Filed: 1973-04-30
Abstract: 1426918 Laminates STANDARD OIL CO 30 April 1973 [9 June 1972] 20425/73 Heading B5N [Also in Division H1] An electronically conducting, ionically insulating current collector or inter-cell connector for a capacitive device (see Division H1) comprises a layer of conductive carbon black loaded elastomer sandwiched between two flexible graphite layers. The graphite layers are each preferably 0À3 tp 10 mils. thick and may have anisotropic conductivity. The elastomer layer may be 2 to 10 mils. thick. The elastomer may be a natural or synthetic rubber, examples of the latter being disclosed, and may include promoters, e.g. nitroso-compounds, to increase its conductivity. The elastomer layer may be applied to one of the graphite layers, optionally as a solution, by calendering, silk screening, spray or brush coating. Alternatively a sheet of the elastomer, prepressed or calendered to desired thickness, is placed between the two graphite sheets. The laminate is consolidated by pressure prior to curing the elastomer by nuclear, ultra-violet or infra-red radiation, steam, hot air or vulcanizing. Comparative examples disclose a single graphite sheet laminated to the loaded elastomer, the latter having a smooth or a roughened surface.
Patent GB-362466-A (GB)
Title: Improvements in fluid separators
IPC: B01D17/02
Filed: 1930-07-05
Abstract: In apparatus for separating liquids of different specific gravity or for separating liquid from gas the lighter fluid is drawn through the separator by suction and a valve through which the heavier fluid is discharged is kept closed by the suction and opens when the suction is released.  The apparatus shown is suitable for separating water from petrol as it passes from a supply tank to a petrol pump.  It is also stated to be applicable for the discharge of condensate from natural gas pipe lines.  From the supply tank 124, Fig. 3, petrol passes to a separating chamber 10 containing a float 12, which, as described in Specification 322,654, [Class 46, Filtering &c.], operates an upper needle valve 46 controlling the discharge of petrol through a pipe 84 and a lower needle valve 50 which controls the discharge of the separated water.  The discharge of the water is further controlled by a valve 104, Fig. 4, which is held closed by the suction of the pump.  The spindle 110 of the valve and that of a weight 118 slides through a bearing 114, but the valve has a longer movement than the weight, which therefore aids the opening of the valve when the suction is released but does not hinder it during the earlier part of the closing movement.  The discharge of the water is hastened <PICT:0362466/III/1> <PICT:0362466/III/2> <PICT:0362466/III/3> by the admission of air through apertures 126 to the housing 18 and thence through the pipe 22 to the top of the chamber 10.  The apertures 126 are normally closed by a valve 130 which is lifted to open the apertures by an oscillating member 138 connected by a follower 140 and a plunger 146 to the valve 50, the connections being such as to allow of lost motion.  The up-and-down movements of the valve 130 may be arranged to make electric contacts which cause the operation of a switch to stop and start an electric motor which drives the petrol pump.  The float 12 is weighted by liquid ballast introduced through stand pipes 36.  The float is surrounded by a screen 92 held in position between an upper deflector 82 and a lower deflector 94.  To allow of correct alignment with an aperture 48 the valve 46 is mounted loosely on its spindle which is connected to the float by springs 66.  In the modified apparatus shown in Fig. 13 there is an auxiliary separating chamber 188<1> above the chamber 10.  Light liquid passes down to the chamber 10 through a stand pipe 192.  Heavier liquid will collect in the chamber 188<1> but subsequently pass through apertures 194 in the base and at the bottom of the stand pipe.
