Title: Improvements relating to fans, compressors and the like
IPC: F04D29/34
Filed: 1952-04-30
Abstract: 700,898. Axial-flow fans and compressors. DEAN, G. A. April 30, 1952, No. 10899/52. Class 110 (3) In an impeller for an axial-flow fan or compressor, each blade has an enlarged root in the form of a section of a cylinder which is pivotally mounted in a correspondingly shaped socket in the periphery of the impeller hub, and a resilient material tending to resist pivotal movement is interposed between each blade and its socket. Impeller blades 11, Figs. 2, 3 and 4, which are preferably moulded of synthetic resin but may be of wood or metal, each have a semi-cylindrical root 14 which engages a correspondingly shaped recess 15 machined diagonally in the periphery of the hub 10. The hub is preferably of magnesium alloy. A resilient member 16, preferably of rubber or like material, is placed under the root 14 to dampen blade vibration. Around the stem of the blade is a filler band 17 of rubber or like material, preferably cemented to the blade. Longitudinal location of the blades in the recesses 15 is provided by retaining strips 18 in the form of arcuate segments of sheet phenolic fibre or other relatively flexible material which are inserted into grooves 19 at each side of the hub 10. The marginal walls of the grooves 19 are cut away at one place on the hub to provide a gap through which the retaining strips 18 can be successively inserted into the grooves. After the last strip has been inserted, all the strips are advanced slightly so that an intermediate part of one of them spans the gap. Between each blade and the strips 18 are individual spacers 21 and 22, the latter preferably being moulded of phenolic material to the contour of the recess 15 and the former being of resilient material such as rubber. The spacers 21 may be bonded either to the ends of the roots 14 or to the spacers 22. A grooved flange 23 on each spacer 22 is shaped to conform with the maginal wall of the adjacent groove 19. To balance the impeller, lightening holes 24 may be reamed to remove metal or plugged with cork; this must be done before the holes are covered by the strips 18. In the modification shown in Fig. 5, the dampening member and the filler band are formed as a single piece 25. In either embodiment, the stem of each blade 11 may be slightly offset with respect to the axis C of the root 14, as shown by dotted lines in Fig. 3, so that the turning moment due to centrifugal force balances that due to aerodynamic forces.

Patent GB-925465-A (GB)
Title: Improvements in or relating to the treatment of cellulosic material
IPC: D06M10/08
Filed: 1961-03-28
Abstract: Cellulosic material, particularly cellulosic textile material, is irradiated with accelerated electron beams (b -rays) having a particle energy of less than 1 MeV, and preferably 0,05-0,6 MeV, the material being heated during or after irradiation to induce cross-linking between cellulose molecules with consequent improvement in mechanical properties such as dimensional stability, and resistance to shrinking and abrasion.  Suitable radiation is conveniently derived from electron accelerators, or from radio-active sources, e.g. Sr90 or Kr85.  The total dosage of radiation, usually 103-107 rad. and preferably 104-106 rad. (1 roentgen=0,83 rads., approx.) is sufficient to effect the desired cross-linking while leaving the mechanical properties of the material unimpaired.  The cellulosic material may be topochemically modified, prior to irradiation, by compounds such as isopropylbenzoyl chloride, which promotes the formation of "active" groups as in the parent Specification.  The process may be applied to yarns, filaments, threads or woven, non-woven or knitted fabrics composed wholly or partly of natural cellulose, e.g. cotton or of regenerated cellulose, and also regenerated cellulose film and paper.  In the examples, bleached poplin, renforc<\>e cotton and bleached cotton voile are irradiated to a total dosage of 105-106 rads.  Heating of the irradiated material is effected by steam or warm air.
