Abstract: A car safety seat includes a seat body, at least one knob and at least one safety belt. The seat body has at least one slot structure. The slot structure includes a plurality of first positioning slots and a plurality of guiding slots. Each of the first positioning slots is connected with another adjacent one of the first positioning slots through one of the guiding slots. The knob is movably disposed on the seat body and has a second positioning slot. The safety belt penetrates through the second positioning slot and the corresponding first positioning slot in sequence. The knob is adapted to rotate to drive the safety belt to enter the corresponding guiding slot, and the knob is adapted to move along the slot structure to drive the safety belt to pass through the guiding slot to arrive another adjacent one of the first positioning slots.

Abstract: A car safety seat includes a seat body and at least one safety belt. The seat body has at least one slot structure, wherein the slot structure includes a plurality of positioning slots and a plurality of guiding slots. The positioning slots are arranged with intervals in sequence, wherein each of the positioning slots has a first section and a second section opposite to each other. Each of the positioning slots is connected with another adjacent one of the positioning slots through one of the guiding slots, and each of the guiding slots extends from the first section of one of the positioning slots to the second section of another adjacent one of the positioning slots. The safety belt penetrates through any one of the positioning slots, wherein the safety belt is adapted to move along the corresponding guiding slot to reach another adjacent one of the positioning slots.

Abstract: An adjustable footrest assembly adapted to a car safety seat is provided. The car safety seat includes a seat body. The adjustable footrest assembly includes a footrest and two flexible connection structures. The two flexible connection structures are connected to two ends of the footrest. The footrest is adapted to be connected to the seat body through the two flexible connection structures, and a length of each of the flexible connection structures is adapted to be adjusted to change a distance between the footrest and the seat body. In addition, a car safety seat having the adjustable footrest assembly is also provided.

Abstract: The invention relates to a thermal conversion process for continuously producing hydrocarbon vapor and continuously removing a free-flowing coke. The coke, such as a shot coke, can be withdrawn continuously via, e.g., a staged lock hopper system.

Abstract: Described herein are methods and mechanisms for laterally dispensing fluid to a coke drum in a predictable and maintainable manner that alleviates thermal stress. In one embodiment, the methods and mechanisms utilize a split piping system to dispense fluid through two or more inlets into a spool that is connected to a coke drum and a coke drum bottom deheader valve. A combination of block valves and clean out ports provides a more effective means to clean the lines and allows fluid to be laterally dispensed in a controllable and predictable manner. The fluid is preferably introduced to the spool in opposing directions toward a central vertical axis of the spool at equal but opposing angles ranging from minus thirty (?30) to thirty (30) degrees relative to a horizontal line laterally bisecting the spool. Alternatively, however, fluid can be introduced to the spool tangentially.

Abstract: A method for producing and removing coke which has bulk morphology such that at least about 30 volume percent is free-flowing under the force of gravity or hydrostatic forces from a delayed coker drum. At the completion of the fill cycle, the coker drum, filled with hot coke, is cooled by steaming and then flooding it with water, thereby producing a coke/water mixture. The coke/water mixture is released from the coke drum through one or more drum closure/discharge throttling systems near the bottom of the coker drum.

Abstract: One embodiment of the present invention is an insulated curved metal pipe characterized by a curved body of a given length having a first section, a central section and an end section. The body has a monolithic refractory lining extending for the length of the body which is in contact with the internal surface of the first section and second section and which is spaced apart from the internal surface of the central section by a flexible insulating material, whereby the insulated curved pipe has greater flexibility (i.e., less stiffness) than otherwise possible when the cast refractory is in contact with the internal surface of the entire curved body. The curved pipe also includes a plurality of anchors attached to the internal surface of the curved body. Importantly, the anchors in the central section are sufficiently flexible to permit at least some deformation of the central section of the body relative to the refractory.

Abstract: In brief, a grid plate, especially a flat grid plate, horizontally disposed in a fluidized solids contacting vessel, is supported by a conical skirt that extends downwardly and inwardly from substantially the outer periphery of the grid plate for a predetermined portion of the length of the skirt and then downwardly to the bottom of the vessel. Preferably, the conical skirt extends inwardly at an angle, .alpha., measured from the vertical in the range of about 20 degrees to about 45 degrees, and preferably about 30 degrees, for a distance equal to about one third to one half of the length of the skirt, and generally for a distance of about half the length of the skirt.
