Abstract: 278,171. Gledhill, A. H. Sept. 27, 1926. Displaying sub-totals.-To permit reading of the total standing on the totalizer while preventing unauthorized access thereto, indicating wheels are provided, each moved by gearing interposed between it and the corresponding totalizer numeral wheel. The totalizer is under one lock and key and the indicator is visible through a shuttered aperture under the control of another lock and key. Fig. 3 shows in plan the totalizer A the wheels of which carry stepped scroll cams b, Fig. 4, engaged by feelers b<1> forming part of yokes b<2>. A series of numeral wheels constituting an indicator B are set by these feelers through sector rack and pinion gearing, the sectors b<5> being rigid with clutch members b<6> embracing the yokes. The yokes, racks and pinions and therefore the indicator wheels are constrained by springs b'‹ which cause the wheels to return to zero when permitted by the scroll cams. The cover of the register may be in two hinged portions, one under control of an auditor and concealing the totalizer, and the other controlled by the shop manager for access to the record rolls. When the latter portion is opened a shutter b<7> normally obscuring the indicator is freed to enable the manager to read the indicator.

Title: Improvements in or relating to diagnostic compositions
IPC: G01N33/64
Filed: 1948-10-29
Abstract: The presence of ketones in body fluids, e.g. urine, is detected or estimated by a colour change in a composition comprising a soluble nitroprusside, e.g. sodium nitroprusside, an aliphatic amino acid, e.g. glycine, alanine, glutamic acid, arginine, aspartic acid or lysine, and an alkaline material, e.g. disodium, dipotassium or trisodium phosphate, or alkaline carbonates or hydroxides.  The use of a separate alkaline material may be obviated by employing an alkaline salt of the amino acid, e.g. sodium or potassium glycinate. Diluents such as starch, lactose and sodium borate may be added to the composition which may be employed in powder or tablet form or in solution.
