Title: Centrifuge construction
IPC: B04B1/20
Filed: 1972-09-19
Abstract: 1346387 Centrifugal separator PENNWALT CORP 19 Sept 1972 [23 Sept 1971] 43427/72 Heading B2P [Also in Division F2] A centrifuge, of the type having an internal helical screw conveyor 18 within the centrifuge bowl 14 which is mounted in an internally gas-pressurised casing 12, is provided with a lubricating and sealing arrangement for lubricating a bearing 72 located between the bowl and the conveyor. This arrangement includes a rotatable lubricant reservoir 64 located within the hub 20 of the conveyor and having a flexible wall 56 exposed at its external surface 57 to the internal gas pressure transmitted from the separation chamber 28 within the bowl via a passageway 84a to pressurise lubricant contained in the reservoir. The reservoir is bounded by perforated walls 52, 58. The lubricant is supplied in operation by the action of centrifugal force from the reservoir via an annular chamber 66 and a passageway 68 to an annular bearing cavity 70 extending between annular seals 74a, 74b and 74c, 74d disposed between the bowl and the conveyor on each side of the bearing 72. The gaseous pressure is transmitted via the flexible wall 56 and the lubricant to bearing cavity 70 and acts upon the interior surfaces 80b, 80c of seals 74b, 74c. The gaseous pressure also acts upon the exterior surface 76a of seal 74a via a passageway 77, and upon exterior surface 76d of seal 74d via passageways 79, 81. The gaseous pressure is also transmitted to annular spaces 98a, 98b between the seals 74a, 74b and 74c, 74d respectively via passageways 88a, 88b. Thus the pressure is substantially equalized on opposite sides of the bearing seals resulting in better sealing. The seals 74a arid 74d are primarily used to keep solids discharging through opening 32 in the bowl away from the seals 74b and 74c respectively. During operation, lubricant gradually leaks past seals 74b, 74c into the annular spaces 98a, 98b, and is discharged by the action of centrifugal force through passageways 88a, 88b into a stationary collecting chamber 84. A passageway 94 extends from space 106 below the chamber 84 to the tangential discharge opening 44 for separated liquid.

Abstract: 1379329 Valves BENDIX CORP 17 Sept 1973 [15 Sept 1972] 43559/73 Heading F2V A valve controlling flow of fluid from source 13 to receiver 15, e.g. an air motor, so as to maintain a desired pressure differential P 1 -P 2  across the latter comprises a closure member 18 co-operating with flow orifice 16 and connected to actuating piston 28 slidably mounted in casing 10 defining therewith a chamber 30 subject via passage 64 and damping restriction 66 to the pressure P 2  downstream of receiver 15. Chamber 30 contains concentric springs 54, 56 urging closure member 18 in the opening direction. Spring 54 is active throughout the range of travel of closure 18 whereas spring 56 is active only in that part of the range in which a first tapered face 22 of closure 18 controls the effective flow area of orifice 16. The latter is controlled in the remainder of the range by a second face 20 of different taper, e.g. 20 degrees, compared with 10 degrees. Thus the relationship between flow area change and valve travel varies over the operating range. Closure 18 is urged in the closing direction by pressure P 1  acting thereon, pressure Pb having no influence since the effective areas of closure 18 and piston 28 are equal. Piston 28 includes a peripheral recess 70 communicating any leakage of pressure Pb via passage 68 to passage 64. Adjustable stops 40, 72 are provided to limit the travel of closure 18 in the closing and opening directions respectively. The controlled fluid may be liquid or gas.

A PN junction semi-conductor device, is produced by heating to 750 C. on a semi-conductor substrate 1, a small piece of lead 6 containing indium and antimony, and cooling the assembly to normal atmospheric temperature so that a layer 7 of P-type conductivity is first formed adjacent the substrate and a layer 8 of N-type conductivity is subsequently formed on the first layer. The substrate may be of N- type, intrinsic, or weak P-type germanium. An alloy of 90% lead, 9% indium and 1% antimony (by weight) is alloyed at 750 C.for 5 minutes to an N-type germanium substrate of specific resistance between 5 and 50 ohms-cms. When the assembly is cooled supercooling occurs, with subsequent recrystallization occurring at a rapid rate. The effective segregation coefficients of the impurity materials change to different extents during recrystallization so varying the relative concentration of each material in the molten liquid. The thickness of the P-type layer may be varied by changing the ratio of the weights of indium and antimony in the lead carrier. The specific resistances of the two layers are also varied in the same way.
