  • Publication number: 20190177658
    Abstract: The present invention relates to novel cleaning compositions that are substantially free of cocamide diethanolamine. In an aspect of the invention, the compositions utilize a surfactant system and coupling agents as a replacement for the rheology modifier cocamide diethanolamine. The combination of a surfactant system and coupling agents can be used as a replacement for traditional rheology modifiers and foaming agents which are under regulatory pressure while providing concentrated liquid cleaning compositions with a viscosity of 400 cps or less. In another aspect the invention relates to novel cleaning compositions such as pot and pan soaking compositions, dishwashing compositions, food and beverage foaming cleaners, vehicle cleaning and the like suitable for use in hard water, which can be solid or liquid. The invention further relates to methods of making these compositions, and to methods employing these compositions.

  • Patent number: 5446496
    Abstract: A frame rate conversion system synchronizes data transfers to and from a VRAM frame buffer which are concurrent, continuous, and asynchronous. The system comprises a frame buffer having a split memory for communicating data to a split output shift register. A frame buffer control supervises writing operations to the split memory at a first frame rate. A display control supervises reading operations from the shift register at a second frame rate which is slower than the first frame rate. The frame buffer control and the display control communicate control signals through double synchronizers. The display control has a counter for counting frames of data which have been read from the VRAM frame buffer. The display control prevents the writing of a frame into the split memory after a particular number of frames has been counted so as to prevent the frame buffer control from writing over and destroying existing data which has not yet been read from the split memory by the display control.

  • Patent number: 5293593
    Abstract: A method and apparatus for use in read/write operations by a processor that reads and writes information in first and second address formats. The method and apparatus include a memory and a memory mapper for remapping according to a predetermined scheme those memory fragments not containing information stored in the first address format. Memory fragments are thus accessible to the processor for reading and writing information in the second address format. Such remapping operation results in the memory fragments appearing logically contiguous. In the preferred embodiment, the first address format is an x-y address format and the second address format is a linearly addressable format. An alternative embodiment discloses the use of a second memory for reading and writing information in the second address format. In that embodiment, the memory mapper remaps the memory fragments to appear logically contiguous with said second memory.
