Ultramicro balance unit used as sensitive suspension scales

The balance unit consists of an elastic double fibre working twofold as tension and flexing fibre. So that both fibres with their tensional force carry a plate, upon which lie the weighing beam and the load. The mass of which can be as great, as the max. tensile load of the fibre. So that both fibres with their flexing and restoring force sensitively measure and stabilise the out of balance. In a determined sequence, to these masses (m) suspending in a stable balance, new masses (M) are applied from the left and the right. They are adjusted to a determined distance for a determined duration smoothly and left standing, or with approximation the movement becomes slower. After a determined duration, the new masses continue movement, and exchange to the other side in a mirror image position. With the transfer in a new position, after an interval wait, a new position is set up. The strength of the interaction so produced and the speed of movement produced can be controlled to set aim and also regulated.

Load measurement signal transducer arrangement for railway wagon - uses weighing pan and transducer linkage limiting relative motion and change of force direction

A load measurement signal transducer arrangement has a load receptacle and sensor which responds to the force applied to it in the load measurement direction. It is used for weighing railway wagons. The arrangement is designed to guarantee accuracy by preventing contact between the receptacle and the balance structure and by connecting the receptacle to the transducer by a linkage which limits movement of the receptacle tending to change the force direction. Transducers (20) are mounted on a support part (14) having a cut-out (17). The receptacle (10) is connected to the support (14) via a support device (18) permitting no or limited relative motion.

Fluid measurement device

A fluid collection, dispensing and measurement device for use in connection with a blood container, for example, and flexible tubing leading thereto. A hollow balance bar, with mobile spherical weights disposed therein is provided and rapid, forceful cut off of the blood flow through the flexible tubing is achieved when the moment created by the filling blood container, accentuated by the motion of the spherical weights, overcomes the moment produced by a preset adjustable counter weight. An adjustable clamping apparatus allows the fluid collection device to be affixed to a stationary object and subsequently adjusted to a level plane to insure accuracy of measurement. A simple modification of the device allows it to be used as a fluid dispensing device. A full container of fluid can be hung on the modified device and a measured quantity of fluid can be dispensed with cut off being achieved as described above.

Sliding-weight balance

A sliding-weight balance has on its pivotable weighing beam (16) a ballscrew (32), on the spindle nut (48) of which a sliding weight (50) is attached fixedly in terms of rotation. The spindle is connected to a spur wheel (34) which is rotated via an intermediate gear by a spur wheel (36) mounted fixedly on the base, when a handwheel (44) is rotated. The wheels (34, 36) lie in the vertical plane containing the pivot axis (22) of the frame (16). As a result of the use of the ball screw (32), the axial adjusting forces of the sliding weight (50) are very low, with the result that production and assembly errors have no appreciable effects on the weighing accuracy when rotational forces are transmitted from the base to the weighing beam (16). The drive structure can therefore be produced cost-effectively. <IMAGE>

Electronic weighing device having label printer

Abstract of the Disclosure There is an electronic weighing device comprising a weighing apparatus for generating weight data responsive to the weight of a load, a memory having a true value memory area and N data memory areas for time sequen-tially storing the weight data from this weighing apparatus in every sampling cycle, a display device for displaying at least the true value data stored in the true value memory area, and a control unit for storing into the true value memory area the true value data calculated by processing the weight data stored in the N data memory areas in accordance with a display blinking prevention process. When it is detected that the difference between the weight data derived in two successive sampling cycles is a predetermined value or more, the control unit inhibits the display blinking prevention process and stores into the true value memory area the true value data calculated on the basis of the weight data stored in the N data memory areas.

Scale employing wheatstone-type bridges and strain gages

A scale including a rectangular base frame supporting on opposite sides horizontally disposed torsion bars having their central portions secured to said frame and including a horizontal, plate-like rectangular platform superposed to said frame and bars. End portion of said bars support said platform by upstanding, threaded members engaged in said bars, eccentric seats on threaded member heads, and balls on said seats on which the platform rests. General platform leveling can be achieved by full-turn rotation of the threaded members and scale calibration adjustment can be facilitated by less than full-turn adjustment of said threaded members thereby shifting the locations of the balls along the torsion bars. Each torsion bar end portion has an upper and a lower strain gage for a total of eight. Two modified Wheatstone bridges use the strain gages for all resistors of the bridges whereby all bridge resistors are active and the two bridges form the sole electrical means to measure load on the scale.

Modular weighing apparatus

A weighing apparatus comprises a plurality of weighing apparatus modules, each of which includes an elongated platform structure under which lies an elongated frame structure. A load cell is interposed between a downwardly directed area of the platform structure and an upwardly directed area of the frame structure in the region of one end of both structures. A bracing arrangement, which resists relative horizontal movement of the platform and frame structures but permits relative vertical movement, includes a pair of parallel mechanical linkages, one of which is connected at one end to the platform structure adjacent the load cell and at the other end to the frame at a location spaced away from the load cell. For stability, the other mechanical linkage is connected in reverse fashion, namely, at one end to the frame structure adjacent the load cell and at the other end to the platform structure at a location spaced away from the load cell. Similar modules are assembled to form a single rectangular weighing apparatus, with one load cell at each corner by upper and lower tie plates which respectively link adjacent module frame structures and platform structures.
