Abstract: 1,104,417. Washing containers. ROSS SCIENTIFIC CO. Ltd. 29 May, 1965, No. 22956/65. Heading B8T. A container 11 to be washed internally, e.g. a cell for a spectrophotometer, is inverted and placed on a washer 7 within a cup 6 at the top of a main tube 1 provided with a jet tube 4 connected by a branch pipe 2 to a reservoir 3 containing washing liquid. A stopper 8 connects the main tube to a flask 9, and when a vacuum is applied to the flask via a nozzle 10, washing liquid is sprayed from the jet tube into the container and falls therefrom into the flask. When all the liquid in the reservoir has been sprayed, air is then ejected to dry the container interior. Several jet tubes and one or more branch pipes may be provided, in which case the washer has several holes. Vacuum may be produced by a pump, or by using a tube connected at one end to a water tap and having a branch tube conneoted to the flask nozzle.

The bearing 30 is a generally cylindrical aluminium collar and has an upper flange 31 to which the support member 22 is secured by swaging a shoulder portion 35 of the bearing 30 over the edge of the central opening of the support member 22. The flange and the support member are so formed that the angle α between the undersurface 31' of the flange and a line perpendicular to the axis B of the bearing 30 is 3-7. The bearing 30 also includes a horizontal annular bearing surface 33 for the swivel plate 50 which fits over the shank portion 34 of the bearing. The lower part of the shank 34 has an annular groove 37 to receive a snap clip 70 as a retaining member. The swivel plate 50 which is stamped from steel then cadmium plated, has a flange 52 of a curvature conforming to the curved edge 92 of the sole, and several spaced alternately raised and lowered lands 54, 55 which form the bearing surfaces. The plate 50 also has several apertures in which threaded nuts 57 are fitted to receive threaded screws 21' extending from each stud 21.
