Title: Fixed-value addition circuit in decimal code
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1985-04-15
Abstract: The fixed-value addition circuit according to the subject matter of the invention only has 10 sum-and circuits. The lowering of the number of required sum-and circuits to 10 was made possible in this fixed-value addition circuit by the fact that the sum-ands 0 to 4 are processed as number 0 in a sum-and input area and the sum-ands 5 to 9 are processed as number 5. In the other sum-and input area, the odd sum-ands 1 and 3 and 5 and 7 and 9 are processed decremented by the number 1. Equalisation is carried out by means of three shifting circuits 2 to 4 which are combined with one linear circuit each. These shifting circuits (up-shifting circuits) have the shifting numbers 1 and 2 and 3. <IMAGE>

Title: Process for fabricating an intermediate carrier for semiconductor bodies
Inventor: HAGHIRI YAHYA DIPL ING
IPC: H04R25/00
Filed: 1985-06-26
Abstract: A method is expanded for fabricating an intermediate carrier for contacting a semiconductor body. Printed conductors are etched from a conductive layer, each of which have a defined external contact and an internal contact, at least the external contacts being coated. In the process, the printed-conductor pattern desired is produced in a first etching stage, the printed conductors remaining mutually connected in an electrically conductive manner. The electrically conductive connections are then passivated. Then the printed-conductor pattern is coated, the electrically conductive connections remaining uncoated. Finally, the conductive connections between the printed conductors are etched away completely.

Patent DE-3539027-A1 (DE)
Title: Control method and a circuit arrangement for a rectifier
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M7/162
Filed: 1985-11-02
Abstract: In the case of this rectifier, an electronically controllable switch (S1...S6) is connected in parallel with each diode (V1...V6). The switched-on phases of the electronically controllable switches are controlled in synchronism with the conducting phases of the associated line-commutated diodes. In consequence, the rectifier is conductive in a bidirectional manner for both current directions and is nevertheless of the line-commutated, uncontrolled type. The switching-on information items for the electronically controllable switches are derived from the currents of an auxiliary rectifier which is connected in parallel with the main rectifier to the AC voltage network. The bidirectional rectifier is preferably suitable for supplying a drive converter from an AC network, it being possible for the drive to drive and brake. <IMAGE>

Title: Guide drum arrangement for a magnetic tape in a magnetic recording and reproducing apparatus
Inventor: SATO FUMIAKI
IPC: G11B5/52
Filed: 1985-12-19
Abstract: A guide drum arrangement for guiding a magnetic tape in a magnetic recording and reproducing apparatus operating by the helical scanning technique is specified. A stationary drum of the arrangement has a tape sliding surface, which is provided with a thin film, projections or the like in at least part of the angular region between an intermediate section and the vicinity of the delivery region of the tape, so that the radius of the stationary drum is enlarged in this region. The extent of the projections is preferably adjustable. Part of the tape sliding surface adjacent to a rotating drum projects beyond the outer circumference of the rotating drum. In one embodiment there is provided an adjustable element which is fastened at one end on the stationary drum and is elastically movable at the other end by means of an arcuate slot.
Patent DE-3602687-A1 (DE)
Title: Permanent magnet synchronous machine with transverse flux paths
Inventor: WEH HERBERT PROF DR ING
IPC: H02K21/12
Filed: 1986-01-30
Abstract: Embodiments of an armature and magnet arrangement are specified with the aim of implementing large winding cross-sections with a small pole pitch in order thus to produce more favourable dimensioning and more favourable properties of electrical machines. In consequence, relatively large forces can be achieved per unit of the active pole surfaces (force densities) with lower losses in the armature winding, and thus lower utilisation of material with a high efficiency. A common feature of the proposals is that configurations of the magnetic circuits are specified whose parts enclose the armature winding on a plurality of sides transversely with respect to the movement direction, for example Figure 6. The magnetic flux is thus guided transversely, at least in subregions. Coils are provided which (related to their cross-sectional centre) have a greater extent than the pole pitch in the movement direction. They extend, for example, over more than two pole pitches before being closed in the transverse direction and running back. An approximately wave-shaped coil arrangement leads to additional material savings in the magnetic circuits and permits a reduction in the stray fluxes. As a result of their limited extent in the lateral direction, the arrangements are more suitable than conventional armature shapes (with projecting winding ends) for the design of double-acting disc machines. In consequence, very high powers can be achieved per rotor disc, as well as short structural lengths with a limited machine diameter. <IMAGE>

Title: Method and apparatus for determining pollutants in water courses and waste water
Inventor: KOSTELECKY JAN DR
IPC: G01N33/18
Filed: 1987-03-16
Abstract: In the method for determining pollutants in water courses, fresh water triclads (planaria), especially of the subspecies Dugesia dorotocephala JENKINS or of the species Bdellocephala punctata, are used. The triclads indicate the toxicity by disturbed physiological behaviour at a defined amount of pollutants (also cancer-promoting environmental toxins - including radioactive substances). Although other methods with triclads which reproduce non-sexually (transverse division) show teratogenic effects, the animals (only sexual reproduction) used in this method make much more sensitive results possible by cocoon counting and counting of healthy offspring and malformations. Screening tests (1 hour, 1 week and chronic effects of 3 to 6 months) are followed by examination of the cells under the light microscope and electron microscope. An apparatus for carrying out the method consists of a test pipe (1) through which water flows and which contains triclads, and test tanks which are filled with water and contain triclads (10). The light barriers or potentiometers (capacitance meters) (11) are connected to an amplifier (4), pulse converter (5), a pulse counter (6) and a comparator (7) to which a warning signal transmitter (8) is connected. This method is much more sensitive than all the methods used hitherto (e.g. daphnia or fish tests). <IMAGE>
Patent DE-3712950-A1 (DE)
Title: Device for determining pressure contact
Inventor: GRINJUKS ALEXANDER DIPL ING
IPC: E05F15/43
Filed: 1987-04-16
Abstract: There is a device in which a sensor hose 1 can be compressed in parts as regards the cross-section and has a receiver 6 at one end. In this case, it is desirable if the accuracy of response of the device is improved, i.e. if the device responds in an improved way as far as possible only if an in parts intensive pressure contact which is to be determined takes place. This is achieved due to the fact that the receiver is an ultrasonic receiver 6 and that an ultrasonic transmitter 4 is provided at the other end of the sensor hose 1, as well as when the ultrasonic transmitter 4 continuously transmits a signal and the ultrasonic receiver 6 records a loss of signal upon closure of the cross-section of the compressed sensor hose 1. The ultrasonic signal is lost when the entire cross-section of the sensor hose is compressed or sealed, and an only partial compression of the sensor hose over a wide area does not lead to a response of the device. <IMAGE>
