Abstract: A running textile web that has been subjected to soaking by a liquid such as a scouring solvent is carried between a suction box located adjacent one face of the web and a source of pressurized and relatively dry heated gas adjacent the other face thereof and opposite the suction box. The heated gas passes through the web and is drawn into the suction box, enhancing the amount of liquid removed at this stage and presenting the web into a drying stage with less entrained liquid than if the web were subject to the action of the suction box only. The amount of mechanical mist is kept to a minimum within a closed scouring range by means of a closed loop between the suction box and a return conduit provided with a trap containing a batt of metallic wool. The liquid discharge from nozzles employed to uncurl the edges of the web is directed against shields also containing a batt of metallic wool to reduce bouncing, noise and mist generation.

Abstract: Visual indicia or patterns are produced as each of the successive increments extending across a continuously advancing web of paper or fabric is imprinted with a series of visual dots from a sheet or ribbon containing a visual medium by at least one closely packed series of elements that are selected instantly by electronic logic, energized simultaneously by electrical pulses, and recycled rapidly by a common electrical and thermal bus. Specified parameters have been found to combine rapid advancement of the web and close packing of the visual dots.

Abstract: A skylight system is provided for installation on a roof in such a manner to remain weather-tight over a wide range of temperatures. Transparent or translucent panels in aluminum frames are mounted to a steel roof of a building by suitable connectors. Upon a change in temperature, the aluminum frame will expand or contract at a rate different from that of the steel roof, causing relative displacement between the skylight and the roof. To allow for a weather-proof seal to be maintained between the skylight and the roof, a slip joint is provided by means of an aluminum flange fixed to the skylight frame and having an inwardly extending lip spaced above and parallel to the outer face of the skylight and a steel flashing having a U-shaped bend along its free edge slipped over the lip of the flange and at its opposite edge being attached to the roof.

Abstract: A bicycle lock comprised of a U-shaped shackle and a bolt lockable across the end of the shackle is detachably connected to a bracket mountable to the bicycle frame for storage purposes. The lock bolt is formed with a flat shank portion and an enlarged end portion. The shank portion passes through a pair of opposing slots formed at the ends of the shackle legs to engage a locking mechanism on one leg of the shackle. The enlarged end of the bolt prevents the bolt from passing through the shackle leg and also serves to engage the bracket. The bracket preferably is formed from two strips of metal bent and joined to define a pair of parallel leg sections with a pair of spaced apart semi-cylindrical portions one of which engages a part of the bicycle frame while the other engages the enlarged end of the bolt. Integral tab portions are formed on the free end of the bracket to extend through the shackle slot and against the shank of the bolt to hold the lock assembly in clamping engagement against the bracket.
