Abstract: 397,050. Coke ovens. STILL, C., Recklinghausen, Westphalia, Germany. March 13, 1933, No. 7546. Convention date, March 23, 1932. [Class 55 (i).] Distillates are withdrawn from a coke oven through ducts 17 disposed in the interior of the charge, and extending at the top into a gas collecting space 5, the width of which is considerably less than that of the oven chamber 2. Each space 5 is screened from the heating flues 4 by insulating spaces through which air may pass, or by insulating layers 20, so that the distillates may not be overheated before passing to the outlet main 8.

Convention date, March 23, 1934. [Class 40 (ii)] [See also Group XX] In order to reduce the clear parts of records for " noiseless " reproduction and to avoid the cutting of steep wave - fronts, the " antiground - noise blackening " is systematically advanced by several millimetres relative to the corresponding sound record. Part of the sound currents from the amplifier 21 influences the oscillograph recorder 22, 27 to produce the sound record 10, and part is amplified at 38 and rectified at 41 to produce a current varying with the intensity of the sound, this current influencing the recorder 29, 34 to produce the auxiliary " blackening " 12, the origin of which is displaced as at 35 relative to the origin 36 of the sound record. A photographic reversal step may be used in the development of the master film or of each copy. The Specification as open to inspection under Sect. 91 states that a similar process may be used for re-recording, the auxiliary recorder being controlled by an auxiliary " reading-device " arranged in advance of the main one. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 374,996 and 406,635.

Title: Process for Separating Solids of Different Specific Gravities.
Inventor: MELLERSH-JACKSON WILLIAM JOHN
IPC: B03D1/08
Filed: 1917-05-29
Abstract: 111,638. Jackson, W. J. Mellersh-, (Virginia Haloid Co)May 29, 1917. Wet-separating.-Solids of different specific gravities, e.g. ores and gangue, are separated in a liquid of intermediate specific gravity and the separated solids are treated for the recovery of the separating-liquid by washing with a relatively large volume of a liquid which has a boiling- point below that of the separating-liquid and is a solvent of the separating-liquid at substantially below its own boiling-point and preferably also at ordinary temperatures, the washing being effected at a temperature above the melting-point of the separating-liquid and below the boiling- point of the solvent. The separating-liquid may be tin bromide or arsemous bromide, and the solvent may be carbon bisulphide; and in some cases there may be used a separating-liquid obtained by the addition of some of the solvent tn the bromide &c. The washed solids are heated to remove the solvent which is recovered for reuse. and the solution of separating-liquid is heated to remove all or the required amount of the solvent. In the apparatus shown, the separated solids are moved in opposite directions through the liquid in the separating vessel a, Fig. 3, by a conveyer d, and are discharged to devices m for the recovery of the separating- liquid. Each of these comprises communicating inclined cylinders i, j, k, l, Fig. 1, containing screw conveyers and having solvent inlets n and solution outlets o, the solid passing from the last cylinder l through a eteam-jacketed drying-cylinder r. The solution is collected in an evaporator p from which the evaporated solvent and the vapour from the drying-cylinder r are returned to a condenser s.

Patent GB-589747-A (GB)
Title: Improvements in or relating to liquid lubricants
IPC: G04B31/08
Filed: 1945-03-28
Abstract: Synthetic lubricating liquids for use with fine mechanisms such as watches, clocks and other measuring instruments comprise a mixture of two or more liquid non-fatty organic esters, having a high boiling point and low setting point.  One or more of the esters may be of aromatic acids, e.g., phthalic acid; aliphatic acids, e.g., acetic acid; or hydroxy acids, e.g., glycollic acid. The esters may be of mono-, di-, or polyhydroxy alcohols, or of more than one such alcohol.  There may be included in the lubricant a proportion of up to about 10 per cent. by weight of an ester of a cyclic alcohol and a higher fatty acid, e.g., methyl cyclohexanol stearate in order to impart increased "oiliness" at elevated temperatures such as 100 DEG F.  There may also be incorporated in the lubricant a minor proportion of an anti-oxidant such as alpha-naphthol or any of the other usual antioxidants.  The lubricating liquids to be used have a minimum boiling point of the order of 200 DEG C. at an absolute pressure of 20 mm. of mercury, a maximum rate of evaporation of 0.0002 grm/sq. cm./hour at 100 DEG C., and a setting point not in excess of minus 30 DEG C.  An example of a lubricating fluid for mechanisms such as larger clocks consists of butyl phthalyl butyl glycollate 60 per cent., methyl phthalyl ethyl glycollate 20 per cent., methylcyclohexanol stearate 5 per cent., dibutyl phthalate 10 per cent., triacetin 5 per cent., and alphanaphthol 0.1 per cent., all proportions by weight.  The function of the glycollates is to impart non-spreading properties, the relative proportions of the butyl and methyl glycollates being adjusted to give the required viscosity; the dibutyl phthalate moderates the non-wetting properties of the glycollates, and the triacetin, being slightly hydrolysed by water vapour, serves to neutralise any moist alkaline industrial atmospheres to which the instrument might be exposed and which would tend to soften any shellac jewel mounts used in its construction.
