Abstract: Aspects described herein may relate to a transaction exchange platform using a streaming data platform (SDP) and microservices to process transactions in accordance with corresponding workflows. The transaction exchange platform may generate configuration transaction objects to reconfigure microservices with salt values and time periods of salt value validity. Further, the microservices may retrieve transaction objects from a streaming data platform and generate hash signatures as part of determining the validity of the transaction objects. Furthermore, in some aspects the microservices may retrieve salt values for transaction objects that cannot be verified due to the absence of a hash signature. The salt values may be retrieved from a blockchain associated with the streaming data platform and may be used to update the microservice to include the salt value.

One aspect includes a method of offset load testing comprising: providing a testing apparatus having a pair of arms including a fixed arm and a mobile arm; providing a tubular composite specimen with a top portion and a bottom portion; securing the pair of arms to the top and bottom portions of the tubular composite specimen; and moving the mobile arm to impart an offset load force to the tubular composite specimen.

Abstract: In an aspect, there is a method of determining allowable defects for a composite component comprising identifying at least one wrinkle characteristic of a composite component wrinkle defect; making a first plurality of specimens each having a predetermined wrinkle defect representative of the composite component wrinkle defect; measuring each of the predetermined wrinkle defects in the first plurality of specimens for at least one performance metric to generate performance data; and generating an allowable wrinkle defect profile based on the performance data from the first plurality of specimens. In other aspects, there are methods of making a specimen with a predetermined wrinkle defect.

Abstract: A frozen battered fish product, method and apparatus for production. The product comprises a fried batter coating with a pre-defined pattern of ridges and troughs which create a textured batter surface. A frozen aqueous protective layer is disposed over a part of the batter coating to protect textured features including the pattern of ridges and troughs. The aqueous protective layer is designed particularly to provide protection when a more brittle frying batter is used, as a result of using a frying medium with lower saturated fat content.

Abstract: A tiltrotor aircraft includes a fuselage, a wing member extending from the fuselage, an engine disposed relative to the wing member and a proprotor mechanically coupled to the engine. The proprotor includes a plurality of proprotor blade assemblies each including a spar and a sheath extending spanwise along the spar forming the leading edge of the proprotor blade assembly. The spar has a root section, a main section and a tip section. The spar has a generally oval cross section at radial stations along the main section and a first edge having a structural bias relative to a generally oppositely disposed second edge at the radial stations along the main section.

The central portion includes a central radial bearing configured such that the central portion twists in response to cocking of the first bearing housing relative to the second bearing housing.

Abstract: According to one embodiment, a drive link includes a first bearing housing, a second bearing housing, and a central portion coupled between the first bearing housing and the second bearing housing. The central portion has less torsional stiffness than the first and second bearing housings such that the central portion twists in response to cocking of the first bearing housing relative to the second bearing housing.

Abstract: A portable wash device includes an elongated shaft having a water inlet unit on one end and one or more rotating brush pads on the other end. The brush pads are rotated by a motor under instruction from a control handle. The device also includes a detergent reservoir for combining cleaning solution with water for projection by a nozzle, and an adjustable spray device for allowing a user to manually direct water to an object. A spray shield is located near to the brushes to prevent water and debris from impacting a user while operating the device.

Abstract: A steel for use as a broachable workpiece having a substantially pearlite-free microstructure whereby the service life of the broach tool is maximized. Formation of pearlite is suppressed by alloy modification; on-line processing; off-line processing; or combinations of these techniques which control the microstructure and hardness levels. The workpiece is broached into the form of a powertrain component such as, for example, a gear or race which can be surface hardened after broaching by one of carburizing, nitriding, or induction hardening depending upon the carbon content of the steel. Disclosed are steel compositions and processing methods for making the steel, the broachable workpiece and the broached and surface hardened powertrain article.
