Patent DE-3829397-A1 (DE)
Inventor: ALBRECHT THOMAS
IPC: E03F5/02
Filed: 1988-08-30
Abstract: The invention relates to a drain manhole comprising a preferably corrugated pipe (1), in the wall of which openings are formed for connection to piping (36) and at the lower part of which a weight is disposed for increasing the stability. According to the invention, the weight takes the form of a ballast arrangement which is separated from the pipe (1) and can be attached to the latter. The said ballast arrangement may take the form of a chamber (3) which can be filled with liquid or bulkable solid ballast material and is formed on or can be attached to the underside of the pipe. The ballast material is preferably a bulk material and/or a liquid. Consequently, the time-consuming filling with concrete, which was necessary hitherto in the production of drain manholes, is eliminated and the transportation of the pipes is easier as they do not contain, as hitherto, a concrete weight from the very outset. <IMAGE>

Title: Power diode
Inventor: MOURICK PAUL
IPC: H01L29/861
Filed: 1988-09-14
Abstract: The reverse current in a power diode generates switching power losses in the diode. If the reverse current has a high peak, the diode can be destroyed. The reverse current peak and the quantity of charge carriers can be reduced while approximately maintaining the forward voltage constant by providing that the outer zones (6, 7) adjoining the weakly doped mid-section (1) of a diode have a thickness of less than 1  mu m and are doped by implanted ions with a dose of between 1 . 10<12> and 1 . 10<15> cm<-2>. <IMAGE>

Title: Process for purifying flue gases
Inventor: SCHENK JUERGEN DR RER NAT
IPC: C02F11/12
Filed: 1989-01-17
Abstract: The invention relates to a process for purifying flue gases based on wet scrubbing with calcium carbonate or calcium hydrogen carbonate which can be chiefly used for relatively small furnaces and boiler units. The aim of the invention is to achieve a marked reduction of the discharges of dust and sulphur dioxide, in particular in the case of fuels having high pollutant contents, such as raw brown coal, an economic operation and high reliability having to be achieved. According to the invention, the object is achieved by separating off the coarse dust fractions before wet scrubbing and feeding the same to a post-reaction vessel in which the thin sludge taken off from the pulp circulation tank is mixed, with stirring, with the coarse fractions, during which the fly ash is leached and a sludge which is easy to treat in the following separation apparatus is produced.
Patent DE-3901589-A1 (DE)
Inventor: WEIGL ANDREAS
IPC: H04L12/40
Filed: 1989-01-20
Abstract: Coupling of a local network subscriber comprising at least one emitter and/or receiver part, in particular a motor vehicle, to a data bus with two bus lines, characterized in that the bus lines (B0, B1) are associated with RC switch elements (R5, C1; C2) connected to a resistance network. As a result of the co-operation of the capacitors with the resistors of the resistance network, potentials arise at the input terminals (RXo, RX1) of the receiver part of the subscriber (10), which ensure that the data present on the data bus are identified even in the event of a short circuit of one of the bus lines to earth, to the battery voltage or to the other bus lines, or if one of the lines is disconnected.

Patent DE-3909584-A1 (DE)
Title: Doorlock with automatic intrusion protection by blocking the locking device
Inventor: DROSTE DIETER
IPC: E05B45/06
Filed: 1989-03-23
Abstract: The invention relates to the protection of a doorlock, in which, if the lock cylinder or the cylinder plug is broken out, torn out or destroyed, a mechanism blocks the locking device of the lock in such a way that it is no longer possible to open the door from outside via the lock. One solution is to cover the locking device so that break-in tools, such as a picklock, can no longer engage into the locking mechanism and therefore can no longer release the bolt. This device can also prevent the bolt from being pushed back. Figure 1 shows a mechanical solution by means of a spring. Another solution mechanism provides for the direct blockage of the bolt, so that the latter can no longer be moved. After the lock cylinder has been destroyed, a door can be opened again by an authorised person via an unlocking mechanism. As a result of this cylinder protection, this lock, together with a suitable electronically monitored bolt contact accommodated in the stationary part of the door, can be used as a block lock for alarm systems. <IMAGE>

Title: Chimney fitted with extension and fan - incorporates collar to reduce noise emitted by fan unit
IPC: F23L17/00
Filed: 1990-01-12
Abstract: The chimney (5) is fitted with an extension (1) which has a fan (2) mounted above its upper end. The fan (2) is so mounted that there is a narroe gap (10) between it and the extension (1). The extension (1) is fitted with a collar (3) of L-shaped cross-section which extends around the perimeter of the chimney extension. This collar (3) is aligned with the gap (10) and its height is greater than the width of the gap (10). The collar reduces the noise emitted from the chimney when the fan is operating. The noise may be further reduced by covering the collar with a layer of sound reflecting or absorbing material.
