Abstract: A clock bus system fabricated on an integrated circuit for distributing a train of clock pulses to circuit elements on the integrated circuit. An input terminal is connected to receive a train of clock pulses. All of the circuit elements are circumscribed by a clock bus which is also coupled to each of the circuit elements. A plurality of distribution legs which include clock bus drivers are coupled to the input terminal by conductors and provide the train of clock pulses to the clock bus at spaced-apart locations. The distribution legs coupled to the input terminal by shorter conductors include delay elements for delaying the clock pulse train by time periods corresponding to the delay inherent in longer conductors. The clock pulse trains provided to the clock bus by the distribution legs are thereby synchronized with respect to each other.

Abstract: At least one end of a rucksack frame member (22 or 23) may be secured to a fabric sack (21) by being accommodated in a passageway defined by a raised portion (12) of a fastening device (10), a further portion (11) of which is fixed to the sack (21). Movement of the frame member end through the passageway is limited by abutment against a stop member in the form of a resilient flange (13) projecting into the passageway. However, during assembly of the rucksack in the case where the frame member is a bar (22 or 23), it can be inserted right through the passageway, past the stop member (13), the latter springing back to block the passageway once the trailing end of the bar has passed thereby.

Cooling air is introduced downwardly into the heat exchanger (10) from duct (16) and is diverted horizontally by the hypotenuse of the cooling fins (18, 20). The cooling air leaves the heat exchanger (19) in mutually opposite directions through the passageways (30) formed between adjacent fins in each set of fins. The heat exchanger (10) is particularly useful as a heat sink for use with electronic chips (12). 
     Several other embodiments are described.

Abstract: For the temperature compensation of electric networks having an adjustable transfer factor, a quantity which contains an information item on a desired transfer factor is multiplicatively combined with a signal which is approximately proportional to the common temperature of the elements of the electric network. This temperature compensation is suitable for networks whose transfer factor is approximately monotonically dependent on the temperature. Using the method according to the invention, the temperature compensation is also ensured over a large adjustment range of the transfer factor. <IMAGE>

Abstract: In the knitting machine with a thread-changing device with knotter, in which a thread is guided from the knotter (10) via a thread storage device (30) to a thread processing station (16), the thread length between the knotter and the thread processing station is always kept the same, so that the control device (20) has fixed data for this length available for the purpose of triggering the formation of a knot during the thread change. Moreover, the drive movement of the knitting machine (17) is monitored by means of a path transmitter (22) which, independently of the needle division of a needle bed, supplies for each unit of path length a predetermined number of pulses which are evaluated as clock pulses in the control device (20). The construction of the control device can be simplified as a result of these measures.
