Abstract: 583,675. Sampling granular materials. EDWARDS, R. L. Nov. 15, 1944, No. 22559. [Class 58] Apparatus for sub-dividing an agglomerate into aliquot parts comprises a container, a partitioning member comprising a plurality of radically extending partitions adapted to fit snugly into the container and thereby to sub-divide the material therein into aliquot parts, and a closure member permitting a selective discharge of the sub-divided agglomerate from each cell. In the construction shown in exploded perspective the apparatus includes an open-ended cylinder 3 having at its top a skeleton of radial bars 4, an assembly of vanes 1 extending from a tube 2, and a rotatable cover 6, these three parts being held together by a rod 8 having a boss 9 at one end and a nut 10 which is extended to form a handle 11. The nut bears on a spring washer which engages the cover 6 to hold the latter in yielding engagement with cylinder 3, and the cover has a lug 12 to facilitate its rotation. In use the vane assembly is held in the cylinder by rod 8 so that vanes 1 coincide with bars 4, and cover 6 is so positioned that an opening 7 therein coincides with one of the six cells thus formed. The entire device is then pushed into a container 13 containing the agglomerate thereby filling all six cells. Upon inverting the apparatus the contents of the cell opposite opening 7 is discharged, and subsequently the contents of any other cell or cells may be discharged on rotating the cover 6. In a modification of the apparatus the cover is made in two parts, one being fixed and the other movable, so that some cells are permanently closed at one end while the others may be uncovered when required. For dividing a sample into three parts the device may for instance have three cells, one being permanently open at both ends, one having a fixed cap at one end, and the third having a movable cap. In another modification a similar arrangement of caps is employed where the number of cells is a multiple of three.

Abstract: 535,129. Aircraft landing-gear. STONE, T. H. June 28, 1939, No. 22826/38. [Class 4] The wheel-carrying leg or equivalent structure retractable into each stabilizing float of an amphibian, swings about a pivot which can yield under landing and supporting loads to effect engagement of locking means to prevent retraction of the leg while the aircraft is supported by it. A pair of wheels may be mounted coaxially or in tandem in each float. In the form shown, wheels 18 are housed when retracted in a recess 17 in the float 13. The wheel mounting 19, which may include a shock-absorber, is pivoted at 20 in a bearing structure 21 adapted to transmit landing loads directly to the shockabsorbing struts 14. A pin 24 on the mounting 19 engages a slot 23 in the structure 21 which has an extension 25 into which the pin 24 enters when a spring 22 is compressed by landing load. When the wheels 18 are relieved of ground load the spring 22 urges the pivot spindle 20 downwards and the mounting is free to pivot under the action of hydraulic jacks 26. A hydraulic locking device 27 is interposed into the pipe 29 appropriate to extension of the undercarriage. As shown in Fig. 4, it comprises a pin 32 integral with a piston 31 in a cylinder 30 and adapted when extended from the cylinder to engage with the pin 24. Upon admission of fluid pressure to the pipe 29, fluid enters a port 40 and forces the piston 31 down until the pin 24 is released and a port 45 opened. Upon commencement :of the retracting movement, fluid returns from the jack through a port 41 and a one-way valve 46. A flap 49 hinged at 50 covers the opening in the float when the wheels are retracted. It may be connected to the mounting 19 by extensible links 51 which are in tension when the flap is closed, to secure watertightness. A one-way valve may be placed behind the step of the float 13 so that suction caused during take-off will draw off any water which may have entered the float.
