Title: Removal of gases by electrodeionization
IPC: B03C3/00
Filed: 1963-06-11
Abstract: Substances which are at least partially ionizable in water are removed from nonconducting <PICT:1019507/C6-C7/1> non-aqueous fluids which are not water-soluble by passing the fluid from line 17 in the presence of moisture through one or more sorber chambers 12 disposed between cathode and anode chambers 2, 4 and bounded by alternating cation and anion ion-selective membranes C, A, the sorber chamber(s) containing a macroporous filler 16 which is either a strongly basic or strongly acidic ion-exchanger depending on whether the impurities to be removed are weakly acidic or weakly basic, passing D.C. sufficient to dissociate the moisture present into hydrogen and hydroxyl ions and to cause migration of at least part of the impurity substances through one of the selective membranes, and removing the treated fluid from the sorber chamber(s) along line 18. If more than one sorber chamber is used they are separated from one another by washing chambers 14 which together with the electrode chambers are fed from line 20 and if not supplied with a sufficiently conducting liquid, e.g. distilled water, an organic liquid or a gas, are packed with a bridging ion-exchange filler 19 which may be a mixture of cationic and anionic materials.  The filler may be particulate fibrous, woven, expanded or shaped materials.  As described, the process may be applied to the removal of H2S, SO2, NO2 from air; of CO2 from air or exhaled anaesthetic gases; mercaptans, H2S, SO2 from natural gas or gasoline; of CO2 or NH3 from nitrogen; of H2S from a methane-hydrogen mixture; and also to the removal of HCN and CH3COOH. If the fluid to be treated is dry moisture or liquid, water may be introduced into it before it is fed to the sorber chamber or the sorber chamber may be periodically fed with water if insufficient water passes through the membranes by capillary action.  The fluid to be treated may be repeatedly circulated through the treatment cell or through a series connected group of cells.  In the latter case the electrodes of one polarity may be common to adjacent cells.

Title: Improvements relating to rocket motor and like structures
IPC: F02K9/97
Filed: 1954-08-10
Abstract: 749,231. Rocket motors. CARBORUNDUM CO. Aug. 10, 1954. No. 23192/54. Class 9(2) A rocket motor for burning solid or liquid fuels comprises a combustion chamber 7 with a discharge port 8 opening into an exit nozzle 9. The chamber lining 11 and the throat 12 are formed from premoulded and prefixed refractory material, the lining 11 having a rear part 13 tapered towards the throat 12. The lining 11 and throat 12, which may be made from granular silicon carbide bonded together by boron carbide and boron nitride, are seated in an outer metal shell 15 by a layer 16 of castable refractory cement, e.g., hydraulically setting calcium aluminate cement. This cement is also poured around a former core 10 to make the body 17 of the exit nozzle 9. To bolt the shell 15 to a fuel injector head a flange 18 is provided. In an example, a mixture comprising 33 parts of 30 grit size silicon carbide grain, 33 parts of 46 grit size silicon carbide grain, 4 parts of 180 grit size silicon carbide grain and 30 parts of 320 grit size boron carbide, all parts being by weight, are pressed in a steel mould at 50,000 p.s.i. to form the throat 12. Before pressing a temporary binder such as an aqueuous solution of polyvinyl alcohol is added to the mixture. Alternatively, dextrin, waste cellulose-sulphite liquids and powders, resins or waxes may be added. After moulding the member 12 is dried at 225‹-250‹F. and then placed in a high-frequency electric furnace and fired in an atmosphere of nitrogen. The lining 11 may be made in the same way or by tamping or pressing. Other high temperature resistant materials such as granular silicon carbide bonded with boron and zirconium carbides may be used to make the lining 11 and throat 12. To assemble the rocket motor, the liner 1 and throat 12 are united with a refractory cement and placed on the former core 10, on which is also supported the steel shell 15. The intervening space is then filled :with the cement layer 16. This cement may be 45 per cent alumina, 35 per cent lime, 15 per cent iron oxide and 5 per cent silica. Alternative cements include aluminium oxide-sodium silicate compositions and zirconia-sodium silicate compositions. When the cement has hardened, the former core 10 is removed and the structure oven-dried. In a modification, Fig. 3. the throat member 14 is further reduced in size and the exit nozzle is formed from a foamed refractory cement 21 enclosed in a metal casing 22, which is welded to the shell 15. Openings are provided in the casing 22 through which the cement may be poured. Specification 743,317 [Group XII] is referred to.

Title: Improvements in and relating to shutter arrangements for photographic cameras
IPC: G03B9/08
Filed: 1933-08-22
Abstract: 424,886. Photographic shutters. MOORE, H. A., 150, Southampton Row, London. Aug. 22, 1933, Nos. 23337 and 23338. Convention dates, Feb. 19, 1933 and April 10, 1933. A Specification was laid open to inspection under Sect. 91 of the Acts, June 18, 1934. [Class 98 (i)] A shutter comprises a centrally apertured diaphragm, an apertured rotor normally closing the diaphragm aperture, and a release lever carrying an apertured disc and having a driving element adapted to rotate the rotor to bring all three apertures into coincidence for making the exposure, and then to release the rotor to permit it to return to its original position under spring influence. As shown, in the camera lens mount is arranged a diaphragm m having an aperture o on which is mounted a rotor r acted upon by a spring w which rotor has an aperture j. The release lever i is provided with a disc y having an aperture 2. When the release lever v is rotated, the nose z engages the rotor r to bring all three apertures o, j and 2 into coincidence. The rotor r is disengaged from the nose z by running up the oblique top of the pin s and returns to its original position. The release lever v slides under the rotor on release to return to its original position. Rotation of a movable portion of the lens mount limits the motion of the release lever to the position where the apertures coincide, to give time exposures. Further rotation prevents any movement of the release lever. In a modification, a pin with an oblique top is mounted on the rotor. In a further modification an extension on the release lever co-operates with a pin on the rotor. The rotor is pressed down by a spring. Specification 424,688 is referred to. The Specification as open to inspection under Sect. 91 comprises also a shutter having a non-apertured rotor turned by the engagement of the release lever with a bevelled pin on the rotor, and also a shutter having a non-apertured rotor turned by the release lever through an intermediate bell-crank lever. This subject-matter does not appear in the Specification as accepted.
