Title: Improvements in or relating to stuffing boxes
IPC: F16J15/36
Filed: 1930-08-23
Abstract: 359,624. Stuffing-boxes. SULZER FRERES SOC. ANON., Winterthur, Switzerland. Aug. 23, 1930, No. 25235. Convention date, Oct. 7, 1929. [Class 122 (v).] A stuffing box for the shaft of a rotary compresser operates to prevent loss of lubricant when the shaft is stationary, and comprises a spring-pressed sleeve c sliding on the shaft a and connected, in gastight manner, to the casing f by a flexible diaphragm e. The box is flooded with lubricant and subjected to the pressure in the discharge chamber m of the compresser. Thus, whilst the compresser is working, the sleeve c is held away from its seating k on the shaft by the internal pressure, but when the machine stops the spring h overcomes the internal pressure and the sleeve is forced on to its seal. Two such stuffing boxes may be arranged in series on the shaft, the inner one being connected to discharge pressure and the outer one to suction pressure.

Title: Improvements in the manufacture of quinine salts
IPC: C07D453/04
Filed: 1925-10-15
Abstract: 251,526. Akt.-Ges. Chemischer Werte. July 8, 1925, [Convention date]. Quinine salts are separated from the salts of other alkaloids present as by-products, e.g. the salts of cinchonine, cinchonidine, quinidine and hydroquinine, by adding to a solution of the mixed salts sufficient alkali to precipitate the alkaloids present as by-products, heating the mixture at a moderately raised pressure, filtering, and allowing the quinine salt to separate from the filtrate. In an example, the bark of Cinchona succirubra is stirred with water and calcium oxide, extracted with alcohol, and the residue, after distilling off the alcohol, is dissolved in sulphuric acid. The alkaloids present as by-products are precipitated by adding sodium hydroxide and the mixture is heated in a closed vessel at a pressure of from one and a half to three atmospheres to complete the precipitation. After filtering and cooling, pure quinine sulphate separate from the filtrate.
