Abstract: A hand held device (10) for measuring automatically the Hormonal Quotient and correlated hormonal status of an individual, providing a measure of index finger for ring finger. The device (10) includes a base (30) upon which a concentrically arranged disc (40) is rotatable mounted by a central fastener (11). The base (30) carries a ruler face (32), a first finger-length logarithm scale (36), a Hormonal Quotient logarithm scale (38) and an arrow indicator of the gonadal hormone exposure index (39). The disc (40) carries a second finger-length logarithm scale (42) and the Hormonal Quotient arrow (44). When scales (42) and (36) are properly aligned the Hormonal Quotient arrow (44) inserts automatically into the resulting Hormonal Quotient in the Hormonal Quotient scale (38) and the correlated gonadal hormone exposure (39).

Abstract: An alignment calculator circular slide rule device and associated method for determining shimming requirements for a drive unit to be coupled with a driven unit in angular alignment therewith. The circular slide rule device utilizes drive unit support separation data, coupling structure diameter, and measured angular offset values, to determine shimming requirements for angular alignment of the drive and driven units, by shim addition or removal to the supports of the drive unit.

Abstract: Disclosed is a manually operable calculator for determining a fourth value on the basis of three variables. According to one example, the calculator is used to determine the total storage available for a recording medium consisting of several units, such as hard disks or magneto optical disks. Specifically, values for total storage are displayed in response to inputting the capacity of each disk, the number of disks and the data recording rate. According to the invention, the calculator comprises a slide member upon which two rotating wheels are mounted along a common axis of rotation. The slide and wheels each have indicia corresponding to the three variables printed thereon. The indicia on the wheels is selected by rotation while the indicia on the slide is selected by moving the slide within a sleeve having openings formed therein.

Abstract: The amount of recording time remaining on a partially recorded videotape cassette (11) is measured by fixing the position of a body member (17, 117) relative to the hub (14) of a cassette reel, and moving a pointer (24, 120) to point to the outermost layer (33) of tape (12) wrapped around the hub (14). Movement of the pointer relative to the body member causes corresponding movement of an index (38, 145) relative to a time scale (39, 125), so that the remaining time can be read off the scale. The pointer is coupled so that small movement of the pointer relative to the body member, causes large movement of the index relative to the scale. In one embodiment, a transparent disc pointer (17) is coaxially attached to a transparent disc body member (24).

Abstract: An apparatus for identifying the optimum jet for a carburetor which includes a general annular first member having a plurality of first graduations disposed about a peripheral portion thereof, a general arcuate second member having a plurality of second graduations disposed for cooperation with the first graduations, and members coupling the first and second member permitting relative rotation and selective alignment of the first and second graduations. One of the plurality of graduations are arrayed on a linear scale corresponding to relative air density and the other of the plurality of graduations being arrayed on a scale corresponding to respective jet flow and or identifying numbers. The members coupling the first and second members may include a plurality of arms disposed at angularly space intervals. There may be three such arms and they may be fixed to the arcuate member. The annular member may include an offset peripheral portion that is nested between with the three arms.

Abstract: A directional plotter for underwater searches, land searches, land orienting, or the like includes a pair of first and second relatively rotatable discs with the first disc including first, second and third concentric sets of compass degrees in radially adjacent relationship to each other. The second disc includes first, second and third sets of apertures associated with the first, second and third concentric sets of compass degrees. The two discs are relatively rotatable such that different search patterns can be established by rotating the discs relative to each other and viewing the required degrees for a particular search pattern through the associated apertures.

Abstract: A manometric instrument for use with air bottles of an underwater respirator for underwater diving, comprises a sealed casing having a transparent closure cover; a first fixed scale fixed within the casing for indicating pressure and having graduations based on a first unit of measurement; a second fixed scale fixed within the casing adjacent the first fixed scale for indicating pressure and having graduations based on a second unit of measurement; either the first or second units of measurement expressing units of length, and the other expressing residual pressure of air in the air bottles; an adjustable fixed scales; a first movable scale fixed on the support element and having graduations based on the second units of measurement and differing from the second fixed scale; a second movable scale fixed on the support element for indicating an ascent time as a function of either the depth under water and the residual pressure, when the support element is adjustably displaced such that a value on the first mova

Abstract: There is disclosed a marine navigational calculator device of the slide rule type whereby tidal depths over bottom structures may be determined as a function of the time of the tide or time of calendar day and whereby the entire time span available to a mariner to successfully negotiate such charted bottom structures for a given tidal flow is visually presented.

Abstract: A device for selection of compressors, condensers, expansion valves, and evaporators for air conditioning or refrigeration systems.

Abstract: The disclosure embraces a manually operated weight and balance calculator for use with a slide card containing a graphic display of the weight-balance tolerance characteristics for a particular type of aircraft; the calculator includes a carrier channel for movably supporting a card in a selected position; spaced apart arcuate portions are provided for rotatably retaining a flat disc member; the disc member is provided with an outer rim portion which carries markings thereon alignable with markings formed on one of the arcuate portions; the disc member is provided with a central portion which is transparent to permit observation of a card supported by the calculator; the transparent portion is also provided with a plurality of parallel slots which permit access to the card carried by the calculator for the purpose of placing a series of markings on the card which are characteristic of the magnitude and position of the loads being carried by the aircraft and which will permit visual observation of the effect o

Abstract: A stock trend indicator and method of using is disclosed. The manipulable instrument is used with a standard stock chart to forecast an evaluation of future stock behavior.

Abstract: A circular clock face bearing time indicia equally spaced in a concentric relationship thereon providing a base to support and correlate time quantity indicators. A plurality of arcuate segmented indicators marginally disposed along the perimeter of the face are manually positionable to visually display certain combinations of time indicia corresponding to mandatory work hours, and a plurality of sector indicators slidably supported on the inner portion of the face are manually positionable to visually indicate certain combinations of time indicia corresponding to employee work time. The sector indicators and segmented indicators are cooperatively organized for visually indicating proper correlations of time combinations.

Abstract: The present invention relates to a time card computer that is adapted to compute or calculate the total time worked by a worker over a specified time period and in the process compensates or subtracts for interim time out periods. The time card computer of the present invention is of the circular or disc type and includes a stationary total time worked scale, a movable time reference scale disposed radially inward of said total time worked scale and a movable time out or subtracting scale disposed radially inwardly of said time reference scale.In computing the total time worked by a worker over a specified period of time, the time reference and time out scales are indexed relatively to the stationary total time worked scale.
