Abstract: ABSTRACT OF THE DISCLOSURE           A reversible turbine pump for producing bi-directional liquid flow wherein there is provided a housing having a substantially annular outer wall and top and bottom walls closing the ends of the outer wall. Within the housing there is a rotatable impeller having an annular series of blades extending outwardly and forming with the wall a toroidal space. First and second spaced outlet openings are provided in the housing and also first and second circumferentially spaced channels between the impeller and each of the outlet openings in liquid flow communication with the toroidal space. A dam is located between the channels. An inlet opening is located in each of the channels. Each of the inlet openings has a flapper check valve arranged to open and permit liquid to flow through the inlet opening in one direction of rotation of the impeller and close to prevent the flow of liquid through the opening in the opposite direction of rotation of the impeller, one of the flapper check valves being open when the other is closed during impeller rotation. The inlet openings are dimensioned such that flow of liquid through the opening is in a volume greater than the capacity of the impeller to move the liquid through the toridal space. There is also provided a liquid reservoir to supply liquid to the inlet openings in a volume at least equal to the inlet opening liquid flow through volume.

Abstract: ABSTRACT OF THE DISCLOSURE A method and system for the detection of plate clashing in disc refiners are provided herein.  The signal from either an acoustic or vibration monitor is processed through a filter which isolates those distinct predeter-mined frequencies at which a significant increase  in signal level is known to occur during a clash or are generated in association with imminent or ac-tual plate clashing, the distinct frequencies being related to the clash and to the characteristics of the discs of the refiner.  The signal level of the filtered data is compared with a threshold level at which protective action must be taken.  Protection  can be automatically initiated by the plate clash detection system, e.g., by automatically opening an electrical operation cir-cuit to at least one of a plate closing means, refining pressure retaining means and a motor turning the refiner plates.  Alternatively, it can be done manually by an operator, using the detection system as a warning device.

Abstract: ABSTRACT OF THE DISCLOSURE       A controlled release wall structure is provided which relies on controlled strength distribution and which dis-engages from a building framework at a selected applied load -- failure load -- and collapses in the direction of the applied load, that is, inwardly or outwardly of the building.  Under normal wind load conditions, the present wall structure will safely sustain the expected elastic deflection and working stresses.  However, under abnormally high loadings such as applied by explosion forces or by tornado and hurricane wind forces, the present wall structure collapses to create a substantial open area whereby a minimal loading is transmitted to the structural framework.  The present wall structure protects the building framework from being overstressed during tornadoes or hurricanes; and also is capable of quickly relieving excessive pressures generated by an explosion within or without the building.  The present wall structure includes at least one composite panel which spans the distance between at least first and second frame members, and which has one panel end releasably retained on the first frame member.  According to this invention the composite panel is provided with a discontinuity in the region between the first and second frame members, which reduces the bending strength of the composite panel.  The discontinuity extends parallel with and is spaced at a "selected distance" from a proximate edge of the first frame member.  The "selected distance" determines the failure load of the wall structure.

Abstract: Case No. ZE1781 INSULATING-SLABS AND THEIR USE             Abstract of the Disclosure Freshly-formed hard-foam plastic slabs which are preferably susceptible to maximum shrinkage are used as a base for insulating masonry structures.  Each slab is grooved and has raised portions (lands) between adjacent grooves.  Fastening elements (pins) are dispersed over the grooved surface to secure a reinforcing web to the slab and maintain it at a substantially uniform distance therefrom. To insulate a masonry structure, such as a wall, the face of the wall is covered with such slabs, which are secured to the wall.  The exposed surface of the slabs is then plastered with a material which permits the passage of water vapor therethrough.  The applied coating of plaster fills the grooves on the slab surface and is thick enough to cover the reinforcing web.  A suitable finish coat of plaster or paint is optionally placed over the initial reinforced plaster coating.

Title: Deeply filtered television image display
Inventor: LIBMAN PHILOMENA C
IPC: H01J29/32
Filed: 1979-10-30
Granted: 1982-06-08
Abstract: ABSTRACT OF THE DISCLOSURE           A low-cost, deeply filtered television image display is depicted.  A viewing screen includes a patterned layer of phosphor particles disposed contiguous to the inner surface of the display.  The layer when excited emits light of a predetermined color.  The display includes means for exciting selected areas of the layer to produce a luminescent informational image.  The image is subject to loss of contrast caused by reflection of ambient light from the layer.  The improvement comprises a shallow, random, clumped, discontinuous, open dispersion of contrast-enhancing particles of pigment having a body color corresponding generally to the predetermined color disposed directly on the viewing screen beneath the layer and not significantly admixed with the phosphor particles.  The percentage of open area of the dispersion of pigment particles and the absorption characteristics thereof are such that the dispersion efficiently filters ambient light at its interface with the layer.  This filtering is accomplished first by absorption of directly incident ambient light, and secondly by absorption of ambient light passing through the open dispersion and scattering back off the phosphor particles to the dispersion.  The dispersion represents a tolerable impediment to image light emitted by the phosphor particles due to the shallowness and openness of the dispersion and its non-absorption of light of said predetermined color.  The dispersion negligibly absorbs electron beam energy due to its location beneath the layer.  As a result, deep filtration of ambient light and thus high picture contrast is made practicable without a disproportionately countervailing loss in picture brightness.

Abstract: A METHOD AND MEANS FOR ELECTROCHROMIC TEXTURE DISPLAY                 Abstract A method and means for creating the display illu-sion of "roughness" or "texture" in color patterns suitable for a raster scanned display surface by assigning different color values to pels (picture elements) in adjacent positions and then replicating the patterns automatically using the recurrent and sequential accessing of a concordance table.  The real colour of each pel of a textured pattern is a joint function of a color number stored in a refresh buffer driving the display surface for any given display matrix array pel position and the value of a predeter-mined subset of address bits which describe that pel position.  The use of preselected pel position address bits for regulating texture is shown as applied to video lookup tables and refresh buffers as a single level control and additionally to two or more video lookup tables for achieving a pattern hierarchy.
