Abstract: The present invention provides airline travelers with a method of determining baggage weight compliance while traveling, prior to having baggage rejected or additional fees assessed at the baggage check counter at the airport. In a first aspect, a scale is disclosed that comprises first and second attachment points, wherein the scale indicates a relative force applied to the attachment points. In a second aspect, a scale is disclosed which comprises two independent attachment points wherein the scale can display the total force applied to the attachment points.

Abstract: An apparatus for measuring the amount of liquid in a tank mounted within a vehicle. The apparatus includes a tank-mount mechanically coupled to and surrounding the tank to prevent translational movement of the tank, The tank-mount has a plurality of pivoting members allowing only rotational movement of the tank. The members pivot about a common axis, defined by an orifice of each of a plurality of fixed members coupled to the vehicle. The tank-mount also has an extended end positioned on a side opposite to the plurality of pivoting members which extends outwardly from the tank. The apparatus also includes a load cell in contact with the extended end for providing a signal proportional to the load placed on the load cell by the extended end.

Abstract: A scale, especially a bathroom scale, comprises a base (10), a platform (11) and, arranged therebetween, a weighing mechanism comprising a U-shaped supporting bar (34) which is attached to the base (10) and supports indicating elements of the weighing mechanism. The mechanism also comprises two pairs of levers (12, 13) which support the platform (11). All four levers (12, 13) are at one end pivotally mounted on or in the vicinity of the corners of the base (10). The levers (12) of one pair of levers form a V-shaped lever part (15) by extending in V-shape from a plate (14) which is supported by a spring (30) included in the weighing mechanism, the spring being arranged on a longitudinally adjustable upright (31) resting against the base. The levers (13) of the other pair of levers are, at their end (21) operatively connected to the lever part, formed with a downwardly open recess (22) which rests against a corresponding, upwardly open recess (23) in the levers (12) of the lever part (15).

Abstract: Weighing device for weighing a container to be moved by at least one arm system with a lifting device, comprising a support, a lifting arm pivotally connected at one end to the support, and a weighing arm pivotally connected to the lifting arm at one end of the weighing arm adjacent the point of connection of the lifting arm to the support. The other end of the weighing arm detachably supports a container to be weighed. A load cell assembly is disposed and acts between the other end of the lifting arm and the weighing arm adjacent support for the container.

Abstract: A weighing scale includes a hollow casing having a lower base and an upper covering for support an object. A pressure gauge mounted to the base includes an indicator, and a hydraulic pressure sensor connected to the indicator and actuating it in response to a sensed pressure produced by the weight of the object. Four spaced fulcrum posts are mounted to the base. A lever mechanism includes a rear one-piece rod and a pair of spaced front rods respectively and pivotably mounted to the four fulcrum posts. The rear one-piece rod includes a force exerting plate resting on the hydraulic pressure sensor. A transmitting frame provided between the covering and the lever mechanism includes a pair of spaced rods and a connecting rod mounted between the spaced rods which are pivotably mounted to the lever mechanism.

Abstract: A portable low profile mechanical scale is provided having a carriage with spaced side frames each with wheel means at one end and ground support means at the other end, spacers between the side frames holding them in fixed parallel relation, removable wheeled lift means engaging the side frames adjacent the ground support means for moving the side frames, a pair of torsion bars above said side members at two different parallel levels, one adjacent each side frame and supported thereon by triangular links fixed to the torsion bars at one end and supported on the side members at the other, a weigh bed movable vertically between the side frames and pivoted to the triangular links between the torsion bar and support on the side frames, a lever on each torsion bar adjacent said wheel lift means extending transversely toward each other, one above the other, a link connecting said levers midway between the side frames and a connector on the uppermost lever for connecting to a weight indicating mechanism.

Abstract: A portable scale for weighing animals and the like. A weighing platform is suspended on top of two floating crossbar assemblies which are pivotally mounted to opposing edges of a rectangular wheeled base. Each crossbar assembly includes a lever member extending across the rectangular base toward the other lever. The levers are pivotally linked together at the center of the rectangular base such that weight applied to either crossbar assembly from the platform is transmitted to one of the levers which extends beyond the rectangular base. Downward motion of such lever is converted to a weight by a balance or load cell weighing mechanism. A weighing enclosure or basket is provided on top of the platform to confine animals therewithin during weighing.

Abstract: A flexure scale is made of compact, inexpensive construction and includes a load frame which is supported via flexures from a stationary support frame. The load frame includes two oppositely directed beam arms which are displaced when a load is placed on the load frame. The two beam arms are connected together to permit a summation of their displacements and the longer beam arm is secured at the free end to the support frame by means of a spring which proportionally restrains the displacement of the beam arm. A linear variable differential transformer is mounted on the support frame to emit signals corresponding to the displacements of the beam arms to a digital readout means. The electrical output of this transformer is adjusted to produce a fixed output for a standard load.A system composed of a multiplicity of these scales requires only a single read-out means.

Abstract: A platform scale having an interconnected lever type suspension in which all of the suspension links are adjustable for optimum alignment of the mechanism. Each suspension member has an adjustable pin with a V-notch to receive a thin blade type hanger link, each pin having locking means by which the mechanism can be set with all the hanger links accurately vertical, so that no offset loads or drag are applied to the scale. The mechanism is applicable to electronic readout systems utilizing strain gauges or similar force indicating means, or to beam type scale mechanisms with adjustable weights.

Abstract: A low-profile platform scale has a horizontal base, a lower primary U-shaped lever, an upper secondary U-shaped lever, a horizontal platform, and load cell means mounted on the base. The base has a unitary structure including a front pair and a rear pair of modified vertical angle irons connected to the ends of a horizontal shallow rectangular tubing and supporting short inverted channel irons each with one leg shorter than the other, to provide a pair of spaced upstanding portions of the base at the central part of the front and rear margins of the base with a portion of the short flanges and a portion of the long flanges of the pair of channel irons providing mounting means at upper and lower elevations as vertical flat surfaces facing the ends of the scale. These flat surfaces are at two transverse vertical planes.
