Patent BE-904561-A (BE)
Title: Portable EM vibrator for pollinating plants - has battery powered needle vibrated to dislodge polled
IPC: A01H1/02
Filed: 1986-04-08
Abstract: A 3mm dia. operating needle is introduced into the bloom and a motor inside the vibrator moves it from side to side via an eccentric coupling. The needle dislodges pollen from the stamens which falls onto the carpels and fertilises the seeds. - The junction between the lower end of the stainless steel needle and the vibrating coupling is sealed by a flexible cap of plastics material. The d.c. supply from the rechargeable nickel cadium batteries is fed via an electronic speed control card and an on/off switch to the motor. The motor shaft is coupled to a shaft via a rubber shock absorber and the other end of the shaft has an eccentric pin which rotates the coupling into which the needle is inserted. (10pp Dwg.No.0/3)

Abstract: Title of the Invention AUTOMATIC DEVELOPMENT ELECTRODE       BIAS CONTROL SYSTEM                 Abstract of the Disclosure An automatic control system for the bias on a development electrode in which a plurality of ground-insulated, narrow floating electrodes are spaced along a line adjacent the entrance of a liquid developer applicator unit.  the floating electrodes relatively scan image areas of the surface of an organic photoconductor carried by a conductive support moving through the developer unit. Owing to conduction of a charge from the photoconductive surface through the developer liquid to the floating electrodes, they assume potentials each of which is a function of the average potential of the image area subtended by the floating electrode.  The potential of each floating electrode is sensed by a high input impedance measuring circuit which selects the potential of the low-est value, amplifies the selected potential and applies the amplified voltage to the biasing electrode or electrodes of the developer system.           A fully charged and unexposed area of the surface following the image area produces a reverse bias which cleans the biasing electrodes as the fully charged area passes through the developer system.

Abstract: ABSTRACT OF THE DISCLOSURE   Particulate radioactive wastes are packaged for storage until rad-ioactivity decays by fastening a tight mesh fabric bag in a barrel or other suitable storage container, filling the bag with a mixture of radioactive waste material and a non-radioactive liquid material, and then solidifying the non-radioactive liquid to encapsulate the radioactive waste.  The tight mesh weave of the fabric bag acts as a barrier to the particulate radioactive material but not to the liquid.  A portion of the liquid thus flows through the bag to form a protective layer between the bag and outer container wall.  The remain-der stay in the bag and mixes with the radioactive particulate.  Solidification of the non-radioactive liquid produces a monolithic solid having a protective layer of solidified non-radioactive material covering the entire surface area of an immobilized mass of radioactively contaminated particulate material.
