Filed: 1971-07-01
Abstract: 1326464 Potting appliances M LOTVEIT and E JENSEN 1 July 1971 [1 July 1970] 30922/71 Heading A1E In a potting machine a plant is supported with its roots in a potting chamber, a measured quantity of potting material is supplied to the chamber and is then compacted around the roots into a plug, and finally the plant is ejected from the chamber and the plug is inserted into a plastic bag or other container. The plant is supported horizontally in a slot 18 of a piston plate Fl so that its roots are wthin a chamber 30 bounded at one end by the piston plate F1, at the opposite end by closure plates E11, E22 movable horizontally by pistons El, E2, and at the sides by pressure plates D11, D22. A well 12 provided with a guide 13 is filled with a supply of potting material, plates B11, B22 initially preventing entry of the material into the potting chamber 30. Plates All, A22 are then slid by pneumatic pistons Al, A2 into abutment with the guide 13, and plates B11, B22 slid apart to release the material between themselves and plates All, A22 into the potting chamber 30. Top closure plates C11, C22 are then brought into abutment by pistons Cl, C2 to close the top of the potting chamber 30, and pressure plates D11, D22 moved together a predetermined distance to compress the potting material a desired amount. A plastic bag 42 is placed over flanges 25 of the closure plates E11, E22, and these are now moved apart, opening the bag and providing an aperture 16 through which the plant is ejected by the piston plate Fl and its plug inserted into the plastic bag. Flexible strips 21 attached to the piston plate Fl protect the exposed parts of the plant during this operation. As a modification the piston plate Fl may be moved forwardly for some distance before the closure plates E11, E22 are open in order to compress the plug of potting material longitudinally. The pistons may be hydraulically actuated instead of pneumatically; alternatively mechanical or electric driving means may be employed.

Title: Antenna assembly
IPC: A01J7/02
Filed: 1950-12-29
Abstract: 680,512. Aerials. STANDARD TELEPHONES & CABLES, Ltd. Dec. 29, 1950 [Jan. 12, 1950], No. 31584/50. Addition to 677,860. Class 40 (vii). The invention relates to an antenna system producing a rotary cardioid pattern by the use of a stationary aerial having an omnidirectional pattern and a rotating directive aerial having a figure-ofeight pattern. In such a system the figure-of-eight aerial is of small length relative to half a wavelength at the operating frequency and is enclosed in a resonator open to radiation about one periphery and the omnidirectional aerial is mounted symmetrically about the directive aerial. The directive aerial may be a folded dipole 1, a tenth of a wavelength long fed from coaxial line 4 through a rotary joint 3 and feeder 2. The dipole may be rotated at 1800 r.p.m. by means not shown. Plates 5 and 6 spaced apart by a distance slightly greater than #/2 are arranged above and below the dipole 1 and joined by a circle of rods 7 which ensure that only horizontally polarized energy passes and assists to match the impedance of the short dipole to free space. As the plates 5 and 6 and rods 7 are not adequate to completely match the dipole an inner circle of rods 8 is also provided. An adjustable plate 9 is mounted on the rods 8 and placed to compensate for the capacitive reactance of the dipole. Any slight remaining mismatch may be compensated for by a matching impedance bridged on the feeder and housed, for example, in rotary coupling 3. The omnidirectional aerial may be placed in any suitable position surrounding the dipole, but in order that the energy radiated may be solely horizontally polarized is preferably placed inside the rods 7. For example, some of the rods 8, e.g. those marked 10, 11, 12 and 13 may be hollow and act as extensions of coaxial feeders 18, 19, 20 and 21 which join in main feeder 22 and serve to feed, in phase, radiators 14, 15, 16 and 17 extending from the respective hollow rods to an adjacent rod 8. It is explained with reference to Figs. 4, 5 and 6 (not shown) that the cage resonator 5, 6, 7 does not entirely prevent the radiation of vertically polarized energy but that if the rods 7 be extended above plate 6 as by extensions 30 to a further plate 28 and preferably also below plate 5 by extensions 29 to a plate 27 vertically polarized signals may be reduced to negligible strength. As shown in Fig. 7, the rods 7 may be replaced by a cylinder of sheet metal 31 with slots 34 replacing the gaps between the rods; the extension rods 29 and 30 may also be replaced by extensions of this cylinder, no slots being required. The inner rods may be replaced by a further slotted cylinder 37 inside which a shorting plunger 39 replacing plate 9 may be adjusted. The omnidirectional antenna may be formed by conductors bridged across certain of the slots 38 in cylinder 37.

Walls.-Relates to means for securing wall blocks or tiles to furnace water-wall tubes, the holding members being separate both from the tubes and from the tiles. In one form, Figs. 1 and 2, two pairs of holding members 28 are employed for each tile. Each element of a pair comprises a toe portion 30 bearing on the tube, a hook portion 29 engaging an undercut projection 26 at the back of the tile and an arm portion carrying a tightening screw 31 adapted to bear on the back of the tile. On tightening the screws 31 against the tile the resultant pressure exercised about the two fulcrums 30 draws the tile tight against the tubes. Shoulders 32 prevent tha two holding members from separating. In the other form. Figs. 3 and 4, there is a pair of holding members 52 for each tile, but each member carries two tightening screws 53 each bearing on one of the tubes and is formed with two hook portions 54. The undercut rug 49 occupies only the middle of the length of the tile and engagement and disengagement of the holding members is then effected by sliding them along the tubes. In both forms the abutting edges of the lugs are bevelled for the reception of jointing cement.
