Patent GB-143582-A (GB)
Abstract: 143,582. Shoobridge, R. H., and Borg, H. M. June 27, 1918. Stop-gear.-An internal - combustion engine is automatically stopped by interruption of the ignition circuit if the pressure of the lubricating-oil fails. A metal ball 2 is raised in a tube by pressure of oil which enters the tube at 3 and leaves it at 4. If the pressure fails, the ball rests on two electric contacts 10, 11 and interrupts the ignition circuit. The contacts may be at the upper end of the tube, so that the ball breaks a circuit when it falls. A switch is provided to render the device inoperative when starting the engine.

Patent GB-747733-A (GB)
Title: Method for forming lead coatings on ferrous metal surfaces
IPC: C23C18/31
Filed: 1953-05-22
Abstract: A non-electrolytic method of forming a lead coating on a ferrous article comprises treating the article with an aqueous solution of a lead salt of an aliphatic polybasic hydroxy acid, such solution having a pH less than 7 and a lead ion concentration of 3-50 grains per litre.  Lead salts of malic, tartaric, citric, maleic and diglycollic acids may be used and the solubility of such salts may be increased to the required amount by increasing the free acid content of the solution or, preferably, by the presence in the solution of ammonium or alkali metal salts of any of these acids.  The solution may be applied by immersion, spraying, brushing or flow-coating. Addition agents such as dextrose, maltose, sucrose, lactose, dextrin, starches, casein, bone glue, albumin, gelatin, zein, tannic acid, salicylic acid, pyrogallic acid, gellic acid, aldehydes, furfurals, phenols, cresols, aloin, goulac, licorice, resorcinols, naphthols, gums and amines may be employed.  The solutions may be used at 70 DEG F. to boiling point, preferably at 160 DEG F. to 210 DEG F.  Other components of the solution may include trivalent elements such as aluminium and iron and ammonium and alkali metal fluorides and bifluorides.  The concentration of iron ions in the solution may be controlled as described in Specification 747,734.  The lead coating may be chromated, oxalated, sulphated, phosphated, painted or oiled.
Patent GB-1018342-A (GB)
Title: Production of purified preparations of the kallikrein inactivator
IPC: A61K38/57
Filed: 1964-04-08
Abstract: Solutions containing kallikrein inactivator are purified by addition of an aqueous solution of a polyphosphoric acid or water-soluble salt thereof to effect precipitation of a complex of kallikrein inactivator, which is then decomposed by dissolving it in a salt solution stronger than 1%. w/v, or an alkali metal hydroxide solution; the resulting salts are then separated from the kallikrein inactivator solution to give a purified solution, which may be lyophilized to yield a solid product.  Preferred salts of polyphosphoric acid are those of alkali metal or ammonium, while the salts used to decompose the complex may be sodium or ammonium chloride.  The separation of the salts from the kallikrein inactivator solution may be by dialysis or ion exchangers.  Suitable sources of the initial impure solution of inactivator are animal organs such as parotid, spleen, lymph, lungs, liver, or pancreas.

Carbon fibres are made by heating a nitrogenous long chain charring carboniferous material at a rate of temperature rise of < 1‹ C./min. to a first temperature, e.g. 1000‹ C., whereby the fibre is modified by molecular chemical bond formation to a stable intermediate form and subsequently heating the fibre to a second higher temperature, e.g. 2500‹ C., whereby the fibre is modified to a graphitic or polygraphitic structure of high strength and high elastic modulus. The heating rate in the second stage may be 30-45‹ C./min. The fibre may be initially polyacrylonitrile. The heating may be performed in an inert atmosphere, e.g. N 2  or Ar. The fibre may be wound on a frame during heating. The carbon fibre may be embedded in a resin matrix.

Abstract: 878,414. Cutting apparatus; treating edges of fabrics. HARRIMONDE Ltd. Feb. 20, 1959 [March 10, 1958], No. 14563/61. Divided out of 878,413. Classes 31 (1), 31 (2) and 42(1). Apparatus for forming a button-hole in fabric containing synthetic thermoplastic material in which fabric a button-hole has been stitched in outline comprises a knife 1 having a cutting edge 6 of button-hole shape formed with an eye 7 for cutting inside the stitched outline to form the hole, the knife being held in position in a block 2, and means for heating the knife so that as the fabric is cut only the edges of the fabric so formed are fused or partially fused. As shown, the knife is heated by electrical heating elements 3, 4; alternatively, the knife may be heated by other means, e.g. a gas flame or hot water or the knife itself may constitute the electric heating element. A cutting block is used to press the fabric on to the cutting edge of the knife, and the cutting block and the knife may be mounted at the ends of a pair of crossed levers which are moved pivotally with a scissors action. Molten portions of fabric cut by the eye 7 flow through a passage 20 in the knife and thence into an aperture 21 in the block 2.

Title: Process for the production of iron or steel from ores in a furnace
Inventor: AULD JAMES BEATTIE
IPC: C21B13/00
Filed: 1966-04-01
Abstract: Iron ore and flux are introduced into a furnace together with a carbonaceous material and an oxidant, whereupon the ore is melted and reduced and the resultant metal is covered with a slag layer. At least a part of the carbonaceous material is injected into the bath, one portion being introduced into the metal and the other into the slag layer, the proportions being varied so that a desired carbon content of the iron is obtained. The carbonaceous material may be solid, liquid or gaseous, but a fluid hydrocarbon is preferred. A stream of secondary hydrocarbon, which need not be so low in sulphur as the primary hydrocarbon, may be introduced as fuel above the bath together with an oxidant, while effluent gases from the furnace may be used to pre-heat and/or pre-reduce the ore.
