Abstract: 1. Needle contact element for a safety contact rail. 2.1 Known safety contact rails are produced, for example, from a hollow rubber profile and a rib resembling a knife edge, arranged in the hollow rubber profile, both having electrically conductive zones. In known versions, these zones are connected via rivets, clips or screws to switching lines which transmit electrical switching pulses during the deformation of the hollow rubber profile and the connection of the hollow rubber profile and rib caused thereby. The known connection devices of switching lines and electrically conductive zones have not proved sufficiently reliable. 2.2 According to the invention, this disadvantage is avoided in that there can be inserted into the electrically conductive zones of the rib 2 and of the hollow rubber profile 1 needle contact elements 10, 11, to which the switching lines 8, 9 can be fastened, for example via a screw-type clamping device. At the same time, the needle contact elements have increasing conicity towards their free end and a needle tip 18 which forms an angle of approximately 70 DEG . <IMAGE>

Abstract: An acoustic displacement flowmeter uses a high-compliance acoustic-type displacement transducer to measure fluid flow accumulated by temporarily restricting the flow of a fluid along a path. The displacement transducer signal, representative of fluid flow rate, is integrated after an initial settling period elapses, and the integrated signal is periodically sampled. The number of samples taken during a measurement cycle depends upon the slope of the integrated signal and the maximum sample period permitted. The samples are summed and the actual flow rate is computed by a microcomputer.

Abstract: A general massively parallel computer architecture supporting neural networks is developed utilizing a novel method of separating a triangular array containing N processing elements on each edge into multiple smaller triangular arrays, each of dimension X and each representing a common building block processor group chip, that can be interconnected for various size parallel processing implementations. The group chips are interconnected by a unique switching tree mechanism that maintains the complete connectivity capability and functionality possessed by the original triangular array of dimension N. A partitioning approach is presented first, where for a given size K and X, and K is divisible by X, it is proven that a triangular array containing K processor elements located on each edge of an equilateral triangular array can be partitioned into K/X triangular arrays of dimension X and  K(K-X) / 2X ² square processor arrays of dimension X. An algorithm is presented next which partitions a square array into two triangular arrays, each of dimension X. Assuming K=N and the chosen technology supports the placement of a triangular processor group chip of dimension X on a single chip, the final scalable massively parallel computing structure for N root tree processors utilizes  N ²/ X ² triangular processor group chips. Examples of using the partitioning methodology to create the scalable organization of processor elements are presented. Following these examples, an interconnection mechanism is developed which is shown to preserve the functionality of the original triangular array of dimension N in the implemented structure constructed of multiple triangular arrays of dimension X. Examples of the interconnection mechanism for two scaled neural network emulation massively parallel computers utilizing the same size X processor group chip are presented. Finally, an alternative scaling mechanism and implementation considerations for the interconnection mechanisms are discussed.

Abstract: An ink-cooled inkjet print cartridge (20) has an efficient heat exchanger (22) located on the back side of the substrate (30) that eliminates the need for heat sinks. All ink (38) flowing to the firing chambers (40) goes through the heat exchanger (22). The geometry of the heat exchanger (22) is chosen so that almost all the residual heat absorbed by the printhead substrate (30) is transferred to the ink (38) as it flows to the firing chambers (40). Additionally, the pressure drop of the ink flowing through the heat exchanger (22) is low enough so that it does not significantly reduce the refill rate of the firing chambers (40). The heat exchanger (22) can have one or more active heat exchanger sides. The heat exchanger has little thermal mass itself and significantly reduces the thermal mass of printhead by eliminating the need for a heat sink. This reduces the warm-up time of the printhead to a fraction of a second.

Abstract: The invention relates to a method for preparing a hydraulically settable cement base material starting from steel slags formed in a steel-making process, which method comprises the formation, in steel slags in the liquid state, of a ferrite gradient by adding a ferrite-precipitating compound, the separation, if required, of the high-ferrite fraction formed, the separation of at least the low-ferrite fraction formed, the cooling and the comminution thereof to obtain a hydraulically settable material. The ferrite-precipitating compound used has preferably acid components, and can expediently generate silicic acid. At least before the cooling of the low-ferrite fraction, the aluminium content of the liquid slag material is regulated by the addition of an aluminate-containing material, such as bauxite. The high-ferrite fraction separated can be returned to the steel-making process to reduce or remove the addition of a flux in the production of steel.
