Title: Centrifugal separator
IPC: B04B11/02
Filed: 1957-06-06
Abstract: 823,888. Centrifugal strainer separators. PECK, N. O. June 6, 1957, No. 18091/57. Class 46. [Also in Groups VIII, XXIV and XXXIV] A basket comprising a bottom plate 41, Fig. 1, a series of vertically-spaced horizontal rings 46 joined by posts 43, Figs. 5 and 6, and an upper ring 44, is mounted on a shaft 32 which is driven by, and in the same direction (counterclockwise) as, a hollow shaft 27 connected to a carrier 25, Fig. I. The carrier consists of a bottom plate 55, a downwardly-divergent wall 58 and a top plate 57 and is provided with four grooved idler rollers 64 and four eccentricallymounted grooved tensioning rollers 68, Fig. 8. Two of each kind constitute a set and each set accommodates a series, 49 or 50, Fig. 6, of endless bands 52, Fig. 8, each band 52 occupying corresponding grooves on the rollers. The inner reaches of the bands are urged into engagement with, and close the apertures between, the rings 46 of the basket, Figs. 5 and 6, by appropriate adjustment of the rollers 68. A shoot 85 for introducing, to the interior of the basket, material fed in at 82 consists of apertured vanes 87 and branches 86, and it is constrained to rotate with the carrier by connection 101, its lower end being mounted on a ball bearing at the top of shaft 32 (see Group XXXIV). The basket rotates at a few r.p.m. less than the carrier, so that during operation the rings 46 (see especially Fig. 6) rotate at a few r.p.m. clockwise relatively to the set of rollers 64, 68 and in consequence of the frictional engagement of the rings 46 and bands 52 the rings drive the bands round the rollers at this speed. The feed shoot 85 is fixed in relation to the sets of rollers so that material ejected from one branch 86 will reach and travel around with the rings and with the portions of the bands than in contact therewith, liquid being expelled between the rings and bands and being received in an annular trough (not shown) adjacent the lower lip of the carrier wall 58. After less than half a revolution the solids reach a region 74a where the bands leave the rings, and the solids are ejected between the rings and pass down an outlet trunk 74 integral with the carrier. The shaft 27 rotates in roller bearings 28, 29. It has a gear 113 mounted on its lower end which drives, through sets of gears 121, 122 . . . a gear 115 mounted on the lower end of shaft 32. The speed ratio may be altered by changing the positions and sizes of the gear sets (see Group XXIV). When the shaft 27 is driven at 1400 r.p.m. and the shaft 32 at from approximately 5¢ to approximately 9 r.p.m. less than this, the solids are retained in the basket under centrifugal force for from approximately 3À9 to approximately 2À3 seconds respectively.

Patent GB-664970-A (GB)
Title: Improvements in or relating to variable transmission gear systems for gun-mounts
IPC: F16H37/08
Filed: 1949-07-08
Abstract: 664,970. Variable-speed gear. VERWALTUNGSGES. DER WERKZEUGMASCHINENFABRIK OERLIKON. July 8, 1949 [July 12, 1948], No. 18177/49. Class 80 (ii). Two. entirely independent variable-speed gears having a common input such as an electric motor 13, internal-combustion engine or compressed-air motor, and independent output shafts 7, 10, operating respectively elevating and training gear on a gun, each comprise a three-element bevel planet train, one element, a side-wheel 39 of which is invariably driven at input speed through spur gears 16, 37, 23-24, 40; a second element, side-wheel 42, is connected to the respective output shaft 7 or 10 through simple clutched bevel reverse-gear 46; whilst its third element, the planet-carrier, is variably driven by the combined effect of a continuously variable gear of the hydraulic, electric, pneumatic or mechanical type, shown as a cone-and-idler friction gear 15, 18, 21, and of two spur-wheels 24, 33 invariably driven at fixed dissimilar speeds corresponding to the extremes provided by the friction gear, through spur gears 16, 37, 23-24 and 17, 36-34, 33 respectively, and each connected by a disc-clutch 28, 31 with a variablespeed pinion 29 driving a wheel 30 integral with the control planet-carrier. The variable-speed pinion 29 is mounted on a screw-thread 26 on the output shaft 22 of the friction cone 21 so as always to rotate at the adjusted speed of the cone 21 but to be screwed axially in one direction or the other in accordance with relative speeds produced by varying the speed of the cone 21, so as to engage one or other of the two friction clutches 28, 29, the engaging pressure on which is then produced by the torque-responsive axial thrust on helical gear teeth of the wheels 29, 30. Thus the pinion 29 is displaced axially to one side or the other in accordance with relative speed and torque conditions until it eventually rotates at the same speed as the adjusted speed of the cone 21, and although the main drive to the control carrier-wheel 30 is always under the direct control of the friction gear, the torque passes to it mainly through the clutches 28, 31, and the friction-gear torque is used only as a central force determining the relative proportions passing through the clutches and is thus quite small. The friction idlers 18 pivot on arms 19, axially movable along pivot-shafts 20, which have eccentric bushes for pressure adjustment. Action is summarised by a numerical example assuming an input speed of 3,000 r.p.m., which results in a fixed speed of 1,500 r.p.m. for the bevel side-wheel 39; fixed speeds of 3,000 and 2,250 r.p.m. for the clutch-wheels 24, 33; and a range of 2,250 to 3,000 r.p.m. for the output shaft 22 of the friction cone, adjustment of which thus provides a speed range of 750 to 1,000 r.p.m. for the planet-carrier wheel 30, corresponding to a speed of the final output shaft 7 or 10 of zero to plus or minus 500 r.p.m.

Abstract: 1,108,153. Electronic counters. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 29 June, 1965 [1 May, 1964], No. 18197/64. Heading G4A. A reversible binary counter operates to a 1125 weighted code. For addition the add line is marked negative and the subtraction line is earthed, so holding inoperative all the gates in the lower part of the Figure. Input pulses are applied to the strapped X and Y terminals. Initially each pulse opens AND gate G1 to reverse stage B1, the second pulse restoring B1 and resulting in a pulse from Q1 through G4 to set stage B3. The third pulse sets B1 again and opens AND gate G3 which, through N, closes G1. The fourth pulse, therefore, does not affect B1 but sets B2. G3, N and G1 then restore so that the fifth pulse restores B1, whereupon G4 restores B2 and B3 and sets B4. Pulses 6-9 operate in the same manner as pulses 1-4. The tenth pulse restores all stages and supplies a carry pulse from Q4. Subtraction takes place in the reverse order.
