Abstract: A concrete/cement resurfacing machine integrates a dust collection subsystem and an overlay mixing/distribution subsystem, enabling a single operator to steer the machine to a desired floor location and deposit mixed, cementitious overlay material. The combination of dust collection and overlay mixing saves considerable time and achieves improved results, eliminating the need for separate vacuum machines while reducing the risk that dust will be released as bags of dry ingredients are added to the mixing tank. A single propane engine powers a hydraulic pump, with fluid being routed to three separate hydraulic motors with associated control valves to provide for forward/reverse locomotion, bidirectional paddle mixing, and vacuum generation. The dust collection system is preferably a two-stage system including a vacuum collection tank and a HEPA filter.

Abstract: A compact rotating fluid stabilizer and multiphase separator system separates a multiphase input fluid flow and delivers single phase liquid streams at elevated pressure from inlet conditions. A separator housing with a lower separation chamber and an upper separation chamber rotates about a central axis. The input flow is received into the lower separation chamber and centrifuged into its constituent phases. A gaseous phase migrates through a rotary structured packing up a center tube and exits through a discharge pipe atop the housing. A heavy liquid phase is delivered at high pressure through a first diffuser ring with permeable gas tip seals supplied by high pressure gas. A lighter liquid phase migrates over a weir into an upper separation chamber and is delivered to a second diffuser ring. The compressor reduces vapor pressure to stabilize the light liquid phase.

Abstract: An apparatus is especially suitable for high volume manufacture of a non-dairy frozen dessert. Pre-frozen blocks of ingredient mixture are masticated in a first stage of the apparatus and aerated in a second stage of the apparatus. Compressed air is injected into a masticated slurry produced by the first stage and mixed into the slurry in the second stage. A continuous process transforms the pre-frozen blocks into a masticated, aerated slurry suitable for immediate consumption, storage for later consumption, or processing into bars or other forms. This apparatus and process is suitable for some ingredient mixtures for which a scrape surface heat exchanger apparatus and process are not suitable.
