Title: Core drill which can be folded open and has a capture device for taking undisturbed soil samples in the depth range down to 1.5 m
Inventor: GORNY HORST
IPC: E21B25/10
Filed: 1984-07-05
Abstract: This drill makes it possible to obtain an undisturbed soil core in any desired length up to 1.50 m. There is no pressing or compaction of the drill core. The unavoidable soil displacement by the drill casing takes place outwards into the surrounding region. Due to the capture device in the cutting head, even fine-grained soil samples can be taken. The separation of the inner pipe into two half-shells allows unhindered removal of the soil core in its entire desired length up to 1.50 m, and also an exact rebedding of the drill core in transport half-shells for the purpose of subsequent extensive evaluations in soil laboratories and institutes. The pitch of the thread on the outer pipe allows use in manual operation. For this purpose, a manual drill set is available.

Title: Method for driving piggyback memory chips
Inventor: BOCK FRANZ-DIETER
IPC: G11C8/12
Filed: 1984-09-27
Abstract: In a memory constructed of piggyback chips, two piggyback chips (X,Y) of two single chips each (X1,X2,Y1,Y2) are provided for each data bit to be loaded or to be read out with a memory access. The chips are activated by address transfer signals. When a streaming command is executed, the memory control device (SG) generates four time-sequenced transfer signals (1RAS-4RAS) for the chip-internal row address and alternately two transfer signals (1CAS,2CAS) for the chip-internal column address. The order in which these transfer signals are supplied to the single chips (X1,X2,Y1,Y2), and thus the selection of the single chips, is determined by the two least-significant bits A0, A1 of the start address. <IMAGE>

Title: Aerial input circuit
Inventor: FISCHELMAYER HEINRICH
IPC: H04B1/18
Filed: 1985-01-10
Abstract: An aerial input circuit for a radio receiver is described, which is designed at least for reception of transmitters in the short-wave and/or medium-wave range and is intended for connection to a capacitive aerial system. Such an aerial system can be characterised by the series connection of two capacitances fed from a voltage source, namely an aerial capacitance and a cable capacitance. In the choice of the individual wave ranges, in each case the aerial input has connected to it in parallel a particular inductance which is of such a rating as to compensate substantially for the cable capacitance of the aerial system in effect at the aerial input and causing interference for the wave ranges concerned.
Patent DE-3500968-A1 (DE)
Title: Sales stand, preferably made of metal wire
Inventor: TWEEL FRANCISCUS VAN DER
IPC: A47F5/05
Filed: 1985-01-14
Abstract: A sales stand, preferably made of metal wire, is fitted together from demountable column parts 13 of short length. Said column parts can be screwed together, for example, and are fitted with a foot so that a stable column is produced. The sales baskets are connected rigidly to the column parts which also serve as spacers. For this purpose, each sales basket is provided in its centre with a reinforcement in such a way that a quite rigid connection is thus provided with the column parts. The advantage is produced during transportation since the column, the sales baskets and the foot can be packaged in a single case which corresponds to the circumference of the largest basket dimension, but is no higher than, for example, the foot or the height of the partition grids if the latter are used. Even without a packaging case, the space required, for example in a passenger car for numerous sales stands, of which the baskets can nest in one another, is thus very small and extremely favourable compared to the known stands. The stability can be increased greatly since the division of a column can take place both in the longitudinal and in the transverse direction. <IMAGE>

Title: Wheel-chair, especially for sports purposes
Inventor: PURKOTT ERICH
IPC: A61G5/10
Filed: 1985-05-11
Abstract: Perforated plates having holes arranged in a predetermined grid are located on parts of the chassis frame that are remote from each other. These holes are intended to selectively receive the hub axle of the particular drive wheel, so that individual adjustment of the wheel-chair in terms of height and inclination of the seat is possible. The perforated plates are connected via adjustable fixing screws with supporting strips of the chassis frame in such a manner that within predetermined limits the distance of each corner of the perforated plate from the supporting strips of the chassis frame can be adjusted individually. In this way, it is possible to vary the track and camber of the drive wheels within predetermined limits and adjust them in such a way that the drive wheels do not grind in driving operation and that easy running of the wheel-chair is guaranteed.
Patent DE-3523175-A1 (DE)
Title: Artist's brush
Inventor: LECHNER REINER
IPC: A46B7/04
Filed: 1985-06-28
Abstract: There are in existence artist's brushes which in each case have a brush head 1 and a brush handle 6 and in which in each case brush head and brush handle are held together by means of a connecting device in which a peg 12 is guided in a hollow 13. In this connection, it is desirable for the number of brush components necessary for a large number of head-trim/handle combinations to be decreased. This is achieved in that the pegs 12 and hollows 13 of the connecting devices of the different artist's brushes all fit each other and the connecting devices are constructed such that they can be easily detached and interchanged, such that the components are combined with the different head-trims 2 and the different handles 6 to form an increased number of different artist's brushes. The cost of head-trim and handle is clearly lower in view of the possible number of head-trim/handle combinations. <IMAGE>

Patent DE-3532641-A1 (DE)
Inventor: JAECKLIN FELIX PAUL DR SC TECH
IPC: E02D29/02
Filed: 1985-09-12
Abstract: The wall according to the present invention comprises a gravity support structure with a plurality of compartments or cells which are filled with bulk-material and surrounded or subdivided by flat and flexible envelope material, and on one front side or on both opposite front sides of this gravity support structure a fore-part, preferably in the form of a supporting grid structure, which is positively or frictionally connected with said gravity support structure. Such combined wall structure can be used for slope supporting as well as for noise absorbing or partition purposes, in the latter cases e.g. in the form of a stand-alone structure. An essential function of the fore-parts is the protection of the front portions of the envelope material holding the bulk material filling against violation and solar irradiation. The stability of the combined wall is greatly enhanced by anchoring the fore-parts to the gravity support structure be means of comparatively inexpensive tensile elements.

Patent DE-3608741-A1 (DE)
Title: Rotary filter
Inventor: QUASCHNER KARL WILH LUDWIG
IPC: B01D46/26
Filed: 1986-03-15
Abstract: The rotary filter has the object of separating the dust content from air with the lowest possible expenditure in comparison with previous dedusting processes. As a result of its mode of operation and the appropriate construction of a rotating bag drum, it is able to filter dust in the most material-saving and energy-saving manner possible. Since the dusty air runs in the same direction as the bag drum, mechanical stress in comparison with previous processes is very small. Moreover, the dust is separated off again at the same velocity as it impinges the material. This process produces a high dust loading of the bag and thus a more efficient capacity utilisation.
