Abstract: A weighing scale (10) has a display/operating unit (20), a scale platform (30), an electronic system (60) for the control of the scale (10), and a pedestal (40) that connects the display/operating unit to the scale platform. The pedestal contains a pedestal chamber (41). The pedestal also has a pedestal opening (42). A carrier element (70) is arranged in or at the pedestal chamber. At least parts of the electronic system are arranged on the carrier element, and the parts of the electronic system which are arranged on the carrier element can be at least partially taken out of the pedestal opening for servicing.

Abstract: A draft shield for a balance that has a balance housing has a rear wall and a front wall panel arranged in a fixed position to the rear wall, at least two side wall panels and a top cover. The rear wall and the front wall panel are connected to a base. The base has a locking device and the balance housing has a complementary locking element. The locking device and the locking element cooperate with one another to releasably attach the draft shield to the balance housing, wherein the locking device and the locking element are configured to release the draft shield without moving the draft shield.

Abstract: A load indicator conversion system is disclosed for converting a scale having a mechanical measuring system, such as a conventional portable beam scale, into a scale having an electronic measuring system for providing an electronic display, such as an LCD display, corresponding to the load applied to the mechanical load receiver of the scale, such as the scale platform [104], which is mechanically linked via the beam load rod assembly [110] and an s-hook arrangement [150] to a load cell transducer [1]. A single common temperature sensor is employed adjacent the load cell and the associated electronics to provide information on the variations in temperature to the microprocessor for enabling temperature compensation to take place.

Abstract: A weighing device includes a housing disposed on an upper end of a post, a displayer disposed on the housing, a piezoelectric element disposed in the housing and having one end located above the opening of the housing, an air bag disposed on a base, a tube coupled to the post and connected to the air bag, and an expandable member disposed on an upper end of the tube for pushing the piezoelectric element when an object is put on the air bag. A signal corresponding to the weight of the object is generated and displayed on the displayer.

Abstract: A modular construction system is provided for building impulse machines having a computer weight module that is responsive to a floor scale assembly. The weight module is supported on a pedestal which is attached to a base plate of the floor scale assembly. The pedestal is hollow to accommodate an electrical cable connecting the impulse module to load sensing means located within a pressure pad of the floor scale assembly. Additional impulse modules having different themes can be attached atop the pedestal along with the weight module by use of an adapter plate. Thereafter, the type of impulse modules utilized in the impulse machine can be changed by detaching selected impulse modules from the adapter plate and substituting new impulse modules therefor. Moreover, a different number of impulse modules can be supported on the pedestal by interchanging the adapter plate with another, differently sized adapter plate designed to accommodate a larger or smaller number of modules thereon.

Abstract: A chest high balance beam scale including balance indication means on the head of the scale which is observable from above to allow the user to determine when the beam of the scale is in balance. The head portion of the scale is fabricated of molded plastic with the balance beam being a rectangular frame which forms part of an enclosure for the balance weights and balance indicator.

Abstract: An electronic balance devised so that the weighing pan of the balance may settle down fast to make the balance indicate a correct value of measurement quickly without being long disturbed by the air turbulence arising when the door of the weighing pan protecting chamber of the balance is opened and continuing for a while after the door has been closed. This electronic balance is provided witha heater on the base portion of the weighing pan protecting chamber so that the heater is located just below the door of the chamber. The heater generates hot air streams rising upward therefrom along the outer surface of the door. When the door is opened, the air streams play a role of an air curtain to prevent a possible air exchange between the hotter chamber warmed by the electronic circuit of the balance and the cooler surrounding atmosphere.

Abstract: In an electromechanical weigher to be used in areas subject to explosion hazards, the electronic indicator ledge and the weigher apparatus or weighing system is constructed explosion proof in an intrinsically safe manner, and the power supply in the case is on all sides partitioned by means of bulkheads, and the free space enveloping these constituents is filled with an explosion-impeding granulate e.g. of quartz. For the use as dosing weigher for prescription weighings in such areas subject to explosion hazards, the indicator ledge is constructed by means of a hollow support engaging the case above the weigher dish and above a tare vessel of the usual height to be put on the weigher dish, as horizontal indicator constituent running approximately parallel to the weigher back, and the indicator constituent is tiltable at the support about a horizontal shaft in which structure the electric supply lines are passed from the indicator edge through the hollow support, into the inside of the case.

Abstract: A weight scale is made splash resistant from being splashed by liquids. Means is also disclosed for making the weight scale vapor resistant. The scale includes a housing on a column on a base and a force-to-electrical output transducer is mounted enclosed within the upper housing. A rod is enclosed within the column and is moved longitudinally therewithin by being connected to a lever system connected to the pan or platform on which the weight is received. The rod acts on the transducer and an electronic circuit provides an indication of the weight on an indicator also in the housing. Liquid splash-resistant means is positioned between the bottom of the base and the transducer within the housing for splash-resistant protection of this transducer. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: A platform type weighing scale is provided having a horizontally disposed base, a vertically disposed column mounted on an extension of said base with a hollow base portion in said column and a load beam mounted in said hollow base portion connected through a lever to a weighing mechanism beneath said platform, said load beam having one or more electrical strain gauges mounted thereon which are connected to a read-out meter mounted on said column to show measurements in units of weight. The housing for the read-out meter is preferably adapted to rotate horizontally or to tilt from the vertical or both and can also be removed so as to provide a number of options including a high level scale, a waist high personal scale, or a desk top or wall mounted remote unit.

Abstract: A weighing scale especially adapted for use as a pediatric or infant scale having a mechanical leverage weighing structure with a high degree of sensitivity and low friction and hysteresis coupled with a compatible electronic measuring system and a digital read-out system is provided wherein a base has a weight responsive movable platform mounted thereon, a housing mounted on the base behind the platform, said housing forming an enclosure extending upwardly substantially higher than the platform with weighing mechanism inside the housing connected through an opening in the base to the platform, the weighing mechanism including a variable inductance transducer which generates a signal in response to weight on the platform and a read-out unit mounted on the top of the housing, said read-out unit displaying weight measurements and being operable in response to said signal.
