Filed: 1946-10-10
Abstract: 617,826. Infusing-machines. NOWAKOWSKI, M. K. Oct. 10, 1946, No. 30237. [Class 129] The water is boiled in an outer vessel and is transferred to an inner vessel enclosing a perforated container for the tea or other herb by way of a pipe or channel on the outer surface of the inner vessel ; the pipe is open at a point slightly above the bottom of the inner vessel and closed at the top and gives access to the inner vessel by way of a hole located above the contemplated level of the infusion. Two diametrically opposite pipes are each comprised by a U-shaped channel 17 soldered to the surface of the inner vessel 2 and opening into it through a hole 18. The boiling water is forced by steam pressure up each pipe and on to the tea in a perforated basket 15. When infusion is completed, the basket is removed, enabling a float 13 to rise to the surface of the liquid to seal it against contact with the atmosphere. The side walls of the float are curved in the vertical plane to prevent jamming if the float tilts. The outer vessel is filled through a funnel 9 having a cap 10 secured by a bayonet connection 11 ; in addition, a direct connection may be made from the water mains to the bottom of the outer vessel. Specifications 569,124 and 589,366 are referred to.

Filed: 1935-11-01
Abstract: 454,189. Enamels and glazes; glass manufacture. DEUTSCHE TAFELGLAS AKT.-GES. (DETAG), 21, N³rnberger, F³rth, Germany. Nov. 1, 1935, No. 30243. Convention date, Nov. 5, 1934. [Class 56] A process for improving the resistance of glass, enamel, or glaze to chemical attack consists in incorporating water vapour'with the material while in the molten state, and preventing the escape of the water so incorporated during subsequent treatment. This is effected either by producing above the molten mass an atmosphere containing water vapour, or by introducing substances containing water into the molten mass or into the batch. Suitable substances for the latter purpose are moist sand, soda containing water, moist briquettes of glass, moist wood, or pieces of potato. The water vapour is prevented from escaping from the molten mass by maintaining above it an atmosphere containing water, for example, by introducing the vapour into a covered pot in which the batch is melted.

[Also in Groups XXXV and XXXVI] A solid electrical conductor or group of solid electrical conductors, e.g. a dynamoelectric machine armature bar, is insulated by a method in which a tube of silicone rubber or other electrically insulating material having similar elastic properties is collapsed on to the conductor(s) after expansion by air pressure only, by applying over one end of the conductor(s) the end of the tube remote from that connected to an air pressure source, controlling the air leakage from the tube whilst moving the remote end thereof along the conductor(s), and then releasing the air pressure so that the tube immediately contracts down on to the conductor(s). The leakage may be controlled by finger pressure or a short tubular member slidable along the conductors, the tube movement may be eased by a compatible lubricant e.g. silicone rubber paste, and the tube expansion may be limited by an enclosing sleeve. The insulation may be mechanically protected by a lapped tape of, e.g., glass reinforced silicone rubber, fused to the tube.

Abstract: 1,075,982. Relaxing filamentary material. AMERICAN CYANAMID CO. March 3, 1965 [Aug. 17, 1964], No. 30899/66. Divided out of 1,075,981. Heading B5B. [Also in Division D1] Apparatus for continuously relaxing endless lengths of a synthetic or artificial filamentary material comprises an elongate chamber having an opening at each end for passage through the chamber of the filamentary material, means for feeding endless lengths of filamentary material through the chamber, inlet means for introducing hot gas at high velocity into the chamber through an inlet at one end of the chamber, and baffle means for suitably directing hot gas entering the chamber. The baffle means comprises a tubular member disposed coaxially within the chamber and defining with the chamber an annular passage for hot gas entering the chamber through the gas inlet, the bore of the tubular member providing for passage of the filamentary material into or out of the chamber, and a number of open-ended tubes of short length and small diameter disposed in a ring within the annular passage adjacent, but downstream of, the gas inlet. As illustrated in Fig. 1, filamentary material, for example a tow 13, is passed by inlet rollers 15 and outlet rollers 16 through elongated chamber 11 which is in the form of a tube of circular cross-section and which has a gas inlet and a gas outlet at opposite ends thereof; conduits 20 and 21, which include blower 18 to impart the required velocity to the gas and heater 19 to heat the gas, connect the gas outlet to the gas inlet to provide recirculation of the gas. As illustrated in Fig. 3, the end of the chamber adjacent the gas inlet 40 is closed by closure plate 24 which has central opening 23 and from which extends tubular baffle member 25; a number of open-ended baffle tubes 26 are disposed in a ring within the annular passage formed between the elongated chamber and the tubular baffle member. A baffle plate 28 provided with a small orifice 29 may be disposed across the chamber downstream of the tubular baffle member. As illustrated in Fig. 2 (not shown), the end of the chamber adjacent the gas outlet also has a baffle arrangement but comprising only a depending tubular member analogous to tubular baffle member 25; however, if desired, a ring of open-ended tubes analogous to open-ended baffle tubes 26 may be provided. Each end of the chamber is closed by a cover-plate 35 which has a central slot 36 for passage of the filamentary material and which is secured to the closure plate by bolts 38 passing through slots 37. The chamber may be disposed with its longitudinal axis either vertical or other than vertical, for example horizontal; the hot gas and filamentary material may be in either cocurrent or countercurrent contact, the filamentary material moving either upwardly or downwardly through the chamber. It is preferred for the chamber to be vertical and for both the hot gas and the filamentary material to move upwardly in cocurrent contact; such relaxing treatment is described more fully in Specification 1,075,981.
