Patent EP-0331773-A1 (EP)
Inventor: DE BEER R H M
IPC: A61B5/097
Filed: 1988-03-08
Abstract: The flow resistance tube for gas flow meters, such as are used especially for breath monitoring, has a diaphragm element (3) which is arranged between two measuring connections in the region of a tube widening and which is formed by a polygonal section, joined to one side, of a membrane (2) arranged transversely to the gas flow in the tube (1) and forms a dynamic flow resistance depending on the flow velocity by elastic deflection in the direction of flow. To optimise the linearity of a differential pressure signal detected by an electronic differential pressure meter, the slot width (b) of the parting line (22) between the contour of the diaphragm element (3) and the contour of the diaphragm section in the membrane (2) is selected according to the invention to be between 0.1 and 0.5 mm, while the membrane, with the preferred use of a "Mylar< TM >" film, has a thickness of between 50  mu m and 125  mu m. For further improving the linearity of the differential pressure signal, in particular in the case of relatively large air throughputs, the transition regions on the inner wall of the flow resistance tube are shaped continuously and rounded, and the equation L DIVIDED D >/= 1 applies to the ratio of the diameter D of the tube widening to (half) the length L of the tube widening. <IMAGE>

Abstract: A fastening system for securing an article (14) to a base (15) uses a conventional drive fastener (12). A reaction surface (21) on the article contacts the bearing surface (18) on the underside of the fastener head (19) causing the fastener head to tilt relative to the body (13) of the fastener. The reaction surface also causes the body of the drive fastener to deform when it is fully driven into the article, and a portion of the material (27) from the reaction surface is displaced into the aperture (16) to increase the retention force of the fastener.

Abstract: The expansion dowel, consisting of an anchor bolt (1) and an expansion sleeve (2), is radially enlarged by driving the expansion sleeve (2) onto a broadening (1e) of the anchor bolt (1), and is anchored in the drilled hole. The broadening (1e), designed as a concave bulge, results in an increasing conicity in the insertion direction, as a result of which the subsequent expansion of the expansion dowel is limited. Cutting teeth (2d, 2e, 2f), which are arranged on the front end region of the expansion sleeve (2) and have a saw-tooth-shaped profile, deposit a proportion of the retention material on the wall of the drilled hole, when the expansion sleeve is driven forward, and thus create an undercut. In order to attain easier deformability, the expansion sleeve (2) is provided on its outer side with a ring slot (2g) in the region adjacent to the cutting teeth (2d, 2e, 2f) in the direction opposite to the insertion direction.

Abstract: The invention relates to bulletproof woven fabrics composed of filaments or yarns having high strengths and high moduli and consisting of polymers having ultrahigh molecular weights, the warp filaments or yarns consisting of other polymers than the weft filaments or yarns. By virtue of this arrangement the mutual friction of the warp and weft filaments is increased, so that impacting projec­tiles are no longer capable of moving these filaments aside as is the case, for example, with existing bulletproof fabrics made of polyolefin warp and weft filaments.

Abstract: An auxiliary gas generator (28) is used to provide gas for steering and pointing control of a multi-stage rocket motor system (1) to final interception manoeuvering stage (14) at the forward end thereof. During lower stage operation, this gas is routed through the "Divert" thrusters (38) of the final interception stage through a check valve (36). When control is not required, the gas can be either dumped through all thrusters or all thrusters can be closed and the gas dumped into the lower stages (54,56). As each of the lower stages is burned out, it is discarded. Using one or more gas generating propellant packages (42,44,46) provided therein, the final interception stage manoeuvers to the target.

Date Jun. 1, 1989.A main mirror for a reflecting telescope comprises plurality of individual polygonal reflecting elements (1 to 11) and positioning and adjusting elements (12) connected thereto. Prior art main mirrors of this type have a poor capacity for transmitting ponint images and for modulation and are unsuitable for use in the infrared region, because the positioning and adjustment elements, in particular the measurement sensors arranged in the region of the separating lignes between the individual polygonal reflecting elements (1 to 11) emit interfering thermal radiation. Furthermore, the polygonal reflecting elements (1 to 11) of prior art main mirrors (20) are expensive to manufacture. In order to remedy these drawbacks, the reflecting surface forms a complete circle by means of connecting reflecting elements (1 to 8) connected radially to the outer edges of the polygonal reflecting elements (9), the reflecting elements (1 to 11) are made from a lightweight preformed material, and the positioning and adjustment elements (12) are arranged below the reflecting elements (1 to 11).

Abstract: An integrated paver (20) comprising a self-propelled chassis (22) having a paving apparatus, such as a screed (24), supported on its rear end and a lifting conveyor (26) supported on its front end. The conveyor (26) is capable of picking-up loose paving material (64) laid in the windrow on the road surface. It is pivotally supported (42) on a mounting (44) which is in-turn pivotally supported (46) on the chassis (22) such that the conveyor (26) can be adjusted in two dimensions relative to the chassis (22). Grade controls (82) on the conveyor (26) control hydraulic cylinders (68, 70) to adjust the tilt and grade of the conveyor (26) relative to the road surface. Alternatively, the conveyor (26) can rest, by force of gravity on runners (94) which slide along the ground and hold the conveyor head a predetermined height (possibly zero) above the ground. Additionally, the runners (94) can be linked to floating break-away scrapers (114) which are maintained at a set position relative to the runners (94). The conveyor drag chain (56) rides over an idler shaft (60) above and in front of the inlet end supporting shaft (58) of the chain such that the paddles (62) on the chain travel at close to 45° to the road surface to reduce vibration and the slapping action of the paddles (62) against the windrow.
