[Also in Group XXIX] A building, e.g. a large metal tank, is erected ring by ring by hydraulic or screw lifting jacks 4, inserted and attached at the top or acting near the top of the first ring and so that operation cause the jacks and attached ring to climb up their long ram rods 15 the first assembled ring being lifted the height of the plates of one ring so that the plates of the second ring can be welded to the bottom edge of the raised first ring to hang freely therefrom. In Fig. 1, a roof 3 is assembled on wall plates 2 at ground level. Four jacks 4 are then attached to the ring of wall plates 2 and are coupled to a central pump 5. The jacks are supported on legs 25 connected to a base plate, and they are steadied by inclined optional stays 26. In Figs. 1 and 2, the jacks 4 are attached to the roof 3 which has been assembled on the first ring 2 of wall plates assembled on the welded bottom plates 1 of the base. The jacks have long ram thrust rods 15 which are stiffened by being guided through U-shaped fittings 29 welded at spaced intervals to the inner wall 2. The rods 15 also reach down through the tube or angle 25, Fig. 2, of a trestle 25-26 resting on the base. The thrust rods 15 are replaceable by longer rods as the height of the tank or building proceeds. Thereby the roof and attached depending ring walls are lifted as a whole to the height for welding on another ring wall and so on. When a new ring of wall plates 2 is being assembled the plates of the wall may be gripped in the jaws of a clamp 38, Fig. 6, which can slide up on the angular post 25 of a steadying trestle 25, 26, several trestles being located round the periphery.

A pneumatic jack for moving a coal face conveyer has means for limiting the stroke of the piston comprising a ratchet-toothed bar 7 movable with the piston and a'stop 10 forming part of a bar guide 9 secured to the cylinder. The bar 7 has a slot 12 which is loosely mounted on a rod 6 extending laterally from the pistonrod 3, a spring (not shown) being provided to move the bar towards the conveyer 4 by the length of the slot when the bar is disengaged from the stop 10 by lifting its free end. This ensures that, when re-lowered, the bar does not return to a locking position until the piston-rod together with the conveyer has been moved forward a distance corresponding to the tooth pitch of the bar. An adjustable roof engaging strut 2 pivoted to the cylinder acts as a reaction member, but in a modification (not shown) the strut is pivoted on the piston-rod whilst the conveyer 4 is pivoted to the cylinder. In another modification (Figs. 3-5, not shown) a pair of inter-connected jacks have a single stroke limiting bar and stop mechanism arranged in the space between them. In further modifications (also not shown) a toothed bar rigid with the piston-rod co-operates with a pawl pivoted on the guide 9 ; or a pair of bar and stop mechanisms are provided on each side of the jack cylinder ; or the bar is mounted on the cylinder and the stop is mounted on the pistonrod. The bar may be provided with another set of teeth of different pitch on its upper edge and may be rotated about its longitudinal axis so that either set is engaged with the stop; alternatively more than one bar may be provided.
Patent GB-742534-A (GB)
Title: Solid shaped detergent compositions
IPC: C11D10/04
Filed: 1952-11-26
Abstract: In the shaped detergent compositions of the parent Specification, a part or the whole of the ester of orthophosphoric acid or salt of such ester is replaced by a phosphonic acid containing a hydrocarbon radical having at least 4 carbon atoms linked directly to the phosphorus atom of the phosphonic acid, or by a partial ester of such a phosphonic acid or by a compound in which a phosphonic acid complete ester group and a phosphonic acid partial ester group are linked at their phosphorus atoms by a polymethylene group, said phosphonic acid or derivative being preferably in the form of an alkali metal, ammonium or amine salt. The hydrocarbon radical may be alkyl, aryl, aralkyl, alkyl-aryl or cycloaliphatic and may carry substituents such as amino, alkylamino, amido, nitro, alkyl or hydroxyalkyl groups or halogen atoms.  The hydrocarbon radical of the partial ester may be similar to that of the phosphonic acid.  The compositions may also contain soaps, sulphonated soap-forming fatty acids, synthetic detergents such as ethylene oxide condensation products sodium chloride, sodium silicate, aluminium silicates, urea-formaldehyde condensation products, polyvinyl alcohol, alginates, sodium methacrylate, inorganic phosphates, wool fat products and lethicin.  It is advantageous to adjust the pH value of the compositions to a neutral or slightly acid reaction.  In the first example, to a mixture of 15 per cent of coconut oil fatty acids, 60 of lard oil fatty acids and 5 of oleic acid is added 20 per cent of a surface-active phosphonic acid derivative of the formula C17 H35 CO. NH. C6H4. PO. (OH)2, obtained by reacting 1 mol. of stearyl chloride with 1 mol. of amino-phenyl phosphonic acid, and the mixture is neutralized with caustic soda.  In the second example 25 parts of octadecyl dihydrogen orthophosphate, 25 parts of octadecyl tetraglycol dihydrogen, orthophosphate and 40 parts of the sodium salt of the phosphonic acid derivative of example 1 are mixed with the addition of 10 parts of water, adjusted to pH 6 to 6.5 and compressed into bars.
