Abstract: 500,642. Purifying liquids; humincontaining substances. UNITED WATER SOFTENERS, Ltd. 'May 6, 1937, Nos. 12983 and 12984. Void. Convention dates, May 7, 1936 and May 7, 1936. [Class 46] [Also in Group IV] The . base-exchange capacity of natural or artificial humic materials is increased by subjecting the materials to the action of hot water or steam. Peat, lignite, or coal may be treated either in the natural state or after chemical treatment, for example with acid or with dehydrating and oxidizing agents. The material is granulated and preferably moistened and a stream of boiling water or steam, which may be under pressure, is passed through it. The treatment is more effective if carried out in the presence of an electrolyte. Suitable alkaline electrolytes are caustic soda potash, ammonia, lime, baryta, and alkali carbonates and bicarbonates. Neutral electrolytes such as sodium chloride, sodium sulphate, and calcium chloride, may be used; also acid electrolytes such as hydrochloric sulphuric or phosphoric acid. The material may be moistened with a solution of the electrolyte. The material may be subjected to a final dry heat treatment in vacuo at a temperature of 50 to 350‹ C.

Title: Improvements in machines for driving tacks into boots and shoes
IPC: A43D5/12
Filed: 1925-05-20
Abstract: 246,001. Lawson, O. L. May 20, 1925. Nailing, hand tools for; loose-nailing. - A tacking device for operating on boot soles is provided with means to curve the point of the tack as it enters the work. In the hand tacker shown in Fig. 4, the usual plunger 11 spring held in a casing 10 carries a driver member 12 on which is loosely mounted a sleeve 19 normally held downwardly against a pin 12<x> bv a spring 26. Pivoted to the sleeve 19 are spring held tack jaws 31, 31<x> the lower ends of which are shaped as shown in Fig. 6. Tacks are fed one at a time to the jaws 31, 31<x> from the usual raceway 22 by a separator 30, the arm of which is operated by the pin 12<x> on the driver 13. An arm 36 pivoted to the jaw 31<x> is adapted to be moved by a cam 38 so that its lower, curved end contacts with the lower curved part 42 of the jaw 31. When the plunger 11 is operated the jaws 31, 31<x> are lowered, by pressure of the spring 26, to engage the work, the cam 38 operating the arm 36 to bend the point of the tack against the curved surface 42. The member 12 then descends further against the spring 26 and the driver 13 drives the tack which is continuously curved by the surface 42. The tack jaws are permitted to yield at this time for the passage of the driver as stops on the jaws have disengaged from stop surfaces on the casing 10. In a modification, the tack jaws do not move downwardly to engage the work, and the arm 36 is dispensed with, the lower ends of both tack jaws being curved and grooved in order to bend the tack. The separator is operated by a separate member carried by the plunger 11. In another modification, the tack guiding jaws are angularly disposed with respect to the passage-way for the driver.

The slag is allowed to become solid or pasty and is retained in the converter; lime is added followed by a charge of crude iron having .C.3.4-4 .Mn.0.8-1.3 .Si.0.3-0.6 .P.1.5-2 .S.0.04-0.08 .Fe.balance which is then refined. A pasty intermediate slag may be obtained by using in the first stage a substantial excess, e.g. 60-100%, of lime over that normally used, or by adding to the normal slag a material containing carbon, such as granulated pig iron or iron-carbon briquettes. The initial charge is preferably pre-refined by top blowing with a blast containing 40-80% oxygen to reduce the silicon content to below 0.2%.

Title: Improvements in or relating to the preparation of monomeric glycol terephthalates
Inventor: VODONIK JOSEPH LEONARD
IPC: C07C69/82
Filed: 1953-05-13
Abstract: Polyesters are produced by polymerizing monomeric glycol terephthalates which are prepared by reacting a glycol of the formula HO(CH2)nOH, where n is an integer of 2 to 10, with a dialkyl ester of terephthalic acid having 1 to 4 carbon atoms in the alkyl group in the presence of a catalyst mixture comprising lithium hydride and at least one glycol-soluble monocarboxylic acid salt of cadmium, magnesium and zinc.  The invention is exemplified in the reaction of ethylene glycol with dimethyl terephthalate which polymerizes to polyethylene terephthalate.  Mixtures of esters, e.g. incorporating dimethyl sebacate, may be reacted.  Polymerization catalysts, e.g. cobaltous acetate and antimony trioxide, may be included in the above catalyst mixture for continuous production of the polymers.ALSO:Monomeric glycol terephthalates are prepared by reacting a glycol of the formula HO(CH2)nOH, where n is an integer of 2 to 10, with a dialkyl ester of terephthalic acid having 1 to 4 carbon atoms in the alkyl group, preferably at atmospheric pressure, in the presence of a catalyst mixture comprising lithium hydride and at least one glycol-soluble monocarboxylic acid salt of cadmium, magnesium or zinc.  Suitable salts are those of propionic, butyric, valeric, stearic, lauric, salicylic and lactic acids.  The invention is particularly exemplified in the preparation of bis-2-hydroxy-ethyl terephthalate by reacting ethylene glycol with dimethyl terephthalate.  Mixtures of esters, e.g. incorporating dimethyl sebacate, may be reacted. Concentrations of lithium hydride are generally between 0.003 and 0.05 per cent and of the organic salt between 0.005 and 0.1 per cent, based on the terephthalate.  Reaction temperatures of 110 DEG  to 260 DEG  C. are used.  The reaction may be carried out continuously, using a cylindrical tower containing a number of individually heated plates and having on top a condenser maintained at the boiling point of the alcohol released.  The top plate is kept at 160-170 DEG  C. and the lower ones are progressively hotter.  The reaction mixtures and catalyst are fed in at the top plate.  Catalysts for subsequent polymerization of the terephthalate, e.g. cobaltous acetate and antimony trioxide, may be incorporated with the ester-interchange catalyst mixture.

Abstract: 958,053. Typewriters. SPERRY RAND CORPORATION. Sept. 27,1961, No. 13378/62. Divided out of 958,052. Heading B6F. Platen and feed-roller rotation for bill form.- The platen rotating mechanism in Fig. 2, for a typewriter, so that a bill form may instantly be brought into the correct position for the first line of typing, comprises an arcuately serrated support plate 62 mounted detachably on a carriage frame 16, and carrying on a pivot 66 a gear segment 64 with an integral lever 65 and a throw adjusting lever 70. Pivotally mounted on said lever is a throw-adjusting stop 71 provided with shallow teeth 75 to allow the stop to be slid in an adjusting movement over corresponding serrations 76 on the support plate 62, continuous engagement being ensured by a spring 73 attached to the stop 71 and bow 70. On forward movement of the lever 65 the gear segment 64 rotates a drive gear 82, slidably mounted on a platen shaft 12, in Fig. 6, whereupon a drive dog 84 lying against an idler gear 83 and having teeth 84a is caused to engage a driven collar 80, also slidably mounted on the shaft 12 and keyed for rotation with the shaft by a pin 81, the rotation of the platen being arrested by a pin 67, on the segment gear 64, engaging first a cam 77 on the stop 71, to prevent its upward movement and disengagement with the serrations 76, and then abutting a stop edge 78. The engagement of the drive dog 84 with the teeth of the collar 80 is brought about by the relative movement of a collar 89 fixedly attached to the drive gear 82 and the idler gear 83 which forces the dog to slide in the slots 87, 88 into engagement. To prevent the idler gear from rotation, when the normal linespacing mechanism is operated, the idler gear 83 is yieldably arrested by a drag pinion 90, whose spring 92 (Fig. 1, not shown) supplies the necessary drag. To ensure correct setting of the space positions a detent mechanism (not shown) may be provided, so that when the lever 65 is allowed to return to its rest position under the force of a spring 93, the detent mechanism will rotate the platen in either direction, until a detent roller will settle normally in one of the spaces between the teeth of a ratchet-wheel (not shown).

The oxalated bovine plasma may be diluted with 0.85 per cent aqueous sodium chloride solution such that the plasma is present in an amount of 60 to 90 per cent by volume of the diluted plasma.  The pH may be adjusted by addition of an alkali metal hydroxide, and buffered using a sodium acetate-acetic acid, sodium succinate-succinic acid, sodium acid phthalate-phthalic acid, mono- or di-sodium phthalate buffer.
