摘要:
Vulcanizable rubber compositions are disclosed which contain partial polycarboxylic acid esters or their salts. Vulcanizates obtained from the compositions are readily processible and are found to have reduced compression set and high tension values, in particular after ageing by heat.
摘要:
A process for the production of squaric acid by halogenation either of pure 3-acetoxy-2-cyclobuten-1-one or of a distillation residue of diketene production containing 3-acetoxy-2-cyclobuten-1-one to a cyclobutenone of formula: ##STR1## and then hydrolysis of these cyclobutenones to squaric acid. The halogenated cyclobutenones are intermediate products in the process.
摘要:
The invention relates to a process for coating moldings via co-extrusion with a UV-absorber-containing layer containing special dimeric UV absorbers and to the moldings coated with a corresponding layer.
摘要:
An improved aqueous coating agent for providing a decorative and protective coating for wood or wood products contains as a binder polyacrylate resins having chemically incorporated therein air-drying, unsaturated fatty acid moieties and quaternary ammonium moieties, and said agent is prepared by reactingA) excess polyacrylates containing epoxide groups and having an epoxide group equivalent weight of 200 to 1,300 withB) drying fatty acids, in an addition reaction with ester formation,C) reacting at least some of the remaining epoxide groups in the A)-B) reaction product with monoamine ammonium salts which contain an N-H bond in an addition reaction, anddissolving the reaction product obtained from step C) and containing quaternary ammonium groups in water.
摘要:
A filter device, in particular for fluids contaminated with water admixtures, such as diesel oil, has a filter housing (1) holding at least one filter element (9). The filter medium of the filter element separates an untreated side (13) from a treated side (19) during the filtration process in the filter housing (1). A water collecting unit (5) is provided and holds separated water on the untreated side. Water separated on the untreated side (13) also reaches the collecting unit (5). Mutually separated collecting chambers (61, 67) are present in the collecting unit (5) for the water discharged at the treated side (19) and at the untreated side (13).
摘要:
The present invention relates to a system and methods generally aimed at surgery. More particularly, the present invention is directed at a system and related methods for performing surgical procedures and assessments involving the use of neurophysiology.
摘要:
The invention relates to an apparatus for measuring blood oxygen saturation, comprising a housing (1), a sensor (2), a connecting cable (3) and a plug (4), wherein the housing (1) has a cavity (5) for accepting a patient's tissue which is supplied with blood; the sensor (2) which is arranged on the housing and has at least one light source (21) for the emission of light which passes through the tissue which is supplied with blood and a detector (22) for receiving the light passing through the tissue which is supplied with blood; and the apparatus can be connected to an evaluation unit via the plug (4).
摘要:
Example methods, apparatus and articles of manufacture to respond to signaling protocol failures in traffic engineering (TE) tunnels are disclosed. A disclosed example apparatus includes a database to store a tunnel state for a first TE tunnel, a signaling engine to detect whether a signaling protocol failure associated with the first TE tunnel occurred, and to set the tunnel state to a first logic state when the signaling protocol failure is detected, and a label switching engine to route the data through a multiprotocol label switching (MPLS) based network via a second TE tunnel when the tunnel state is the first logic state, and to route the data through the MPLS-based network via the first TE tunnel when the tunnel state is a second logic state.
