IPC: G01N1/18
Filed: 1958-06-13
Abstract: 840,999. Liquid sampling. MIDDLESEX COUNTY COUNCIL, ADMINISTRATIVE COUNTY OF. June 13, 1958, No. 19023/58. Class 106(5) A machine for taking samples of liquid, particularly sewage, comprises a pump B which delivers the liquid to a tank C and thence through a pipe H to a measuring vessel J which tips to deliver its contents to a trough K and through a pipe L to sample bottles V. At the same time as the pump is energized by a timing switch, a solenoid-operated valve A on an outlet from the tank C is closed and the rising level in the tank C raises a float F and a flexible pipe E connected to it so that the liquid is delivered into the pipe H. When the vessel J tips, at a point adjustable by a screw M, a cord P raises a shutter N so that further flow in the pipe H is prevented, the excess liquid passing into an overflow pipe Q. When the time switch reaches an "off" position, the pump stops and the valve A opens to discharge the tank C, the fall of the float F lowering the shutter N and tilting the vessel back to initial position by means of a bar G. On completion of the pumping cycle, the time switch starts a motor R to rotate the funnel K until the pipe L is over the next sample bottle and the motor is stopped by a mercury switch O operated by pins on a collar S. When all the bottles are filled, the whole electrical circuit is isolated by a mercury switch T operated by a stop U.

Convention dates, Oct. 23, 1933 and Nov. 13, 1933. [Class 55 (ii)] In the removal of sulphur compounds from gases containing them by passing the gases through layers of porous bodies, comprising mainly ferric hydroxide, and subsequently regenerating the porous bodies by aeration, only completely sulphided layers are so treated. The formation of sulphur shells around the porous bodies, due to the rapid alternation of sulphation and aeration, is consequently avoided. In a system comprising four layers a ... d, layer c is regenerated once, and layer b three times, to every nine regenerating periods of the first layer a. The porous bodies may be contained in a number of boxes arranged in series and in the regenerating step, the first container after it has been regenerated alone is shifted to the last place in the series, before the sulphur-containing gases are again admitted to the boxes.
