Abstract: A mid-frequency loudspeaker drive unit includes a substantially conical diaphragm having a forward periphery and a surround connected to and extending from the forward periphery of the diaphragm to form a substantially smooth transition from the diaphragm to the surround, the diaphragm and the surround presenting a substantially smoothly continuous outwardly facing surface. The drive unit can be part of a compound loudspeaker drive unit including a high-frequency drive unit coaxially disposed within the diaphragm and a chassis encompassing the mid-frequency drive unit with the surround being secured to the chassis to form the smooth transition from the diaphragm to the surround.

Abstract: Binding device wherein a support structure (2) houses a pack of sheets provided with through-holes (133) aligned along a rectilinear edge of the pack. The structure moreover carries a binding member comprising a flat sheet-like rectangular member (100) showing, along a side thereof (100a), a plurality of flexible tongues (107) arranged combwise and a closure member (110) extending along the side (100a). The binding device is provided with a bending wall (70) mobile with respect to the pack and adapted to realize the bending of tongues portions projecting from the pack on an end flat member forming a first face of the same pack. A pressing device (90) further realises bending of the closure member (110) to arrange the closure member (110) on bent tongues (107) and on the end flat member (130b) thereby forming a bound fascicle.
Abstract: Methods and apparatus are described for receiving digital television signals where the receiver is capable of demodulating and demultiplexing the digital television signals from multiple, independent transmission channels. The preferred embodiment of the present invention provides for a Dual Channel Digital TV Receiver which receives signals from two independent transmission channels. In order to address each of the digital television signals from the two independent transmission channels, the Dual Channel Digital TV Receiver of the preferred embodiment of the present invention includes two independent paths for channel demodulation and transport stream demultiplexing. Thus, within the Dual Channel Digital TV Receiver of the preferred embodiment of the present invention, a signal from each of the transmission channels are received, decoded and sent for further processing or viewing, as desired by the user.
Abstract: A ski boot, in particular a ski-mountaineering or telemark boot, having a shell made of plastic material; a shank hinged to the shell; and a control mechanism, located at the rear portion of the boot, for controlling the tilt of the shank and having a lever hinged to a projection of the shank and movable between a work position in which one end cooperates with a rear projection of the shell to prevent rearward rotation of the shank, and a release position. The control mechanism has a ring hinged to the lever and engaging a recess formed in the rear projection of the shell to also prevent forward rotation of the shank with respect to the shell.
Abstract: A valve assembly having a cap defining a first and second fluid flow passage for allowing the flow of fluid is attached to a seat member which is coupled to an actuator. A plunger having an adjustably attached diaphragm is maintained within the seat member and the actuator, and the plunger positions the diaphragm over the first and second fluid flow passage. The actuator controls the plunger and determines the retraction of the plunger to allow fluid flow and the insertion of the plunger to prevent fluid flow.
Abstract: A ski boot, in particular a telemark boot, having a shell made of plastic material and in turn having a bottom wall, two lateral walls, a toe portion, and a flexible portion extending crosswise with respect to the shell, from one side to the other of the bottom wall at the metatarsus; and a frame embedded in the shell and having, integrally, two longitudinal elements extending along respective lateral walls from a rear portion of the shell to an intermediate portion of the bottom wall adjacent to respective lateral ends of the flexible portion, and a transverse structure connected integrally to respective front ends of the longitudinal elements and defined by a flat bottom portion embedded in the bottom wall, and by a top portion extending along the connecting portion between the toe portion and the flexible portion.
Abstract: A system for recording television programs for subsequent viewing by a user includes a preference determination module which is responsive to attribute information associated with television programs viewed by the user. The preference determination module categorizes the attribute information in accordance with categorization parameters to generate recordation preference information, indicative of television program viewing preferences of the user. The system also includes a recordation module which is responsive to the recordation preference information, for causing recordation on a storage medium of subsequently transmitted television programs, having attribute information corresponding to the recordation preference information.
