Abstract: 133,157. Haug, N. O. Oct. 3, 1918. Sorting by weighing.-In a machine for digging and sorting potatoes and separating from them materials of different specific weights, special means are provided for sorting the potatoes, stones, clods, &c. into groups according to their sizes and for sorting the articles in each group according to their weights. The potatoes &c. from the sections of a rotary sorting- drum 27 fall singly into the cups 32 of an endless conveyer. The cups 32 are pivoted and counterweighted, and rest on a supporting-track as they pass from the drum 27 to the discharge shoot 37.

Title: Phosphate ester derivatives containing a pyrazolidinyl ring
IPC: C07F9/6503
Filed: 1972-03-24
Abstract: 1374641 Substituted phenyl phosphoric acids and salts thereof RICHARDSON-MERRELL SpA 24 March 1972 [21 April 1971] 13959/72 Headings C2P and C2C The invention comprises a phosphoruscontaining pyrazolidine dione derivative having the formula and its pharmaceutically acceptable organic and inorganic salts. The free acid is obtained by reacting the corresponding 2-(p-hydroxy phenyl)-1-phenyl pyrazolidin 3,5-dione derivative with POCl 3  in an aprotic solvent at 0-50 C. in the presence of a base which forms a salt with HCl, cooling the mixture, adding water, drying the mixture, neutralizing the residue with aqueous MgO and then desalting the solution with an ion exchange resin or purifying by chromatography, e.g. over a resin. The calcium salt may be obtained by cooling the reaction mixture from the POCl 3  reaction step, filtering and then dissolving the precipitate in water having a highly alkaline pH obtained by adding CaO or Ca(OH) 2  to the water. The resulting solution is then concentrated and a water-miscible solvent such as methanol, ethanol or acetone added to precipitate the calcium salt which may contain up to 14 mols of water of crystallization. The calcium salt may be converted to the free acid by use of an ion exchange resin and the sodium salt may be obtained from the free acid by adding a solution of NaOH, Na 2 CO 3  or NaHCO 3 , concentrating the solution and then lyophilizing. Salts with organic bases can also be obtained by adding the base dissolved in a watermiscible solvent to an aqueous solution of the free acid. Examples are given for the production of (1) the calcium salt of the formula in its anhydrous form and in its 8H 2 O and 14H 2 O hydrate forms and also for the enzymatic hydrolysis of the 8H 2 O hydrate form by means of a phosphatase to form the free acid, viz. 4-n-butyl-2-(p-hydroxyphenyl)-1-phenyl- 3,5-pyrazolidindione, (2) the free acid of Formula I, (3) the bisodium salt in the form of its tetrahydrate, and (4) the α-p-phenetidino- N-n-propyl propionamide salt of the free acid of Formula I. The products have therapeutic properties and may be used in admixture with a pharmaceutically acceptable carrier.
