Title: Delivery device for paper sheets and the like
Inventor: ONOMOTO RIYUUICHI
IPC: B65H3/06
Filed: 1988-07-15
Abstract: PURPOSE:To ensure the proper delivery of each one of paper sheets and the like by providing a pickup roller for receiving the paper sheets and the like while keeping a constant interval between the external surface of a delivery roller and the leading edge of the paper sheets and the like. CONSTITUTION:Notes 11 are pulled in a delivery direction with the delivery turning force of a delivery roller 17. Then, the notes 11 are delivered one by one to a succeeding stage under a separation effect due to the overlap of the rough surfaces of a separation roller 18 and a friction roller 10 opposite thereto. In this case, a pickup roller 16 is located coaxially with the delivery roller 17 and receives the leading edge of the note 11, thereby allowing the delivery thereof with a constant opposite gap kept between the delivery roller 17 and the leading edge of the notes 11. Consequently, a delivery member 21 comes in contact with the leading edge from a position off by the predetermined distance during a delivery process, or comes in contact with the leading edge at a constant delivery pressure. An optimum feed amount, therefore, is available simply by providing the pickup roller 16.

Title: Method for adding coolant into tundish
Inventor: UCHINO TSUNEO
IPC: B22D11/118
Filed: 1985-08-15
Abstract: PURPOSE:To improve the solubility of a coolant and to maintain a uniform temp. of a molten steel after cooling by delineating a segmented pouring chamber into a tundish by a partition gate bored with a pouring hole and dissolving a coolant by the high-velocity flow formed by the pouring hole. CONSTITUTION:The tundish is partitioned by the partition gate 2 bored with the pouring hole 1 to provide the segmented pouring chamber. The size of the hole 1 is so determined that the molten steel flows at 20-40m/min flow rate in order to maximize the solubility of the coolant 6 and to improve the floating effect of inclusions. An undercut 3 is preliminarily provided to the gate 2 to prevent the stagnation of the molten steel in the segmented pouring chamber at the end of the casting. The molten steel poured through a pouring hole 5 of a nozzle 4 into the segmented pouring chamber is increased in the flow rate by the vena contracta around the coolant 6 added thereto just before the hole 1 to increase the dissolving speed of the coolant 6. The steel past the gate 2 diffuses to the uniform flow and is tapped from a tap hole 7 into a casting mold. The control of a wide temp. range is thereby made possible by the simple device.
