摘要:
Computer-based editing methods and systems for defining and generating transitions between video clips in a video presentation. Transition regions are defined at one or both ends of a video clip such that the transition region remains defined on the first video clip until the transition region is edited or deleted by a user. Making the transition region a property of the clip upon which the transition region is defined, and retaining that property while the clip is manipulated within a timeline of a video editing system reduces ambiguity as to how transitions are to be treated in the editing process. It also helps reduce loss of original video material associated with transition regions during the editing process.

A minimally invasive system and method for vertebral body augmentation includes an expandable containment device, a chassis including an interior cavity for at least partially enclosing the expandable containment device, a first guidewire, a working cannula, a second guidewire having at least a partially flexible distal end portion and a sleeve for introducing bone filler material through a cannulated passageway of the sleeve and into an interior cavity of the containment device. The containment device preferably includes a plurality of pores for directing the outflow of bone filler material anteriorly within the vertebral body. The containment device and chassis are left interior to the vertebral body subsequent to height restoration and augmentation of the vertebral body.
摘要:
The present invention is directed to a porous or permeable containment device for implanting into the interior volume of a targeted vertebral body for use in restoring the anatomy of the targeted vertebral body. The containment device is expandable from an insertion configuration to an expanded configuration via, for example, a bone filler material. The containment device preferably permits the bone filler material to flow out of the containment device via, for example, one or more pores, one or more flow-directing tentacles, etc. so that the bone filler material may interdigitates with the surrounding bone tissue. The containment device is preferably configured to have a pre-determined, ‘dog-bone’ shape, when in the expanded configuration. The containment device preferably also includes one or more knobs or ribs to facilitate anchoring of the containment device to the surrounding bone tissue, one or more air or fluid evacuation pores to permit air or fluid from escaping from the interior volume of the containment device and/or one or more radiopacity rings or markers to enable a surgeon to locate and/or position the containment device under X-ray imaging.

The present invention deals with the proteolytic enzyme thermolysin which tends to be unstable in aqueous solution. The invention provides methods and compositions to enhance the stability of dissolved thermolysin in aqueous solution. Thermolysin, crude thermolysin or a lyophilisate containing thermolysin and one or more salts, is contacted with an aqueous buffer with a low salt concentration and a first solution is formed. Subsequently, a further salt in solid form is added and dissociated, thereby forming a second solution comprising thermolysin in a stabilized form.
摘要:
A device for separating sheets of a recording medium has a feed head (22) that, together with feed rollers (58), lies on the top sheet of a horizontally arranged stack of the recording medium. The feed rollers (58) push the top sheet against a rising incline, so that its leading edge is lifted up and separated from the stack. The feed head (22) is arranged on an arm (18) that is designed to swivel freely on a swiveling plane that is parallel to the plane of the incline. In the feed head (22), the feed rollers (58) can move away from the incline parallel to the plane of the stack against the spring force.

The present invention provides a continuous process for recovering acetone from a waste stream from an acetone purification stage. The waste stream contains mesityl oxide and optionally acetone. The process for recovering acetone includes separating the waste stream in a separating device at least in one stream containing mesityl oxide and optionally a further stream containing acetone, then concentrating mesityl oxide in the mesityl oxide containing stream, and finally recycling the concentrated mesityl oxide stream to the separating device and bringing it into contact with a basic or acidic aqueous medium or with an acidic catalyst in the presence of water whereby mesityl oxide is at least partially hydrolyzed to acetone.

The present invention relates to a process for preparing sulfur-containing compounds of the general formula I in which Q, R1 and R2 are each independently defined as follows: Q: —S— or —S—S—, R1: hydrogen or saturated or unsaturated, linear or branched C1-C30-alkyl radical, R2: hydrogen or saturated or unsaturated, linear or branched C1-C30-alkyl radical, where R1 and R2 are not simultaneously hydrogen, by reacting a mixed gas stream comprising hydrogen sulfide, with or without oxygen, with linear or branched C1-C30-olefins, which comprises carrying out the reaction in the presence of water and carbon dioxide at a pressure of from 2 to 325 bar.
摘要:
The present invention relates to a process for preparing alkyl thiols by adding hydrogen sulfide to double bonds of C6-C20 olefins at a temperature of from 20 to 150° C. and a pressure of from 1 to 40 bar, wherein the reaction is carried out in the presence of at least one organic, liquid acid, and to the use of organic, liquid acids as a catalyst for increasing the selectivity and/or reaction rate in the addition of hydrogen sulfide to double bonds of C6-C20 olefins to prepare alkyl thiols.
