Tack box

Split cycle engine and method in which output power and power density are increased in some embodiments with a turbocharger or supercharger which increases the pressure in the compression cylinder and also increases the power output of the engine without a corresponding decrease in the efficiency of the engine (work done per unit fuel). In other embodiments, the engine is used for braking, and the energy produced by braking is stored pneumatically and then used in driving the compressor.

A fluid coupling 10 for connecting the output of an upper 102 and a lower 101 submersible pump in a well casing 100 to the well supply pipe 105. The fluid coupler 10 includes an upper coupling unit 11 connected to the upper pump 102, a lower coupling unit 12 connected to the lower pump 101, and a manifold unit 13 operatively connecting the upper 11 and lower 12 units together to form a framework which surrounds and suspends the upper pump 102.

Hardware and software improvements in workstations which utilize virtual addressing in multi-user operating systems with write back caches, including operating systems which allow each user to have multiple active processes. In virtual addressing, multi-user workstations, system performance may be improved significantly by including a virtual address write back cache as one of the system elements. Data protection and the reassignment of virtual addresses are supported within such a system as well. Multiple active processes, each with its own virtual address space, and an operating system shared by those processes in a manner which is invisible to user programs. Cache 'Flush' logic is used to remove selected blocks from the virtual cache when virtual addresses are to be reassigned.

Virtual address write back cache with address reassignment and cache

Improvements in workstations which utilizes virtual addressing in multi-user operating systems with write back caches, including operating systems which allow each user to have multiple active processes directed to the support of alias addresses, i.e., two or more virtual addresses which map to the same physical address in real memory Specifically, alias addresses are created so that their low order address bits are identical, modulo the size of the cache (as a minimum) for user programs which use alias addresses generated by the kernel, or wholely within the kernel. For alias addresses in the operating system, rather than user programs, which cannot be made to match in their low order address bits, their pages are assigned as 'Don't Cache' pages in the memory management unit (MMU) employed by workstations which utilize virtual addressing.

Alias address support

Grinding wheels are constructed with an improved type of resin binder of a low molecular weight solid epoxy resin. The epoxy resin is in the form of a fine powder and may be mixed with other wheel components such as abrasive grain, wetting agent and fillers. A method in which the epoxy resin and curing agents are processed from their commercially available forms to that most suitable for use as a grinding wheel binder.
