Title: Improvements in and connected with furnace installations for ships
IPC: B63G13/02
Filed: 1928-09-07
Abstract: 322,521. Hammond, C. F., and Shackleton, W. Sept. 7, 1928. Smoke, discharging.-In a steam generator installation for ships, pulverized fuel and air are supplied under pressure to the closed combustion chamber f of the boiler b and the waste gases are conducted from the smoke box d through a U- shaped flue c extending above the water line and discharging through transverse vents e<1> in the ship's bottom. Distribution of the gases over the bottom of the ship to reduce skin friction, is effected by longitudinal fins which also prevent the gases escaping laterally to the water level. A portion of the combustion products is led through a pipe j to the fuel bunkers to aerate the fuel and facilitate its conveyance to the burners and prevent spontaneous combustion. A funnel h controlled by a damper i may be employed if desired. Fig. 3 shows a modification in which the gases pass from the boiler to a flue @ arranged above the water line and discharging through pipes e<2> and outlets e<3>.

Title: A shock absorber
Inventor: CHANO TASASHI
IPC: F16F9/512
Filed: 1963-07-01
Abstract: 1,048,072. Shock absorbers. KAYABA INDUSTRY CO. Ltd. July 1, 1963, No. 26028/63. Heading F2S. In a telescopic shockabsorber in which the damping force is smaller for high frequency vibrations, e.g. over the secondary resonance curve QR, Fig. 2 (not shown), due to the unsprung weight such as UW, Fig. 1 (not shown), for a wheel of a vehicle suspension system, a piston 5, carried by a rod 2 and working in a cylinder, has throughpassages 3, 4 controlled respectively by spring- loaded valves 8, 9 for checking the flow of hydraulic fluid from the upper to the lower and from the lower to the upper sides of the piston 5 respectively during rebound and compression strokes. During a rebound stroke the pressure developed in the upper chambers A of the passages 4 is also applied to the chambers B on the lower side of the leaf valve 9 by means of an orifice 12 and a chamber C in the piston-rod 2, the base of the chamber C being closed by an inertia piston 13 slidably mounted in a piston nut 6 and urged upwardly by a spring 13. For high-frequency short timeconstant vibrations the feed-back flow resistance path 12, C is such that the pressure differential across the valve 9 is relatively large so that the opening of the valve 9 is correspondingly large and the damping is reduced. There is time to build up pressure on the reverse side of the valve 9 during low-frequency vibrations so that the pressure differential across the valve and consequently the valve opening, is small, the damping being considerably increased. The valve 9, clamped in the piston 5 by the piston nut 6, is urged upwardly to close the passage 4 by a sleeve 11 which is slidable over the piston nut 6 and is loaded by a spring 10, the valve 8 being pressed downwardly over the passages 3 by a spring 7. The pressure area of the upper pressure chamber A in a passage 4 against the valve 9 is slightly larger than that of the pressure area below the valve 9. In a modification, Fig. 4 (not shown), the chamber Ca, formed in a piston nut 6a, communicates with the lower pressure chamber B through passages Da, D6, communication with the upper pressure chamber A being afforded through an orifice 12a in the valve 9. The piston 13 can be replaced by a diaphragm or bellows or by any other suitable resilient body.
