Title: Broadband private automatic branch exchange
Inventor: STANNARD RICHARD
IPC: H04M11/00
Filed: 1991-01-31
Abstract: Abstract Broadband Private Automatic Branch Exchange A broadband private automatic branch exchange is to be implemented in which all broadband user stations can be switched like normal telephone terminals with all features of a conventional telephone private  automatic branch exchange  and without  each broadband terminal requiring its own operator position.  To achieve this, in accordance with the invention, all the broadband terminals (BB-E1, BB-E24)  which are connectable via a broadband switching array (BB-V) to the subscriber line unit (TAE) of the public broadband network  (VBN)  are also connected like ordinary telephone user stations to  a narrow band  telephone private automatic branch exchange system  (SB-PABX)  which is connected via a signaling conversion module (VBNA) to the line unit (TAE) and which initiates the narrow band call setup and controls the broadband switching array for switching broadband calls.

Title: Antenna apparatus with reflector or lens consisting of a frequency scanned grating
Inventor: JOHANSSON STEFAN
IPC: H01Q19/06
Filed: 1990-05-10
Abstract: The present invention relates to an antenna apparatus for high frequency applications, essentially composed of feed antenna (15) and reflector (16) or lens (19) consisting of a frequency scanned grating which reflects or transmits the incident electromagnetic field into a diffracted field consisting of the first order diffracted grating-lobe, where the shape of curvature of the reflector or the lens is not directly determined by desired radiation characteristics but can be chosen to obtain other benefits.

Title: Sealing of air heaters by deforming sector plates
Inventor: HAGAR DONALD K
IPC: F28D19/04
Filed: 1990-10-04
Abstract: A sealing structure for an air preheater is provided for maintaining a constant clearance between the drum (48) and deformable sector plates (176). Deflection governing struts or beams (120) extend across the sector plates (176) and bend in a manner which corresponds with the change in shape which the drum (48) undergoes when its temperature changes. The outer ends of the struts are connected to an outer ring (110) engages with the drum via guides (100). As the drum (48) deforms so that its ends assume approximately partial spherical curvatures in response to increased temperatures, the struts (120) are likewise deformed. The deformation of the sector plates (176) is controlled by the more rigid struts (120).
