Title: Anion-exchange resins and their production
Inventor: NOLAN JOHN DEVEREAUX
IPC: C08F8/32
Filed: 1964-03-25
Abstract: Anion exchange resins contain as exchange groups, tertiary amino groups of formula -N(ROH)2, where R is -(CH2)nwhere n is 2-6; or -C2H4(XC2H4)n-, where n i 1-3 and X is a divalent atom or radical of two atoms, e.g. -O-or-NH-; in all cases the nitrogen atom being attached to the resin matrix by its free valence.  The resin may be based on a polymer of styrene cross-linked with divinyl benzene.  In an example, styrene was polymerized in suspension with ethylene glycol dimethacrylate as cross-linking agent, swollen with ethylene dichloride and chloromethylated, the polymer beads were then treated with diethanolamine to produce the anion exchange resin which could be used to demineralize water containing organic matter.

Title: Numerical control system
IPC: G05B19/25
Filed: 1968-03-18
Abstract: 1,219,303. Programme control of machine tools. PRATT & WHITNEY Inc. March 18, 1968, [April 17, 1967], No.13014/68. Heading G3N. A numerical control system having a pulse responsive servosystem for driving an object to an end point controls the velocity of the object by comparing a numerical representation of the position error with a numerical representation of a desired velocity of movement and developing a train of pulses having a rate proportional to the smaller numerical representation which is applied to the pulse responsive servosystem. As shown, movement instructions for machine parts 14-16 are encoded on a tape 17 which is read by a reader 18 decoded by a decoder 19 and charged into binary form by a translator 20. The output of the translator is fed to binary re-circulating command registers 23-25 allocated to the coordinate axes. The control arrangements for the axes are similar and for the X-axis the position of the machine part 14 is determined by an electrooptical quantizer 27 generating discrete pulses each indicative of unit axis movement. The quantizer pulses are fed to a binary re-circulating position register 31 and their sum compared with the contents of the command register 23 by comparator 34. The output of the comparator is applied to an error frequency generator 46 having a.pulse output which has a frequency proportional to the position error and is applied to one input of a frequency selector 43. The other input to selector is derived from a generator 40 the pulse output of which has a frequency proportional to the feedrate commanded by the tape. The selector 43 selects the lowest input pulse rate to control an X-axis servo 11 so that the machine part moves towards the commanded position at a constant feedrate until the position error falls to a value at which the pulse rate of generator 46 is below that of generator 40 after which the machine part is finally positioned at a feedrate proportional to position error. The commanded feedrate is derived from a clock oscillator 37 the output of which is applied to a binary frequency generator 38, comprising a counter chain of bi-stable multivibrators, providing a plurality of pulse trains that do not overlap. The pulse trains are fed through a manually adjustable feedrate control 39 to a generator 40 which multiplies the selected pulse train from control 39 by a number received from a storage register 19, set in dependence on the commanded feedrate by the translator 20.

Abstract: 120,877. Soc. Anon. des Etablissements L. BlÚriot. Nov. 23, 1917, [Convention date]. Regulation, automatic systems and apparatus for.-A number of regulators with their contacts in series are brought into action successively and act one at a time to regulate on field circuit resistance according to the supply voltage or current. Four vibrating regulators are shown in Fig. 1 with their contacts g' - - g' controlling the resistances d<1> - - d<4>. The operating-windings h' - - h<4> are connected across the generator armature a, and each winding is in series with a resistance which is short-circuited when the regulator armature is in its unattracted position. The operating-windings h<2>, h<3>, h<4> are also in series with resistances j<1>, j<2>, j<3> respectively, which are short-circuited by auxiliary switches k<1>, k<2>, k<3> when the preceding regulator is attracted. At first, the regulation is effected by the regulator e<1>, but as soon as the resistance d<1> becomes insufficient with the contacts g' held open, the regulator e<2> is affected. The resistance j' is short-circuited and the coil h<2> starts the arm e<2> vibrating. While the contacts g<2> are open, the coils l<2> are supplied with current and lock the regulator e<1> with its contacts open. If the introduction of the resistance d<2> is insufficient, the regulator e<2> stays in its attracted position and the resistance j<2> is short-circuited, thereby enabling the regulator e<3> to operate. The last regulator may be arranged so that, in its attracted position, it connects a resistance across the dynamo terminals.

Title: Improvements in and relating to the production and purification of salicylic acid or?-cresotinic acid or their salts
IPC: C07C51/43
Filed: 1930-04-29
Abstract: Sodium salicylate is recovered from crude solutions by crystallization at a temperature below the dehydration temperature of the hexahydrated salt, i.e. below 20 DEG  C.  The crystals so obtained, after removal of mother liquor and washing with cold water, may be dehydrated at a low temperature, preferably in vacuo, to yield a purified sodium salicylate, or they may be dissolved in water and acidified to yield a relatively pure salicylic acid; in either event, the hydrated salt may first be further purified by recrystallization. The crystallization may be facilitated by seeding the solution with a small amount of the crystalline hydrated salt, and details are given of the initial preparation of a small amount of the hydrated salt from the commercial anhydrous salt.  An example is given also describing the treatment of crude sodium salicylate prepared by carbonating sodium phenolate.  The processes described above may be applied to the treatment of sodium o-cresotinate, the trihydrate of which is stable up to about 50 DEG  C.

IPC: B29C35/04
Filed: 1926-05-27
Abstract: 276,430. Laursen, L. A. May 27, 1926. Vulcanizers; cores &c. for.-Rubber tubes are vulcanized by mounting them on imperforate hollow poles or mandrels 45, Fig. 2, sealing the ends of the tubes to the mandrels bv means of rubber bands 46 without expelling the air trapped between the tubes and the mandrels, and vulcanizing in direct contact with water without external confining means. The mandrels are placed in a heater 1 closed at one end and provided at the other with a removable door 2, into which water is pumped through a pipe 3 having apertures 4 on its upper sides so that the water is sprayed on to the tubes. A continuous flow is obtained by draining off the water through a pipe 9 and pumping it from a hot well 8 back again by a pump 6 and return pipe 5. The temperature of the water is maintained by admitting steam through a pipe 14 and cold water may be admitted through a pipe 12. Steam is also admitted to the bottom of the heater through a pipe 18 controlled by a valve 17 and provided with apertures 19. The heater may also be provided with a heating casing 21 supplied with steam from a pipe 22 and with a drain pipe 40. The tubes may be vulcanized under pressure by admission of compressed air from a tank 26 through a pipe 23 having, a regulating valve 24 adapted to close automatically when the pressure exceeds 150 lbs. per sq. inch. A vertical pipe 28 leads to a header pipe 29 provided with a valve controlled vent pipe 30, a safety valve 32 and relief and control valves 33, 35, 36. The temperature in the heater is controlled thermostatically by temperature bulbs 37, 22<c> operating valves 17a, 22<b>. A quantity of soapstone is placed in the heater before commencing vulcanization and the rubber is softened by a preliminary steam heating to 212‹ F. for about 3 minutes. After vulcanization the tubes are cooled slowly by spraying with water. A modified apparatus is also described in which the vulcanizer is heated by a coil placed within the chamber and the hot water from the hot well is re-circulated by means of an injector nozzle. Specification 276,431 is referred to.
