Title: Process of manufacture of hexachloride and products obtained by this process
IPC: C07C17/02
Filed: 1945-08-21
Abstract: Benzene hexachloride is obtained by the addition of chlorine to benzene in the presence of an oxidizing catalyst and of a very small amount of water.  Suitable oxidizing catalysts mentioned include the oxides and oxyhalides of nitrogen.  The amount of water used is of the order of the amount chlorine gas will carry when used direct from the electrolyzer.  It is stated that in the process of the present invention the water acts as a fundamental catalyst.  An apparatus is described and illustrated for carrying out the process which consists essentially of a vessel for producing benzene vapour, a reaction tower for receiving simultaneously the benzene vapours and a mixture of wet chlorine and the oxidizing catalyst, and a condenser for condensing the products of reaction, and a filter to remove the benzene hexachloride.  It is preferred that the reaction should be carried out in the presence of diffuse light.

Patent GB-1550556-A (GB)
Title: Fluid-flow plug-and-socket couplings
IPC: F16L37/00
Filed: 1977-05-23
Abstract: The plug-in coupling comprises a plug-in socket (1), a plug (2), a blocking ball lock (6, 7) and a shut-off valve which is arranged in the plug-in socket (1). The blocking ball lock (6, 7) releasably fastens the coupled plug (2) in the plug-in socket (1). The plug-in coupling is to be capable of being coupled in use both in high pressure and in low pressure installations in a pressure-relieved manner and therefore can be used for any nominal values and with low levels of pressure loss. This is achieved by designing the shut-off valve as a piston (12) which can be displaced in an axially resilient manner over the inside aperture (13) of the gas pipe (3) and is connected via a passage (22) to the space (19) in which it moves. The passage (22) equalises the pressures in the spaces in front of and behind the piston (12). The shut-off valve is open when the plug (2) is coupled and connects the gas pipe (3), which is introduced perpendicularly to the axis, with little resistance to the pipe which adjoins the plug-in connection (5) and leads to the user. Without the plug (2), the shut-off valve seals off the gas pipe (3). <IMAGE>
