Title: Improvements in or relating to combine harvesting machines
IPC: A01F12/44
Filed: 1959-06-01
Abstract: 857,573. Combine - harvesters. ALLISCHALMERS MANUFACTURING CO. June 1, 1959 [June 9, 1958], No. 18686/59. Class 6(3). A combine-harvester is provided with an endless riddling conveyer 23 between the threshing cylinder 12 and the straw-rack 36, which is mounted above the dressing shoe 81, the straw-rack being longitudinally adjustable so as to permit direct passage of fine or shredded material from the end 93 of the conveyer to the dressing shoe. The conveyer is slatted and slides over a pan 34 to carry all the threshed product to the discharge end 93 where it normally falls on the straw-rack comprising three identical toothed straw-walkers mounted on multi-throw crank-shafts 37, 38 so as to oscillate 120 degrees out of phase. Straw is discharged at the rear ends of the racks and the corn and chaff fall into the dressing shoe where chaff is winnowed away by an air-blast from a fan 84 and the grain falls through sieves 82, 83 on to a pan 87 which delivers it to an auger 88. Unthreshed ears are retained by the sieve 82 and pass through a grating 89 into a pan 91 whence they are returned to the threshing cylinder by an auger 92. When large amounts of fine material are present in the threshed product, the straw rack can be adjusted rearwardly, Fig. 8, to leave a vertical gap 98 through which fine material can fall directly into the dressing shoe. Each straw-walker, shown in inverted plan in Fig. 3, consists of a gridded portion 61 admitting the grain and chaff to a trough formed by downwardlyconvergent walls 56, 57. The base of the trough is bolted to a stepped member 42 and is adjustable thereon by means of slots 72, 73, and bolts 76, the member 42 carrying the journals 64, 65 for the crankshafts 37, 38.
Patent GB-678003-A (GB)
Title: Improvements in machines for testing nuts and bolts, and like fastenings
IPC: G01N3/00
Filed: 1949-07-16
Abstract: 678,003. Testing nuts and bolts. FORGAARD, H. L. July 17, 1950 [July 16, 1949], No. 18772/49. Class 106 (ii). In a machine for testing fastenings such as a nut and bolt 48, 49, Fig. 1, a reciprocating and rockable head 46 is provided for applying a force, other than a simple rotative force, to the innermost end face of the nut at points offset from the axis of the nut, the force being successively applied at positions which are angularly spaced apart around the axis of the nut. The bolt is mounted in a two-part sleeve 38, 39 adapted to move under the action of a piston 21 within a cylinder 25. A conical recess 44 at the upper end of the sleeve 39 supports a rounded portion 45 of the rockable head 46 through which the bolt also passes with clearance. Screwed into the upper end of the cylinder 25 is an abutment block 29 from which extend two pins 31, 32, the pins terminating at different distances from the rockable head 46 so that on each upward stroke, the rockable head strikes the nearest pin and is deflected to deliver an oblique blow to the nut 48 on its innermost end face and at a point spaced away from the axis of the nut. The second pin limits the rocking movement of the head. The piston 21 is mounted on an archimedean screw 19 rotatable in a fixed nut 59 and has two ,spring-loaded plungers 34 engaging two of ten corresponding recesses 9 in the member 38. Thus, on each upward stroke, the piston 21, the two-part sleeve 38, 39, and the test-piece are all rotated through a small angle by the archimedean screw 19. For the return stroke, the piston 21 is sucked downwardly, causing it to rotate in the reverse direction whilst the twopart sleeve 38, 39, descending of its own accord, fails to be engaged by the pins 34 and is not, therefore, rotated in this reverse direction. The next upstroke rotates the test piece through a further angular displacement and the resultant oblique blow on the nut is thus angularly displaced from the position of the previous blow. Should the test-piece fracture or fail, the members of the two-part sleeve 38, 39 are free to rotate relatively to each other, this relative movement permitting channels 57, Fig. 2, in the upper member 39 to pass over co-operating recesses 54 in the lower member 38. When this occurs, loose bodies, such as balls 55, are blown out of the recesses 54 through the channels 57 and out of a hole 52 in the. cylinder 25 to indicate that a failure has occurred, there being a hole 56 at the bottom of each recess 54 coinmunicating with the actuating source of air 12. The passage of air through these holes 56 on the failure of the test-piece is audible. The inner end of the abutment block 29 engages a distancetube 24 in the cylinder 25, the effective length of the distance-tube 24 being adjustable by providing it with one or more removable short sections 26, 27.

Title: Improvements in vacuum electric tube devices
IPC: H01J9/04
Filed: 1928-06-28
Abstract: 319,823. Cachemaille, A. S., (Westing- house Lamp Co.). June 28, 1928. Vacuum tubes.-An activated laver is formed on an electrode, such as a tungsten thermionic cathode, by heating substances consecutively to temperatures at which they yield an electronegative element, such as oxygen, and then an electropositive element such as an alkali metal, preferably caesium, the heating operation being performed during evacuation or after evacuation and sealing off; a gettering substance may be heated subsequently. The substances may be mounted on the grid 13 or anode 19, or on a platform 28, which prevents deposition on the mount 16, and is slotted to receive the supports for the electrodes. The substances may consist of (a) barium or manganese dioxide, (b) caesium or rubidium or a compound such as caesium with magnesium, and (c) misch metal. After the envelope has been evacuated and baked, it is placed within a coil 34 supplied with high frequency current so as to effect the liberation of oxygen at a temperature of 400-600‹ C., the cathode 11 being subsequently lighted or flashed to cause a layer of oxygen to be deposited on it. Excess oxygen is pumped out, or some may be left to form caesium oxide for the removal of hydrogen. Alkali metal is liberated by heating to 700 - 900‹ C., and subsequently the misch metal is heated to 1000-12000‹ C. The grid and anode consist each of discs with apertures in the centre through which the cathode extends, the apertures in the grid discs being of smaller diameter than those in the anode discs.

The bottom of each channel member is cut away at 8 and 9 so that a packet may be withdrawn from a selected one of two sides, the inoperative opening being closed by a strip 12 secured to the base, rotation of the base through 180 degrees serving to close either of the openings as desired. Adjacent columns may be connected together at their upper ends by plates 14. In a modification (Fig. 6) the device comprises a number of vending units with a common wall each unit having side walls forming pairs of back-to-back channelsectioned columns which are closed by removable interchangeable panels one being a brand indicator panel composed of dummy packets or the like. In this modification the plate 30 secured to the base and closing one of the two discharge openings may be dispensed with and the recesses 25 which receive pins on the closure panels may be at different lengths on opposed sides of the device such that on one side a closure panel closes a discharge opening. In this change from selfservice to sales service is effected by turning the device 180 degrees on the base.

Title: Improvements in filter
IPC: B01D33/067
Filed: 1951-08-10
Abstract: 687,095. Drum filters. YOUNG, F. W. Aug. 10, 1951, No. 18909/51. Class 46 In a continuous vacuum filter of the horizontal rotary drum type wherein a series of division strips 26, Fig. 3, divide a base 20 into contiguous filter compartments sealed one from another and provided with drains 24, each strip 26 has a cylindrical outer surface secured along a narrow longitudinal area thereof, as by welding 27, to the base 20 so that portions overhang the base on both sides of the strip. Perforated bridges 32 fit the compartments with their depending longitudinally extending flanges both supporting the bridges in spaced relation to the base 20 and also holding them against outward movement by the locked engagement of the sides of the flanges with the overhanging portions of the strips. The strips 26 are formed as slotted metallic tubes with the slot edges folded back at 28. A filter fabric of wire or cloth 34 is held in place on the bridges 32, after the latter have been slid endwise into place by pressing down a portion of the fabric by means of a narrow smooth tool into the open throat of a tube 26 and inserting from the slot end, a retaining rod 36 to overlie the portion. The fabric is then stretched over the adjacent bridge 32 and the procedure repeated. To provide a seal at both ends of the drum circumferential grooves are cut in the edges of the steel base 20. The sides of the filter fabric are drawn down over the ends of the bridges 32 and depressed into the grooves, hard sash cord being pounded thereinto over the fabric as caulking to retain the fabric in position. The drum 10, Fig. 1; rotates within a vat 12 containing a mixture 14, the level of the mixture being controlled by inlet piping 16 and a system of valves and dams 18. By pumping means and piping 25 the pressure within drum 10 is maintained below that outside it, the filtrate 15 thus being forced through the filter medium and removed by pipe 25. The cake 53 is discharged by a blowback system comprising a chamber 46, pipe 48, and baffles 50, 51. An upward extension 54 of the baffle 51 restricts the opening 47, through which compressed air is forced, to approximately the width of a port 24. The level of filtrate 15 is maintained above the bottom of baffle 51 but below baffle 50 by means of pipe 25 to provide a liquid seal in the area of the lower baffle, the seal at the upper baffle 50 being maintained by the gravity flow of filtrate and the rotation of the drum.

Surface-areas, computing.-Relates to machines of the type wherein are employed a series of equidistant measuring wheels under which the material, such as leather, is passed, and consists in the substitution for the single wheels of twin measuring wheels arranged close together and so connected to the toothed wheels carrying the indicator actuating cords that these are not affected until both measuring wheels are engaged by the surface to be measured. The ordinates measured by the twin wheels are equivalent to these measured by wheels of negligible width occupying positions between the two sets of wheels. In the form shown in Figs. 1 and 2, twin wheels 10 are continuously driven by a feed roller 9 and are each carried by levers 11 pivoted on a shaft 12 and provided with adjustable stops 11' engaging weighted levers 14 pivoted at 13. When both sets of stops 11' are removed by the leather from the corresponding levers 14, these are rocked by weights 16 to bring toothed wheels 15, having secured thereto the usual cords 19, into engagement with pinions 17 driven from the wheels 10. When either wheel of a pair of wheels 10 falls out of engagement with the leather, its lever 14 is rocked to disengage the wheel 15 from the pinion 17. In a modification, twin tracer wheels are employed, and when both are in engagement with the leather locking detents are removed from ratchet wheels carrying the indicator actuating cords, thus allowing the wheels to be rotated by spur gearing through friction clutches by the feed roller.
