Abstract: A golf club survey instrument includes a weight scale and a variably positionable fulcrum, enabling the instrument to be used determine the total weight of a golf club or the weight of each of its separate components, the swing weight of the club, and the center of gravity of the club. A linear scale also provides for the determination of the length of the club, or club components such as the shaft, grip, etc. The instrument comprises a base having a weight scale affixed at one end thereof, with the scale including a golf club grip retainer thereon positioned to place the end of the grip at the origin of the linear scale. The retainer also limits oscillations of the club, thereby providing for the rapid and accurate determination of the center of gravity of the club when balanced upon the fulcrum of the instrument. The base also includes a linear track therein and parallel to the linear scale, with the track providing for the adjustable positioning of the fulcrum therein.

Abstract: For mailing use, a balance scale devoid of springs, electrical components, gradations, indicia and moveable pointers. Said scale is designed for use in determining postage due for UNITED STATES POSTAL SERVICE:1. FIRST CLASS MAIL wherein postage fee is based on one ounce minimum weight and one ounce weight increments up to and including eleven ounce2. PRIORITY MAIL wherein there is a single fee for mail weighting more than eleven ounces but not more than two pounds.

Abstract: A coin scale for measuring weight of a mailing material comprises a scale section and a base section situated under the scale section. The scale section includes an elongated arm, a coin receiving member formed at one end of the arm, a mail receiving member formed at the other end of the arm, and a first supporting device situated between the coin receiving member and the mail receiving member. The first supporting device is provided with a plurality of supporting points. The base section include a stand and a second supporting device formed on the stand. The second supporting device rotatably engages one of the supporting points and supports the arm as a fulcrum of a balance. In at least one supporting point, weight at the mail receiving member increases step by step corresponding to the particular weight zone of a mailing material as one coin is added in the coin receiving member.

Abstract: A high speed mechanical weighing system includes a series of article holders carried by chains and forming a flexible conveyor in which the holders are individually pivoted for movement between carrying and discharging positions. The mechanical weighing devices are spaced along the path followed by the holders with stationary guides alongside the holders which are periodically interrupted to accommodate vertically movable weighing guides. The holders have support members which bear either upon the stationary guides or upon the weighing guides. The holders are closely spaced so that a rearmost support member of a leading holder is positioned to laterally overlap but not bear upon the foremost weighing guide member of a weighing station at which the trailing holder is being weighed. The weighing guide members are sufficiently long as to effect accurate mechanical weighing even if the holders are traveling at high speed.

Abstract: A small mechanical weighing scale capable of weighing relatively light, flat articles such as envelopes. The scale contains a slidable pullout flexible beam that is adapted to hold a thin flat article. The tape will break away in accordance with the weight of a held article as the tape is extended from the housing of the scale.

Abstract: A proportionate balance is provided with which an arbitrary amount of one component can be proportioned with a precise weight of another component. A rocker member supports the balance and eliminates the need for knife edges or other typically fragile pivot points.

Abstract: The sensitivity of a balance beam having unequal arms used to detect and measure phenomenon which exert low energy mechanical forces includes a U-shaped beam area having a horizontal slot therein and a pivot post having a vertical slot which registers with the horizontal slot. A fastener, such as screw and wing-nut passes through the slots to releasably fix the pivot post to the fulcrum area in a selected horizontal and vertical position. The selected position is the optimum point of equilibrium of the beam that is determined when the horizontal fulcrum's bottom knife edge passes through center of gravity of the beam. Pivot post has a blade thereon which extends perpendicular to the balance beam and rests on a pair of fulcrum supports. The fulcrum supports are vibrated by a didder device to enhance sensitivity of the balance beam.

Abstract: The device for metering a powdered, granular or liquid product, comprises a metering chamber (1) which has a variable volume.The metering chamber (1) comprises a wall (2) which is movable within said chamber. The latter is connected to a lever (4) pivotally mounted on an axis (5). The end of the lever opposite the movable wall (2) is associated with first means (9) allowing the lever to be pivoted about its axis and with second means (10) allowing the ratio of the arms of the lever (4) on either side of its pivotal axis (5) to be varied.For use especially in an apparatus for preparing coffee and for regulating the number of cups and the strength of the coffee.

Abstract: A scale includes an arm system movable about and fixedly secured to a fulcrum. An output detector is coupled adjacent to one end of the arm system. A load structure is utilized to position an item thereon which is to be weighed by the scale. A strain sensor is fixedly connected adjacent the other end of the arm system and the load structure. The strain sensor and fulcrum are formed of resilient material.

Abstract: Pressure converter for use between a hydraulic load sensing element and a gauge or other device to indicate a property of the load directly in desired units. The pressure converter comprises a first force-pressure transducer connected hydraulically to the sensing element, a second force-pressure transducer connected hydraulically to the gauge, and a pivotally mounted beam having first and second arms connected to the transducers for producing a pressure in the second transducer corresponding to the pressure from the sensing element and the relative lengths of the arms. In one embodiment, the beam pivots about an adjustable fulcrum member which can be moved axially of the beam to vary the lengths of the arms and provide the desired calibration. In a second embodiment, the pivot for the beam is provided by a flexure plate, and the lengths of the arms are adjusted by changing the distances between the load cells and the flexure plates.
