Title: Process for the production of mixed salts containing ammoniacal and nitrate-nitrogen jointly
IPC: C05C1/00
Filed: 1930-03-03
Abstract: Mixed salts containing both ammoniacal and nitrate nitrogen are made by treating ammonium nitrate in the solid or hydrated state with liquid or gaseous ammonia to form a solid or liquid solution of the salt therein, and then neutralizing the ammonia with acids such as sulphuric or phosphoric, acid anhydrides, acid salts such as potassium bisulphate, or mixtures thereof.  A dry product is obtained from aqueous solutions by controlling the water content so that the heat of neutralization effects a complete evaporation. The ratio of nitrate to ammoniacal nitrogen can be predetermined by varying the pressure and temperature employed and hence the composition of the initial solution.  According to examples, a solution of ammonium nitrate in ammonia is led into a suspension of ammonium sulphate in ammonium nitrate melt, aqueous sulphuric acid being supplied simultaneously.  Substantially dry ammonium sulphate nitrate is obtained.  The same product is made by spraying a solution of ammonium nitrate in ammonia, and aqueous sulphuric acid from concentric nozzles.  The Specification as open to inspection under Sect. 91 (3) (a) includes the production of ammonium nitrate by using nitric acid for the neutralization.  This subject-matter does not appear in the Specification as accepted.ALSO:Mixed salts containing both ammoniacal and nitrate nitrogen are made by treating ammonium nitrate in the solid or hydrated state with liquid or gaseous ammonia to form a solid or liquid solution of the salt therein, and then neutralizing the ammonia with acids such as sulphuric or phosphoric, acid anhydrides, acid salts such as potassium bisulphate, or mixtures thereof.

Title: Improvements in or relating to the production of blood-coagulating agents
IPC: A61K35/30
Filed: 1945-03-20
Abstract: A blood-coagulating agent suitable for intravenous injection is prepared by converting brain into an aqueous pulp, extracting the pulp with ether, macerating the residue with water whereby the ferments present in the brain split off the active coagulating substance from its complex compound with albumin, separating the albumin, e.g. by precipitation, and evaporating the aqueous solution to dryness.  In the first step brain may be mixed with physiological cooking-salt solution.  The ether extraction and maceration may be effected at 5 DEG C. and the albumin may be precipitated by adding acetone and heating.  The dried residue may be dissolved in a sterile solution and stored in ampoules, or for administration may be mixed with pectin and dissolved in an aqueous sodium citrate solution.

Title: Improvements in breech closure for small arms
IPC: F41A3/26
Filed: 1920-10-19
Abstract: 168,579. Auto-Ordnance Corporation, (Assignees of Payne, O. V.). Sept. 2, 1920, [Convention date]. Breech actions, sliding breech-block.-Relates to automatic guns having a rotary bolt action, and consists in interposing between the rear of the bolt and the return spring, a non-rotary sliding member adapted to be cammed back, against the pressure of the return spring, by the unlocking rotation of the bolt, thereby applying spring resistance to the unlocking rotation, and also adapted to rotate the bolt into its locked position when the bolt returns to its forward position. The invention is shown applied to a rifle of the kind described in Specifications 162,962 and 168,569. Between the rear of the bolt 32 and the return spring 28 is a member 49, shown detached in Fig. 5, having at the front a bevelled projection 50 engaging a similarlv shaped recess 55, Fig. 8, in the bolt when the breech is closed. A lug 54 prevents the member 49 from rotating. The unlocking rotation of the bolt forces the member 49 back against the action of the return spring until the projection 50 is disengaged from the recess 55, and when the bolt returns, the locking rotation is effected after a slight initial rotation by a further forward movement of the member 49. During the longitudinal movements of the bolt, the projection 50 engages a square face on the bolt so that there are no torsional stresses. The firing-pin has a projection engaging a cam surface 37, Fig. 6, at the rear of the bolt so that it is retracted bv the unlocking rotation of the bolt.

Filed: 1925-03-20
Abstract: 234,779. Giesecke, F. May 30, 1924, [Convention date]. Annealing. - In a device for annealing, in which the annealing pot is surrounded by an inert gas during the cooling period, the gas is maintained at a particular vacuum in order that the annealed material will come into contact as little as possible with injurious gases. The pot a is supported in a container b provided with a cover c closed by a liquid seal formed by a liquid d in a trough e. A tank g in the trough e contains the liquid for producing the inert gas, this liquid passing through a container n having means to control the supply to a pipe h having a nozzle i arranged above an evaporating pan k and below a hood m. The container n is provided with a float p actuating a needle valve o, the liquid space of the container communicating with a pipe r into which the end of the pipe h projects. Liquid can only pass from the container n into the pipe h when the vacuum in the pipe is of such magnitude that the liquid in the pipe r rises above the top of the pipe h whence it flows to the pan and is evaporated. The float p may be depressed by a spring-actuated rod x so that liquid may flow into the pipe h independently of the amount of vacuum in the latter. Water is supplied to the liquid seal in the trough e by a pipe y which passes under the cover c. In a modification for controlling the supply of inert gas from a gas supply pipe, the end of the pipe is immersed in a sealing liquid contained in a separate container, the pipe h being then connected to the top of the container.

Patent GB-774439-A (GB)
Title: Improvements in or relating to processes for producing metallisation effects on textile material
IPC: D06Q1/04
Filed: 1955-03-16
Abstract: The adhesion of metallic coatings applied by vapour deposition in a high vacuum to textile material made from natural or artificial cellulose fibres is improved by subjecting the material to a treatment that reduces its swelling property in water before coating it with the metal.  The treatment may be performed by impregnation of the material with a solution of an aldehyde, e.g. formaldehyde, glyoxal and pyroacemic aldehyde, in the presence of a catalyst capable of liberating acid at an elevated temperature and heating it to a temperature of 100 DEG -200 DEG C., or by incorporation in the material of amide-formaldehyde or acetone-formaldehyde resins.  The adhesion of the metal can be further enhanced by reducing the swelling property of the material as described and then providing it with at thin layer of a water-insoluble natural or synthetic resin. Suitable water-insoluable natural resins are shellac and colophony and suitable water-insoluble synthetic resins are (a) film-forming resins obtained by polymerization such as vinyl resins, e.g. polymers or copolymers of vinyl chloride, vinylidene chloride, vinyl acetate, vinyl acetal and vinyl butyral, acrylic and methacrylic resins and polystyrene resins and (b) film forming resins obtained by poly-condensation such as aminoplast ether resins, e.g. ether resins of formaldehyde with ureal or melamine, alkyd, e.g. glyptal, resins, alkyd aminoplast ether mixed resins and ethoxylin resins.  The resins may be applied as solutions in organic solvents or as aqueous emulsions and when resin precondensates are used that cure at an elevated temperature, the adhesion of the deposited metal is further enhanced if the metallized fabric is thus cured.  By way of example are described the treatment and coating with aluminium of various dyed materials and also the treatment and coating of mercerzed cotton poplin with copper and then with gold.
