  • Dual key polarity changeable connector
    Patent number: 10725247
    Abstract: Optical fiber connectors configured to allow ease of change of the connector polarity by providing lockable outer housing. In an embodiment, an optical fiber connector comprises an inner housing, at least one key configured to move along the inner housing so as to change a polarity of said optical fiber connector, and an outer housing disposed around at least a portion of the inner housing and configured to slide in a longitudinal direction so as to expose at least a portion of said at least one key, wherein the outer housing includes a flexible portion configured to lock to the inner housing so as to retain the outer housing in a pulled back position relative to the inner housing. A removable alignment key is reattached to the connector to correspond to a first or second polarity.

  • DEHYDRATION BELOW THE TRIPLE POINT OF WATER
    Publication number: 20200200475
    Abstract: A method of drying an organic material by microwave-vacuum drying below but close to the triple point of water has been determined to allow more conversion of microwaves to heat than would occur when microwave freeze-drying at lower pressures. The method comprises introducing the organic material into a microwave-vacuum dehydrator, exposing the organic material to microwave radiation in the dehydrator to dry the organic material by sublimation, and maintaining pressure in the dehydrator in the range of 0.5 Torr to 4.5 Torr. The method provides the benefits of reduced drying time, energy requirements and product temperatures, relative to dehydration done at lower vacuum pressures.

  • Adjustable polarity fiber optic connector assemblies with push-pull tabs
    Patent number: 10663676
    Abstract: Connector assemblies are described herein. For example, a connector assembly including: a housing configured to accept a first ferrule and a second ferrule. The connector assembly may also have a latch component that is removably connected to the housing, wherein the latch component is configured to rotate around the housing. The latch component may have a first locking element configured to engage a second locking element to prevent rotation of the latch component in at least one of a first polarity position to a second polarity position. The connector may further more include a push-pull tab removably connected to the housing and configured to move vertically along the housing when a biasing force is applied in at least one of a forward direction and a rearward direction. Accordingly, the push-pull tab can compress the latch component when moving vertically along the housing.

  • Microwave vacuum-drying of organic materials
    Patent number: 10578359
    Abstract: An apparatus and method for microwave vacuum-drying of organic materials such as food products. The dehydration apparatus (10) has a vacuum chamber (12) with a loading module (14) at one end and a discharge module (22) at the other. The vacuum chamber has access doors (80) spaced between the input end (16) and the discharge end (24) which provide operator and maintenance access. Microwave generators (86) are mounted on each access door and arranged to radiate through a microwave chamber and microwave-transparent window on the access door into the vacuum chamber. The waveguides on a respective access door are oriented to minimize microwave interference between the magnetrons on that door. A conveyor (60) in the vacuum chamber moves the organic material (96) on trays (18) through the vacuum chamber.
