IPC: B41F31/30
Filed: 1990-03-28
Abstract: ABSTRACT OF THE DISCLOSURE.          To permit matching of the surface characteristics of an anilox roller (7) or of an ink application roller (6), or of rollers in a damper system (8), to printing requirements, the rollers are formed of a roller body over which a jacket or sleeve (34) is placed having the desired surface characteristics, for example a raster or screen pattern, cells or the like, for receiving and applying ink and/or damping fluid, respectively.  The sleeve (34) is selectively replaceable and can be positioned over the roller.  To permit such positioning without removing the roller from the printing machine, the printing machine is formed with an opening (31, 30) in one (1) of the side walls of sufficient size to permit passage of the sleeve therethrough, removal of a sleeve from the roller, and replacement by another sleeve on the roller.          An auxiliary support system (35-43)  supports the roller, in cantilever position, when the bearing from the first side wall (1) is removed, the auxiliary support system, preferably, including an eccentric shaft with a V-groove formed centrally therein, which can be brought into and out of engagement with an extension of one of the stub shafts of the roller.

Title: Apparatus for the measurement of drive torques
Inventor: MERCAT JEAN-PIERRE
IPC: G01L5/00
Filed: 1990-04-11
Abstract: ABSTRACT OF THE DISCLOSURE    A torque measurement system for a wheel, such as a bicycle or exer-cise bicycle wheel is disclosed where in the  torque induced relative rotation between a hub and driven axle is multiplied within the hub by a lever mechanism by a factor of up to about 10 before being read by sensors incorporated  into  the hub.   By  this means  a relatively  small  torque induced movement comprising a relative rotation between the driven axle and the hub of only about 1 degree is linearly converted to a figure many times larger which can be conveniently read.

Title: Photoelectrochemical cells using metal oxide ceramic membranes
Inventor: O'REGAN BRIAN
IPC: H01M14/00
Filed: 1990-06-29
Abstract: PHOTOELECTROCHEMICAL CELLS USING METAL OXIDE                CERAMIC MEMBRANES                 Abstract of the Disclosure A photoelectrochemical cell is made from a pair of electrodes placed in an ionic salt solution.  The photoresponsive electrode is metal oxide semiconducting ceramic membrane.   The advantageous porosity, and thus increased surface area, of the membrane make a solar cell of this design more efficient due to the larger contact area between the metal and the ionic solution than crystalline electrodes.  Such titanium dioxide membranes are also transparent which allows for the stacking of electrodes of cells, including electrodes designed to absorb radiation at different wavelength to again increase overall efficiency of light absorption.  Dyes can be added to the membrane to archive absorption of light at desired bandwidths.  A dopant, such as  niobium, can be added to a titanium oxide membrane to increase conductivity without any accompanying loss of conductivity.

Filed: 1991-01-02
Abstract: A touch input device, suitable for use in detecting the presence of an opaque element within a display area bounded by light emitting elements and light detecting elements includes light emitter activating circuitry in which the light emitting elements are individually selectable.  Each light emitting element is contained within a matrix (70) and source drivers (60) and sink drivers (80) are effective to select a specific row and column address for each individual light emitter.          Current for the light emitters is provided by a voltage source which is chose for compatibility with the logic used in the touch input system.  A charge pump (50) operating sequentially with the selection light emitting elements is used to establish a voltage greater than the normal supply voltage to overcome the voltage drops of the source driver (60) and sink driver (80) and the activated light emitter to insure light emission greater than a minimum threshold.
