Title: Способ определения параметров потока
Inventor: GALKIN VLADIMIR I
IPC: G01P5/24
Filed: 1992-06-26
Granted: 1995-02-27
Abstract: Изобретение относится к способам определения температуры, скорости, направления и других параметров потока, в частности потока газа. Цель - исключение влияния задержек сигналов и их изменений в электрических цепях на результаты определения степени ослабления и времени прохождения акустического сигнала через исследуемый поток. С помощью ультразвукового излучателя формируют короткий акустический сигнал, пропускают его через поток под различными углами к его направлению, принимают и преобразуют его в информационный электрический сигнал. По электрическому сигналу, возбуждающему ультразвуковой излучатель, формируют опорный электрический сигнал. Первые импульсы опорного и информационного электрических сигналов сравнивают с заданными пороговыми уровнями, не превышающими их пиковых величин, измеряют длительности этих импульсов на уровне заданных пороговых значений, измеряют временной интервал между первыми импульсами информационного и опорного сигналов в момент достижения ими пороговых значений. О времени распространения акустического сигнала в исследуемом потоке судят по временному интервалу между положениями экстремумов первых импульсов информационного и опорного электрических сигналов, который определяют из соотношения: T = T и + (A·t 2 -B·t 1 ) , где T - время распространения акустического сигнала в потоке; T и  значение временного интервала между первыми импульсами информационного и опорного сигналов в момент достижения ими пороговых значений; A - коэффициент, зависящий от формы первого импульса информационного сигнала; B - коэффициент, зависящий от формы первых импульсов соответственно опорного и информационного сигналов. По измеренной длительности первого импульса информационного сигнала на нескольких пороговых уровнях определяют степень ослабления акустического сигнала потоком в данных циклах измерений. Используя определенные данным способом время прохождения акустического сигнала через поток и степень его ослабления, по известным соотношениям определяют параметры исследуемого потока. 3 ил.

Granted: 1996-05-10
Abstract: FIELD: production of adhesives. SUBSTANCE: carbamide is condensed with formaldehyde, the process is carried out by heating in aqueous medium having variable pH, molar ratio of formaldehyde and carbamide being (1.6:1):(2.2: 1). Said condensation takes place by mixing 35-55 % aqueous formalin solution or aqueous solution of carbamide-formaldehyde concentrate (content of formaldehyde and carbamide in said concentrate being 45-65 % and 15-25 % respectively) with carbamide. This process is initially carried out at pH 6.0-8.5 and 20-80 C within 0.5-10 h. Then pH is decreased to 3.5-5.5, temperature being elevated from 70 C to boiling point and condensation takes place to viscosity 15-1000 mPa c . Then pH is brought up to 7.0-9.0 and carbamide is added into thus prepared precondensate till molar ratio of formaldehyde and carbamide is (1.6: 1): (1.2:1). Further condensation is carried out within 0.5-2 h at 60-80 C. The process is followed by decreasing temperature to 0-35 C. Evaporation stage may be carried out till content of dry material is 60-70 %. Said process may take place after preparing of reaction mixture or after producing precondensate or after condensation of said precondensate. EFFECT: improves efficiency of method. 2 cl, 2 tbl

Title: Device for operating windscreen wiper
Inventor: PIENTKA RAINER DIPL ING
IPC: B60S1/08
Filed: 1995-05-27
Granted: 1996-07-11
Abstract: The invention relates to a device for operating a windscreen wiper with a sensor device (10) to detect the degree of wetting of a windscreen, with an evaluation unit (20) and a control unit (30) for the wiper which is controlled by the evaluation unit (20). The analysis of the degree of wetting of the windscreen is improved in that the evaluation unit (20) has a recognition stage for decreasing moisture on the windscreen by means of which it is possible to determine a rising level (SP) in the measurements (MW) as a result of the drying process from a time sequence of measurements (MW) obtained from the sensor signal (S). Unnecessary wiping operations can thus be prevented.

Title: Two sets of tufting needles for textile application
Inventor: JUNGBECKER CHRISTIAN
IPC: D05C15/20

Granted: 1996-11-07
Abstract: In a pairing of first and second tufting needles (6, 13; 18, 23) for use in three-shafted tufting, wherein the first and second tufting needles (6, 13; 18, 23) can by means of their pistons be directly or indirectly secured to a needle bar (1, 10; 25, 26) of a tufting machine, in each case forming a row, and wherein at least the shanks of all these tufting needles (6, 13; 18, 23) run parallel to one another, the invention provides that when the two needles bars are moved one upon the other, these shanks can move into a common needle row, thus making it possible to create additional pattern effects in tufting. The first tufting needles (6, 13; 18, 23) then, can be straight, while the second tufting needles (6, 13; 18, 23) have an offset parallel shank due to crimping away from the piston of these tufting needles (6, 13; 18, 23) - and so when mounted, towards the first tufting needles (6, 13; 18, 23). However, it is also possible that both the first and the second tufting needles (6, 13; 18, 23) have offset parallel shanks crimped away from the pistons of these tufting needles (6, 13; 18, 23) - and so when mounted, toward the corresponding tufting needles (6, 13; 18, 23). Further, the first tufting needles (6, 13; 18, 23) can be straight, while with the second tufting needles (6, 13; 18, 23) the shank forms an angle of 70-110 DEG .

Granted: 2000-12-21
Abstract: A diaphragm for an electroacoustic transducer has a) a core layer containing poly(meth)acrylimide foam and b) at least one cover layer. The diaphragm is produced by laminating the cover layer with the core layer, using a pressure of 0.4 MPa and a temperature of 160° C., whereby at least the side of the core layer which comes into contact with the cover layer is compressed. The resultant composite is subsequently cooled to a temperature below 80° C., before the pressure is reduced to the ambient pressure. The process can be carried out as a single-step process. The diaphragms produced by this process demonstrate an excellent stability, whereby the cover layers in particular are highly resistant to separation.
