Patent DE-4103804-A1 (DE)
Inventor: NOE OSKAR DIPL ING
IPC: B21D1/05
Filed: 1991-02-08
Abstract: The invention relates to a straightening plant for metal strips with a stretch-bending apparatus. The stretch-bending apparatus is arranged between two drivers which replace otherwise customary sets of tensioning drums and produce the strip tension required for stretch-bend-straightening. Threading of the respective strip is thereby facilitated and the strip losses due to the absence of strip treatment which otherwise have to be accepted are furthermore considerably reduced.

Inventor: FELD MARCEL DR
IPC: C07C211/63
Filed: 1991-02-14
Abstract: Quat ammonium salts of opt C5-substd 2-thiobarbituric acid derivs of formula (I) and their tautomeric forms are new. R1 and R2 = H, aryl, alkyl or benzyl; R3-R6 = alkyl, phenyl or benzyl. (I) can be prepd by (a) reacting a quat ammonium halide of formula XNR3R4R5R6 (II) in soln or suspension in a solvent, pref in an alcoholic medium, with an alkali alcoholate; (b) removing the alkali halide formed; and (c) reacting the quat ammonium alcoholate formed with a 2-thiobarbituric acid of formula (III) or with one of its tautomeric forms, or reacting the quat ammonium alcoholate with thiourea and a malonic acid dialkylester of formula R00C-CR1R2-C00R (IV) (R=alkyl). USE/ADVANTAGE - (I) are intermediates in the prepn of thio-barbituric acid derivs (such as 2-(methylthio)-barbituric acid) which are themselves intermediates in the prepn of pharmaceuticals, insecticides and fungicides. (I) are better soluble in organic solvents than the corresp alkali salts, thus facilitating the use of organic rather than aq reaction media, leading to higher reaction rates or improved selectivity and avoiding the need to dispose of aq wastes.

Title: Closing down burning oil wells with min. danger to personnel - uses tunnelling and excavating technique to clamp and insert valve remote from oil well head
Inventor: SCHLUTTENHOFER LUDWIG
IPC: E21B29/08
Filed: 1991-03-28
Abstract: A process and appts. for shutting down burning oil wells, where oil is under pressure. The process claims to reduce the danger to personnel. The novelty is the technique of tunnelling beneath the oil pipe, excavating a subterranean gallery around the pipe, and closing the pipe at that point. The oil pipe may be simply closed by means of hydraulic clamps pressing the walls of the pipe together. To ensure complete safety if the pipe material is too brittle, a collar with oil pressure seals is clamped around the pipe. An extension piece securely attached to the collar and sealed, carries a borer to cut hole in the wall of the pipe. Once the pipe is cut, the borer is withdrawn, allowing a slide valve to be inserted in the oil pipe, thus shutting off the oil flow. Alternatively the face of the cutter can be backed with a round block, the dia. of the oil pipe, which is pressed into the pipe after the pipe is completely bored through and thereby blocking off the oil flow. ADVANTAGE - Allows burning oil feed pipes, partic. oil well fires to be brought under control in complete safety.

Patent DE-4119095-A1 (DE)
Inventor: RITTER JOACHIM DIPL ING
IPC: F16D15/00
Filed: 1991-06-10
Abstract: The invention relates to a switchable freewheel with two mutually concentric cage rings and locking elements fitted in recesses thereof, whereby the cage rings are movable in relation to each other to switch the freewheel. So that such a freewheel may also essentially be operated in two opposite directions and thus provide simple switchover facilities in one direction only, the relative movement of the two cage rings acting to switch the freewheel is an axial movement which can be converted into a rotary movement for any further embodiments of the freewheel.

Title: Sewing machine - has adjustment mechanism to set dead positions of needle shaft movement
Inventor: NAKANO MOTONARI
IPC: D05B55/14
Filed: 1992-08-28
Abstract: Drive mechanism for the needle shaft includes a system (44, 62, 72) to vary at least the upper or lower dead position of the needle shaft, in its vertical reciprocating movement.
