Inventor: JENNY RUDOLF
IPC: B65H61/00
Filed: 1987-03-07
Abstract: Die Spulgeschwindigkeit beim Umspulen eines Fadens wird zur Steigerung der Produktionsleistung derart eingestellt, dass die Fadenspannung jeweils möglichst knapp unterhalb eines Werts liegt, oberhalb dessen Fadenbrüche häufiger auftreten. Vorzugsweise wird die Umspulgeschwindigkeit in Abhängigkeit von der sich auf einer Vorlage (1) noch befindlichen Restfadenlänge programmgemäss geändert, wobei die Restfadenlänge aus der Differenz zwischen der totalen Länge des Fadens auf der Vorlage und der bereits von der Vorlage abgespulten Länge des Fadens ermittelt wird. Die totale Länge des Fadens auf einer Vorlage wird aus dem Gewicht des vorgelegten Fadens und einem Kalkulationsfaktor Länge pro Fadengewicht berechnet. Zu diesem Zweck enthält die Einrichtung zur Durchführung dieses Verfahrens eine Wägezelle (12), die an die Steuereinheit (8) der Umspuleinrichtung angeschlossen ist. Die Umspulgeschwindigkeit kann während des gesamten Umspulprozesses nahe an jener Grenze gehalten werden, hinter der Fadenbrüche vermehrt auftreten.

Abstract: In an information processing system having a paging mechanism in which a part of a memory address space of a CPU (110) is used as a page frame (90) and an expanded memory is accessed through this page frame (90), the size of the expanded memory of the system is checked upon initialization of the system, and an expanded memory set register (200, 202, ...) provided for each memory set (130, 132, ...) constituting the expanded memory is controlled on the basis of the check result, thereby preventing the CPU from accessing a specified memory set. The same I/O port addresses of the register (211, 221, ...) concerning the paging mechanism are pre­vented from being present in both the standard internal expanded memory (300) and an external expanded memory (400).

Abstract: The invention concerns a procedure for the bleaching of pulp using oxygen as an oxidating bleaching chemical. The essen­tial features of the invention are that oxygen is used in the first oxidation stage of the bleaching process, that the pulp is subjected to enzyme treatment, and that after oxygen bleaching and enzyme treatment, the pulp is washed. According to the invention, the subsequent oxidation stages can be implemented using bleaching chemicals containing chlorine, e.g. chlorine gas and/or chlorine dioxide. The use of enzymes allows partial burning of the washings and enables the amounts of toxic compounds in the spent bleach liquor to be reduced, simultaneously lowering its chemical oxygen demand.

Abstract: An orthotic footwear insert (11) is made of a resilient shock-ab­sorbing layer (12). The layer has an upper surface (27), intended to receive the heel, the upper surface having a plurality of outwardly pro­jecting nodules (21) arranged in a waffle-like pattern which defines the upper plane. The layer also has a lower surface, beneath the heel-­receiving surface. The lower surface has a plurality of rib members extending longitudinally between the back and front edges (15, 17)) and generally parallel to the side edges (13) of the layer. The rib members are therefore arranged such that air does not become trapped between them when pressure is applied to the layer. The invention also includes a method of making a shock-absorbing composition, which can be used to con­struct the footwear insert or other products. The composition is extremely strong and resilient, and can be formed into virtually any shape. Thus, the composition is not limited to use in footwear, but can be used in any application requiring resiliency and shock-absorbency.

Abstract: A display panel formed by arranging a plurality of picture cells in a XY matrix form. In each picture cell, a plurality ofstripe-shapedself luminous pixel elements are formed on a display screen of a tube envelope in a predetermined pitch so that their longitudinal directions are directed in the horizontal direction of the display screen. Thus, a large screen display apparatus can be made, in which a bonded portion between adjacent picture cells can be made inconspicuous. Also, a range of visual field relative to a predetermined distance from the display screen can be enlarged and the function of large screen can be sufficiently demonstrated. A cathode ray tube is also provided, in which a stepped portion is provided on the peripheral edge portion of a flat panel having a fluorescent screen formed on its inner surface, and a funnel portion is bonded to this stepped portion. Therefore, strength and dielectric strength of a tube envelope can be increased, and a visual field of picture screen can be enlarged. Further, in this cathode ray tube, the thickness of the funnel at its portion where the funnel and the panel are bonded is reduced, whereby the screen side wall portion of the tube envelope can be reduced in thickness. Furthermore, in a large screen display apparatus in which the above cathode ray tubes are arranged in a XY matrix-fashion, the stepped portion of the peripheral edge portion of the flat panel is provided outside of a line connecting the fluorescent element adjacent to the stepped portion and the end portion of the flat panel. Thus, the bonded portion can be made inconspicuous and an image of high quality and a wide visual field can be obtained.

Abstract: A noise reduction circuit comprises a high-pass filter (34) for extracting a signal component containing noise from an input signal, a variable level limiter (35) for limiting the level of the signal component extracted by the filter (34) to produce a noise suppressing signal, and a level adjuster (44) for adjusting the level of the noise suppressing signal. A level detector (46) detects the level of the input signal, and a control signal generator (47) generates first and second control signals based on the detected output of the level detector (46), supplies the first control signal to the level limiter (35) so as to control the limit level thereof, and supplies the second control signal to the level adjuster (44) so as to control the gain thereof. In a signal subtracter (33), the noise suppressing signal from the level adjuster (44) is added with reversed polarity to the input signal to suppress the noise contained in the input signal and thereby produce a low-noise output signal.

The invention also provides the means to generate the commands necessary to accomplish this motion, by providing specific steering and drive information such as angle and speed to the mobile robot or AGV¹. The invention accomplishes these tasks in response to direct commands from a stationary controller as well as in response to continuous node-by-node position updates provided by an external navigation system, such as a visual navigation system, or an internal dead-reckoning navigation system, or both.

Abstract: A control method for providing an acceptable motion window (range) that restricts high accelerations and velocities of an ink jet print head (5). The method provides two limited step ranges (28, 30) that are initiated dependent on the total distance that the print head is to be moved. If the distance is outside of the window range, a first step (28, 30) is used to bring the print head to a position which is a fixed second step (36) from the final position. By limiting the print head's motion in each step range, the excitation of the fluid (ink) system (8 and 11) is limited. With the first step completed (28 or 30), a second step range (34 or 36) is used to drive the print head to the final position. If the initial distance is within the window range (32), the first step range (28 or 30) is selected to drive the print head (5). The method is implemented with a computer program (FIG. 3) and print head position signals (FROM16).

Abstract: A clock recovery circuit (20) utilizes a Voltage Controlled Oscillator (VCO) (19) having a base frequency which is substantially equal to or slightly less than the rate of a data input signal which allows for very high frequency systems which require data synchronization. A D Flip-Flop (15) provides phase comparison between a recovered clock signal and an incoming data signal, and produces an error signal only when the data signal leads the recovered clock signal. The error signal determines the amount of shift necessary to cause the timing of the recovered clock signal to equal that of the data signal. If the recovered clock signal leads the data signal, the absence of the error signal will cause the recovered clock signal to fall back to its base frequency which is guaranteed to be slightly less than the frequency of the data signal. The clock recovery circuit is only required to make timing adjustments in one direction which greatly simplifies the required circuitry.
