Title: Air jet yarn entanglement
IPC: D02G1/16
Filed: 1976-08-27
Abstract: 1531527 Texturing yarns J P STEVENS & CO INC 27 Aug 1976 [12 Jan 1976] 35752/76 Heading D1F In jet apparatus 1, formed in a block of metal or plastics material, for entangling the filaments of multifilament yarn(s), one or more such yarns 8 are overfed e.g. by 0.1- 10%, through an inlet 4 and a treatment chamber section 6 of a yarn passageway into which compressed air is injected from introductory and inlet ducts 2 and 3 to create a turbulent stream therein. A smooth surface rod 7 partially extends across the section 6 to provide resistance to the movement of, and thereby relax, the yarn(s) thereover before the emerging yarn(s) pass to take-up rolls (not shown). The blast of air leaving by an air outlet 5 entrains the yarn to be projected to the upper part of the air flow whereat it strikes the curved wall of the passageway to form two vortices. The product 9 may be a single end formed by combining yarns 8 which may be flat or pretextured.
Patent GB-795265-A (GB)
Title: Improvements in or relating to metallic members and corrosion resistant coatings therefor
IPC: C23F15/00
Filed: 1955-12-14
Abstract: An aluminium member, such as the base of an incandescent electric lamp, is provided with a lubricating and corrosion-resisting coatting comprising sperm whale oil and a surfactant.  The surfactant may be a condensation product of iso-octyl phenol or nonyl phenol and ethylene oxide.  The coating may be applied by dipping the heated member in an aqueous emulsion of the blend of sperm whale oil and surfactant and then drying the member.  A deodorant or masking compound, such as a high-boiling ester oil, may be added to the aqueous emulsion.  It is stated that the coating is initially wet and mobile and is easily reemulsified away with water.  However, over a period of about 24 hours, the coating reacts with oxygen in the air and, as a result, hardens and becomes water-repellent.  The oxidation may be accelerated by incorporating in the sperm whale oil-surfactant blend, before formin the aqueous emulsion, an oxidation catalyst such as one or more of the naphthenates or linoleates of iron, cobalt, manganese, zinc or lead.  Cerium or vanadium naphthenates are also mentioned as oxidation catalysts.  For comparison purposes, an aqueous emulsion comprising hydrogenated sperm whale oil, toluene and sodium heptadecyl sulphate is described.

Title: Process for the production of high-grade steel
IPC: C22C33/04
Filed: 1931-12-29
Abstract: Steel contains less than 0,12 per cent of carbon, 0,6-1,0 per cent. of silicon, 0,5-2 per cent of copper with or without 0,1-1,5 per cent of chromium.  Absorption of oxygen by the molten steel during refining is suppressed, for example, by a high manganese content in the open-hearth process, and by incomplete dephosphorization in the basic Bessemer process.

An electric motor has an external rotor comprising a laminated core 1 with a squirrel cage winding having bars 2 and rings 3. Ventilation ribs 4 and outer rings 5, forming a jacket, are mounted on the members 3 as well as a hub 6 receiving a shaft 8. The parts 2, 3, 4 and 6 may be produced by a single pressure casting operation, the jackets being cast at the same time or fitted later. The hub 6 supports a steel bush 7 which is serrated for better anchorage and forms a secure seating for the shaft 8. The casting is provided with points 9 which engage and compress the laminations 1 during the casting operation. Air outlet apertures may be formed in the jackets 5. In a modification, the two separate jackets are replaced by a single jacket extending over the laminations, the squirrel-cage rings at one end being joined to the hub by means of a thin closure plate, Fig. 2 (not shown). The internal winding assembly is mounted on a tube carrying the machine bearings. In another arrangement, the laminated core is replaced by a solid iron or steel ring within a cylindrical jacket which is extended to form the end-rings of the squirrel cage, Fig. 3 (not shown). The jacket may be provided with internal axial ribs on which the iron or steel ring rests, and a separate end-ring of the squirrel-cage winding is offset from the solid core to allow for the passage of air, Fig. 4 (not shown). Additional rings on the rotor reduce the leakage of flux.

Abstract: The invention comprises the N-penta-acetic acids of N - b  - aminoethyl - 1 : 2 - diaminocycloalkanes, particularly the cyclopentane and cyclohexane derivatives, and water soluble monovalent cation salts and polyvalent metal chelates thereof. Such compounds are prepared by reacting the said triaminocycloalkanes with compounds such as monohalogen (e.g. chloro- or bromo-) acetic acids, their salts, esters, amides and nitriles, glycolic acid nitrile, or formaldehyde with alkali or hydrogen cyanide; where appropriate, the reaction product is hydrolysed.  In the case of cyanomethylation, such hydrolysis may be effected simultaneously or subsequently. The penta-acid itself may be isolated from the pentasodium salt solution by a combination of acidification (HC1), ion-exchange and Pb salt/H2S methods.  Many metals which may be chelated are mentioned, but Ca, Fe11 and Fe111 are exemplified.  The N-b -aminoethyl-1:2-diaminocycloalkanes required are obtained by reacting 2-aminocycloalkane sulphuric acid with ethylenediamine (exemplified), or cycloalkane-1:2-diamine with ethyleneimine or with 2-aminoethyl chloride.ALSO:Ascorbic acid in fruit juices is stabilized by N-penta-acetic acids of N-(b -amino-ethyl)-1:2-diaminocycloalkanes (e.g. cyclopentanes or cyclohexanes) and water-soluble salts thereof such as the sodium salts.

[Also in Division B3] A rivet comprises a tube 10 having a flange 12 and threads 17, the threads engaging a shank 13 provided with threads 15 and a drill tip 19. The threads 15, 17 are left handed and the space between the shank and the tube is filled with a plastics material 18 such as a thermosetting plastics. Projections 14 enable the shank to be gripped in the chuck of an electric drill in order to drill a hole through the members 30, 31. When the lower surface of the flange 12 abuts the member 31 a fluted portion 11 of the tube wedges the rivet in the hole and the left hand threads unscrew the shank 13. In so doing, the drill tip deforms the tube 10 against the member 30 before breaking off at a weakened portion 16. The tube 10 is made of metal and the plastics material forms a seal to prevent leakage through the rivet. The weakened portion may be omitted and the rivet fastened until the threads 17 have been stripped, the shank then being driven through the rivet and discarded. The entire interior and exterior surfaces of the rivet may be coated with a thermosetting plastics material. In a modification, the fluted portion is omitted and locking tabs which bite into the member 31 are formed on the flange.
