Abstract: 1525105 Centrifugal separators and filters MANNESMANN AG 3 Sept 1975 [6 Sept 1974] 36338/75 Headings BID and B2P An apparatus for separating solids and liquid from a mixture thereof comprises two interconnected concentric annular chambers 1, 1', Fig. 1, arranged in a container 2 which has a tapering lower portion and is provided with an outlet 8 for separated solids, the external chamber 1 having a tangential inlet 3 for the introduction of the solids-liquid mixture; an adjustable guide plate 7 arranged adjacent the lower portions of the chambers 1, 1' and having a deflecting surface for directing purified liquid exiting from chamber 1 upwardly through the chamber 1', a conical extension of the guide plate 7 defining with the radially outer wall 4 of the chamber I an annular gap 6 for the passage of separated solids; and an overflow 10 for discharging the purified liquid from the container. The container may be pressureless or pressurized as shown in the left-hand and right-hand half of Fig. 1 respectively. A baffle 9 is provided above the outlet from chamber 1' for uniform distribution of the purified liquid. A portion of the liquid is discharged with the solids through the gap 6 and, after reversing, flows upwardly to discharge with the bulk of purified liquid via the overflow 10 and an outlet tube 11. A filter bed 16 may be provided between the chambers 1, 1' and the overflow 10. A flocculating agent may be added to the mixture before it enters the chamber 1 to improve the separation of very fine solid particles. In Fig. 4, a separating plate 13 is provided above the chambers 1, 1'. Tubes 14 extend through the plate and serve to conduct purified liquid. Tubes 15, for the removal of floating substances, extend directly from below the plate 13, upwardly through the plate and open either directly out of the container (right-hand portion of Figure) or into a collecting conduit (left-hand portion).

Title: Improvements in or relating to sluice valves
IPC: F16K31/54
Filed: 1933-12-27
Abstract: 417,424. Actuating valves. LE ROUZIC, Z., 85, Rue de l'Est, Lille, Nord, France. Dec. 27, 1933, No. 36365. Convention date, Dec. 27, 1932. [Class 135.] The spindle 6 of a sluice valve is pivoted on an axis x-x to a pair of symmetrically arranged pinions 12 rolling inside stationary gears 13 of twice the diameter. The axis x-x coincides with the pitch circles of the pinions and therefore moves in a straight path during the rolling movement. As shown in Fig. 1, the spindle 6 is fixed to a cross-head 8 carrying two trunnions 9 engaging cheeks 7, to which the pinions 12 are keyed, and which are carried on crank-pins 5 on cranks 2a formed on the shaft 1. The shaft 1 may be driven by hand through the pinion 3 or by fluid pressure through the pinion 4, automatic change-over being effected by the device shown in Fig. 3, the manually driven worm wheel 3 being declutched at 24 when fluid pressure is transmitted through pipe 31 and valve 33 to piston 28, which then moves the clutch lever 25 about its pivot 26 against the action of a spring 29. The pipe 31 communicates with the inlet port of a cylinder containing a piston, the rod of which is formed as a rack to operate the pinion 4. When the operating pressure is relieved by opening the byepass valve 34, the spring 29 re-engages the clutch 24. Spring washers may be interposed between the cross-head 8 and a collar on the spindle 6.

Filed: 1956-11-29
Abstract: 825,515. Peanut-gathering machines. LILLISTON IMPLEMENT CO. Nov. 29, 1956, No. 36501/56. Class 6(3).  A machine for gathering peanut plants from a windrow and stripping the nuts from the plants comprises a frame 10 with a forward pick-up portion 19 adjacent to the ground, a conveyer 22 which picks up the plants and carries them over the forward portion to a picking mechanism which is aligned with the forward portion to form a straight passage for the plants through the machine. The frame 10 is triangular in side elevation and is supported by a draught-bar 13 at the front and wheels 12 at the rear. The conveyer 22 comprises chains interconnected by tine-bars 20, the tines 23 of which pick up the plants and carry them around a forward sprocket 24, over a ledge 36<SP>1</SP>, which prevents loose peanuts from rolling back, and across a separator screen 36 to the picking screen 37, Fig. 7. The screens 36, 37 are co-terminous and co-planar and form a perforated base to the conveyer 22 throughout its length. The separator screen removes dirt from the plants as they pass thereover. The picking screen is of expanded metal with lattice openings through which the peanuts dangle as the plants are dragged over it, the plants being simultaneously agitated by short endless tine-bar conveyer 40, arranged above the conveyer 22 and driven at a higher speed. Further combing action is provided by spring tines 30 carried by bars 32 forming a table suspended by chains 33<SP>11</SP> above the entire length of the conveyer 22, the separated peanuts falling through the mesh floor on to an endless belt 47 which carries them to a hopper 49. The hopper is suspended on pivoted links 51 and is reciprocated thereby ; the links carry, at their lower ends, oscillating grids formed by fingers 50 within the hopper, and an air-blast is delivered by a fan 56 to winnow away light trash. Saws, Fig. 2 (not shown), project through the inclined base of the hopper to cut off stems from the peanuts as they roll down towards a bagging elevator 60. The frame 10 is pivoted to the draught-bar 13 about the wheel-axle 11, and the bar carries the engine 29 on a superstructure 16, adjustment of the frame relatively to the draught-bar being effected by a hydraulic ram, Fig. 2 (not shown), connected between them and supplied with fluid from the propelling tractor.

In a crank-case ventilation system in which a coil spring is arranged inside a blowby passage, the coils are spaced when the spring element is uncompressed to allow gas flow and the coils engage one another to prevent gas flow when the spring is compressed by fluid pressure. During normal engine operation blowby gases pass via conduit 30 in the direction of arrow 74 through the central cavity 60 of coil spring 56 and thence via passage 30 to air filter (20), Fig. 1 (not shown). If an induction backfire occurs the flame pressure front strikes cap 62 and compresses spring 56 to extinguish the backfire. Passage 32 communicates with inductor passage 28 and orifice 42, which is kept clear of obstruction by plunger 50, limits the blowby flow to passage 32 and thereby regulates the fuel/air ratio.
