Title: Improvements relating to blood coagulation test reagents
IPC: G01N33/86
Filed: 1961-03-30
Abstract: A substrate plasma, useful in the assay of blood coagulation factors in human beings and other species, is prepared by treating blood plasma from a first species of animal with an adsorbent (as hereinafter disclosed) to remove therefrom all but a small residual amount of one or more blood coagulation factors and adding to the treated plasma a small proportion of a serum from a second species of animal containing antiobodies immunologically specific for the said coagulation factors to remove the small residual amount of the said factor or factors from the plasma. The serum is obtained by injecting an animal of the second species with a concentrate containing the said one or more coagulation factors which has been prepared from the blood plasma or serum of an animal of the first species, drawing blood from the animal after an interval of time in which the antibodies have developed and separating the serum from the blood so obtained. The concentrate is prepared by treating plasma or serum from the first species with an adsorbent to adsorb one or more coagulation factors therefrom, separating the adsorbent from the plasma or serum, eluting the adsorbed factors and concentrating the eluate to obtain a concentrate of said coagulation factors. Specified adsorbents are calcium phosphate, barium sulphate, asbestos and an ion exchange cellulose derivative.  Aqueous solution of sodium citrate may be used for elution.  The substrate plasma mixed with thromboplastin, calcium chloride and a barbitone buffer is lyophilised for storage and is reconstituted with distilled water for use.

Filed: 1955-04-26
Abstract: The invention comprises dyestuffs of formula <FORM:0806166/IV (c)/1> where X is H or Halg. and the azo group is attached in the 4-, 5-, 6- or 7-positions and their metal complexes.  The indazole nucleus may be substituted in the 4-, 5-, 6- and 7-positions by halogen atoms, alkyl, alkoxy, nitro, sulphonamido and acylamino groups, the last of which must be m- or pto the azo group.  They are made by diazotizing an appropriate aminoindazole, coupling, preferably in an alkaline medium, with resorcinol and metallizing the product. Indicated metals are those of atomic weight 51-65, specified being Cr, Mn, Fe, Ni and Cu, metallization being effected in known fashion. The metal complexes may be coupled once or twice with diazo compounds of sufficient strength and the products yield black dyeings on fibres when made from 7-amino- and brown dyeings from 4-, 5- and 6-amino-indazoles which are water-insoluble.  They may be mixed with nitrosamines and diazoamino derivatives and used in known printing processes.  The nitrosamines and diazoamino compounds preferably contain substituents such as halogen atoms and alkyl, alkoxy, aryloxy, nitro, sulphonamido, trifluoromethyl, acylamino and sulphone groups.  In examples, dyestuffs are made from 4-chloro-7-amino-, 6-amino- and 4-amino-5-methylindazoles and cobalt, chromium and copper complexes are obtained therefrom.  The metal dyestuffs thus obtained are used as coupling agents in printing pastes for cotton together with conventional components, there are also present diazoamino compounds derived from 4- and 5-chloro-2-amino-, 4-dimethylsulphonamido-2-amino- and 4-chloro-3-amino-toluenes, 4-chloro-2-aminoanisole and dianisidine as diazo components and N - (2,4 - dichloro - 6 - carboxyphenyl)- and N-(2-carboxyphenyl)-glycines and N-hydroxyethyl-anthranilic acid.

Title: Improvements in or relating to electrical oscillating systems
IPC: H01J25/68
Filed: 1938-04-21
Abstract: 517,264. Electric resonators ; valve circuits. STEVENS, A. H. (Leland Stanford Junior University, Board of Trustees of). April 21, 1938, No. 11978. [Classes 39 (i), 40 (iii) and 40 (v)] An oscillating system or electric resonator comprises a substantially-closed hollow conductor in which standing electro-magnetic fields are developed, the field oscillating in such a way that the region of maximum magnetic energy is radially located with respect to the region of maximum electric energy. A valve may be located in the resonator, and the oscillations produced may be fed to an antenna or used for therapeutic heating of tissues, for heating an induction furnace or for accelerating electrons in an X-ray tube. The resonator may comprise a cube, a sphere, a cylinder, or certain other quadric surfaces, and may be partitioned in accordance with the mode of vibration desired, Figs. 4-8 (not shown). The oscillator shown in Fig. 1 has a cylindrical wall 1, flat ends 2, 4, a central partition 17 perforated with holes 19, and a plate 6 which is perforated with holes 16 and supported on pins 9. The equivalent circuit is shown in Fig. 9. The anode of an " acorn " valve 20 is connected to the plate 17, and so through lead 34 to the anode battery ; the cathode is connected to the plate 6 and so through lead 35 to battery negative ; the grid is connected through a lead 30 to a grid leak 41, Fig. 9, or a grid-bias battery, the lead 30 being capacitively connected to the end plate 2 through insulated plates 31 ; and the heater is connected to a source of current through twisted leads 26, the oscillations being by-passed through a pair of capacitive strips 27. The device may be coupled to an antenna by an inductive loop 37. The relation between the wave-length and the magnitude of the resonator is calculated for several geometrical forms in the Specification. The oscillation-generator may be external to the resonator, and the plates 6, 17 may be replaced by a wire loop 7. A plurality of valves 20 may be operated in parallel. The resonator may be evacuated and the envelopes of the valves removed. A person may be located inside the resonator for treatment by the high-frequency oscillations generated by an oscillator external to it, Fig. 10 (not shown). Free electrons from a suitable source may be accelerated by the oscillating field produced by valves 53, Fig. 12, in an evacuated resonator 49, their directions being reversed at each end by the fields of magnets 51, 52 so that they follow a path p with increasing velocity until they are projected into a chamber 54. They may then be used for producing X-rays, Fig. 11 (not shown). Specification 517,311 is referred to.

Patent GB-581153-A (GB)
Title: Production of amino-hydrazines
IPC: C07D237/32
Filed: 1944-06-28
Abstract: Aminohydrazines of the formula NH2RN2H3 are obtained by reacting with hydrazine a substituted ester of the formula ANRX, where AN is a dicarboxyacylimido group, e.g. diacetimido, succinimido or phthalimido, X a negative radical of a strong acid, e.g. a halogen, hydrogen sulphate or para-toluene sulphonate and R an aliphatic radicle.  The latter may be branched chain or cycloalkyl and may be substituted, e.g. with a hydroxy group.  The chain may also be interrupted by oxygen, sulphur or other atoms or by an aryl radicle. An intermediate hydrazinohydrazide compound may be first formed, but this is readily hydrolysed with aqueous mineral acid to the aminohydrazine and, for example phthalhydrazide.  In the example, potassium phthalimide and hexamethylene dichloride are heated under reflux in an atmosphere of nitrogen.  The product is distilled and the residue extracted by light petroleum, from which 6-chlorohexyl phthalimide is crystallized.  The bromo compound can be prepared similarly.  The 6-chlorohexylphthalimide is warmed with alcoholic hydrazine hydrate solution, and the solution then acidified with hydrochloric acid and refluxed.  The phthalyl hydrazide is filtered off and the filtrate further acidified with hydrochloric acid, evaporated in vacuo and hydrazine dihydrochloride removed as it forms.  The residue is dried by azeotroping with benzene and recrystallized from alcoholic hydrogen chloride giving 6-aminohexylhydrazine dihydrochloride.  The product may also be recovered by distillation or extraction.  Residual hydrazine may be removed by treatment with benzaldehyde which reacts preferentially with the organic hydrazine product to give a benzalazine.  Other examples of substituted esters which may be used are 2-chloro-ethyl-, 3-chloropropyl-, 4-chlorobutyl-, 5 - chloro - p - methylamyl-, 4 - chlorocyclohexyl, o  - chloro - p - xylenyl-, 2 - chloroethoxyethyl - phthalimides and the corresponding bromo derivatives.  They may be made by reacting an aliphatic dihalide with phthalimide in the presence of anhydrous alkali, e.g. potassium carbonate.  An anhydrous solvent such as alcohol may be used.  In the Provisional Specification, the production of compounds of the formula NH2RN(NH2)RNH2 by reacting the phthalimide derivative with a small amount of hydrazine is described.
