Title: Improvements in and relating to an automatic milling machine
IPC: B23D65/04
Filed: 1947-04-23
Abstract: 635,078. Milling saws; feed-motions. HIPPENMEYER, W. April 23, 1947, No. 10895. Convention date, May 3, 1946. [Class 83 (iii)] In a machine for milling jeweller saw blades, the blade wires 34 are fed by two rollers 35, 36, to a rotary milling-cutter 3 which is disposed between guides 23, 24, and is reciprocable towards and away from the blade wires, an automatic mechanism acting on the rollers 35, 36, so as to give them alternately a number of quick long feed steps and a number of slow short feed steps corresponding respectively to the toothless ends of the blades and to the rows of teeth. The feed roller 35 is mounted on the spindle of a toothed wheel 19 provided with a toothed sector 33 of large pitch co-operating with a spring-urged pawl 32, the wheel 19 meshing with a pinion 31 on the spindle of which is mounted a ratchet wheel 29 cooperating with a spring-influenced pawl 28. The milling-cutter 3 is mounted on a rocking arm 7a integral with an adjustable arm 7b which bears on a cam-operated oscillatable lever 12, the latter carrying at its free end a rod 18 which when it bears on an arc-shaped boss 20 on the wheel 19 causes the milling-cutter to be kept away from the blade wires and a number of quick long feed steps to be given to the feed rollers 35, 36, by means of the pawl 32 and toothed sector 33, and when it bears on the face of the wheel 19 causes the milling-cutter 3 to be lowered into the blade wires and a number of short slow feed steps to be given to the rollers 35, 36 by means of the pawl 28 and ratchet wheel 29. The blade wires are each unwound from a drum to pass to the feed rollers 35, 36, and after leaving the guide 24 are each wound on to another drum. The edges of the feed rollers 35, 36 are staggered with respect to the edges of two protective plates. The feed roller 36 is mounted on a slide which is adjustable towards and away from the roller 35. The guides 23, 24, each comprise a base-plate, adjustable side-plates, and an upper locking- plate, the side-plates of the guide 24 being unhardened to permit of penetration thereof by the milling-cutter.

Patent GB-697007-A (GB)
Title: Improvements relating to the recovery of unsaponifiables from concentrates containing unsaponifiables admixed with saponified fatty materials
IPC: F25J3/04
Filed: 1950-05-04
Abstract: A process for recovering sterols, e.g. cholesterol, from a sterol concentrate having a major proportion of soap in admixture therewith, e.g. saponified still bottoms, comprises extracting the concentrate with a liquid sterol solvent comprising an ester, containing not more than 8 carbon atoms, of a lower fatty acid and a lower monohydric alcohol, e.g. ethyl acelate, separating a solvent extract having sterols dissolved therein, and recovering sterols from this extract. The extraction may be effected under anhydrous conditions and by counter-current flow.  As an additional step oxalic acid may be added to the solvent extract, thereby forming an insoluble addition complex of sterols and oxalic acid, separating the complex from the reaction mass and decomposing it to recover the sterols.  Preferably prior to the addition of the anhydrous oxalic acid the amount of solvent in the solvent extract is adjusted until the sterols in the extract amount to between 20 and 40 per cent thereof.

A substance to be melted or the fluidity thereof increased is heated in a container by an electrical heating film which is mounted so as to progress with or through the substance as the change occurs. The heating film, which incorporates at least one conductive meander pattern consisting of substantially parallel conductive arms with narrow elongated insulating spaces between the arms and bridges joining the ends of the arms, is preferably as described in the parent Specificatiou, and may incorporate features described in Specifications 1,020,312 and 1,020,316. The apparatus shown is for melting solid material, e.g. paraffin wax or phenol, in a drum which may be dispensible. The heating film 86 is attached to a partspherical disc 87 of lower specific weight than the wax or phenol and therefore rises on a guide 88 as melting proceeds and may actuate a signal or cut-off switch when it reaches the top of the drum. In an alternative form of apparatus (Fig. 2, not shown), for vaporizing a solid or liquid, a perforated film is spaced below a float which descends as the vaporization occurs until it reaches the bottom of the container where it may actuate a switch.

Title: Method of producing titanium concentrates by reduction smelting of titanium-bearing iron ores
IPC: C22B34/12
Filed: 1956-04-17
Abstract: Titanium concentrates are produced from ferro-titanium ores by a reduction smelting process using pulverulent iron and carbonaceous material as reducing agents (see Group II).  The slag, which in an example contains 73 per cent of TiO2, is separated from the pig iron melt and is treated with hot solution of sulphuric acid containing 10 per cent of H2SO4, washed with water and kiln dried to give a product containing a higher proportion of TiO2, in the example 95.4 per cent. Sodium carbonate may be added as a flux during the smelting process, in such proportions that a compound 3TiO2.Na2O, having a melting point of 1128 DEG  C., is formed.ALSO:Titanium concentrates are produced from ferro-titanium ores by a reduction smelting process using pulverulent iron and carbonaceous material as the reducing agents so as to ensure that reduction of ferric to ferrous oxide, reduction of ferrous oxide to iron and carbonization of the iron to give a pig iron melt take place successively and selectively in accordance with the increase in temperature.  Reduction of ferric oxide takes place in the range 900-1000 DEG C, reduction of ferrous oxide in the range 1100-1150 DEG C. and carbonization of the iron and production of a pig iron melt in the range 1150-1200 DEG C.  A flux may be added to produce a fluid slag.  Thus sodium carbonate may be used in amount sufficient to produe a compound of the formula 3TiO2.Na2O having a melting point of 1128 DEG C.  The reducing agent may be added as required for each stage of the operation the flux being added just before the second reduction or with the batch of carbonacous material required for carbonization of the iron.
