Title: Ship's propeller mounted in duct - has guide vanes of varying size angle and spacing and with ring for fixing
Inventor: SCHNEEKLUTH HERBERT PROF DR IN
IPC: B63H5/14
Filed: 1976-02-18
Abstract: The ship's propeller mounted in a duct with guide vanes is basically a Kort nozzle type assembly (1, 2), but 3 or more guide vanes (4) are fitted into the convergent part of the nozzle. The vanes are triangular, with their base (6) conforming broadly to the nozzle profile, but their inclination to the axis, size and spacing may vary around the periphery in the interest of optimising the water flow. They are all set to swirl the water in opposition to the propeller. A narrow notched ring may be fitted into the nozzle, to hold the trailing apices of the guide vanes in position. Such a ring will also improve the performance of the propeller when running astern. This also deflects any solid objects entrained in the water away from the propeller tips, reducing the risk of damage.

Title: Burner with noise suppressor - has passageways with sound absorbent lining for multiple reflection
Inventor: BITTERLICH GORDON M
IPC: F23C1/08
Filed: 1977-04-19
Abstract: The combination oil and gas burner is designed for suppressing the noise accompanying the entrance of the air for combustion and the combustion noise. Noise of low frequency inside the furnace produced by combustion upon attempting to exit through the muffle block (14) has no direct path for outward transmission but impinges on the exposed surface of the lining (60) in the housing (20) which has an absorbing effect. Any noise striking the burner block (36) is reflected to the lining. The outward path of noise, due to the arrangement of the passageways (78, 77 and 76) with their lining (60) is such that multiple reflection by the impact of the sound waves on the walls (60, 71, 72, 73) and the exposed surfaces of the burner block (36) the tubular frame (32) and outer frame plate (22) and the closure plate (23) occurs with attenuation in the linings.
