Title: Blending and conveying system for bulk materials - having diverter valve in feed line to blending silo
IPC: B01F33/40
Filed: 1975-05-31
Abstract: Blending and pneumatic conveying system for bulk solid matls. consists of a fluidised blending and weigh silo located between crude feed storage silos and the plant feed hopper with provision for conveying into and out of the mixing silo. In the pneumatic feed line just before the mixing silo, there is located a diverter valve which is also connected to a recycle line back into the main storage silos. This valve is operated by the original which indicates that the mixing silo has reached its full charge. For use in blending and conveying particulate bulk solids e.g, blending different flour types in a bakery. When a particular blend is being made, it is important that the correct weight is added. In DT 2422963, provision is made that a known additional weight in the line is added when the cut off signal is issued by the weigh hopper. With different matls. this is not consistent. By keeping this quantity very small and recycling the bulk of such matl., the error is reduced to a minimum as in the arrangement claimed.

Title: Shop or store security system - uses two magnetic fields applied to security zone to detect passage of magnetic element on goods and sound alarm
Inventor: HARTMANN ERNST-GERHARD ING GRA
IPC: G08B13/24
Filed: 1976-04-03
Abstract: The method is designed in particular for the delection of goods (3) stolen from counters in a store. The method uses two alternating magnetic fields which are used to sweep the surveillance zone (2). These fields act on marking elements (4) attached to the stolen goods which produce and radiate at least a frequency different to that of the alternating field frequencies. In order to counteract mutual influence and to suppress formation of harmonic frequencies or modulation attributable to simple coupling, the supply to the magnetic field generators is effected by an applied current. Whilst because of the non linearity of the marking element, an harmonic signal is produced which represents at least twice or a multiple of the base or excitation frequency.
