The invention concerns a fluidically operable manipulator made up of several manipulator segments stacked along an extension curve, each comprising at least one connecting plate and at least two fluidically separated fluid chambers spaced apart on the connecting plate at right-angles to the extension curve, wherein each of the fluid chambers has at least one elastically deformable wall section which is designed to make possible, on pressurization of the respective fluid chamber with a fluid, a change in volume of the fluid chamber for a linear movement substantially parallel to the extension curve, and wherein a main extension surface of the connecting plate is provided for an arrangement at least substantially at right-angles to the extension curve, wherein the two or more fluid chambers are made integral with the connecting plate or plates.

Disclosed is a method for manufacturing a multilayered duplex material article. The method comprises providing a first layer from a non-cast material and a second layer from a cast material wherein the second layer is made from a material with a lower melting point than the first layer. In one embodiment the first layer is a wrought alloy and the second layer is cast onto the first layer.

A motor vehicle with a sliding door has a safeguard with two mounting elements. One of the mounting elements is secured to the sliding door, while the other mounting element is arranged on a column bordering the sliding door. The mounting elements pass by each other given a sliding motion by the sliding door, and end up opposite each other during the motion of the sliding door, transversely to the sliding motion. As a result, the safeguard holds the sliding door against the column during a crash in which forces act perpendicularly on the sliding door.

A frame assembly has a surface bearing element which comprises at least one glass pane. A plastic profile frame (1, 2) encloses the end face of the surface bearing element. For strengthening purposes, the plastic profile frame (1, 2) has reinforcing components (7, 14, 19, 26, 35) of fibre-reinforced plastic. A receiving portion (3) is provided as an enclosing edge portion of the surface bearing element. The reinforcing components (7, 14, 19, 26, 35) of fibre-reinforced plastic are boundary walls of internal hollow spaces (9-11, 16-18, 21-23, 28-30, 37, 38) which, together with non-reinforced boundary walls, bound the internal hollow spaces. The profile frame (1, 2) is embodied as a coextrudate of the reinforcing components (7, 14, 19, 26, 35) and the non-reinforced boundary walls (4, 5, 6, 12, 13, 25, 31, 32, 33, 34). This results in a frame assembly which can be produced using mass production techniques with minimal use of fibre-reinforced plastic material.

The present invention relates to modified cytochrome P450 monooxygenases with an altered substrate profile, to nucleic acid sequences coding therefor, to expression constructs and vectors, to recombinant microorganisms which comprise these vectors, and to processes for the microbiological production of terminally or subterminally hydroxylated aliphatic carboxylic acids.
摘要:
The invention relates to novel cytochrome P450 monooxygenases comprising a modified substrate specificity, to nucleotide sequences which code therefor, to expression constructs and vectors containing these sequences, and to microorganisms transformed therewith. The invention also relates to methods for microbiologically oxidizing different organic substrates, such as methods for producing indigo and indirubin.
摘要:
A test device and a test method, the test device comprising a bus controller for the transmission and reception of bus messages, the bus controller having a message memory for offering transmission data for bus messages, the message memory having a memory capacity for a bus message sequence with bus messages to be transmitted within a single transmission cycle or a transmission cycle sequence. The test device includes an intermediate memory for the storage of transmission data for bus messages with a larger storage capacity than the message memory. The test device furthermore comprises a transmission preparing means for reading transmission data from the intermediate memory and for writing, in advance of reading of the bus controller, to the message memory of the bus controller so that the bus message sequence is expanded by additional bus messages which are transmitted by the bus controller within the transmission cycle or the transmission cycle sequence on the motor vehicle bus.
摘要:
The tray has an infusion field of infusion tab valves adjacent the inlet to dissipate the momentum of the liquid flowing across said infusion field. Each valve includes a vertically upstanding wall of a height to obstruct the flow of liquid and the valves are disposed in a staggered array. An adjacent bubbling area has openings for the passage of an ascending flow of vapor into contact with the liquid/vapor mixture flowing across the area. Each infusion tab valve may also have a push valve incorporated therein.

The tray valve for a tray column includes an opening in a tray for a vapor passage and a valve body that is made to match the tray opening. The valve body consists of a top plate and vertically downwardly directed guide limbs arranged at the edge of the plate. The guide limbs have barbs for the anchoring of the valve body in the opening. The material and shape of the valve body are selected so that upon insertion of the valve body into the tray opening the top plate deforms in an arched manner while the guide limbs and barbs without deformation pass through the opening in a snap-fit manner. Weakened portions, in the form of grooves, slits or bores, can be provided in the top plate to facilitate upward arching of the top plate. Any deformation at the inserted valve body can be reversed, with the exception of a slight residual deformation, by an application of force onto the top plate.
