Patent GB-2215930-A (GB)
Title: Sub-carrier reception
Inventor: HAWKES HENRY WILLIAM
IPC: H03D1/06
Filed: 1988-03-15
Abstract: A method of low-noise reception of a signal comprising a carrier and at least one sideband produced by at least one sub-carrier. The carrier is extracted using a phaselock loop 6 and multiplied with the received signal in a circuit 8 with both in the same phase. The products are filtered by band-pass filters 10-12 of bandwidth equal to the desired noise bandwidth and each centred on a sub-carrier frequency. The filtered components may be processed in different ways depending on the requirement, eg the original received signal can be reconstituted, but with reduced noise content, by multiplying each filtered component with the extracted carrier in circuits 14-16 and added to the extracted carrier in adder 17 for subsequent conventional detection. Alternatively, each filtered component can be detected or processed separately in circuits 18-20 and these outputs added if desired. Phase-shifters 22-24 and attenuator/amplifiers 25-27 can be used to compensate for differential dispersion effects. Amplitude- and phase-modulated signals can be handled, and both symmetrical and assymetrical sideband structures, by suitable modifications. <IMAGE>

Title: Door sealing means
Inventor: SMITH GEOFFREY FREDERICK
IPC: E06B7/215
Filed: 1989-06-14
Abstract: A mechanical device for closing the gap between a door and its threshold comprises a mounting member 1 attached to the lower end of the door D and pivotally supporting a sealing member 3 in the space beneath the undersurface of the door. The sealing member carries a sealing strip 5 at its forward end and springs 6 act on its rearward end tending to pivot the strip 5 up out of contact with the floor (when the door is open as shown). When the door is closed, an actuating pin extending transversely from the rearward end of the sealing member runs up a ramp surface on an associated striker to pivot the sealing strip 5 down into contact with the threshold. In this way, the gap beneath the door can be effectively closed by means hidden from view and which do not require any elements to be mounted on the threshold itself which could act as obstacles e.g. to the passage of wheelchairs. <IMAGE>
