Patent EP-0366000-A2 (EP)
Inventor: HACK JOACHIM
IPC: G11B19/04
Filed: 1989-10-19
Abstract: In information storage devices, for example in magnetic storage devices with magnetic discs, in particular with flexible media, when predetermined maximum waiting times of the magnetic heads on the same magnetic track are reached, the magnetic heads are moved away according to a predetermined control scheme from the waiting magnetic tracks, possibly into alternate areas of the magnetic surface, and are then returned to the waiting position. In information stores which can be read out by means of a laser beam, in which the information is stored optically or magneto-optically, positioning of the laser beam away from the working tracks into an alternate position is likewise advantageous.

Abstract: Application programs compiled for a first, "source", computer are translated, from their object form, for execution on a second, "target", computer. The translated application programs are linked or otherwise bound with a translation of the source computer system software. The translated system software operates on the image of the source computer address space in the target computer exactly as it did in the source computer. The semantics of the source computer system software are thus preserved identically. In addition, a virtual hardware environment is provided in the target computer to manage events and to deal with differences in the address space layouts between the source and target computers.

Abstract: A method of manufacturing a cutter assembly for a rotary drill bit includes the step of bonding to a carrier (10) a cutting element (12) which comprises a thin hard facing layer (13) already bonded to a less hard backing layer (14), the backing layer having a greater coefficient of thermal expansion than the hard facing layer. In order to compensate for convex deformation of the rear surface of the backing layer, when the cutting element is heated during the bonding process, the rear surface (15) is made initially concave at ambient temperature. Alternatively, or additionally, the co-operating surface (18) of the carrier may be concave.

Abstract: This relates to a closure combination which includes the closure being formed with a sealant channel (20) to which there is applied by spin lining a plastisol type compound sealant (10), or the like. It is preferred, from an economy standpoint, to utilize a minimal amount of the sealant while providing the necessary sealing surface between a container neck finish and the sealant. Since the sealant is applied by a spin lining process during which the closure (12) is (30) rapidly rotated, the sealant is thrown radially outwardly by centrifugal force. However, the viscosity of the sealant normally is such as to prevent it from being returned to a level-flat condition. It has been found that by modifying the sealant channel (36) configuration, particularly the slope of the base wall (34) thereof, depending upon the viscosity of the sealant, one can selectively obtain a uniform thickness sealant application or a flat top sealant application. Further, by sloping (72) the end seal (70) surface of the container to which the closure combination is to be applied, one can obtain extra beneficial results. It is also desirable to provide a dam (40) arrangement for the sealant which permits return overflow of the sealant with the dam accommodating the overflowing sealant (42).

Abstract: This invention relates to coated abrasive products having a pressure-sensitive adhesive layer coatable from water. Many coated abrasive products, especially coated abrasive sheets and discs, are mounted on a support pad, sometimes called a back-up pad, during use. One means for securing the coated abrasive article to the support pad calls for a pressure-sensitive adhesive. Typically, the surface of the coated abrasive article not containing the abrasive grains will bear a layer of pressure-sensitive adhesive. For many years, pressure-sensitive adhesives have been coated from organic solvent solutions onto the non-abrasive side of the coated abrasive article with excellent results. However, because recent governmental regulations require reductions in solvent emissions, the coated abrasive industry desires to eliminate all organic solvents from their coating operations. This invention provides a coated abrasive product having a backing bearing abrasive grains on one major surface thereof and a pressure-sensitive adhesive, coatable from water, on the other major surface thereof. The pressure-sensitive adhesive can be used to secure the coated abrasive to a support pad or back-up pad. The support pad provides the coated abrasive with the necessary foundation during abrading operations. The pressure-sensitive adhesives of this invention can adequately secure the coated abrasive to the support pad even at high rotation speeds and at high grinding pressures. Previously known pressure-sensitive adhesives for coated abrasives that are coatable from water were unable to provide this property.

Abstract: In circuit card test devices, a television camera is used to take a plurality of pictures of the circuit card to be tested, the incidence of light being varied with each picture, so that a plurality of pictures arise from the same circuit card, which have different shadow regions that are caused by the components mounted on the circuit card. Conclusions can be reached on the size and position of the components from the size, the position and the shape of the shadows. Such a test device requires the specification of an illumination device with which the test object can be illuminated from various directions, an arrangement being required which is largely free from wear. This is achieved according to the invention when the light of a light source is fed directly into a plurality of optical fibres, these optical fibres containing optical valves which can be switched by electrical control signals into an optically transparent or opaque state, so that the illumination of the circuit card is performed by one or more selected optical fibres. <IMAGE>
