Title: Weighing system for series of moving objects or materials - uses strain gauges, reference accelerometer and calculator to determine total batch
IPC: G01G19/18
Filed: 1988-06-02
Abstract: The system is designed to weigh objects as they are being transported from one place to another in a mechanical grab. Incorporated in the grab are four sensors: three strain gauges and an accelerometer. The outputs of the strain gauges are summed and fed to a signal converter which filters, samples and converts the signal to digital form. The digital signal is then transmitted to a remote receiver. The accelerometer output is processed in a similar way. The received signals are fed via a comparator to a calculating device which produces a filtered output for the weight at that instant. At the same time the signal is fed via movement-compensating circuits and a memory to an accumulator circuit which produces an output proportional to total weight of objects moved.

Patent NL-9300139-A (NL)
IPC: C08K7/26
Filed: 1993-01-25
Abstract: A porous and spherical silica is recovered in high yields from a neutralized product of an alkali silicate obtained by using an acrylamide type polymer as a coagulation growing agent, and the above silica is reacted as a precursor with a metal compound of the Group II of periodic table in an aqueous medium to obtain amorphous or fine, laminar and crystalline porous and spherical silica or silicate granules having a high degree of true sphericality, a symmetrical grain size distribution and a refractive index over a range of from 1.4 to 1.7. The porous and spherical granules have a primary grain diameter of 0.3 to 30  mu m as observed through an electron microscope, have an apparent specific gravity of from 0.05 to 0.5 g/ml, and are cheaply obtained in high yields, and can hence be used as a filler for various paints and resins. In particularly, the granules excellently disperse in the resins, have a refractive index close to those of the resins, are not crushed during the kneading with resins or extrusion, or do not damage the apparatus. The films obtained by using these granules exhibit very excellent transparency, anti-blocking property and scar resistance. Moreover, the porous and spherical zinc phyllosilicate type granules having fine grain sizes and symmetrical grain size distributions, are excellent in their odor scavenging property and sweat controlling property.
