In a taximeter having a mixed time and distance drive a proportion of the distance drive is fed into the time drive so that even when the time drive is in control a fare is derived which compensates for running at low speed in crowded traffic. The fare indicator actuating gear 17 is mounted on a shaft 16 bearing clutches 15, 19 driven by gears 14, 18 in engagement with gears 7, 13 so that the gear 17 is rotated by whichever gear 7, 13 is rotating faster. The gear 7 mounted freely on a shaft 12 is driven from the venicle drive and is connected through a bush 6 with the sun-wheel 5 of a differential gear whose other sun-wheel 3 is connected by a bush 2 to a gear 1 driven by a clock. The two planet gears 8, 9 are connected by a bridge 10 to the shaft 12 which thereby drives the gear 13 in accordance with time and an additional proportion dependent on the distance drive. In another embodiment the clutches 15, 19 are eliminated.

Abstract: 465,052. Linkwork. LINDARS, H. Oct. 29, 1935, No. 29859. [Class 80 (iii)] [Also in Group XXVI] In a valve-gear wherein valves are oscillated through rocking members which are connected to a reversing gear of Walschaert or other form, the rocker arms are operated through mechanism adapted to multiply the angular motion given to the member connected to the gear. In the construction shown in Fig. 1, the gear rod 22 oscillates a lever 21 about a pivot 3, and the lever 21 oscillates the rocker arm 8 through the slotted link connection shown. In a modification, Fig. 2, the lever 21 is bifurcated and operates the arm 8 through links 12, 13 and a beam 11. The angular movement of the arm 8 is a faithful multiplication of the movement of the link 21. The angular movement is double, but the rates may, in some cases, be less than unity. A practical construction of this construction is described, wherein the parts 1, 2 are curved.

Title: A process for the catalytic reduction of sugars
IPC: C07C31/26
Filed: 1949-11-22
Abstract: Sugar alcohols are obtained by reacting an aqueous solution of an optically active monosaccharide with hydrogen at substantially normal atmospheric pressure in the presence of a hydrogenation catalyst containing metallic nickel.  The reduction may be effected at room temperature and in neutral, acid, or alkaline solution.  The reaction is accelerated by increasing the temperature or the amount of catalyst and by adding methyl or ethyl alcohol.  In examples: (1) Raney nickel is added to an aqueous solution of glucose and the air driven out by passing hydrogen through the reaction vessel.  When the escaping hydrogen is pure the discharge cock is closed and the vessel agitated, the hydrogen being absorbed to form sorbitol; (2) as in (1) except that 25 per cent ammonia is added to the reaction mixture, a mixture of mannitol and sorbitol being obtained.  The Specification as open to inspection under Sect. 91 includes two additional examples in which (1) an aqueous solution of commercial glucose containing Raney nickel as catalyst and to which a small amount of a base, e.g. calcium hydroxide is added at intervals to maintain a pH of 9 to 9.5, is treated with hydrogen to yield sorbitol; (2) mannitol is obtained by treating an aqueous solution of fructose with hydrogen in the presence of Raney nickel, pulverized magnesium being added to the mixture to neutralize the organic acids produced in the reaction; (3) wood sugar wort evaporated to about 25 per cent and purified is brought to a pH value of 9.5 with soda lye and then filtered.  An alcoholic suspension of nickel-kieselguhr catalyst is then added and the mixture treated with hydrogen to yield a syrup.  This subject-matter does not appear in the Specification as accepted.
