Title: Improvements in or relating to automatic or semi-automatic weighing apparatus
IPC: G01G1/00
Filed: 1927-06-23
Abstract: 293,963. Avery, Ltd., W. &. T., and Taylor, J. W. June 23, 1927. Pendulum-weight apparatus.-Relates to automatic or semi-automatic weighing-apparatus of the kind wherein the indicating pointer is carried by a pendulous resistant mounted on a knife-edge and connected by a flexible band to the lever system. In order to prevent damage to the knife-edge during transport of the scale, the invention provides a device for relieving and locking the knife-edge comprising a skewer-like member provided in its length with two adjacent portions of different shape in crosssection, preferably circular and non-circular, a part of each of the portions being capable of being engaged within correspondingly-shaped holes in the pendulous resistant, the non-circular part being also capable of engagement simultaneously within a correspondingly shaped hole in a fixed member whereby by passing the skewer-like member through the hole in the fixed member and through the holes in the pendulous resistant and bringing the holes into axial alignment, the knife-edge supporting the resistant may be lifted from its bearings and the resistant locked against rotation. The skewer-like member 17 has a square portion 17<a> and a cylindrical portion 17b these portions being capable of fitting into similarly shaped holes in the cam member 5<a>, 5b of the pendulum 6 and in the fixed friction plates 12, 13. When the skewer is thus inserted the knife-edge 8 of the pendulum is raised from its bearing 10, and owing to the intrusion of the squared portion 17<a> into the cam member 5<a> the pendulum is locked against rotation. By screwing-in a bush portion 14 of the friction plate 13 the parts are locked against lateral movement. Screw caps 16 normally close the holes in the casing.

Title: Improvements in or relating to the preparation of a nodulated support for a catalyst
IPC: B01J21/16
Filed: 1947-06-24
Abstract: A process for the production of a catalyst support consisting of china clay nodules comprises initially rolling finely powdered china clay in a rotating drum while water is applied to the mass in a fine spray until the percentage by weight of water present is between 20 per cent and 35 per cent, expressed as the loss of weight on ignition to red heat, continuing the rotation of the drum until grains of approximately spherical shape, e.g., 1-2 mm. in diameter, are obtained, and thereafter adding to the grains so formed further water in the form of a fine spray and further dry powdered clay until the desired size of nodule, having substantially the same water content as the grains, is obtained, then drying and firing the nodules.  The water may be applied through a spray gun.  In the example given, to form the grains 1 cwt. of clay is mixed with 1 gallon of water in a cylindrical drum inclined at 10 degrees to the horizontal and rotating at 16 r.p.m.  Further water and clay are added to form the nodules which are subsequently screened, pieces between 3/16 in. and 1/4 in. being retained for use, larger pieces being broken up and returned to the drum.  The graded material is then fired at a temperature of 950 DEG -1000 DEG C.  The completion of the manufacture, activation and application of the catalyst carrier may be as described in Specification 498,828, [Group III].

A hitch for coupling a tractor having a power operated lift with a harvester for maize or other row crops has a cross-member 45 with coupling pins 37 on arms 46 co-operating with coupling means 31 on the tractor T for connection thereto, supporting means 64 for a crop treating or husking unit disposed behind the tractor, and a standard 55 on an extended end of the cross-member for pivotal connection of a crop gathering unit H which extends alongside the tractor. Means provided on the crossmember are connected to the tractor power lift mechanism and operable thereby to move the gathering unit H pivotally between working and transport positions. In the construction shown the transverse pins 37 slide into rearward openings 36 in two coupling members 31 mounted on pads 25 on the tractor rear axle casings. The pins are retained by spring loaded latches 39 to connect the hitch to the tractor. Additional braces 47 and 48 are provided connected to the tractor by a pin 51 passing through lugs 52 on the rear casing and to the frame by pins 49. Brackets 61, 62 with rearward facing slats 64 and a bracket 63 support the husking unit 15 which is retained by brace 57 attached to standard 55 on the crossmember which is in turn braced by tractor top link 28. Mounted on the outer end of the shaft 45 is another standard 65 carrying a tubular housing 66 for a cross-shaft 67 about which brackets 69 bolted to the gathering section pivot to raise or lower gathering points 11, 11a from the ground. A cross-shaft 70 mounted for rotational movement in brackets 71 on crossshaft 45 has crank arms 72 and 75 attached to its inner and outer ends. Drop link 73 of the power lift mechanism is connected through link 74 with crank arm 72 and a cross-member 79 on the gathering arms is connected through thrust link 76 with crank arm 75. Thus the power lift mechanism controls the movement of the gathering arms. To unhitch the harvester from the tractor jacks 80 are lowered on either side of the frame to support the harvester, the gathering arms are lowered and extensible link 86 fitted between holes in crank arm 75 and in a frame extension 87 to prevent rotation of shaft 70, pin 51 removed from lugs 52, latches 39 on the mounting plates 31 released by levers 44 and top link 28 and drop link 73 disconnected when the tractor can be driven forward without the harvester. The frame can be re-aligned with the tractor if it has settled by manipulating jacks 80 and extensible links 86. The frame may alternatively extend on both sides of the tractor to support two gathering units extending on both sides.
