Abstract: 697,834. Jib cranes. SLATER. A. Nov. 20, 1951. [Dec. 12, 1950] No. 27176/.51. Classes 78 (iv) and 78 (v). Hauling means on a ship comprises a samson post at each end, a boom pivotally mounted on each post, a cable between each post and between each boom respectively and a number of separate hoists suspended from the booms and cables. A samson post 6, 7 is supported at each end of the ship and steadied by stays 8. A boom 10, 11 is pivoted to each post and a cable 13  extends from the top of the boom round upper and lower pulleys on the post to the top of which it is anchored, the cable controlling the swing of the boom. The boom is also connected by a cable 15 and tie brace guy to the deck. A cable 22 extends between the booms and has plates 30 interposed along its length. A cable 25 extends between the masts and has interposed spacer plates 31. A winch 33 at either end has four drums 33a, 38, 46 and 46a for operating the coactive cables of four hoisting hooks 35, 44. A cable 32 passes from a drum 33a over a pulley 34 at the top of the boom to a hook 35 and another coactive cable 36 passes from the hook over a pulley 37 on a plate 31 to the adjacent drum 38.

Filed: 1962-07-16
Abstract: A polyether of OH No. 343 is prepared by reacting tris (di-b -hydroxyethylamino) 1:3:5 triazine with propylene oxide, the latter being added in two stages.ALSO:Polyurethanes are prepared by reacting an organic polyisocyanate and a hydroxyl ended polyether of formula <FORM:1049288/C3/1> wherein R, R1, R11, R111, RIV and RV each stand for a hydrogen atom, an alkyl group or a hydroxyl ended polyether chain, at least two of the groups R being hydroxyl ended polyether chains.  The hydroxyl ended polyether may have a M.W. of 300-10,000 and may be the oxyalkylation product of a hydroxy alkyl derivative of melamine.  In the preparation of foams, surface coatings and adhesives the hydroxy ended polyether preferably contains at least three isocyanate reactive groupings. In an example a polyether of OH No. 343 was prepared from tris(di-b -hydroxyethylamino)-1:3:5-triazine and propylene oxide, the latter being added in two stages.  The polyether was mixed with water, butylated urea formaldehyde, cyclohexanone, methyl isobutyl ketone and a solution of a phosgenated crude diaminodiphenylmethane to obtain a coating solution.ALSO:Substrates e.g. wood, rubber, metals, glass and fabrics are coated with a polyurethane coating composition obtained by reacting an organic polyisocyanate with a polyether of formula <FORM:1049288/B1-B2/1> where the groups R each stand for hydrogen, alkyl or a hydroxyl ended polyether chain, at least two of the groups R being hydroxyl ended polyether chains.  In an example a polyurethane obtained from propoxylated tris (di-b hydroxyethylamino) - 1 : 3 : 5 triazine by reaction with a phosgenated crude diamino diphenylmethane in admixture with water, xylene, cyclhexanone, methyl isobutyl ketone, and butylated urea formaldehyde was applied by spinning to steel panels or by dipping to steel rods and dried.

The compound is mixed with a diluent, e.g. naphtha, kerosene, toluene, carbon tetrachloride, chloroform, benzene or 2-ethyl-hexanol, to which either tributyl phosphate or isodecanol is added as an emulsion inhibitor. The cobalt-loaded organic phase is separated from the aqueous phase and scrubbed with a cobaltic ammine sulphate in ammoniacal solution to remove occluded nickel before being stripped with 1-5N sulphuric, nitric or hydrochloric acid to produce a cobalt salt. The nickel is recovered from the original raffinate by crystallization.

In a wrapping-machine in which articles are pushed into pockets arranged in opposed relationship in an intermittently movable wheel and in which wrappers are fed across the path of movement of the articles to be carried by them into the pocket, each pocket having a movable end wall, the walls are separately mounted for sliding movement, one wall ejecting a partially wrapped article from its pocket while the other wall is moved inwardly by an article fed into the opposing pocket by a feed pusher, the end wall at the delivery station moving independently and in advance of the feed pusher. The wrapping wheel is rotated through 180 degrees before the next operation begins. A wrapping wheel 11 consists of a pair of spaced discs 12 driven intermittently in 180 degree steps connected by. upper and lower pocket walls 18. Sliding in slots 21 in the two discs are plates 22, 23 to which are secured the end walls 26, 27. Protruding through the slots is a plate 24 which has extensions 28 for engagement with pushers 29 on reciprocating carriages 31. Articles to be packaged, e.g. batches of tea are positioned against a stop 44 by a conveyer 43 and each batch is moved transversely by a pusher 46 (Fig. 4) into a pocket of the wheel 11, a wrapper 47 being fed across the path of movement. The end wall 26 is pushed by the batch into the pocket, the wrapper 47 being folded about the forward face and tucks being formed by extensions 48 on side guides 49. The wheel is then rotated through 180 degrees and as it comes to rest, the pushers 29 engage with the extensions 28 and push the plate 24 and the end wall 27 (Fig. 4) along the slots to discharge the batch the trailing portion 53 of the wrapper being folded over the top of the batch and the forward portions being folded by tuckers 54. The final folding operations are completed in known manner along the tube 52, the longitudinal seam being sealed by a heater bar 56 and the side folds by heater plates (not shown). The movement of the plate 24 is greater than the length of the batch to allow it to pass into the delivery channel by a distance greater than its length to allow for expansion after retraction of the pusher, Fig. 5. The wall 27 is retracted to clear the delivery channel by spring-biased plungers 59. The pushers 46 and 29 are timed so that the wall 27 moves a distance somewhat greater than the excess distance before the movement of the pusher 46 begins thus leaving a gap 57, Fig. 4, to allow for the retraction of the wall 27.
