摘要:
What are disclosed are a method for the reinforcement of a fibrous article with an aqueous dispersion of a resin, free of formaldehyde and acrylonitrile, comprising at least 40 weight percent of alkyl acrylates and/or methacrylates having at least 4 carbon atoms in the alkyl group; up to 57 weight percent of alkyl acrylates or methacrylates having not more than 3 carbon atoms in the alkyl group, or of styrene; less than 1 weight percent of acrylic acid or of methacrylic acid; and from 3 to 15 weight percent of a hydroxyalkyl ester of an unsaturated carboxylic acid, as well as reinforced fibrous articles made by this method and distinguished by high wet strength and by low loss of the resin binder on washing with boiling water.
摘要:
A message may be used to update computing system of a commodity transaction. The message may include a commodity identifier, a date term, a quantity term, and a price term. The price term may include a formula arrangement or reference to a formula arrangement for calculating a fractional exposure of the entity to the commodity on each date in which an event affecting commodity transaction occurs. Each of these fractional exposures may be calculated for each commodity transaction and stored as separate entries in a data structure. The entries may then be updated, queried, and/or reorganized to generate an exposure position.

An analyzer module may read a selector key and a financial object number stored within a financial object. The financial object number may be sent to a selector module associated with the selector key. The selector module may read a selector strategy key stored within the financial object. A processor programmed by the selector module may retrieve a set of position values associated with the financial object based, at least in part, on the selector strategy key. A mapping module may be chosen by the selector module based upon a financial instrument type. The mapping module may store the position values within the financial object. A price calculator may generate a key figure for each of the position values. A list of the position values may be displayed to a user on a display device.
摘要:
A method for producing an instant ground meat product from at least one ground meat molded blank which is placed on a rack or a bottom of a drying chamber of a freeze-drier in order to be freeze-dried. A projection surface of the ground meat molded blank has a maximum size, such as maximum diameter or edge length, of 2 to 16 cm on the rack or tray of a freeze-drier and a maximum height of 1 to 4 cm in relation to the rack.

Methods of making iterative low-dose computed tomography (CT) efficient and applicable to clinical practice employ selection of optimal views for CT reconstruction. By optimizing the views for CT reconstruction, the method of the present invention can generate reconstructions at a pre-specified low radiation dose and/or in near real-time. A feature-oriented framework for a task-driven, object-driven, and dose-minimizing selection of X-ray views is provided, which can utilize models of features to be mapped. The models can be derived from a patient population to minimize the dose per exam and/or from a specific patient to minimize the dose per procedure. The method of the present disclosure can be incorporated into a CT system, or can be embodied in a data storage medium as a program.
摘要:
A rotary switch is disclosed which has a central handle (12) which is rotatable about a central axis (Z), a ring-shaped shield (16) surrounding the handle (12), a rotary button (18) which is arranged on the shield (16) and is rotatable about an axis (V) offset from and parallel to said central axis (Z), and a potentiometer (28) which is adjustable by means of the rotary button (18). The potentiometer (28) is radially spaced from the offset axis (V), and is coupled with the rotary button (18) by means of a gear (24, 26). The potentiometer (28) is offset radially inwards from the offset axis (V) towards the central axis (Z).
摘要:
The present invention relates to an exhaust emission control apparatus for an internal combustion engine and a process for operating it. The exhaust emission control has a particulate filter for filtering particulate matter from the exhaust of the internal combustion engine, at least one temperature sensor for detecting the temperature of the exhaust, an evaluation unit for evaluating the detected temperature, particularly with regard to a particulate mass burned during a regeneration operation of the particulate filter. The temperature sensor is positioned inside the particulate filter.

A method and device for triggering a solenoid valve for injecting fuel into an internal combustion engine is described. The triggering phase of the solenoid valve is subdivided into a pull-up phase and a holding phase. During the pull-up phase, a valve needle of the solenoid valve is caused to open by a first current intensity flowing through a magnetic coil of the solenoid valve. During the holding phase, the valve needle is held in the open state by a second, lower current intensity flowing through the magnetic coil. At least once at the beginning of the pull-up phase, a booster phase is activated during which a pulse-shaped booster current from a booster capacitor charged to a high voltage flows through the magnetic coil. During the triggering phase of the solenoid valve, a plurality of booster pulses are activated in succession, whose time position within the triggering phase is freely selectable.
摘要:
An extrusion arrangement is disclosed for manufacturing hollow-profile workpieces made of metal, including an extrusion die which is guided in an extrusion chamber and compresses material situated in the extrusion chamber. For forming an extruded hollow profile, the extrusion die presses the material through a bottom die arranged on a head-side end of the extrusion chamber, a forming of the extruded hollow profile taking place by means of internal high pressure during the emerging from the bottom die. Advantageously, a plurality of forming tools are provided which can be alternately arranged adjoining the outlet opening of the bottom die for receiving an extruded hollow profile and its forming, and, for cooling and releasing the formed extruded profile, the tools can be removed from the bottom die.
