1476096 Coating apparatus ASSOCIATION DU CENTRE DE TRANSFUSION SANGUINE ET DE DESSICCATION DU PLASMA 20 Feb 1975 [6 March 1974] 7100/75 Heading B2L [Also in Division G2] A pilet of smeared blood etc slides to be treated with reagents is held under spring pressure in a reciprocating holder 28, the holder rising each time an intermittently moving endless belt 1 stops so as to apply a slide to a suction cup at location 7. The slide is transported stepwise and when stationary below nozzle 10 receives a predetermined quantity of May Grunwold reagent. A nozzle 12 applies an equal amount of water and a hump 14 causes the slide to tilt to thereby spread the coating. A plate 45 may be oscillated to roll the coating along the length of the slide. Giemsa reagent may be applied via nozzle 16 and washing water by nozzles 19. After passage through a drying oven a probe at 25 distorts the cup and the slide drops to a container 33 via a conveyor 31. An arrangement is described whereby the nozzles are deflected if a cup is presented without a slide.
