Filed: 1989-08-10
Abstract: A mechanical seal for sealing a shaft (2), which shaft is guided through a wall (6a) and rotates about the longitudinal axis (1) of said mechanical seal, contains a first ring arrangement (9), which is held in a sealed manner and rotationally fixed on the wall (6a), moves in the axial direction against springs (13) and rests with its sliding surface (21b; 21c) on the sliding surface (15a) of a second ring arrangement (15) which is held in a sealed manner and rotationally fixed on the shaft (2). At least on its sliding surface (15a), the second ring arrangement (15) consists of a material of high wear resistance with a modulus of elasticity of greater than 10 x 10<4> N/mm<2>. The first ring arrangement (9), which is subjected radially externally to the fluid to be sealed, contains an annular body (9b) of a material having good sliding characteristics, with a modulus of elasticity of less than 10 x 10<4> N/mm<2>, on which a sliding surface (21b) is formed. This body (9b) is tensioned between annular parts (9a; 9c), whose modulus of elasticity is greater than 10 x 10<4> N/mm<2> and at least one (9c) of which forms a further annular sliding surface (21c), which directly bounds the sliding surface (21b) of the annular body (9b). In this way, a mechanical seal is produced which has a favourable geometry of the sliding surfaces even at high pressures and temperatures and hence has low leakage values and friction power loss. The said mechanical seal has emergency running characteristics and is suitable for sealing abrasive fluids. <IMAGE>

Title: Phase shift data transfer system for phased array antenna apparatuses
IPC: H01Q3/36
Filed: 1989-08-23
Abstract: A phase shift data transfer system for phased array 
antenna apparatuses having a plurality of antenna elements (1a-i) 
arranged in rows and columns in an X-Y plane. A phase 
shifter (2a-i) is connected to each of the antenna elements. In 
order to form a beam radiating in a desired direction, an 
amount of phase shift is set in each phase shifter as the 
sum of a first component and a second component specified 
by an x coordinate and a y coordinate representative of the 
location of the antenna element to which the phase shifter 
is connected. A computing means computes a first component 
for every x coordinate and a second component for every y 
coordinate. The first component thus computed is trans­
ferred to control circuits (3a-i) of 
the phase shifters (2a-i) corresponding to the x coordi­
nate specifying the first component. The second component 
thus computed is transferred to the control circuits (30-i) of the 
phase shifters (2a-i) corre­
sponding to the y coordinate specifying the second compo­
nent. Each  control circuit (3a-i) of the 
phase shifter (2a-i) adds the first and second 
components thus transferred and sets the sum in the phase 
shifter (2a-i).

client application and the icon's source application are 
automatically terminated. The icon is placed within a 
second client application and communications between the 
second client application and the source application are 
automatically initiated. In the disclosed embodiment of 
the present invention a conversational data structure 
designed to support communication between a client application 
and a source application is automatically created 
in response to an initiate communications message from a 
client application to a source application, after a determination 
has been made that the icon in question is appropriately 
served by the source application. Client applications 
containing multiple icons may be simply and easily 
duplicated by graphically copying each icon and automatically 
initiating communication between the source application 
and the application containing the copied icon.
