摘要:
A method for displaying regions of a matrix. The matrix has at least one column and one or more rows having one or more fields related to individual data records. The method comprises: displaying a starting region of the matrix, the starting region having one or more rows with each row having a field corresponding a data record; determining a field corresponding to the matrix position which the computer user indicates via a first user interface; obtaining a data record to which the determined field is related; identifying the rows of the matrix relating to the obtained data record; displaying, on detection of a user request via a second user interface to continue to display, a second region of the matrix which contains at least one identified row.

A process for treating textile fibers involving contacting the fibers with a composition containing: (a) a compound corresponding to formula I: R—COO(CH2CH2O)nH (I) wherein R is a linear or branched, saturated or unsaturated alkyl or alkylene group having from about 5 to 21 carbon atoms and n is a number from about 0.5 to 1.5; (b) optionally, an emulsifier; and (c) optionally, a co-lubricant.
摘要:
A refrigeration device and method of operation, including at least two separate temperature zones, each having a set temperature range. Both zones are cooled by a separate condenser with both of the condensers arranged in a common coolant circuit having operational and non-operational phases. At least one temperature zone includes a fan and the temperature is measured in at least a first one of the temperature zones. The fan is operated intermittently in the operational and non-operational phases depending on a preset temperature measured in the first temperature zone. The operational and non-operational phases of the fan and the coolant circuit are operated such that the operational phases of the coolant circuit coincide at least partially with the non-operational phases of the fan.
摘要:
A device for producing individual metal contact parts for electrical connectors includes a processing machine for processing a semi-finished product to assemble the electrical contact parts as one unit on a strip. The device includes a packaging device connected downstream of the processing machine in the direction of travel of the strip. The packaging device includes an exchangeable storage and transport module such as a spool for receiving a given length of the strip formed by the individual, assembled contact parts. A marking device is mounted between the processing machine and the packaging device. The marking device places an identification on each of the individual contact parts on a length of a strip assigned to the spool. The identification characterizes the strip segment and is different from the identification of other strip segments on other spools. The marking device marks the individual contact parts in the form on an impression.

A method of coating a substrate by magnetron cathode sputtering includes a sputtering cathode having pole shoes and being arranged in a vacuum chamber. A target and a magnetic field are provided in an area of the surface of the target and the magnetic field is varied stepwise and/or continuously to displace the plasma radially such that the erosion groove is likewise displaced radially. The variable magnetic field is generated by coils between the back surface of the target and a yoke plate while a static magnetic field is gernated by an annularly arranged magnet in the area of the yoke plate and a target space between the target and the substrate is shielded by means of an iron core which also increases the field strength of the variable magnetic field.
摘要:
To prepare essentially water-insoluble, long-chain ammonium polyphosphate, in a first stage, ammonium orthophosphate and phosphorus pentoxide are reacted in the presence of gaseous ammonia in a reactor equipped in its interior with mixing, kneading and comminution apparatus, until the drive motor of the reactor passes through the second current peak in its current consumption/time diagram. In a second stage, the material discharged from the reactor is then fed to a disk dryer, the heating disks of which are maintained at temperatures of 240.degree. to 300.degree. C., whereas its lower cooling disk has temperatures of 5.degree. to 45.degree. C. The material, which covers the disks of the disk dryer at a layer thickness of 5 to 20 mm, has a residence time of 35 to 70 minutes in the disk dryer, while ammonia-containing gas is continuously passed through the disk dryer. Finally, the ammonia-containing gas exiting the disk dryer is freed from water vapor contained therein by condensation and the ammonia-containing gas is reheated prior to its entry into the disk dryer.
摘要:
For producing substantially water-insoluble, chain-type ammonium polyphosphate, equimolar quantities of diammonium phosphate and phosphorus pentoxide are reacted at temperatures from 170.degree. to 350.degree. C. in a zone, which effects continuous mixing, kneading and comminution, in the presence of a stream of ammonia gas. In this process, the water is separated from the ammonia gas which leaves the zone and contains water vapor, and the dried ammonia gas is caused to flow again through the zone.A plant for producing substantially water-insoluble, chain-type ammonium polyphosphate can comprise a reactor (1) into which an ammonia feed pipe (8) and pipes for feeding phosphorus pentoxide (6) and diammonium phosphate (7) lead and from which an ammonium polyphosphate discharge pipe (9) and an exit gas pipe (10) start. The exit gas pipe (10) leads into a condenser (13) which is flow-connected via a pump (14) to a heat exchanger (15). An exit gas line (18) which leads into the ammonia feed pipe (8) starts from the heat exchanger (15).

摘要:
A method for operating a first and a second electrical load or consumer in an alternating current network. The method can be operated in an optional first operating mode, in which the positive and negative half waves for each load are controlled with a first leading edge phase angle. In addition, a second operating mode is provided, in which a first part of the positive and negative half waves for the first load and a second part of the positive and negative half waves for the second load are controlled with respective second leading edge phase angles. Furthermore, a device for performing the method, having first and second leading edge phase-angle control for the first and second loads.
