IPC: H04B7/185
Filed: 2021-01-29
Abstract: A filter structure (300) has a frame (325) carrying a filter compartment (120T/R) that holds first and second waveguide filters (F1H, F2H; F1L, F2L). The filter compartment (120T/R) is rotatable (R) a predetermined angle around a rotation axis (AV) relative to the frame (325) so as to either engage the first waveguide filter (F1H, F2H) or the second waveguide filter (F1L, F2L) in a waveguide conduit (121; 122), thus rendering the waveguide conduit adapted for forwarding radio-frequency signals at a higher band or a lower band respectively. Consequently, the filter structure (300) is suitable for inclusion in a dual-band radio terminal for communication with spacecrafts via an antenna unit exchanging radio-frequency signals bidirectionally with the spacecrafts.

Patent SE-507806-C2 (SE)
Inventor: CLARKSON CURTIS W
IPC: F16K35/10
Filed: 1992-08-04
Abstract: A packingless gate valve is disclosed which includes a housing having opposed similar housing halves with resilient sleeve units which compressibly engage each other in the valve open condition and engage opposite sides of the gate in the valve closed condition. Each sleeve unit has a plurality of compression holes extending axially and arranged at intervals relative to the circumference of the sleeve. An encircling stiffening ring of harder material is encapsulated in each sleeve so as to be positioned at the inner end of the compression holes. The compression holes may be left empty or, alternatively, may be sealed with plastic plugs, filled with closed cell foam or mechanical springs. The compression holes provide space for the displaced volume of sleeve elastomeric material to flow into during opening and closing of the gate. The gate valve construction of the present invention results in no leakage to the outside when the valve is fully open and no leakage to the outside or past the gate internally when the valve is fully closed. A lockout device of the invention has alternative positions for preventing the valve from opening or closing. In an alternative embodiment of the gate valve, the inner axial sealing end of each sleeve is located radially inwardly as compared to the location of the stiffening ring. As a further alternative, a groove is located along the radially inner surface of the sleeve in an arc of approximately 120 degrees, with the arc extending from the four o'clock to the eight o'clock position.

IPC: H04B10/275
Filed: 1998-06-10
Abstract: An optical fiber network of WDM type comprises two fibers which carry light signals propagating in opposite direction and which are arranged in a ring configuration. In the ring, one standby link between two neighboring nodes is used if another link fails. An add and drop node, used in the network only for traffic between neighboring nodes, has band blocking filters connected in respective fibers between a drop coupler and an add coupler. A drop coupler takes out equal shares of the light power to be received through simple switches and bandpass filters in receivers. An add coupler adds new wavelength channels produced in transmitters in the node through multiplexers and simple switches. The switches are used for receiving and transmitting on the wavelength channels in correct directions depending on the location of the inactive link. Thus, the positions of two of the switches have to be changed when the inactive link is one of the two links directly connected to the node. Such a node has a minimun of in-line components, and particulary, a minimum of in-line filtering components.

Abstract: The system coats wood chips or fibres with organic adhesive and feeds them into the space between an inner die (4) and an outer shape (3) using a granular spreader (1). The particulate is compressed by a piston (6) in a repetitive process to produce the extrusion. The bottom end of the die has a tapering profile (5) to allow the compressed material to relax. The final part of the process has the relaxed profile supported between an inner perforated guide (7) and outer continuous belt drives (9). The final, relaxed process applies heat via super heated steam, to set the material. The continuous belt drives are dragged along by the friction contact with the extrusion. The extrusion passes through a final cooling stage to remove residual steam and to dry the extrusion.
