Patent CA-2124623-A1 (CA)
Inventor: DUNCAN RICHARD N
IPC: D01G15/80
Filed: 1994-05-30
Abstract: Abstract An improved carding process utilizing a brush attached to a cylinder carding machine for inhibiting the buildup of napped fibers.         Mounted just downstream of the transfer region between cylinders where carding takes place, the brush is stationary with respect to the revolving cylinders.  The brush is disposed across the face of the carding drum, with the nylon bristles of the brush engaged in the card-cloth wires of the drum.  The bristles continuously brush, straighten and force napped fibers down into the wires of the carding cylinder, which results in a thicker, heavier web of carded fibers and virtually eliminates buildup of fluffy fibers on the carding drum as well as the input drum.

Title: Direct & continuous bath cooling system for continuous casting
Inventor: ELSAWY ABDEL RAOUF
IPC: B22D11/124
Filed: 1995-09-20
Abstract: This invention is a cooling system for the continuous casting. It is a simple as a cooling is achieved by a direct and continuous contact of a cast hot surface with a bath of a cooling fluid flowing into a cooling chamber through a cooling fluid inlet tube and departing through a cooling fluid outlet tube. This cooling system is a self-operating as a vacuum is created inside the cooling chamber by the presence of a fluid head pressure at the cooling fluid outlet tube. In the horizontal casting, the cast travels along the horizontal axis of a longitudinal cooling chamber and through a cast entrance and exit means of perforated flat ends. Said created vacuum introduces streams of ambient air into the cooling chamber through offset clearances surrounding the cast surfaces at the cast entrance and exit, and results in preventing cooling fluid leakages outward, redirecting erupted vapors inward and improving cooling by forming a turbulent cooling fluid flow around the cast surfaces. This turbulent flow can be further enhanced by means of inclined tube-jets positioned into the cooling chamber at the cast entrance end. The cooling fluid inlet and outlet tubes are joined with the cooling chamber at the lower portion near the cast exit end, and at the side top portion near the other end, respectively. The joint-connection of the cooling fluid outlet tube with the cooling chamber is positioned, so that it becomes partially immersed in the departing cooling fluid. Thus, air and erupted vapour removal out of the coating chamber, is achieved in form of bubbles entrained at the cooling fluid outlet tube, maintaining the created vacuum at a constant level. In the vertical continuous casting, the same embodiments are used with the cooling chamber positioned vertically and soft seal discs added at the offset clearance. Further, an auxiliary suction pump may be attached to the outlet tube.   In Olmo Continuous Casting, where other cooling systems impose limitations such as water leakages and vapor eruption, this cooling system has proven to be a viable option at cost effective with a compatible cooling rate".
