Abstract

727,438. Liquid levels. WULLSCHLEGER, A. Jan. 19, 1953 [Jan. 18, 1952], No. 1478/53. Class 97 (2). A liquid level comprises a transparent plastic container 1 in one wall of which is a hole 4 containing a closure plug 5 and a smaller hole for use in introducing the liquid extending axially through the closure plug and being closed to seal in the liquid by a metal or other filling 7. The smaller hole may alternatively be provided in another wall of the container, e.g. as at 9 in the wall opposite that containing the closure plug 5. Marking rings 3 may be provided in the level and a phosphorescent compound 11 may be used to aid in sighting of the bubble. The plug 5 preferably has a conical part 12 merging at 13 into a cylindrical part 14 as shown in Fig. 2, but may be barrelshaped.
