Abstract: Bei einem Kreuzspuldrehmagnetmeßwerk mit einem als Wikkelkörper ausgebildeten annähernd zylindrischen Kern sind eine erste und eine zweite Spule übereinander gekreuzt aufgewickelt. Die zweite Spule ist im Bereich der Stirnseiten des Wickelkörpers zwangsläufig über der ersten Spule angeordnet und weist somit eine größere Windungshöhe als diese auf. In dem Kern ist ferner ein Drehmagnet gelagert, dessen Zeigerwelle aus einem Ansatz des Kerns herausgeführt ist. Um die Linearitätsfehler dieses Meßwerks herabzusetzen und eine Anzeige über mehrere Quadranten zu ermöglichen, sind an dem Kern abstandshaltende Mittel angeordnet, welche Windungen der Spule im Abstand zum Ansatz des Kerns um diesen in jeweils einer rechtwinkligen Ebene führen. In Verbindung damit ist der Kern im Wickelbereich der ersten Spule mit einem vergrösserten Durchmesser gestaltet, der in Beziehung zu dem Durchmesser des Wickelbereichs der zweiten Spule so bemessen ist, daß die mittleren Windungslängen beider Spulen angepaßt sind.

Abstract: A method of producing sheets of crystalline material, wherein a growth mask (32, 34) is formed upon a substrate (10) so as to expose selected areas of the substrate through the mask and crystalline material is grown at areas of the substrate (10) exposed through the mask and laterally over the surface of the mask to form a sheet of crystalline material (18). This sheet (18) is separated from the substrate so that the substrate can be reused. To assist separation and ensure the plane of separation does not wander, the substrate or mask are configured to weaken the bonding of the crystalline material thereto. For example, the substrate is scalloped and all but its peaks are covered with the mask, or the mask has a rough surface to ensure voids form between the mask and the crystalline sheet grown thereover.

Abstract: A multimode scrambling system for video signal transmission systems is described. The system provides for baseband video scrambling controlled by a central originating computer facility. The scrambling of each field of a video changes on a per field basis. The video signal is scrambled in several modes including vertical interval scrambling, alternate line inversion, bogus sync pulse generation, video compression and video offset techniques. A scrambling sequence is sent by a unique algorithm, sent during the vertical interval to each system decoder. The algorithm is reordered for each of a plurality of fields of the video signal and the reordering position is identified by a unique synchronization pulse transmitted during the vertical interval of the video signal. Additional security measures are provided to inhibit a subscriber from avoiding a transmitted disable command, or an attempt to invade the subscriber decoder mechanical packaging security.

Abstract: A digital video generator provides for smooth scrolling of a video image across a video display device. A digital memory contains data to be displayed. Under control of a computer this data is transferred to a display memory as needed. The data is displayed with a gray scale intensity level for each pixel. Two successive pixels in the direction of movement are read out of the display memory, a current pixel and a next pixel, and are added together in a mixer with a weighting factor determined by the computer according to the scrolling speed selected to provide a weighted pixel. The weighted pixel is converted into analog video data for display. At intervals depending upon the selected scrolling speed the computer reloads the display memory from the digital memory to replace the data which has been displayed and scrolled off the monitor. Initial values for the top of the display field and the weighting factor are computed each display cycle. The result isthe appearance of smooth partial pixel movementfor each display cycle.

Abstract: A controller for a voice coil motor driven disk file actuator (10) is described. The device has an online adjustable gain characteristic for controlling movement of the actuator assembly and an estimator (56) that estimates actuator velocity and bias. Forward gain is estimated from position and coil current measurements and compared with a nominal value to create an error signal used to adjust the controller and estimator gain characteristics. The control technique allows changes in the open loop system without changing the closed loop performance. By monitoring loop gain it is possible to alter compensator gains to maintain a constant closed loop performance.

Abstract: A shortened tampon applicator (108) of the telescoping tube type employs an ejector tube (126) to store a tampon (140) it its distal end (112) and an outer tube (110) disposed by a slip fit thereover to thus shorten the overall length of the tampon and applicator (108) assembly. 
Directionally-locking inward flaps (122) fixed within the distal (112) end of said outer tube (110) engage the distal end (112) of the tampon (140) stored in the ejector tube (126) thus securing the latter relative to said outer tube (110) while permitting only distal expulsion therefrom. The ejector tube (126) preferably has inwardly biased flexible portions at its distal end (128) which serve to catch behind the proximal end of the tampon (140). In the preferred version, the inwardly biased portions are unique undulations at the blunt distal end (128) of the ejector tube (126) which advantageously cooperatively functions with a tampon (140) having an enlarged tail.

Abstract: A method for traversal of primitives in a graphics display system includes calculating pick data for a predetermined primitive, testing the primitive for invisibility, exiting to a next graphics order if the invisibility step is positive, testing the primitive for detectability, exiting to a next graphics order if the detectability test is false when traversal is performed for pick correlation purposes, determining whether a transformation environment update is required, recalculating the transformation environment if required, binding display attributes for the primitive and processing subsequent graphics orders to draw the primitive. Also, to eliminate unnecessary storing of registers when an execute structure is processed, a number of registers are set aside for storing control flags to selectively store registers into the stack. If a flag pick is zero the contents of the corresponding register will be stored on the stack. If the contents of the flag are one, indicating that the contents of the corresponding register has been stored on the stack, the contents will not be stored again, thus saving time and execution of the traversal.
