Title: Improvements in or relating to the production of paint vehicle bases
IPC: C08G59/42
Filed: 1954-09-19
Abstract: A paint vehicle is obtained by heating a glycidyl ether of a polyhydric phenol having at least one -OH group and from 1-2 epoxy groups per mol. with a fatty oil having an iodine number of 70-220 at 75 F. until a clear solution is obtained and then heating the product with 5-15 per cent by weight of a dicarboxylic acid or anhydride until incipient gelation occurs whereupon the product is thinned with a hydrocarbon thinner.  The product obtained in the first stage may be heated with 3-20 per cent by weight of a monocarboxylic acid to reduce the iodine number by about 50 per cent.  The glycidyl ether has preferably 3-10 -OH groups and 1.4-1.9 epoxy groups per mol. and the heating with the fatty oil is carried out in presence of an alcoholysis catalyst.  The glycidyl ethers are prepared by reaction of epichlorhydrin with the usual dihydric phenols, e.g. resorcinol, hydroquinone and polynuclear phenols.  A table is given of the Durrans' m.ps., hydroxyl, epoxy and esterification values of the products used.  Fatty oils specified are soybean, linseed, corn, cottonseed, hemp, kapok, herring, perilla, poppy, pilchard, menhaden, mustard, peanut, rape, sardine, safflower, sesame, oiticia, walnut, tung, dehydrated castor and heat bodied linseed oils.  Polyhydric alcohols, e.g. pentaerythritol, are preferably present during the action with the fatty oil.  The monocarboxylic acids used have at least 6 C atoms, e.g. the free acid of the aforementioned oils; other suitable acids are caproic, caprylic, 2-ethylhexoic, lauric, palmitic, stearic, oleic, benzoic, p-ter.-butylbenzoic, naphthenic acids, cinnamic, hydrogenated rosin.  The dicarboxylic acids specified for the second stage are malonic, succinic, sebacic, glutaric, azelaic, sebacic, maleic, phthalic, tetrahydrophthalic, hexahydrophthalic, diglycolic, dimerized drying oil fatty acids, dimerized rosin, Diels-Alder adducts of maleic anhydride with diolefines, e.g. terpenes and cyclopentadiene, petrex acids.  In examples (1) a polyether obtained from epichlorhydrin and bisphenol is reacted at 555 DEG  F. with a soybean oil having an iodine no. of 130.  The product is further reacted with soybean acids and adipic acids until gelation starts whereupon a solvent consisting of 75 per cent paraffin and 25 per cent naphthenes is added.  The base obtained is used to make up pigment mixtures of (a) titanium dioxide calcium carbonate and aluminium stearate; (b) red iron oxide, black iron oxide, calcium carbonate and aluminium stearate. Specification 737,272 is referred to.

IPC: B23H7/18
Filed: 1967-06-13
Abstract: 1,188,546. Electrolytic machining. PRODUCTION ENG. RESEARCH ASSOCIATION OF GREAT BRITAIN. June 13, 1967, No.27188/67. Addition to 1, 081,901. Heading C7B. In a pure forming method or a combined forming and generating method of electrolytic machining, the operation is controlled so that subsequent and only subsequent to the attainment of an equilibrium condition between the tool and workpiece at at least one point, the end gap formed between the tool and workpiece as a result of the infeed movement is reduced at every point and so that there is a very narrow gap at the end of the operation. Once the reduction in gap has been initiated it may then be continuously reduced throughout the rest of the operation or it may be reduced in one or more steps. The reduction in gap may be effected by reducing the voltage drop between the tool and workpiece and this may be controlled by reference to the tool position. An adjustable voltage stablilized power pack may be used. A decrease in infeed rate may be combined with the reduction in voltage, the latter being sufficient to ensure that the gap reduces.

Title: Controlling the Regeneration of Catalyst in a Fluid Catalytic Cracking System.
IPC: G05D21/00
Filed: 1967-06-15
Abstract: 1,182,180. Automatic control. TEXACO DEVELOPMENT CORP. June 15, 1967 [June 27, 1966], No.27619/67. Heading G3R. In a system for regenerating catalyst in catalytic cracking, combustion air flow to a dense bed of the material is automatically controlled to maintain a temperature differential, dependent on the temperature of the dense bed, between the dense bed and a zone above it in which afterburning takes place. In Fig. 1, hydrocarbon from a supply 34 is maintained at a constant rate of flow by automatic control of a valve 36, raised to a constant temperature by a pre-heater 42 having an automatically controlled fuel valve 46, and supplied through a conduit 24 to a catalytic cracking reactor 12. The level of a fluidized bed 14 within the reactor is regulated by automatic control of a valve 58 in a conduit 56 through which spent, carbonized, catalyst is fed to a regenerator 16. The spent catalyst is entrained by a constant flow of air supplied from an automatically controlled turbinedriven compressor 62. Automatically controlled flows of combustion air and water are supplied to a fluidized bed 18 within the regenerator through conduits 98, 92 so that the carbon is burnt off the catalyst. Further burning of CO occurs in the space above bed 18 and an automatically controlled flow of mixed steam and water is supplied through a conduit 78 and cyclone 70 to cool this space. Pressure within the regenerator is maintained constant by automatic control of a valve 76 in flue gas conduit 72. Regenerated catalyst is withdrawn through a conduit 20 and added to the hydrocarbon supply to the reactor in conduit 24. The temperature of the mixture is regulated by automatic control of a valve 22 in conduit 20. Products from reactor 12 pass in vapour form through a conduit 23 to a fractionator 25 which produces a vapour stream at 27, a gas-oil product at 29, and a residium product at 35. A gas-oil product is also recycled to the input of the reactor by a pump 33, flow in the return conduit being maintained constant by automatic control of a valve 55. Detectors 110, 114 responsive to bed and overhead temperatures in the regenerator supply signals to a digital or analogue computer 32 which compares the temperature difference with a predetermined temperature difference and corrects any error by controlling, through a pneumatic regulator 111, the rate of flow of combustion air to the regenerator. The predetermined difference is, however, automatically adjusted within the computer according to specified functions of temperatures, rates of flow and other factors, signals corresponding to which are either supplied to the computer from detectors through the lines shown broken in Fig. 1, or are programmed into the computer.

Abstract: 849,153. Stretching. LOEWY ENGINEERING CO. Ltd. Sept. 5, 1957 (Sept. 10, 1956], No. 27665/56. Class 83 (4). A stretching - machine comprises a pair of spaced relativelydisplaceable gripper-heads 1, 2, power means 4 for displacing one of said gripper-heads 1 in a direction away from the second gripperhead 2, a pair of longitudinal frame members 7 extending parallel to the direction of the applied stretching force and slidably positioning said second gripper-head in relation to the first, and at least one longitudinallydisplaceable tow-bar 14 movable in opposite directions and arranged parallel to said frame members, said bar being provided with a series of holes 15 in which a locking-pin 16 projecting from the second displaceable gripper-head may be caused to enter, and further comprising means 8 for anchoring said second gripper-head in relation to said frame members. To move the gripperhead 2 along the frame members 7, hydraulic rams 18, Fig. 3, on the gripperhead 2 are operated to lift locking-rods 8, which pass through holes in lateral gripper-head extensions 13, up from elongated holes 9 in the frame members 7. These members 7 each comprise upper and lower beams joined at one end and are embraced by the gripper-head extensions 13. Hydraulically-operated locking-pins 16 in the head 2 are then moved outwardly to enter into holes 15 of series in tow-bars 14, positioned between the superposed beams of the frame members 7, which are then moved longitudinally, the distance between adjacent holes 15, by hydraulic rams 17A. The locking-pins 16 are then withdrawn from the holes 15 and the tow-bars 14 move back to their original position so that the pins 16 lie opposite the next pair of holes 15 into which they are entered so that the head 2 may be moved another step. When the head 2 has been moved the required number of steps it is locked to the frame members 7 by the rods 8. Specification 845,417 is referred to.
