Patent EP-0245015-A2 (EP)
Inventor: ARBOGAST THOMAS P
IPC: B60R22/41
Filed: 1987-04-29
Abstract: There is provided an improvement in a seat belt retractor mechanism of the type having a seat belt reel rotatably mounted in a support frame adapted to be asembled on a movable door of a vehicle, wherein the reel has at least on one end a generally circular ratchet plate for engaging a locking element movably mounted on the support frame between a first position allowing the reel to payout the belt freely and a second position engaging the ratchet plate to hold the reel against rotation to payout the seat belt. An inertia sensing element carried by the support frame shifts this locking element into the locked position upon being moved by inertia forces caused by rapid acceleration or deceleration of the vehicle to which the mechanism is mounted. In addition, an electromagnet is employed for increasing the amount of inertia force needed to move the inertia sensor element during such rapid changes in speed of the vehicle. This electromagnet is energized when the door is opened so that movement of the door itself by the occupant in entering or leaving the vehicle will not trip the sensor element. The improvement is the provision of a generally flat pole surface for the electromagnet and a generally flat keeper surface which are engaged in a generally coplanar relationship to cause the increased inertia force by magnetic attraction between the engaged surfaces upon energizing the electromagnet when the door is open. When the door is closed, there is no magnetic force between the engaging surfaces so that the inertia sensor element is moved by normal inertia forces.

Abstract: The present invention provides a method for pro­ducing a self-supporting ceramic composite by the oxida­tion of a parent metal (10) to form a polycrystalline cera­mic material consisting essentially of the oxidation re­action product of the parent metal (10) with an oxidant, including a vapor-phase oxidant, and, optionally, one or more metallic constituents. A permeable filler material, such as a preform (14), with at least one surface bearing a permeble stratum (18), is contacted with a body of molten parent metal (10) heated to a temperature above its melting point but below the melting point of the oxidation reaction product. At least a portion of the oxidation re­action product is maintained in contact with and between the molten metal (10) and oxidant to transport the molten metal through the oxidation reaction product toward the permeable stratum (18) and into contact with the oxidant so that the oxidation reaction product continues to form at the interface between the oxidant and previously formed oxidation reaction product that has infiltrated the filler material. The reaction is continued to infiltrate at least a portion of the stratum (18) with the oxidation reaction product and to produce an intermediate ceramic body having an adjacent ceramic composite overlaid with a ceramic stra­tum. The ceramic stratum is removed from the underlying ceramic composite to produce a self-supporting ceramic com­posite having the surface established by the permeable stratum (18).

Abstract: The invention relates to a ski brake with two brake arms arranged on both sides of the ski, which are respectively formed with an adjoining pivot-shaft part and a holding arm made of an essentially Z-shaped round wire piece. In this connection, the pivot-shaft parts are aligned approximately at right angles to the longitudinal axis of the ski and approximately coaxially with one another and mounted on the upper side of the ski by means of a holding plate. Furthermore, the free ends of the holding arms are angled towards one another and serve as a bearing for a pedal which can be operated by the ski boot and which forms an arm of a toggle lever, the second arm of which is mounted firmly on the ski at a distance from the pivot-shaft parts and the toggle joint of which is formed by a pivot and slide bearing, the brake arms being pivotable, against elastic force, out of the braking position into a position parallel to the ski and, in relation to the ends of the holding arms, pivotable in towards the longitudinal axis of the ski into a position of readiness, and the pivoting-in taking place by means of a relative movement of the pedal in relation to the holding arms. To achieve the aim of developing and designing such a ski brake in such a manner that, while maintaining its specific advantages, a simplification of the pedal can be achieved, which on the one hand permits more economical manufacture and on the other hand increases the operational safety of the ski brake, the pedal (9, 29) has at least one operating element (15, 34) which is provided to interact with the angled sections (8, 28) of the holding arms (6, 26).

Abstract: A controlled impedance connector assembly comprised of a mutually engageable plug and receptacle for termination of coaxial cable leads in a manner which enables rapid attachment to and detachment from a user board of a very large number of signal leads while ensuring an acceptable level of controlled impedance from the coaxial cable to the user board. The receptacle includes a backup plate and a plurality of metallized grounding segments fixed to the backup plate and having a plurality of spaced parallel terminal receiving bores therein extending between opposed surfaces. An insulation plate is fixed to each grounding segment and overlies one of the surfaces. A plurality of pin contacts are fixed to the insulation plate such that a head member extends into an associated terminal receiving bore and an oppositely directed tail member is adapted for termination at available circuitry. The plug includes a frame mounting a plurality of dielectric segments each having a plurality of parallel spaced terminal receiving bores extending between a front and rear face. The dielectric segments are floatingly mounted for movement within defined limits in directions transverse to the axes of the terminal receiving bores. A terminal mounted to the extremity of each of a plurality of coaxial leads is removably received in an associated terminal receiving bore with a locking spring being utilized to prevent inadvertent removal of a terminal but subject to purposeful manipulation to enable removal of the terminal.   
     Each bore of the grounding block receives and retains a barrel spring for frictionally holding a terminal in place engaged with the lead member of a pin contact. In another embodiment, a plurality of side by side dielectric strips replace the single insulative plate and permit soldered connections between the pin contacts and stripline cable at a location remote from the receptacle. When the heat employed in soldering the connections has dissipated, the strips are then attached to a one piece grounding block thereby avoiding harm of other components by reason of the heat. The dielectric strips are shaped to enable termination of a high density of stripline cables without causing undue interference between neighboring cables.
