Title: Axial flow blower of high energy transfer - has rotating blades of various angular distribution and separation
Inventor: YAMAGUCHI NOBUYUKI
IPC: F04D29/32
Filed: 1975-05-30
Abstract: An axial flow blower has several blades (3, 4) which are separated from each other to varying degrees, and which have profiles of unequal sequence to produce higher energy in the flow which passes the blades in a narrow blade channel, so that an almost equivalent energy output into the blast flow is generated to the energy input to rotate the blades. The blades may be plates of similar shape but with different angles of inclination to each other. This arrangement avoids hydraulic loss and thereby improves the efficiency of the blower. The total noise level can be reduced by matching the number of blades with the revolutions.

Title: Redistribution nozzle for reflux water coolers - with conical slotted plate below orifice, giving improved wetting
Inventor: WOEHLER HANS-JOACHIM
IPC: F28F25/06
Filed: 1975-07-24
Abstract: A redistribution nozzle for reflux water coolers has a plate fitted below the orifice, this plate having a conical surface and flow passages. The distance between the orifice and the plate is small, and the flow passages are slots, open at the edge of the plate, following secants, in pairs which are parallel to one another but of different lengths. In alternative forms, there is a second plate, below the first, flat or conical, with slots staggered in relation to those in the first, wedge shaped and narrower at the edges of the plates. The plate is carried on one or more rods fixed to a tube which surrounds the nozzle. Alternatively, the support may be a cage, made of several arms, in which the rod carrying the plate fits. The nozzle gives more uniform distribution than existing devices, because wetting takes place not only on an annular surface around the orifice but also in the central circular part. The wetted area is maintained constant in spite of flow variations.
