| 20120211182 | Safety Gate - A safety gate has a frame with spaced apart top and bottom assemblies and spaced apart side assemblies in a deployed configuration. The top and bottom assembly length is extendable and retractable between the opposed side assemblies. A flexible barrier is connected to the frame. A one-way jack mechanism can be carried on each of the top and bottom assemblies. The length of the assemblies can be extended without actuating the jack mechanisms to adjust the frame to nearly fit a space between two surfaces. The jack mechanisms, when actuated, incrementally further extend the top and bottom assemblies so the frame interferingly fits between the two surfaces under compression. The frame can be reconfigurable between a compact configuration and the deployed configuration. The side assemblies can include latches that lock the frame in the deployed configuration. | 2012-08-23 |
| 20120211183 | METHOD AND APPARATUS TO PRODUCE PULP USING PRE-HYDROLYSIS AND KRAFT COOKING - A pulp cooking system including: a cellulosic material feed system, a pre-hydrolysis reactor vessel and a Kraft cooking reactor vessel.

A wash zone is below the screens and allows wash liquid to flow through the feed material in a cross-current direction. The wash liquid and hydrolysate removed from the feed material is extracted through the screens. The feed material is maintained in a mildly acidic condition through the pre-hydrolysis reactor vessel until the material enters the Kraft cooking vessel where the feed material is treated with alkaline cooking liquors. | 2012-08-23 |
| 20120211184 | FRACTIONATION OF A WASTE LIQUOR STREAM FROM NANOCRYSTALLINE CELLULOSE PRODUCTION - During nanocrystalline cellulose (NCC) production, a considerable amount of sulphuric acid is used. After the separation of the NCC, the remaining solution contains sugars and residual sulphuric acid. The sugars are in the monomeric and oligomeric forms. To reduce the cost of NCC production and to produce other added-value products, the spent acid stream can be fractionated into sugar oligomers, sugar monomers, and acid. The acid can be recycled to the NCC manufacturing process after concentration. The sugar monomers and sugar oligomers can be used for the manufacturing of other valuable chemicals. Membrane nanofiltration can be used to achieve this objective. A polymeric membrane with a molecular weight cut-off in the range of 200 Dalton was employed. Using this approach, the majority of the acid was recovered in the permeate while the sugars were concentrated in a smaller stream. The sugar level in the separated acid/permeate stream was only about 3% of the original concentration. A second membrane filtration stage can be used to separate the monomeric from the oligomeric sugars. The two sugar streams can be employed in different applications to produce value-added products. | 2012-08-23 |
