Title: Parallel vice with two clamping ranges
Inventor: KRAUSSE MANFRED DIPL ING
IPC: B25B1/24
Filed: 1986-06-02
Abstract: The parallel vice with two clamping ranges is usable in the craft and do-it-yourself sector. The object of the invention is to provide a parallel vice for the craft and do-it-yourself sector which is universally usable and possesses a short and long clamping range for horizontal and vertical clamping. According to the invention, this is achieved by the fact that two guide columns are firmly screwed in and a spindle is rotatably mounted in the movable clamping jaw. The fixed clamping jaw has three holes for the reception of the guide columns. In this arrangement, two holes are occupied in each case by the guide columns. For clamping in the short range, the two lower guide holes are used. For clamping in the long range, the movable clamping jaw is unscrewed from the fixed clamping jaw, pivoted through 90 DEG  and inserted by the guide columns into the upper and the underlying hole again. An additional long-range clamping jaw, which is independently fixed to the work table in accordance with the length of the workpiece to be clamped in, serves as a fixed clamping jaw in the long clamping range of the vice. In this arrangement, both the long-range clamping jaw and the clamping jaw now pivoted through 90 DEG  are designed so that a clamping height of at least 10 mm is guaranteed. Consequently, clamping the workpiece in the horizontal and vertical plane is possible without further alteration of the clamping device.

Title: Process, in particular for producing a heat exchanger, and a heat exchanger
Inventor: GEMEINHARDT HERMANN
IPC: B29C65/14
Filed: 1986-10-24
Abstract: Process for the permanent fastening of the end or ends of at least one rod, consisting at least partially of thermoplastic material and having in each case at least one continuous cavity, in at least one opening of a supporting plate encompassing at least one rod. In this process, for its fastening, each rod is positioned in openings of the supporting plate provided for it, each rod cavity having a hydraulic diameter which corresponds to at least 10% of the smallest outer cross-sectional dimension of the rod, and the rod walls may have pores which make up at most 20% of the wall volume. The said process is intended in particular for producing heat exchangers and is characterised in that the rods with the supporting plate are positioned in such a way that the ends of the rods are arranged substantially vertically upwards and the supporting plate is arranged substantially horizontally, in that then heat is supplied from above to the rod ends to such an extent that the rod ends soften at least partially and the outer walls of the rod end expand in such a way that they come to bear against the walls of the supporting plate openings and are adhesively bonded or fused with the latter. <IMAGE>

Title: Method and device for the inclusion of additive and multiplicative correction variables in a continuous fuel feed system
Inventor: JUNDT WERNER DIPL ING
IPC: F02D41/14
Filed: 1986-12-12
Abstract: In the case of a method and a device for the inclusion of both additive and multiplicative correction variables in a learning system continuously feeding fuel to an internal combustion engine, it is proposed to carry out the lambda averaging separately on two averaging devices for distinctly differing operating states of the internal combustion engine and to apply a reduction factor to the output of one of the averaging devices so that the influence of its learned value is increasingly reduced with a varying operating variable of the internal combustion engine, resulting in an additive correction. This additive correction serves for compensation of an offset error in the original straight line  lambda  = 1, traceable to air leakage, and represents a flow correction in the actuator current for a valve continuously injecting fuel. <IMAGE>

Title: Heating device, in particular supplementary heating device for vehicles
Inventor: PANICK KARL
IPC: F23M20/00
Filed: 1987-04-22
Abstract: According to the invention, a heating device, in particular a supplementary heating device for vehicles, is provided, in which a sound damper is provided in the combustion chamber or the combustion chamber itself is constructed as a sound damper. The sound damper can in this case damp the noise of combustion and the noises of the combustion gases by absorption and/or by reflection. In addition, the sound damper can also be designed in such a way that it simultaneously cleans the combustion gases, for example by catalytic post-combustion and/or by filtering out soot particles if the heating device is operated with diesel fuel as liquid fuel. However, since the sound damper in the hot zone is not arranged in the flame area of the combustion chamber, it is not directly affected by the high flame temperatures but, nevertheless, self-cleaning of the sound damper is brought about by the relatively high temperatures so that it can operate reliably and effectively over relatively long operating times.
