Inking-apparatus.-Printer' rollers are made of a composition containing gelatine &c. rendered infusible by the addition of a pentose such as arabinose or xylose, for the purpose of producing furfuraldehyde in situ. The syrup obtained by hydrolysis of a pentosan may be used directly, and in some cases, a pentosan itself. Several examples are given in the Specification of which the following is typical, light magnesia 37 per cent, wood pulp 1 per cent, glycerine 37 per cent, soaked glue 25 per cent., to which mixture is added 2.5 per cent arabinose syrup (75-80 per cent). Dry glue is soaked in cold water until it has taken up half its weight, and is then liquefied by heat. The mineral matter and fibrous material are separately ground with portions of the glycerine and the mixtures are added to the glue. The mixture is heated, arabinose syrup is added, and the composition is run into moulds and heated until it becomes infusible. If desired, hydrochloric acid may be added to facilitate formation of the aldehvde. Other filling materials mentioned are magnesium carbonate, chalk, alumina, zinc oxide, calcium sulphate.

Jointing by forging; stamping.-A machine for manufacturing containers of the type comprising a base and approximately cylindrical side-wall portion which is inserted and clamped in a groove in the base is characterized in that the machine performs both the setting and the final shaping of the side wall portion and comprises a mould, a setting piston movable axially in relation to the mould and an expansible bladder surrounding the piston the bladder being filled with liquid and adapted after movement of the piston for the setting operation to be expanded by high internal pressure for final shaping of the side-wall portion into conformity with the mould. The base 1 and side-wall portion 2 of the container are inserted in a mould 4. One end of the mould is closed by a pivoted cylinder head 5 locked by a latch 7. A rigid setting piston 8 projects into the mould, said piston having an enlarged head 19 for engaging the base 1 inside a circular axiallyinclined groove 3 in the base for receiving the side-wall portion 2 of the container. The piston 8 is surrounded by a flexible bladder 9, e.g. of rubber connected by conduits 11 to a source of fluid pressure 10 and secured to the piston by bands 12 and 13, the band 13 being outside the bladder and surrounded by a hard rubber collar 14. One end of the collar 14 seats in a groove 15 provided in a guide shoulder 20 of the piston, the outer edge 18 of the groove being thin and flexible and capable of being pressed into engagement with the wall of the mould. An hydraulic jack 16 acts on the setting piston 8 and a yoke 23 connected to the mould by studs 24. Actuation of the jack causes the mould to move relative to the setting piston and the return movement is effected by a spring 17. In operation the container parts are assembled in the mould and the bladder is inflated with a preparatory pressure to expel air from inside the container through a passageway 25. After the setting operation in which the channel 3 in the base 1 is flattened against the side-wall portion 2 the pressure inside the bladder is increased to effect the final moulding of the container. After moulding, the pressure in the bladder and the pressure on the jack 16 is relieved, and the spring 17 moves the piston away from the container base to enable the cylinder head 5 to be opened and the finished container removed from the mould. The jack 16 may be actuated to facilitate and accelerate this extraction. Specification 725,854 is referred to.
