The method makes accessible new substrates in the enzymatic production of L-glufosinate and its phosphoesters.

Abstract: On a contour welding machine with welding rollers), the workpiece is arranged on a holder that is freely rotatable during the welding operation. Its rotation by the driven welding rollers engaging the workpiece is compensated to a greater or lesser degree to suit the contour profile by shifting the position of the holder in relation to the welding rollers. This enables contours to be welded simply and inexpensively. With a driven check angle, a skip back to the starting point can be made in the case of open contours and/or friction rollers can be dispensed with.

Abstract: A gripper loom with at least one filling thread insertion device, including a perforated flexible insertion band, which carries a gripper head at one end and which is advanced into and again retracted from a shed by an alternatingly driven drive wheel. The drive wheel has teeth distributed across the circumference which engage into perforations of the insertion band. Furthermore, a guide member is assigned to the drive wheel near the gripper head so as to prevent the insertion band from lifting off the circumference of the drive wheel, and an end of the band facing away from the gripper head is fastened at a rotary guidance apparatus arranged with respect to the drive wheel so that the band end describes an at least approximate circular guide path during an entire reciprocating motion, the radius of the path being larger than the radius of the drive wheel.

Abstract: The conveyor apparatus is connecting a cutter, by means of which sheet metal blanks are produced in adjacent rows, to the magazine of a can welding apparatus which produces from the sheet metal blanks can bodies. A row of adjacently arranged depositing receptacles for receipt of at least one sheet metal blank each is located along the cutter on a frame. Two conveyor chains having dogs move along the depositing receptacles of which each presents a bottom surface which rises in the direction of transport such that the dogs push the sheet metal blanks from one to the next depositing receptacle and accordingly collect the sheet metal blanks out of all depositing receptacles such to form a pile at the end. Such pile is taken over at the end of the path of transport of the conveyer chains by a further conveyer means in form of elastically supported pawls.

Abstract: In order to produce can bodies having a noncircular cross-section, preferably a rectangular cross-section with rounded corners, flat planar blanks are initially deformed in a deforming station by a plurality of similar bending tools, each for producing one respective bend, whereby a respective different bend is made at the same time at the various blanks of the stepwise timed advancing blanks. The bending tool includes a shaping member held stationary at the inside and having a curved outer surface end, furthermore, a roller supported in a supporting body and which is subjected to the action of a spring pressing against the supporting body in order to bend the blank located between the shaping member and pressing roller upwardly during movement by a lifting rod pivotably mounted at the supporting body. This proceeds simultaneously in all bending tools provided for one respective bend by a movable part of the deforming apparatus operating as a press.

Abstract: A mechanical loom including a shooting device for shooting a shuttle into the shed from an initial position into a receiving position at a transfer device. The shuttle is connected through a flexible return element to a return member of a return device, so that the shuttle can be returned into the initial position and, simultaneously, a weft thread can be pulled into the shed. The return device includes a release device which releases the return element from the return member when the shuttle has reached the initial position. The mechanical loom is of simple construction and low weight. The weft thread is pulled into the shed in a careful manner, so that the weaving machine has a high efficiency.

Abstract: A method and a machine for weaving a ribbon-type fabric in which a first weft-yarn is introduced into the warp shed by a first insertion organ and an auxiliary yarn is inserted into the warp shed by a second insertion organ at the side of the yarn shed where a knitting needle is positioned. A second weft yarn is also introduced into the warp shed at the side of the knitting needle. The needle catches the auxiliary yarn and the insertion organs are moved over the warp yarn shed so that the auxiliary-yarn loops formed run parallel to the weft-yarn loops over at least a part of the width of the warp shed.

Abstract: In the method for the production of a fabric, particularly tape fabric, two weft thread loops formed from different weft threads are laid into a shed formed of warp threads and bound off without use of an auxiliary thread. This is made possible thereby, that at least one weft thread is guided into the shed through a tooth gap of the reed.

Abstract: Method and device on a loom for the manufacture of a woven fabric, wherein weft thread loops are formed by a weft thread in a shed formed of warp threads. Through feeding the weft thread in within the warp width and out to both sides over the outermost warp threads while forming loops, a woven fabric is obtained with like fabric edges which can no longer be distinguished optically.

Abstract: A welder for welding side seams of tubular bodies. The welder has a body feed in the form of a single conveyor which serves to receive bodies at regular intervals from a rounded unseamed tubular body supply and to move the bodies into a welding head nip with the bodies being initially widely spaced and then the gap between a body in the welding head and a trailing body being rapidly reduced so that the leading edge of a following body enters into the nip at the same moment as the trailing edge of a leading body begins to depart from the nip, with the adjacent edges of adjacent bodies being in substantially touching but positively spaced relation.

Abstract: A pusher needle wherein the oscillating movement in horizontal and vertical direction is replaced by an oscillating rotational movement affording an increase in the needle frequency, and thus, a production increase during the stitch formation. The oscillating rotational movement is caused by a curved construction of the pusher guide and the pusher portion displaceable therein.
