Filed: 1986-02-05
Abstract: The invention relates to a heating element for heaters which has in each case one layer of interactive material (6) in order to avoid heat-loss layers between a PTC thermistor element (1) and electrode plates (3). The two electrode plates (3) can be mounted directly on the PTC element, by means of methods which are known per se, such as sintering or plasma spraying, for the same purpose. Finally, the complete element, consisting of the PTC module (1), the electrode plates (3) and (in a further refinement) an insulation layer (14) and (in a very efficient and very economic design) a heat exchanger or soldering tip (15) can be manufactured in one operation by sintering, plasma spraying or similar methods. The invention also relates to a soldering device using a heating element (10) according to the invention in the soldering tip (15), the device additionally being produced by means of insert injection-moulding methods (overmoulding methods) such that the body (16), cable kink protection sleeve (20) and internal electrical connections (17) are integrally formed from insulating and fracture-resistant material. As a result of the diametrical sizes, which are very small overall, a very thin, pin-like construction of the soldering device according to the invention can be achieved. <IMAGE>

Title: Method for automatic printing of vertical and/or horizontal lines in a word processing system
Inventor: BRANDES RONALD DIPL ING
IPC: B41J29/26
Filed: 1987-01-23
Abstract: In known word processing systems, "tab vertical line" was used to generate vertical lines. However, many entries were necessary for this, e.g. set tab, jump to tab, carriage return with line feed, etc., until a vertical line of the required length was generated. Horizontal lines were generated in an equally involved way, using the underline character. The object of the invention is to create a method of printing vertical and/or horizontal lines in a word processing system, using which perfect vertical and/or horizontal lines of arbitrary, exact length can be produced, while using smaller quantities of data to be stored in memory. This object is achieved as follows. The document to be printed is first positioned to the start point of the line to be printed, this point is then marked with a special first code function key, and its co-ordinates are stored in a start point register. The document to be printed is then positioned to the end point of the line to be printed, this point is then marked with a special second code function key, and the difference between the co-ordinates of the end point and the co-ordinates of the start point is stored in an end point register. Printing of the lines thus defined is then initiated using a third code function key. The subject of the invention sets a ... Original abstract incomplete

Patent DE-3706929-A1 (DE)
Inventor: SCHILLING HERBERT
IPC: B22D27/08
Filed: 1987-03-04
Abstract: Casting moulded metal parts (4') involves pouring molten metal into at least one pouring inlet (6) disposed within the area of the upper side of a casting mould (1), said inlet being connected with the lower area of the moulding cavity (3) by means of at least one channel (5); during said casting, the molten metal in the channel (5) is required in order to ensure that the blowhole is formed outside the casting. This may be achieved by means of an airhole of suitable dimensions, or by maintaining the casting pressure. Firstly, the molten metal within the casting mould (1) is passed through at least one pre-chamber (4) disposed below, and connected to, the moulding cavity (3). When the moulding cavity is completely full, the casting mould is swung about a horizontal axis (9) and moved from the casting station. The molten metal most recently poured in, therefore at the highest temperature on termination of the casting process, is now situated above the casting and assumes the function of the airhole. In comparison with the known process, wastage may be reduced by at least one half.
Patent DE-3707709-A1 (DE)
Title: Scaffolding frame for structural scaffoldings or the like
Inventor: ZESSLER GEORG ING GRAD
IPC: E04G7/30
Filed: 1987-03-11
Abstract: Scaffolding frames used for structural scaffoldings exhibit plug-in connections with pins fitting into the uprights or columns of the scaffolding frame in order to be able to plug such scaffolding frames together and consequently form a scaffolding. The plugged-together scaffolding frames are secured against undesired release by means of bolts or screws which are to be plugged through the columns and the pins projecting into said columns. These known arresting means are, however, not satisfactory from a technical point of view, require additional expenditure in terms of labour and time and can be forgotten, intentionally or unintentionally, during assembly of the scaffolding. The novel scaffolding frame is simple to assemble and to secure, without additional outlay, against undesired release of plugged-on scaffolding frames of the same type. In the case of said scaffolding frames, each pin has an outer end which tapers conically on one side, and at least one of the pins has, on the side opposite the tapering, a latching element which is assigned, in the other end of the column opposite the pin, a matching counter-latching element. When assembling such scaffolding frames, the scaffolding frame which is to be plugged on is plugged obliquely onto the upright pin of another scaffolding frame which has already been mounted, and it is then moved into the desired vertical position, the latching elements passing into engagement with one another of their own accord.
