Patent DE-3501143-A1 (DE)
Title: Method of constructing a tunnel lining
Inventor: BUCHMANN HEINZ DIPL ING
IPC: E21D11/15
Filed: 1985-01-15
Abstract: The invention relates to a method of constructing a tunnel lining with the use of a shield driving machine. In the protection of the shield, the ring segments belonging to a ring are positioned one after the other and are joined to one another by welds running in the longitudinal axis of the tunnel. By rotating the segments, already joined to one another, about the longitudinal axis of the tunnel, it is ensured that the weld, running in the longitudinal axis of the tunnel, between each two segments can always be made in the area of the tunnel floor. Only after the ring is complete is it pressed against the existing tunnel lining and attached to it by means of a circumferential weld.

Title: Method for producing the curved, disc-shaped winding of a magnet, and a device for carrying out this method
Inventor: LANG WILHELM
IPC: H01F41/04
Filed: 1985-09-20
Abstract: The curved, disc-shaped winding of a magnet can be produced using the method, the conductors in the first winding which is to be produced being arranged around a central core region having a convex outside and a concave inside, and finally being fixed in this position. The method is intended to make large-scale production of curved magnet windings possible in a comparatively simple manner. For this purpose, the conductors are initially wound, under tension, around a provisional, circular winding former (13) having a specific circumference, in order to form a provisional winding (12) and, after removal of the winding former (13), the conductor parts (12a) of the provisional winding (12') which are then exposed and are intended to form the region of the concave inside (10) of the curved winding (2) which is to be produced are pressed onto the convex outside (18) of a moulding (17) whose curvature is matched to the curvature of the concave inside (10) of the curved winding (2) which is to be produced, the remaining conductor parts of the provisional winding (12', 12'') being drawn to the central core region (3'). <IMAGE>

Title: Pipe holder
Inventor: ELTER CLAUS DR ING
IPC: B01J3/00
Filed: 1986-01-29
Abstract: The invention relates to a pipe holder on a curved bottom head of a double-walled pressure vessel whose inner vessel shell is connected to a pipe of a first pipeline for hot pressure medium, in particular hot gas of a high-temperature reactor, and whose outer vessel shell bounds an external pressure chamber which serves as a leakage boundary and is connected to at least one pipeline for cold pressure medium, in particular cold gas of a high-temperature reactor. The pipe holder is connected to one pipeline in a rigid manner and to the other pipeline by means of a compensator. It is held by means of articulated supports which are joined to brackets which are supported over a large area on the outer vessel shell to which they are welded, and thus serves to equalise different thermal expansions induced by the temperature.

Title: Filter for fuels
Inventor: FERCH ALOIS
IPC: B01D29/11
Filed: 1986-03-24
Abstract: The proposed filter which can be introduced into a fuel container, has an elastic framework composed of a thermoplastic. The framework supports an elastic permeable plastic filter cloth. The filter further has a connection piece (2) for the fuel pump and for the fuel line. The connection piece (2) faces the fuel filler opening arranged on the container. The fuel enters from the exterior through the filter cloth into the interior of the filter and is passed on from there through the connection piece (2). The ratio of the height of the filter to its maximum width is 1:3 to 8. The connection piece (box 3) for the fuel line is arranged centrally and is firmly attached to the framework. The framework is composed of elastic, radially-running shoulders (5) and ribs (6) which are arranged in the central area of the filter and are firmly attached to the cloth and the elasticity of which increases from the centre of the filter body towards the filter rim. <IMAGE>

Title: Circuit arrangement for adaptive echo cancellation in terminals for duplex transmission
Inventor: HESPELT VOLKER DR ING
IPC: H04B3/23
Filed: 1986-03-27
Abstract: The invention relates to a circuit arrangement for adaptive echo cancellation in terminals for duplex transmission by obtaining an echo cancellation signal (ê) from a transmit signal (xA) by means of a first (AF) and a second (F) filter, the first filter being designed as an adaptive transverse filter and the second filter being connected downstream of the first. If a relatively long echo is intended to be completely cancelled with an echo canceller comprising a single adaptive transverse filter, this filter must have an economically unviable number of elements. It is known for the transverse filter to be equipped with fewer elements than are needed for complete echo cancellation. Only part of the echo is thereby cancelled. A second filter is connected downstream of the transverse filter to cancel the echo end which thus remains. According to the invention, the second filter (F) is operated non-adaptively and is connected downstream of the first filter in such a way that the output of the last multiplier (Mn) of the first filter (AF) is connected to the input of the second filter (F) (Fig. 1). <IMAGE>

Patent DE-3622415-A1 (DE)
Inventor: GOESSLER GERHARD
IPC: F24C15/10
Filed: 1986-07-03
Abstract: In a radiant heater unit (1) for heating through a hotplate (2), the periphery of the heating field is formed by an initial cooking marginal heating system (9), which is e.g. operated by a short-circuit connection (19), so that it passes much more rapidly from the cold state into the visible glowing state and also in the marginal region use is made of the faster heat transfer there to the bottom (3) of the cooking utensil. The increased radiant power density can also be obtained by other measures, namely by modified insulating conditions in the vicinity of the marginal heating system, by using a PTC resistor in the vicinity of the inner partial power system and similar measures.

Title: Catch device for planetary gearing
Inventor: JAKSZTAT KLAUS
IPC: F16D59/00
Filed: 1987-06-29
Abstract: The invention concerns a catch device that can be used in planetary gearing as a stop for the gearing dependent on the direction of rotation. It is intended preferably for small hoisting gear. The objective is to use little material and manufacturing and maintenance effort without impairing the functionability or reliability of the catch device. The task of the invention is to design a catch device of uncomplicated construction, that utilises the gearing kinematics for automatic initiation of the stop action, influencing the efficiency of the gearing, and that can be used as an overload protection. The invention provides for a wedge-shaped or single-angled or double-angled catch element, which is in contact with the plane or end faces of the gear wheels when acting as a catch. For cancelling the catch action, there is an actuating element that can turn relative to the primary drive, and switching parts that engage with the catch element and the primary drive positioned movably or fixed on it. <IMAGE>
