Abstract: The present invention relates to a spin coating apparatus for feeding a clean liquid at a fixed rate. In any of the feeding apparatus in the prior art, no constituent other than a filter has the function of eliminating foreign matter, and the operation of feeding a liquid under precise control is not attained. This results in the problem of the mixing of the foreign matter (and air bubbles) in the feed liquid, and the problem of nonuniformity in a feed speed as well as a feed amount. As expedients for solving these problems, the present invention provides the functions of automatically sensing and excluding factors for the appearances of the foreign matters, and devices for automatically and precisely controlling feed control elements such as a pump, thereby feeding the clean liquid in a constant amount and at a constant speed.

Abstract: In the equipment for drawing off milk samples from a milk conveyor pipe (1), in order to remove any milk remaining from the previous supplier and adhering within the suction pipe (5) and the injection syringe (6), before taking a sample from the current supplier the suction pipe (5) and the injection syringe (6) are filled with milk and after being completely filled they are emptied again by pumping the milk back into the conveyor pipe (1). The process of filling to fullness is monitored by a control means (9) which operates a hose pump (7) such that only the exact quantity of milk required to fill the suction pipe (5) and the injection syringe (6) is conveyed. Only after this filling and emptying procedure is the injection syringe (6) inserted into a sampling bottle (8) disposed on a dish (15) which can be raised. A holding down device (16, 17, 18) guarantees perfect withdrawl of the injection syringe (6) from the sampling bottle (8) when the dish (15) is lowered at the end of the sampling.
