Title: Method for removing organic and inorganic residues in a soldering process
Inventor: TOLVGAARD BENGT ARNE
IPC: H05K3/34
Filed: 1989-03-15
Abstract: The invention relates to a method for removing organic and inorganic residual products prior to a soldering process. According to a known method, the steps of   a) flux treatment for removing oxides, residues of acid, and grease (fat),   b) heating,   c) soldering, and   d) washing of the object to the soldered, e.g. a printed circuit  take place. According to the proposed method, the washing is carried out immediately prior to the soldering process, which thus constitutes the last process step. Washing can be carried out with water in two stages, the areas to be soldered being coated, in the last washing stage, with a carrier/solvent for surface protection, in order to prevent oxidation prior to the soldering process. <IMAGE>

Title: Hood for pile to reduce damage by impact of pile driver - is made from steel plates mounted one above another
Inventor: SCHNELL HANS-GUENTHER
IPC: E02D13/10
Filed: 1990-03-20
Abstract: When piles are driven into the ground by a pile drum in order to construct foundations the head of the pile is covered with a hood in order to protect the head of the pile and to protect the surface of the pile driving hammer. These hoods are usually made of wood plastic hemp rope or steel cables. Such hoods are subject to rapid wear and have to be replaced at frequent intervals at great expense. The invention proposes to reduce this expense by using hood formed from steel plates mounted on above another. These steel plates reduce the severity of the impact of the hammer on the pile but have a much longer service life than that of the hoods at present in use. USE - Pile driving.
Patent DE-4011398-A1 (DE)
IPC: B67B3/20
Filed: 1990-04-09
Abstract: A slewing mechanism for screw closures, in particular of plastic, for containers has a drive and a torque-limiting device. It is characterized in that the torque-limiting device used is a control mechanism (19) which controls the energy supply to the drive (9) in function of the closing torque and/or in function of the angle of rotation of the closure (3) measured by an angle of rotation sensor (17). The control mechanism activates a switch device in function of the signal from a torque sensor (15) or an angle of rotation sensor (17). The signal is compared in a comparator (21) with predetermined torques or angles of rotation. The switch device can switch on, interrupt or reverse the energy supply to the motor (9). If the energy supply is reversed, the direction of rotation of the motor is reversed.
Patent DE-4013946-A1 (DE)
Inventor: GEIRHOS JOSEF
IPC: D02J1/00
Filed: 1990-04-30
Abstract: An entangled multifilament yarn made of high-modulus individual filaments, such as, for example, aramide, carbon or glass, and a method of making this yarn are described. Customary air entangling is virtually unusable in the case of high-modulus yarns, since, owing to their brittleness, they have a tendency to break, which leads in particular to a substantial decrease in the tenacity. The invention proposes to carry out the entangling at elevated temperature, either by preheating the yarn or by heating the entangling air. Surprisingly, it has been shown that this substantially avoids a lowering of the tenacity at relatively low entanglement spacings and in some cases even makes it possible to increase the tenacity. The multifilament yarn made by this process is distinguished in particular by a small number of breaks of the individual filaments. The invention is also applicable to so-called comingled yarns in which only a portion of the yarn consists of high-modulus filaments and the other portion of thermoplastic filaments.

Title: Deep drawing producing vane pump housing - uses reverse drawing which presses peripheral bead to give sharp edge at flange
Inventor: BRANDSTAEDTER MANFRED DIPL ING
IPC: F01C21/10
Filed: 1991-03-26
Abstract: The deep-drawing method produces a sheet-metal housing for a rotary pump, paticularly of the vane type. The housing is pot-shaped with a radial flange at the edge. After drawing to form the pot with flange, a reverse-drawing operation forms a peripheral bead (28) at the edge of the pot, protruding in the axial direction above the surface of the flange. The latter is then held down and the bead is secured round its outer edge. The bead is then pressed downwards towards the flange surface, causing its material to flow towards the pot edge and there form a sharp unradiused edge. ADVANTAGE - The flange face forms with the internal face of the pot a sharp right-angled edge, which is essential for a vane-pump housing.
