Abstract: The data source (for long-wave single-sideband transmission of the RDS signal (SSB-RDS))is an RDS coder capable of QDSB modulation with or without the carrier frequency. The RDS-SSB signal with vestigial carrier is produced by the filter method and converted to the transmission frequency by mixing. The road traffic information carrier which can be fed into the RDS coder can thus be used as the vestigial carrier. A known all-band receiver with synchronous demodulator is used for receiving the SSB-RDS signal. Further processing of the RDS baseband (biphase signal) is a straightforward matter.

Abstract: The invention concerns an end-strip which prevents the fraying of pieces of carpet comprising a pile layer and backing, in particular a plinth strip for finishing the edges of an area covered with fitted carpet, the end-strip having a U-shaped cross-section and the distance between the two legs corresponding approximately to the thickness of the piece of carpet. The invention further concerns a plinth strip for finishing the edge of an area covered with fitted carpet, with a strip-shaped piece of carpet comprising a pile layer and backing and with a strip which is approximately U-shaped in cross-section. The plinth strip is pushed onto the longitudinal edge of the strip-shaped piece of carpet remote from the fitted carpet, such that the strip legs engage about the pile layer of the piece of carpet and its backing.

Abstract: A device for detecting deformations in solids includes a casing constructed and arranged to be insertable in a solid. The casing has walls defining a substantially closed container. The container has an inner dividing wall separating the container into an upper enclosed section and a lower enclosed section. A fluid substantially fills the lower enclosed section and is in fluid communication with the interior walls of the lower enclosed section. A first strain-sensing system is in fluid communication with the lower enclosed section of the container such that deformation of the walls causing pressure changes in the fluid are detected by the first strain-sensing system. A second strain-sensing system is disposed in the upper enclosed section. The upper enclosed section is at least partially filled with fluid. A valve fluidly couples the second strain-sensing system to the lower enclosed section. The valve is operatively associated with the first strain-sensing system and is normally closed, preventing fluid in the lower section from communicating with the second strain-sensing system. The valve is constructed and arranged to open in response to a signal sent from the first strain-sensing system when the first strain-sensing system reaches an operating limit of strain measurement, thereby protecting the first strain-sensing system from being damaged from strains exceeding the operating limit thereof. The second strain-sensing system is constructed and arranged to measure the excessive strains.

Abstract: A shaft (44,144,145) is conventionally driveably connected to a bore (46,146) by a steel key of rectangular cross-section. Where the shaft is of smaller diameter than the bore, a slotted nylon sleeve is fitted between them and a tall steel key extends through the slot. Failure of both standard and tall keys can occur for various reasons. A unitary component (50,162,163) of suitable plastics material or non-ferrous metal is therefore proposed. This component essentially includes an integral key (56,174) of curved cross-section adapted to engage in a mating keyway (176) formed in the bore. Where the shaft (44) and bore (46) are nominally of the same diameter, the component (50) consists also of an integral key (52) of rectangular cross-section adapted to engage in the conventional keyway (48) in the shaft. Where the shaft (144,145) is of smaller diameter than the bore (146), the component (162,163) also includes a sleeve (164) with the key (174) of curved cross-section formed on its outer periphery, and a keyway (170) of rectangular cross-section formed in its inner periphery and adapted to be driveably connected by a separate standard key (171) to the conventional keyway (148,149) in the shaft. The component is useful in the flange-mounting of different electric motors on off-the-shelf gear units. <IMAGE>
