Patent DE-4003558-A1 (DE)
Inventor: KERN JOSEF
IPC: H01H50/28
Filed: 1990-02-06
Abstract: The relay disclosed has a leaf spring (9) which acts as a contact spring and armature-reset spring and which has two arms disposed approximately at right angles to each other. The end of the first arm is suspended from a pin (6c) on the return pole piece (6) so that it can turn freely about the point of suspension. In addition, the cross-section of this first arm is reduced so that it is mainly loaded in tension, the armature reset force being provided substantially by the second arm (9b) of the spring. By means of a support element located between the return pole piece (6) and the first arm (9a) of the spring, the latter is biased slightly outwards, however, so that it exerts a small directive force on the armature (7) in order to draw the armature in predetermined fashion into its bearing. Owing to the difference in cross-section, however, this force has virtually no effect on armature resetting.

Title: Suction system for removing separate layers of liq. - such as creamy emulsion of used coolant-lubricant from tank
Inventor: KOCZY BERNHARD DIPL ING
IPC: B01D17/02
Filed: 1990-03-09
Abstract: This is an arrangement for the removal by suction of a stratified liq. such as a partly creamed-up emulsion, esp. of used coolant/lubricant, from a tank. First suction intake is kept in one layer of the fluid by a float, and, in another layer, a second suction intake, which can be rigidly attached to the tank, is connected by pipes to the first intake and to a suction connection (7). Several variants include means of adjustment for the arrangement. The example shown is a tank (1) contg. used coolant/lubricant in two layers; a water/oil emulsion (5) and large amts. of creamed-up foreign oil (3). Adjustable float (2) keeps the first suction intake (4) within the oil phase (3). The valve (10) is adjusted to suit the ratio between the quantities of the oil phase (3) and the heavier emulsion phase (5). Items shown are, second suction intake (6) with non-return valve; suction connection (7); and attachment fitting (12).

Title: Pneumatic false twist spinner - has separate clamping lines for each sliver at final pair of drawing rollers
Inventor: STAHLECKER FRITZ
IPC: D01H1/115
Filed: 1990-11-28
Abstract: The pneumatic false twist spinning appts., with a common drawing unit for two slivers running next to each other, has a roller structure in the final pair of the drawing unit where the lower roller and/or the pressure roller each form separate clamping lines, for each sliver, through a centre roller section of reduced dia. A suction roller is after the final pair of rollers, in the direction of sliver travel, with a faster roller surface speed than the transport speed of the slivers. A belt guide in the drafting zone, before the final pair of rollers, has belts to give a larger width than the total of the two roller clamping lines and the space between them. The two final clamping lines of the final pair of rollers each have an axial length smaller than the dia. of the lower roller, and pref. 0.9 times the lower roller dia., or 0.75 times of dia. The pressure roller of the final roller pair has a roller body with a profiled mantle to give a centre section of reduced dia., or it carries two mantles axially sepd. from each other. The lower roller also has a reduced dia. sectin between the two outer clamping lines. ADVANTAGE - The air flow behaviour at the final pair of rollers is symmetrical for each sliver, even though a single drawing unit acts on them both, with symmetrical air movement at the feed and delivery sides.

Patent DE-4133305-A1 (DE)
Inventor: ZSCHAECK MICHAEL DIPL ING
IPC: B23K26/08
Filed: 1991-10-08
Abstract: The apparatus according to the invention for guiding a laser beam avoids tilting the laser beam with regard to the exposed plane by the laser beam being displaced parallel to a perpendicular direction of incidence. A support roller with a spiral band on the circumferential surface serves as deflection element. The band has a reflecting surface. A laser beam running parallel to the circumferential surface strikes the reflecting surface and is reflected towards the exposed plane. The striking point shifts on the reflecting surface of the band through rotation of the support roller so that the laser beam is displaced in parallel. The reflecting surface can be of hollow-mirror-like and slanting design. <IMAGE>
