Patent NO-170465-C (NO)
Inventor: LANTERS HENRICUS JOHANNES
IPC: B27N1/00
Filed: 1988-08-19
Abstract: The method of preparing a defibrated cellulose material, preferably wood fibres, especially those having a fibre length of up to 20 mm, involves a high proportion of thermosetting resin and is particularly suitable for preparing fibre-containing mouldings. In the process, the thermosetting resin is added in an aqueous, preferably alkaline solution to a mixture of fibre particles and steam, and the steam is removed from the resin-coated fibre particles in a dryer. After the addition of resin, the steam is removed from the mixture of steam and fibre particles which are then dried in a drying stage to a moisture content of less than 12 % by weight, especially 3 to 10 % by weight.
Patent NO-171299-C (NO)
Inventor: KELLER ERNST
IPC: B01D24/46
Filed: 1988-08-30
Abstract: A corrugated arrangement (15) is installed in the overdam chamber (3) of a filter tank (1) in such a way that, with the sludge liquor flap (8) being partially opened, direct outflow of the whirled-up granular filter material in the sludge liquor outflow (5) - and hence loss of filter material - is prevented. As a result of the novel arrangement (15), the washing water stream during the washing phase with air and water is quietened in the overdam chamber (3), so that the whirled-up grains can settle on the arrangement (15) and on the fixed bed (2) before the washing water passes into the sludge liquor outflow (5). In this way, it is possible partially to open the sludge liquor flap (8) even during the washing phase with air and water; this is desirable, for example in effluent filtration, in order to discharge relatively heavy suspended materials or to let the washing step proceed within a short time. <IMAGE>

Abstract: In a semiconductor device having at least two conductive layers disposed close to each other on an element isolating insulation film formed on a first P-type region, a second P-type region is formed in a region of the first P-type region which is between the two conductive layers.  The impurity concentration of the second P-type diffusion region is higher than the first P-type region.  A region of the element isolating insulation film which is on the second P-type diffusion region is thin to form a thin insulation film.  With the features, no inversion layer is formed in the region of the first P-type region where the second P-type diffu-sion region is formed.  As a result, the inversion layers under the conductive layers will not be in con-tact with each other.

Title: Method and device for performing arithmetic operations in the manner and with the function of an electronic calculating machine

Granted: 2003-10-21
Abstract: The invention relates to methods and devices for perform-ing arithmetic operations in the manner and with the function of an electronic calculating machine, in which the digits of the figure are automatically delimited without manual command input both in the case of manual input and in the case of automated input of the digits, and which are employed both independently and also for preprocessing at a connected EDP system.        Together with the automated delimitation of digits of the figure, the operation types are assigned to the figures in simplified manner, partially by storing an order and the combination, partially automated and without pressing a key for an operation type. A movement direction during reading-in of the digits by means of a device for charac-ter recognition is assigned a particular operation type, for example the addition is assigned to the read-in direction from left to right, and the subtraction to the direction from right to left.        A reading zone of adjustable size or, in the case of fixed reading zone, methods in the processing process as well as the input of a direction for the combination of the individual figures of the set of figures serve for determining the relevant subset from a set of figures present in written form during reading-in with a device for character recognition.        A preferred embodiment includes the performance of an addition or re-addition of a column of figures by means of a device for character recognition by combining a single recording movement in vertical direction by means of a horizontally arranged reading zone with a multi-plicative assignment of the operation type of addition, fully automatically or by pressing the addition operation key once.

Filed: 1991-01-24
Granted: 2002-04-02
Abstract: A module interfaces a programmable controller to several serial communication networks for the exchange of data carrying messages. A central processor controls the transfer of data between the module and other programmable controller components.      The module has a separate port circuit for each of the networks permitting communication using different protocols. Messages received through one port circuit can be routed to another port circuit or other programmable controller components as specified by routing data stored in the module. The module also can be configured to detect when a given sequence of data is contained in a received message or to parse a section of data from the message. In these cases, an indication of whether the data sequence was found or the parsed data is routed to a designated output of the module.

Title: Intelligent computer integrated maintenance system and method
Inventor: JOHNSTON MICHAEL Z
IPC: G06Q10/06
Filed: 1991-06-05
Granted: 1998-05-19
Abstract: An intelligent computer integrated maintenance system and method may be used with a group of machines which require maintenance, known as a "complex", such as a group of production lines each of which includes many production machines for producing a product.  The intelligent computer integrated maintenance system includes an electronically stored parts manual which contains a hierarchical listing of all parts in the production machines.  The hierarchical listing contains a complete bill of materials which breaks each machine into subassemblies and breaks each subassembly into its subassemblies down to the level of individual parts.   The intelligent computer integrated maintenance system also includes a maintenance operations computer controller which includes a maintenance schedule management subsystem, an engineering change control subsystem, a parts manual management subsystem and a spares inventory management subsystem. The maintenance schedule management subsystem obtains a schedule of actual and planned production system and groups maintenance activities in order to minimize the lost production time for each complex.  For example, maintenance is scheduled for off-line times for each complex if possible. Alternatively, if a number of maintenance tasks are scheduled for a short time interval, they may be grouped together so that they can be performed simultaneously.           The engineering change control subsystem integrates engineering change activities with maintenance activities to maximize production time. The automated parts manual is also updated to account for engineering change controls.  The spare parts inventory management subsystem orders spare parts based on predicted maintenance rather than on prescribed inventory levels.  Just-in-time parts ordering is thereby facilitated.          The computer integrated maintenance system and method of the present invention allows maintenance operations to be integrated into the complexes primary activity, such as production, in an intelligent manner. When used, production efficiency is maximized as is the use of available maintenance manpower.  Engineering changes are easily accommodated and spare parts inventory is kept to a minimum.

Title: Recombinant therapies for infection and hyperproliferative disorders
Inventor: GOLDSMITH MARK A
IPC: C12N15/86
Filed: 1991-07-18
Granted: 2001-07-03
Abstract: Host cells may be treated for an infection or a hyperproliferation disorder which is characterized by the presence, in the affected cells, of a trans-acting factor capable of regulating gene expression by inserting into the cells a polynucleotide construct having a cis-acting regulatory sequence which is regulated by the trans-acting factor and an effector gene which renders said cell susceptible to protection or destruction. For example, the cis-acting region may be homologous to the HIV tar region, and the effector gene may encode ricin A or HSV-1 thymidine kinase. Upon infection with HIV, the HIV tat protein activates the tar region, and induces transcription and expression of ricin A, resulting in cell death, or of HSV-1 tk, resulting in cell death upon treatment with dideoxynucleotide agents such as acyclovir and gancyclovir.
