Title: Improvements relating to the manufacture of filaments for electric lamps
IPC: H01K3/04
Filed: 1929-12-20
Abstract: 339,803. Westinghouse Lamp Co., (Assignees of Wadsten, S., and Hunt, C. W.). Dec. 29, 1928, [Convention date]. Filaments.-A coiled filament for an incandescent lamp is made by coiling a wire in a machine such as is described in Specification 292,743, [Class 83 (iv), Metals, Working], or otherwise to a closer pitch than that finally required, cutting off a portion containing the required amount of wire, stretching it to the required overall length, and finally cleaning it. For this purpose the wire is fed by rolls 12, 13 to a die shaped so as to coil the wire to the desired pitch. The die 10 may be formed with a lip to space the coils, or when a very tight-wound coil is to be formed the lip may be dispensed with. When a predetermined length of wire has passed through the machine the wire is cut and the cut-off portion gripped between jaws 22, 23, Fig. 3. These jaws are then moved apart so as to space the coils to the desired extent, e.g. a coil with 390 turns per inch may be stretched so as to have 370 per inch. The jaws with the coil are then moved into a chamber containing neutral or reducing gas, where the coil is heated by a current passed through it by means of the jaws to destroy grease &c. on it and to give it a permanent set.. The coil may be heated in air before passing to the chamber containing the gas. It is stated that the end portions held by the jaws 22, 23 are heated less strongly than the remainder, and are therefore more pliable, which is of advantage in fixing the coil in the lamp.

Title: Improved method and apparatus for continuously heattreating products in sealed containers
IPC: A23L3/04
Filed: 1964-09-28
Abstract: 1,086,004. Heat-treating food &C in containers. P. CARVALLO. Sept. 28, 1964 [Oct. 1, 1963; Dec. 16, 1963; April 14, 1964], No. 39380/64. Heading A2D. Products such as foods and beverages in sealed containers such as cans, glass jars or aluminium vessels are continuously heat treated in at least one chamber containing treating liquid at the required temperature and maintained at an overpressure by a gas, whose pressure is maintained constant by at least one liquid-containing column through which the containers continuously enter into and emerge from the heattreating chamber. The liquid in the heating chamber is brought into contact with the containers by spraying, streaming, or by immersion. Several forms of the apparatus are described, each having a treating chamber through which the containers are moved by a conveyer and wherein the containers are subject to the action of hot sprays or mist and pressure due to the introduction of compressed air, the pressure being balanced by a corresponding height of hydrostatic column. As shown in Fig. 9, endless conveyer 2 carries containers down through entry water column 1, through treating chamber 5 where they are subjected to the action of jets 63 supplied by pump 60, with enough force to agitate the containers if desired, then out through exit water column 12. Compressed air is introduced at 33 under pressure sufficient to keep the water level in the treatment chamber at the level of the bottom edge 34 of one wall of the entry column. Any excess air bubbles up entry column 1 and escapes to atmosphere. In a modification, Fig. 6 (not shown), an arrangement is described for provided double columns for entry and for exit, whereby the physical height of the columns is halved. In other modifications, arrangements are described for maintaining pressures and water levels constant, notwithstanding the passage of large or small containers, by means of float-controlled valves.
