Title: Digital local communications system with the logical structure of a loop
Inventor: SCHROECK WERNER DR RER NAT
IPC: H04L12/407
Filed: 1984-04-07
Abstract: For a digital local communications system in the form of a bus with the logical structure of a loop in which the stations connected to terminal devices are in each case connected to a transmitting line and to a receiving line running in parallel with the former, with data flow directed in the same or in the opposite direction, and transmit their data as data packets provided with a priority flag, the stations feeding their data packets into the transmitting line only, and in which the data packets are transmitted at one point in the network from the transmitting line to the receiving line, it is proposed to allocate a request flag to each data packet in addition to the priority flag. The stations can feed their data packets into the transmitting line even if data packets with a lower priority than the priority of the data packet to be transmitted arrive on the transmitting line. In equal-priority incoming data packets, the request bit of the external data packet is set to "1" by the station wishing to transmit. If heavy data traffic occurs on the receiving line, the transmission protocol causes the data packets to pass through, extensively arranged according to priority, high-priority data packets can be transmitted immediately and access is provided to the data medium in the appropriate order with maximum utilisation of the transmission medium.

Title: Operating procedure for an air/water heat pump
Inventor: BAUMGAERTNER MANFRED DR
IPC: F24D19/10
Filed: 1984-08-09
Abstract: The invention relates to an operating procedure for an air/water heat pump 1 having two compressors, the air/water heat pump 1 firstly carrying out the hot water preparation in a priority sequence in the event of a corresponding demand and then carrying out the space heating. The ambient temperature tA is compared with a first limiting temperature t1. During hot water preparation, in the event of an ambient temperature tA below said first limiting temperature tGl, both compressors are taken into operation, and only one compressor is taken into operation above said first limiting temperature tGl. Consequently, the output of the air/water heat pump is matched to the output of a heat exchanger used for hot water preparation, so that in the event of low ambient temperatures the heating up times for the hot water are shortened by comparison with the general one-compressor operation. Consequently, in the event of low ambient temperatures tA the room temperature decreases less during hot water preparation. <IMAGE>

Title: Adjustable and re-adjustable, self-centring and self-locking internal bottom ball bearing unit
Inventor: HOFFMANN URSULA
IPC: B62K19/34
Filed: 1984-09-19
Abstract: Re-adjustable and adjustable, self-centring and self-locking internal bottom bracket ball bearing unit, especially for use in vehicles with two or more wheels whose drives are muscular force and/or auxiliary motors. Previously used complete internal bottom bracket ball bearings are based on the use of deep groove ball bearings or their systems and therefore require axles - and of course ball bearings or ball bearing races - specially manufactured for them. The construction principle does not permit re-adjustment when required. In the internal bottom bracket ball bearing unit presented, both a previously used bottom bracket ball bearing axle and commercially available ball bearing races are used. By means of an adjustment ring with a thread which can only be used in one direction, the bearing play can be adjusted and re-adjusted as required and is at the same time also secured against loosening. By virtue of overlapping diameters of the bottom bracket ball bearing unit and of the installation housing, and by virtue of the slip phases provided, centring and form fitting matched to the housing occurs during assembly so that the bottom bracket ball bearing unit is both attached centrally and secured against rotation. By maintaining a smaller diameter in the central area of the internal bottom bracket ball bearing unit, space is provided which permits cables to be led through the housing of the bottom bracket ball bearing.

Title: Fixed addition-value circuit in decimal code
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1985-03-08
Abstract: In the fixed addition-value circuit according to the subject matter of the invention, the odd summands 1 and 3 and 5 and 7 and 9 are processed decremented by the number 1 in both input ranges and thus the number of required sum-and circuits is decreased to 25. The wrong result numbers are corrected by means of two up-shifting circuits which are combined with a linear circuit and are arranged at the end of this fixed addition-value circuit. The first up-shifting circuit is a two-up-shifting circuit which raises the number present at its inputs by the number 2 in the case of shift activation. The second up-shifting circuit is a one-up-shifting circuit which raises the number present at its inputs by the number 1 in the case of shift activation. These shift circuits are controlled by means of a binary half-adder 20. <IMAGE>
