Abstract: ABSTRACT:      "IMPROVEMENTS IN OR RELATING TO METHODS AND        APPARATUS FOR SUPPORTING TUBULAR POSTS"    Disclosed is a method of supporting a road traffic, sign post (20) in which a lower sleeve portion (22) of the post (20) is embedded in the ground and secured therein by concrete (23), an  interference fit tubular adaptor (1,11) is driven into the sleeve (22) to provide a predetermined length of adaptor extending from the sleeve and the upper post portion (21) driven into the projecting portion (3,13) of the adaptor (1,11) so that the upper end of the sleeve and lower end of the post are in an abutting relationship The adaptor (1,11) is required to be weaker than the upper portion (21) of the post (20) in order that it will fracture or bend along a line between the abutting ends of the upper portion (21) and sleeve (20) in event of being hit by for example, a car.  The adaptor (1,11) may have an outwardly directed flange (4,14) to determine  the exten  of penetra-tion into the sleeve (22) and post (21), and outwardly di-rected chevrons (15,16) at the ends to provide "lead-in" portions.  The impact strength of the adaptor (1,11) is predetermined by controlling its wall thickness or providing lines of weakness such as a groove or lines of holes (7).

Abstract: Abstract of the Disclosure Disclosed is an optical fiber coupling device which comprises an optical fiber, a coupling member to which the optical fiber is coupled, a coupling means for coupling the optical fiber to the coupling member, and an optical-fiber fixing section for fixing a part of the optical fiber.  The optical fiber is coupled only at its forward end to the coupling member.  A part of the optical fiber is fixed at a position separated from the forward end of the optical fiber by a specified distance.  Thus, the stress applied to the fixed section of the optical fiber is absorbed into a portion of the optical fiber located between the forward end of the optical fiber and the fixed section of the optical fiber fixed by the optical fiber fixing section and which covers the specified distance, thereby to prevent the stress from being applied to the forward end of the optical fiber.

Abstract: ABSTRACT Present invention relates to a fuel cell and a method of operation of a fuel cell.  The fuel cell at least consists of an anode and a cathode, in which fuel cell the anode is connected with the cathode within the fuel cell through one or more electrical conductors, and the arithmetic product of the total electrical resistance between the anode and the cathode electrically conductive connected therewith within the fuel cell in .OMEGA. and the active area of the cathode in m2 lines between 10-4   and 10 .OMEGA. m2.  The fuel cell is operated so that a stoichiometric excess amount of fuel is present at the anode relative to the amount of oxidant in the cathode chamber(s).  The anode is connected with the cathode within the fuel cell through one or more electrical conductors, and the arithmetic product of the resistance and the active area is as defined above.  Subsequently the external current drain is stopped and also the oxidant supply is stopped at least virtually.  One or more electrically conductive connections is maintained between the anode and the cathode within the fuel cell after the external current drain from this fuel cell has been stopped and also the anode chamber(s) is left filled with fuel.  The advantage of the new fuel ceil according to the invention is the much better stability in time in comparison with otherwise identical fuel cells with a large electrical resis-tance between the anode and the cathode within the cell.

Abstract: ABSTRACT            A process for treating dairy by-products The invention relates to a process for the decationization of by-products of milk, particularly whey for cheesemaking, by ion exchange, comprising passing the by-product in liquid form successively through a weak cationic resin and then through a strong cationic resin and then regenerating the resins by passing an acid successively through the strong cationic resin and then through the weak cationic resin.     This process enables the strong cationic resin to be utilized to 90% of its capacity and from 30 to 40% of regeneration reactant to be saved.   The product obtained serves as an intermediate in the production of lacto-proteins and demineralized lactoserum products suitable for human and animal nutrition.

Abstract: Abstract of the Disclosure SULFUR CURABLE SILICONE RUBBER     Silicone rubbers can not normally be vulcanized or cured with sulfur. For this reason it has been traditionally difficult to co cure blends of silicone rubbers and diene rubbers utilizing conventional sulfur curatives.  This problem has severely limited the utilization of silicone rubber/diene rubber blends in many applications.  However, this difficulty can be easily overcome by utilizing in such blends the sulfur curable silicone rubbers of the present invention. These sulfur curable silicone rubbers are prepared by modifying silicone rubbers which contain pendent vinyl groups with N-chlorothio-sulfonamides.
