Patent GB-377239-A (GB)
Title: An improved process for producing diamonds
IPC: B01J3/06
Filed: 1931-01-21
Abstract: <PICT:0377239/III/1> Diamonds are produced artificially from melts capable of yielding carbon in a free condition by subjecting the melt to increases and decreases of pressure, the decreases in pressure being made more rapidly than the increases.  Amorphous carbon, e.g. graphite, is added to the melt, which may be of iron, nickel, cobalt, silver or silicates, together with a carbon compound, e.g. solid carbon dioxide or liquid carbon monoxide, also supplied during the operation.  The final temperature attained is about 1000 DEG  C. and the pressure may vary from 500 atmospheres to a final pressure of 15000 atmospheres.  The melt is preferably composed of materials which act catalytically and easily dissolve the carbon compounds, e.g. iron, nickel, cobalt and their oxides.  In an example, a melt consisting of 60 to 90 per cent of iron filings, 25 to 5 of blast furnace slag, and 15 to 5 of amorphous carbon is placed in a chamber 5 in a steel block 1 together with 30 per cent of solid carbon dioxide.  Secured to the upper block 1 by insulated bolts 8 and separated therefrom by an insulating layer 4 is a lower steel block 2, a tubular passage 10 for carbon monoxide or dioxide being provided therein.  Pressure is furnished by a hydraulic ram 3 provided with packing 9 and also by the gas supplied.  Heating is effected by the resistance of the blocks 1, 2 to current supplied by leads 6, 7.  In operation, the melt is liquefied by heating to about 1000 DEG  C. and a pressure of 5000 atmospheres is applied, some of the carbon and the carbon dioxide dissolved giving rise to the production of carbon monoxide. Pressure is now increased to 15000 atmospheres over a period of 90 seconds during which time carbon monoxide is converted to carbon and dioxide.  After a further period of 10 to 20 seconds, the heating and pressure are simultaneously interrupted, the sudden release of pressure which is effected serving to prevent carbon in the diamond form reverting to the amorphous form.  This procedure is repeated three or four times.

Patent GB-269691-A (GB)
Title: Improvements in or relating to apparatus for recording speed or motion
IPC: G01D15/00
Filed: 1926-01-27
Abstract: 269,691. Bruhn, F. W. G. Jan. 27, 1926. Temporary recorders.-In order that the necessity for changing the record chart of a speed-indicator &c. periodically mav be avoided, the marking point is arranged to mark a sheet or dial from which the record is subsequently effaced automatically. The recording device is of the type in which a disc c, Fig. 3, is backed by a disc d of iron foil or other material. The disc d is dark in colour and coated with a sticky substance, so that a record is made when the discs c, d, are pressed together by a marking point f. The point f is carried by a rack bar f<1>, Fig. 1, which is positioned by a pinion g on the spindle of the speed indicating hand. The previously made record is effaced automatically just before reaching the marking point by separating the discs c, d. In the arrangement shown in Fig. 3 this separation is effected by magnets h<1> which draw the iron foil d away from the disc c. The discs may be separated by a bar passing between them, or by making the foil disc d slightly longer than the other, and causing a fixed projection to make a loop in it just in front of the marking point. The marking pin may be of the kind which produces an oxidizing line on a sheet, in which case the record is effaced by a chemically treated pad. Figs. 5 and b show an arrangement in which the marking point is brought into contact with the foil by the jolting of the vehicle to produce an " in-motion " instead of a speed record. The effacing magnet h, which carries the marking point f on one of its arms, is mounted on a pivot p and acted upon by a spring r so that the jolting of the vehicle will bring the marking point against the record foils. In this arrangement a number of concentric record foils are provided corresponding for instance to different days of the week. The marker is moved from one circle to another by a stepped clock-driven cam l which acts upon a slide n to which the magnet h is pivoted. The record may be in the form of a spiral instead of a number of concentric circles. Fig. 7 illustrates means for maintaining the rotation of the recording chart in the event of the vehicle drive breaking down. The normal drive is by means of gears t - - w and the auxiliary drive comprises a weighted lever z which is pivoted at y and is adapted, when jolted by the movement of the vehicle, to drive the gear v through a pawl and ratchet 22. A clutch 23 is provided and the arrangement is such that the normal drive from the gear t is faster than that from the lever z. The lever z may be held stationary while the speedometer hand s is in movement by a pivoted latch 24 which is set by pins 26 on a gear 25<1> engaged by a gear 25 on the spindle of the speedometer hand. In place of the lever z, a spring motor may be arranged to actuate the auxiliary drive.

Title: Process of producing and refining organ extracts
IPC: A61K31/00
Filed: 1936-01-25
Abstract: An anti-anaemic substance is separated in concentrated form from extracts of liver, spleen or other organs by lixiviation with phenol cresol or other phenolic solvents which have been liquefied, if necessary, by heating or by addition of a liquefying agent such as a small percentage of water.  In a modification the active substance is adsorbed from the extract by means of active carbon, silica gel, fuller's earth or the like and the adsorbate is lixiviated with a phenolic substance.  The active substance is recovered from the phenol by precipitation with a relatively large volume of a water miscible liquid such as alcohol or acetone, or a liquid, such as ether or chloroform, which is miscible with the phenol but not with water may be added and the active substance thereupon extracted with water.  The lixiviation with phenol is preferably carried out at pH 6,5 to 8, but may be conducted fractionally by starting at a strongly acid reaction and neutralizing in successive steps, or by addition of a blocking agent, such as formaldehyde, and gradually eliminating this by addition of suitable reagents.  An aqueous extract from which only ballast substance have been removed by fractional lixiviation with phenol may be further treated by known methods.  The initial extract may have previously been treated to remove proteins, as by precipitation with alcohol.  When a dry extract is treated the phenolic solution obtained is preferably washed with water whereby certain dissolved ballast substances are removed.  In the case of an adsorbate this may be prepared in presence of a dilute solution of a phenol or may be washed with such a solution prior to lixiviation with concentrated phenol.  In a further modification an aqueous liver extract is acidified, treated with excess of warm acidic phosphotungstic acid, or an equivalent such as phosphomolybdenic acid or arsenomolybdenic acid, and cooled; the precipitate formed is separated, dissolved by addition of alkali to adjust the pH to 7 to 8 and the solution lixiviated with phenol.
