Abstract:
This invention is an implementation of a congestion control mechanism, especially for ATM networks supporting data services or other nonreserved bandwidth traffic, e.g. in multimedia applications. It reacts immediately upon detection of a traffic bottleneck by selectively and temporarily holding back the data traffic that is to pass the bottleneck (5). A congested node (3) transmits congestion notifications (36) containing routing label information and deferment information to upstream nodes (2), thus enabling selective, temporary throttling action. If congestions persist, further notifications may be spread backwards step by step, eventually reaching the sources. A specific implementation is given for PRIZMA type switching nodes.
Abstract:
Reinforcing fiber materials such as rovings, webbings, and other fiber maials are impregnated with a resinous binder material in such a manner that gaseous inclusions are avoided whereby a surprising increase in the strength of the fiber compound material is achieved. For this purpose the liquid resinous binder material is applied substantially only to one side of the reinforcing material which is then moved through an absorbing zone in which the liquid resinous binder material penetrates the reinforcing material substantially completely as a result of a predetermined residence time and temperature in the absorbing zone. Gas inclusions are removed by adsorption and/or by expulsion. The gas adsorbing and expulsion zone is a chamber in which a plurality of guide rollers are arranged so as to cause the impregnated material to repeatedly reverse its moving direction, whereby the sequential and repeated penetration of the reinforcing material by the resinous material and the removal of gas inclusions are enhanced. Further, the precise weight ratio adjustment of resin to fiber material is enhanced by moving the impregnated material in a substantially vertical orientation through a fulling station. The vertical orientation facilitates the flow off of excess resin.
Abstract:
A connecting rod assembly includes an axially elongated member with openi spaced apart in the axial direction. The axis of the openings extend perpendicularly to the axis of the member. A connecting rod shaft extends in the axial direction of the member between the two openings. A fiber reinforced plastics material belt extends around the first and second openings and also around the connecting rod shaft. Oblique cuts are formed in the belt on opposite sides of the connecting rod shaft adjacent one of the openings. A highly heat-resistant adhesive is placed in the oblique cuts for splicing the belt together.
Abstract:
Shear transfer elements can be formed by winding or weaving unidirectional fibers on a support structure. In a winding operation the support structure consists of two intersecting planes of winding mandrels with the planes arranged in angularly spaced relation. Each plane has two pair of mandrels with the mandrels in each pair located on the opposite sides of the line of intersection between the two planes. After the fibers are wound on the mandrels, each mandrel is axially disposed in the opposite direction relative to the other mandrel in the pair and also to the adjacent mandrel in the other pair in the same plane. Next, the fibers are pressed to form the shear transfer element. In a weaving operation, the support structure consists of a pair of pivotally interconnected frames. The fibers are woven onto holders on the sides of each frame extending parallel to the pivot axis of the frames. After placement of the fibers on the frames, the frames are pivoted apart and the fibers are pressed to form the shear transfer element.
