Abstract: The absorbent domestic cleaning cloth for cleaning and/or drying household articles is to be designed in such a way that despite great absorbency, it cannot be penetrated by the absorbed moisture. This is achieved in that the domestic cleaning cloth is made up of two layers consisting of a water-proof plastic film (13) and a coating (14) applied thereto made of a highly absorbent material. A domestic cleaning cloth of this type can be used in a variety of ways in the household and prevents penetration of moisture in the direction of the water-proof plastic film (13). <IMAGE>

Abstract: Verfahren zur Isolierung von Alkalisulfat-armen Alkansulfonaten und Schwefelsäure aus Paraffin-Sulfoxidations-Reaktionsgemischen mit Hilfe von Alkoholen, wobei man das von Schwefeldioxid befreite Reaktionsgemisch in einer Folge von fünf Misch-Absetzgefäßen mit einem C4-C8-Alkohol und der zur Neutralisatoin erforderlichen Menge an Alkalihydroxid versetzt. Das Verfahren ist so angelegt, daß kein Alkalisulfat als Nebenprodukt anfällt, sondern nur Schwefelsäure. Dadurch gehen weniger Alkali-Ionen aus dem System verloren und demgemäß verringert sich der Verbrauch an Alkalihydroxid für die Neutralisation.

IPC: G06F17/50
Filed: 1987-12-09
Abstract: Detail routing of connections among blocks on a carrier is accomplished by determining an initial placement for first, second and third blocks with respect to a stationary frame of reference. The initial placement is such that the three blocks do not overlap and the first block is separated from the second block by a first channel and the third block is separated from the first block by a second channel. The first channel abuts at a one end with one side of the second channel. Each channel has real terminals along its sides. The position of a real terminal in the longitudinal direction of the channel is defined before detail routing of the channel takes place. The first channel has virtual terminals at the end at which it abuts the second channel. The path followed by connections among terminals of the first channel are then defined and the width of the first channel is adjusted to accommodate the connections by adjusting the position of the second block in a direction perpendicular to the longitudinal direction of the first channel and without altering the position of the first block. The positions in the transverse direction of the first channel of the virtual terminals at the end of the first channel are defined, and these virtual terminals thereby become real terminals with respect to the second channel. The paths followed by connections among the terminals of the second channel are subsequently defined.

Abstract: For this system, two transportable radar beacons are provided as ground installations which are set up as markings at the beginning and end of an intended landing runway, particularly an auxiliary landing runway. Via interrogation signals defined in frequency and/or coding from the on-board radar of the aircraft, the radiation of response signals which, in turn, are defined in frequency and/or coding but are different from the interrogation signals, is triggered in the beacons. The relative position of the landing runway is calculated and indicated from the response signals received by the on-board radar. <IMAGE>

IPC: G01N21/76
Filed: 1987-07-08
Abstract: An oxygen sensor is provided for determination of the partial pressure of oxygen. In one aspect, the invention consists of oxygen-­quenchable luminescent lanthanide complexes for an oxygen sensor. The complexes are oxygen-quenchable even though immobilized in a solid matrix, such as a solid polymeric matrix, and preferably are terbium complexes of Schiff base of β-diketone ligands. Certain preferred processes are described for improving the oxygen sensitivity of the lanthanide complexes. In another aspect, the invention consists of a combination measuring and reference analyte sensor containing both quenchable and nonquenchable luminescent material. The materials luminesce at different wavelengths and thus may be transmitted together down a single optical fiber and later descrimininated by means of filters and separately detected. In a third aspect, the invention consists of a low-noise phosphorescent analyte sensor employing a gatable detector. By use of an analyte-quenchable material having a relatively long-lived phosphorescence, a pulsed excitation source, and selectively coupling the detector after the excitation source is off and any short-lived background luminescence has ended, a low-noise output signal consisting of the long-lived   phosphorescence is selectively detected and the concentration of the analyte determined therefrom. In a preferred embodiment, all aspects of the invention are combined to produce a miniature in vivo oxygen sensor for use in the narrow blood vessels of the body.

Abstract: To generate pseudo-random bit sequences of high statistical quality, a clock-manipulated autonomous automatic device, for example a maximum-length shift register (1) is clocked as a function of its output signals. For example, d clock steps are executed with an output signal 0 and k clock steps are executed with an output signal 1, for generating the next output signal. The bit sequences thus generated have predictable and improved statistical characteristics whilst maintaining a simple circuit configuration. <IMAGE>

Abstract: A method for self-aligning an isolation structure to a diffusion region. A first masking layer is formed on a semiconductor substrate, the first masking layer having at least one aperture sidewall which is sub­stantially perpendicular to the semiconductor sub­strate. Dopant ions are implanted into the semiconduc­tor substrate through the first masking layer to form a doped region. Sidewall spacers are then defined on the sidewalls of the aperture, and a sidewall image reversal process is carried out such that the sidewall spacers define trench apertures in a masking struc­ture. Finally, isolation trenches are etched into the semiconductor substrate through the masking structure. Alternatively, the implantation step is carried out after the sidewall spacers are defined on the first masking layer. Alternatively, first sidewall spacers are defined, followed by the implantation step and the formation of second sidewall spacers.

Abstract: High availability is achieved in a multiprocessor system by grouping the processors into two clusters operating on different clock and power boundaries. In each cluster is an array containing a substantially identical copy of the system information relating to the operation of the processors. Each processor has a local port for accessing the local array and a remote port for accessing the remote array. When an update is made on the system information, it is made on both the local and remote arrays with the remote update performed transparently.

Abstract: The present invention relates to a process for producing glycol esters by reacting lower aliphatic carboxylic acid and olefin in the presence of a catalyst containing (A) a pal­ladium component, (B) a metal component selected from the metals of Periodic Table Groups IA, IB, IIA, IIB, VA, VIIB and VIII, (C) a halogen component and (D) a nitrogen-containing oxide, and oxygen. The first process is characterized in that a halogen ion source and/or a nitric acid ion source is added in the course of the reaction. Further, the second process is characterized by including:
     (1) a step in which after the reaction, hydrogen is introduced to reduce the palladium catalyst;   (2) a step in which the reduced solution obtained is separated into reduced palladium and the reaction solution by filtration;   (3) a step in which the reaction solution is distilled to separate the lower aliphatic carboxylic acid and the glycol esters; and   (4) a step in which to the reduced palladium obtained in the step (2) above, a lower aliphatic carboxylic acid, the distillation residue obtained in the step (3), a halogen ion source and/or a nitric acid ion source are added to prepare a catalyst solution, and the catalyst solution is introduced in the reaction system.   
     According to the present invention, the selectivity is   increased and also the separation of the product from the reaction solvent is facilitated. Further, the process can be carried out continuously, and the catalyst can be used repeatedly.
