer flap 16 has an additional piece of material 18 stitched along its edge in folded-over relationship and this piece 18 also has stitched to it along its edge another additional piece 18a to the one side of which the piece 19 of touch-andclose material is secured.

Title: Improvements in or relating to the manufacture of hydrogen peroxide
Inventor: MARSHALL JOHN GEOFFREY
IPC: C01B15/023
Filed: 1956-03-06
Abstract: In the production of hydrogen peroxide by a process involving alternate reduction and reoxidation of an organic compound in a solvent medium, the hydrogen peroxide produced is extracted from the solvent medium by means of an aqueous solution containing an inorganic hydrogen peroxide stabilizer preferably in an amount of 0.01-0.5 gm/l.  Organic compounds specified are 2-ethyl anthraquinone and phenazine.  Stabilizers specified are alkali metal metaphosphate, pyrophosphate (e.g. normal sodium pyrophosphate and disodium dihydrogen pyrophosphate), and polyphosphate, aluminium phosphate, and sodium stannate.  Ammonium nitrate may be present as corrosion inhibitor.  In an example, a solution containing 90 gm/l. of 2-ethyl anthraquinone in a mixture of xylene and methyl cyclohexanyl acetate was subjected to reduction to produce the quinol in an amount corresponding to 3.0-3.5 gm/l.  After reoxidation and extraction with water, a solution containing 150 gm/l. of hydrogen peroxide was obtained. Specification 465,070 is referred to.

Title: Pulse translator
IPC: H03K3/43
Filed: 1946-03-07
Abstract: 609,519. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. March 7, 1946, No. 7132. Convention date, March 19, 1945. [Class 39 (i)] [Also in Group XL (c)] An electric pulse repeater comprises a beam deflection tube with an apertured barrier electrode, the input pulse deflecting the beam back and forth across the barrier electrode and controlling means which permit the electrons to pass through the aperture when the beam is travelling in one direction and suppress the beam while it is travelling in the other direction, deriving the corresponding output pulse from a collecting electrode. The beam deflection tube comprises a grounded cathode 10, a grid 12, an accelerating anode 13, a_pair of vertically arranged deflection plates 14, 15, the latter plate being grounded, a barrier electrode 17 with an aperture 18 and a collector anode 21 connected to the pulse output circuit. The anode 21 may be of the electron multiplier type or one involving secondary emission. The input circuit is connected to the upper plate 14 through a delay device 5 and a pulse amplitude adjuster 6, and to the grid 12 through a differentiating circuit 4. The latter may comprise a simple resistance capacity network composed of condenser 22 and resistor 23. The electron beam is normally focused either above or below the aperture 18 and when the input pulse applies a potential to plate 14, the beam sweeps past the aperture 18 giving a resultant pulse in the output circuit. As the beam sweeps back on its return, the grid 12. becomes negatively biassed by the action of the differentiator and blocks the beam. The differentiator also gives a positive bias to the grid when the beam is first deflected from its normal position to bring it up to full strength. Narrow pulses of constant frequency and desired amplitude are produced. The device 5 artificially produces a delay in the application of the input pulse to the plates 14, 15, so that the maximum positive and negative biassing potentials obtained from 4 coincide with the sweeping of the beam across the aperture. In a modification (not shown), the input supplies pulses of negative polarity and the differentiator is replaced by a delay device comprising a series resistance, shunt capacity and shunt resistance. The delayed pulse of negative polarity applied to the grid coincides with the return of the deflected beam which is blocked. In a further modification, a separate source of blocking potentials is triggered by the incoming pulse to supply both controlling and blocking potentials to the grid at the proper time. The source may be a multi-vibrator. The beam may be normally suppressed and triggered by positive pulses -from the source. Specification 530,519 is referred to.
