Filed: 1990-10-09
Granted: 2002-07-30
Abstract: A medication dispenser includes a reusable container adapted to receive one or more disposable multicompartment liners for sanitary storage of medication out of contact with the reusable container. The open-topped compartments of the liner are closed by individual covers which are locked onto the container with a fracturable tab which must be broken to open a compartment. The covers are designed to form at least a Class B closure with the liner compartments for tamper-proof sanitary air-tight storage of a patient's medication. When the liners are removed, the broken tabs from the covers may be dumped from the compartments.

Title: Computer user interface
Inventor: WOLF RICHARD J
IPC: G06F3/0481
Filed: 1990-10-09
Granted: 2000-09-26
Abstract: A computer user interface that comprises a system and methods to provide a control hierarchy, control marking, a hybrid grammar, and resized and/or repositioned dialog boxes. Control hierarchy divides controls, assigns each control a label, displays the labels according to a design hierarchy, and operates on the controls according to a functional hierarchy. Control marking distinguishes controls, via addition of graphic elements or changes in labels--referred to as glyphs. Hybrid grammar simultaneously allows a user to specify operations and data objects in a noun verb relationship or verb noun relationship. Finally, resized and/or repositioned dialog boxes enable a user to select a control that requires selection of data objects that are possibly obscured by the dialog box.

Title: Container scale
Inventor: WIRTH JOHANNES
IPC: B65F3/02
Filed: 1991-12-05
Granted: 1996-10-01
Abstract: The present invention concerns a process and a device for carrying out the process for weight determination of the contents of containers (5), for example for garbage.  Two swivel arms (2) that are lifted by hydraulic devices (3) are mounted on a garbage collecting vehicle (1).  The container (5) is carried by a fork (4).  Integrated into the swivel arm (2) is a force measuring apparatus that comprises two flexural members (7) supporting the main load, two spring tongues (8), and a force transducer (11) that is installed between two stilts (12) between the spring tongues (8).  The flexural members (7) and the spring tongues together form an elastic stepdown; the force transducer (11) thus only measures that part of the total load flowing through it as given by the stepdown. Further, a gradient meter (16) is mounted on the swivel arm (2), that has the same action line W as the force measurement device integrated in the swivel arm (2).  In this manner, the measurement of the weight of the container (5) is very extensively independent of the gradient. The weight of of container (5) is calculated in known manner by two "total weight - tare = net" weighings.  In order to exclude the influences of elastic prestresses, the angle range over which it is measured is limited to a preset degree.  The container (5) is inserted in the fork (4) in the position ?, position ? is the measuring position, and the container (5) is emptied in position ? (Figure 1).

Abstract: A method and product for sterilizing and drying waste products such as plant sludge, animal excrement and process wastes wherein the waste material is first settled or dewatered to a moisture content between 4% to 60% and then blended in blender (1) and reacted in reaction chamber (3) with alkaline earth metal oxides in the presence of an atmosphere of carbon dioxide, and in the absence of the oxygen. After the sludge is blended with the alkaline earth oxides, the carbon dioxide is removed so that air or oxygen will contact the blended constituents. A violent exothermic reaction takes place between the water in the constituents and the alkaline earth oxides, causing a rapid rise in temperature of the constituents and thus sterilizing the constituents to produce a safe and usable end product.
