Abstract: A device for producing sensory stimuli for a child by means of a body made of an elastic material and a bellows which is embedded in the elastic material of the body, including a first converter device for generating a fluid flow for moving a lying surface for a child, a second converter device for generating sound in a fluid, which corresponds at least to either heart sounds or human speech or music, and a fluid line for simultaneously conducting the fluid flow generated by the first converter device and transmitting the sound generated by the second converter device to a bellows in a body made of an elastic material.

Abstract: A device for generating sensory stimuli, corresponding to sensory stimuli emanating from a reference person, for a child comprises a receiving unit for receiving a data stream from a device for acquiring sensory stimuli, emanating from a reference person, and a transducer unit, which is coupled to the receiving unit and is controllable by the data stream. The transducer unit generates at least either body-borne sound, which corresponds to the heart sounds, described by the data stream, of the reference person, or movements, which correspond to the movements, described by the data stream, of the reference person, or airborne sound, which corresponds to the airborne sound generated by the reference person and is described by the data stream.

Abstract: A set of dental implants comprising two implants each having an anchoring head for a structural element and having an end face of a predetermined face diameter and a screw element with a thread core and a self-cutting outer thread. The thread core and the outer thread have three segments following one another in succession from crestal to apical, namely a crestal segment adjoining the anchoring head with a constant outer crestal diameter of the outer thread and a thread core conically tapering in the apical direction to a predetermined intermediate diameter, a middle segment with an outer diameter of the thread core substantially equal to the intermediate diameter, and a tip segment with an outer thread of an outer diameter tapering in the apical direction and a conically tapering diameter of the thread core. The face diameters of the two implants are different.

Abstract: The invention relates to a dental implant (1) comprising an anchoring head (2) for a structural part (15), and a screw element (3) having a thread root (8) and a self-cutting external thread (9). The thread root (8) and the external thread (9) form three succeeding sections from the crest to the apex, in which the outer diameters of the external thread (9) and the thread root (8) change in a specific manner.

Abstract: A bandpass filter, includes a series of waveguide resonators positioned along a common longitudinal axis so as to define at least a first resonator and a last resonator, whereby adjacent resonators are mechanically linked to one another by a common coupling plate of sheet metal member which is formed with coupling slots for electrically coupling the resonators, with the first and last resonators each being closed by an end plate of sheet metal.

Abstract: A broadband coaxial overvoltage protector includes a short-circuit line segment connected in parallel with a coaxial line section, a transforming coaxial line section with a length <&lgr;/4, with one end of the transforming coaxial line section connected in series to the coaxial line section, and an open-circuit line segment connected in series to the other end of the transforming line section. The length of the transforming line section is selected in such a way that the curve representing the frequency dependence of the reflection coefficient for two different operating frequencies, which may be widely spaced, has a respective minimum at each of the two frequencies.

Abstract: Spring-tension pliers are disclosed having two clamping arms (2, 3) mounted see-saw fashion on a pivot pin (1), the arms forming a handle (4) with their legs, the legs being pivotable toward one another against the force of a spring (5) to open a clamping mouth formed by the other ends of the legs (6), with clamping jaws (7) being associated with the free ends of the clamping legs (6). The clamping jaws (7) are pivotable around a pivot axis (8') parallel to the pivot joint axis, end sections (9) of the clamping legs are rounded concentrically with respect to jaw pivot axis (8'), and these rounded areas (11) each fit into a correspondingly rounded recess (10) of the clamping jaws.

Abstract: An implant for the jawbone includes a shaft portion and a conical retention portion which is provided with displacement projections. The displacement projections are sickle-shaped retention wedges which are provided on the retention portion located opposite each other. Since the retention portion is conical and the retention wedges result in an oval cross-section, the implant can be inserted into the prepared alveolus having the same shape and a rotation of at most 90.degree. results in locking of the implant in the interradicular alveolar bone to provide primary stability.

Abstract: An optical fiber plug-in connection includes a coupler with a coupler centering sleeve, a coupler sleeve centrally retained within the coupler centering sleeve and a fiber containing coupler pin accommodated in the coupler sleeve. The coupler cooperates with a plug which includes a plug centering sleeve insertable in the coupler centering sleeve, a cable clamp supported in the plug centering sleeve, and a fiber containing plug pin which is radially elastically supported relative to the plug centering sleeve.

Abstract: An emergency hammer for smashing panes of glass is disclosed. The hammer includes a handle and a hammer head on the handle. The hammer head has a point at one end and is connected to the handle at the opposite end. The hammer head may be integrally attached to the handle. The hammer head thus protrudes a substantial length from the handle in only one direction. A protective loop of a relatively rigid and dimensionally stable material is also on the handle and extends in the same direction for covering the hand of the person grasping the handle.

Abstract: A waveguide device for producing absorption or attenuation includes a waveguide section which is provided with an external absorber material. For allowing a transfer of the high-frequency power into the absorber material, the wave section is provided with coupling apertures via which the absorber material is in connection with the interior of the waveguide section.

Abstract: A waveguide usable as absorber or as attenuator for high radio-frequency powers up to highest frequencies includes a tube with a dissipative material at whose inside a metallized layer is applied. The thickness of the metallized layer changes along the length of the tube with its initial thickness and end thickness determined in such a manner that a constant power density is obtained along the waveguide.

Abstract: For the transmission of a plurality of light channels between two parts which rotate relative to each other, an optical transmission element is arranged with its optical axis OA coaxial to the axis of rotation and light transmitters in different radial regions. By convex lenses or mirrors the bundles of rays coming from the light transmitters are parallelized and impinge on the optical transmission element which individually focuses the bundles of rays. In order to obtain an imaging scale of 1:1 a synchronously rotating rhomboid prism or a parabolic mirror can be used. In addition, HF channels can be transmitted.

Abstract: The invention relates to an HF terminating impedance in strip conductor technique in which the resistive layer is enclosed between two ceramic plates which are clamped from the outside by metallic heat dissipating plates, the freedom from reflection of the terminating impedance being ensured by the lateral edge lines of the resistive layer satisfying the condition ##EQU1## To ensure an intimate heat conduction contact between the resistive layer and the ceramic plates and the ceramic plates and the adjoining clamping plate without introducing bending stresses into the ceramic plates which might cause fracture, at the contact surfaces a soft metal foil, preferably of lead, is inserted which is prevented from cold flow by a rolled-in grating or netting, in particular of bronze or copper.
