Inventor: HALDER PRASANTA DIPL-ING
IPC: F28F9/02
Filed: 1991-10-10
Abstract: A heat exchanger having a tube plate made from plastic and a multiplicity of tubes extending in parallel whose ends are sealingly accommodated in the tube plate, has a plastic water box which is fastened in a liquid-tight fashion to the tube plate by means of friction welding. For this purpose, both the tube plate and the water box have a flat surface which serves the purpose of joining by friction welding. In order for the water box to be fastened reliably - but detachably in case of need - before the friction weld joint is produced, the water box or tube plate is provided with means for gripping an edge from behind in a form-fitting fashion, these means and the edge being operationally connected only until the friction weld joint is produced. <IMAGE>

Abstract: A microwave mixer (10) is formed of three orthogonally oriented waveguides (12, 14, 16), each having a rectangular cross-section defined by a pair of opposed broad walls (46) and a pair of opposed sidewalls (48) wherein the ratio of cross-sectional dimensions typically is 2:1. The mixer includes an input coupling probe (22), a mixing region (30), and an output filter (24) disposed serially along a first of the waveguides. A second of the waveguides applies a reference LO signal via the probe to the mixing region, the mixing region employed in the preferred embodiment of the invention. A section of dielectric board (32) serves to support the diodes of the mixing region, components of the filter (24), and the probe in the first waveguide. The third waveguide applies an RF input signal to the mixing region via an input port (16) in a side of the first waveguide, and via an impedance matching taper (58) and a waveguide section of reduced height (62) which impedes egress of both an IF and an image signal produced in the mixing region by interaction of the LO and the RF signals. The filter (24) is located at the mixer IF output port (34) for reflecting an image-frequency signal back to the diodes of the mixing region for further interaction with the LO signal to generate additional IF signal in phase with the originally produced IF signal for additional power and a significantly higher signal-to-noise ratio.

Abstract: A technique for displaying the results of a query on a database. The technique associates a subquery of the query with a space in a display and represents the results of the subquery by means of a symbol whose appearance varies with a characteristic of the results of the subquery. In a preferred embodiment, the technique is used with queries on a data base of statistical articles. The display is a grid with each field of the grid representing a journal-year pair. A symbol appears in the field if a search of the data base results in a minimum number of hits in the year and journal represented by the pair. The appearance of the symbol varies with properties such as the number of hits and the number of pages in the hits. Bar graphs along the sides of the grid indicate total numbers of hits per journal and year. The symbol for a given journal-year pair changes its color when the pointer is moved over it, and if a mouse button is depressed when the pointer is over the symbol, the data base references for the hits corresponding to the journal-year pair are displayed in an article view window. Sliders control the number of hits required for the display of a symbol and the size of the symbols. The implementation employs memory mapping and caching techniques to achieve rapid generation of a display from the results of a search.
