Title: Apparatus for assembling gaskets in bottle caps and the like
IPC: B65D41/16
Filed: 1929-04-15
Abstract: 312,053. White Cap Co., (Assignees of White, W. P.). May 19, 1928, [Convention date]. Making capsules, stoppers, and packing- rings. -An apparatus for inserting elastic gaskets into closure caps &c. comprises a table 10 supporting a recessed base plate 11 having an integral sleeve 12 projecting from its lower side. A stub shaft 15 rotatably mounted in the sleeve 12 carries an actuating cross-arm 16. Pins 17 project upwardly from the ends of the arm 16 into arcuate slots 18<a> in a plate 18. The plate 18 is stationary and the upper ends of the pins 17 engage in holes in a rotatable ring 19. A covering plate 20 encloses a number of metal segments 21 assembled one above the other each having an anchor pin 22 which is rotatably secured in the plate 20, and a guide pin 24 which operates in a radial slot in the ring 19. This connection of each segment with the plate 20 and the ring 19 is made possible by the fact that the segments are in successively offset relationship. When the ring 19 is rotated in the direction of the arrow in Fig. 1 the lower ends of the segments swing inwardly decreasing the circumference of the area enclosed by them. The ring 19 is rotated by the shaft 15 which is operated by a treadle lever 25 pivoted at 26 and carrying a roller 28 mounted in a yoke 27. This roller co-operates with a lever 29 on the shaft. A coiled spring 31 draws the lever &c. to the position at which the segments are at their outward limit of movement and rearward pressure on the treadle brings the segments to their inner position. A mandrel 34 rests freely on the plate 18 over which a gasket G. is placed and constricted by the inwardly moving segments'. A cap C is then placed over the gasket and pushed down immediately the pressure of the segments is released. The cap and gasket is then removed and the operation repeated as necessary.

Title: Permanent deformation of human hair
IPC: A45D7/00
Filed: 1973-03-14
Abstract: 1416564 Treating human hair WELLA AG 14 March 1973 [21 March 1972] 12328/73 Heading D1P Human hair is permanently deformed by allowing a forming agent containing a water soluble mercapto carboxylic acid salt and a salt of glyoxylic acid to act on the hair, after which the hair is fixed by treatment with a fixing agent containing hydrogen peroxide or a compound of addition thereof, and without intermediate rinsing of the hair. 'The mercapto carboxylic acid salt used is preferably a water-soluble salt of thioglycolic acid or thiolactic acid. A salt of ascorbic acid may be added to the glyoxylic acid salt. The salts of glyoxylic acid and optionally ascorbic acid may be present in a total concentration of from 2 to 4% by weight based on the total weight of the agent. For the permanent waving of hair, the hair may be first moistened with a part of the forming agent and then wound on to permanent waving curlers, further moistened with the remainder of the forming agent and optionally covered with a hood-like plastic cloth. After an action time of 10-20 minutes, the curled hair is thoroughly moistened with part of the fixing agent which is left to act for 2-3 minutes. Then, after removing the hair from the curlers the remaining fixing agent is applied and left to act for a further one to three minutes. Finally the hair is rinsed with water and after-treated to produce the hair style. Permanent straightening of crinkly hair may be effected by applying the forming agent in a thickened formulation and allowing it to act for 10-20 minutes while combing the hair repeatedly. The hair is then treated for 3-7 minutes with a thickened formulation of the fixing agent, after which the hair is rinsed in water and after-treated to produce the hair style. Forming and fixing agents are exemplified which, on admixture, produce a temperature rise of up to 50C. Further heat may be supplied during the initial treatment of the hair e.g. by a hair dryer.

Title: Manufacture of molded sand articles such as foundry cores and dry sand molds
IPC: B22C9/14
Filed: 1920-05-04
Abstract: 142,833. Lane, H. M. Dec. 26, 1913, [Convention date]. Drying-kilns.-In baking or drying foundry sand cores or moulds by the use of hot gaseous products of combustion in an oven, the gases are mixed with cooling or other diluents, such as air or steam, to give the gases a suitable temperature or humidity for the form or composition of the cores &c. to be baked. When linseed oil is used as the core binder, the gases should be of an oxidizing character. The steam may be superheated or saturated, or may be formed by spraying water into the hot gases. This prevents damage, through excessive heating, to comparatively thin portions or edges of the core &c. In a suitable form of apparatus, the furnace 5 is arranged to burn coal, oil, gas, &c. and steam or air may be introduced by nozzles or pipes 19, 22. 23a, 35, either before or after the gases pass through the fire, or at suitable positions in the flues. In some cases, especially when volatile combustible gases are given off by the cores during drying, a portion of the gases exhausted by pipes 26, 27, from the oven 2 may be delivered by a fan 32 to nozzles below the furnace 5, the remainder being exhausted through to the stack 31, preferably by a fan as shown.

[Classes '51 (i) and 51 (ii)] A crucible, muffle or like furnace heated by solid fuel is supplied with air for combustion by nozzles which project into the combustion chamber from the boundary wall so that the zone of maximum temperature is in close proximity to the crucible or other container to be heated. Fig. 1 shows a crucible furnace in which the air for combustion is heated in pipes 17, 18 arranged in the flue between the casing 16 and fuel hopper 29 and is then led through helical passages in upper and lower compartments 7, 8 between the walls 3, 4 before being delivered through the nozzles 11 into the fuel. The casing 16 is mounted on a shaft 26 upon which it may be raised and swung aside to provide access to the combustion chamber. The temperature within the crucible 15 may be measured by an optical pyrometer sighted through tubes 32, 33 provided with a reflecting prism 34. The tube 32 and a tube 35 for supplying hydrogen or other -gas to the crucible are enclosed in a water jacket 36. Fig. 2 shows a continuous furnace in which the charge is fed from a hopper 51 into an externally heated shaft 47 formed in sections 48 with a sectional lining 60. The charge is removed by a device 56. The lower part of the shaft fits a cylindrical extension 49 of the combustion chamber and rests upon a ring 50. When the section of the shaft adjacent the blast nozzles 46 needs renewing, a fresh section is inserted from below and the top section is removed. Blast is heated in a coil 45 and then passes to the annular space 44 and nozzles 46 which may be protected by removable saddles 66. The nozzles are removable and may be formed of zirconium silicate, of which the saddles may also be made. Fig. 3 shows a domed muffle 77 arranged within the combustion chamber 75 and provided with charging and discharging passages 78, 80 extending through the walls of the furnace. Air is supplied to the nozzles 76 by a main 81 communicating with the helical passage 74. Hydrogen or other gas may be supplied to the muffle by a pipe 86. The shaft 47 shown in Fig. 2 may be replaced by superposed crucibles, the lower most one of which may be removed periodically and the remaining crucibles lowered for the insertion of a freshly charged crucible at the top. Instead of the shaft 47 being arranged vertically it may be inclined or horizontal. Specification 492,394, [Group V], is referred to.
