Patent DE-3711804-A1 (DE)
Title: Metallated diazo compounds, their use as direct dyes, and after-treatment of the dyeings
Inventor: DOSWALD PAUL DR
IPC: C09B45/28
Filed: 1987-04-08
Abstract: Metallated diazo compounds of the formula I <IMAGE> as the free acid or in salt form, the individual symbols being as defined in Claim 1. These compounds are employed in the dyeing or printing of organic substrates which contain hydroxyl groups or nitrogen, and preferably for textile material consisting of or containing cellulose fibres. A particularly preferred substrate is cotton, on its own or as a blend with other suitable textile fibres. The wash fastness of the dyeings and prints obtained on cellulose-containing textile material can be improved further by after-treatment with a special, polymeric, polybasic amino compound (A).
Patent DE-3717755-A1 (DE)
Title: Adder circuit in 5211 code
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1987-05-26
Abstract: The main circuit (2) of the adder circuit according to the subject of the invention does not consist of individual adder circuits, because the AND circuits which are used are driven at one input by a through line p, and only process the value 2. For processing the value 1, a dual full adder (6) is required, and for processing the value 5, a dual full adder (7) is required. The main circuit (2) consists of eight AND circuits 9 each with two inputs, and nine OR circuits 10 each with two inputs. If the intermediate result number is greater than the number 4, a partial sum with the value 5 is derived from this and processed in the dual full adder (7). Circuit (4) is a one upwards shift circuit, which is combined with a straight-through circuit. <IMAGE>

Patent DE-3801701-A1 (DE)
Title: Structure-borne-sound-insulating/fastening device
Inventor: MANTEL JUVAL DR ING
IPC: E04F15/20
Filed: 1988-01-21
Abstract: Sructure-borne-sound-insulating/fastening devices for fastening by means of screws or nails, e.g. panels or rails on walls or floor panels on wooden floors. Wherever objects are screw-connected on walls or ceilings, problems in terms of structure-borne sound arise, which can cause disruption in adjacent rooms. In the case of wooden floors, there is, for example, the problem of fastening the floor panels upon which it is possible to walk, e.g. parquet, on the substructure, it being possible for structure-borne-sound problems of the reduced footstep-sound-insulation type to arise. To avoid these problems, the following solution according to the invention has been worked out: insulating bodies which, on the one hand, are fastened on the wall or ceiling or subfloor structure and, on the other hand, serve to fasten wall panels, ceiling panels or floor panels can be used as an elongate rail or an individual body (see Figures 1 and 2), a basic panel partially enclosing the insulating layer and the core of the device. <IMAGE>
Patent DE-3802804-A1 (DE)
Title: House lead-in for gas
IPC: F16L5/12
Filed: 1988-01-30
Abstract: In the case of a house lead-in for gas, a metallic protective pipe is let into the building wall, into which pipe a gas line configured as a metal pipe and plastic pipe is arranged. The protective pipe is fixedly welded on the metal pipe of the gas line, whereas its other end is sealed towards the plastic pipe. For a simple, inexpensive and reliable configuration of the house lead-in, it is proposed to provide, on the plastic pipe, a plastic sleeve for the plugging-in of the metal pipe, this resulting in a shoulder transition at this location. The metallic protective pipe encloses the plastic sleeve and is drawn in radially at the shoulder transition, as a result of which the pipe end engages in a positively locking manner behind the shoulder transition.

Title: Electrical rocker switch
Inventor: BAER SIEGFRIED DIPL ING
IPC: H01H23/04
Filed: 1988-02-08
Abstract: The illustrated rocker switch, which is intended for electrical domestic appliances, has a two-piece housing. The interior contains stationary contacts and a contact rocker which can pivot and bridges the stationary contacts. The housing is split such that the plane of separation is at right angles to the pivoting axis of the contact rocker. The stationary contacts and the contact rocker which can pivot can be inserted loosely into holders, to be precise by being pushed into the interior of one of the housing parts, in the direction of the pivoting axis. The second housing part, which can be mounted on the first housing part, is then used to fix these parts. Removal of the contacts from their holders is no longer possible, as a result of the second housing part.

Abstract: An adhesive-applying apparatus is provided, which has a head on which there is rotatably mounted a rotating hollow applicator brush, which is driven by means of a drive device. The bristles are spread in the form of a hollow cone. An adhesive feeding tube, which is connected via a line to a metering pump and is thus fed with adhesive, opens out in this hollow cone. The rotating brush is assigned in a predetermined arrangement two distributing brushes, fixed to the frame. The arrangement can be passed over the surface to be provided with adhesive by means of a handle. However, the head is preferably designed as a carriage which can travel on a guide, the guide being supported movably by means of a carrying device and being controlled in such a way that, with the aid of a spacer, the bristles always assume a fixed relative position with respect to the surface to be provided with adhesive.

Abstract: A drive device for aircraft undercarriage wheels consisting of one or more wheels with vanes, which wheels are arranged on a plane in the form of a disc, which drive device is permanently and concentrically connected to the relevant wheel in each case. It is fitted to the wheel in such a manner that the wind of motion flows past it transversely with respect to the rotation axis and thus produces a torque corresponding to the rotation direction of the wheels, which torque causes the wheels to rotate corresponding to the direction and speed of the aircraft. The drive device according to the invention is fitted to each independently mounted aircraft wheel and results in each wheel being caused to rotate and accelerate until the circumferential speed of the tyre tread corresponds to the instantaneous airspeed.
