Patent DE-4213605-A1 (DE)
Title: Cordless telephone with communication channel connection - blocking speech until normal response to signal transmitted between auxiliary unit and main unit is obtained
Inventor: KAMIMOTO KOUICHI
IPC: H04M1/72511
Filed: 1992-04-24
Abstract: The cordless telephone has a main unit (12) and an auxiliary unit (19) which communicate with one another via a number of different channels, the engaged channel determined via a channel switching device (16, 23) coupled to a channel selector (18, 26) operated by the user, at both the main unit and the auxiliary unit. A speech channel between the units (12, 19) is established when a normal response is obtained for a signal transmitted from the auxiliary unit to the main unit, with switching back to an initial channel when a normal response is not obtained, for re-transmission of the signal. ADVANTAGE - Allows communication link to be established after temporary disconnection of main unit.

Title: Interpolative, predictive image data compression system - provides movement compensation for each image block using estimation block obtained by various different prediction methods
Inventor: MAY FRANZ DR ING
IPC: H04N19/503
Filed: 1992-06-29
Abstract: The data compression system uses predictive image coding with movement compensation. The image is divided into blocks contg. a defined number of image points, with a movement compensating estimation block provided for each image block using the preceding images. A decision relating to the prediction method is made as to whether the shifted or un-shifted blocks of the preceding image, or the image preceding the immediately preceding image are used, as to whether no prediction is made, or as to whether the weighted mean of both preceding images are used as the estimation block. ADVANTAGE - Good image quality and smooth movement for reduced data rate.

Title: Receiving or processing electronic signals - passing signals through selection circuits with multiplexers whose clock frequency determine middle frequency of selection.
Inventor: RUMP HANNS
IPC: H03J5/00
Filed: 1992-09-19
Abstract: The method involves receiving or processing electronic signals in particular band widths. The signals are passed through selection circuits (4-15). The selection circuits include clock controlled multiplexers to implement the selection. The clock frequency of the multiplexer determines the middle frequency of the selection. The multiplexer switches through several capacitances under clock control. The capacitances in a low pass circuit are each replaced by a multiplexer which switches though a number of capacitors. The capacitances do not necessarily have to be connected on one side to ground potential. USE/ADVANTAGE - Ultrasonic distance measurement or proximity circuits. Material examination, and medical applications. Microphone amplifier with bandpass characteristics. Enables high value filter or receiver to be realised at comparatively low cost.

Patent DE-4236103-A1 (DE)
Inventor: SCHLOSSER HUBERT DR
IPC: C09K19/40
Filed: 1992-10-26
Abstract: The invention concerns a method of preparing polycyclic aromatic compounds by crosslinking aromatic boron acids with aromatic halogen compounds or perfluoroalkyl sulphonates in the presence of metallic palladium, optionally on a carrier, as catalyst. The method is characterized in that the crosslinking is carried out in the presence of a ligand and a base. The method disclosed enables the yield of polycyclic aromatic compounds to be increased significantly compared with methods in which no ligand is used, i.e. it ensures optimum yields in the pd(O)-catalysed crosslinking of aromatic boron acids with aromatic halogen compounds.

Title: Coil structure for a printed circuit board arrangement
Inventor: FUCHS ANDREAS
IPC: H05K1/03
Filed: 1993-03-02
Abstract: It is known for conductor tracks on printed circuits to be structured so that they form significant inductances. The electrical values of the spiral or meandering printed flat coils are in the orders of magnitude of comparable conventional coil designs. The disadvantage in this case is primarily that the two-dimensional construction results in a relevatively large space requirement on the surface of the board and that the use of ferrite cores and trimming are virtually impossible. The printed coil according to the invention consists of in each case one group of parallel conductor track sections 2, 3 on the two side surfaces of a double-sided printed circuit board 1 or on the outer surfaces of a multilayer arrangement, and of through-plated holes 4 which connect the conductor track sections 2 and 3 to form a helix with a rectangular cross-section. The principle also allows bifilar structures and the design of highly effective transformers. A ferrite core can be inserted axially - as in the case of air-cored coils - for trimming and in order to increase the inductance, for example if a slot 5 is arranged in the board material between the conductor tracks, or a passage is arranged within the multilayer construction. The structures according to the invention are virtually equivalent to conventional coils but have technological and cost advantages. <IMAGE>

Title: Aerodynamic device having at least one inflatable, flexible wing
Inventor: MELITOPOULOS JORDANIS
IPC: B64D17/02
Filed: 1993-03-17
Abstract: According to the invention, the uppermost stage of the load distribution system of a paraglider or of a similar aerodynamic device is intended to be embedded in the interior of the flexible wing or wings, as a result of which the residual drag of the supporting lines is reduced. The load distribution in the span direction is not intended to end at the bottom of the wing, but is intended to continue into the interior of the wing. To this end, the uppermost junction point at which lines branch in the span direction is arranged essentially in the interior of the wing. Alternatively or in addition, ribs or ribbed parts are laterally braced using lines essentially in the span direction, as a result of which the load distribution in the span direction is likewise improved.

Title: Power station (generating station, power plant) operating by means of a fossil fuel requiring to be dried, in particular by means of brown coal (lignite)
Inventor: HEITMUELLER RALF DR ING
IPC: F23J15/00
Filed: 1993-07-14
Abstract: Arranged downstream of the convection passage (flue) is a fly ash separator (collector) through which the entire quantity of flue gas flowing is guided. The pulverising and drying system is connected to the gas side of the fly ash separator, and a mixture of finely ground fuel and vapours issues from the pulverising and drying system. Arranged between the flue gas cleaning system and the pulverising and drying system is a device for separating solids, into which the finely ground fuel and the vapours issuing from the pulverising and drying system enter and can be drawn off separately. A vapour line which leads to the flue gas cleaning system is connected to the vapour extractor of the device for separating solids. The device for introducing the ground and dried fuel has a component flow line branching off from the vapour line, with the result that the finely ground and dried fuel issuing from the device for separating solids can be introduced into the furnace of the power station boiler with the aid of a partial flow of the vapours. The device for feeding the combustion air to the power station boiler has an air heater (air preheater) heat exchanger which can be heated by means of steam from the steam turbine system. Overall, the power station system is designed such that the component flow of the vapours, by means of which the finely ground, dried fuel can be introduced into the power station boiler ...

Title: Press for moulding compounds made of powder
Inventor: GABRIEL REINHARD
IPC: B30B15/00
Filed: 1993-09-08
Abstract: In the case of a press for compacting moulding compounds made of powder, especially finely disperse moulding compounds, to make moulding bodies, the stamp and the stamp head 5 are provided with channels which are connected to an air evacuation device and a releasable interceptor 6 is mounted upstream of the operating surface of the stamp head.
