Title: Regenerated cellulose fibres and their production
IPC: D01F2/06
Filed: 1961-02-28
Abstract: Regenerated cellulose yarn is produced by spinning viscose having a xanthate ratio of at least 50 into a primary sulphuric acid coagulation bath and then through three successive sulphuric acid coagulation baths, the strength of the second bath being not more than half that of the first bath and the strength of the third and fourth baths being not less than that of the preceding one, the conditions being such that the xanthate ratio after the second bath is 20-40, substantially no stretching is effected in the first and second baths, and stretching to more than twice the original length is effected in the third and fourth baths.  Each bath contains sodium sulphate and zinc sulphate in addition to sulphuric acid.  The second and third baths may be replaced by a single bath provided with a suitably placed godet roller for returning the yarn to the bath. Using a viscose solution having a viscosity of less than 150 poises and containing 3-11% cellulose and 3-13% total alkali, the acid bath strengths may be successively 40-180, 5-30, 10-50 and 30-100 gm./1 of sulphuric acid.  If the initial xanthate ratio is 65-75, the primary bath strength is 70-100 gm./1, and the xanthate ratio after the second bath is 30-40; more than 30 permanent crimps per inch may be subsequently produced by conventional means, even with filaments having a denier number of more than 10.  Using a viscose solution having a viscosity of more than 150 poises and containing 3-11% cellulose and 3-13% total alkali, the acid bath strengths may be successively less than 60, less than 30, less than 30, and 30-100 gm./1.  The viscose solution may contain 0,1-1,0 millimoles of a coagulation modifier per 100 gm. of viscose.  Various amines, N-substituted dithiocarbamates, mercaptoamines, N-substituted mercaptodithiocarbamates, glycol mercaptans, and alkoxy-alkanols are specified as coagulation modifiers.  Examples specifying coagulant composition and temperature and degree of stretch are given.ALSO:The compressive resilience and crimp recovery from stretch of regenerated cellulose fibres (see Group IV(a)) and articles made therefrom are improved by treating with an aqueous solution of 0.5-4% of an oxy-acid salt of melamine, exposing to formaldehyde vapour in the presence of 10-30% of water and heating at 120 DEG -160 DEG C. until the resulting resin has set.  The oxy-acid may be lactic, glycollic, thioglycollic, or gluconic acid.  The salt may contain 0.3-3.0 moles of oxy-acid per mole of melamine and 2-5 moles of formaldehyde may be employed per mole of melamine.

Title: New phenolic antimicrobial compositions
IPC: A01N31/16
Filed: 1964-02-21
Abstract: Halogen substituted o-hydroxy diphenyl ethers, (o-phenoxy phenols) of the general formula <FORM:1022744/C2/1> wherein X, Y and Z may each be Cl or Br, and one of Y and Z may be hydrogen, are prepared by two different processes: (A) the corresponding o-aminodiphenyl ether is converted to a diazonium salt, which is then hydrolysed; (B) the corresponding o-methoxy compound is demethylated.  In accordance with A, an example is given wherein 2-amino-4,41-dichlorodiphenyl ether is first reached with nitrosyl sulphuric acid in C.H2SO4, and then hydrolysed with water in the presence of o-dichlorobenzene, to 2-hydroxy-4,41-dichlorodiphenyl ether.  Other analogous ethers are prepared in like manner.  Procedure (B) is exemplified by reaction of 4-chloro-2-methoxy phenol with 3,4-dichloro-1-nitrobenzene to give 2 - methoxy - 4,21 - dichloro - 41 - nitro - diphenyl ether, which is catalytically reduced, (H2 and Ni) to the corresponding 2-methoxy-4,21-dichloro-4-amino diphenyl ether.  This is then diazotized and reacted with either freshly made cuprous chloride in c.HCl to replace the amino group with halogen, giving 2-methoxy-4,21,41-trichlorodiphenyl ether, or with copper powder in boiling ethanol, to replace the amino group with hydrogen giving 2-methoxy-4,21-dichlorodiphenyl ether.  The methoxy group is then hydrolysed off by reaction with aluminium chloride in boiling benzene, or heating with aqueous or acetic hydrobromic acid to give the corresponding o-phenoxy phenol. Other ethers are prepared in like manner.  The compounds are used for internal and external antimicrobial compositions (see Divisions A5).ALSO:Antimicrobial compositions, for internal and external use, comprise at least one halogenated o-hydroxydiphenyl ether, of general formula: <FORM:1022744/A5-A6/1> wherein X, Y, and Z are each Cl or Br, and one only of Y and Z may be hydrogen, together with an appropriate carrier, and, optionally other known antimicrobial agents.  Forms stated for the compositions are ointments, powders, tinctures, gargles, and mouthwashes (or tablets therefor) for external use, and tablets or dragees for internal use, for disinfecting the urinal and p  intestinal tract, conventional excipients being used in all cases. Other active ingredients named are sulphur, for use in powders, and zinc stearate for ointments.

Filed: 1974-02-19
Abstract: 1466877 Speed governor ROBERT BOSCH GmbH 19 Feb 1974 [20 Feb 1973] 7378/74 Heading G3B A centrifugal speed governor for an I.C. engine comprises a tipping lever 30 hinged at 29 to an arm 28 of a regulating sleeve 16 and located between a pair of spring-urged stops 43a, 44a, and a shift lever 32 one end of which is connected to the tipping lever 30 and the other end to an intermediate lever 33, characterized in that the stops are spring- urged on to opposite faces 41, 42 of the tipping lever, one of the springs 45 being located in the sleeve 16 and the other in an adjustable screw sleeve 55 in a power transmissive lever 20. An idling regulator spring 50 is also located in the sleeve 55. In operation, the fuel quantity adjusting member 35 is moved manually in direction V by an operating lever 38, to produce a large supply of fuel for starting. As the speed increases the sleeve takes up the distance between a shoulder 52 of a sleeve 51 inside the sleeve 55, and the end of sleeve 55 by moving the tipping lever 30 the distance b. This rotates the shift lever 32 anti-clockwise tending to cause the member 35 to move in the direction S to reduce the supply of fuel. After the initial stress of the spring 45 is overcome, it allows movement a during which the pivot 29 of the tipping lever 30, which is carried by the sleeve 16, rocks that lever clockwise and so moves the member 35 in the direction V to increase the fuel supply. Then, after the initial stress of the spring 49 is overcome, it allows a movement c, during which the tipping lever 30 is rocked counter-clockwise and the member 35 moved back in direction S. Thereafter the sleeve 16 acts against the main spring 27 to regulate the final speed. The spring 49 may have a greater spring rate than spring 45 giving different regulating characteristics, Fig. 3 (not shown).
