Title: Apparatus and method for improving density uniformity of a fluidized bed medium, and/or for improving material fluidized bed sorting.
Inventor: ZALTZMAN ARTHUR
IPC: B03B5/30
Filed: 1991-08-19
Abstract: An apparatus for providing a fluidized bed to effect the separation of a mixture of articles having at least a first density and a second density that is greater than the first density into separate groups. The apparatus includes an inclined trough which is supplied at an input end with either a fluidization medium, such as sand, or a mixture of articles from which a fluidized bed is formed by forcing gas upwardly through the bottom of the trough and through the fluidization medium or the mixture. In the case where a fluidization medium such as sand is used, the mixture of articles is introduced into the fluidized bed medium so as to be entrained therewith to effect separation as the articles travel in the direction of flow of the fluidized bed medium. Vertical oscillatory movement is imparted to the inclined trough to improve the separation and layering where the mixture of articles is fluidized, or to improve the density uniformity where a fluidization medium such as sand is fluidized as the bed.

Abstract: A process and apparatus for precipitating a silver halide emulsion is disclosed. The process is comprised of the steps of adding silver ions to a dispersing medium containing halide ions within a reaction vessel to initiate growth of silver halide grains within the dispersing medium, monitoring the temperature of the dispersing medium to establish the equilibrium solubility product constant of silver and halide ions within the dispersing medium; concurrently, using a reference electrode and a first indicator electrode, monitoring the halide ion activity within the dispersing medium; and adjusting the level of dissolved halide ion in the reaction vessel to maintain a stoichiometric excess of halide ions, based on the equilibrium solubility product constant. In the process the potential difference between a silver ion specific electrode in contact with the dispersing medium within the reaction vessel and at least one of the first indicator electrode and the reference electrode is concurrently monitored to allow the level of dissolved silver ion to be determined independently of the equilibrium solubility product constant, and the level of dissolved silver ion in the dispersing medium is adjusted based on the potential difference to maintain a selected profile of dissolved silver ion during silver halide grain growth. The apparatus contains the elements necessary for the practice of the process.

Abstract: In an inductive flowmeter, the magnetic field generator (11), which generates a magnetic field in the pipe (10), is connected via an electronic switch (13) to an ac voltage source. The switch (13) is controlled in such a way that in each case it becomes conductive only at a zero-point crossing of the ac voltage and subsequently remains conductive until the next subsequent zero-point crossing of the excitation current (i). The useful voltage picked off at the electrodes (16a,16b) is integrated in an integrator (19), by means of which the disturbing (noise) voltage coupled into the electrode loop by self-induction goes to zero. In order to exclude remanence influences, each current pulse which is used in the formation of the integral has a prepulse sent before it. <IMAGE>

Abstract: The invention relates to an electric motor having at least two salient stator poles, carrying a winding, and having at least one thermal protection switch (21) which is allocated to the field winding. A reliable heat-conducting connection of this thermal protection switch (21) to the winding overhang (19) of the field winding is achieved in that the thermal protection switch (21) is arranged such that it can be latched in a holder (23) by means of an insertion slot (29) which is open towards the winding overhang (19), and in that the holder (23) has a sprung element by means of which the contact surface (33) of the thermal protection switch (21) can be pressed against the turns of the winding overhang (19). This results in a reliable and simple heat-conductive connection between the thermal protection switch (21) and the winding. In addition, fluctuations of the winding head height are compensated for without additional measures. <IMAGE>
