Title: Improvements in or relating to the manufacture of aluminium dialkyl monohalides
Inventor: KING RALPH WILLIAM
IPC: C07F5/06
Filed: 1956-04-10
Abstract: In the process for preparing C1-C4 dialkyl aluminium monohalide by reacting aluminium sesquihalide with an alkali metal, 3 to 5 mols. of alkali metal are used for each 10 mols. of aluminium sesquihalide. The preferred alkali metal is sodium.  The dialkyl aluminium monohalide is distilled from the reaction vessel leaving a pyrophoric residue comprising aluminium, sodium chloride and organo-aluminium compounds which, using the proportions of reagents stated above, is fusible and may be drained off.  Alternatively the reactor may be filled with an inert gas and dilute alkali metal hydroxide solution sprayed in to remove the residue.  The alkali metal hydroxide solution is preferably at about 90 DEG  C.  If desired, the aluminium in the residue may be allowed to settle prior to draining off so that it is available for forming the next batch of sesquihalide.  The examples describe the process as applied to the preparation of diethyl aluminium monochloride.

Title: Improvements in or relating to percussive apparatus
IPC: E02D7/12
Filed: 1937-04-16
Abstract: 493,720. Percussive tools; pile-drivers. DOUGLAS, F. L. April 16, 1937, No. 10942. [Class 124] [Also in Group XXII] Relates to pile-drivers of the kind comprising a movable cylinder and a single acting piston operated on the compression ignition principle upon a charge of oil being injected into said cylinder by an injection pump actuated by the relative movement between the cylinder and piston, the piston rod of the latter resting upon or being connected to an anvil which rests upon the pile to be driven and to which anvil blows are given by the cylinder. According to the invention, the cylinder is ported to provide air inlet and exhaust ports controlled by the relative movement of the piston and cylinder. As shown, the piston rod 2 has a foot 3 adapted to rest on the pile. The cylinder has a compression chamber 5, combustion chamber 6, ports 8, 9, connected by a duct 7 and exhaust ports 10. The cylinder head has a fuel injection nozzle 12 connected to a pump 13 which receives oil from a reservoir 15. The pump 13 is actuated upon each downward movement of the cylinder 4 by a tappet rod 17 which coacts with an abutment 19 pivoted to the foot 3. In operation, a charge is fired in the combustion chamber 6 thus moving the cylinder upwardly and compressing air in the portion 5. When the piston uncovers the ports 9, 10, air passes through the duct 7 from the chamber 5 and the expanded gases escape through the port 10. The cylinder then falls and strikes the foot 3. At the same time the pump 13 is actuated to force a charge of oil into the compressed air in the combustion chamber 6. The pump 13 is rendered inoperative by displacement of the abutment 19.
