Title: Petroleum combustion device
Inventor: KAWASAKI YOSHITAKA
IPC: F23D3/10
Filed: 1985-07-08
Abstract: PURPOSE:To prevent both vertical and horizontal deformation and bending of a linear combustion device, secure complete burning, and also maintain uniform heating at a red hot part by installing vertical ribs at the upper part and horizontal ribs at the lower part in a plane part of a flat combustion chamber. CONSTITUTION:When thermal expansion occurs on wall surfaces of a flat combustion chamber 17 in accordance with their wall temp., expansion quantity is absorbed by elasticity of the ribs owing to the installation of vertical ribs and groove width is only changed and therefore, outward width of the combustion chamber 17 is kept at about the same size. And, as at the middle and lower parts of the combustion chamber, horizontal ribs which are used as reinforcing members to prevent bending of walls of the combustion chamber 17 are placed, bending of the combustion chamber 17 inward and outward in horizontal direction is avoided. At the same time, temp. difference between up and down directions, upward and downward bending of the lower end of the combustion chamber 17 is prevented by the ribs 21 and between a burner plate 16 and the lower end of the combustion chamber 17, gap is not formed and said two parts are closely contacted with horizontality. Therefore, in the combustion chamber 17, uneven flow of fuel and air is prevented.

Abstract: PURPOSE: To provide a coil material suited for blanking and improve the yield at the working by dividing a broad coil to widths of predetermined shapes and coiling the same.  
     CONSTITUTION: When a broad coil material 1 is fed to a press 3 by means of roll feed 2, it is slit continuously to coil materials (a)W(f), which are then divided to two groups at every other row by means of guides 5, 6. The coil materials (a), (c), (e) guided by the guide 5 form a loop 7 and are taken up on a recoiler 9 via a tension roller 8. The coil materials (b), (d), (f) guided by the guide 6 form a loop 10 and are taken up on a recoiler 12 via a tension roller 11. When the tail end of the broad coil 1 passes the roll feed 2, the coil 1 remains in the press 3 without being fed. Thence, the tail end of the coil material 1 is cut by a shear 4. The cut part of the tail end of the coil 1 becomes the tail end of each coil material (a)W(f) and reaches the recoilers 9, 12, and this ends the work.
