Title: Inductive stirring device for metallurgical furnaces
IPC: H05B6/32
Filed: 1953-08-07
Abstract: 721,121. Electric furnaces with inductive stirring. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 7, 1953 [Sept. 20, 1952], No. 21823/53. Class 39 (3) An inductive stirrer for a metallurgical furnace, i.e. an arc furnace, open hearth furnace or hot metal mixer, consists of two or more two-pole permanent or direct current excited magnets 4 mounted below the furnace on parallel, horizontal, synchronously rotating shafts 5, which are driven in the same direction. The pole axes of the two magnets are parallel or displaced in relation to each other by, at the most, 45 degrees, the distance between the shafts being at least twice the lengths of the magnets. The direction of rotation of the shafts may be reversed, and the speed of rotation is where T is the distance between the shafts in cms. and V the number of revolutions per second of the shafts. The metal shell 2 of the furnace within an area having a width at least twice as large as the axial length of the magnets and a length twice as large as the distance between the shafts is made from a non-magnetic material with a high electric resistance, e.g. non-magnetic steel. The stirrer and preferably the shell is arranged to be turned around a vertical axis through the furnace, and the stirrer may be arranged asymmetrically with respect to the vertical axis or plane of symmetry of the furnace or may be moved into such a position to achieve such a rotation of the surface of the charge as to facilitate deslagging. The magnets may have windings 6 and pole shoes 7.

Title: Improvements in or relating to hydraulic presses and hydraulic rivetting machines
IPC: B21J15/20
Filed: 1939-07-27
Abstract: 532,883. Hydraulic presses. BRADBURY & SONS, Ltd., J., and POWELL, V. July 27, 1939, No. 21899. [Class 69 (ii)] A hydraulic press, which may be applied to riveting operations, is constructed with a piston 11 which is pressed into contact with the work by a plunger 10 in a cylinder 8 which is supplied with low pressure liquid from a pump 4 where a valve 6, Figs. 2 and 6, is operated to cut off the flow of liquid from a byepass tube 40 to direct it to the cylinder 8 via tubes 19, 21, and a passage 22. The tube 19 also leads to a cylinder 13 above the cylinder 8 and a piston 14 in the cylinder is moved to operate an intensifier plunger 17 when the tool attached to the piston 11 contacts with the work. The piston 11 is actuated against the action of weak springs 32, and the piston 14 is actuated against the action of stronger springs, and so the final heavier pressure is applied only after contact of the tool with the work. A pressure gauge 54 indicates the operating pressure. In a modification, Fig. 6, the piston 20 of the intensifier is arranged in a cylinder arranged at an angle to the cylinder 8, and the supply of liquid to the cylinder is controlled by a sliding piston valve 65 which transfers the supply of liquid from the cylinder 8 to cylinder 12 when the pressure in a chamber 62 is adequate to overcome the resistance of a spring 67. The intensifier plunger 17 passes through packing 47 making a liquid-tight connection where it enters the chamber 8. A spring-pressed valve may open to byepass the liquid when the pressure reaches a pre-determined valve, and an injector may be arranged in connection with the byepass circuit to assist the return of the operating liquid when the valve releases the operating pressure.

Title: Improvements relating to the manufacture of rubber-like substances
IPC: C08G63/91
Filed: 1945-08-27
Abstract: Highly polymerized esters of dialkylolarylamines of the general formula <FORM:0597783/IV/1> where R is an aromatic radical, with dicarboxylic acids of the series HOOC-(CH2)n-COOH, n and m being integers greater than 1 (see Specification 572,671) are incorporated with at least one substance selected from the group consisting of elements in Group II of the Periodic System and oxides, hydroxides, carbonates, borates and polymethylene dicarboxylates of such elements.  By allowing the mixture to stand for some time at ordinary or elevated temperatures a gradual improvement in physical and chemical properties may be observed, the esters being harder, tougher, having reduced tackiness, tendency to flow and solubility and a higher softening point.  Resistance to hydrolytic degradation is increased.  Incorporation may be effected by milling, masticating or by mixing the added substance with a solution of the ester and evaporating the solvent.  In the examples: (1) N-phenyldiethanolamine-adipate was prepared by heating the ingredients in presence of syringic acid in an atmosphere of dry oxygen-free nitrogen with subsequent addition of d-camphor-10-sulphonic acid and reduction of the pressure.  The product was compounded with 10 per cent of its weight of magnesium oxide on a rubber mill and allowed to stand 7 days; (2) the same product was compounded with 10 per cent calcium oxide; (3) N-p-tolyl-diethanolamine sebacate was compounded with 10 per cent magnesium oxide and left to stand for 48 days; (4) N-phenyl diethanolamine adipate was compounded with 35 per cent of beryllium carbonate; (5) the same ester was compounded with 10 per cent magnesium metal powder, kept 3 days at ordinary temperature and then for 20 hours at 100 DEG  C.  In a modification, 20 per cent of magnesium adipate replaced the metal powder; (6) N-phenyl-diethanolamine adipate was dissolved in tetrachlorethane and magnesium oxide was added.  The solution was spread and the solvent evaporated to yield a film.  In each case the improved properties of the product are noted.

Patent GB-827051-A (GB)
Title: Improvements in or relating to apparatus for feeding and presenting bags for filling
IPC: B65B43/30
Filed: 1955-07-29
Abstract: 827,051. Packaging-machines. AUTOPACK Ltd., and LEE, G. A. Oct. 29, 1956 [July 29, 1955], No. 22024/55. Class 94(1). [Also in Group XVI] In a filling machine, apparatus for removing flat bags, particularly plastic bags, from the base of a stack, opening them and presenting them to a filling nozzle includes a suction device for displacing the closed end of the lowermost bag, a separator blade for entering between the lowermost bag and those above to remove that bag from the stack, and suction devices for opening the bag mouth. The bags 33 are held in an angularly adjustable magazine 32 with loose separator plates 37 between batches to increase the magazine capacity. Pivoted at 41 is a platform 40 carrying suction cups 42, 43, and a carrier 62 for the separator blade 61, the latter being slidable along the carrier parallel to the base of the magazine by cam and lever means 65, 68. The forward end of the blade 61 has a suction opening, and the blade carrier a catch 38 which ejects the separators 37 during its rearward movement. The platform 40 is raised by cam and lever means 44-48 towards the magazine base lifting the carrier 62 with it. The suction cup 43 is movable relative to the platform by Bowden cable means, Fig. 4 (not shown), to engage the lowermost bag and pull its closed end downwards whereupon the blade 61 is advanced to separate that bag from those above. The platform 40 is lowered, the carrier, blade and bag moving with it until the carrier is arrested by a stop. The platform continues to move downwards and, as the bag walls adjacent the mouth are engaged by the cup 42 on one side and the suction aperture in the blade 61 on the other, the bag mouth is opened. Separation of the bag walls from each other may be assisted by movement of the cup 42 longitudinally of the platform 40, it being mounted on a slider engageable by a fixed surface during downwards movement of the platform. Arms 80 carry blades 81 which enter, stretch and grip the opened bag mouth and swing the bag onto the filling nozzle of a weighing and filling means 14, 15 (not detailed). The arms 80 are slidable on a shaft 83 towards and away from each other by cam and lever means 84-88 and are raisable through 90 degrees by a member 91, 92 fixed to the shaft 83 which is part rotated by cam means. The blades 81 enter a bag in their adjacent condition and the arms 80 move apart causing them to grip the bag. If no bag is present, the arms move beyond their normal limit so that a switch is contacted to stop the weighing and filling means. As the latter initiates operation of the bag feeding means after each filling through a solenoid disengaging a brake, Fig. 3 (not shown), bag feeding also ceases. Filled bags are discharged by movement of the arms 80 towards each other, permitting the bags to fall onto a conveyer &c. During filling the arms 80 may be agitated by the cam means normally operative to swing them up and down, thus settling the article packaged. Specification 827,052 is referred to.

Abstract: 715,129. Machines with permanent magnets. TELEPHONE MANUFACTURING CO., Ltd. July 21, 1952 [Sept. 20, 1951], No. 22063/51. Class 35 A hand-driven tone generator has a polarized rotor 12 driven through a lostmotion device 15 which operates contacts 20, and friction device having a predetermined resistance opposing the rotation of the rotor. The friction device consists of a spring 22 mounted in an annular space between the rotor and the shaft 13 and this spring makes frictional engagement with a rotor bush 21 and a washer 23 resting against the front bearing 9. A driving shaft 14 is coupled by the lost-motion device 15 to a gear wheel 16 which meshes with a smaller pinion 17 secured on the rotor shaft - 13. The object of the friction device is to ensure that the required driving torque is always positive with respect to the rotor, i.e. the rotor is not allowed to " run away" due to its inertia even when the operator is bringing the driving handle to rest and so contact chatter does not occur. Specifications 672,140, 672,202, [Group XXXVII]. 705,187 and 715,165 are referred to.
