Abstract: 1,271,605. Tipping and discharging opentopped containers. LAFARGE CANADA Ltd. 21 Jan., 1970 [19 Feb., 1969], No. 2919/70. Heading B8E. To discharge an open-topped container, e.g. an oil drum 74, Fig. 5, a bucket 5 suspended by a frame 2 is lowered over the container and a handle 66, Fig. 1, is moved upwards to release a stop 70 so that the frame 2 is free to pivot. This movement of the handle 66 also looks a pair of doors 8, 10, Fig. 3 (not shown), in the closed position. The frame 2 is now lowered until it is below gravity-operated catches 58, 60, Fig. 8, and subsequently raised, when, by abutting the catch 60, the frame tips the bucket and the container 74 into the position shown in Fig. 8. The frame is now raised vertically and the bucket swings into a vertical position in which it is transported to the discharge station. As the bucket is lowered a rod 64 attached to the handle 66 is pushed inwards to release the door catch. The doors 8, 10 are now manually or automatically opened to discharge the contents of the drum, some of which are already in the bucket. The frame 2 is next lowered below the catches 60, 58 and raised again to tip the empty bucket to the position shown in Fig. 11. From this position the frame is lowered to its original position and locked there by engagement with a spring catch attached to the handle 66. The cycle of operations is now complete.

Title: Improvements relating to currentless nickel plating baths
IPC: C23C18/34
Filed: 1962-01-26
Abstract: A concentrate for making or regenerating a non-electrolytic nickel plating bath comprising a solution of a water-soluble nickel salt and a water-soluble reducing agent in a solvent mixture comprising a water-soluble diamine, a water-soluble polyhydric alcohol and a water-soluble tertiary alkanolamine.  The reducing agent is preferably hypophosphorus acid.  The nickel salt can be any water-soluble nickel salt of an inorganic or organic acid, but is preferably a salt of an organic acid, e.g. nickel acetate. The diamine is an aromatic 1,2-diamine or an aliphatic 1,2-, 1,3-, or 1,4-diamine.  The polyhydric alcohol is a pentitol, hexitol, or glycol, or glycerine, erythritol or pentaerythritol but is preferably sorbitol.  The tertiary alkanolamine is triethanolamine.  The nickel salt is dissolved in a mixture of diamine and polyhydric alcohol such that the molecular ratio is 1:2:0.5.  The hypophosphorus acid and tertiary alkanolamine form a further solution in a molecular ratio of 1:1; and the two solutions are then mixed so that the concentrate obtained contains 1.5-3.5 mols of reducing acid per mol of nickel salt, and preferably 2 mols.  The bath is prepared by dilution of the concentrate with 3-5 volumes of water.  In an example a solution is prepared from 234 gms. of nickel acetate, 100 gms. of sorbitol and 120 gms. of ethylene diamine and mixed with a solution of 304 gms. of triethanolamine and 132 gms. of 100% hypophosphorus acid; and the concentrate contains about 100-110 gms. of nickel per litre.

Framework.-Spars, girders, longerons, intercostals, and similar aircraft members comprise girder elements suitable to resist bending-stresses, and other elements of tubular or other form suitable to resist end thrust, torque, or other stresses, so arranged that the girder elements take up only the bending-stresses and wholly relieve the tubular or other elements of bending-stresses and the deformation incidental thereto. The Figure shows a metal aeroplane spar comprising girder elements g carrying the former ribs r to which the aerofoil skin is attached, and hung on to the main joint blocks J by bolts b, the bolt-holes being horizontally elongated. Tubular members t are flanged and bolted to the blocks J, but are not connected intermediately with the girder elements g. The elements g thus take the bending- stress due to the loading of the ribs r, and the members t are not subject to such stress, but take wholly the end thrust and torque imposed by the interspar strut and 'bracing members s, c, al, l, i, d connected to the joint blocks.

According to the invention, a projectile loading hollow plunger 1 is arranged in combination with the piston 2 connected by a link 6 to a cocking lever 3, 11 so that the plunger performs a short stroke independent of the piston to allow a projectile to drop from a magazine 8 into the barrel chamber. When the piston is pulled back by the link 6 and the cocking lever and brought into engagement with a sear 5, another link 4 connecting the cocking lever to the plunger gives a short backward stroke to the plunger to allow the projectile to fall into the barrel chamber ; and when the cocking lever is returned forward, the piston remains cocked but the plunger returns forward, and a tubular extension b thereon pushes the projectile into the barrel. The cocking lever has a handle part 3 pivoted to a lower part 11 enabling the handle to be swung down laterally to lock the lever in the forward position. A spring catch serves to hold the handle in either position relatively to the lower part 11. The magazine is provided with a hinged cover 9.
