Patent DE-3141276-A1 (DE)
Title: Method and device for the centreless grinding of rotationally symmetric workpieces
Inventor: BLIESKE THOMAS
IPC: B24B5/24
Filed: 1981-10-17
Abstract: The object of the invention is to provide a method for the centreless grinding of the ends of rotationally symmetric workpieces as well as a device for carrying out this method, by means of which in particular the machining of workpieces of small diameter is possible with high accuracy. The method according to the invention is characterised in that the workpieces, transferred to a transport means in an unbroken sequence and lined up as a virtually continuous band, are guided with the ends to be machined over the grinding body as a result of the movement of the transport means on workpieces rolling on a counterstay means. The device pertaining to the invention ensures that the method is carried out under the conditions according to the invention. <IMAGE>
Patent DE-3144051-A1 (DE)
Title: Vacuum lift missile
Inventor: GRAF HELMUT ING GRAD
IPC: B64B1/06
Filed: 1981-11-03
Abstract: The vacuum lift missile is similar to earlier airships. However, its internal space is evacuated rather than being filled with a light gas. To this end, the stabilising frame is also constructed for reversed operation (external pressure instead of internal pressure). Because of the lift principle, this missile has a greater lift than the light-gas balloon and can be used in all fields of aviation, military reconnaissance, atmospheric research, and as a lifting device, scaffold, children's toy and in other fields. The advantages over other flying machines are the good vertical manoeuvrability, which is ensured by carrying the vacuum pump on board, the small cost outlay for propulsion and production, and finally the good environmental friendliness.
Patent DE-3202468-A1 (DE)
Title: Holding device for fence posts
Inventor: HOERNIS AUGUST
IPC: E04H17/06
Filed: 1982-01-27
Abstract: A holding device for fence posts in the form of a T-shaped support, for example of concrete, which has in one web part at the support ends through-holes for inserting the fence posts. The support rests with the web part on the ground, whereas the downwardly extending part of the flange of the T is embedded in the ground. The fence posts can be driven through the holes of the web part into the ground and are thereby firmly fixed. An additional hold can be obtained by means of clamping or holding straps on the flange part projecting upwards above the ground. Adjustment of the inclination of the fence posts is possible as a result of the adjustability of the holding straps longitudinally and/or transversely with respect to the support longitudinal direction. <IMAGE>

Patent DE-3222387-A1 (DE)
Title: Exhaust-gas channel, especially with a built-in silencer composed of slots filled with mineral wool, and rain-shielding device for this
Inventor: DE LANK GERD DIPL ING
IPC: F01N13/08
Filed: 1982-06-15
Abstract: In an exhaust-gas channel serving as a flue and having silencer fittings, there is a rain-shielding device (16) which consists of a multiplicity of lamellae (17) and of a collecting dish (18). The lamellae (17) form an acute angle with the mid-axis (20) of the flue, so that the flow of gas during passage through the rain-shielding device (16) is deflected only moderately, thus resulting in only a slight pressure loss. In order reliably to prevent rain liquid from penetrating into the lower flue portions, the respective upper edge (21) of the lamella (17) covers a lower edge region (22) of the lamellae (17), so that the total cross-section of the channel portion located below the rain-shielding device (16) is masked against the penetration of rain liquid. The advantageous effect of the rain-shielding device (16) is especially beneficial when it is built into narrowing transitional portions (15) of the flue, since, in these portions, the inclination of the lamellae (17) can be matched to the trend of the stream lines of the gas. <IMAGE>
Patent DE-3225190-A1 (DE)
Title: Process and product for cleaning spots off various textiles etc.
Inventor: HUNDSDORF HANS
IPC: C11D7/26
Filed: 1982-07-06
Abstract: Process and product for cleaning spots off various textiles etc., consisting of one part of methylated spirits 96%, one part of methylene chloride, one part of nitro lacquer solvent and 1/4 part of fatty acid. The parts are mixed together undiluted. The product and process removes greasy spots and very heavy soiling because the dissolving power is enormous. A clean cloth is used to apply the product, rubbing from the edge inwards, to the particular spot. It is subsequently possible, because the treated spot has become emulsifiable owing to addition of fatty acid, to treat with simple soap foam or mild detergent. No rings remain after drying. Dry cleaning is unnecessary.

Abstract: The invention relates to an electrical apparatus having an insulated circuit board (6) which is arranged parallel to a housing wall (3) of the apparatus and contains conductor tracks on its side pointing towards the housing wall, and having a slide switch which is arranged between the circuit board and the housing wall. A slide switch board (15) which is arranged parallel to the housing wall is guided and supported in a rectangular perforation (12) in the housing wall and, on its side facing the circuit board, contains parallelepiped pockets into which bridge contact springs (27) are inserted which rest against the circuit board (6) under spring pressure. The slide switch board is supported against the housing wall on sliding elements (14 and 33). The construction according to the invention makes it possible to have a very small distance between the circuit board and the housing wall, despite the arrangement of the slide switch on the circuit board. <IMAGE>

Title: Circuit arrangement for a telephone station with an answering machine
Inventor: FIMPEL FRANZ
IPC: H04M1/65
Filed: 1983-02-09
Abstract: The invention relates to a circuit arrangement for a telephone station with an answering machine, where the answering machine is automatically connected to the subscriber line after a specific number of ringing tones. The object of the invention is to allow the station subscriber to intercept an incoming message when the answering machine is in operation without de-activating the answering machine, to participate in the call himself if necessary and to record the call. This is achieved in that an earpiece can be connected via an additional repeating coil inserted in the subscriber line and, if required, a microphone can be connected via a matching network, where this connection does not interfere with the function of the answering machine which is connected in order to record the distant message. The inventive concept can be implemented in all answering machines which can be connected to a telephone station.

Title: Large-bale press for agricultural crops
Inventor: ACKERMANN GUSTAV DR ING
IPC: A01F15/14
Filed: 1983-07-28
Abstract: The present invention describes a large-bale press having driven winding rollers which limit the pressing space circumferentially and which are mounted in side walls, parts of these side walls being pivotable downwards for the purpose of ejecting a finished bale. Connected to the bale press is a supply container for a web roll, from which, after the formation of the bale has taken place, first the web start is guided by means of drawing-forward rollers into the pressing space through the introduction gap limited by two winding rollers and is gripped there by the winding rollers and by the finished bale itself, so that the bale, in interaction with the winding rollers, itself draws off from the supply roll the web length necessary for looping round the bale, the drawing-forward rollers corotating in a non-driven manner. Their revolutions are detected by a counter which can be preset and which, after a specific number of revolutions of the drawing-forward rollers have been reached, initiates the independent severance of the web by means of a knife and the automatic ejection of the bale from the press.
