Abstract: The development of a nearly-omni-directional pressure probe for three-velocity-component and pressure measurements is described, with particular focus on the techniques and technology employed in probe construction, calibration, electronic interfacing and frequency-response study. The device eliminates the velocity directionality limitations of current multi-hole probes and makes a valuable, rugged tool for use in complex 3-D flow mapping and aerodynamic design and evaluation, in basic research as well as industrial development settings. The probe performance is demonstrated in a flowfield with flow reversal downstream of a backward-facing step. The probe provides low-frequency response capabilities. The probe's main element is a multi-pressure port spherical head, which may include eighteen ports. Fiber optic interferometry techniques may be incorporated to significantly increase frequency response.

Abstract: This invention relates to a cutter apparatus operable to slice a block of cheese or other foodstuffs having a main support assembly with a cutter means mounted thereon. The main support assembly is provided with a rectangular box type structure having an upper top support plate to receive the foodstuffs thereon for a cutting operation. The cutter means includes a plurality, namely four (4), cutter actuator assembly. Each cutter actuator assembly includes a cutter assembly interconnected to a retractable filament assembly. Each cutter assembly includes a cutter filament member connected to an actuator handle member with the filament member being adapted to be pulled laterally from the main support assembly due to the retractable filament assembly. The retractable filament assembly is additionally operable on release of an actuator lever member to provide a biasing force to hold the cutter filament member in an extended position or selectively retract the same within the main support assembly.
