Title: Production of oil-soluble salts of sulfopolycarboxylic acid esters of alkylene oxide adducts
Inventor: LINDNER PAUL LINDENWAYS
IPC: A01N25/30
Filed: 1966-10-05
Abstract: Novel oil-soluble salts of sulphopolycaroxylic acid esters of oxyalkylene adducts of compounds having at least one hydrophobic straight or branched chain alkyl or acyl radical of 8 to 24 carbon atoms and having at least one hydroxy or mercapto radical wherein at least one of the carboxyl groups is neutralized by an aliphatic amine of 2 to 8 carbon atoms are prepared by reacting the oxyalkylene adduct of the hydrophobic radical-containing hydroxy or mercapto compound with the sulphopoly carboxylic acid.  The adducts contain 1 to 15, especially 1 to 10, ethenoxy groups, 1 to 12 propenoxy groups or 1 to 5 butenoxy groups, or mixtures thereof, and are preferably adducts of aliphatic alcohols of 8 to 18 carbon atoms or of fatty acid partial esters of aliphatic polyhydric alcohols having 8 to 18 carbon atoms.  The sulphopolycarboxylic acid contains 7 to 8 carbon atoms and is preferably dicarboxylic in nature, e.g. sulphosuccinic acid, and both the sulphonic group and the free carboxyl group may be neutralized by the amine.  Especially preferred compounds are those of Formula I <FORM:1108410/C2/1> wherein R and R1 are each alkyl radicals of 8 to n carbon atoms, n is 0 or 1, w is 3 to 10, and M and M1 are alkali metal cations or cations of aliphatic amines of 2 to 8 carbon atoms, e.g. isopropylamine, isopropylamino ethanol, isopropyl aminodiethanol or sodium.  When the acid is sulphosuccinic acid, the corresponding compounds may be prepared by reacting a maleic acid ester of the alkylene oxide adduct with a solution containing an aliphatic amine, sufficient water to provide a reaction medium, containing dissolved sulphur dioxide to form a sulphite of the amine, and a water-miscible alcohol.  The compounds of the invention may be used as wetting agents emulsifiers and dispersants in the soap and textile industry and in agriculture.ALSO:Dispersant compositions for biocidal toxicant concentrates comprise novel oil-soluble salts of sulphopolycarboxylic acid esters of alkylene oxide adducts of compounds having at least one hydrophobic straight or branched chain alkyl or acyl radical containing 8 to 24 carbon atoms and at least one hydroxyl or mercapto radical, wherein the sulphopolycarboxylic acid used in forming the ester contains 4 to 8 carbon atoms, and at least one of the carboxyl groups of the ester is neutralized with an aliphatic amine of 2 to 8 carbon atoms in combination with e.g. chlorinated insecticides such as benzene hexachloride, aldrin, toxaphene, chlordane, heptachlor or dieldrin and water-soluble fertilizers such as diammonium phosphate or ammonium nitrate and urea the whole being mixed to form a stable emulsion or dispersion. Examples of the oil-soluble salts according to the invention include the isopropylamine di-salt of nonyl phenol tetra-ethenoxy sulphosuccinate and the isopropylamine di-salt of lauryl alcohol tetraethenoxy sulphosuccinate.

Abstract: 1,146,270. Sorting by gauging. OWENS-ILLINOIS Inc. Feb. 25, 1966, No. 44557/68. Divided out of 1,143,211. Heading G1M. In an apparatus for sorting bottles by size and shape the bottles are fed one by one to a first sorting station where a first dimensional characteristic of the bottles is determined and bottles conforming to the characteristic are fed away in one direction while the remaining bottles are grasped by a suction device and moved in a circular path to a second sorting station where a second dimensional characteristic is determined and bottles conforming thereto are released by the suction device and led away on a conveyer while the remaining bottles are held and transfer either to further sorting stations and/or finally to a station where those remaining are released on a further conveyer. Figs. 2 and 3 show the machine in which bottles are conveyed along conveyer 10 to be picked up in the pockets 17 of a pocketed wheel 16 and fed to a first sorting station A at which feeler arms 55, 56 and 67 engage surfaces of the bottle and indicate, by virtue of the arms coupling to a micro-switch 63, Fig.3, whether the bottle diameter is above or below a specific value. Bottles above the specific diameter cause the momentary release of the switch plunger 64 which causes the momentary changeover of switch contact 63a to charge capacitor 82 which, when the switch returns to its normal condition, pulses relay 80 to operate solenoid 93 to shift spool valve 37, as shown in Fig. 3, to communicate vacuum maintained in central chamber 31 of the transport wheel to the suction cup 33 engaging the bottle at the sorting position. The bottle is thus carried around in the pocket of the wheel to a second sorting station B while smaller dimensioned bottles, which do not release switch plunger 64, are carried away from the sorting station on conveyer 10. At station B the bottles are gauged to a different limit in order to sort a particular type of bottle from the remainder, such a bottle when detected operates a switch 115 which, in a similar fashion to that at station A, causes the operation of a solenoid 118, and the spool valve 37 appropriate to that bottle, to release the vacuum in the suction cup 33 so that that bottle travels away from the wheel on conveyer 101. The remaining bottles travel on the wheel to a further sorting station C. Again a particular type of bottle is detected, e.g. by neck height, and such bottles released by the holding suction cup to travel away on conveyer 110 while the remaining bottles travel along to station D where vacuum is released from the suction cups by a cam 123, which resets all the remaining operated spool valves, and allows the remaining bottles to feed away from the machine on conveyer 122.

Title: Improvements in and relating to sugar refining
Inventor: BENNETT MICHAEL CAMM
IPC: C13B20/14
Filed: 1967-09-29
Abstract: 1,224,990. Refining sugar. TATE & LYLE Ltd. Sept.27, 1968 [Sept.29, 1967], No.44594/67. Heading C6B. In a method of refining an undefecated sugar liquor, a floc is caused to form in the liquor by incorporating a cationic surfactant, the floc being then separated from the liquor to yield a clarified liquor which may then be subjected to further refining by conventional methods. Preferred surfactants are the dialkyldimethyl quaternory surface active agents known as Arquad 2HT, Noramium M2SH and Aliquat H226, which are ditallowdimethyl ammonium compounds predominantly dioctadecyl and dihexadecylammonium chlorides. Butyltrimethylammonium bromide may also be used but the amount is critical since an excess causes the floc to redissolve. As shown in Fig.1, the method is combined with a phosphatation process, inlets 1, 2, 3, 4 to a reactor 5 being supplied with sugar liquor, surfactant, phosphoric acid and lime, respectively, the sugar liquor being either raw sugar or melter liquor obtained from an initial centrifuging of the raw sugar. The mixture is maintained at a temperature of 85-90 degrees C. for about ten minutes in the reactor 5 and is then passed via an intermediate chamber, where it is aerated by air fed in through line 6, to a weir tank 7 from which it is discharged to a settler tank 8, the aeration assisting in the separation of the floc which rises to the top of the settler tanks as a scum or foam. In a modification Fig.2 (not shown), fresh or recycled powdered carbon, in the form of a carbon-liquor slurry, is added to the reactor chamber in addition to the sugar liquor, surfactant, lime and phosphoric acid, the floc is separated in a first filter, and a polish filtration reactor receives the resulting liquid, with the addition of more carbon-liquor slurry, the liquor being retained in this reactor for about 30 minutes to affect further refining of the liquor, after which a second filter removes the carbon-liquor slurry for recycling and passes the liquor to a crystallization apparatus. Graphs, Fig.3 and 4 (not shown) illustrate respectively the saving in cost which can be achieved using various combination processes, and the relationship between colour density and percentage of the various preferred surfactants.

Abstract: 1,274,448. Beaming machines; stop motions. COURTAULDS Ltd. 22 Sept., 1969 [23 Sept., 1968], No. 45070/68. Heading D1M. A warp stop motion in a beaming machine comprises a plurality of thread breakage detection devices D A , D B , D C , each device comprising an array of thread switches ST connected in parallel and a warning lamp L for each device indicating closing of a switch ST in that device, which closure produces stopping of the motor of the machine. In Fig. 1 the circuit is in its normal operating state, switches X 1 , X 2 , being controlled by relay X and Y 1 , Y 2  by relay Y. When any thread switch ST closes on thread breakage, current from supply terminals L 1 , L 2 , flows through switch S, and relay X to switch over contacts X 1 , X 2 , cutting off the supply to the drive motor. Switching of contact X 1  energises relay Y to switch contacts Y 1 , Y 2 , and switching of contact X 2  energises terminal C, to energise switch S 2  of the device with the closed switch ST, and via resistor R 4  terminal D, the current from which flows through lamp L, without lighting it, to keep switch S, energised. Switching of contact Y 1  deenergises terminal B, and hence all the switches S 1  of the devices other than the one with a closed switch ST, and switching of contact Y 2  shorts out resistor R 4  and applies full voltage to lamp L of the device with the closed switch ST to light the lamp, thereby indicating in which group of threads the break has occurred. The switches S 1 , S 2 , may be solenoid switches or transistor switches, the circuit of each device D A  ... D C  then being as described in Specification 1,274,447.

Abstract: 1346680 Making elastomeric bushes; coiling helices CATERPILLAR TRACTOR CO 4 Oct 1971 [5 Oct 1970] 46101/71 Headings B3A and B3E [Also in Division F2] In a cylindrical laminated bush 10 comprising concentric elastomer and metal cylindrical shells 15, 14 the or each metal shell 14 is formed by winding strip helically with the edges of one convolution abutting the next. Successive metal shells 14 are oppositely wound. The metal may be brass plated steel shim and the elastomer silicon rubber. The rubber may be bonded to the metal strip before winding to give a composite rubber/metal shell, or the metal shell may be wound first and the rubber shell built up on it and cured and bonded in situ. A "curl" may be placed in the steel strip as it is wound so that it does not unravel. A guide 31 back bends the steel strip as it is drawn across the edge 32 of a sharp-edge die 30 on its way towards the mandrel of a winding machine (Fig. 9, not shown). By controlling the tension on the strip and the spacing between the die and the guide, it is possible to obtain a "curl" whose diameter D 1  in a free state is less than the diameter D of the cylindrical metal shell 14 formed from the strip.
