Title: Improvements in the preparation of compounds having a narcotic effect and the products obtained thereby
IPC: C07D489/04
Filed: 1951-11-09
Abstract: The invention comprises salts of polybasic acids with homatropine and with one or more morphine alkaloids or their narcotic derivatives having the morphine ring-system.  The salts are made by dissolving the components in a common solvent (or separately and then mixing) and isolating the product by evaporation or precipitation. Alternatively they may be prepared by double decomposition, e.g. from a barium salt of the acid and the sulphate of the base.  Examples show the production of dihydrohydroxycodeinone homatropine terephthalate, dihydromorphinone homatropine citrate, morphine homatropine malonate, dihydrocodeinone homatropine tartrate, codeine homatropine succinate, ethylmorphine homatropine aconitate, dihydrocodeine homatropine phthalate and codeine homatropine fumarate.  Other specified acids are camphoric, phenoldisulphonic, benzenetrisulphonic, salicyldisulphonic, saccharic, sulphuric, sulphurous and phosphoric.ALSO:Narcotic compositions contain a salt of a polybasic acid with homatropine and with one or more morphine alkaloids or their narcotic derivatives having the morphine ring-system.  Preferably such salt is mixed with a larger amount of a simple salt of the narcotic base.  The compositions may be in the form of tablets, capsules, solutions or suppositories and may be administered by injection, per oz or into the rectum.  The usual binders, diluents, lubricating agents and stabilizers may be present. As an example a mixture of dihydrohydroxycodeinone homatropine tetaphthalate, dihydrohydroxycodeinone hydrochloride, lactose, starch, dextrin, a dyestuff and water is granulated with methanol, and the talc and starch added; the mixture is converted into tablets. Two or more narcotic bases may be present in the composition.  Other specified double salts are dihydromorphinone homatropine citrate, morphine homatropine malonate, dihydrocodeinone homatropine tartrate, codeine homatropine succinate, ethylmorphine homatropine aconitate, dihydrocodeine homatropine phthalate and codeine homatropine fumarate.  The salts may also be derived from camphoric, phenoldisulphonic, benzenetrisulphonic, salicyldisulphonic, saccharic, sulphuric, sulphurous or phosphoric acid.

Title: Paper sizing agents
IPC: D21H17/14
Filed: 1927-10-06
Abstract: 309,383. Marks, E. C. R., (Alox Chemical Corporation). Oct. 6, 1927. Drawings to Specification. Sizing and weighting.-Organic hydroxy-acids of high molecular weight, insoluble in petroleum and suitable for use in sizing paper are produced continuously from a petroleum distillate which may be of 36-40‹ BÚ. and mostly distilling between 260 and 360‹ C. by oxidizing the oil in liquid phase with air or other oxidizing gas at 120-155‹ C. and under pressure (200-350 lb.), with or without a catalyst such as a manganese copper or iron compound (manganese oleate being mentioned) until a material quantity not greater than 10 per cent of the hydroxy acids are produced, the acids being separated treated with steam at above 150‹ C., and converted into soaps. The soaps are added to the paper stock with the addition of a salt such as an, aluminium salt. The oxidized material passing to the still consists mainly of carboxylic and hydroxycarboxylic acids and ketones of high molecular weight. It is heated to about 150‹ C. for instance by a steam coil (water and ketones, passing off) and steam is then passed through the material to expel all volatile matter. After cooling, some heavy sludge may separate and is carefully drawn off from the " size acid." The " size acid " is dissolved in aqueous caustic soda or sodium carbonate. The soap solution is added to the paper pulp in the beating-engine, followed by a suitable precipitant such as aluminium sulphate or alum. If desired the soaps may be made with an excess of alkali and bleached with chlorine, the excess of alkali being then neutralized by an acid. The process may be continuous.

Title: Improvements in the manufacture of articles from alloys
IPC: C23C10/00
Filed: 1928-09-15
Abstract: 326,518. Johnson, J. Y. (I. G. Farbenindustrie Akt.-Ges.). Sept. 15, 1928. Modifying chemical characters of metals.- Articles of at least 0.05 mm. thickness consisting of alloyed metals free from tungsten and zirconium, particularly thin articles which cannot be satisfactorily cast, are made by constructing an article of the desired shape of one or more metals of the desired alloy, and causing the remaining metal or metals of the alloy to diffuse into the article. The diffusion may be complete, or only to a certain depth, in which case, if the metal is alloyed on one side only, the unimproved portion of the base metal may be removed by mechanical or chemical means. At places where greater thickness is required, the base metal may be left unattacked or may be originally made thicker. The diffusion may be effected by heating the article in metal powder, and if desired further heating after removal from the powder; or coatings may be deposited electrolytically and the coated articles afterwards heated. Base metals and coating metals may include nickel, cobalt, iron, copper, aluminium, magnesium, manganese, molybdenum, silver, and alloys thereof. Alloys containing silicon may also be made. Iron may be embedded in cobalt, heated in hydrogen, and further heated after removal; nickel may be electroplated with chromium and heated; iron may be electroplated successively with nickel, chromium, and iron and heated; or iron may be heated at 300‹-400‹ C. in hydrogen containing silicon tetrachloride whereby a layer of silicon is formed which is caused to diffuse by heating in hydrogen at 900‹ C.

Filed: 1968-06-05
Abstract: 1,203,306. Determining impulse response. NORTH AMERICAN ROCKWELL CORP. June 5, 1968 [June 5, 1967], No.26849/68. Heading G1U. [Also in Division H4] In an automatically adjusting equalizer the impulse response of the transmission channel is determined by correlating previously received data in shift register 52 Fig. 1, with the incoming signal from sampling device 51 in the cross correlators 53 a-n to produce signals hi to hn which are proportional to the amplitude of the impulse response at the sampling instants of the data channel immediately following an impulse. The impulse response signals hi to hn are combined in summing device 72, with signs, provided by multipliers 71, derived from the previously received data as stored in shift register 52. The combination signal is subtracted from the received signal in 73 in order to reproduce the originally transmitted signal. The transmitted signal is made pseudo random at the transmitter either by mod 2 adding the data signal to a pseudo random sequency of pulses, or by passing the signal through a linear sequential coding network. At the receiver the inverse operation is performed using a similar pseudo random generator 75 or an inverse coding network, to retrieve the original data. The transmitted pulses may be shaped, e.g. by a cos<SP>2</SP> fn. to reduce distortion. In a modification, Fig. 8 (not shown) in which two data streams are transmitted by modulation of two carrier signals in quadrature, the received data in each channel is correlated not only with the received signal of its own channel but also with the received signal of the other channel in order to define an effective impulse response due to cross talk, and to derive a correction signal to eliminate cross talk.
