Title: Improvements in or relating to the manufacture of phosphors and fluorescent lamps
Inventor: MCKEAG ALFRED HAMILTON
IPC: C09K11/76
Filed: 1958-07-30
Abstract: A method of manufacturing a crystalline inorganic phosphor powder, in which substantially all the particles are of sizes between 25 and 5 microns, comprises crushing the sintered mass formed by firing the component materials of the phosphor to form an intermediate powder consisting substantially of particles of sizes less than 25 microns and containing a major proportion of particles of sizes in the range of 25-5 microns and an appreciable proportion of particles of sizes less than 5 microns, suspending the intermediate powder in a liquid, e.g. distilled water, and causing the suspension to flow under pressure through a cyclone in which a rapidly spiralling motion of the suspension takes place, resulting in a major proportion of the particles which are greater than 5 microns being thrown to the walls of the cyclone and falling to the apex from which they are withdrawn, and a major proportion of the particles which are smaller than 5 microns being drawn into a rising vortex and passing out through the vortex finder at the top of the cyclone.  The fractions emerging from the cyclone can be passed through one or more further cyclones in which further separation takes place.  In a preferred embodiment the sintered mass is lightly crushed to include also an appreciable proportion of particles greater than 25 microns and the intermediate powder, or a powder derived therefrom by passing through a meshed sieve, is suspended in the liquid and caused to flow under pressure through a first cyclone in which particles greater than 25 microns are withdrawn and the remainder pass to a second cyclone in which separation as above described takes place.  Additional cyclones can be employed.  In this embodiment the intermediate powder can be passed through a mesh sieve which retains particles greater than 60 microns, the sieved powder containing about 15% by weight of particles of sizes in the range of 25-60 microns with the mode of size/weight distribution at about 14 microns.  Apparatus for performing the method is described and dimensions of the cyclones are stated. Specification 578,192 also is referred to.

IPC: D01C3/00
Filed: 1924-08-25
Abstract: 235,050. Ehrenreich, A., and Bendixen, R. Aug. 25, 1924. Fibres, obtaining.-Fibres are obtained from the skins of chondropterygians and plagiostomes or from the waste of tanned skins thereof. Long silk-like threads of great tensile strength and having high water-resisting qualities are obtained. The prickles or horn plates are first removed by known treatment with dilute acids. The skins are then swelled with dilute sodium sulphide solution and reduced to fibres by a tool faced with needles. To make the fibres durable either the skins or the fibres are treated with an extract from the gastric juice and/or urine of the fish from which the skin is obtained, or by other preserving treatment, and the fibres are baled for transit. By grinding the fibres and mixing with a suitable cement such as glue obtained from chondropterygians and plagiostomes the product may be used as insulating means for electricity, heat, and moisture, and, with the addition of formaldehyde and the application of great pressure, a hard material suitable for gramophone discs and the like, is obtained.
