Abstract: Scale with a digital display and an additional analogue display, the latter comprising at least one group of optically activable elements forming a row, each element corresponding to a value range of results of weighing operations, the length of the higher order range being at least ten times the length of the lower order range, all elements corresponding to value ranges lower than the value range to be displayed being activated.

Abstract: A force and mass meter using two transversally vibrating preloaded strings as the force sensitive members. The two strings are placed in a transverse magnetic field and are caused to vibrate by means of an exciting current flowing across them which is delivered by one exciter each. The exciters consist of a metering bridge, and an operational amplifier deriving the exciting current from the error signal measured across the bridge. Mutual interference of the two exciters is drastically reduced, when the point of common potential of the two exciters is connected with at least one conductor to each of the exciters.

Abstract: A casing for an electrical apparatus having a front wall and a back wall, an electrical plug on said back wall, said casing having a base, a jacket in which said apparatus is mounted, said jacket being detachably fixed to said base, a passage in said base, a set of cables through said passage, a plug socket fixed to said cables, said back wall, said jacket and said base forming a water sealed room, said plug and said plug socket being within said room when said jacket is fixed to said base.

Abstract: A mass and force meter employing levers to carry the load support which levers in turn are supported by a frame with four legs. Both frame and load support are constructed to deform under the weight of the apparatus itself, so the meter is in a statically defined position even if positioned onto an uneven floor or support structure.

Abstract: A mass and force meter having a frame, a load support and a digital computing device, a first and a second electrically excited, transversely vibrating string, first transmission elements transmitting the mass or force to be measured to said strings, second transmission elements transmitting a pre-loading force to said strings, so that the resultant frequency variations caused by the application of said mass or force are used in the computing and display device for computation of the magnitude of said mass or force, said first transmission elements having a first and a second branch, a first guide fixed to the frame, said first string having one end fastened to said frame and the other end connected to one end of said second string, to said first guide and to said first branch of said first transmission elements, a second guide fixed to the frame, the other end of said second string being connected to said second guide, to said second transmission elements and to said second branch of said first transmission

Abstract: A mass and force meter comprising a frame, a load support, a measuring system, stops on the frame and on the load support, guides for vertically and parallel guiding the load support, at least one measuring cell in the measuring system, supporting elements mounted between the load and the measuring cell and transmitting to the cell substantially vertical forces only, one of the guides being elastically deformable under the action of horizontal forces acting on the load support, the elastic deformability of the guide increasing abruptly for a pre-determined value of the horizontal forces, the stops limiting the horizontal movement of the load suppot under the action of the horizontal forces exceeding the pre-determined value.

Abstract: In a mass and force measuring instrument comprising a load support, load-compensating means with very small travel, transmission elements transmitting a force depending on the load to the load-compensating means, display means, at least one linearizing spring whose force varies continuously and acts on the load-compensating means in a direction parallel to that of said force depending on the load, said linearizing spring being active only in a part of the measuring range and means to adjust the characteristic line of said spring.

Abstract: Balances having a reference mass and means for compensating for thermally induced errors such as shift of the zero-point and change of steepness in the characteristic of the balance. Bimetallic members are fastened to movable parts such as levers or other force transmitting members, or to the reference mass, and function as supports for masses acting as compensating masses. This allows for offsetting the two kinds of errors independently. Moreover, the bimetallic supports can be mounted on adjustable members, e.g. rotary disks or the like, to further adjust the desired amount of correction.
