Abstract: A skin incision device has a casing with a bottom surface and a slot formed therein, a cover positioned on the casing and slidable in a direction toward the bottom surface, a blade positioned in the casing adjacent the slot, an actuator cooperative to a position between the cover and interior of the casing, and a carriage. The actuator engages the blade by its horizontal displacement triggered by slidable movement of the cover toward the bottom surface of the casing. The carriage element guides movement of the blade between a pre-actuated position and a post-actuated position. The blade extends outwardly of the bottom surface with a fixed depth of cut during a horizontal movement of the blade through the slot.

Abstract: A skin incision device including a housing having a bottom surface with a slot formed therein, a top positioned on said housing and slidable in a direction toward the bottom surface, a blade pivotally positioned in the housing adjacent said slot, and a spring cooperatively positioned between said top and an interior of the housing. The spring is actuatable by the slidable movement of said top toward the bottom surface of the housing. The spring moves the blade between a pre-actuated position and a post-actuated position.

Abstract: A bleeding time testing system including a bleeding time tester having a cutting blade and a switch actuator, and a tripper affixed onto the body of the tester and cooperative with the switch actuator. The tripper includes a housing, a slide frame slidably interconnected to the housing and having a surface cooperative with the switch actuator, and an actuator button mounted on the housing and cooperative with the slide frame. The actuator button is positioned so as to cause the slide frame to move to the activated position when the actuator is moved downwardly. The actuator button is positioned directly above a centerline of the cutting blade of the tester.

Abstract: A method of in situ electrophoresis of biological samples has the steps of preparing a sample plate and a gel plate, applying reagent onto the gel plate, moving an applicator to the sample plate so as to receive a sample onto the applicator, moving the applicator toward the gel plate such that at least a portion of the sample is loaded onto the gel plate, electrophoresing the gel plate, staining the gel plate and scanning the stained gel plate so as to electronically analyze a band in the gel of the gel plate.

Abstract: An automatic electrophoresis machine is provided with a path for refrigerated air to pass over the agarose gel of a support medium during the time that electrophoresis current is applied to the support medium. Such apparatus is also provided with means for applying longitudinal electrophoresis current through the gel of the support medium during one time and applying lateral electrophoresis current through the gel of the support medium during another time.

Abstract: An electrophoresis machine is disclosed in which after a microporous support strip and a sample plate are placed in the machine, all electrophoresis processing, scanning and densitometer functions are automatically performed under computer control. The machine includes apparatus for automatic pipetting of liquid samples from the sample plate to the surface of the support strip, apparatus for applying electrophoresis current to the strip while simultaneously cooling it, apparatus for applying and spreading flourescent staining reagent to the strip, and apparatus for incubating the strip and subsequently drying it. A T.V. camera, mounted to a flourescent scanning box enclosing the application plate, in cooperation with digital processing equipment, electronically scans electrophoresically longitudinally displaced components of the samples for determining relative component densities. An alternative scanning apparatus including a collimator and photomultiplier is also disclosed.

Abstract: A fluid proportioner is disclosed that will divert a volume of fluid to two or more containers in relatively equal amounts without the necessity of measuring or weighing the fluid to accomplish division. The proportioner consists of tubular member ending in a closure. Two additional smaller tubular members extend into the larger tubular member. These two smaller members have ends interior of the first tubular member that are cut on an angle.
