Title: Duodenal or stomach probe
IPC: A61M23/00
Filed: 1929-10-10
Abstract: 331,453. K³nsztler, M. June 15, 1929, [Convention date]. Probes.-A stomach or duodenal probe comprises a flexible tube a<1> having a screwed socket b<1> at its upper end to which may be secured a screwed nipple q, loose on a stiffening wire m insertable into the tube, or, after the removal of the wire, a nipple on an extension tube. The nozzle e at the lower end of the tube a<1> is furnished with a silk or like thread f, passing through axial and lateral apertures in the nozzle and carrying a plummet d provided with a recess which may be fitted over the nozzle. The wire m is provided with a bulbous end n, a handle o and a collar p limiting the movement of the member q. In use the thread f is drawn up until the plummet d covers the nozzle e, the wire m is then inserted and secured by the nipple q, the end n trapping and holding the thread. The appliance is then inserted into the gullet and the wire m removed, allowing the plummet d to fall. Finally the extension tube is attached and the appliance introduced further into the gullet by pressing or by swallowing on the part of the patient. The plummet is stated to be conveyed rapidly into the duodenum by the action of the stomach. An ulcerous condition of the pylorus is detected by a brownish-black staining of the thread f, in contrast to the yellow staining due to bile.

Title: Improvements in or relating to the manufacture of compositions containing colouring materials
IPC: C09B67/20
Filed: 1925-12-07
Abstract: 267,207. Whatmough, W. H. Dec. 7, 1925. Carbon papers and ink ribbons.-Pigments or lakes are incorporated with oleaginous materials by precipitating them in the presence of a dilute oleaginous dispersion; the products may be used directly in the manufacture of carbon papers or typewriter ribbons, The oleaginous materials which may be used include fats, oils, and waxes, a small quantity of a stabilizing agent, e.g. an alkali or a soap, being added to the oleaginous dispersion if desired. In examples, (1) a blue pigment is formed by mixing solutions of potassium ferrocyanide and ferric chloride (or of ferricyanide and a ferrous salt), an aqueous castor oil emulsion being previously added to one of the solutions; dispersions of carnauba wax, beeswax, mineral oil, petroleum jelly, or linseed oil may be used instead of the castor oil; (2) methyl violet is dissolved in a carnanba wax dispersion, a finely divided white base consisting of barium sulphate and alumina is added with stirring, followed by solutions of tartar emetic, tin chloride, tannin, and sodium carbonate: a soft purple lake incorporating the wax is obtained; and (3) a blue lake is similarly obtained from Victoria blue. In a modification of the process, the oleaginous material may be incorporated in a white base, e.g. by causing solutions of alum. sodium carbonate, and barium chloride to react in the presence of the oleaginous dispersion: a dye may then be struck on the base. Specifications 4040/09, [Class 2 (iii), Dyes &c.]; and 267,625 are referred to.

Patent GB-668078-A (GB)
Title: Sulfonate base lubricating greases
IPC: C10M115/10
Filed: 1948-11-30
Abstract: A lubricating composition comprises mineral lubricating oil thickened to grease consistency with 5-25 per cent by weight based on the whole composition of an oil-soluble metal sulphonate and 3-20 per cent of an oil-insoluble metal salt of one or more alkyl sulphonic acids. The sulphonates may be salts of sodium, lithium, calcium, barium, zinc or aluminium.  The oil-soluble metal sulphonates may be salts of oil-soluble petroleum sulphonic acids while the oil-insoluble metal sulphonates may be salts of one or more of methane, ethane, propane and butane sulphonic acids.  If desired, sulphonates containing an excess of metal base over that required to neutralize the sulphonic acid may be employed.  The lubricating composition may also contain additional ingredients such as antioxidants, rust inhibitors, tackiness agents, viscosity index improvers and extreme pressure agents.  In the examples, mineral lubricating oil compositions containing (1) calcium petroleum sulphonate and calcium ethane sulphonate; (2) barium petroleum sulphonate and barium ethane sulphonate; or (3) sodium petroleum sulphonate and sodium ethane sulphonate, are described.  The Specification as open to inspection under Sect. 91 refers to a grease composition consisting essentially of mineral lubricating oil containing 5 to 25 per cent by weight, based on the total composition, of an oil-soluble metal sulphonate, and 3 to 20 per cent of an oil-insoluble metal sulphonate.  The oil-soluble metal sulphonate may be derived from the petroleum sulphonic acids known as black or green acids.  This subject-matter does not appear in the Specification as accepted.
