Abstract: An automatic device prepares blood films or smears on microscope slides. The device has essentially one moving part, namely a carriage which holds the slide, and which is movable back and forth along a frame. The slide is dispensed from a magazine, onto the carriage, and the carriage moves to a position where a drop of blood is conveniently placed onto the slide. The carriage then moves to a position permitting contact between the blood and a spreading blade mounted on a flexible member. The carriage is moved in a forward direction, causing the blade to move relative to the slide, creating the blood smear. The slide is then lifted from the carriage and moved onto a storage platform. Meanwhile, the blade is cleaned as it passes over a cleaning pad on the carriage. Movement of the carriage in both directions insures that both sides and the end of the blade are cleaned.

Abstract: A system is provided for producing a three dimensional object from a reactive liquid medium capable of being solidified. The object is constructed from many successive layers of the solidified reactive liquid medium when subjected to appropriate synergistic stimulation. A reservoir contains both the reactive liquid medium and an underlying supporting, substantially immiscible, non-reactive liquid medium.

The synergistic source radiates toward the reactive liquid medium and imaging apparatus defining a three dimensional object of required configuration selectively controls the size and shape of that part of a new two dimensional layer to be solidified. At least part of the new layer is solidified, after which a further layer is applied.

The control circuit is electrically connected to the adjusting mechanism for varying the angle of the doctor so that the physical dimensions of the microfolds are optimized.

Abstract: A spray method and apparatus for uniformly coating a surface with a high degree of efficiency includes filling the pores of a porous sheet with a liquid and then directing compressed fluid from a nozzle into the sheet from one side to spray the liquid onto a surface spaced from an opposite side. Because the total volume of the pores is known, the volume of the sprayed liquid is also known. Moving the nozzle relative to the sheet and the substrate enables the entire surface to be uniformly coated. The size and distribution of the pores on the sheet define the distribution of the liquid sprayed onto the substrate. The coating may be a thick or a thin film of uniform thickness, or may even comprise a recognizable pattern.

The deposited ultra-fine particles are collected from the part of the moving particle carrier while evaporated ultra-fine particles deposit onto another part of the moving particle carrier.

Abstract: A blood analyzer system transports blood samples through at least one blood analyzer and an automatic blood smear generator under the control of a preprogrammable controller. Blood samples are stored in containers that identify the blood samples they contain. The containers move through the system mounted in protective racks that permit the reading of the identifications. The results of analysis by one or more blood analyzers in the system determines for each sample individually whether or not to make a blood smear. When a blood smear is to be made, the controller makes the smear thickness of each blood sample consistent with other samples whatever the consistency of the sample to be smeared. If a required sample is not made, a detector sounds an alarm, thereby alerting operators that the system has failed.

Abstract: A deflection-compensated doctor blade beam of a coater used for coating web materials. The doctor blade beam comprises a box-section frame (3), together with a holder (2) of the doctor blade (8), and a support tube (4) placed inside the frame (3). The support tube (4) is backed against the frame (3) preferably with three asymmetrically placed compensating elements (5), which advantageously are pressurized hoses. The deflection of the doctor blade beam is accomplished by varying the volume of the compensating elements (5) through pressure alterations in the elements. A displacement of desired direction can be achieved by differentially pressurizing the three compensating elements (5). By using this apparatus, the deflection of the doctor blade can be compensated to full straightness. The compensating system is controlled with the help of a feedback loop using data from a direct measurement of beam deflection, or alternatively, from the coat thickness profile.

Abstract: A relatively large-sized square substrate for use in the production of a color filter for liquid crystal display, a color image sensor or the like is applied with a coating film of a viscous liquid such as a photosensitive resin. For producing the coating film, the substrate is placed with its surface extending horizontally and the viscous liquid is dropped on the surface in a line along an edge portion of the surface. Then, a squeezee rod is moved along the surface with a predetermined gap maintained between the squeezee rod and the surface, to spread the viscous liquid over at least a part of the surface, whereby a predetermined thickness of the spread viscous liquid is obtained. Thereafter, the substrate is spinned in the plane of the surface thereof to disperse the spread viscous liquid uniformly by centrifugal force over the entire surface of the substrate, whereby a thin coating of the liquid of a uniform thickness is formed on the surface of the substrate.

Abstract: A method and process for computer-controlled manufacture of three-dimensional objects involves dispensing a layer of liquid, insoluble material onto a platform at predetermined locations, which then hardens. A second media, preferably water soluble, is then sprayed onto this layer to thereby encapsulate the hardened insoluble media. The uppermost surface of this encapsulant is planed, thus removing a portion of the encapsulant to expose the underlying insoluble material for new pattern deposition. After the resulting planing residue is removed, another layer of liquid, insoluble media is dispensed onto the planed surface. The insoluble media can be of any color and may vary from layer to layer, and from location within a layer to location within a layer. These steps are repeated, until the desired three-dimensional object, surrounded by a mold, is completed. At this point, the object is either heated or immersed in a solvent, thereby dissolving the mold and leaving the three-dimensional object intact.

Abstract: An oil-spreading squeegee for roadway maintenance uniformly spreads oil sprayed onto a roadway surface to be maintained or upgraded. The squeegee assures a surprisingly uniform surface, particularly by filling cracks and moderate depressions in the roadway surface not filled by mere levelling of the liquid oil after a spraying operation alone. The squeegee is towed behind the oil spraying truck, extending across the roadway surface and being maintained on rollers a selected height above the existing pavement. The squeegee pools the oil ahead of its blade while forming a uniform coating on the roadway surface over which the blade has passed. The pool of oil fills cracks and moderate depressions in the roadway surface directly, and thus avoids loss of uniformity in the height of the top of the oil coating. Aggregate is then spread over the roadway and tamped or rolled into the oil, which hardens about the aggregate to form a new, smooth roadway surface.
