A jib crane, which may be readily coupled to and uncoupled from a truck, is arranged to be mounted on and removed from the truck by means of its hydraulically-actuated boom assembly. As shown, the crane consists of a main boom 2, which is pivotally mounted on a rotatable column in a tubular base member 1, an outer telescopic boom 3, 4, 5, pivotally mounted on the outer end of the boom 2 and connected thereto by an hydraulic ram 6, and an hydraulic ground-engaging support 7, 8. Coupling devices 10, 11, 18 provided on the crane are adapted to engage devices 12, 13, 15 on the truck. In operation, to move the crane from the ground, through the broken-line position to the full-line position, the crane is raised to the broken line position by actuation of the support 7, 8 and of the jib, the outer end of which engages the ground. The crane is then propped in this position and the hollow outer end of the jib is engaged with a bolt 17 pivotally mounted on the truck frame. By pivoting and telescopically retracting the boom sections 2, 3 and 4, 5 the crane pulls itself on to the truck to engage the coupling devices.

Abstract: 1,229,489. Pressure vessel closures. N. H. KEMP. 3 May, 1968, No. 21050/68. Heading F2P. A closure for an opening in a pressure vessel or other container comprises a cap 8 having a sealing ring 16, which is located in a recess 22 on the inside of a peripheral skirt portion 8a of the cap for axial sliding movement relative to the cap when the latter is attached to the opening. Fluid pressure within the vessel acts to urge the limbs 17 and 19 of the ring, which is L-shaped, against the base of the recess and the surface 20 about the opening respectively. As described, the limb 19 engages the end face of a flanged stand-pipe 4 of a tank, Fig. 1 (not shown), the cap being secured to the stand-pipe by two opposed pairs of hooked levers 12 which are pivoted to cap lugs 11 and which are locked with their free ends under the stand-pipe flange by pins 15a extending through the lever ends and ears 15 on the cap. Alternatively, the closure may be secured over an opening in the wall of a vessel by cables or wires attached to the cap and extending around the vessel, the cap and ring being shaped to conform to the vessel wall about the opening. The sealing ring may be of neoprene, polytetrafluorethylene, aluminium or asbestos, and the ring limb 19 may be stiffer than the limb 17.

An expansion valve is controlled by a temperature screw located at the outlet of an evaporator containing a thermally conducting gauze insert which occupies only a minor part of the evaporator flow cross-section and which lies against the wall of the evaporator passage. Wetting of the wall is promoted, thereby rendering the performance of the evaporator more predictable so that the chances of liquid refrigerant leaving the evaporator are reduced. The insert may have a longitudinally extending gap which allows the accumulation of excess liquid.

The reaction is generally carried out in the presence of an alkaline transesterification catalyst, e.g. an alkali metal hydroxide, alcoholate or phenolate. The non-azeotropic solvent is suitably one boiling between 120 and 160 C. and specified solvents are xylenes, ethylbenzene, chlorobenzene and cumene. Examples are given for the production of diallyl- and dimethallyl phosphonates and comparative examples are also given in which (1) diethyl phosponate is used instead of dimethyl phosphonate under the conditions of the invention, (2) the reaction between dimethyl phosphonate and allyl alcohol is carried out using toluene as solvent (the toluene forming an azeotrope with methanol), and (3) the reaction with dimethyl phosphonate is carried out without a non-azeotropic solvent but with an excess of allyl alcohol, a reduced conversion to diallyl phosphonate being obtained in each case.

In the embodiment illustrated both rollers have the above described construction and house a U. V. lamp 37, mounted on a T-shaped cantilevered support assembly 35, within the inner core 31. The lamp is enclosed by a reflector 43, shields 45 and a baffle or fibre optic plate 47 which combine to direct the U. V. light substantially perpendicular to the surface of the workpiece. The lamps 37 are each surrounded by a water jacket 41 which absorbs infrared radiation, the water containing a chemical e. g. cupric or cobalt sulphate, and/or the jacket comprising tinted glass to absorb visible radiation. The support 35 also supports an air transfer block 113 inter-connecting an air-pressure source, (not shown) and the enclosed space via an aperture 137 in the core wall. Deformation rollers 143 are provided around the periphery of the walls 33 to increase the deformation of the walls adjacent the workpiece. The rollers are cooled by filtered air drawn into the housing 17 by fans and passed along the interior of the cores 31 and back along the outer surface of walls 33 to be finally exhausted via the workpiece inlet and outlet. One roller is driven by gearing mounted at one end thereof, the other roller either being friction driven or including a gear inter-meshing with the aforesaid gearing.

The load-engaging platform 268 of the crane can be moved fore and aft as well as laterally. Fig. 8 shows one form of conveyer for moving containers in the storage cells. Cams 42d are rotated by links 44, 46 and cables 50, 52 so that a container engaging platform 42c is raised to lift a container from supports in the cell. Further traction on cables 50, 52 causes the conveyer to move on wheels 42b in the appropriate direction. The cables may be replaced by chains driven by sprockets. To avoid duplication of the driving cables or chains, the cams 42d on opposite sides of the conveyer may be linked by a driving shaft 42d<SP>1</SP>, Fig. 13. Fig. 14 shows a chain conveyer 144 which runs in guides 142 in the floor of each cell and supports containers on members 46 which may extend across the conveyer from one side to the other.
