Abstract: A core holder is described which shows a rock core in a resilient sleeve within a hollow housing. A longitudinal axial force is applied on the core independently of pressure applied radially on the core. Fluid pressure or flow is measured at the periphery of the core during injection of fluids therethrough while various pressures are independently applied at infinitely variable degrees of radial and longitudinal axial forces.

Abstract: This concerns a core holder for a rock core in a resilient sleeve within a hollow housing. Longitudinal and radial forces are applied to the core. Fluid samples can be obtained at selected points along the length around the diameter of the core during injection of fluids therethrough. It concerns a special stem and seal for providing fluid or gas communication from within the resilient sleeve and the exterior of the housing.

Abstract: Vacuum pneumatic conveying apparatus and method are utilized to transfer food products, such as fish, from a boat to a processing factory directly or via a tender vessel. Fish products such as salmon, are withdrawn from a fishing boat through an intake nozzle of a pneumatic vacuum system and entrained in an air flow, upwardly through inlet or receiving conduits of a vacuum, pneumatic, conveying system, and on through a product separator of an in line assembly of an upper product separator and a lower liquid separator. Salmon continue on flying out of the product separator and commence their downwardly momentum and gravity induced travel through discharge conduits, encompassing essentially non flowing air maintained under continuing vacuum.
