Title: Method of multi-tone printing
Inventor: PATON ANTHONY DAVID
IPC: B41J2/205
Filed: 1990-10-09
Granted: 2004-02-24
Abstract: A method of multi-tone printing employs a drop-on-demand printing apparatus for depositing ink droplets on printing element areas of a medium which is movable relatively to said apparatus. The droplets are deposited from an array of channels on a medium which is movable relatively to the channels. The channels length and nozzle location and dimensions afford each channel with a high longitudinal resonant frequency and electrically actuable means supply energy pulses to selected channels at or near the resonant frequency of the channels to deposit from each selected channel in the corresponding printing element area of the medium a number of drops equal to the number of pulses applied thereto, the number of pulses applied being dependent on the tone of printing required. Single channel and colour versions of the invention are also disclosed.

Title: Roll for use in calenders and like machines
Inventor: WENZEL REINHARD
IPC: F16C13/00
Filed: 1992-03-05
Granted: 1995-11-21
Abstract: A controlled deflection roll for use in calenders and like machines has a non-rotatable carrier for a hollow cylindrical shell the end portions of which are rotatable on bearings and the central portion of which surrounds hydraulically operated shell deforming elements.  A first hydraulic circuit is provided to supply heated oil to the deforming elements, and a second hydraulic circuit serves to feed lubricant to the bearings.  The two circuits are separated from each other by thermal barriers which are installed between the shell and the carrier intermediate the deforming elements and the bearings.  Valves and/or flow restrictors are provided in the second circuit to vary the rate of feed of lubricant to and/or the flow of lubricant from the bearings.  This renders it possible to establish a desired temperature profile along the full length of the peripheral surface of the shell.

Title: Multi-level sulfide content pulping
Inventor: RYHAM ROLF
IPC: D21C3/02
Filed: 1992-05-22
Granted: 2002-11-05
Abstract: Paper pulp (e.g. kraft pulp or sulfite pulp) is produced utilizing at least two different supplies of cooking liquor (e. g. white liquor), having different percentages of lignin reaction enhancing or carbohydrate degradation slowing chemicals (e.g. one having low sulfide content, and the other high sulfide content). The high sulfide content supply is typically used to impregnate the pulp, while the second supply is used in other cooking stages (whether co-current or countercurrent). At least 60% of the sulfide of the cooking chemicals may be prodded in the first supply. Some of the sulfide in the first supply is desirably provided in the form of polysulfide or elemental sulfur. When about 2% polysulfide on wood is utilized yield is significantly increased. Utilizing multiple chemical (e. g. sulfide) content supplies results in an optimum viscosity/kappa ratio and/or pulp strength properties for the pulp produced.

Title: Zero loss waveguide coupler
Inventor: FINK DAVID
IPC: H01S3/139
Filed: 1993-04-19
Granted: 1998-07-14
Abstract: A waveguide coupler comprises a curved end reflector mirror that images a waveguide exit back into the waveguide with an essentially exact reproduction of the waveguide output intensity distribution.  The coupler also comprises a lens disposed near the waveguide exit at a point between the exit and the mirror, the lens providing a phase compensation to the beam passing therethrough such that the phase of the beam returned to the waveguide matches that of the exiting beam.  Thus, coupling losses due to clipping of the returned beam at the exit/entrance to the waveguide bore and coupling losses due to a mismatch of the returning field phase to that of the waveguide mode are made essentially zero. Other embodiments of the coupler are presented wherein the phase compensating lens is positioned at locations other than adjacent to the waveguide exit, or wherein no inversion of the imaged field field distribution occurs, or wherein the beam is not caused to be focused at the center of a lens, or wherein one waveguide is coupled to another waveguide having a similar sized or a dissimilar sized bore.
