Filed: 1938-10-17
Abstract: 513,938. Two-part couplings. COOPER, C. A. Oct. 17, 1938, No. 28153/37. [Class 38 (i)] An electrode holder for electro-medical apparatus comprises a tubular socket 2 adapted to receive the electrode 3 and to guide it into engagement with the resilient contact member 4 mounted in the socket and adapted to bear against the end of the electrode and a resilient ring 6 fixed to the socket and projecting inwardly of the walls thereof so as to grip the electrode firmly by friction, the construction being such that the electrode is held in axial alignment with the contact member by the walls of the socket and is held firmly against the contact member by the frictional grip of the resilient ring acting against the endwise pressure of the contact member. The casing 1 serves as a handle and may contain an induction coil for generating high frequency current. The resilient ring 6 which may be of rubber and mounted in a groove 7 in the wall of the socket may coincide with a groove or notch in the electrode to form an elastic locking device. The socket which may have tapering walls may be of non-circular cross-section in the region of the spring contact and the end of the electrode may be of similar cross-section thereby preventing rotation of the electrode.

Title: An improved method of and apparatus for controlling continuous vacuum rectification of coal tar phenols and other mixtures of homologous compounds
IPC: C07C37/74
Filed: 1945-10-25
Abstract: <PICT:0619857/III/1> The composition of the top fraction in the vacuum rectification of mixtures of close-boiling, homologous compounds liable to be decomposed by heat, such as coal tar phenols, is controlled by keeping substantially invariable proportions between the rate of supply of feed (assumed to be of constant composition), the rate of reflux return, and the rate of discharge, from the system, of the condensate of the top fraction.  The control is achieved by employing, in addition to the usual column with an adjustable boiler, an adjustable feed-pump, and by inserting flow-meters in the reflux and discharge conduits.  The flow-meters may be used, with the aid of relays, to make the regulation automatic.  In the rectification of coal tar phenols, three columns 1, 13 and 14 maintained at a pressure of about 20 mm. by device 33, are employed.  The phenols are freed from water, pyridine bases and neutral oils in auxiliary column 18 and then fed, by pump 2, from tank 22 into column 1 via pre-heater 29.  The various adjustments are made so that the vapours of phenol itself (of at least 90 per cent purity) pass out of the top of the column.  These vapours are in part condensed in analyser 4, the remainder being condensed in cooler 31. The condensate from the analyzer is returned to the column as reflux through conduit 5 which is provided with flow-meter 6.  The condensate from the cooler is removed from the system through conduit 11 which is provided with flow-meter 12. The proportions refluxed and discharged are regulated by means of analyzer 4, and the reflux ratio is maintained at the required value, e.g. the minimum necessary to maintain the purity of the top fraction, by adjusting the temperature of boiler 30.  The residue leaving boiler 30 is fed by pump 34 into column 13, which has the same equipment as column 1, and from the top of which vapours of ortho-cresol are withdrawn.  The residue leaving boiler 38 is fed by pump 45 into column 14 from the head of which meta-para-cresol is withdrawn.  The feed pumps 2, 34, 45 are driven by the same transmission, the discharge of each being regulated as a function of the composition of the feed mixture. The invention may also be carried out using total condensers and reflux pumps in place of the analyzers.  Specifications 224,085, [Class 32], and 619,856 are referred to.

Filed: 1926-11-11
Abstract: 285,152. Botson, R. Nov. 11, 1926. Treatment preliminary to tanning. - A depilatory material for use in removing hair from hides and skins or from human skin is obtained by treating an alkali sulphide, e.g. sodium sulphide with dry steam under pressure until it passes into solution. The solution is stated to have properties different from those of a solution obtained by dissolving an alkali metal sulphide in water. A proportion of terpinolene is added to the solution for the purpose of facilitating the precipitation of impurities and after standing the solution is filtered and an equal quantity of caustic soda solution of the same specific gravity is added. The solution is again filtered and the filtrate concentrated and cooled to cause the crystallization of the desired depilatory substance. The crystals so obtained are dissolved to form baths of various strengths to which lime or barium or strontium oxides or hydrates may be added.

Title: Process for the production of bituminous emulsions
IPC: C08K5/098
Filed: 1937-10-20
Abstract: The sensitivity towards lime of bituminous emulsions made with neutralized fatty acid soaps or other soluble emulsifying agents such as the alkali salts of sulphonated naphthenic acid, but which are free from fillers or solid dispersing agents, is lessened by the addition of about 0,6-1 per cent (calculated on the weight of emulsion) of alkali salts of dicarboxylic acids having 2-5 carbon atoms.  Suitable acids are oxalic, malonic or succinic acids, and the salts may be added during or after the production of the emulsion. According to an example, 3 kgm. of fatty acid and 6 kgm. oxalic acid are neutralized with caustic potash solution until an alkaline reaction is obtained, and the whole diluted to 40 litres.  This solution is heated to 80 DEG  C. and emulsified with 600 kgm. of bitumen previously heated to 100 DEG  C. The emulsion is insensitive to lime and may be diluted with hard water without precipitation. Specification 362,299 is referred to.

Abstract: 280,204. Jellinek, P., and Beer, F. Nov. 2, 1926, [Convention date]. Logarithmic calculators; surface areas, computing; cubical contents, measuring.-An instrument for effecting multiplication and division and particularly applicable for determining areas and cubical contents from direct linear measurements, comprises a cylinder 5 rotated by the running-out of the measuring tape 2 and adapted to produce a movement of the indicator proportional to the sum of the logarithms of the measurements. The tape 2 is wound on a drum 1 coupled to the cylinder 5 provided with a guide rail or groove 6 having the equation y=k log. x. Engaging the groove is a pin 7 carried by a block 8 guided for vertical displacement only and connected by a cord 10 with a spring drum 12 toothed at 14 to be engaged by a pawl 16 mounted on a coaxial drum 17. Both drums are restrained by internal spiral springs and reversal of the drum 17 is normally prevented by a pawl 20 arranged on the casing 4. Secured to the drum 17 is a graduated disc 18 read against a stationary pointer. To multiply successively the tape is drawn out proportionally to each of the various values and at each release the cylinder 5 and drum 12 together with the block 8 return to their initial positions while the disc 18 shows the logarithmic sum of the values. To zeroize this disc the two pawls 16, 20 are disengaged to allow the disc 18 and drum 17 to return under the spring action. The pawl 20 s disengaged by depression of a button 24, Fig. 5, and pawl 16 is disabled by a handle 26 engaged by a spring plunger 29 to retain the pawl out of engagement until allowed to re-engage by manipulation of the plunger extension 32. Topermit of division a reversing gear may be interposed between drum 17 and disc 18 and to ensure greater accuracy the pawl 20 may engage with several circles of teeth mutually staggered. The coupling between the drum 1 and the cylindermay permit lost motion equivalent to the withdrawal of unit length of the tape and also to the distance lost between the drum and the corner of the article to be measured. Alternatively this distance may be allowed for by the provision on the tape of marks in the form of handles. According to the Specification as open to inspection under Sect. 91 (8) (a) a device may be incorporated whereby the drum 17 is locked' immediately the cvlinder commences to return. This subject-matter does not appear in the Specification as accepted.
