Patent EP-0331612-A2 (EP)
Inventor: PLESCHIUTSCHNIGG FRITZ-PETER D
IPC: B22D11/16
Filed: 1989-01-23
Abstract: Molten metal is introduced into a tubular mold and is withdrawn from the mold in the partly solidified state. There is included a sensor to measure the behavior of the metal strand as close as possible to the mold in order to control or regulate the drive unit for the withdrawal of the strand on a continuous casting machine. For a more precise determination of the actual conditions, the movement of the strand is measured in an area close as possible to the point where the strand leaves the mold. The measurement of the movement may be made in a non-contact and non-delayed manner by the sensor which responds to radiation. The sensor is designed and positioned so that it produces an evaluatable measurement signal in response to the displacement-time behavior of the strand. The measurement signal is transmitted to a display unit and/or evaluation unit for adjustment of the drive unit in order to obtain the desired speed of withdrawal.

Abstract: The present invention concerns high purity polyether (PEG) polyol compositions and, preferably, polyethylene glycol (PEG) compositions which are useful to provide low calorie food for those who wish to control their tendency to be overweight. A process for the purification of polyethylene glycol through cation and anion ion exchange resins is known. However, this process does not remove the PEG oligomers. The present process comprises subjecting the polyether polyol compositions to membrane filtration to remove substantially all of the impurities, leaving only less than about 10 parts per million of the low molecular weight oligomers in the polyether polyol composition.

Abstract: In an improved process for hot-rolling of seamless tubes with preliminary diameter reduction of the semifinished products (axially pierced round blanks), the coreless reduction step (without mandrel) occurs immediately before the step of continuous rolling on a mandrel and practically at the same time of driving the mandrel into the pierced blank, without interferences therebetween. The apparatus carrying out this operation is positioned immediately upstream of the continuous mill with mandrel, so as to form with this a single unit on the same line, thus reducing the need for room, the operation time and consequently the blank cooling before rolling, whereby the last stand of the rolling mill is reached at a sufficient temperature for rolling without any need of intermediate heating steps.

Abstract: An optical polarization meter measures completely the polarization of a light beam by splitting it into four beams, passing three of the beams through optical elements, measuring the transmitted intensity of all four beams by means of electronic sensors, and calculating the Stokes parameters from the results. One of the optical elements is a horizontal linear polarizer, the second is a linear polarizer with a polarization direction oriented at a 45 degree angle about the optic axis relative to the first, and the third element is a circular polarizer. The measurement of the fourth beam provides a normalizing factor proportional to the incident total intensity that enables one to determine all four Stokes parameters, i.e. the complete state of polarization. This determination is done electronically. The input beam enters the device through a single-mode optical fiber that acts as a spatial filter which, together with other optical elements, controls the position and alignment of the beams through the device.

Abstract: A method and apparatus for segmenting character images in an optical recognition system wherein the character images represent an amount field. The segmentation is accomplished by identifying contiguous areas of black, representing connected portions or lines. The system attempts to recognize the contiguous areas, and if this is not successful either combines (50) an area of contiguous black with an adjacent (but separate) second contiguous black area or separates (64) the contiguous area into two regions and then tries to recognize them. A set of rules is provided which includes discarding fraction bars, material under the fraction bars (such as the numeral "100") and other techniques to isolate the image of the individual amount numerals and decimal from extraneous material to allow for recognition processing or operator entry of the amount into a memory associated with the document.

Abstract: For applying ferroelectrics to electronic devices, the poling treatment of the ferroelectrics has been necessary in order to uniform directions of spontaneous polarizations, Ps, in each ferroelectric. This treatment brings about (1) low yields of the devices, (2) difficulties in the fabrication of array devices, and (3) difficulties in the formation of ferroelectric films on semiconductor devices. 
     Now it has been found that a self-polarized film in which spontaneous polarizations, Ps, are unidirectional can be formed by sputtering a ferroelectric materials containing lead under such conditions that the orientation of Ps will be controlled without poling treatment and a high-performance ferroelectric device can be obtained in a high yield by using this film, and thus a porcess for producing such devices has been found.

A linear rotation of the operating knob of the potentiometer (5) thus produces a linear rising or decreasing of the volume output by the loudspeaker. The direction of rotation and the zero point of the potentiometer (5) can be reversed by means of a change-over switch (7), the amplifier characteristic remaining the same in relation to the rotation of the potentiometer (5). <IMAGE>

Abstract: The spreader roll bearing seal is designed such that return of the centrifuged oil into the oil sump is guaranteed when the spreader roll is stationary, with simple production and assembly. To this end, the O-ring or rings is or are inserted into a sealing ring resting directly on the roll bearing, whose inner surface is provided with a circumferential, undercut profile. The undercut profile may have any desired shape seen in cross-section, advantageously an arc or step shape. As a result of the undercut profile, the oil flow is interrupted and the oil which has been centrifuged out of the lubricating grease is prevented from flowing out when the spreader roll is stationary. The oil which has been centrifuged out is, rather, returned to the oil sump. <IMAGE>
