Abstract: A  polychromic  image  is   reproduced  and transferred onto a substrate by (a) providing a single positive  electrolytically  inert  electrode  having  a continuous passivated surface moving at substantially constant  speed  along  a  predetermined  path,   the passivated surface defining a positive electrode active surface;  (b) forming on the positive electrode active surface  a plurality of  dots  of  colored,  coagulated colloid  representative  of  a  desired  image,   by electrocoagulation  of  an  electrolytically  coagulable colloid present in an electrocoagulation printing ink comprising  a  liquid  colloidal  dispersion  containing said electrolytically coagulable colloid, a dispersing medium, a soluble electrolyte and a coloring agent; and (c) bringing an endless non-extendable belt moving at substantially the same speed as the positive electrode and having on one  side thereof a colloid retaining surface   adapted   to   releasably   retain   dots   of electrocoagulated  colloid,   into  contact  with  the positive electrode active surface to cause transfer of the  dots  of  colored,  coagulated  colloid  from  the positive  electrode  active  surface onto  the  colloid retaining surface of the belt and to thereby imprint the colloid retaining surface with the image. Steps (b) and  (c)  are  repeated  several  times  to  define  a corresponding number of printing  stages  arranged at predetermined locations along the path and each using a coloring  agent  of  different  color,  and  to  thereby produce   several   differently   colored   images   of coagulated colloid which are transferred at respective transfer positions onto the colloid retaining surface of the belt in superimposed relation to provide the desired polychromic image. A substrate is then brought into contact with the porous surface of the belt to cause  transfer  of  the  polychromic  image from  the colloid retaining surface onto the substrate and to thereby  imprint  the  substrate  with  the  polychromic image.

IPC: H02J3/14
Filed: 1996-05-17
Granted: 2005-04-19
Abstract: An apparatus for and method of evenly distributing an electrical load (BRANCH  CIRCUIT 1-5) across a three-phase power distribution network. The current in each incoming phase and in each branch circuit is measured by a plurality of current sensors (16-20 and 42-50). The output of the current sensors (16-20 and 42-50) are monitored by a processor (12). Associated with each branch circuit (BRANCH CIRCUIT 1-5) is a multi-pole switch (22-30) and a conventional circuit breaker (14).  Each switch (22-30) is able to connect its corresponding branch circuit (BRANCH CIRCUIT 1-5) to any incoming phase or to disconnect the branch circuit (BRANCH CIRCUIT 1-5) from all three phases. The processor (12) periodically monitors the current flowing through each incoming phase and based on branch circuit load conditions, reprograms the switches (22-30) to keep the branch circuit loads (BRANCH  CIRCUIT 1-5) evenly distributed across all three incoming phases. In another embodiment, a summing circuit (52) combines the current capacities of all three incoming phases into a single summed output. This output is subsequently rectified (54) and used to generate (56) a single phase AC voltage which feeds all branch circuits (BRANCH CIRCUIT 1-5) in the system.
