Title: Beam generating system for electron beam measuring instruments
Inventor: LISCHKE BURKHARD
IPC: H01J37/07
Filed: 1988-09-26
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE        Beam generating system for electron beam measuring instruments.  In prior art beam generators, the life expectancy of directly heated boride cathodes is limited by their thermally disadvantageous mount.  The present invention provides a cathode not clamped at the lower end of the crystal shank as was previously standard, but clamped immediately below the cathode tip.  The inventive mount of the boride cathode results in the crystal being only insignificantly hotter in the region of the clamping plane than at the electron-emitting tip.

Title: Heat exchange device
Inventor: LEE YONG N
IPC: F28F13/12
Filed: 1988-11-04
Granted: 1990-11-06
Abstract: ABSTRACT     A heat exchange device including at least one inner cylinder member and at least one outer cylinder member, defining therebetween one or more annuli through which pressurized heat exchange medium is forced to flow.  One or more rotatable members having formed thereon a plur-ality of finger-like projections that define longitudinal continuous or segmented grooves are disposed within the annuli,  The pressurized heat exchange medium imparts angular force to the rotatable member causing it to flow very rapidly with great vorticity within the grooves and also between the distal ends of the finger members and the adjacent containing circumferential surface of the inner and outer cylinder members. In some cases, angular force is imparted to the rotatable member(s) by external power sources, as a supplement to the flow of the pressurized heat exchange medium. The rapid flow and vorticity of the heat exchange medium is effective to achieve at least a ten fold increase in heat transfer gradients or coefficients while at the same time maintaining only a nominal increase in pressure drop through the device.

Abstract: The invention relates to a method for the manufacturing of a wind barrier or breather web (7), especially in connection with the manufacturing and mounting of construction elements, as well as a method for the manufacturing of a special web in which such a wind barrier is included. The invention is to the fact that a filt web (7a) is joined with a plastics layer (7b) which in connection with its application to the filt (7a) provides zones allowing for the diffusion of moisture through an otherwise waterand windproof finished web product (7). Possibly, there may be used a crude plastics material which is mechanically foamed or comprises an additive which under the influence of heat creates vapour blisters or gas pockets which provide thin fields and together with the embossing function of the filt and/or the press rollers onto the plastics layer form the diffusion zones. The novel wind barrier or breather web has a small mass and thus provides a final product which is very little fire incentive. The wind barrier web is also applicable for further treatment in the form of a special web, a so-called integrated ground beam membrane which replaces the use of separate mineral wool strip,impregnated foundation wall felt and breather paper in connection with a beam arrangement on concrete foundation.
