摘要:
A method for operating a hybrid drive, developed as a parallel hybrid, and having a drive train, especially for a motor vehicle, having at least one internal combustion engine and at least one electrical machine device or a hydraulic machine device, a separating clutch being situated between the internal combustion engine and the electrical or hydraulic machine device and, as seen in the drive direction, the electrical or the hydraulic machine device is postconnected to the internal combustion engine, the separating clutch being separated in the overrun condition if a specifiable drag torque is able to be absorbed by the electrical or the hydraulic machine device.
摘要:
In a method for operating a communication system having a plurality of nodes which have access to a shared channel, a transmission process for transmitting a message via the channel is monitored for bit errors, and when a bit error occurs, a signaling message is transmitted via the channel in order to signal the bit error. In order to allow communications processes between the nodes to be controlled as a function of a bit error rate of the channel, a signaling rate of the signaling messages is measured and a bit error rate of the channel is determined as a function of the signaling rate.
摘要:
The present invention comprises a wheel assembly for use on a tower of an irrigation system. The wheel assembly comprises a generally cylindrical wheel having a hub, one or more spokes and a rim to which a plurality of non-pneumatic tire sections are mounted to encircle and effectively cover the circumferential outwardly facing surface of the rim. The tire segments are typically solid and comprised of a resilient polymeric material such as polyurethane.
摘要:
A pharmacologically active composition which is suitable for use in palliative cancer therapy and as an agent having a muscle-relaxing and/or analgetic effect in neurological diseases. Said composition contains at least 80 wt. %, preferbly 90 wt. %, tetrahydrocannabinol (THC) an cannabidiol (CBD), in relation to the overall weight of cannabinoids present therein. The weight ratio of THC to CBD=75:25-20:80, preferably 3:1-1:2, an especially 2:1. Said composition can be used for the production of pharmacologically effective agents which can be used in palliative cancer therapy and in the treatment of neurological disease.
摘要:
Ethylene-alkyne copolymers and ethylene-alkyne-alkene terpolymers. The copolymers and terpolymers have a number-average molecular weight, determined by vapor phase osmometry, of from 500 to 500,000 and contain, as copolymerized units,(A) from 70 to 99 percent by weight of ethylene and(B) an acetylenically unsaturated compound of the formula (I)H--C.tbd.C--R.sup.1 Iwhere R.sup.1 is (OCH.sub.2 CH.sub.2).sub.n H or CH.sub.2 -R.sup.2, n is 1-20, R.sup.2 is -OH, -OCOR.sup.3 or -COOR.sup.3 and R.sup.3 is straight-chain or branched C.sub.1 -C.sub.10 -alkyl. The terpolymers contain, as copolymerized units, from 50 to 99 percent by weight of (A), from 0.5 to 30 percent by weight of (B) and, in addition, (C) from 0.5 to 49.5 percent by weight of an olefinically unsaturated ester of the formula (II) ##STR1## where R.sup.4 is H or CH.sub.3, R.sup.5 is -OOC-R.sup.6 or -COOR.sup.6 and R.sup.6 is straight-chain or branched C.sub.1 -C.sub.10 -alkyl. The copolymers and terpolymers are prepared in a continuous or batchwise polymerixation system at from 150.degree. to 350.degree. C. under a pressure of from 500 to 3,000 bar in the presence of from 200 to 4,000 mole ppm, based on monomers, of an organic peroxide which decomposes into free radicals. The copolymers and terpolymers can be used as additives to petroleum distillates.
摘要:
A thread forming screws including opposite flanks connecting the screw crest region with the screw root region and tapering outwardly toward the root region, with each flank being formed of outer and inner flank sections tapering toward the root sections at different angles, and with the crest region being formed of a first region section (8) extending parallel to a central axis of the screw and a second, inclination region section (7) inclined toward the root region (5) in a direction opposite a setting direction (S) at an angle of from about 10° to about 45°.
摘要:
A mobile generator for generating a direct voltage for a tool supplied with direct current includes an alternating-voltage generator (1), an electronic control unit (3), a rectifier unit (2), which has a direct-voltage output (6) with live conductors (9, 10) for connecting the tool (11), and a protective device (14). The protective device is between the live conductors (9, 10) and a protective potential (18), especially ground or a protective wire. The protective device (14) has an insulating spark gap (15) responding in the case of an error with a defined response voltage (UT) for grounding the live conductors (9, 10).
摘要:
An interactive water slide includes a plurality of light and sound sources synchronized with a theme chosen by the rider, the lighting and sound changes as the rider travels down the slide. Images are projected onto a screens of water that block the path of the rider and as the rider travels down the slide the rider must go through these projected images.
