Abstract: 717,494. Sheathed electric heaters; hotplates. SIMPLEX ELECTRIC CO., Ltd. Nov. 6, 1951, [Nov. 10, 1950.] No. 27470/50. Class 39 (3). [Also in Group XXII] The heater comprises a metal tube or sheath in which a metal resistance wire 13 or strip, preferably coiled, is embedded in powdered insulating material, which is compacted by pressing the heater between dies in two stages, the first of which leaves the major part 12 of the sheath with substantially the same circular shape of internal cross section and forms the sheath with one or more longitudinal ribs 10 containing insulation. In the second stage the element is compressed between two dies 22, 24 which may be flat or formed with a shallow elliptical recess and deform one or both of the parts 12 still of circular cross section, whereby the sheath is flattened and the powder is uniformly compacted. Between the two pressing stages, the element may be bent to a U for an immersion heater or to a spiral for a hot-plate. Thus dies 22, 24 may be used in the final compacting of a hot-plate. The preliminary pressing may be carried out substantially as in Specification 592,124 and may be in several steps, so the parts 12 remain circular, but of decreasing radius. The helical resistance wire substantially retains its shape.

Filed: 1955-10-04
Abstract: 793,384. Breaking. CRANE PACKING, Ltd. Oct. 3, 1956 [Oct. 4, 1955], No. 28230/55. Class 83 (4). [Also in Group XXVI] A segmental sealing ring of carbon, iron or other crystalline material is produced by making the ring in one piece and then deliberately fracturing it into two or more, preferably substantially equal, parts. The rough mating surfaces ensure keying of the parts when subsequently clamped in ring formation by any suitable means such as a metal-reinforced rubber cup having a tapered bore, the parts of the ring having a complementary external taper. The fracturing may be effected by clamping the one-piece ring 5 between members 1 and 2, each comprising two substantially semi-circular elements arranged to leave two diametrically aligned gaps 4 and subjecting the assembly to a sharp blow to break the ring at the gaps 4. If desired, more than two gaps may be provided in the members 1 and 2. Alternatively, the ring may be broken along a diameter by the knife-edged ram of a hydraulic press, the ring being supported either on a rubber pad or on a rigid support, such as two pieces of metal, having a gap directly below the ram. The fractured parts may be mounted in ring formation and lapped, at least on the sealing face, to remove any surface damage sustained when fracturing the ring.

Internal helical fins 115 act as guides for the crop and sheets 140 extending across the front of the section impart a rearward movement to the crop. As shown, the impellar 34 comprises three vanes 114 mounted on a support 120 on a rotor 74 of the rotor 32, the outermost edges of the vanes describing a cone similar to the frusto conical section 54 when they are rotated. Two transition members one comprising an upper sheet 140 and a channel member 82 and the other a lower sheet 142, define a crop feed opening 145 to the region 54 and are slanted in opposite directions such that as the vanes 114 rotate, they impart a rearward movement to the crop (Figure 9). The rotor shaft 74 is supported at its forward end in a bearing assembly 76 mounted on the channel member 82 itself mounted on a chassis. The assembly 76 comprises a bearing casting 78 having a radially extending portion 80 which diverts crop away from the rotor shaft 74 to prevent binding of the crop thereon. The bearing assembly 76 comprises a spherical bearing including an inner race member 166 on the shaft 74 and an outer race member 168 mounted in an inner cylindrical wall 162 of the casting 78. The control support 120, carrying the vanes 114, has a sealing portion 170 which projects into a recess 160 of the casting 78 to form with an outer cylindrical casting wall 164 a dust seal for the bearing assembly 76 (Figure 6).
