Patent GB-588717-A (GB)
Title: Improvements in or relating to the preparation of lead salts of phthalic acid
IPC: C07C51/41
Filed: 1944-09-11
Abstract: Lead phthalates are made by reacting phthalic acid or anhydride with lead monoxide in the presence of water.  A solution of phthalic acid or anhydride may be added to a hot suspension of lead monoxide in water at a rate slightly slower than the reaction rate.  A temperature range of between 15 DEG  and 100 DEG C. and preferably 75 DEG  to 95 DEG C. is used.  When the pH of the reaction mixture drops from 9.2 to 8.5, dibasic lead phthalate hemihydrate, 2PbOC6H4(COO)2Pb 1/2 H2O, is separable; a further drop to 6.5 indicates the formation of monobasic lead phthalate, PbOC6H4 (COO)2Pb and a further drop to 5.1 indicates normal lead phthalate, C6H4(COO)2Pb.  The basic phthalates are suitable for use as pigments.  A catalyst such as nitric or formic acid may be used if desired in amounts between 0.10 and 0.15 pounds per 100 pounds of lead monoxide.

Filed: 1957-06-01
Abstract: 896,850. Cooling systems and radiators for internal combustion engines. LEYLAND MOTORS Ltd. Sept. 1, 1958 [June 1, 1957], No. 17465/57. Class 64(3) In an engine cooling system, particularly in vehicles in which the engine is placed beneath the floor of the vehicle, loss of coolant due to expansion is minimized by the provision of an overflow collector tank 7 connected by a flow channel, e.g. pipe 17 and passage 14 to the outward side of a partition 8 provided in the radiator filler cup 2, the partition embodying outwardly and inwardly opening valve members 12, 13 respectively. The overflow tank and filler cup may be entirely separate from the radiator 4 as shown or they may be incorporated in the radiator structure. In the system shown, expansion of engine coolant sufficient to fill the filler tube 1 and cup 2 up to the partition 8 will open the spring-loaded valve 12 and water will flow through 14 and 17 to the overflow tank 7 in which also steam will in part condense and in part escape through vent pipe 18. The radiator vent is connected to the filler cup 2 beneath the partition 8 through a pipe 15 and passage 16. If the pressure in the system falls on cooling to below atmosphere, the inlet valve 13 in the filler cup will open and coolant will be sucked back through 17 and 14 into the circulation system.

Title: Improvements in or relating to photoelectric cells
IPC: H01J40/16
Filed: 1940-12-13
Abstract: 573,173. Photo electric cells. BLACKMAN, W., CINEMA-TELEVISION, Ltd., and TOMES, G. A. R. Dec. 13, 1940, No. 17637. [Class 39 (i)] A circuit comprises a photoelectric cell in which two electrodes are provided in addition to the cathode 9, the first being formed by an evaporating cup 5 located symmetrically in the envelope and maintained at a negative potential relative to the cathode, whilst the second,' which in the cell shown is formed as a cylindrical member 10, acts as a collector electrode. The sensitivity of the cell increases continuously with increase in voltage on the collector electrode, which may be maintained at zero to 100 volts positive with respect to the cathode, whilst the electrode 5 is at minus 7.5 volts. The cell may be manufactured as described in Specification 541,794, the member 10 being used as a shield during evaporation of the cathode material from the cup 5 to protect the cylindrical part of the envelope wall from deposition and being subsequently moved to the lower position shown. Photo or secondary emission from elements of the cell other than the cathode may be avoided by positioning them so as to receive a minimum of reflected light from the cathode, or by a suitable coating applied to them ; alternatively in some cases an improved voltage-current characteristic is obtained by allowing a small amount of uncontrolled photo-emission to occur, for which purpose the other elements may be made emissive to a desired degree by a caesiated coating. A conductive coating may be applied to the part of the envelope surrounding the pinch and depositing cups and maintained at a suitable potential to prevent charging of the wall.
