Patent GB-1007440-A (GB)
Title: A flow apparatus for separating granular materials
IPC: B07B7/08
Filed: 1962-05-14
Abstract: 1,007,440. Centrifugal separators ; beater mills. ALPHINE A. G. MASCHINENFABRIK UND EISENGIESSEREI. May 14, 1962 [July 7, 1961], No. 18369/62. Addition to 998,461. Headings B2A and B2P. Granular material is separated into particles of different sizes by means of an apparatus comprising a centrifugal-type separator wheel 27 in which a carrier medium, e.g. air or water, flows along substantially radially directed separating channels of cascade-shape formation, the carrier medium and the material being fed to the circumference of the separator wheel from the periphery of the separating chamber 25 and either or both of them being unequally distributed over the wheel circumference. The wheel 27 is housed in an upwardly tapering casing 24 mounted on the casing 19 of a beater mill and is rotated in the same direction as the beater mechanism 20. Material to be ground, e.g. corn, and carrier air enter the mill through inlet 32 and, after grinding by the beater mechanism 20, the granular material 40 is thrown upwards into the separating chamber 25 and carried by the air. The mixture is guided by the tapering shape of the separator casing and by inclined blades 41 to the circumference of the separator wheel 27. Inside the wheel channels the material is subjected to the opposite actions of centrifugal force and carrier air. The fine particles are entrained by the carrier air through the exit 34 and exhaust pipe 35. The coarse particles are flung out of the wheel, a greater portion of them being caught by the chamber periphery or a screen 42 and redirected to the wheel circumference to further separate fine particles adhering to them and a smaller portion being returned to the mill as at 39 for further grinding. Known means may be used to return the coarse particles repeatedly to the separator wheel for further cleaning. The screen 42 also serves to protect the separator wheel against the action of the granular material thrown from the mill and to limit the quantity of air passing into the separating chamber. Leakage of granular material through the clearance gap 37 is prevented by the introduction of scavenging air 38. In another construction of separator the carrier air enters the separator wheel over the whole of its circumference while the material to be separated is fed through a vertical pipe close to the circumference of the wheel at one place only. The wheel blades are slanted forward so as to catch the material being fed without spraying thereof. The vertical pipe may be of resilient material.

Abstract: 1,044,192. Friction gearing. RITTER CO. Inc. May 7, 1964 [Feb. 27, 1964], No. 19075/64. Heading F2Q. [Also in Divisions A5 and F1] A friction drive between the output shaft 58, Fig. 1, of a rotary sliding vane motor 17 and a driven member 173, Fig. 2 (not shown), connected by a threaded rod to a collet and chuck assembly driving a dental tool, comprises outer and inner ball-races 81, 83 and a retainer 84 for the balls 82 formed with dogs 88 for engagement with complementary dogs 201 on the driven member 173. For the efficient running of the motor it is essential for the clearances between the end faces of its rotor 26 and the adjacent end faces of a plug 16 and a member 98 loaded by a stack of Belleville washers 104 to be equal. To achieve this, firstly, a spring-loaded cup-washer 64 is adjusted inwardly and through a ball-bearing assembly 62 urges the shaft 58 and through stops 93 thereon the inner race 83 to the left. Secondly, a ring-nut 95 is adjusted inwardly to move the outer race 81 rightwardly and through a spacing collar 97 load the Belleville washers to move the member 98 to the right. On completion of the adjustment to equalize the clearances, the races 81, 83 are thrown out of alignment with respect to each other to impose a diagonal pressure therebetween, indicated by the arrow A which is dependent upon the initial adjustment of a spring 69 loading the cup-washer 64 to introduce a friction load on the retainer 84. This friction load causes the retainer and hence the collet and chuck assembly to rotate at a reduced speed as compared to the rotational speed of the rotor 26 and its shaft 58. Speed and direction of rotation of the dental tool is controlled by a foot controller controlling the compressed-air supply to the motor.
