Patent DE-4326970-A1 (DE)
Title: Device for thermode cleaning in bow soldering systems
Inventor: SCHWEIZER MATTHIAS
IPC: B23K3/08
Filed: 1993-08-11
Abstract: The invention relates to a device and a method for thermode cleaning in bow soldering systems. The thermode bows are covered by flux and other contaminants after the soldering process. These contaminants become encrusted and affect the soldering and placing accuracy in the bow soldering of fine- and finest-pitch components onto the printed circuit board. These contaminants were mainly removed hitherto by mechanical cleaning methods. The non-uniform removal of the ceramic on the thermodes results in unevenness, which has an adverse effect on the soldering operation. In addition, there is also the risk of damage to or fracture of the ceramic bows. To avoid these disadvantages, a device is used according to the invention for cleaning thermodes in bow soldering systems, which device contains two rotating round brushes (3) in a tight housing containing cleaning medium. The round brushes (3) are arranged at an angle of 90 DEG  to one another and are driven together. The thermode bows are moved across the round brushes (3) at an angle of 45 DEG  to the brush axes (6) and at an insertion depth of about 1 mm across the bottom edge of the soldering bow. Damage to or fracture of the thermodes as well as the development of unevenness at the end face of the thermodes by the cleaning operation are thereby avoided. <IMAGE>

Inventor: COBAN HASAN
IPC: B62D1/19
Filed: 1993-11-20
Abstract: The steering column comprises a tube in which the shaft with steering-wheel turns. A plastics safety component engages in a recess in the column, and shears off under a force acting in the tube lengthwise direction. The component is formed by a protrusion (14) from a guide strip (11). The tube can be arranged to slide in a mounting on the car bodywork when shearing takes place. The strip (11) which is of plastic can be fitted between the mounting (8) and a guide, being prevented from sliding. The protrusion on it fits in a recess (15) in the mounting or guide (9), while these engage together via a dovetail-section guide.

Title: Fan generating fresh air used in exhaust of IC engine
Inventor: MUSCHELKNAUTZ CLAUDIUS DIPL IN
IPC: F01N3/22
Filed: 1994-01-26
Abstract: The unit that uses a fan to generate a flow of fresh air, is connected on its outlet side to the exhaust of an IC engine via a non-return valve (56). Between this valve and the junction with the exhaust pipe is the by-pass valve (94), whose piston (80) is spring loaded (102) towards the closed position. The valve is opened by the air pressure built up by the fan though a by-pass pipe (100), the pressure working on a diaphragm (72). This diaphragm divides the control chamber into a pressure chamber (74) and a spring chamber (76). The by-pass pipe is joined to the fan outlet before the non-return valve. There is an electric motor on the fan shaft.

The drawing shows a sawing table (cutting angles 45 DEG -90 DEG -45 DEG ) in a top view. Nos 1 + 2 show the guide rail in 90 DEG  and 45 DEG  position. Nos 3 + 4 designate the guide points required for the automatic cut-length adaptation. No. 3 acts in the direction of the arrow over the entire adjustment region and is connected rotatably to the guide rail. No. 4 acts in the direction of the arrow and serves for length compensation in the case of cutting angle adjustment and is likewise connected rotatably to the guide rail. No. 5 indicates the maximum workpiece width. No. 6 shows the support surface for the workpiece. No. 7 shows the lowered support surface, the actual workpiece support is constantly concealed by the guide rail. <IMAGE>

Title: Fluid actuated rotary drive with housing chamber
Inventor: STOLL KURT DR
IPC: F16K31/163
Filed: 1994-08-05
Abstract: A piston is located in a housing (2) chamber (3) of the rotary drive (1) which is non-rotatably coupled to a driven shaft (15) brought out from the housing. The outer periphery (27) of the piston contains several helical grooves (28,28'), extending both axially and in the peripheral direction. Into each groove fits a guide member (36,36') fixed on the housing. When the piston is axially displaced by applied pressure, it is forced into a rotary movement, which can be tapped at the driven shaft. The grooves are offset w.r.t. the piston peripheral direction, e.g. by 180 deg., as are the guide members.

Afin de permettre le verrouillage en rotation de l'outil (7), l'arbre intermédiaire (17) peut également être engrené, avec sa denture longitudinale (20), dans la denture (21) solidaire du carter. Toutes ces opérations s'effectuent au moyen d'un seul levier qui agit sur la partie en saillie (24). Le marteau perforateur convient à toutes les opérations de forage, de percussion et de burinage dans les secteurs privés et industriels.
