Title: A process of hardening gelatine
IPC: G03C1/30
Filed: 1931-07-10
Abstract: Dialdehydes are used as hardening agents for gelatine, the hardening process being carried out either by adding a dialdehyde to a solution of the gelatine, or by bathing the shaped and dried gelatine body in a solution of the dialdehyde.  Both monomeric and polymeric dialdehydes may be used, examples being glyoxal, paraglyoxal, and mesoxydialdehyde.  The invention is applicable to the treatment of photographic gelatine emulsions containing silver halide.  Examples are given.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of dialdehydes for hardening albuminous substances in general.

Title: Improvements in or relating to the manufacture of titanium
Inventor: MOONEY RONALD BARRON
IPC: C22B34/12
Filed: 1957-06-26
Abstract: A process for the manufacture of metallic titanium wherein titanium tetrachloride is reacted with sodium in an inert atmosphere in a reactor at a temperature between 200 DEG C. and the melting point of sodium chloride while maintaining in the reactor an agitated non-adherent particulate bed of reaction products and thereafter recovering titanium from said products, comprises providing a system comprising a vessel connected to said reactor and which permits material to be transferred from the vessel to the reactor and reaction products from the reactor to the vessel and for reaction products to be withdawn from the system by way of the reactor, continuously withdrawing a portion of said p  reaction products still in the form of a non-adherent particulate bed from the reactor into said vessel, forming an agitated non-adherent particulate bed of said withdrawn portion of the reaction products in said vessel, adding sodium to said agitated non-adherent withdrawn portion of reaction products in said vessel, feeding the resulting discrete particles from said vessel into said reactor, feeding titanium tetrachloride into said reactor, permitting interaction to take place in said reactor between the titanium tetrachloride and sodium in said discrete particles to yield titanium and sodium chloride, and withdrawing a portion of the reaction products from the system by way of the reactor.  The reactor consists of a gas-tight mild steel pot with a stirrer, the shaft of which passes through a gas-tight seal in the lid of the reactor, the lid carrying pipes for the delivery of argon and TiCl4.  A screw conveyer enclosed in a mild steel pipe discharges from the bottom of the dispersion vessel into the top of the reactor while an enclosed screw elevator transfers reaction products from the reactor to the dispersion vessel which consists of a gas tight mild steel pot fitted with a mild steel stirrer and means for introducing argon and sodium through its lid.  The screw elevator carries a pipe fitted with a valve which can be opened to ensure a bleed-off for the reactor products. The system is maintained under slight pressure of argon and the additions of sodium and TiCl4 and the removal of the reaction-products are carried out continuously. The rate of addition of sodium is controlled so that the dispersion vessel contains 1% of sodium which has been purified and is molten at 130 DEG C. while addition of TiCl4 to the reactor is at such a rate that the resulting products contain 1% excess TiCl4, the temperature of the reactor being maintained at 600 DEG C.  The amount of reaction products fed to the dispersion vessel is equivalent to the feed from the dispersion vessel to the reactor, the excess of reaction products being tapped off into a receiver where it is heated for one hour at 850 DEG C. to render the titanium less active.  It is then cooled, ground and leached with 1% hydrochloric acid and the isolated titanium washed and dried. Specification 717,930 is referred to.

Title: Improvements in torpedoes
IPC: F42B19/20
Filed: 1930-07-03
Abstract: 360,450. Torpedoes. FLAMM, 0., 47, Sudetenstrasse, Nikolassee, Berlin. July 3, 1930, No. 20177. [Class 9 (ii).] The main motor of a torpedo is driven by a water-soluble driving fluid which is stored in the torpedo in a liquefied or compressed state and which is superheated by the combustion of materials which are normally gases and which interact to produce heat with the formation of substantially water-soluble end products, so that no wake is left by the torpedo. The products of combustion may be utilized to drive the main or auxiliary motors and may be identical with the main driving fluid. In the construction shown, liquefied hydrogen chloride 2, stored in a container 1, is used as the main driving fluid. On firing, gaseous hydrogen chloride passes through a conduit 15 to drive the main motor 14, and is exhausted through a pipe 13. At a later stage, liquid hydrogen chloride is drawn from the container by a pump 23 and passes through a coil 24 in a vaporizer 19, thence through orifices 25 in to the vaporizer, and finally through a reducing valve 26 and reservoir 27 to the main motor. The vaporizer is heated by the combustion of hydrogen and chlorine stored respectively in containers 6, 3. These gases are conveyed by pipes 16, 17 to a mixing vessel 18 wherein they are ignited by an electrically heated filament 32. The products of combustion, i.e. hydrogen chloride, pass thence into the vaporizer and thence to the main motor 14. At the same time, liquid chlorine is drawn from the container 3 by a pump 20 and is forced through a coil 21 in the vaporizer where it is vaporized. The vaporized chlorine is delivered by a pipe 22 to the mixing vessel 18. The pumps 23, 20 are driven respectively by pump motors 8, 8<1>. These motors, and also the steering and other motors 9, 10, 11, are supplied with hydrogen through a conduit 7, the exhaust gases passing thence through a pipe 12 to the exhaust. Reducing valves 31 are provided in the various conduits as shown. A pressure-regulating valve 28 in the vaporizer operates either to regulate the speed of the motor 8 or to regulate a valve in the hydrogen chloride conduit 29. A thermo-regulator 30 also is provided and either regulates the speed of the motor 81 or checks the flow of hydrogen and/or chlorine by actuating valves provided in their conduits. The hydrogen is stored in the container 6 under a pressure of 200 atmospheres. Alternatively, the combustible materials may be (1) liquids, for example liquid hydrocarbons alone or in admixtures, (2) combustible gases such as gaseous hydrocarbons alone or in admixtures, or (3) gases which support combustion such as air, oxygen, nitrous oxide, and the like. As stated above, the products of combustion of these materials are preferably identical with the main driving fluid, thus carbon disulphide and air are chosen when the main driving fluid is sulphur dioxide. The superheating of the main driving fluid may take place outside the vaporizer and may be aided by steam or similar substances to increase the output.

A rotary driving pad for use with rotative abrasive elements has a resilient face member 16 having a large number of individual blocking resilient protuberances 11 adapted to grip and propel a flexible, conformable, fluid-permeable abrasive element while forcing the abrasive element against substantially all portions of an irregularly planar work surface, the outermost extremities of the protuberances lying in substantially the same plane, the protuberances being defined by interconnected channels 12, at least a substantial number of the channels terminating at the outer edges of the face member, the channels permitting detritus to be accumulated therein and expelled centrifugally therethrough. The face member may be of natural or synthetic rubber or may be cut from conveyer belting having a three-ply cloth reinforced rubber back and an integrallymoulded rubber working face. The face member 16 is adhered to a resilient backing member 14 of material substantially softer than that of the face member. The backing member 14 may be of sponge rubber or foamed polyurethane; it may be omitted. The pad is attached by screws 13 to a support member 17, having a clamp 18 for attachment to a cement floor-cleaning machine. The support member 17 may be of laminated wood to which the pad is secured by rubber. Alternatively, the pad may be cemented to an aluminium hub. For treating floors, the pad drives a steel wool pad, an abrasive included three-dimensional skeletal fibrous nylon disc or an open mesh woven coated abrasive fabric disc; detergent solution is used. For treating a steel panel coated with oven-dried pigmented lacquer-type surfacer material the pad drives an open mesh cloth abrasive disc.
