The articulated transfer platform include a distal platform segment and a plurality of intermediate platform segments. A distal locking mechanism is releasably securable to a locking mechanism of a lead intermediate platform segment, and locking mechanisms of successive intermediate platform segment are releasably securable to locking mechanisms of preceding intermediate platform segment. In a stowed position, the successive intermediate platform segments are positioned below the lead intermediate platform segment. In an extended position, the distal platform segment is located laterally away from the device body, the distal locking mechanism is secured to the locking mechanism of the lead intermediate platform segment, and the locking mechanism of a successive intermediate platform segment is secured to the locking mechanism of the lead intermediate platform segment.Type: ApplicationFiled: January 12, 2022Publication date: February 29, 2024Inventors: Ngoc Phuong BUI, Philip CHANG, Trevor Jordan VAUGHAN, Alexandre LEMAY, Veronica GUTHRIE, Jayiesh SINGH

Patent number: 11891341Abstract: This disclosure provides resin formulations which may be used for 3D printing and thermally treating to produce a ceramic material. The disclosure provides direct, free-form 3D printing of a preceramic polymer, followed by converting the preceramic polymer to a 3D-printed ceramic composite with potentially complex 3D shapes. A wide variety of chemical compositions is disclosed, and several experimental examples are included to demonstrate reduction to practice. For example, preceramic resin formulations may contain a carbosilane in which there is at least one functional group selected from vinyl, allyl, ethynyl, unsubstituted or substituted alkyl, ester group, amine, hydroxyl, vinyl ether, vinyl ester, glycidyl, glycidyl ether, vinyl glycidyl ether, vinyl amide, vinyl triazine, vinyl isocyanurate, acrylate, methacrylate, alkacrylate, alkyl alkacrylate, phenyl, halide, thiol, cyano, cyanate, or thiocyanate.Type: GrantFiled: May 30, 2020Date of Patent: February 6, 2024Assignee: HRL Laboratories, LLCInventors: Zak C.

Publication number: 20230416160Abstract: Some variations provide a pre-ceramic matrix composite comprising: a precursor pre-ceramic matrix; reinforcing elements disposed within the precursor pre-ceramic matrix; and a compressible material disposed on the surface of the reinforcing elements and interposed between the reinforcing elements and the precursor pre-ceramic matrix. Other variations provide a ceramic matrix composite comprising: a ceramic matrix; reinforcing elements disposed within the ceramic matrix; and a compressed material disposed on the surface of the reinforcing elements and interposed between the reinforcing elements and the matrix. The coating of compressible material prevents cracking during processing because the coating absorbs stresses associated with volumetric shrinkage of the ceramic matrix during densification, thereby reducing the stresses at the interface between the reinforcing elements and the ceramic matrix. Methods of fabricating ceramic matrix composites using the principles of the invention are disclosed.Type: ApplicationFiled: September 7, 2023Publication date: December 28, 2023Inventors: Mark O'MASTA, Phuong BUI, Tobias SCHAEDLER
