Abstract: A vehicle system includes a vocational vehicle, a tag, and a data management controller. The vocational vehicle includes a chassis and a body. The chassis includes a first subcomponent. The body includes a second sub component supported by the chassis. The body defines a receptacle. The tag is attached to at least one of the first subcomponent and the second subcomponent. The tag includes an identifier that encodes tag data. The data management controller is configured to receive tag data associated with the tag. The data management controller is configured to provide material from a tag database stored by the data management controller to a user device based on the tag data. The material is associated with the at least one of the first subcomponent and the second subcomponent.

Abstract: Food consumption monitor comprising a simple mechanical calculator integrated into a diet guidebook. The calculator includes a manually operable rotary dial with a scale pointer on it, a base for the dial, a means for rotatably mounting the dial to the base, a finger stop attached to the base near the dial, and a set of numerals which are printed in consecutive order on the base near the dial and which are equidistant from the dial's rotary axis. The dial has a set of finger holes or dimples which are equidistant from the dial's rotary axis. The dial's scale pointer is a visually distinctive feature on the dial, such as an annular rim around one of the holes, which rotates with the dial in close proximity to the set of numerals. The base includes a molded plastic casing which partially encloses the dial. This casing includes an axle, a stationary hub, and a support arm for rigidly coupling the hub to a wall of the casing, wherein these three components are the means for rotatably mounting the dial.

Abstract: A number wheel counter has a worm wheel connected with the least significant number wheel. A worm gear engaged with the worm wheel is mounted for both rotational and translational movement about a spindle. Cam means are provided such that as the worm gear is rotated, it is also displaced bodily by the cam means so that the worm wheel remains unmoved. At the end of a defined travel of the cam means, the worm gear is returned rapidly to a rest position driving the worm wheel in the manner of a rack and pinion. In this way the number wheels are driven intermittently with the time interval during which the number wheels are between discreet number positions being minimized.

Abstract: A new type of bioclock calculating device for the human body comprising a ring, a set of discs and some accessories. They are marked with data graduation, age graduation and curves showing the cycles of physical, emotional and intellectual (PEI) rhythms. When superimposed eccentrically set into planetary revolutions, the discs will provide instant information about an individual's PEI rhythms on any day in any year and show the continual distribution of the curves over many years. It may also be used for a comparative study of PEI rhythms between two persons.

Abstract: An electrochemical grinding process is controlled by the use of a feed-rate indicating device which calculates and displaces the feed-rate (V) of a workpiece and a grinding wheel which are displaced relatively toward one another. The feed rate V is determined by the relationshipV = A p/h + B/.sqroot.hwhere h is the cutting depth, p is the force for driving the wheel electrode in terms of nominal kilowatt power rating P per unit width w of the cutting area, and A and B are constants. These constants are determined between values of A of 150 to 156, exclusive, and values of B from 5.8 to 11.4, exclusive for current densities of 60 to 80 amperes cm.sup.2, respectively, by extrapolation.
