Patent EP-0347401-A2 (EP)
Inventor: KRAMER ROBERT A
IPC: H04N7/081
Filed: 1989-06-14
Abstract: A method of and system for identification and verification of TV and/or radio broadcasted program segments involves use of subaudible codes which are mixed with the conventional audio in the program segments. Individual program segments have at the beginning thereof a preamble code (such as a predetermined number of cycles of 40 Hz.), a program segment identification code (which may consist of a series of alphanumeric characters) and a postamble code (such as a given number of cycles of 40 Hz.). A plurality of radio/television broadcast stations (A-F) are monitored, the codes recovered and data sets defined, stored and later sent to a central location (31) for reconciliation and/or compilation. In the case of television stations, the video content of at least commercial message segments may be monitored to determine video signal continuity by monitoring the presence and/or absence of video signals.

Abstract: A process for removing volatile contaminants, in particular low-boiling and/or steam-volatile organic compounds from soils and comparable materials, especially those of which large proportions are in a bound/clayey form, by extraction and purification of the extracted gas contaminated with the materials to be removed is to be made more effective and economical. For this purpose, the material to be purified is introduced into a closed chamber in which a quasi-inert gas is introduced into the interior of this material and extracted again from the closed chamber after flowing through the material, purified and re-introduced to this chamber in circulation until the desired degree of purity of the material to be processed is reached. As the closed chamber, a transportable steel container can be used as one version, in which the contaminated soil material is aerated in removable grid boxes. In further versions, the treatment of the material is carried out continuously in gas-flooded screw conveyors or belt filters. <IMAGE>

Abstract: In the device for transit time compensation and eliminating the jitter of a data signal (DS) an auxiliary clock generator (TE) is provided which supplies several auxiliary clock signals (T1-T4), which are phase shifted with respect to one another by the same amount and have the frequency of the data signal (DS), and from these, a window signal (FS) having the frequency of the data signal (TF) is obtained in a signal generator (SE), which window signal has a synchronisation range which is less than or equal to half the duration of the period. In addition, a sampling clock (TR) which is within the synchronisation range is output. A counting device (BZ) changes its count into an edge of the data signal (DS) which falls into the synchronisation range and, by controlling the signal generator (SE), displaces the window signal (FS) and the sampling clock (TA) by the phase difference between two successive auxiliary clock pulses. <IMAGE>

Abstract: For use with a computer system having an intelligent mass storage disk array subsystem, including a microprocessor controller, a method for the distribution of data within the disk array based upon logical commands issued by the computer system. The disk controller reads a logical command and translates the commands into multiple drive specific commands, including drive physical parameter information such as head, sector and cylinder selection. The calculation of these physical parameters is based upon a number of factors including the operating system installed in the computer system, the type of interleave scheme, if any, specified by the computer system configuration, and disk. specific parameters. The physical drive requests are then placed in a queue and executed by the microprocessor controller. The method also encompasses a method for creating a disk array configuration to be loaded on all disks within the array based on existing valid disk array information and configuration information maintained by the computer system.

Abstract: The present invention is in an immunoassay system and process for detecting analytes and is illustrated for detecting specific antibody presence in a specimen in a short period of time as in a non-laboratory setting, such as a doctor's office. The system includes a support whereon one or more dots of a specific purified antigen to be tested for are spotted and the area around that spot or spots is preferably blocked. The support is for sequential incubations of approximately four (4) minutes each in reagent vessels containing: a specimen consisting of a diluent and a drop or drops of plasma, serum or whole blood; a high ionic strength wash solution; an enzyme conjugate; a second wash solution containing, depending upon the test procedure, a high or low ionic strength solution; and an enzyme substrate that produces a coloration of the antigen-antibody binding site of an antibody-antigen. The system of the present invention employs a high ionic strength solution as the first wash solution of from 0.25 M to saturation for removing interfering substances, presumably those substances having lower binding affinities, and for increasing sensitivity. 
     The system reagents are preferably tabletized in the manufacture and are reconstituted just prior to use. Applicant has successfully combined dry and tabletized, as the enzyme substrate reactant, a compound of 5-bromo-4-chloro-3-­indolyl phosphate (BCIP) and P-nitro blue tetrazolium chloride (NBT).

Abstract: A sample is to be removed periodically from a fermenter (1). To this end, a conveyor device (3,4) which can be programmed according to various parameters is arranged between a cooled sample storage container (2) and the fermenter (1). This device removes from the storage container (2) a test tube and brings the latter to a remote-controlled sample-removing device (5) arranged on the fermenter. By means of a control circuit, the test tube is filled and is returned to the storage container and stored under cool conditions. The sample-removing device is cleaned with water vapour after each sampling, and the contaminated vapour is guided via a tube (58) into a collecting receptacle. The process and the device operating according to the said process permit the continuous monitoring of biological processes overnight and at weekends, without the need for personnel to be present at all times. <IMAGE>

Abstract: A device is described for regulating the output voltage of a generator which is driven by an internal-combustion engine, in the case of which device an additional control device (25) is provided as well as the generator and the voltage regulator which regulates the excitation current of the generator. This additional control device (25) detects whether the motor (engine) is in the starting phase. If it is detected that the motor is in the starting phase, the control device (25) reduces the excitation current such that a voltage is produced at the generator terminal (D+) which does not permit any load current to flow and at the same time ensures that the charge monitoring indication (ignition warning light) is extinguished. After completion of the starting phase, the control device (25) is cut off and the excitation current (IE), which is regulated by the voltage regulator (11), is increased to the normal value which results in a generator output voltage which is sufficiently far above the on-board power supply voltage that the battery (20) is charged. <IMAGE>
