Title: Digital wave filter
Inventor: EYSSELE HELMUT DIPL ING
IPC: H03H17/02
Filed: 1982-12-15
Abstract: In digital wave filters having an extremely narrow bandwidth, multiplier coefficients occur, the representation of which requires a long coefficient word length. According to the invention, the disadvantageously long coefficient word length is shortened by the fact that at least one circuit section necessary for the filtering function is in each case replaced by a combination of circuit sections, the multiplier coefficients of which are selected in such a manner that the overall filter function is not changed.

Title: Process for the preparation of dodecylguanidine acetate
Inventor: SCHWIENBACHER HELMUT DR
IPC: C07C277/08
Filed: 1982-12-24
Abstract: The invention relates to a process for the preparation of dodecylguanidine acetate by reacting dodecylamine with cyanamide and acetic acid in an inert solvent and is characterised in that the dodecylguanidine remaining in the waste liquor after removal of the reaction product and unreacted dodecylamine are selectively precipitated. By recycling the dodecylguanidine and dodecylamine isolated from the waste liquor into the mixture of the starting materials, a dodecylguanidine yield of >/= 95 %, based on the dodecylamine employed, can be achieved. By means of the process according to the invention, the concentration of dodecylguanidine acetate and dodecylamine in the waste liquor can also be reduced so much that the waste liquor can be passed, without further treatment, to a biological effluent treatment plant for the degradation of cyanamide and the other byproducts.

Patent DE-3322089-A1 (DE)
Title: Device for feeding auxiliary air into the intake port of an internal-combustion engine
IPC: F02M23/09
Filed: 1983-06-20
Abstract: The invention relates to a device for feeding auxiliary air into the intake port of an internal combustion engine downstream of the throttle valve, viewed in the direction of flow. This feed is performed by means of a distributor, which ensures an especially intensive swirling and mixing of the intake mixture with the auxiliary air. The amount of auxiliary air fed in at any time has hitherto been predetermined by a governor which, viewed in the direction of flow was connected to the intake port downstream of the throttle valve. By contrast it is proposed that this governor according to the invention be now connected upstream of the throttle valve. If the amount of auxiliary air is predetermined as a function of the vacuum prevailing there a significant reduction of the pollutants contained in the exhaust gases and also of the fuel consumption can be obtained.

Title: Method and arrangement for pressing the core parts of Roebel rods and two-layer formed coils
Inventor: SPERLING KLAUS ING GRAD
IPC: H02K15/10
Filed: 1983-08-19
Abstract: During the pressing to size of prepreg-insulated core parts of Roebel rods and two-layer formed coils before curing in a heating press, it is intended to prevent an air layer enclosed during winding also being pressed in and excess bonding resin being displaced in an uncontrolled and undirected manner when the press is being closed and in this case, in particular, during application of the compression pressure, by means of lateral compression plates (2, 2'), onto the broad sides of a conductor rod (6) of rectangular cross-section. To this end, the lateral compression plates (2, 2') are prebent in a resiliently elastic manner over their length towards the conductor rod (6). The pressing to size then takes place initially by applying a compression pressure onto the narrow sides of the core part of the conductor rod (6) until a predetermined height dimension is reached, and, subsequently thereto, by applying a pressure to the broad sides which initially (as a consequence of the prebent lateral compression plates (2, 2') acts only over the height of the centre of the broad sides and then builds up continuously towards the longitudinal ends of the broad sides until the core part is also compressed to a predetermined thickness dimension. <IMAGE>

Title: Intermediate element for relatively high strength connecting elements
Inventor: ROEHRICH DIETER DR ING
IPC: F16B43/00
Filed: 1984-09-26
Abstract: The invention relates to an intermediate element which is used for connecting or bracing components of low strength to connecting elements having higher strength and which is constructed in terms of its dimensions and strength properties such that it allows the load capacity of the supporting capability of the higher strength connecting elements to be used fully, results in the elimination of stress-dependent flow processes, and prevents destruction of the component surface resulting from a rotational movement of the connecting elements caused by tightening. The use of the intermediate element makes it possible to reduce both the number of the connecting elements, or their cross-section, and to reduce the cross-sectional dimensions of the components to be connected. The essence of the invention is the allocation of the dimensions and of the strength properties of the intermediate element to the maximum possible clamping force of the connecting elements, to the strength properties of the components to be connected and to the deformation angle of the intermediate element, as a result of which the intended object is achieved with minimum dimensions of the intermediate element. <IMAGE>
