Title: Soundproofing shield
Inventor: WOLF ANTON DIPL PHYS
IPC: B60B7/00
Filed: 1983-08-06
Abstract: In order effectively to reduce in broadband fashion the traffic noise emitted by automobile tyres, the invention presents a soundproofing disc which can be mounted in the manner of a wheel cap on the wheel rim and in which there is formed a multiplicity of broadband resonator cavities which are situated closely next to one another in the circumferential direction of the disc, open on one side towards the outer rim of the disc, are tapered in the shape of a funnel and are finished in a sound-absorbing fashion at least in the region of their inner, restricted end section. The cavity openings are cleared as a function of speed by an elastic, resiliently pretensioned sealing lip on the outer rim of the disc, and the distance present between the outer rim of the disc and the road is reduced at a relatively high wheel speed, and the screening effect thereby improved. <IMAGE>

Title: Closing-sequence device for a two-wing door
Inventor: JENTSCH DIETRICH
IPC: E05F5/12
Filed: 1983-10-08
Abstract: In a two-wing door comprising a stationary wing and a passage wing, its door wings can each be moved by a drive means, such as a door closer, acting in the closing direction, and can be regulated in their closing sequence via a pivoting rod arranged between the door frame and passage wing for the purpose of fixing the latter so as to keep open the pivoting range of the stationary wing. To achieve a visually pleasing closing-sequence regulating device which is simple to construct and produce, the pivoting rod is articulated at one end on the passage wing and is held at the other end by means of a bolt so as to be displaceable in a guide rail assigned to the door frame. At the same time, the bolt can be fixed in the guide rail by a blocking member which can be actuated by the stationary wing.

Title: Ultrasound interface
Inventor: JAHN HELMUT
IPC: G10K11/02
Filed: 1984-08-14
Abstract: The invention relates to an interface for an ultrasound oscillation exciter which is provided for examining an object, having an interfacing medium whose speed of sound is matched to that in the object. In order largely to preclude reflections on gas bubbles and vagrant particles, and hence largely to preclude disturbances in the image representation of ultrasound echo signals, it is provided according to the invention that the interfacing medium is a gel. The gel is preferably a polyacryl amide gel; the latter has the advantage that it can be produced easily, can be handled easily and has acoustic and elastic properties which are adjustable within certain limits. Furthermore, the speed of sound in this gel is close to that in the human body, and the impedance is also correspondingly similar, so that it is specifically suitable for use in a medical-diagnostic ultrasound apparatus. <IMAGE>

Title: Elastically flexible joint, especially for axle links of commercial vehicles
Inventor: HORNUNG WALTER DIPL ING
IPC: F16C11/04
Filed: 1984-10-19
Abstract: What is described is an elastically flexible joint for a structural part, for example axle link, which executes only angular movements, the joint head of which joint is seated, for the purpose of radially and axially flexible mounting, on an elastomeric bush arranged on a pivot pin. In operation under practical conditions, the joint head, especially when incorrectly assembled, can be shifted axially, under the influence of forces directed along the joint axis, to such an extent that it comes so near to the pivot-pin base or to a plate held on the pivot pin and intended for mounting the joint head that problems of noise and of strength can arise as a result. An axial shift of this kind can be avoided if there is provided within the joint head, approximately in the middle region, an annular web, the inside diameter of which is larger than the pivot-pin diameter, and if the elastomeric bush is formed by two bush portions which bear with their inner end face against the annular web. In the event of an axial shift of the joint head, this annular web acts as a stop which, in cooperation with one of the two bush portions, generates progressive shift resistance.
