  • Publication number: 20230173122
    Abstract: A bulk HPP container (10) includes a flexible body portion (12) having closed off ends (14), at least one of which is depicted as being recessed to enable the containers (10) to be positioned end-to-end in an efficient manner, for example, when placed into an HPP pressure vessel, such as a wire wound vessel. One or more openings are provided in the body portion of the container with n appropriate closure for pumpable product to enter and exit the container. In this regard, an inlet valve (16) or other type of closure may be located at the opening in one or both of the ends of the container. Also, one or more outlet valves (18) or other type of closure are located at an opening on the body portion (12) of the container for emptying the container, for example, after HPP. The body portion 12) is composed of sufficient flexural strength and sufficient flexural modulus to enable the container to reduce in volume by from 0 to at least 30% while being rigid enough for reuse over a desired number of HPP cycles.

  • Publication number: 20230114240
    Abstract: A container or load basket (80, 90) constructed for addressing thermal stratification of a product in the container/load basket and addressing thermal stratification of the processing medium during high pressure processing with a pressurized processing medium. The container includes an upper section (86, 96) forming a volume for receiving the product to be processed and a truncated lower section forming the bottom of the container. The bottom of the container is defined by a floor or partition (84, 92) extending across the lower portion of the container.The floor or partition can be constructed from the same material from which the upper section of the container is formed or a material that is more adiabatically active than the material from which the upper section of the container is formed.

  • Patent number: 5284227
    Abstract: A disc brake assembly having enhanced brake efficiency and improved cooling includes a brake pad having arcuate upper and lower edges and a width that diminishes along its length from its leading edge to its trailing edge. A braking force is exerted on the brake pad by plural hydraulic actuators having pistons aligned with longitudinally spaced portions of the brake pad. The radial and circumferential locations of such portions are selected to minimize differences in the radial wear of the brake pad. The actuators are preferably symmetrically positioned with respect to a brake rotor centerline but may be positioned asymmetrically. The actuator pistons are confined for movement within close tolerances in order to limit the angle though which the brake pads can rock.

  • Patent number: 5259483
    Abstract: A low profile disk brake caliper in which a disk brake pad is mounted on a flexible diaphragm contained within a piston cavity. Pressurization of the piston cavity by a master cylinder expands the diaphragm and urges the brake pad sidewardly from the housing to engage an adjacent rotor. In the preferred embodiment, the diaphragm is received within a cap seal slidably mounted within the cavity, and the brake pad is mounted removably within a pad carrier attached to the cap. A backing seal is positioned adjacent to the underside of the top wall of the diaphragm and is clamped against the cap by assembly bolts, so that the top wall of the diaphragm is compressed between the cap and backing seal, thereby preventing the top wall from bulging outwardly when the cavity is pressurized. The housing is mounted on the hub of a bicycle front wheel and includes a set screw positioned for camming engagement against the front fork to prevent rotation of the brake caliper relative to the fork.
