Abstract: The invention comprises compounds of the formula <FORM:0752097/IV(a)/1> wherein R and R1 are hydrogen atoms or alkyl groups having from 1 to 4 carbon atoms, and non-toxic salts thereof. They are obtained by acylation of the corresponding triiodoaminophenylalkanoic acids (the preparation of which is described in Specifications 655,096 and 710,993) with the appropriate acid or derivative thereof such as the anhydride or acid halide and, if desired, converted to non-toxic salts. Preferably the anhydride in the presence of a strong acid such as sulphuric or perchloric acid is employed.  When R1 represents hydrogen the formylation can be carried out with formic acid and acetic anhydride.  Sodium, diethanolamine and methylglucamine salts are referred to.  A list is given of suitable b -(2,4,6-triiodo-3-aminophenyl) propionic acid starting materials (obtainable by iodination of the corresponding phenyl derivatives) containing as alpha-substituents methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec.-butyl and tert.-butyl radicals. N-formyl, N-acetyl, N-propionyl, N-butyryl, N-isobutyryl, N-valeryl and N-isovaleryl derivatives of these acids are referred to.  In examples: (1) and (2) a -ethyl-b -(2,4,6-triiodo-3-acetaminophenyl) propionic acid is prepared by reaction of a  - ethyl - b  - (2,4,6 - triiodo-3-aminophenyl) propionic acid with acetic anhydride in the presence of (1) sulphuric acid and (2) perchloric acid and purification as its morpholine salt; (3) the product of Examples (1) and (2) is reacted with sodium hydroxide to form the sodium salt; (4) 2-ethyl - b  - (2,4,6 - triiodo - 3 - formamidophenyl) propionic acid is prepared by treatment of the amino-acid with formic acid and acetic anhydride.  In a generally similar manner to (1) there are prepared from the appropriate (2,4,6 - triiodo - 3 - aminophenyl) alkanoic acids and acid anhydrides: (5) a -ethyl-b -(2,4,6-triiodo - 3 - propionamidophenyl) - propionic acid; (6) b  - (2,4,6 - triiodo - 3 - acetamidophenyl) - propionic acid; (7) b  - (2,4,6 - triiodo - 3 - propionamidophenyl) - propionic acid; (8) a  - butyl - b  - (2,4,6 - triiodo - 3 - acetamidophenyl - propionic acid; (9) a  - propyl - b - (2,4,6 - triiodo - 3 - n - butyramidophenyl) - propionic acid; (10) a  - methyl - b  - (2,4,6 - triiodo - 3 - n valeramidophenyl) - propionic acid.  The products are useful in cholecystography. Starting materials for Examples 1, and 6 to 10, are prepared by treatment of the appropriate 3-aminophenylalkanoic acids with iodine monochloride and hydrochloric acid.

Abstract: In a preferred embodiment a lighting system contains a cathode 12 with an external surface 34 coated with an external cathode film 40 for the emission of electrons. A first anode 14 runs inside the cathode 12 to heat up the cathode in order to emit electrons from the external surface 34. A second anode 16 is arranged outside the cathode 12 to accelerate the electrons which are emitted from the external surface 34 of the cathode. A bulb body 18 surrounds the cathode 12, the first anode 14 and the second anode 16 in a hermetic seal. The bulb body contains a predetermined gas composition, the atoms of which are ionized by the electrons emitted by the cathode. The ionized atoms in the gas composition emit rays in the ultraviolet bandwidth of the electromagnetic spectrum. The bulb body 18 is coated with a fluorescing material 20 to trap the ultraviolet energy originating from the ionization of the atoms in the gas composition. The fluorescing material 20 emits rays in the visible bandwidth in the electromagnetic spectrum and emits a visible light. <IMAGE>

Title: Improvements in the manufacture of diethers from either polyoxyalkylene diols or monoethers thereof
Filed: 1948-01-02
Abstract: Aliphatic diethers of polyoxy-1,2-propylene diols are made by reacting with a dialkyl sulphate or an aliphatic halide in presence of an alkali metal hydroxide, a polyoxy-1,2-propylene diol or an aliphatic monoether thereof, which diol or mono-ether has an average molecular weight such that the portion attributable to oxy-1,2-propylene groups is at least 800.  Suitable starting materials are described in Specification 601,604.  1-2 mols. of dialkyl sulphate per hydroxy group in the starting material and 2 mols. of alkali metal hydroxide per mol. of dialkyl sulphate are preferably used.  The temperature is maintained between 90 DEG  and 100 DEG  C.  About 4 mols. of organic halide are employed per hydroxyl group with about 1.25 mol. of alkali metal hydroxide per mol. of organic halide, and the temperature is 100-140 DEG  C.  A diluent for the reaction mixture may be used, e.g. dibutyl ether or toluene. The etherifying aliphatic group may contain up to 12 carbon atoms. Examples are described of the preparation of the following ethers: di-ethyl, ethyl butyl, butyl-n-propyl, dibutyl, butyl-n-octyl, butyl-n-dodecyl; their physical properties are described.  They are useful as lubricants, if desired in admixture with petroleum oils (see Group III), as hydraulic fluids (see Group XXIX), or as cutting oils.ALSO:Aliphatic diethers of polyoxy-1,2-propylene diols (see Group IV(a)) having an average molecular weight excluding the terminal ether group of at least 800, are useful alone or with petroleum oils as lubricants, especially for low temperature work, or as the lubricating component of low temperature greases, or as cutting oils.

Title: Improvements in automatic variable speed drive transmission gearing
IPC: F16H29/04
Filed: 1928-01-03
Abstract: 283,115. Zahnradfabrik Akt.-Ges. Jan. 3, 1927, [Convention date]. Variable-speed ratchet gearing suitable for vehicles is arranged round an axis about which the whole arrangement may revolve for a. highest speed. Gears a<10>, Figs. 1 and 2, carried by a casing e kept from turning backwards by a detent c<4> are constantly in mesh with a gear f<1> fast on a driven shaft f<3>. The gears a<10> are driven in one direction through ratchet clutches a<7> by levers a<1>, which are held against a multiple cam c bv springs a<5>. The cam c drives the levers, being slidably feathered on a driving-shaft f<2>. The cam c is coned so that as it slides, the amplitude of swing of the levers a<1> and thus the speed transmitter are varied. The speed may be controlled automatically by a governor i acting on the cam. When the load falls sufficiently the gearing turns solid. Manual control may be effected alternately through a lever l<2> and l<3>. A suitable reversing-gearing is shown at g<1>. The Specification as open to inspection under Sect, 91 (3) (a) comprises also an epicvclic form shown in Figs. 3 (Cancelled) and 4 (Cancelled); the casing e which carries the gears a<10> is fast to a. driving flywheel d. The cams c<1> do not normally rotate and are kept from turning rearwardly by a. detent c<4>. The central gear f<1> is fast on the driven shaft f<2>. Levers b have sliding connections with oscillators a<1> which drive the planet gears a<10> through ratchet clutches a<7>. The cams c<1> are invariable and the speed is varied by displacing the levers b relatively to the oscillators a<1>, This may be done automatically by centrifugal weights i<2>, Fig. 3 (Cancelled). When the load falls sufficiently, the cams c<1> are carried round with the gearing solid.. Alternative manual displacement of a ring h which carries the levers b is effected through a linkage k when a disc l is slid axially by a lever l<2>. This subject-matter does not appear in the Specification as accepted.

Abstract: 508,849. Separating oils from residues containing solids. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.). Jan. 3, 1938, No. 137. [Class 91] In a process for recovering oils from residues by adding a diluent and separating the solids mechanically, the diluent added consists of liquid or liquefiable hydrocarbons containing 4 or more carbon atoms boiling below 325‹ C. and consisting of one or more fractions of which the hydrogen-carbon ratio is at least 15.5/100 for hydrocarbons boiling 200‹ to 325‹ C., at least 17/100 at 200‹ to 300‹ C., and at least 17.5/100 at below 200‹ C. After dilution, the mixture is rapidly heated to above 120‹ C. to avoid separation of asphalts and resins, and is filtered at that temperature. Destructive hydrogenation, distillation, or solvent extraction residues from coal, peat, shale, wood, tar or oil, or pressure extracts from coal, may be treated. Diluents specified are butane, pentane, heptane, octane and benzines or illuminating oil fractions of the desired C/H ratio, obtained by the Fisher-Tropisch process. The process, including filtration may be effected under pressure. The filtration may be effected in the presence of hydrogenated cyclic compounds, or bleaching earths, kieselguhr, light ashes, or coke which may be pre-treated with acids or acid salts. Specifications 312,383, [Class 91], 417,757 and 497,607 are referred to.
