Title: Improvements in the preparation of hydroxyalkyl polyphosphate
IPC: C08G18/50
Filed: 1967-03-01
Abstract: 1,138,663. Poly(hydroxyalkyl) polyphosphates. UPJOHN CO. 1 March, 1967 [4 April, 1966], No. 9720/67. Heading C2C. A poly(hydroxyalkyl) polyphosphate is obtained by reacting a 1,2-alkylene oxide with a polyphosphoric acid having a calculated P 2 O 5  content of substantially 75% by weight or more, the reaction being carried out by admixing the polyphosphoric acid with a major proportion by weight of a said poly(hydroxyalkyl) polyphosphate obtained as the end product of a previous batch and reacting the mixture so obtained with the alkylene oxide. The polyphosphoric acid starting material preferably has a P 2 O 5  content of 78 to 88% by weight and the process may be carried out in a semi-continuous manner by retaining part of the product of each batch as finished product and using the other portion as reaction medium for the succeeding batch. The reaction is suitably effected at between 60‹ C. and 150‹ C., preferably between 80‹ and 130‹ C. The initial batch of alkoxy lated polyphosphoric acid used as reaction medium can be prepared by carrying out a reaction of a polyphosphoric and the alkylene oxide in a solvent such as dioxane or by alkoxylating a polyphosphoric acid such as 105% phosphoric acid which is of a viscosity lower than that which prevents adequate mixing of the reactants and using the resulting product as solvent in the phosphorylation of a polyphosphoric acid having a P 2 O 5  content of at least 75% by weight, the resulting product being then employed in the alkoxylation of a second batch of polyphosphoric acid having a P 2 O 5  content of at least 75% by weight. Specified alkylene oxides are ethylene-, propylene-, 1,2- butylene-, and 1,2-hexylene oxides, epichlorhydrin, epibromhydrin, 1 - chloro - 2,3 - epoxybutane and 1-chloro-2,3-epoxy hexane, and two or more of such alkylene oxides may be used either simultaneously or sequentially. The products have a higher ratio of phosphorus content to hydroxy groups than in the previously known products of this type and are useful as intermediates for the production of polyurethanes.

Title: Method of, and apparatus for, the form dressing of grinding wheels
Inventor: ZEISE GUENTER
IPC: B24B53/08
Filed: 1957-03-26
Abstract: 820,090. Trueing grinding wheels. KLINGELNBERG, G. JAEGER, G. KLINGELNBERG, H. W. and BAUM, CO. [trading as KLINGELNBERG SOHNE W. F.]. March 26, 1957, No. 9840/57. Class 60. A method for the form dressing of a grinding wheel 1, Fig. 1, used for the form grinding of worms comprises mounting a generator dressing attachment in the workhead spindle 2 of the grinding machine to dress one flank of the grinding wheel, using this dressed flank to plunge-cut grind a template 18, Fig. 4, and employing this template in a template-controlled dressing device, Figs. 9 and 10, to form dress both flanks of the grinding wheel. One flank of the grinding wheel is dressed by a diamond 10, Fig. 1, carried on a rest 11, which can be transversely adjusted to the base circle diameter of the worm to be ground on a slide 9 carried on guide rods 8 ; the rods 8, can be adjusted to the lead angle of the worm by a swivel arm 7 mounted in a quadrant 4 secured to the workhead spindle 2. The dressed flank of the grinding wheel is then used to plungecut grind a template 18, Fig. 4, mounted on a swivel arm 17 in a bracket 12 disposed between the centres of the grinding machine ; the swivel arm can be adjusted in a quadrant to the lead angle of the worm, and the bracket can be set horizontal by means of a spirit level 15. The template 36, Fig. 9, so formed, is clampled by a member 35 to the form dressing device wherein it imparts axial movement to a follower 34 during the back-and-forth movements of a valve 30 in guides 29. The follower is adjustablysecured to a sleeve 33 having a slotted cooperation with an eccentrically-mounted pin 38 to rotate a shaft 40. The opposite end of this shaft is connected to a disc 41 carrying two eccentric pins 42, 43, Fig. 10, engaging slots in guide-bars 46, 47 to which are attached dressing diamonds 50, 51 operative on the grinding wheel. The diamond 51 thus follows the contour of the template 36, and the diamond 50 a mirrorimage of the contour, to dress both flanks of the grinding wheel during the movements of the valve 30. The guide-bars and diamonds are spring-urged apart to eliminate backlash between the template and the diamonds. The back-and-forth movement of the valve 30 is controlled by a hydraulic plunger 31 to which it is connected by a peg 32 ; springs 54, 55 retain the valve 30 in its top position when the hydraulic pressure is removed. During the movements of the plunger 31, a pin 59 causes rotation of a sleeve 57 and rod 58 to rock a diamond 61 across the periphery of the grinding wheel. The template dressing device may be adjusted radially of the grinding wheel by hand through a screw 62 or by power through a pinion 63 and feed screw 64.

A process for the production of oxygen from air by rectification in two juxtaposed high and low pressure columns 2, 5 comprises condensing under the high pressure at least a portion of nitrogen leaving the column 2 in a condenser 4 disposed in the column 5 and cooled by indirect heat exchange by liquid oxygen in a bath 6, using at least a portion of this condensed nitrogen for reflux in the column 5 and transferring by means of a pump 7 either condensed nitrogen or liquid oxygen from the low pressure column 5 to the high pressure column 2, e.g., through ducts 24, 3 for effecting condensation of nitrogen ascending therein. Oxygen rich liquid from the bottom of the column 2 is expanded at a valve 9 and enters the column 5 at an inlet 10, and gaseous oxygen and nitrogen products leave through ducts 14, 15 respectively. When liquid oxygen is transferred from column 5 it traverses a condenser at the top of column 2 thereby condensing nitrogen ascending therein and being itself vapourized to yield gaseous oxygen product and also feed for the column 5. The pump 7 is of the centrifugal kind with a vertical shaft driven from above and is so disposed that the pressure set up at the suction inlet is not lower than that above the indrawn liquid and the duct 24 is so arranged that any vapours formed in the pump 7 can gain access to the liquid collecting chamber.
