Abstract: A data cache (16) capable of operation in a write-back (copyback) mode. The data cache design provides a mechanism for making the data cache (16) coherent with memory (26), without writing the entire cache entry to memory (26), thereby reducing bus utilization. Each data cache entry is comprised of three items: data, a tag address, and a mixed size status field. The mixed size status fields provide one bit to indicate the validity of the data cache entry and multiple bits to indicate if the entry contains data that has not been written to memory (26) (dirtiness). Multiple dirty bits provide a data cache controller (14) with sufficient information to minimize the number of memory accesses used to unload a dirty entry. The data cache controller (14) uses the multiple dirty bits to determine the quantity and type of accesses required to write the dirty data to memory (26). The portions of the entry being replaced that are clean (unmodified) are not written to memory (26).

Abstract: For a power turbine which is coupled to a generator and utilises the exhaust gas of a supercharged internal-combustion engine which is not required for supercharging, the invention indicates a control system which makes it possible for an asynchronous generator to be run up directly by the power turbine. Here, the pressure upstream of the power turbine pvT is used as manipulated variable for a device which controls the aperture cross-sections of at least one shut-off element arranged in the exhaust-gas feed line leading to the power turbine and of a bypass valve arranged in a bypass line circumventing the power turbine. During acceleration, the shut-off elements and the bypass valve remain in an intermediate position which guarantees further acceleration of the generator to its rated speed and in which the speed rise dn/dt in the region of the rated speed nN attains a value which is so small that safe connection of the asynchronous generator is guaranteed. <IMAGE>

Abstract: This invention relates generally to surgical tools and particularly to powered microsurgical tools of novel construction. 
     Surgical cutting tools, such as scalpels and saws are well known in the art. A major difficulty with all such tools is that the surgeon must supply the required cutting force by means of a sawing or slicing motion. The surgical cutting tool of the invention is powered by a remote drive means and removes the requirement for the surgeon to provide the cutting force. All the surgeon need do is guide the tool. The tool in its fundamental form consists of a rotatable work wheel (40), i.e., a cutting blade (12) that is mounted at the end of a casing member which in one embodiment includes a rigid tubular section that enables the surgeon to handle it as a conventional scalpel.

Abstract: A control for a moisture sensing assembly, adapted for mounting on the inner surface of a vehicle window or windshield to control vehicle accessories such as windshield wipers, maximizes the window area being sensed in relationship to the size of the assembly and provides immunity to interference from environmental influences. In the preferred embodiment, moisture on the outer window surface (16) is detected by first and second moisture sensors (36, 38, 40, 42, 44, 46) each including infrared energy radiating diodes (40, 42) and radiant energy detectors (44, 46) which detect and process radiant energy to produce a moisture signal that is a function of the moisture on the window. A synchronizing circuit (82) intermittently actuates the radiating diode (40, 42) for the two sensors (36, 38, 40, 42, 44, 46) individually and alternatingly at equally-spaced intervals. The synchronizing circuit (82) also inhibits the radiant energy detectors (44, 46) from processing the radiant energy signal except when the corresponding radiating diodes (40, 42) are emitting energy in order to prevent interference from the other radiating diodes (40, 42) and environmental influences. The synchronizing circuit (82) includes a pair of oscillators (140, 148) which include capacitors (166, 173) and coupling devices that coordinate the discharging of the capacitors (166, 173) in a manner which provides equal intervals between alternating output pulses from the oscillators (140, 148).

Abstract: A rosin modified acrylic resin for use in a toner composition is provided. The resin is prepared by steam stripping a mixture of solution polymerized styrene-acrylic copolymer, rosin, and a suitable solvent, such as toluene or xylene, followed by cooling and grinding to form the styrene acrylic-rosin resin. This binder resin has an inherent positive charge of at least 2.0 in contrast to typical prior art toner binders which are inherently negatively charged. The binder resin is formulated with conven­tional coloring pigments, charge controlling dyes and carriers such as iron powder or glass beads to provide dry toner compositions of high positive charge. As a result of the inherent positive charge of the binder resin, the toner composition of this invention needs much less of an addition of charge control agent to bring the positive charge to the required +10 to +12; thereby leading to far lower manufacturing costs.

Abstract: To remove oil from oil-containing wet mill scale, mill-scale sludge and similar substances, these substances are treated in a continuous furnace (12) combined with an iron-ore sintering plant. Hot cooler exhaust air from the sintering cooler (5) flows in countercurrent to the mill scale through the continuous furnace (12). In this process, the scale is dried and some of the oil is burnt. The cooler exhaust air is then fed with the volatile oils into the ignition furnace (3) of the sintering machine (1) as combustion air and the residual oils are burnt therein. This prevents unburnt oils depositing in the electrostatic filter (8). Dry mill scale freed of oil can be fed to the mixed material (17). <IMAGE>

Abstract: The subject invention relates to an electrostatic dissipative polymeric composition. It has been found that the incorporation of a polyimide into a base polymer will enhance the electrostatic dissipative properties (ESD) of the composition comprising a base polymer and an ESD additive. This enhancement of the ESD properties is illustrated by the decrease in both the surface resistivity and volume resistivity. In compositions employing the same ESD additive this enhancement provided by the incorporation of the polyimide could allow a reduction of electrostatic dissipative additive required to achieve acceptable results. Further, the improved properties could allow the material to be adopted for specific applications that cannot be normally achieved without the enhanced properties.

Abstract: A vibratory plough assembly 201 incorporates a vertical ground parting blade 202 with a front cutting edge 203 and a ripper tooth 208. The blade 202 is bifurcated rearwardly of the cutting edge 203, the blade 202 being formed by two spaced-apart side plates 214. The upper part of the plates 214 constitute a support frame which is pivotally connected by a pin 205 to a base plate 240. Attached rearwardly of the pivot pin 205 and preferably cantilevered beyond the plates 214 is a vibrator unit 232. The vibrator unit 232 when operational provides a vibratory frequency of between 5Hz and 17Hz to the ripper tooth 208 in both a vertical and arcuate path. The pivot pin 205 is preferably located above or forwardly of the cutting edge 203. The base plate 240 and support frame, by virtue of the vibratory unit 232, experience relative movement in the manner of a pair of jaws the mouth of which extends rearwardly. Buffers 252 located between the base plate 240 and the support frame tend to bias the jaws into an open condition. A mounting means 400 enables the assembly 201 to be attached to a tractor vehicle so that in use, a trench is dug by the assembly 201 and cable, which passes from a forward position to a rearward position via cable guides 215 located between the plates 214, can be laid.
