IPC: H03J5/24
Filed: 1986-10-01
Abstract: A television tuner for three frequency bands (I, II, III) exhibits a common antenna terminal (4) for corresponding input filter circuits. The input filter circuits (1, 2, 3) of the two upper frequency bands can be connected to or disconnected from the antenna terminal via switches (11, 12). The switches (11, 12) are in each case located between the antenna terminal (4) and the associated input filter circuit (2, 3). To achieve improved matching of the input filter circuit (3) and for a simple circuit configuration, the antenna terminal (4) is spatially allocated to an input filter circuit (1, 2) of the two low-frequency frequency bands (I, II). In addition, the switch (12) of the highest frequency band (III) is connected to the end of a coupling conductor (5) which is spatially next to the antenna terminal (4). Both ends of the coupling conductor (5) are connected to earth via in each case one capacitor (5a, 5b), the coupling conductor being coupled to an output circuit conductor (6) of the input filter circuit (3) of the highest frequency band (III). <IMAGE>

IPC: H01Q1/12
Filed: 1987-03-24
Abstract: A method is specified for manually fitting on an upright tube a microwave aerial with a plane reflector by means of a fastening device arranged on the rear side of the latter, in which, to achieve as little outlay as possible, a fitting aid equipped with a hanging device and a clamping clip is detachably fastened on the upright tube by means of the clamping clip, the microwave aerial is hung by an element of its fastening device into the hanging device, the clamping clip being arranged in such a way that the hung microwave aerial is at least roughly aligned in the desired azimuth position, the microwave aerial is fastened on the upright tube in the desired azimuth position with the aid of the fastening device and finally the fitting aid is detached again from the upright tube. In the case of a preferred fitting aid for carrying out this method, the hanging device has two hook-shaped receiving elements, which can be hung in the microwave aerial by a corresponding part of the fastening device and which are designed and/or arranged in such a way that the hung part lies perpendicularly with respect to the upright tube. It is particularly advantageous in this case to design the hanging device such that it can be swivelled with respect to the swivelling clip fastened on the upright tube in a plane perpendicular to the upright tube.
Patent DE-3716298-A1 (DE)
Title: Drive-in anchor
Inventor: HAAGE MANFRED
IPC: F16B13/12
Filed: 1987-05-15
Abstract: Known as fastening elements for insertion into bores of a masonry structure are drive-in anchors, which are anchored in the bore simply by driving them in. In this arrangement, expansion of the drive-in anchor can take place in the region of an expansion zone. In order that the drive-in anchor may also be used in rectilinear bores, its shaft is configured in the form of a sleeve and is tapered conically in the region of the expansion body. An expansion pin located in the shaft can be driven into the expansion zone, as a result of which the expansion body and an expansion ring enclosing it are expanded. The drive-in anchor is suitable both for rectilinear bores and also for bores with undercuts, and it also fulfils high safety requirements since it has an automatic follow-up expansion function.

Title: Connection sleeve for injection hoses
Inventor: BERGER WOLFGANG DR ING
IPC: F16L31/02
Filed: 1987-05-21
Abstract: Injection (grouting) hoses comprise fabric-like hose sheathings, in which a channel cross-section is kept open by a steel coil or perforated plastic tubes. To be able to inject the plastic, the injection hoses must be connected via impermeable connection hoses to the pump. Since the hose lengths to be injected must not become too great, that is to say relatively long lengths have to be subdivided into smaller injection sections, there is no alternative but to cut up the injection hose in order to be able to attach to the ends produced connection hoses which are led out of the concrete and to which the pump can be connected. The subject of the application provides the possibility of interconnecting two injection hoses and avoids the cutting up of the injection hoses into particular lengths. It allows the concrete to be injected from every point of the injection hose.
Patent DE-3721973-A1 (DE)
Title: Sealing device
Inventor: ABELE BERTHOLD W
IPC: H02G3/22
Filed: 1987-07-03
Abstract: For the purpose of sealing telephone cables run through wall passages, two discs (plates) are provided as holding parts, which are braced axially with respect to each other by means of rods. A plastically deformable sealing material is introduced between the rods. This sealing material is spread inside the passage in an uncontrolled manner upon bracing the holding parts, so that a faultless sealing is not ensured. In order to achieve a defined, gas-tight sealing with respect to the cable and the uneven wall surfaces of the passage, the sealing device has an opening for the cable, the sealing for sealing the cable being provided in the opening and the sealing for sealing the passage being provided in the region outside the passage on the holding parts. As a result of the separate sealing of the cable and of the wall passage as well as of its sealing outside the passage, a faultless sealing can be ensured even in the case of uneven boundary surfaces.

Title: Anti-release device for windows, doors or the like
Inventor: DAHEIM HANS-ALBERT
IPC: E05C9/18
Filed: 1987-10-07
Abstract: To make it difficult to actuate the wing frame (2) of a window, door or the like in its closed position in an unauthorised manner, the invention provides an anti-release device which can be actuated independently of the locking mechanism of the wing frame (2) and which cooperates with the push rod (8) of this mechanism. At the same time, a blocking member (9) in the inner wall (5) of the wing frame (2) is guided so as to be movable perpendicularly to the wing plane counter to a spring effect (15). By means of a laterally projecting extension (10), the blocking member (9) engages into the push rod (8) and blocks the movement of the latter. In order to open the wing frame (2), the blocking member (9) has to be moved, so that the push rod (8) is freed from the extension (10) of the blocking member (9). <IMAGE>

Title: Method for pouring liquids into bottles
Inventor: BROLL ADALBERT
IPC: B67C3/26
Filed: 1987-12-15
Abstract: The object of the invention is to implement an adjustment to the filling level after the filling process in the event of overfilling by the introduction of inert gas into the bottle without impairing the pressure system of the filling machine while making very sparing use of inert gas and reducing losses of filling material. An essential feature is that after pouring into the lower filling valve region when the return gas valve is closed and the inert gas source is closed, a metered quantity of inert gas which is at a pressure which is greater than the loading gas pressure by an adjustable differential amount is introduced into the annular boiler, the froth formed during pouring is compressed and, when the return gas duct has been opened, the adjustment amount of liquid is forced through the return gas duct back into the annular boiler, after which the return gas duct is closed. The invention is used for pouring liquids into bottles and relates to a method in which adjustment of the filling level follows the filling process. <IMAGE>
