| 20100147696 | COPPER-TIN ELECTROLYTE AND METHOD FOR DEPOSITING BRONZE LAYERS - Consumer goods and industrial articles are electro-plated with bronze layers for decorative reasons and to protect them against corrosion. The electrolytes used hitherto for producing decorative bronze layers are either cyanide-containing or, as in the case of baths based on organosulphonic acids, highly corrosive or have, as in the case of cyanide-free baths based on diphosphoric acid, unsatisfactory long-term stabilities. Electrolytes which are used for applying solderable bronze layers in the electronics industry usually contain toxic or very toxic thio compounds. The present invention provides a non-toxic electrolyte which displays long-term stability for the electrolytic deposition of decorative bronze layers and a corresponding process for the application of such decorative bronze layers to consumer goods and industrial articles. | 06-17-2010 |
| 20110060154 | PROCESS FOR PREPARING COMPLEXES OF PALLADIUM (HYDROGEN)CARBONATE WITH AMINE LIGANDS - The present invention relates to a process for preparing palladium complexes. In particular, the present invention relates to a process in which ammoniacal complexes of palladium (hydrogen)carbonate are converted into complexes with oligoamine ligands. | 03-10-2011 |
| 20110089043 | MODIFIED COPPER-TIN ELECTROLYTE AND PROCESS FOR THE DEPOSITION OF BRONZE LAYERS - The invention relates to a modified copper-tin electrolyte which is free of toxic constituents such as cyanides or thio compounds. The invention further relates to a process for the deposition of decorative bronze layers on consumer goods and industrial articles using the electrolyte of the invention. The electrolyte comprises an additive formed from epichlorohydrin and hexamethylenetetramine and contains carbonate or hydrogencarbonate ions. | 04-21-2011 |

| 20110107205 | METHOD AND APPARATUS FOR FACILITATING DOCUMENT SANITIZATION - One embodiment provides a system for facilitating sanitizing a modified version of a document relative to one or more sensitive topics. During operation, the system determines a privacy risk for a term in the modified version relative to the sensitive topics, wherein the privacy risk measures the extent to which the sensitive topic(s) can be inferred based on the term. Next, the system determines an information utility and privacy loss or gain for the modified version, where the information utility reflects the extent to which the modified version has changed and the privacy loss or gain reflects the extent to which the modified version is reduced in sensitivity. | 05-05-2011 |

| 20090158727 | HYDRAULIC SYSTEM - A hydraulic system for an agricultural vehicle is proposed. The hydraulic system comprises a main hydraulic circuit, which is fed with hydraulic fluid by a main hydraulic pump, a variable displacement charge pump which supplies charge pressure to the main hydraulic pump, and a lubricating hydraulic circuits. In order to keep efficiency losses on the vehicle to a minimum, particularly at high engine speeds, part of the hydraulic fluid delivered by the charge pump can be diverted to the lubricating hydraulic circuit. | 06-25-2009 |
