Title: Circuit arrangement of a voltage supply for directly heating polycrystalline silicon rods during their production
Inventor: MUELLER REINHOLD ING
IPC: C01B33/035
Filed: 1985-09-28
Granted: 1987-02-26
Abstract: In a circuit arrangement for supplying voltage for the production of polycrystalline silicon rods to which an ignition voltage for self-heating is in each case applied in two pairs (U1, U2) electrically connected in series from an alternating voltage source (E), it is to be achieved that the voltage present across the pairs is increased without changing the alternating voltage source (E). For this purpose, a turn-off type semiconductor element (T1, T2) is connected in parallel with the pair (U1, U2). The semiconductor element (T1) allocated to one pair (U1) is polarised in the opposite direction to the semiconductor element (T2) allocated to the other pair (U2). For each half period, the alternating voltage provided by the alternating voltage source (E) is applied via the oppositely connected semiconductor elements (T1, T2), which are permanently ignited by means of igniting devices (Z1, Z2), in full amplitude to in each case one of the pairs (U1, U2). The voltage is thus higher by a value of 2<1/2> times than when the pairs (U1, U2) are purely connected in series. <IMAGE>

Title: Towing coupling which can be locked in the open position
Inventor: BUTHE THEO DIPL-ING
IPC: F16D1/10
Filed: 1985-10-31
Granted: 1987-05-21
Abstract: It is the object of the invention to improve the towing coupling according to the main application, which can be locked in the open position, such that it can be switched reliably from the locked open position into the locking position even where there are only two locking elements for axial retention, and to do this irrespective of the angular position of the slot in the slotted spring ring, and to ensure ease of assembly. This object is achieved, according to the invention, by virtue of the fact that the ends (126, 127) of the slotted spring ring (103) on either side of the slot (115) are connected to one another by means of a bridge (122) which can be moved in the circumferential direction in at least one of the two ends (126, 127), such that their motion is conformal in the radial direction. <IMAGE>

Granted: 1987-11-19
Abstract: A method and an apparatus are described for the stress testing of glass containers (10) which are arranged hanging, by impulse action on the bottom (14) of the container through the adjustable action of force on an impacting rod (12) resting on the bottom (14) of the container. For the action of the force, an adjustable source of energy (26) is used which may comprise an eccentric, an ultrasonic transmitter (26b), a magnetic actuating drive or the like, which acts on the end (18) of the rod (12), resting on the bottom of the container, remote from the bottom (14) of the container. The shaking exerted on the glass container during subsequent filling can be simulated by the action of the force which is adjustable in duration and/or amplitude, so that glass containers suspected of breakage can be eliminated by the stress test before being filled. The action of force can be proportioned in a simple manner so that optimum test vibration values can easily be adjusted.

Title: Apparatus for joining elements resting flat upon one another, for example metal sheets, by the joggling method
Inventor: SINGH SUMANJIT DIPL-ING
IPC: B21D39/03
Filed: 1987-01-23
Granted: 1988-03-17
Abstract: The invention relates to an apparatus for joining elements resting flat upon one another, for example metal sheets (1, 2) by the joggling method (joining by bending without cutting), one section of an upper sheet (1) being pushed through a lower sheet to a position behind that side of the lower sheet which faces away from the upper sheet (1) by the interaction of a punch (3) and a die (4) and the two sheets (1, 2) being flow-pressed transversely to the push-through direction. In this process, they are compressed and spread out between the mating pressure surfaces of the punch (3) and the die (4) by a pressure directed perpendicular to their surface. A joint produced in this way is of high quality if the deformed portion of the upper sheet (1) facing the punch (3) exhibits a greater flow than the deformed portion of the lower sheet (2) facing the die (4), thus enabling a relatively large overlap and hence relatively large area of support to be achieved. In order consistently to achieve flow behaviour of this kind, the invention provides that the contact surfaces (7, 15) of the punch (3) and the anvil (10) of the die (4) facing the sheets (1, 2) to be joined each have different surface roughnesses, the anvil surface always having a greater roughness than the punch surface (7). <IMAGE>

Title: Method for determining the type of encoding to selected for the encoding of at least two signals
Inventor: HERRE JUERGEN DIPL ING
IPC: H03M7/30
Filed: 1993-09-15
Granted: 1994-11-10
Abstract: In the case of encoding a plurality of signals which are not independent of one another, the suitable type of encoding is selected as a function of a degree of similarity. According to one aspect of the invention, the degree of similarity is determined by initially encoding one of the signals according to the intensity stereo method and then decoding it, in order to create a signal having an encoding error, whereupon the latter signal and the associated non-encoded signal are transformed into the frequency domain. In the frequency domain, selection or evaluation of the actually audible spectral components both of the signal which has the encoding error and of the associated signal which does not have the encoding error is performed with the use of a monitoring threshold which is determined by psychoacoustic calculation. In the case of a high degree of similarity, intensity stereo encoding is performed, whereas otherwise the channels are encoded separately.

Title: Fastening device for a pneumatic compression spring
Inventor: KURZYNSKY PETER
IPC: E05F1/12
Filed: 1993-12-04
Granted: 1995-02-02
Abstract: It is known to pivotably secure a pneumatic compression spring at one end by the end provided with a bolt being inserted into a mounting fixture and then by the pneumatic compression spring being pivoted by 90 DEG  transversely to its longitudinal axis into its functional position. Furthermore, fastening devices are known in which the pneumatic compression spring is connected in a push-in manner to a mounting arrangement roughly parallel to its longitudinal direction in the fitted position, the mounting arrangements consisting of a relatively large number of parts and being prone to wear and failure in operation. The novel fastening device for pivotably securing an end (2) of a pneumatic compression spring (1) to a support part (3) comprises a bolt (5), fixed to the end of the pneumatic compression spring so as to run transversely to the longitudinal axis (4) of the pneumatic compression spring, as well as a mounting part (6) on the support-part side and a mounting part (9) on the pneumatic-compression-spring side interacting with the mounting part (6), the mounting part (6) on the support-part side having a through-opening (7) in such a way that the bolt can be pushed through only in a position turned about its longitudinal axis preferably by about 90 DEG  relative to the functional position of the pneumatic compression spring, the bolt, in the functional position of the pneumatic compression spring, interacting with a rear stop surface (8) of the mounting part (6) on the support-part side. Use, for example, for pivotably securing a pneumatic compression spring to a vehicle tailgate. <IMAGE>

Title: Arrangement for obtaining heat energy
Inventor: HESSE WINFRIED
IPC: F24S90/00
Filed: 1994-02-24
Granted: 1994-09-29
Abstract: In the generation of heat for heating and hot water, the effect of heat pumps is used, in which a given quantity of energy supplied transports a multiple of this energy from a low to a higher level. The power factor which can be achieved in this process depends on the temperature difference between the low and the high level. In the arrangement with a heat pump chosen here, the lower temperature level is limited to 0 DEG C, a water reserve being at least partly frozen. If energy is extracted from a water reserve by means of pipelines, then the water reserve freezes in a block, the ice being formed being deposited as an insulating layer around the pipelines and consequently making the heat transfer more difficult. According to the invention, therefore, an arrangement is proposed, in which the ice formed is prevented from reducing the heat transfer at the absorber by the absorber being arranged above the water and ice formed being returned to the water reserve in the form of small pieces. <IMAGE>

Inventor: LECHNER ROBERT DIPL ING
IPC: H04Q11/04
Filed: 1994-12-12
Granted: 1995-10-19
Abstract: The present invention relates to a method for the multiple access use of bit-transparent ISDN links by any subscribers and a device for carrying out the method. Normally in ISDN (Integrated Services Digital Network), a dial connection is established individually between subscribers, said connection carrying 64 kbps even over long-distances. That bit rate would be sufficient for the simultaneous transmission of several digitally coded voice signals. In local areas (LSA), devices such as ISDN private branch exchanges are connected to ISDN local exchanges for the purpose of carrying out the method. These devices form what is called an ISDN Link Sharing System (ILSS), reflecting their function. The ILSS elements are connected via bit-transparent dedicated lines which carry the basic traffic. For peak traffic, bit-transparent dial connections are established. All these bit-transparent links are used simultaneously for several links thanks to the use of signal processors to reduce the signal bit rate. Signalling which is also used for forwarding dialling data is exchanged between the ILSS devices, which capture charge data and carry out authorisation checks. The ILSS devices can also be connected between different user networks and indirectly formed into a network via network nodes.
