Abstract: Le polymère modifié décrit comprend une composition polymère thermoplastique comportant un copolymère greffé entre (1) un polymère thermoplastique préformé et (2) une composition monomère, laquelle comprend (a) au moins un monomère polymérisable contenant un groupe polymérisable et au moins un groupe de modification de polymère fonctionnel et (b) au moins un comonomère contenant au moins deux groupes polymérisables, ledit copolymère étant essentiellement exempt de monomère non lié. On peut produire de tels polymères en les faisant réagir ensemble, dans un bain de fusion et en présence de radicaux libres, tout en appliquant une force de cisaillement sur le bain de fusion, sur le polymère thermoplastique préformé à modifier, sur le monomère polymérisable et sur le comonomère. On obtient ainsi le greffage dudit monomère sur le polymère préformé, ce qui ne laisse essentiellement aucun monomère non lié, la réaction étant poursuivie pendant un temps suffisant pour produire un copolymère greffé qui est thermoplastique et qui peut être mélangé à un polymère non modifié. Un générateur de radicaux libres peut être ajouté, si nécessaire.

Title: Drainage set for ureter drainage
Inventor: SCHNEPP-PESCH WOLFRAM
IPC: A61M25/01
Filed: 1990-05-29
Abstract: A drainage set is proposed, in particular for ureter drainage, with a drainage line (3), a guide mandrel (4) and a slide (5), in which, for optimal control of the line, in particular as regards its angular orientation, but also in order to permit a withdrawal of the line which has been inserted into a body cavity, it is proposed that the guide mandrel (4) should have a thickened area (41) formed integrally thereon, on which thickened area the drainage line (3) can be pushed via its lumen with frictional engagement, and it is proposed that the diameter of the lumen of the slide (5) should be greater than or equal to the diameter of the thickened area (41), but smaller than the external diameter of the drainage line (3). There is also the advantage that drainage lines (3) open on both sides can be positioned in the human body using the arrangement according to the invention. <IMAGE>

Abstract: The invention relates to a fibre-optic gyroscope (1) of the Sagnac type comprising a light source (21), a fibre coil (31) of an optical fibre (32) and a receiver arrangement (22, 23, 24), all of which are connected to a directional coupler (2), in such a manner that wideband light of the light source (21) is fed into both ends (7, 8) of the fibre coil (31) and passes through this coil in opposite directions, the light emerging from the ends of the fibre coil (31) into the directional coupler (2) interferes with the light fed in in a coupling area (11) and the interference light is picked up with the receiving arrangement (22, 23, 24). To achieve high sensitivity both for low and for high rates of rotation for such a fibre-optic gyroscope, it is proposed, in accordance with the invention, that the directional coupler (2) is connected to an auxiliary coil (41) into which light is also coupled from the single light source (21), the dimensions of the auxiliary coil (41) and of the main coil (31) being dimensioned with respect to their length and their diameter in such a manner that a measuring range is obtained which is extended by the auxiliary coil (41) and in which unambiguous measurement values for the rate of rotation of the fibre-optical gyroscope (1) can be determined for the entire measuring range. …<IMAGE>…

Abstract: The invention relates to a fragmentation projectile (1), in which the explosive (5) is surrounded by at least two projectile casings (2,3,4,4',4"), the casing (4,4',4") nearest the explosive (5) having a specific predetermined structural zone (7,7',7"), by means of which the projectile (1) generates reproducible fragments during the detonation. 
<??>To manufacture simple fragmentation casings, with which a desired combustion effect is additionally associated, it is proposed that the structural zones (7,7',7") consist of predetermined regions of a wall thickness smaller than that of the parts of the casing (4,4',4") which surround the structural zones, so that the shock wave occurring during the detonation is transmitted to the nearest casings (2,3) with a local time offset and thus reproduces the intended fragment form. A combustion composition (6) is additionally arranged on the side of the casing (4,4',4") facing the explosive (5). 
<??>The structural zones (7,7',7") should preferably be arranged on the side of the casing (4,4',4") facing away from the explosive (5).

Abstract: An electromagnetic clutch is disclosed which includes a rotor having a first friction surface and an armature plate having a second friction surface. Both first and second friction surfaces face each other. An annular friction member (60) of non-­magnetic material is fixedly disposed within a second annular groove formed at the second friction surface of the armature plate. A top end surface of the friction member projects with respect to the second friction surface of the armature plate. The first friction surface of the rotor is provided with a first annular groove (153c) to receive the projecting portion of the friction member. Therefore, the depth of the second annular groove be­comes large. Thereby, reduction of the number of magnetic lines of flux which radially penetrate through an annular portion of the armature plate remained at a location of the second annular groove is prevented. Thus, the magnetic attraction between the armature plate and the rotor is increased without increasing the weight of the electromagnetic clutch.

Abstract: A web transport apparatus that will not cause the web (1) to break by exerting external forces in different ways on two lateral sides. The transport apparatus (2) includes a group of pins that are studded on flat plates connected together to form a chain on either side of a web so that it is transported in multiple stages as it is retained on two lateral sides. An annular member (6a, 6b) supports the web from the inside by means of pins in each of the reversing sections that rotate to reverse the direction of web transport, with the piercing end of each pin facing either inward or outward. The annular member has a central shaft (5a, 5b) located at the center of the locus of rotation of the flat plates and has an outside diameter substantially equal to the diameter of the locus of rotation of the web. Preferably, the annular members rotate at the same speed as the web. There further may be provided a separating section (4) at which the web is disengaged from the pins, which section is provided in the last reversing section which rotates with the piercing ends of pins facing outward. The annular member in the last reversing section preferably has an outside diameter equal to or greater than the diameter of the locus of rotation of the piercing ends of the pins.

IPC: F16K11/044
Filed: 1991-03-28
Abstract: Water supplied from a mixing faucet or combination set via an inflow chamber to a change-over valve effects by impact pressure that a double-sided valve member-as a result of an asymmetrical arrangement between a first valve seat and a second valve seat-moves to the first valve seat, thereby blocking the supply to a shower outlet. Therefore, the water is conducted via the second valve seat into a bath-tub outlet. By actuating a draw-button, the double-sided valve member is reversed in order to block the bath-tub outlet and release the shower outlet. Impact pressure now effects self-locking in this position. When the water is turned off and impact pressure no longer prevails, the two-sided valve member thereupon moves into an inoperative positon by the force of two mutually counteracting springs. The conduit leading to the shower is automatically emptied by means of an annular gap remaining between the first valve seat and the double-sided valve member. It is thus precluded that bacteria can multiply or be reproduced in standing water.
