Abstract: An aerial plug socket for high-frequency ranges has a metal base, which carries the coaxial plug elements for plugging-in the connection cables, and clamping devices arranged on the base, on the one hand for the inner conductor, and on the other for the outer conductor of each coaxial cable leading into the socket. The clamping system, in the case of the outer conductor, consists of a metal clamping arm pivotally arranged in front of the inner conductor clamping device, one clamping surface of the arm lying against the outer conductor and a metal clamping support facing the opposite clamping surface, whereby the clamping surface and clamping support hold the outer conductor in the operating position and grip it tightly. The clamping arm (15) is pivotally arranged around an axis (19) which seen from the insertion direction lies behind the inner conductor-clamping device (6, 13), and transversely to the connection cable longitudinal axis (19). The arm (15) is furthermore mounted on the base carrier (1) in lateral slideways (17) so as to move perpendicularly to the longitudinal axis of the connection cable, its upward movement being limited by stops, and it can be screwed into the operating position against the outer conductor.

Title: Melamine is prepared from urea in a high pressure process
Inventor: TJIOE TJAY TJIEN
IPC: C07D251/60
Filed: 1997-06-02
Granted: 1998-12-03
Abstract: A method for preparing melamine from urea via a high-pressure process is claimed in which solid melamine is obtained. The melamine melt coming from the reactor is transferred to a vessel where it is cooled with an evaporating cooling medium. The melamine melt has a temperature of between its m.pt. and 450 deg C and is sprayed and cooled by means of an evaporating cooling medium via spraying means within a vessel into an ammonia environment at an increased ammonia pressure. The melamine melt is converted to melamine powder and direct or indirect cooling is employed to yield a powder having a temperature of up to 270 deg C. Ammonia pressure is then released and the melamine powder is cooled, over at least part of the cooling range by mechanical agitation of the powder with direct or indirect cooling.
