Title: Use of  alpha -trans-bergamotol derivatives as perfumes and odorants
Inventor: BRUNKE ERNST-JOACHIM DIPL-CHEM
IPC: C11B9/00
Filed: 1982-02-15
Abstract: The invention relates to the use of the  alpha -trans-bergamotene derivatives of the formula I as perfumes and odorants, where R is a hydroxymethyl, formyl, carboxyl, acetoxymethyl, propoxymethyl, carbomethoxy or carboethoxy group, and the dotted line means an optional double bond with (Z) geometry. <IMAGE>   The (Z)- alpha -trans-bergamotol (1a) was obtained for the first time from East Indian sandalwood oil and has unexpected olfactory properties not hitherto ascribed to sandalwood oil. Syntheses for the bergamotol derivatives 1a-o are described (Examples 1-7). The olfactory properties of these compounds make it possible to use them advantageously as perfumes and odorants or component of perfume or odorant mixtures (Examples 8-10).
Patent DE-3216365-A1 (DE)
Title: Entertainment electronics device with a picture and/or sound signal transmission path and a data transmission arrangement connected to the latter
Inventor: SCHROEDER WOLFGANG DIPL ING
IPC: H04N7/088
Filed: 1982-05-03
Abstract: A data transmission arrangement (5, 50) for the transmission of a repeatedly transmitted data record of a constant number of data words, which record is located on the signal transmission path (1) for picture and/or sound information of an entertainment electronics device, to an evaluation circuit (11) of the device, includes an intermediate memory (7), into which the counted-off number of data words read out by an isolating circuit (2), corresponding to the length of a record, are stored directly after switching on the data transmission arrangement. The counting of a parallel counting word counter (28) is stopped when a marking word identifying the beginning of the data record is detected. The counter reading of the said word counter in the stop position is the initial counter reading for the read-out sequence of the data record stored in the intermediate memory, which in this way is transmitted to the evaluation circuit beginning with the first word of the data record and in the correct sequence of the data words, although the operation of writing to the intermediate memory was commenced at any desired data word of the data record. By the measures of the invention, the otherwise usual waiting time between switching on and the occurrence of the beginning of the record is already utilised for a storing operation and the writing time is shortened by the amount of waiting time. <IMAGE>

Title: Electrical desired-value sensor
Inventor: KAHLEN HANS DR DR ING
IPC: G01D5/251
Filed: 1982-05-12
Abstract: The invention relates to an electrical desired-value sensor in the form of a voltage divider constructed from discrete resistors (R1...Rn), on which voltage divider partial voltages can be picked off via barrier-gas switching contacts (S1...Sn) which can be operated magnetically. Such desired-value sensors are preferably used for controlling electrical prime mover vehicles, to be precise for predetermining the speed or rotation speed. The barrier-gas switching contacts can be driven by a permanent magnet (3) having a magnetic shunt path (4), so that the switching contact located in the upwards counting direction is connected with little hysteresis. The barrier-gas switching contacts (S1...Sn) are fitted on a stationary circular segment (5). In order to convert a predetermined operating movement, for example an accelerator movement of a car, into an adjusting movement, the permanent magnet (3) and the magnetic shunt path (4) are located on a magnet support (1) which moves around a rotation axis (2). The individual switching contacts are successively opened and closed by rotation of the magnet support. The first connections of the switching contacts in each case can have a supply voltage (UE) applied to them via a resistor series circuit. The connections of the switching contacts which are in each case second are connected to one another and are connected to earth potential via a fixed resistor (RO). <IMAGE>

Title: Method and device for recording and storing curves of forced expiration
Inventor: GUTA ISTVAN
IPC: A61B5/091
Filed: 1982-08-03
Abstract: In the method according to the invention, a constant volume increment is determined; in the course of expiration, those periods are measured and stored which are necessary to change the volume of the expired air by the given increment; furthermore, a count is kept of how frequently the volume of the expired air changes by the given increment during expiration, after which the periods required to reach the previously determined volume increment are compared in sequence with a prescribed period; as soon as the period required to reach the volume increment becomes longer than the given period, the recording of the expiration curve is terminated. In the proposed device, the respiration meter is connected via a measuring transducer to a computing unit (16) which is provided with a display (17) and a supply unit (19). The measuring transducer contains mechanically attached, periodically repeating elements which are arranged at spaces of equal distances corresponding to a given volume increment; the computing unit (16) contains a microprocessor which has a memory and whose interrupt input is connected via a signal convertor to the output of the measuring transducer. <IMAGE>

Title: Circuit arrangement for demodulating a frequency-modulated signal
Inventor: DEMMER WALTER ING GRAD
IPC: H03D3/02
Filed: 1983-04-25
Abstract: To demodulate a frequency-modulated signal in digital representation, the successive digital values are supplied to a multiplier directly via one input and via a delay section via the other input. The product supplied by the multiplier contains a signal component with twice the frequency of the frequency-modulated signal supplied, which is filtered out by a low-pass filter. Furthermore, a signal component exists which contains the instantaneous frequency of the frequency-modulated signal. An essentially linear demodulation is obtained if the delay time of the delay section 4 corresponds to one quarter of the mean period of the input signal. The low-pass filter is suitably formed from a shift register, a number of multipliers which can be implemented by means of adders, and a summing circuit, as digital transversal filter. <IMAGE>

Title: Multiconductor layer structure for monolithic semiconductor integrated circuits
Inventor: ISBELL TIM D
IPC: H01L23/522
Filed: 1983-09-12
Abstract: In a monolithic bipolar silicon semiconductor integrated circuit having an insulated p-n junction, devices which can be operated at high voltage are made possible by using a structure comprising two conductor layers. The first layer comprises polycrystalline silicon which is doped to obtain a suitable conductivity and coated with an insulator. The second layer comprises the standard aluminium metallisation. The first layer is arranged so as to cover the critical pn junction which carries high voltage and it is connected to the more heavily doped side of the junction by an ohmic lead. The first metal layer extends over the planar oxide layer so as to cover the junction and the depletion zone or barrier layer. The latter is covered by the first conductor layer, in particular at the point where the second layer extends across the junction, thereby screening the depletion zone or barrier layer from the second layer so that the diode breakdown voltage cannot be affected adversely by the potentials on the second metal layer.
