IPC: G06F9/46
Filed: 1990-12-28
Abstract: A digital computer system includes at least one process, an input/output system and an input/output interface or input/output interface program/method. The process generates input/output requests and receives input/output responses. The input/output system performs input/output operations and generates completion notifications in response thereto. The input/output interface or input/output interface program/method generates input/output responses for the process in the order in which the process issued the input/output requests, to reduce the possibility of the process obtaining information from the order in which the input/output system processed input/output requests.

Abstract: In one method of cross-grinding in accordance with the present invention a non-planar surface (12) on a work piece (10), of a non-metallic material having a Vickers hardness value up to 5000, comprises, in each of two grinding steps, traversing the rotational axis of a grinding wheel (30) along a predetermined axis (22), relative to the workpiece surface. In the first step the radially extending plane of the grinding wheel includes the predetermined axis (22), and the required workpiece surface is produced with inevitable ridges. For the second grinding step the deformable working surface of the same, or different, grinding wheel (30) is shaped by a tool (34) capable of shaping in a normal manner the working surface suitable for the first grinding step. However, the working surface of the grinding wheel is altered by the radially extending plane of the wheel when presented to the tool being inclined in one sense at a selected angle (S), in the range 1° to 20°, to the direction of this plane if presented to the tool to obtain the shape suitable for the first grinding step. In the second grinding step the ridges on the workpiece are reduced by the radially extending plane of the wheel with said altered working surface being inclined in said one sense at the selected angle to the orientation of the radially extending plane of the grinding wheel in the first grinding step.

Abstract: A method and apparatus for data management of non-uniform data operates as modules suitable for inclusion into existing applications. The create module is used to create an original data file when an existing application incorporating the create module has output. The access module is used to map the original data file when a second application incorporating the access module requires the original data file for input. The mapping occurs according to a predetermined definition. In one embodiment, the application-specific states used in a first design verification application are mapped to states in a common data set for applications in the design verification application domain. The common data set is one of several common data sets which contain only states which are valid for all applications in the design verification application domain.

Abstract: The press has an eccentric guide (15) in which the eccentric journal (13) runs together with a bearing (14). In contrast with the known eccentric guides, this eccentric guide is not straight but has a curved region (16) on one side. This makes it possible for the ram to cover the greatest part of the stroke during the first 90 DEG  of the rotation of the eccentric shaft and to carry out only a small stroke in the second 90 DEG  of the rotation of the eccentric shaft (10), the deformation of the contact being effected during the later stroke. 
<??>A crimping press having the eccentric guide according to the invention can be more light-weight in construction, be equipped with a smaller reduction gear and requires a small speed of rotation for the drive motor.

Abstract: Conventional turning or milling machines are known in which the drive motor can be coupled via a clutch (9), in particular a trip worm (12/13), to a spindle (15) which moves a tool slide (16). Measuring devices (17, 18) are provided here which measure the actual travel covered by the tool slide (16) and compare it with an input desired travel. The clutch (9) is disengaged when the actual travel corresponds to the desired travel. In order effectively to prevent moving beyond the desired travel, but on the other hand to achieve this desired travel as exactly as possible, a stopping control means (20) is proposed which comprises a speed detector for determining the feed rate of the tool slide and a presetting device which is designed in such a way that the clutch is disengaged for a slowing-down distance, established by a presetting transducer (22) as a function of the feed rate, before the desired travel is reached.

Abstract: In a tone-in-band (TIB) single-sideband-modulated communication system used to communicate digital data:-
     a) In order to compensate for variations due, eg, to doppler shift of the pilot tone in the received signal, during the sweep of the frequency of a local oscillator used to tune the receiver, the output of a narrow band filter is monitored for the presence of the expected pilot tone. When the pilot tone appears to be present, the sweep is interrupted and the error rate of the demodulated digital signal is tested, the sweep being resumed if an excessive error rate is encountered.   b) In order to counter misreception due to co-channel interference, the pilot tone is offset by a small but detectable amount from that used in a co-channel transmission in preparing the TIB transmission either by using a different frequency split-point or by producing the signal in a slightly different part of the channel.

Abstract: A transient optical element is created by providing a body (11) of a third order non-linear material and then passing a pulse of light through the body of non-linear material. The pulse of light has a cross-sectional area corresponding to the cross-sectional area of the transient optical element to be created and power sufficient to induce an index of refraction change over the portion of the body of non-linear material through which it passes. The portion of the body of non-linear material having the induced index of refraction change constitutes the transient optical element with the duration of the transient optical element depending on the response time of the non-linear material and the duration of pulse of light. Typical optical elements that can be so created include prisms, lenses. gratings, mirrors, beamsplitters and wave guides. By forming a plurality of optical elements within the third order non-linear material rather than simply a single optical element, a transient optical circuit can be created.

Abstract: A latching system for latching together two articles is described in relation to the latching of mated electrical connectors, one of which comprises an assembly of connector modules (22). The modules (22) are ganged together side-by-side by the pair of integral spring latch members of the latching system which are secured along commoned end surfaces of the modules (22) to form the assembly into a manipulatable unit. The integral spring latch members include discrete securing sections (76) securable to axial key members (50) within modules (22) near the end surfaces thereof. Forward ends (84) of the spring latch members include latching recesses (100) which latch with projections (152) of the receptacle connector (150), latching the plug assembly to receptacle connector (150) in mated engagement. Gripping sections (110) of spring latch members (70) are deflectable toward each other about fulcrum sections (112), which action deflects free ends (84) outwardly and disengages latching recesses (100) from latching projections (152) to delatch the module assembly from receptacle connector (150) for unmating thereof. The latching projections (152) and latching recesses (100) are especially adapted to continuously engage each other to resist effects of vibration, and to resist inadvertent delatching.

Abstract: A check valve (16) is provided that is especially useful in gas-assisted injection molding wherein pressurized gas is injected into molten plastic material. A tapered or cone-shaped valve member (34) which seats into a correspondingly tapered or cone-shaped valve member (32) provides the means by which the valve seats against reverse flow. Any plastic material entering the gas passageway (24) would contact the base end (46) of the tapered or cone-shaped valve member (34) and not any sealing surfaces (40,42). By minimizing contact with the sealing surfaces, the useful lifetime of the check valve is significantly increased.
