IPC: C07C231/00
Filed: 1972-07-12
Abstract: 1384447 Salicylic acid ethers and xanthone-2- carboxylic acids SYNTEX CORP 12 July 1972 [12 Jan 1972] 32537/72 Heading C2C A (p-substituted-phenyl) salicylic acid ether, wherein the substituent is carboxy or an ester or amide thereof, is obtained by treating a (psubstituted-phenyl) salicylate with a strong base. Specified bases are alkali metal hydrides, hydroxides, alkoxides, carbonates and amides. The reaction is preferably conducted in polar solvents, and under conditions which discourage cleavage of the salicylate ester bond, e.g. under an inert atmosphere, and substantially anhydrous conditions. Examples are given which illustrate the process. A (p-substituted-phenyl) salicylate may be obtained by condensing p-hydroxybenzoic acid, or an ester or amide thereof with salicylic acid or the acid chloride thereof. Also the (p-substituted-phenyl salicylic acid ether may be cyclized to give the corresponding xanthone-2-carboxylic acid, or ester or amide thereof. The xanthone products are useful for inhibiting the effects of allergic reactions, also as smooth muscle relaxants or vasodilators. They may be administered in association with conventional pharmaceutical excipients.

Title: A method and a device for compensating weighing faults in feeders for carding machines
IPC: D01G23/04
Filed: 1948-12-17
Abstract: 655,023. Weighing apparatus. SANDELIN, O. E. Dec. 17, 1948, No. 32704. Convention date, Jan. 23. [Class 143] In an apparatus for feeding fibre to a carding machine of the kind in which an automatic feed weigher deposits batches of fibre on to a feed conveyer 12, travelling at a speed proportional to that of the carding machine, whereon it is compressed into a solid mat 28 by a reciprocating plate 26, variations in batch weights from a predetermined standard are compensated by causing the weigher to discharge on to the conveyer at intervals of such length that the distance through which the conveyer is moved during each interval is proportional to the weight of material weighed out during that interval. The feed to a weigh receptacle 7 is effected by a conveyer 2 the drive pulley 5 of which is normally clutched to a shaft driven by the carding machine, but is arranged to be disconnected on receipt of an electrical impulse at its magnetic clutch 6. The receptacle 7 is connected with an indicator arm 31 carrying a pair of contacts 37, 42 the former of which contacts a preset contact 33 on the dial and serves to disengage the clutch 6 and effect cut-off. To compensate for overloading of the receptacle after cut-off, when the arm 31 has stopped at some such position as shown, a second arm 40 driven at a speed proportional to that,of the carding machine and also therefore the conveyer 12, is swept across the dial until contacts 41, 42 meet and close a circuit which energizes a pawl release 44, a receptacle discharge release 11 and, the single revolution clutch 19 controlling the drive of the compressing plate 26. The arrangement being such that the distance moved by the conveyer 12 during the period when the arm 40 travels between the contact 33 and the arm 31, compensates for the overweight and thus ensures a uniform weight per unit length on the conveyer 12. The release of the pawl 50 from the driven ratchet wheel 39 on actuation of release 44, enables the arm to be rotated anti-clockwise by a spring against a stop, not shown, which reengages the ratchet and pawl. Discharge of the receptacle returns arm 31 to zero, and on restarting of the feed conveyer 2 a new cycle commences. To prevent premature operation of the discharge mechanism when contacts 41, 42 touch during the return movement of the arm 31, a time delay mechanism 46 is incorporated in the circuit. In a modification (not shown), the contacts are replaced either by mercury switches or by an arrangement of photo electric cells, light sources and light shutters.

Title: Method and apparatus for mixing materials forming viscous masses
IPC: B29B7/42
Filed: 1959-09-30
Abstract: 856,708. Mixing viscous masses. UNION CARBIDE CORPORATION. Sept. 30, 1959 [Oct. 9, 1958], No. 33233/59. Class 86 In the mixing of materials forming viscous masses, the constituents are first treated by a helix 46 which rotates and shears the materials as they move to the interior chamber 56 of the helix, the smaller diameter of which produces a compressing and accelerating action on the mass which is extruded through passages 57, at a still higher velocity, back into the helical treatment stage, the mass being thus re-cycled until mixing is complete. The process may be applied to a batch, the stator chamber 39 being removed for refilling with one or more of the constituents and one or more other constituents being introduced through the channel 58, e.g., in mixing polyureth-, ane foaming formulations a stream of CO 2  gas is admitted at 58. If a continuous process is desired, all of the ingredients are introduced through one or more passages 58. The outlet 51a may have a removable plug. The clearances between the helix 46 and the stator 39 aresmall, i.e., between 0.025 and 0.38 mm. and preferably between 0.025 and 0.25 mm., to produce the shearing action between the helix and the walls of the stator which are cooled by a coolant passing through a helical jacket 48 between an inlet 49 and an outlet 51. The temperature of the mass is sensed by a thermo-couple probe 55 extending into the chamber 56 and the mixing process is thereby controlled. Metal to metal face joints, sealed by O-rings 35, 39b are used, as the small clearances between the stator and rotor preclude the use of compressible gaskets. The rotordrive shaft 11 has an upper mechanical seal 13, with O-rings 14, cooled by water supplied through .passage 15, and a lower mechanical seal 44 with O-rings 45. CO 2  gas is supplied under slight pressure at 23b to prevent material leaking from the mixing space, or possible leakage of air around the seal 13.
