Filed: 1988-03-22
Abstract: Le détecteur de niveau de liquide de type optique décrit comprend un corps à transmissibilité optique (28) pourvu d'une partie terminale à extrémité tronconique (32). Lorsque la partie terminale est exposée à l'air, l'angle d'incidence (i) de la lumière en chacun des trois points de réflexion (b, c, d) est inférieur à l'angle critique (c) et la totalité de l'énergie lumineuse transmise à travers le corps est alors en substance réfléchie vers l'intérieur. Cependant, lorsque la partie terminale est exposée à un liquide, la lumière subit une réfraction et l'intensité de la lumière réfléchie est réduite. L'intensité de la lumière réfléchie est utilisée pour indiquer si le détecteur se trouve au-dessus ou au-dessous de la surface du liquide.

Abstract: PCT No. PCT/EP88/00966 Sec. 371 Date Oct. 31, 1989 Sec. 102(e) Date Oct. 31, 1989 PCT Filed Oct. 26, 1988 PCT Pub. No. WO89/06714 PCT Pub. Date Jul. 27, 1989.An aggregate of spherical fibers, particularly for use as filling material for blankets, such as quilts, pillows or the like comprises fibers and/or threads that are wrapped spherically and essentially form a fibrous ball. So that the properties of the aggregate of spherical fibers are better, particularly for use as filling material in blankets, such as quilts, pillows or the like, it is proposed that the fibrous balls contain a mixture of fibers, whereby one type of fiber has a higher modulus of elasticity compared to another type of fiber. The fibers with the higher modulus of elasticity can also taper over their length.

Abstract: In known constructions and, in particular, in the renovation of old buildings, the problem arises that in the region of the flashings of windows and doors,  the dew-point isotherm is not located in the window frame (7) but appears at the materials in the region of the interior, thereby resulting in a discontinuity in the curve of the dew-point isotherm. In order to avoid this disadvantage, the invention proposes that the curve of the dew-point isotherm of the room climate running through the heat-insulating zone (2) in the region of the static layer zone (1) or the monolithic wall passes without discontinuity or interruption into the window frame (7). <IMAGE>

Abstract: The hitherto known picking attachments for harvesters consist of a one-part rotor with drawing-in blades arranged fixedly on it. In the event of wear of the drawing-in blades, the entire rotor has to be exchanged. To reduce the maintenance outlay, it is proposed to arrange on the blades (3, 4, 5, 6) of the drawing-in rotor (2) wearing strips (10, 11, 12, 14) which can easily be exchanged, so that the entire drawing- in rotor (2) does not have to be replaced in the event of wear of the drawing-in elements. It is proposed, furthermore, that it be possible for the comminuting knives (8) also to be brought into a position out of engagement with the slits of the blades (3, 4, 5, 6), and finally that there be additional cutting knives (29) in order to ensure that the stalks are pulled through and comminuted, without a compression of the stalks being necessary. <IMAGE>

Abstract: The present invention involves a container (1) and cap which is generally childproof and may be rendered non-­childproof permanently. The invention involves a container (1) having a cylindrical neck (3) at the top and threads (5) molded about the exterior of the neck as well as an inner cap (7) and outer cap (21). The inner cap (7) has a top (9) and cylindrical side wall (11) with threads (13) molded on the inside of the side wall (11) so as to mate with the threads (5) of the container (1). The top (9) or side of the inner cap (7) has ratchet type segments (15) on its outside and the outer cap (21) has ratchet type segments (27, 29) on the inside of its top (23) or side (25). The outer cap (21) has a cylindrical side wall (25) and is usually freely rotatable about the inner cap (7) so as to be childproof. When in the childproof configuration as described, downward pressure is required by the user so as to engage the two ratchet type segments (15, 27, 29) and thereby engage the two caps (7, 21) to permit opening. Further, the outer cap (21) has an opening (37) in its side wall (25) at a level near the bottom of the side wall (11) of the inner cap (7) and also has integrally attached thereto a flexible connector (31) and stop (33). The flexible connector (31) and stop (33) are located so as to permit insertion of the stop (33) into the opening (37) so as to extend beyond the opening (37) and push up the inner cap (7) so as to permanently lock it into a position wherein the inner cap and outer cap ratchet type segments (15, 27, 29) are permanently engaged. This renders the cap permanently non-childproof.

Abstract: A method for measuring distance by means of a resolver and a synchro or for measuring angles or for continuous position detection is described, in which periodic squarewave signals U1, U2 are supplied to the input coils of a measuring device and an output signal U3 is generated at the output of the measuring device by induction in another coil. The pulse width of the squarewave signals at the input of the measuring device follows a digital value  beta , the pulse widths of the squarewave signals being widened or narrowed step by step by means of a digital value  beta  in accordance with a coarse resolution and the output signal U3 being calibrated for zero depending on the value  alpha corresponding to the mechanical position and depending on the digital value  beta  by correcting counters which have the digital value  beta , and the known digital value  beta  then corresponding to the mechanical position  alpha . In the measuring method described, a higher resolution is achieved by additional fine resolution in that, when the pulse width of the squarewave control signals is changed, the amplitude of the next pulse width of the squarewave control signals is first changed step by step in accordance with individual steps of an additional fine resolution.
