A method and apparatus to monitor the weight of a silo or tank is disclosed. The system is adapted to be attached to a leg of the silo and comprises a load cell, a support member anchored to the ground and a lifting device attached to the load cell and to the support member. The load cell comprises two extremities that are attached to the silo leg and comprises an aperture there between. The aperture is preferably threaded to receive the lifting device, such as a bolt. The bolt is rotated using a tool as to induce a movement of the load cell along the axis of the bolt thereby lifting the load cell and the attached silo leg. Strain gauges are attached to the load cell to measure the variation in an electric or optical signal that is translated in human readable data using a monitoring device.

The present invention provides a process for recovering transition metal tetrahalides from a waste stream coming from a catalyst manufacturing process by (a) establishing a mixed stream comprising transition metal tetrahalide and transition metal alkoxyhalides; (b) forming a falling liquid film from the mixed stream of step (a) at a temperature of from 25 to 85 C. and an absolute pressure of from 0.05 to 0.6 bar; and (c) establishing from the film of step (b) a first vapor stream containing from 90 to 100% of recoverable components and a second liquid stream containing about 10 to 80% of titanium haloalkoxides.

An apparatus including a storage tank, a frame positioned at least partially beneath the storage tank, a lever having a first end and a second end pivotally mounted to the frame, a scale system positioned beneath the storage tank, wherein in a first position, the storage tank exerts a force against the scale system, and in a second position, the second end of the lever exerts a force on a bottom of the storage tank such that the storage tank is positioned above, and out of contact with, the scale system.

A system to monitor weight of a reservoir or a structure comprises a load cell which comprises an electrical or optical transducer to provide a proportional signal of the deformation, a load cell base support for holding the load cell on the ground substantially about the axis of the support element of the reservoir, a load cell support adapter to attach the loadcell to the support member of the reservoir. The cell support adapter may comprise an opening or a shouldering anchor aiming at facilitating attachment to a temporary lifting device.

The present disclosure relates to apparatuses and methods for weighing contents of a storage tank. One apparatus for weighing contents of a storage tank includes a load cell and a storage tank. The apparatus further includes a first plate removably attached to the storage tank. The apparatus additionally includes one or more compression springs disposed below and supporting the first plate. Still further, the apparatus includes a platform that includes a second plate, between the first plate and the storage tank, and one or more legs. The second plate engages the load cell. Each leg corresponds to one of the compression springs. Each leg extends from the second plate through a through-hole in the first plate and through a corresponding compression spring to a corresponding foot that supports the corresponding compression spring. The storage tank and the first plate are movable relative to the load cell and the platform.

A device with weighing capability (or scale feature) and also anvil capability (or tapping feature) allows accurate and precise filling of an espresso portafilter with coffee grounds for use in beverage preparation. Some versions switch between a protected mode for anvil use, and a weighing mode for accurate weighing of the portafilter and its grounds, by pivoting the entire load cell into and out of a protected location wherein tapping/shocks do not flex/strain the load cell free end. In other versions, one or more stop(s)/limit(s) are near the load cell free end or associated elements, and the free end/elements move during said tapping/shocks but only to the stop(s)/limit(s), corresponding to a safe amount of strain for the load cell. Also, this way, weighing the portafilter and its contents may continue between taps without switching to a separate protected mode.

A multiple weighing scale includes a first measuring device and at least a second measuring device; both for detecting masses of objects. The weighing scale includes a single measuring plate, which is shared by all the measuring devices, arranged in contact with the first measuring device at least in an initial operating configuration and at least one first mobile structure, for selectively moving the second measuring device so as to selectively cause the second measuring device to come into contact with the measuring plate, in order to allow the measurement to be performed by the second measuring device instead of the first measuring device.
