Patent DE-3744614-A1 (DE)
Title: Loudspeaker combination
Inventor: MATSUHASHI HISASHI
IPC: H04R7/12
Filed: 1987-12-31
Abstract: The loudspeaker combination is constructed of a number of diaphragms which are arranged coaxially to one another, each of which responding to a different frequency range (coaxial loudspeaker combination). A conical diaphragm (2) for the centre frequency range is connected to a coil former (6). A diaphragm (1) for the low-frequency range, the inside diameter of which is almost equal to the diameter of the conical diaphragm, is coaxially connected to the conical diaphragm. The low-frequency diaphragm can be constructed in such a manner that, together with the conical diaphragm for centre frequencies, it forms a cone shape but it can also be flat and attached level. The loudspeaker combination can be provided with a V-shaped groove (21) underneath the low-frequency diaphragm for increasing the mechanical rigidity, the V-shaped groove carrying the diaphragm at the section which is connected to the conical diaphragm and the outer edge of the low-frequency diaphragm. <IMAGE>

Title: Shuttering support and shore for the building trade
Inventor: WENNGATZ WALTER
IPC: E04G11/48
Filed: 1988-03-26
Abstract: The support comprises a synthetic-resin tube which is reinforced with glass fibre and into which a bundle of small glass-fibre-reinforced synthetic-resin tubes is pushed and adhesively bonded. The head piece, foot piece and intermediate piece consists of V2A steel in order to prevent corrosion. By virtue of the intermediate piece, the support and shore can be lengthened to any extent. Each support and shore must therefore have a standard length. For example, support 2 m, adaptor pieces 30, 40 and 50 cm. Or support 2.60 m, adaptor pieces the same as before. Of course, the structure of the support and shore can also be used in greater lengths. The support for exterior scaffoldings and falseworks. The shore for duct construction work. Since the structure is very lightweight, very durable and corrosion-resistant, it constitutes a real alternative to the prior art.

Inventor: BECHER NORBERT
IPC: F23D11/40
Filed: 1988-04-18
Abstract: In the case of an oil burner with an oil-spraying device which is arranged in an air supply tube or the like fed by a blower and surrounded by a ceramic fire tube which projects, seen in the flow direction, beyond the air supply tube and at least partly surrounds the latter, as far as possible at a short distance, there is provided a protective device for the ceramic fire tube which not only preserves the functioning thereof in terms of firing, but further increases its efficiency, if necessary, and as a result of its construction and/or arrangement contributes to keeping off blows and/or impacts and the like on the ceramic fire tube. This device, which is constructed in particular as a protective tube which surrounds the fire tube at a distance, should be combined with the fire tube to form a structural, easily replaceable unit.
Patent DE-3814804-A1 (DE)
Title: Device and method for regenerating ink ribbons
Inventor: WOLLENBERG GEB OSTERKAMP
IPC: B41J31/14
Filed: 1988-05-02
Abstract: The problem is that ink ribbons on a textile basis for office machines are expensive, time-consuming, produce a great amount of dirt and do not guarantee a constant intensity of the ink. They are disposable articles which are harmful to the environment. The solution is a device on cartridges and reels which allows the user to open the ribbon container when required and to soak the ribbon directly with fresh refilling ink. The result is a service life of the cartridges and reels which has already been proved to be expedient in practice and is many times longer with a constant intensity of the ink which can be regulated without difficulty. Environmentally friendly and very cost-effective.

Abstract: The invention relates to a binocular telescope having cardanically journalled inverting systems mounted on a symmetrical double holder. This double holder is connected via a spring joint to a stationary non-movable base frame which is mounted at the pivot point of both inverting systems. A passive movement damping device provides for a field image stabilization in the telescope. The monolithic spring joint has a spring arrangement perpendicular to the optical axis with the springs being thickened in the axial direction toward the edge to improve supporting capability. Shock protection is provided in the region of the support pivot point and contains an unlatchable device. The passive damping device is configured as an eddy current device and includes a magnetic system about a stationary eddy current coil which has a nonlinear effect for the purpose of adjusting axially the damping constants. Isolated coils are disposed on the eddy current plate and can be short-circuited by means of a switch so that a specific, time-limited change of the damping constant is possible.
