Abstract: When an access from a virtual machine to a VGA is detected, a table managing identification information of a bridge on each path from a CPU to each VGA and passage setting information indicating whether or not to permit the passage of each path is referred to, and table information and a state of each bridge are set such that the passage of the path from the CPU to an SVGA to be accessed by the corresponding virtual machine is permitted, and the access is executed. Therefore, collision of I/O addresses can be avoided while maintaining the state of connecting a plurality of VGAs with fixed I/O addresses to a plurality of virtual machines.

Abstract: A process for machining a blank from all directions with a machine tool, such as a milling machine, involves the machining from all directions being based on a three-dimensional template. In a first step, the three-dimensional form and, if need be, also the surface finish of the three-dimensional template may be automatically measured, and the associated data may be saved. In a second step, a blank may be held by at least one clamping adapter and a first region is brought into its final, ready to use partial form by the machine tool or the milling machine using said data for numerical control. In a third step, the partially machined blank may be held by at least one clamping adapter in the first, finally machined region and the remaining region may be brought into its final, ready to use overall form by the same machine tool or milling machine.

Abstract: In a virtual machine (VM) environment, a virtual machine ID (VMID) uniquely associated with a preferred virtual guest (222) is sent to a storage controller (108) along with requests to RESERVE or RELEASE a direct access storage device (DASD) (128). The VMID is used by the storage controller (108) along with a path group ID (PGID) to determine the scope of the RESERVE or RELEASE. Thus, preferred virtual guests (216) of a single host processor (112) may share the DASD while both preserving data integrity and operating with the performance benefits of Input/Output (I/O) Assist. Sharing is similarly provided for tape devices with requests to ASSIGN or UNASSIGN.

Abstract: In executing data processing operations, a data processing system has a physical memory that is divided into a plurality of physical memory zones, each corresponding to a contiguous series of physical page numbers (NPP). A physical memory allocation method, in response to a request from a current process, activates a first function (Resa) which checks the number of available pages in a memory zone that iii distinguished from other memory zones by a name (z) specified by the current process and places the current process in a queue that corresponds to the zone designated (z) if the number of available pages is not sufficient in the zone designated (z), and then activates a second function (Allocate) which extracts a physical page number (NPP) from a list of available pages in the zone identified by the name (z) so that it can be used by the current process.

Abstract: The method described in this disclosure permits the production of dental replacements, such as inlays, onlays, and crowns, at high accuracy of fit and low cost in a single session of the patient's at the dentist's.

In a second processing run a second sensor (7b) and a second processing tool (30b) are used for a fine scan and fine processing. For this purpose the sensors (7a, 7b) and the processing tools (30a, 30b) are all arranged on a single linear stage (13).

Abstract: The preferred embodiment is directed to a lens shaper and finisher which can readily accommodate large sized lens blanks. The preferred embodiment includes a chuck for supporting a lens blank and a lens pattern. A cutter is operably associated with the chuck. A plurality of piston and cylinder assemblies displace the chuck relative to the cutter between a first position wherein the lens blank is removed from the cutter and a second position wherein the lens blank engages the cutter. A control device is operably connected to a least one of the piston and cylinder assemblies to vary the rate at which the lens blank is fed to the cutter. Accordingly, the feed rate may be readily adjusted such that during a rough cutting cycle a lens blank is fed at a slower rate than during a finish cutting cycle to reduce the likelihood of shattering of the lens blank during the cutting process.

Abstract: A method serves for working, by metal-cutting processes, a surface of profiles having a non-circular contour, in particular for grinding camshafts. Starting out from a blank contour (30-1-32), material is removed from the surface to give the profile a desire contour (30a, 31a, 32a) by moving the processing tool and the profile relative to each other in such a manner that the portion of the processing tool which is at any time in engagement with the surface is moved along the contour in a path-controlled manner, while on the other hand the tool is advanced in feed-controlled manner by the surface distance between the blank contour (30,31,32) and the desired contour (30a,31a,32a).

Abstract: The invention relates to an automatic machine for shaping spectacle lenses, especially those in shatterproof material, with a bevel that serves to hold the lens in the frame. Lenses are copied from a pattern by three cutters which correspond to the three types of conventional bevel in current use; a positioning device stations the lens opposite the cutter giving the requisite bevel. Further devices adjust the position of the bevel in relation to the outer edge of the lens, and ensure that it follows the curvature of the individual lens while remaining at the right distance from the edge. The machine is a copier, and as such, utilizes a tracing mechanism for reproduction from the pattern lens; cam control is adopted for scaling the size of the copied lens up or down in relation to the pattern.

Abstract: An arrangement for removing excess material from an object surface, to provide a desired finished surface. Holes are drilled into the object so that the bottoms of the holes lie on the desired finished surface. The holes have a shape so that the observed hole diameter at the prevailing surface of the object is dependent on the hole depth and thereby dependent on the amount of material remaining to be removed between the prevailing surface and the desired finished surface. The prevailing surface is continuously observed and measured, and the depths of material to be removed in a sequence of steps is calculated dependent on the measurements of the prevailing surface and the coordinates of the desired finished surface. As a result of the calculations, the depth of material removed during each step is controlled, so that upon carrying out a sequence of such steps, the surface exposed on the object after the last step has been carried out, coincides with the desired finished surface.

Abstract: Apparatus for making the finishing cut on the internal outline of a rough cut female die has two carriages one sliding in one direction upon the other, and the other carriage sliding upon a base at right angles to the first. A male punch comprising a template of the outline to which the die is to be finish cut is mounted on one carriage and the die or workpiece is mounted in an indexing work holder on the other carriage. The template engages a tracer finger fixed relative to the base and to a hacksaw blade which finish cuts the die or workpiece by strokes with the plane of the blade perpendicular to the die surface being cut. The tracer and blade are in common planes to which one carriage moves perpendicularly and the other parallel. The cutter blade and tracer respectively engage the die or workpiece and punch or template in the same direction so that cutting action urges the template and tracer into engagement.

Abstract: A routing machine for routing a non-linear groove in a flat extensive workpiece having a pattern in the form of a curved rib temporarily secured to the underside thereof. A reference roller in alignment with the routing tool engages a reference surface on the pattern while a cooperating roller is biased against the opposite surface, the rollers being driven so that the pattern is advanced to move the workpiece relative to the tool. The cooperating roller is mounted upon a table which is freely rotatable about the axis of the reference roller so that when the rollers encounter a portion of the pattern which changes direction, the cooperating roller is free to change its orientation with respect to the reference roller thereby enabling the workpiece to retain its initial orientation regardless of changes in direction taken by the pattern.

Abstract: An automatic profile-copying device to be used in conjunction with machine tools of the type wherein a profile carrying the workpieces is caused to advance by being drawn between a pair of rollers between which it is clamped. One of the rollers is coaxial with the working tool of the machine and is driven by a motor operated at an adjustable but constant speed, while the other roller is thrust against the first roller in a substantially elastic manner and is rotated at a variable speed.

Abstract: The machine is designed for the specific purpose of cutting plastic lenses such as acrylic and polycarbonate types. The machine itself includes a table carrying a lens cutter and lens pattern engaging cam in coaxial alignment. A head carrying a plastic lens to be cut and lens pattern in coaxial alignment is coupled to the table for movement towards and away from the axis of the lens cutter and lens pattern engaging cam. The lens cutter engages the periphery of the lens to be cut. The lens pattern defines the finished contour of the lens and engages the cam after a slight radial cut is initially made into the periphery of the lens. Subsequent rotation of the lens and pattern simultaneously results in a cutting of the lens out of the lens material by the lens cutter as opposed to grinding away the periphery of the lens. The machine also incorporates controls for automatically effecting a beveling operation on the lens after the rough cut has been completed.
