Title: Improvements in or connected with pendulous automatic weighing scales
IPC: G01G1/00
Filed: 1923-03-19
Abstract: 217,337. Automatic Scale Co., Ltd., and Blick, E. L. March 19, 1923. Pendulum-weight apparatus. - An automatic pendulous weighing scale is provided with a lever carrying the scale plate at one end, and having an interchangeable counterweight freely suspended from the other end in the same vertical plane as the connection from the lever to the pendulum. The scale may be adjusted to weigh predetermined loads by changing the counterweight, which operation may be effected without dismantling the scale mechanism. A lever 5 fulcrumed on knife-edges 6 carries a scale-plate 3 at one end, and projects at its other end through a rectangular aperture in the upper part of a counterweight 13. The counterweight is suspended from a knife-edge 12 on the lever, arranged in the same vertical plane as a ribbon 23 which connects the lever to a pendulum 16 provided with indicator 25. Vibration, preventing and neutralizing. - The movements of the lever 5 are damped by a dashpot 28, the piston rod 29 of which is connected to a sleeve 30 mounted on a traversing screw 31 arranged transversely of the lever. Casings.-The housing of the scale is so constructed that all enclosures in the casting are formed in one side only of the housing thus lessening the coring required in casting.

Abstract: 542,316. Vitamins. LEDERLE LABORATORIES, Inc. May 1, 1940, No. 7848. Convention date, May 11, 1939. [Class 2 (iii)] [Also in Group VI] A vitamin-containing liver extract is prepared by extracting finely-ground mammalian liver with acidified water at pH 5.4 at 80‹ C., concentrating the extract to a thick syrup and either adding 95 per cent. alcohol and extracting the precipitate with hot 80 per cent. alcohol or extracting the thick syrup with hot 80 per cent. alcohol; the extract is concentrated to a thin syrup, distilled water and hydrochloric acid being added to make an N/10 solution; the active substances are adsorbed on Fuller's earth and eluted with a mixture of dioxane, methyl alcohol, acetone and distilled water, and the final solution is concentrated until each c.c. corresponds with 100-200 grams of liver. To make a solution suitable for parenteral injection, and containing all the ingredients of the vitamin B complex, the liver extract concentrate made as described above is dissolved together with thiamin and nicotinic acid in sterile water. If desired 0.5 per cent. of alcohol may be added. The Specification as open to inspection under Sect. 91 states that the solution for injection may be made by dissolving the requisite quantities of thiamin, nicotinic acid, flavin concentrate, and vitamin B6 and filtrate factor concentrate, adding phenol and sterilizing. It is stated that additional quantities of vitamin B6 and filtrate factor are obtainable from the supernatant 95 per cent. alcoholic solution remaining after the separation of the precipitate as described above, by evaporating under vacuum, adding distilled water, filtering if necessary, adding active carbon and eluting the adsorbate with saturated aqueous amyl alcohol and then with 50 per cent. ethyl alcohol, the solutions being concentrated until each c.c. corresponds with 150-200 grams of liver. This subject-matter does not appear in the Specification as accepted.

Title: Manufacture of monoaryl tertiary amines or salts thereof
IPC: C07D233/04
Filed: 1945-03-28
Abstract: Tertiary arylamines are obtained by treating a mono-salt of a compound of the formula A-NH-R-Y wherein R represents an alkylene chain, A represents an aryl radical and Y a more strongly basic group than A-NH, with a reactive ester of an alcohol.  Mono-salts are derived from the following acids: hydrohalic acids, sulphuric acid, nitric and alkyl-, aralkyl-, or aryl-sulphonic acids.  The alkylene chain may be branched or unbranched or also form part of a ring, specified residues being ethylene, propylene, decamethylene, 2 : 2-dimethyl-propylene and cyclohexylene.  Y may represent a primary, secondary, or tertiary amino group, e.g. mono- or dialkyl amino, piperidino, napholino, guanidino, amidino, imidazolino, or tetrahydropyrimidino. Specified esters are derived from hydrohalic, alkyl-sulphonic and arylsulphonic acid; and aliphatic, araliphatic, alicyclic and heterocyclic alcohols.  The reaction may be effected in the presence of a diluent, e.g. alcohol or dioxane, and of a catalyst such as sodium iodide, copper powder or copper chloride.  In examples: (1) N-allyl-N-(b -dimethylamino-ethyl)-aniline is obtained by boiling N - (b  - dimethylamino - ethyl) - aniline monohydrochloride with allyl bromide in absolute alcohol; (2) N-benzyl-N-(g -diethylamion-propyl)- is obtained by boiling N-(g -diethylamino - propyl) - aniline monohydrochloride (obtained from aniline and g -diethylamino - propyl chloride hydrochloride) with benzyl chloride in absolute alcohol (benzyl bromide or p-toluene sulphonic acid ester may be used instead of the chloride); (3) N-benzyl-N - (g  - dimethylamino - propyl) - 2 - anisidine, is obtained by treating N(g -dimethylaminopropyl)-2-anisidine with benzyl chloride in alcohol solution; (4) N-benzyl-N-(b -methylamino-ethyl)-aniline, is obtained by reacting N - (b  - methyl - amino - ethyl) - aniline monohydrochloride with benzyl chloride as above; (5) N - (b  - amino - ethyl) - aniline is obtained by reacting N-(b -amino-ethyl)-aniline monohydrochloride with benzyl chloride; (6) 2-(N-phenyl-N-benzyl - amino - methyl) - imidazoline monohydrochloride, by reacting 2-(phenylaminomethyl)-imidazoline monohydrochloride with benzyl chloride in alcohol.  Butyl alcohol, dioxane or in benzyl chloride itself may be used as the solvent. Other products which may be prepared by the process of the invention are listed.  Samples have been furnished under Sect. 2 (5) of : (1) 2-[N-(31-oxyphenyl)-N-benzylaminomethyl]-imidazoline hydrochloride; (2) 2 - [N - (41 - chlorophenyl) - N - benzyl - aminomethyl] imidazoline hydrochloride; (3) N-phenyl - N - benzyl - amino - acetamidine - monohydrochloride; (4) 2 - (N - phenyl - N - benzyl - aminomethyl) - tetrahydropyrimidine, all prepared by the process of the invention as set out above.  N - (g  - dimethylaminopropyl) - 2 - anisidine is prepared by reacting g -dimethylaminopropyl chloride with 2-anisidine.
