| 20110192323 | Process to disperse and / or grind and / or concentrate calcium carbonate in aqueous media using an aqueous solution containing zirconium compounds - It is an object of the present invention to provide a process of manufacturing calcium carbonate-containing slurries, wherein said calcium carbonate-containing slurries are prepared by adding one or more zirconium compounds, and possibly one or more further phosphate-free additives acting as dispersing and/or grinding aid agents. An other object of the invention lies in calcium carbonate-containing slurries thus obtained, and dry calcium carbonate mineral pigments resulting from the drying of such slurries. A further object of the invention is the use of such slurries and such dry mineral pigments in paper manufacturing, plastic coatings, as fillers for plastics or for aqueous paint compositions and the like. Papers, paints and plastics containing such slurries and such dry pigments are also an object of the present invention. | 08-11-2011 |

| 20100058719 | Conveying apparatus for envelopes and related methods - An apparatus for conveying envelopes traveling in a travel direction in a generally upright orientation. The apparatus includes a first pair of conveyor assemblies disposed opposite one another and configured to engage lateral edges of the envelopes, and configured to move the envelopes in the travel direction. The apparatus includes a second pair of conveyor assemblies disposed opposite one another and positioned downstream of the first pair of conveyor assemblies in the travel direction, with the second pair of conveyor assemblies being configured to move the envelopes in the travel direction independently of the first pair of conveyor assemblies. | 03-11-2010 |

| 20100059335 | Transporting apparatus for web products and related methods - Apparatus is provided for transporting a paper or film discrete object in a machine direction. A top engaging portion contacts a first side of the object and a bottom engaging portion contacts a second side of the object opposite the first side and respectively cooperates with the top engaging portion to grip and move the object in the machine direction. At least one of the top engaging portion or the bottom engaging portion includes a plurality of deflectable elements for engaging the object. | 03-11-2010 |
| 20100059920 | Envelope conveying and positioning apparatus and related methods - An apparatus for processing envelopes. A support plates and a pressure sensing lever support a stack of envelopes in a generally upright orientation. The pressure sensing lever pivots in accordance with pressure exerted by the stack of envelopes. A feeding apparatus is operatively coupled to a sensor such that pivotal movement of the pressure sensing lever is detected by the sensor and the feeding apparatus changes the pressure exerted against the stack of envelopes. | 03-11-2010 |

| 20100059918 | Inserting apparatus for discrete objects into envelopes and related methods - An apparatus for inserting a paper or film object or a stack of such objects into an envelope. A feeding apparatus moves the object toward an insertion station and a vacuum drum has a surface adapted to engage and move the envelope toward the insertion station. A ramp element is coupled to the vacuum drum and is adapted to support a leading portion of the envelope as the envelope moves With the vacuum drum. | 03-11-2010 |
| 20100059919 | Transporting apparatus for discrete sheets into envelopes and related methods - An apparatus transports a discrete paper or film object in a machine direction for insertion into an envelope. A guide assembly of the apparatus includes opposed first and second channels facing one another for guiding the object in the machine direction, with the channels extending upwardly to thereby define an uphill path of travel for the object. A drive apparatus includes engaging elements for moving the object along the first and second channels. At least one support element holds the object against the guide assembly. | 03-11-2010 |
