Abstract: 1,144,573. Automatic voltage control. JOSEPH LUCAS (INDUSTRIES) Ltd. Aug. 12, 1966 [Aug. 25, 1965; Jan. 14, 1966], Nos. 36450/65 and 1828/66. Heading G3R. [Also in Division H2] A system for charging the battery 1 of a road vehicle comprises an alternator 11 which, when the speed of the alternator is below a predetermined value and a switch 21 is closed, charges the battery in alternate half cycles over the rectifiers 15, 19 and 16, 18 respectively and when the speed of the alternator is above the predetermined value and the switch 21 is open, charges the battery in alternate half cycles over the rectifiers 15, 17 and 16, 17 respectively. Thus when the alternator speed is above a predetermined value only a part of the alternator winding is used at any one time. Three phase star and delta arrangements are described together with the description of a four phase system. The switch 21 may be speed or current sensitive, either mechanical or electronic, or it may be linked to the throttle of manifold mechanisms. The alternator may have a permanent magnet rotor and the rectifiers 15, 16 may be thyristors the firing of which may be made dependent upon the battery voltage so as to regulate the battery charging rate.

Title: Improvements in method of manufacturing aluminium chloride
IPC: C01F7/58
Filed: 1920-12-30
Abstract: Aluminium chloride is obtained by treating with chlorine a mixture of alumina, carbon, and aluminium without external heating.  The reaction of the chlorine on the aluminium is effected at about 50 DEG C. and generates enough heat to effect the reduction of the alumina by the carbon.  Aluminium dross, which contains both alumina and aluminium, may be employed mixed with carbon, but any deficiency in either of its constituents may be made up by addition of bauxite or aluminium.  The reaction may be effected in an iron retort lined with a mixture of coke dust and pitch or tar and heat-insulated on the outside.  When the materials are charged into a hot retort the proportion of aluminium may be decreased.

Title: Process for the manufacture of condensation products
IPC: C08G63/06
Filed: 1934-12-21
Abstract: Polyhydric alcohols containing at least 3 hydroxyl groups are condensed with citric or tartaric acid under reduced pressure, the reaction being interrupted while at least one carboxylic group per molecule of the acid employed is still present in the free state. When condensing citric acid with sorbitol or mannitol, the condensation is preferably effected so that 1 mol. of water is split off for 1 mol. of the acid used.  The products are acid, soluble in water and may readily be transformed into their salts with alkalis, alkaline earths, magnesium, ammonia or amines, and may be used in the manufacture of medicines.  According to examples: (1) mannitol and citric acid are condensed and the water-soluble product converted into the calcium salt; (2) sorbitol and citric acid are condensed so as to esterify one carboxylic group and the product converted into the calcium, barium magnesium, ammonium or diethylamine salts.
