A contact body is disclosed, comprising at least two contact sheets having opposing surfaces and a projection extending outward from one surface of each contact sheet, wherein the projection defines a depression on the opposite surface of the contact sheet, a projection of one contact sheet being disposed within a depression of an adjacent contact sheet to form a projection-depression coupling, and the projection-depression coupling being deformed to form a positive lock. A method and apparatus of connecting contact sheets to form a contact body are also disclosed, that provide for deforming projection-depression couplings formed in two or more interlocking sheets to form positive locks by which assemblies of sheets are formed. The apparatus includes crimping devices that crimp projection-depression couplings located in the interior area of the interlocked sheets and projection-depression couplings located adjacent the side edges of the interlocked sheets, again to form positive locks by which assemblies of sheets are formed.

Families of periodic space structures, configurations, labyrinths and space frames based on seven different known periodic space grids composed of one edge-length and even-sided polygons. The space structures have two different polyhedra corresponding to the vertices of the source grids. The space labyrinths are characterized by a continuous surface having two types of vertices and dividing space into two parts. The space frames have one type and length of strut and two different shapes of nodes. The structures have cross-disciplinary applications in the design and scientific fields. In architecture and design fields, applications for building systems one earth or outer space, architectural space layouts, environmental sculptures, playground structures, honeycomb structures, toys, puzzles, model-kits, etc. are possibilities. The space labyrinths, besides their architectural applications, provide model geometries for the design of synthetic molecular filters, micro-filters for purification of liquids and gases, and designs for micro-screens.

A completely electronic taximeter has a first storage which has sufficient capacity for storing all variables required for calculating an individual fare and for storing totals required for determining the payment of the taxi driver. During operation of the taximeter the variables referring to the individual fare are transferred from the first storage to a buffer storage. Synchronizing means transfer the contents of the buffer storage in sequence to corresponding indicator elements. Although each indicator element is energized only briefly the repetition rate is sufficiently high to cause a constant visual indication. The capacity of the buffer storage is only large enough to store the values required for such indicator.

A splash bar for direct heat and mass transfer method and apparatus are disclosed utilizing grids of elongate splash bars which bars are arranged generally vertically and parallel with one another and wherein each splash bar includes both flat and curvilinear surfaces all of which are substantially perforated with holes. In one embodiment, the splash bar has a short first curvilinear surface that extends laterally and which changes to an extended first straight surface that in turn changes to a short second curvilinear surface which extends toward the vertical downward direction. In a second embodiment, the first straight portion is shorter and the second curvilinear surface changes to a third curvilinear surface with a reverse incline which changes to a second short straight surface which in turn changes to a fourth curvilinear surface that extends towards the vertical downward direction.

According to the invention the layers are formed by a plurality of packing parts (1), the packing elements (10) comprise support structures (4) into which the packing parts are inserted, and the packing parts are substantially cylindrical.
摘要:
A method and apparatus for concurrently catalytically reacting fluid streams and distilling the reaction product. A catalytic structure is provided within a distillation column reactor and includes mass transfer devices presenting hollow spaces and a fixed catalyst bed formed from solid catalyst particles. The mass transfer devices are interconnected gas and liquid permeable elements. The liquid phase preferentially flows along channels formed in the catalyst bed before contacting the devices for mass transfer with the vapor phase which primarily flows through the devices.
