IPC: B01J19/24
Filed: 1963-09-26
Abstract: Low M.W. polyesters or copolyesters are continuously produced by ester interchange of at least one ester of a dicarboxylic and a low M.W. alcohol with at least one diol while maintaining a ratio of one mol of said ester of a dicarboxylic acid to more than 2 mols of said diol, in the presence of an ester interchange and a precondensation catalyst and subsequent precondensation in thin layers, the primary ester interchange being carried out in a reaction tube provided with a heating jacket over its whole length, at a temperature below the B.P. of the diol and under a pressure slightly higher than atmospheric pressure in such a way that the average residence time of the ester interchange product in the reaction tube is less than 30 minutes, and the precondensation being subsequently carried out under sub-atmospheric pressure at a temperature above the B.P. of the diol in a falling film evaporator, the residence time of the precondensation product in the falling film evaporator being less than 3 mins. The dicarboxylic acid ester may be an ester of terephthalic acid, isophthalic acid, sebacic acid or adipic acid with an aliphatic alcohol of 1-6 C.  The diol may be ethylene glycol or 1: 4 dimethylol cyclohexane.

Title: Drying of wet solid sodium cyanide
Inventor: HARTERT ERWIN
IPC: F26B3/08
Filed: 1961-10-25
Abstract: Wet solid sodium cyanide may be dried by suspending it in an air stream having a temperature of up to 500 DEG C., e.g. 100 to 200 DEG C.  This process may be carried out in an air suspension drier, flash drier or fluidized bed.  The wet solid is fed to a fluidized bed of solid sodium cyanide of water content below 0,5%.  The drying air is free from CO2 and after passage through the bed, has entrained dust removed in a cyclone.  The air is then recycled after washing with aqueous 30-50% NaOH, to remove water vapour and reheating. Specifications 802,091 and 834,765 are referred to.

Title: Motor vehicle radio receiver antenna arrangements
IPC: H01Q1/12
Filed: 1973-08-16
Abstract: 1393317 Aerials GENERAL MOTORS CORP 16 Aug 1973 [1 Sept 1972] 38678/73 Heading H4A A motor vehicle aerial arrangement comprises an FM aerial and an AM aerial which are carried by a window of the vehicle, and which are connected to a common terminal on said window. The FM aerial has an effective length which is approximately one quarter of the median wavelength in the FM band, and the AM aerial has an effective length at the frequency corresponding to said median wavelength of approximately one half of said median wavelength. Consequently, the AM aerial exhibits high impedance in the FM band, so reducing interference with the operation of the FM aerial. As described, an aerial arrangement which is disposed on the windscreen 16 of a motor vehicle 10 comprises a central conductor 26 which extends upwardly from a terminal 36, and forms the FM aerial, and four conductors 28, 30, 32, 34 which extend horizontally from the terminal 36 in parallel, oppositely-directed mirror-image pairs 28, 32 and 30, 34. A coaxial cable 44 is connected at one end to the terminal 36 and the body 12 of the vehicle 10, and at the other end to a receiver 38. The windscreen 16 is of laminated construction, and the aerial conductors may be wires embedded in the plastics interlayer and soldered to a metal foil terminal (Fig. 2, not shown). Alternatively, the aerial conductors and the terminal may be made by firing suitably shaped deposits of a pulverulent ceramic-silver mixture on a surface of one of the glass panes of the laminated windscreen (Fig. 3, not shown). In another embodiment, each conductor 28, 30, 32, 34, Fig. 5, is folded back upon itself, to reduce its overall physical length.
