Patent EP-0399202-A3 (EP)
Title: High frequency branching directional coupler
IPC: H03H7/48
Filed: 1990-04-14
Abstract: The present invention relates to branching directional couplers with a voltage and a current transformer and an internal terminating resistance, in which the junction of the secondary windings of the two transformers forms the branch and the internal terminating resistance is inserted between the secondary winding of the voltage transformer and earth. To achieve branch attenuations of >/= 16 dB in such a branching directional coupler, with little circuit complexity over a wide band up to 1.75 GHz with little transmission loss, a high degree of decoupling and good matching of all connections, an ohmic resistance connected in parallel with the secondary winding of the current transformer and connected to the latter with low inductance is provided which, together with the transformation ratios of the two transformers, is selected in such a manner that the nominal values for the branch attenuation and impedance are obtained as accurately as possible at the branch connection. By inserting a further ohmic resistance between the junction of the secondary windings of the two transformers and the branch connection, a further degree of freedom has been advantageously achieved for the choice of resistances and transformation ratios. <IMAGE>

Title: Method and apparatus for centrifuging high-viscosity material
IPC: C13B30/06
Filed: 1990-09-20
Abstract: 2.1 A method in which two or more centrifuging stages situated spatially one above the other with intervening mashing are carried out in a common housing has not hitherto been possible in the case of highly viscous suspensions or/and suspensions which tend to form lumps. Such a method is used, for example, in the sugar industry, to treat the second sugar massecuite, and the object of the invention is to make it usable also for such highly viscous massecuites. 
<??>2.2 This object is achieved in that, before it enters the first centrifuging stage, the material to be centrifuged is viscosity-reduced and homogenised by the action of shearing force to such an extent that it can be fed to the centrifuging as a creamy massecuite and distributes itself uniformly on the screen of the first centrifuging stage. 
<??>2.3 This method is suitable for all highly viscous suspensions or/and suspensions which tend to form lumps, in particular in the sugar industry for treating the low-grade sugar massecuite, the so-called C sugar.

Title: Polycrystalline cvd diamond substrate for single crystal epitaxial growth of semiconductors
IPC: H01L21/20
Filed: 1991-01-25
Abstract: The present invention is directed towards the production of a single crystal semiconductor device mounted in intimate contact with a polycrystalline CVD diamond substrate which allows the high heat conductivity of diamond to keep the device cool. This device is made by a method comprising the steps of placing in a reaction chamber, a single crystal of silicon heated to an elevated CVD diamond-forming temperature. A hydrocarbon/hydrogen gaseous mixture is provided within the chamber and is at least partially decomposed to form a polycrystalline CVD diamond layer on said silicon. During this deposition/growth phase, an intermediate layer of single crystal SiC has been found to form between the single crystal of silicon and the polycrystalline CVD diamond layer. In the next step of the process, the silicon is etched or removed to reveal the single crystal SiC supported by the polycrystalline CVD diamond layer. Finally, a semiconductor layer (e.g. silicon, SiC, GaAs, or the like) is grown on the exposed single crystal of SiC to produce a single crystal semiconductor polycrystalline CVD diamond mounted device.

Title: Apparatus for optical record carrier having a disc shape.
Inventor: BAAS DIETER
IPC: G11B19/02
Filed: 1993-10-13
Abstract: The device moves the fed-in recording medium (7) in a direction perpendicular to a swivelling axis to attain an operational position for action by an optical scanner (14). A reflective photosensor assembly (6, 11) is fitted on the same side of the recording medium as the scanner. This causes a signal to branch off, if the recording medium crosses light rays from the reflective photosensor assembly in an intermediate position different from the operation position. A drivable platen (3) perpendicular to a swivelling axis moves the recording medium. The reflective photosensor assembly switches the platen driver on or off upon a reverse movement to eject the recording medium before the platen releases the recording medium. The reflective photosensor assembly is fitted between the platen and the optical scanner.

IPC: A23L19/00
Filed: 1993-10-27
Abstract: A process for reordering tobacco, which results in no significant decrease in equilibrium tobacco CV or significant tobacco degradation, is provided. Tobacco to be reordered is contacted with an air stream having a relative humidity near the equilibrium conditions of the tobacco. As the ov content of the tobacco increases, the relative humidity of the air stream contacting the tobacco is increased to affect reordering of the tobacco. Also provided is a process for drying tobacco, which results in no significant change in equilibrium tobacco CV or significant tobacco degradation. Tobacco to be dried is contacted with an air stream having a relative humidity near or below the equilibrium conditions of the tobacco. As the OV content of the tobacco decreases, the relative humidity of the air stream contacting the tobacco is decreased to affect drying of the tobacco. It has been found that tobacco can be reordered or dried successfully in a continuous manner using a self-stacking spiral conveyor. <IMAGE>

Filed: 1995-12-27
Abstract: In a decision feedback equalizer, transmitted signals are received by
an array of antennas and baseband symbols are recovered. A forward filter
provides weighting of the recovered baseband symbols with first coefficients
so that precursor multipath components of a transmitted symbol are
canceled and combines the weighted symbols. A set of first delay elements
provide respective delays to one of the baseband symbols to produce a short-
and a long-delayed baseband symbol. A set of correlators is provided for
detecting correlations between the baseband symbol and the short- and
long-delayed baseband symbols. A set of second delay elements provide
respective delays to a decision symbol to produce a short- and a long-delayed
decision symbol. A selector is responsive to a correlation detected
by one of the correlators for selecting one of the short- and long-delayed
decision symbols. A feedback filter shifts the selected decision symbol along
a tapped-delay line to produce successively shifted decision symbols,
multiplies them with second coefficients and combines the multiplied
decision symbols to produce an output signal that cancels postcursor
multipath components of the transmitted symbol. The output signals of the
forward and feedback filters are combined to produce a pre-decision symbol
which is used by a decision circuit to produce a decision output for coupling
to the second delay elements as the aforesaid decision symbol.

IPC: G07F5/24
Filed: 1996-03-01
Abstract: A method and apparatus for accepting coins of denominations that have and do
not have coin tubes for making change in a coin mechanism is described. One aspect of
the invention concerns a method for calculating an overpay amount. The overpay
amount is set to equal the value of the lowest value coin with a tube minus the value of
the lowest value non-tubed coin. Thus, when the lowest value coin tube is empty
a vending machine customer will be permitted to insert low value, non-tubed coins up to
the overpay value to increase the likelihood of enabling a vend of an item to take place.
Another aspect of the invention relates to the acceptance of high-valued, non-tubed
coins. The high-value non-tubed coins are acceptable if adequate change exists in the
coin tubes to payback their value plus the value of any existing credit, if their value plus
any credit value is greater than the maximum vend price, and if each of the vend prices
in the vending machine permit adequate change to be returned to the customer.
