Abstract: A Biorythms analog computer-calendar is provided to display without computations the level of the physical, the emotional, and the intellectual biorythms of a human body. The level of the three biorythms appears on display in analog and digital forms for any dialed calendar date, if the computer-calendar is set initially with the individual's birth date. The analog elements used to register the three biorythm levels are drums attached to gears with a number of teeth equal or proportional to 23, 28 and 33, or to the period of the three biorythms respectively. A calendar arrangement is introduced to create a correlation between the displayed biorythm levels and the calendar date associated with them.

Abstract: An improved safety closure for containers is disclosed; the closure comprises a snap-on cap held in place on a container by a rotary safety ring which must be aligned with the cap in one angular position and pushed downwardly away from the cap before one can remove the cap from the container. The closure is improved by providing an outwardly directed bead on the safety ring which makes it easier to grip and push down (and up) the safety ring. An annular protrusion, added to the underside of the cap, and a circumferential knob, added to the neck of the container, improve the seal of the container. Also, a safety ring and cap assembly which has no lateral opening between the safety ring and the cap is disclosed. This invention describes various ways to incorporate on the closure means for counting the number of uses or doses of the container's contents.

Abstract: Disclosed is a way by which a person may keep track of consumption of pills, or dispensation of other articles. A box receptacle is used to store pill bottles, each marked with a different symbol. Designations of time periods at which pills are scheduled for consumption are marked on the sides of the box, spaced apart so that only one designation may be made principally visible by rotation of the box. Affixed to the sides of the box at the designations are tags corresponding with the symbols marked on the individual bottles, to indicate by type and number, if desired, the pills to be taken. After consuming the pills at a scheduled time the user rotates the box so that the next scheduled time is visible, thereby providing a later reminder if the user forgets if the pills were taken as scheduled.

Abstract: A marine direction finding system is disclosed wherein a rotatable and calibrated dial is placed over a direction indicating dial of a radio direction finder. The radio direction finder indicates direction by illuminating a portion of its indicating dial. The direction of the radial signal received is referenced to a front of the boat which is calibrated as 0.degree.. The rotatable dial is preferably at least semitransparent and is calibrated at a first radius from 0.degree. to 360.degree. and at a second radius also from 0.degree. to 360.degree. but offset by 180.degree.. When a signal is received, the rotatable dial first radius marking is set to a 0.degree. marking on the direction finder in accordance with the current magnetic heading for both.

Abstract: A two-sided portable scoreboard for simultaneously displaying a set of two-digit scores both frontally and rearwardly upon a single setting thereof. A pair of disks is sandwiched between a front and rear plate for each set of scores to be displayed. The disks are axially mounted so that a portion of each overlaps a portion of the other, their centers being positioned so that one is slightly more than a radial distance from the other. At least one of the disks has a transparent center section that has a diameter roughly equal to one-half the overall diameter of the disk. A set of scoring symbols are selectively positioned and uniformly spaced around the circumferential portion of both sides of each disk. Windows, or other viewing portions, are placed in both the front and rear plates so as to allow a desired sequence of scoring symbols to be viewed therethrough as the disks are rotated.

Abstract: A manipulating rotary control device wherein a knob is connected to a dial having associated therewith a hub defining a socket for receiving the end of a control shaft, such as the valve shaft, in a domestic range or the like. The knob may be formed of a light-transmitting synthetic resin and may be hollow so as to permit desired aesthetic treatment of the interior thereof. The knob may serve as an insulating element of the assembly permitting the dial to be made of metal as well as of synthetic resin. The knob may be secured to the dial or hub by suitable means such as heat staking, etc. The hub socket may be closed so as to seal out moisture. An indicator may be associated with the knob which may be selectively movable as an incident of movement of the knob toward and from the wall from which the control shaft projects for providing an indication of the position of the control shaft. The knob may include a clear portion for viewing of the indicator in preselected disposition within the knob.
