Title: High-voltage switch
Inventor: ACKERMANN ULRICH DIPL PHYS DR
IPC: H01H1/38
Filed: 1987-10-30
Abstract: The high-voltage switch has a rated current path, which contains two rated current contacts (5, 7), and an extinguishing current path, which is arranged parallel thereto and contains two consumable contacts (4, 6). A first (5) of the two rated current contacts is formed by at least one contact finger (10) which is mounted in a sprung manner in a contact support (9) and is supported in the switched-on position on a contact surface (19) of the contact support (9) at one end and on a second (7) of the two rated current contacts at the other end. This high-voltage switch is intended to be constructed in such a way that its contact arrangement does not need any maintenance even after disconnecting large currents many times. This is a result of the at least one contact finger (10) being part of a guide element (for example a mounting for rotational movement with the insulating part 20) which, during switching off, removes the at least one contact finger (10) from the contact surface (19) of the first rated current contact (5). At the same time, an arc (22) is formed which, connected in series with a further arc (21) formed during switching off, ensures that the current to be disconnected is reliably commutated from the rated current path to the extinguishing current path. <IMAGE>

Title: Method and device for soldering
Inventor: HOHNERLEIN ERNST
IPC: B23K1/008
Filed: 1987-11-05
Abstract: The invention relates to a method for soldering, particularly for mounting electronic components on printed-circuit boards or printed circuits, the connection elements of the components already having been provided with a layer of tin-lead solder (tinman's solder) and the areas to be soldered being heated by thermal radiation. The crux of the invention is that the heating, in a first phase, takes place gradually by means of radiant heat to 180@C, i.e. the melting point of the tin-lead solder, that then a further short-term heating takes place until the eutectic of the tin-lead solder is reached, i.e. from 225@C to 230@C, heated nitrogen having a temperature from 250@C to 350@C being added additionally in the region of the soldering section, which nitrogen then flows in one direction for heating the newly arriving printed circuit boards, and in the advance (feed-forward) direction in order to prevent secondary oxidation.

Patent DE-3740027-A1 (DE)
Title: Middle condenser
Inventor: HOLZ HANS-JOSEF
IPC: D01H5/72
Filed: 1987-11-26
Abstract: Middle condenser for rovings fed to the drawframe of a spinning machine Known middle condensers are designed either for stationary operation and for feeding two rovings fed to the draw frame in parallel or for traversing operation during the feed of only one roving. In order to change over from the processing of two rovings to the processing of one roving, and vice versa, it is necessary to dismount the middle condensor, thus leading to relatively long standstill times of the spinning machine for the conversion. The invention is intended to remedy this. In the novel middle condenser, there is provided in the middle between the two roving-guide channels for the feed of parallel rovings a third roving-guide channel which is used when the middle condenser moved in a traversing manner is used for the feed of only one roving to be processed. The standstill times for the conversion of the spinning machine from one operating mode to the other are thereby markedly reduced, because only the rovings to be processed have to be threaded in, whereas there is no need to exchange the middle condensers.

Patent DE-3816273-A1 (DE)
Inventor: FEUERHERM HARALD
IPC: B29C48/09
Filed: 1988-05-12
Abstract: In a method for producing hollow articles from thermoplastic material, a tube-like preform is formed by discharge from a die gap of an extrusion head and inflated in a blow mould. Furthermore, the position of the preform with respect to the blow mould is adjusted by open-loop and/or closed-loop control and finally the flash produced by the blow mould is separated from the article once it has left the blow mould. 
<??>In order on the one hand to achieve a correct position of the preform in critical cross-sectional areas with respect to the blow mould and on the other hand to achieve a correct weight of the hollow article to be produced, it is proposed that for controlling the position of the preform in accumulator head operation the weight of the cut-off bottom flash and/or the net weight of the hollow article be measured and, depending on a weight discrepancy in comparison with a set value, that the die gap be altered, and in continuous extruder head operation that either the net weight of the hollow article and the weight of the bottom flash be measured and compared with set values or the net weight of the hollow article and the position of marks in relation to particularly critical cross-sectional areas be compared with predetermined set values and the positional control derived therefrom.

Title: Multi-step process for heat treatment and heat exchanger
Inventor: BECKMANN GEORG DIPL ING DR
IPC: F26B3/22
Filed: 1988-07-08
Abstract: The invention relates to a process for heat treatment of granular solids, in particular of bulk materials becoming granular, as well as sludge, in which process advantageously there is no intermediate heat transfer medium used in the heat exchanger 1. The heat exchanger 1 is constructed as a vibratory apparatus with substantially mutually parallel partial channels 2, 3 and functions as a recuperative heat exchanger, hot and cold bulk material alternately flowing through the partial channels arranged beside one another. Particular advantages ensue if the recuperative heat exchanger has concentric annular channels 2, 3, in which the discharge location 6, 7 is arranged beside the feed location 4, 5 and in particular the feed of each second partial channel 2 and 3, respectively, takes place offset by 180@ via the ring, so that both the feed and the discharge of each of the two bulk-material streams takes place on in each case one side of the vibratory apparatus 1. An advantageous construction ensues if the annular vibratory heat exchanger 1 is arranged annularly around the apparatus 10 for finishing treatment. <IMAGE>

Title: Working screw for mincing machines
Inventor: HAACK EBERHARD DR ING
IPC: B02C18/30
Filed: 1988-07-13
Abstract: The invention relates to a working screw for mincing machines and comminution machines functioning according to the mincing-machine principle and is used in all processing plants of the meat industry. Using the present invention, an improvement in performance with simultaneous blocking of the material being processed so as to prevent return flow is to be achieved. This occurs in such a manner that the working screw has a geometrical configuration which opposes the return-flow conditions, and has so-called return-flow barriers which result from the shape of the working screw itself or in the form of hindering elements which are arranged on the flanks of the screw turns of the working screw. The formation of the return-flow barriers is achieved in that the working screw has a reduction in diameter of the screw core, as seen in the direction of the cutting set, or the flank width of the central screw turns of the working screw is increased.

Title: Method for increasing the resolution of an A/D converter
Inventor: DIEWALD HORST
IPC: H03M1/20
Filed: 1988-07-29
Abstract: A method for increasing the resolution of an A/D converter is described which converts an analog input signal value into a corresponding digital output signal value. When a conversion process is carried out, a comparison between the analog value to be converted and an analog signal corresponding to a predetermined digital signal and passing through a predetermined range of values in the course of a conversion cycle is carried out in the converter. When the method is used, a number of conversion cycles are carried out and the digital values obtained in each case are stored. In addition, the frequencies of occurrence of the individual digital values are stored. The curve of the statistical distribution of the stored digital values is calculated using the stored frequencies. The digital value corresponding to the peak of the calculated curve is taken as the digital output value to be generated.
