  • Patent number: 7439457
    Abstract: The higher the reading of relative density, liquid weight per unit volume, of pieces of produce such as fruits, the juicier the piece of produce is. By comparing a number of pieces of produce of the same type and species and ranking them, the juiciest pieces of produce may be easily selected and purchased by a shopper. An arrangement of linkages and a sliding spring element creates a device with two inputs, one input being proportional to the volume of the produce based on a representative diameter, and the other input being an approximation of the weight of the produce based on the deflection of a spring. The two inputs are mechanically combined to create one output indicative of density, and thus juiciness, and a pointer is employed whose deflection is proportional to the quotient of the weight and volumetric inputs of each piece of produce tested by the shopper.

    Abstract: A wheelchair scale is provided wherein triangular or trapezoidal box-shaped members are used for forming a support base having a truss structure. The box-shaped members are formed in advance by welding, and are then welded together. Since the welding processes can be performed separately, work efficiency is improved. In addition, since the support base has a truss structure, it supports a large amount of weight without deflection, even though its thickness is relatively small. In addition, the weight of the support base is reduced compared to a conventional base having a pipe structure. Furthermore, because the height of the support base from the floor is reduced compared to a typical conventional structure, a wheelchair can be easily moved onto the support base.

A loading stage (1) arranged to cooperate with the load receiver (10) has one or more weight-placement devices (5) designed so that the load receiver (10) can reach through the weight-placement device (5) without touching the latter. The loading stage (1) and the load receiver (10) are moveable up and down in relation to each other. The weight-placement device (5) is suitably configured to support the different weights (13, 14, 15, 16). The load receiver (10) and loading stage (1) are used in a mass comparator for testing weight standards with a high degree of precision.

  • Patent number: 6797894
    Abstract: A body weigh scale that is formed of a fiber-filled, polyester thermosetting polymer material that is sufficiently rigid so that it may house strain-gauge load cells therein, and yet not significantly deflect under load. The fiber-filled, polyester thermosetting polymer material provides an attractive surface after molding. The fiber-filled, polyester thermosetting polymer material has extremely low shrinkage rates so that the outer pattern and shape of the scale is not affected by the forming of very thin cross sections adjacent to thick cross-sections. In addition, the fiber-filled, polyester thermosetting polymer material is sufficiently rigid to permit a body weigh scale to be constructed having a low profile with integral load-receiving platform and strain-gauge load cell receptacles. The rigidity of the fiber-filled, polyester thermosetting polymer material provides sufficient structural support for operation of the strain-gauge load cells without deflection of material at the receptacles.

  • Patent number: 6777625
    Abstract: A balance including a weighing pan (2; 32), a weigh sensor (8; 38) with a housing (1; 31) enclosing the weigh sensor, and an antenna (7; 37) configured to communicate with a transponder (4) that is, e.g., associated with or attached to an object being weighed (3). The antenna (7; 37) is arranged in a horizontal plane in or below the weighing pan (2; 32) and the weighing pan is preferably made of an electrically poorly conductive material. As a result, the antenna is almost invisibly integrated in the balance and does not interfere with the placement of the objects being weighed on the balance.

  • Publication number: 20040129462
    Abstract: A weighing pan for a comparator balance has a surface coated with a polymer lacquer. The coated surface is distinguished by a moderate hardness and increased levels of sliding friction and adhesive friction. By adding anti-static agents, the surface coating can be made sufficiently conductive to avoid electrostatic charges. The coating is resistant to solvents and to the kinds of fluids that are used to perform density determinations.

  • Publication number: 20040055790
    Abstract: A method is provided for weighing a series of mail pieces such as letters, flats or a mixture thereof, that are being conveyed through a weighing module. Each mail piece has a length which falls within a range bounded by a maximum length and a minimum length. The mail pieces are conveyed through the weighing module at a substantially constant speed while maintaining a minimum gap between successive mail pieces as the mail pieces pass through the weighing module. The weight of each mail piece is measured during a measurement time when that mail piece is the only mail piece moving on the scale. The scale is sized so that measurement times for mail pieces between the maximum and minimum lengths will vary.
