Patent GB-761757-A (GB)
Title: Alginate pastes
IPC: A61K47/36
Filed: 1953-02-23
Abstract: Readily spreadable pharmaceutical pastes and the like are prepared by dissolving a comminuted, solid, water-soluble alginate in an aqueous solution of a salt of a metal, the alginate of which is water-insoluble, in a quantity in excess of the stoichiometric equivalent of the quantity of said salt in said aqueous solution, the concentration of said salt in said aqueous solution not exceeding 2 per cent, and preferably 1 per cent, by weight and the solubility of said in water under the operating conditions being not less than 1 gram per 100 millilitres water and such that it dissolves completely in water at the concentrations used.  In the case of salts more readily soluble than the alginate, both alginate and salt may be added simultaneously to the water and the mixture stirred until the reactants have dissolved.  In general, the quantity of salt used should be not less than 1 per cent and not more than 50 per cent of the stoichiometric equivalent of the quantity of alginate used. Specified alginates are the alkali metal, magnesium, ammonium, amine, alkyolamine and glycol alginates.  Specified coagulating salts are those of the alkaline earth metals (other than magnesium), aluminium, iron, lead, nickel and zinc; especially calcium acetate, benzoate, chloride, lactate, nitrate nitrite, propinate, salicylate and calcium salts of organic acids having dissociation constants not exceeding 1.55 X-10-4.  The pastes consist essentially of water, a water-soluble alginate, a water-insoluble alginate and a water-soluble salt of the basic component of said water-soluble alginate with an acid which forms a readily water-soluble salt with the basic component of the water-insoluble alginate.  Optional ingredients are oils, powders, perfumes and colouring matters.  The preparations may be in the form of powders capable of forming the pastes when dispersed in water.

Abstract: 1,088,852. Billet piercing. LOEWY ENGINEERING CO. Ltd. Jan. 15, 1965 [Feb. 7, 1964], No. 5348/64. Heading B3H. A hydraulic piercing press comprises a stationary base 10 supporting a holder 11 for the workpiece B, a piercing tool 42 mounted on a movable upper crosshead 40 connected by columns 43, 44 to a lower movable crosshead 30, a movable back up crosshead 20, disposed between the base and the lower crosshead 30 and carrying a back-up stem 16 for supporting the workpiece during piercing, and a hydraulic drive 31, 32 for the piercing tool arranged partly on the back-up crosshead 20 and partly on the lower crosshead 30. The billet holder 11 is slidable transversely on rails 12, 13 from a charging position into the press axis. Billet B is first upset by a tool 52 mounted on an intermediate crosshead 50 which moves initially with the piercing tool due to the insertion of hydraulically operated gags 53 actuated by hydraulic rams (54), Fig. 2 (not shown). The gags are then withdrawn and the piercing tool 42 is pressed through the billet by pressure liquid supplied to four cylinders 31, carried by the lower crosshead 30, through hollow pistons 32 carried by the back-up crosshead 20; this ensures that the back-up stem 16 is pressed upwardly into surrounding die 15 during piercing. Finally connectors 45 on the moving columns 43 engage sleeves 49 abutting the back-up crosshead 20 to lower it thus removing the back-up stem and allowing the tool 42 to punch out the remaining web of billet metal. The tool 42 is then raised by retracting rams 37, 38 whilst the billet is held down by tool 52 under pressure from two hydraulic rams 56. Finally the connectors 45 engage the crosshead 50 to raise the tool 52; this is assisted by pressurization of cylinders 58. Billet holder is then moved to an inoperative position where the pierced billet is ejected, the holder 11 cleaned and lubricated, and a new billet inserted. The back-up crosshead 20 may be raised independently by hydraulic rams 23, 24, Fig. 4 (not shown), or it may be lowered against stops 29 by hydraulic rams 26, 27.

Title: Improvements in or relating to apparatus at printing telegraph subscriber stations
IPC: H04L12/02
Filed: 1954-02-26
Abstract: 740,216. Telegraph exchange systems. CREED & CO., Ltd. Feb. 26, 1954 [March 7, 1953], No. 5733/54. Class 40 (3). In a telegraph system comprising subscriber equipment including a motor and a manuallyoperated perforating device, operable when the telegraph line is disconnected, the speed of the motor is increased above that employed during the normal printing operation when the device is to be operated. The motor 1 with serieswound windings 2, 3 is maintained at the appropriate speed during normal operation by a governor-controlled contact 4 which is opened when the speed rises above normal to switch in a resistance 5. When the perforating apparatus is to be taken into use a contact 6, closed by a supervisory relay, short-circuits the control by contact 4 and resistance 5 so that the speed of the motor increases. If the increased speed is to be limited, a coarse regulator device opens a contact 7 to introduce a resistance 8 into the motor supply circuit. When contact 6 is opened for the resumption of the normal printing operation, the resistance 5 is effective to reduce the speed of the motor until it again comes under the joint control of the contact 4 and the resistance 5.
