Title: Burner for combusting pulverized coal
Inventor: DEWA KOU
IPC: F23D1/02
Filed: 1979-09-20
Abstract: PURPOSE: To reduce the amount of NO x  generated by combustion of pulverized coal remarkably, by selecting the swirl angle of a swirler to be 25W35°, providing a flame retaining plate at the top of a primary throat, and designing a secondary throat to be movable in backward and forward directions.  
     CONSTITUTION: The swirl angle of a swirler 2 is selected to be 25W35°, and a flame retaining plate 7 diverged outwards is provided at the top of a primary throat 1. Around the primary throat 1 on the outside thereof, there is provided a secondary throat 3 coaxially with the primary throat 1 in the manner that it can be moved back and forth. With such an arrangement, pulverized coal ejected from the primary throat 1 is prevented from being scattered widely and it is combusted slowly at a low temperature because of shortage of O 2 . On the other hand, since secondary air issued from secondary throat 3 flows outwards, mixing of the same with pulverized coal in the primary flame zone can be hindered. Further, since the secondary and tertiary air flow can be controlled by moving secondary throat 3 back and forth, it is enabled to reduce the amount of NO x  produced by combustion of pulverized coal considerably.

Title: Piston brake
Inventor: SAWARA TAKASHI
IPC: F16F9/00
Filed: 1979-09-20
Abstract: PURPOSE: To brake a piston without shock sound and vibration accompanying the shock by a method wherein a pressure gas is distributed to the piston from its downward side at the end of the piston stroke when allowing the piston to stand still at the end of driving stroke.  
     CONSTITUTION: A main piston 3 quickly drops under the influence of the pressure of compressed air introducted into an upper chamber 2a, and the compressed air in the upper chamber 2a is led to a store-chamber 6 via a through hole 15 when the piston 3 has passed the air through hole 15. The compressed air introduced into the store-chamber 6 pushes down a valve piston for brake and control use resisting a compressing coil spring 13. A through hole 12 for a high pressure gas permits a high pressure gas passage 14 to come in contact with a lower chamber 2b, so that the high pressure gas is distributed as a strong back pressure to the lower chamber 2b, or the downward side of the piston 3. Thus, it is possible to prevent the piston 3 from smashing into the lower end 16 of a piston 2 and let the piston 3 stand still at the bottom dead point.
