摘要:
A gripper for capturing and transporting a food product. In one implementation the gripper has first and second arms having first end portions that cooperate with each other to capture the food product. In a first pivot position the first end portion of the first arm is positioned to cooperate with the first end portion of the second arm to capture the food product, whereas in a second pivot position the first end portion of the first arm is positioned not to cooperate with the first end portion of the second arm. The gripper has an expandable fluid chamber that in an expanded state acts on a portion of the first arm to cause the first arm to assume the first pivot position.
摘要:
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.

A system and method are disclosed for reliable communications in a packet network. A system that incorporates teachings of the present disclosure may include, for example, a network management system (NMS) having a controller programmed to establish between first and second customer edge (CE) routers in a full mesh packet network first and second logical data tunnels conforming to an isolation protocol, synchronize packet data in the first and second logical data tunnels, enable packet data exchanges between the first and second CE routers over the first logical data tunnel, direct the first and second CE routers to duplicate the packet data exchanged between them over the second logical data tunnel, and direct the first and second CE routers to synchronously switch to the second logical data tunnel upon detecting a fault in the first logical data tunnel.

To improve energy efficiency of prior art processes while preserving the standards of quality and total yield of desired end products, a process for the preparation of phenolic compounds is proposed. The process of the invention comprises working-up of the cleavage product mixtures by distillation, which comprises resolving the cleavage product mixture into at least three fractions in a single distillation step by feeding the cleavage product mixture to the side of a distillation column, removing a first fraction comprising the ketone at the top of the distillation column, removing a second fraction comprising the phenolic compound at the bottom of the distillation column, and removing a third fraction comprising unreacted the alkylaryl compound and the hydroxy ketone, and water, as side stream, whereby the side stream take-off is situated above the feed of cleavage product mixture to the distillation column, characterized by removing heat from the distillation column, whereby the heat take-off is situated above the side stream take-off of the third fraction, and a process for separating phenol from cleavage product mixtures, wherein the cleavage product mixture prior feeding into the distillation column, is preheated to a temperature of above 70° C. at standard pressure, preferably to a temperature of above 100° C., more preferably to a temperature between 110° C. and 180° C., most preferred to a temperature of about 140° C. to 146° C., and an apparatus suitable therefore.
