Title: Means and method for extracting true proportionate sample of fluid material
IPC: G01N1/10
Filed: 1958-10-14
Abstract: 860,043. Sampling liquids. JAQUITH, B. K. Oct. 14, 1958 [Oct. 28, 1957], No. 32801/58. Class 106(5) For obtaining a true sample of a flowing material of variable composition, such as milk, which varies in butter fat content between the beginning and end of a milking operation, a proportion of the material is intermittently diverted on to the surface of a constant-level pool and a portion of the crests of the waves thus created is led into a collecting chamber in which the samples taken at spaced intervals accumulate. The inlet 18 of a housing H is connected to the teat cups of a milking machine and discharges through a de-aerating and depulsing baffle B to a pair of tipping measuring buckets 33 on a shaft 31 connected to a counter. As the buckets tip to one side or the other, they discharge into wells having weirs 37 or 39 over which the milk flows to an outlet 19 leading to a storage tank. The sampling device is fitted to one well and comprises a container S securable to the housing H by slotted clips 51 and pins 53 and having a tube 55 which has an orifice 56 slightly above the level of the weir 37. Each time the right-hand bucket discharges against the rounded side of the housing, the crests of the waves spill over the orifice 56 into the container S. At the end of the milking period, a ball valve 58 is removed from the end of a spigot 57 on the container and the vacuum in the system draws a tube 61 upwards to seal on the bottom of the tube 55. Air entering through the holes 65 in the tube 61 agitates the accumulated sample and drives the greater part of it through holes 67 and the two tubes 61, 56 to the storage tank, leaving only a sufficient representative sample which discharges through the holes 65 and the spigot when a milk valve on the machine is closed and the fall in vacuum allows the tube 61 to descend to its lower position.

Patent GB-768283-A (GB)
Title: Extrusion die assembly with flow-correcting baffle plate
IPC: B21C25/02
Filed: 1954-11-12
Abstract: 768,283. Extruding. DOW CHEMICAL CO. Nov. 12, 1954 [Dec. 18, 1953], No. 32896/54. Class 83 (4). In an extrusion die assembly having an extrusion die 15 with at least one extrusion orifice 16 and in which the rate of flow of the metal through the die during extrusion tends to be more rapid at one point than at another, a baffle plate 17 having a baffle opening 25 in alignment with and larger than each die orifice is provided in front of the die plate, the baffle opening being so shaped as to regulate the flow of extrusion metal through the die orifice or orifices so as to substantially equalize the rate of flow therethrough. The die assembly comprises the baffle plate 17, die plate 15 and a backer plate 18 all made from heat-treated tool steel and assembled together in a die holder 19. Relative rotation of the parts 17, 15 and 18 is prevented by dowels 28. In one embodiment, Fig. 5, for extruding a bar of L-shape cross-section, preferably from a pre-heated billet of magnesium-base alloy, the die plate has an orifice 16 corresponding to the cross-section of the extruded bar, and the baffle plates 17 has an opening 25 which is enlarged at the ends. Maximum resistance to flow through the orifice 16 is at the outside end of the limbs, and minimum resistance to the flow is at the vertex or junction of the limbs 14. Therefore the baffle opening 25 is made widest relative to the die opening at its outside ends and narrowest near the vertex whereby the ratio of the width of the baffle opening to the corresponding width of the die orifice is greater at the ends of the limbs, tending to less rapid flow, than at the vertex 14, tending to more rapid flow. The walls of the die orifice 16 and of the baffle opening 25 are preferably parallel but in the case of the die orifice 16 a taper may be arranged to produce a choke. Other embodiments are described for producing extruded bars of rectangular cross-section, Fig. 10 (not shown), and of tubes with external radial ribs, Fig. 11 (not shown). In another embodiment, Fig. 12, the die plate has three equal orifices 16c, and the rate of flow during extrusion tends to be more rapid at the central orifice than at the outer orifices. Therefore the baffle plate 17 has baffle openings 25c which are larger than the central baffle opening 25d thereby equalizing the rate of flow through the three orifices. Examples are given of the dimensions of the die plate and the baffle plate.

Title: Improvements in pot furnaces for glass smelting
IPC: C03B5/06
Filed: 1931-11-27
Abstract: 384,074. Glass furnaces. SCHœFFLER, J., 101, Ruhrallee, Essen, Germany. Nov. 27, 1931, No. 32952. [Class 51 (ii).] A pot furnace for melting glass is heated by one or more tangentially delivering burners 6 of the type in which gas and air are burnt in narrow passages in a refractory brick, and the combustion products escape through a number of dampercontrolled ports 9 in the floor leading to two waste gas flues 10. The dampers are so set that the effective openings of the ports increase in the direction of flow of the gases. Passages 12 are also formed beneath the pots and from these damper-controlled flues 13 lead to the flues 10. The waste gases are exhausted through flues 16 containing removable pipes 17 for heating the air for combustion. In the event of the fracture of a pot the glass runs down inclines 11 into the flues 9, and is collected in a sump. When a number of melting chambers are built together in a battery provision may be made for passing the waste gases from one chamber into another which is temporarily out of action, but which needs to be kept hot.

Filed: 1948-12-23
Abstract: 656,039. Disc-harrows. JOHNSTON, H. M. Dec. 23, 1948, No. 33122. [Class 6(i)] A disc-harrow comprises a shaft 15 forming the main part of the frame A which carries wheels 17, 27, 28 at its ends and the disc tools 13 are mounted on and spaced from a tube 10 encircling the shaft 15, so that, by rotation of the tube on the shaft, the tools may be lifted for transport, adjusted manually for depth, or enabled to yield momentarily to clear obstructions. A bifurcated hitch C is mounted at the front of the device and one of its arms 22 is connected to the front wheel 17 so that the wheel will be guided by the motion of the towing tractor. The rear end of the shaft 15 is supported by a carriage B having a rear wheel 27 and a front wheel 28 provided with a half-revolution clutch 29 for lifting the tools. The discs are mounted on a shaft 12 supported by brackets 11 on the tube 10. At one point the tube is encircled by a pair of split sleeves 33 carrying upstanding lugs 34. Arms 35 are pivoted at 36 to the lugs, and are fixed to a bracket 51 at their upper ends, the bracket being connected by an adjustable rod 55 to a crank 30 movable by the clutch 29. A trunnion 47 connects the arms 35 to a member 46 enclosing a threaded rod 49 and forming the manual adjustment. The rod is pivoted to an arm 45 secured to the tube 10, and is extended or contracted by manually-operable bevel gearing 48. A bolt 38 extends through a slot 37 in each lug 34 so that the arms 35 can move relatively to the lugs within the limits of the slot. Springs 71 are connected between eyes 67 carried by brackets 65 and further eyes 69 on the member 51. The arms 35 normally extend radially to the tube 10 but can swing about the pivot 36 if the tools rise on encountering obstructions, the arms 35 and lugs 34, thus forming a spring-loaded toggle linkage. The toggle arrangement can be rendered inoperative, when desired, by the insertion of an additional pin in the slot 37.
