Title: Improvements in ? decolourisation of sewage effluents, trade wastes and the like
IPC: C02F1/28
Filed: 1936-11-05
Abstract: Sewage effluent and water-borne trade wastes are decolorized by subjecting them to the adsorbing action of sulphonated coal.  The term sulphonated coal is applied to the products obtained by treating coal, including anthracite but not lignite, with a sulphonating agent such as sulphuric acid or chlorosulphonic acid until base exchange properties have developed.  The sulphonated coal is preferably employed in the "spent" condition, i.e. after its base exchange properties have been exhausted.  The sewage effluent and water may be treated in the raw state or after preliminary purification processes. In an example a river water contaminated with sewage effluent and trade wastes was subjected to precipitation by lime, sand filtration and adjustment of its pH value to about 8 by means of treatment with carbon dioxide: it was then allowed to percolate over sulphonated coal granules so as to give a contact time of one minute. Specifications 450,179, 450,574, and 455,374 are referred to.
Patent GB-926716-A (GB)
Title: Improvements in the production of metal oxides
Inventor: OLSON CARL MARCUS
IPC: C01G23/07
Filed: 1959-09-04
Abstract: In the production of metal oxides by vapour phase oxidation of the corresponding metal chlorides, bromides or iodides at temperatures of 800 DEG -1450 DEG C., the reactor wall is made of porous carbon or graphite and is maintained at 500 DEG -800 DEG C. whilst chlorine, bromine or iodine gas is passed inwardly through the porous wall to form a continuous protective gas film to prevent oxide scale deposition.  The ratio by weight of halogen so employed to that liberated in the main reaction per unit time is from 0,1 to 1.  The reactor, Fig. 1, may be the same as that described in the parent Specification.  The reaction zone 6 is fed with an oxidizing gas such as <PICT:0926716/III/1> oxygen or oxygen enriched air, which may contain 0,05 to 10% water vapour, through line 4 and the halide is fed through line 11 to a circumferential slot 13 into the oxidizing gas preferably at right angles to the main axis of flow, as described and claimed in Specification 757,703.  The reactant inlet arrangement is surrounded by a furnace 1.  The porous walls 7 of the reaction zone are formed of carbon or graphite and are surrounded by a jacket 15 to which the halogen shielding gas is fed from line 16. The pores of the carbon or graphite wall may be from 0,05 to 200 microns and the wall and surrounding jacket may extend up to or beyond the circumferential slot to prevent scale deposit thereon. The halogen shielding gas may be heated to 300 DEG -600 DEG C. before passage through the wall and it may be mixed with an inert gas such as nitrogen helium, argon or neon or with a non-oxidizing gas such as carbon monoxide or carbon tetrachloride.  The stated effect of the halogen in titanium tetrachloride oxidation is to form a subchloride such as titanium oxychloride with the already formed titanium dioxide near the wall, the subchloride reacting with chlorine to form tetrachloride which is then reoxidized. According to a typical example, titanium tetrachloride and oxygen containing 2,4% water were fed to the reactor inlets enclosed in a furnace maintained at 1020 DEG C., whilst dry chlorine at 20 DEG C. was fed through porous graphite walls of the reactor.  Reactor retention times may be 0,01 to 5 seconds.  Production of titanium, zirconium, aluminium, antimony, iron, tin and zinc oxides is referred to.
Patent GB-1438166-A (GB)
Title: Air-conditioning system
IPC: F24F3/044
Filed: 1973-06-26
Abstract: 1438166 Ventilating buildings MESSIER 26 June 1973 [26 June 1972] 30319/73 Heading F4V An air-conditioning system for a plurality of rooms comprises an air-conditioning unit 1 which passes conditioned air via a duct 47 to room outlets 49, and extracts stale air from the room through apertures 33 in a false ceiling. A mattress 35 of sound and thermally insulating material is disposed in the false ceiling. The amount of conditioned air supplied to the outlets 49 is controlled by temperature sensitive electrical resistors 53 in the rooms; 55, 57 in the air return ducts 41, 43; 59 in a fresh air intake duct 45; and 61 exterior of the building. A thermostat 25, monitored by a sensor 65 in the air supply duct 47 is located in each room to control a shutter 23 of a ventilation opening 21. In operation, for a low external ambient air temperature, when the air temperature in that room is excessively high, the thermostat closes the shutter, thereby raising both the pressure in the room and the mattress 35 to permit hot air in the upper part of zone 63 to be more easily discharged to the airconditioning plant 1 by way of openings 39. Conversely, when the temperature in the room is too low, the thermostat opens the shutter, lowering the pressure and the mattress. This reduces the rate of escape of hot air in zone 63, while the cold air at the bottom of the room is gradually discharged to the outside via opening 21. For a high external ambient air temperature, the opposite occurs; when the temperature in the room is too high, the thermostat opens the shutter and if too low, the thermostat closes the shutter.

Title: Exposure control mechanisms
IPC: G03B9/26
Filed: 1971-06-29
Abstract: 1345235 Photographic camera shutters POLAROID CORP 29 June 1971 [29 June 1970] 30434/71 Heading G2A A photographic camera shutter comprises a shutter blade 32 movable between a rest position in which the blade wholly blocks an exposure aperture 24 and an open position, resilient means 106 for urging the blade into the rest position, and an actuator 34 movable between first and second positions for causing the resilient means to assume a loaded state, wherein the actuator in its second position engages the blade to move it from its rest position to its open position and releases the blade when at its open position to permit its return to the rest position under the bias of the resilient means. A shutter release lever 48 is connected to a loading member 30, which has a portion 40 which functions as a capping blade, and upon rotation of the loading member 30 an engaging tab 44 thereon engages a surface 96 of a latching member 90 pivotally mounted by a pin 92 on actuator 34. At the same time, a pin 56 extending from member 30 engages a cam 122 formed in a fourth arm member 36 pivotally mounted at 120 to the camera housing. Initially, a camming element 100 fixed to latching member 90 rides up a camming flange 124, provided on member 36 which is pivoted in a counter clockwise direction, and flange 124 is brought adjacent a camming flange 142 provided on a camera base plate up which camming element 100 continues to ride. The shutter parts then assume the situation shown in Fig. 6, and the shutter opening spring 80, shutter closing spring 106, and spring 136 are all in their maximum loaded state. The engagement between element 100 and flange 142 is lost and actuator 34 free to rotate in a clockwise direction under action of spring 80, a surface 98 of latch member 90 engages a tab 64 depending from the shutter blade and the shutter is opened. Upon the shutter becoming fully open, Fig. 9, (not shown) latching member 90 strikes a stop 130. Latching member 90 is rotated clockwise thereby to destroy engagement between members 98 and 64 and the blade is free to close under the action of spring 106. A pin 68 provided on the shutter blade contacts a tab 75 provided on actuator assembly 34 to smoothly arrest the upward motion of the blade. Release of lever 48 allows all parts to assume their original state. The bias of return spring 106 may be adjusted by an end 110 thereof engaging a different notch 66. Stop member 130 is rotatable in either direction to enable adjustment of the position in which the shutter blade is released.
