The conduits of each pair are disposed convergent with respect to each other in order to generate a triangle of interaction of the air jets at the output ring.

Abstract: A connector arrangement comprises a rigid inner conductor (107), a dielectric sleeve (111) arranged around the inner conductor and a rigid outer conductor (109) arranged around the sleeve. A surface of at least one of the inner conductor, the sleeve and the outer conductor is provided with a taper, such that the sleeve fixes the relative transverse positions of the inner and outer conductors at a first end of the arrangement and not at a second end of the arrangement. The inner conductor is longitudinally slidable relative to the outer conductor. Such an arrangement is suitable for use in hostile environments, such as in high temperature pipelines, in which there are large temperature variations and in which the positional variation of mating connectors is high.

Abstract: The invention relates to an aircraft engine having a longitudinal axis (XX?), comprising a wall (30) surrounding a gas stream that is ejected at a downstream end (30a) of the wall along the longitudinal axis, characterized in that a plurality of conduits (60, 62, 64, 66, 68, 70, 72, 74) distributed at the periphery of the downstream end of the wall are each capable of ejecting, via an outlet orifice (60c), a fluid jet (76) in the form of a sheet, in such a way that the jets thus ejected each form a fluid perturbation around the ejected gas stream.

Abstract: A real-time detection technique and a real-time, adaptive, model-independent control technique for detecting and stabilizing pathological physiological rhythms, such as repolarization alternans, on the basis of the rate dependence of excitable tissue such as cardiac and neuronal tissue is presented. Unlike other control methods, which require a number of beats to locate the period-1 fixed point, the technique locates the period-1 fixed point almost instantaneously, rapidly eliminating any higher-period or aperiodic rhythms.

Abstract: The invention relates to a type plate for machines which serves as a support for written and/or graphical information. The inventive type plate is provided with a storage device which is integrated therein and which is suited for inputting and outputting data.

Abstract: A connection arrangement includes a first connector (12) with an opening leading to first and second contacts (14, 16), where the first contact includes a beam (40) that is biased upwardly against the second contact but which can be depressed out of engagement with the second contact. The beam is depressed by a plug inner contact (32) of a mating second connector (30) that passes into the opening and depresses the beam, in an arrangement that assures firm engagement of the plug inner contact with the beam despite small beam movement. A stop (70) lying under the beam, limits its downward movement by the plug inner contact. The plug inner contact is spring biased downwardly with respect to the second connector frame (36) but can move up, so the second connector can continue to move down a short distance after the plug inner contact has pushed the beam against the stop, to enable-full engagement of largely coaxial outer contacts (26, 34) of the first and second connectors.

Abstract: A switch assembly is provided for mounting on a circuit board and for receiving a coax connector plug that opens the switch and connects the central coax plug element to one of the switch contacts, which enables the use of a plug (100) without a long projecting center contact element (102) and which enables many degrees of misalignment between the plug and switch. The switch (10) includes a housing (11) with an exposed upper face (22) having an entrance (24) for receiving the connector plug. First and second contacts (12, 14) are mounted on the housing, with the first contact including a resilient beam (18) biased up against the second contact but deflectable downwardly out of engagement with the second contact. An electrically conductive projection (19) projects upward at least partially through an opening (26) at the bottom entrance, so the center contact element of the plug does not have to project deeply through the opening in order to operate the switch and electrically connect to the beam.

Abstract: An innovative but easy to use on-line guide is provided to provide the user of a multiple channel television broadcast system a wealth of programming information in a simple format that is easy to understand. The guide enables the user to easily select a particular program to watch. In particular, when the guide is presented to the user, the guide covers only a portion of the actual television screen or display. The remaining portion of the television screen continues to broadcast the audio and video of the currently selected program. As a user scans through the guide and moves the pointer from one station to another, the system responds by automatically tuning to the channel pointed to by the pointer and provides the audio and displays the video in the portion of the screen not covered by the guide. Thus, the user can easily get an idea of the broadcast on a particular station without exiting the guide and without expressly selecting a particular channel.
