Title: Production of germicidal compositions
Inventor: BROWN JOSEPH PATRICK
IPC: A01N31/08
Filed: 1955-10-26
Abstract: Residues from the manufacture of phenol are washed in liquid form with water, the washed residues are distilled, and the distillate of higher boiling point than phenol is chlorinated to give a product stated to have germicidal activity.  The residues used in this process are those remaining in the still after the distillation of phenol from the mixture obtained by fusing neutralized benzene sulphonic acid with alkali, e.g. caustic soda, quenching the hot material with water, acidifying the mixture and separating and drying the phenol layer.  The washing in liquid form with water is advantageously effected by washing the residues with water maintained at above 90 DEG  C., preferably at a pH of from 6 to 8, this being adjusted by addition of, for example, caustic soda or hydrochloric or sulphuric acid.  A suitable distillate for the chlorination stage is stated to be one having a boiling point of 160 DEG  to 200 DEG  C. at 16 mm.  The chlorination may be effected with any suitable chlorinating agent, advantageously sulphuryl chloride or gaseous chlorine, and preferably sufficient chlorinating agent is used to introduce 1 part by weight of chlorine into about 5 parts by weight of distillate.  In examples: (1) molten phenol residues as defined are stirred at 95 DEG  C. with water at a pH of 8, the lower layer obtained on settling is rewashed, the lower layer is again separated and then distilled at 16 mm., the fraction boiling at 160 DEG  to 200 DEG  C. is chlorinated with sulphuryl chloride at 80 DEG  C., the chlorination product is blown with air at 100 DEG  C. and strip-distilled at 16 mm. and the product is again blown with air at 100 DEG  C. to give a red oil of boiling point 150 DEG  to 220 DEG C. at 15 mm.: (2) the chlorination is effected with chlorine gas at 80 DEG  C. and the chlorinated product is air-blown at 90 DEG  C. and strip-distilled, giving a product of boiling range as in (1).

Abstract: 1483693 Adjusting drum brakes for wear DBA SA 23 July 1975 [17 Sept 1974] 30826/75 Heading F2E In a drum brake having a wear adjusting lever 26 and pawl 32 pivoted to a common shoe 12, the lever tending to follow the movement of the other shoe under the action of a spacer and spring assembly 40, 46 extending between lever and shoe, operation of the wear adjusting mechanism is prevented when the brake temperature exceeds a predetermined value. As shown in Fig. 1, an auxiliary lever 48 which normally abuts the pivot 34 of the pawl is moved by a bimetallic element 50 so that its teeth 58 engage those of lever 30 to prevent rotation of the latter. In the embodiment of Fig. 2 rotation of the pawl is prevented when the bimetallic element 150 moves auxiliary lever 148 sufficiently far to register an abutment surface 160 on the lever with a complementary surface 164 on the pawl. Alternatively, the bimetallic element 250 (Fig. 5) may be mounted on the opposite side of the shoe 212 to pawl 232 and carry a projection 266 which can extend through an aperture 268 in the shoe to prevent pawl rotation.

Abstract: 1342952 Film frame position detection GTE SYLVANIA Inc 1 July 1971 [16 July 1970] 30966/71 Heading H4F [Also in Division G2] In a continuously moving photographic film flying spot scanning system of the type described in Specification 1,342,951, the position of film frames relative to the scanning zone is sensed by means of an electromechanical transducer 31 arranged adjacent the film 33 and which in response to the sprocket holes 35 in the film generates electrical signals which are used to modify the vertical scanning signal fed to the flying spot scanner's CRT. The transducer may comprise a piezoelectric or electromagnetic device, which produces an electrical signal having a leading and a trailing edge due to the ingress and egress of its stylus from a sprocket hole. As shown the transducer comprises a stereoscopic gramophone pickup device (although a monaural pickup may be used) having a stylus 37 and left and right piezoelectric devices 39 and 41 which are series connected. Reversal of film movement requires reversal in selection of the leading and trailing edges of the electrical signal.

Patent GB-603762-A (GB)
Title: Improvements in or relating to the manufacture of porous metal
IPC: B22F3/11
Filed: 1945-11-21
Abstract: In a process for the manufacture of a porous metal article, a porous mass of a metal which sinters relatively easily is coated with another metal which sinters less easily, under conditions such that the porosity of the mass is not destroyed.  Copper and its alloys may be used as the easily sintered metal and chromium, silver, cobalt, nickel and their alloys for the coating.  A porous metal mould for casting lead, in particular for battery grids, is made by sintering copper, brass or bronze powder and then electrolytically coating the mould with chromium so as to prevent adhesion of the lead to the mould.  By first plating in the ordinary way and then reversing the current, a porous coating is obtained which will not hinder the venting of trapped air through the walls of the mould.  The invention may also be applied to the making of a self-lubricating valve guide, a thin layer of a wear-resistant material such as chromium being applied to the bore and top faces of the sintered porous guide.

Patent GB-316872-A (GB)
Abstract: 316,872. Scheiber, J. Aug. 4, 1928, [Convention date]. Fats and fatty oils; fatty acids.-The properties of wood oil are imparted to drying oils having a plurality of double bonds such as linseed, perilla, poppy-seed, soya bean, sunflower, hemp seed, nut, corn and fish oils such as Menhaden oil by addition of substances such as halogens, hydrochloric acid, hypochlorous acid and sulphuric acid and its derivatives such as alkyl sulphuric acid, to at least one of the double bonds and subsequent decomposition of the addition products. The oils can be used directly or emulsified with water, preferably with the addition of suitable agents such as Turkey Red oil, bisulphite solutions and alkyl substituted naphthalene sulphonic acids with or without the simultaneous use of solvents such as pyridine. Temperatures above and below normal, and increased pressure may be used in effecting the addition, and the subsequent splitting off of the addition products themselves or of their hydrogen compounds is partly carried out by the addition of suitable substances e.g. alkalies, partly by the isolation of the addition compounds and by heating at ordinary or reduced pressure. In examples (1) Linseed oil is treated with chlorine and then with a metal such as zinc to split off hydrochloric acid. (2) Sodium hypochlorite solution is added to Soya bean oil emulsified with water. Mineral acid is added to separate the oil, which is treated at 200-220‹ C. to split off water and hydrochloric acid. It is stated that conjugated double bond systems are formed from the systems originally containing isolated double bonds. The products may be used in place of wood oil in paints, varnishes, printing compositions and printing inks, which may also contain fillers pigments, cellulose esters and india-rubber or depolymerization products of india-rubber. Specifications 9027/11, [Class 95, Paints &c.] and 18818/11 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of partially or completely saponified oils, or mixtures of their fatty acids. The addition of hydroxyl groups by oxidizing agents, such as hydrogen peroxide and permanganate, or by " blowing," and the use of catalysts in the addition and decomposition reactions are also described. This subject-matter does not appear in the Specification as accepted.
