Patent GB-992768-A (GB)
Title: Method of decarburising steel
Inventor: GOODEVE SIR CHARLES FREDERICK
IPC: C21D3/04
Filed: 1963-02-18
Abstract: A method of decarburizing steel sheet material comprises coating rolled and cleaned steel sheet material with a thin layer of a finely divided solid material, the oxygen potential of which is high enough at the annealing temperature of the steel sheet material to oxidize the carbon in the surface layer of the steel, then closely packing the coated sheet material and annealing it in this condition.  The close packed sheet material may comprise stacked sheets or closely coiled strip.  A suitable coating is iron oxide, e.g. in the form of rouge or Rif ore. The finely divided solid material may be applied to the sheet by spraying on to the aqueous suspension of the said material, by electrophoretic deposition from a suspension in a suitable organic medium, or by roller coating the strip with a mixture of dry iron oxide and an adhesive.  The amount of material applied is preferably such as to give a ratio of oxygen to the carbon contained in the strip proportional to CO2.  The annealing is carried out for 5 hours at a temperature of 680-750 DEG C. Annealing is preferably carried out in an oxygen-free inert atmosphere or a sub-atmospheric pressure. After annealing the sheet material may be pickled to remove any remaining solid material.

Abstract: 1455606 Change-speed control ZAHNRADFABRIK FRIEDRICHSHAFEN AG 13 Feb 1974 [14 Feb 1973] 06486/74 Heading F2D In a manually controlled motor-vehicle transmission 3, wherein only the first ratio 1 is driven through a fluid coupling or converter 2, first ratio is automatically established when vehicle speed falls below a predetermined value, so that subsequent acceleration is always through the fluid coupling and first ratio irrespective of the setting of the manual selector. Reverse and three forward ratios are established by energizing electro-magnets 40 ... 43 respectively, under control of an exclusively manual selector switch 20, which energizes reverse and first ratio magnets 40, 41 directly, and second and third ratio magnets 42, 43 through relays 52, 53 in conjunction with a contactor 9 actuated by an output driven governor 7. Action is as follows, assuming that third ratio is established and vehicle speed is above the said value. The third ratio magnet 43 is energized from the manual switch 20 through contact 60, relay contact 53a and lead 33a. When vehicle speed falls below the predetermined value, the grounded contact 9 of the governor 7 contacts strip 11 (position shown), energizing the winding 53c of the relay 53, moving downwards contacts 53a, 53b, the former de-energizing the third ratio magnet 43 and completing a hold-on circuit, the latter, 53b, energizing the first ratio magnet 41, so that subsequent acceleration of the vehicle is in the fluid-driven first ratio. The relay winding 52c acts similarly if second ratio is engaged, but its contact strip 10 is shorter than 11 and contacts at a lower speed.

Patent GB-1602204-A (GB)
Title: Method of making hollow bodies by winding
IPC: B29C53/82
Filed: 1978-02-20
Abstract: For producing elongated hollow bodies which are round in cross-section, numerous filaments (6) are clamped parallel to one another distributed round the internal circumference of the body (30) to be produced, so that a winding core results which is subsequently wound, so that it represents a lost core. During winding, the thus longitudinally clamped filaments of the winding core are, because of the winding tension, deflected inwards so that the hollow body takes on the form of a hyperboloid. By cutting through a hollow body of this kind in its centre, poles can be produced which serve, for example, for carrying electrical lines. These poles are distinguished by an especially high strength. <IMAGE>
