Patent number: 10119585Abstract: In some examples, an article may include a carbon-carbon composite, an antioxidant in pores in a surface of the carbon-carbon composite, and a hydrophobic coating on the surface. The hydrophobic coating includes an oxide of a metal. The metal has a Pauling electronegativity of less than about 1.7. In some examples, the article may be a carbon-carbon composite brake disk that includes a carbon-carbon composite substrate defining a friction surface and a non-friction surface. The antioxidant may be a phosphate-based antioxidant, and the antioxidant may be in pores in the non-friction surface. In some examples, the hydrophobic coating is on the non-friction surface over the phosphate-based antioxidant. In some examples, the hydrophobic coating may include a majority of at least one of yttrium oxide, scandium oxide, or zirconium oxide.Type: GrantFiled: January 7, 2016Date of Patent: November 6, 2018Assignee: Honeywell International Inc.Inventors: Richard George Rateick, Jr., Stephen Frederic Yates

Patent number: 10119586Abstract: A brake element is sensorized by at least one piezoceramic sensor arranged between a metallic support element and a block of friction material of a brake element, the sensor being completely embedded within the block. An electrical voltage signal generated by at least one piezoceramic sensor, without the need for a power supply, is picked up by an electrical circuit integrated into the metallic support element. The electrical voltage signal is processed in the form of equal length of samples per unit of time of the detected signal by successively processing in real time each sample of equal length of time sample of the signal by applying an algorithm. The algorithm is selected from at least one of a sequence of integrations of voltage values in the sample carried out in an interval of time in the order of milliseconds; FFT voltage data sample; and integral of the voltage data sample.Type: GrantFiled: April 16, 2014Date of Patent: November 6, 2018Assignee: ITT ITALIA S.r.l.Inventors: Fabrizio Merlo, Luca Martinotto, Daniele Donzelli, Mattia Solari

Patent number: 10119587Abstract: A shock absorbing device that has high strength rigidity and good attenuation characteristics, that can be reduced in weight and size, is free from degassing, and has stable temperature characteristics. The device connects between a first and second member so as to be applicable to shock absorption therebetween, and includes: a first and a second shock absorbing member; and a holding and connecting mechanism which holds the first member via the first and second shock absorbing members and which is connected to the second member. The first shock absorbing member, the first member, and the second shock absorbing member are disposed in that order. The holding and connecting mechanism sandwiches the first shock absorbing member, the first member, and the second shock absorbing member from outside the first and second shock absorbing members, thereby holding the first member while applying stress to the first and second shock absorbing members.Type: GrantFiled: January 23, 2017Date of Patent: November 6, 2018Assignee: WEL RESEARCH CO., LTD.Inventor: Kazuki Watanabe

Patent number: 10119588Abstract: [Object] Damage to a surface of a resin bush caused by press-fitting is prevented even when a configuration for positioning during welding is added. [Solving Means] A rolled collar (40) is a steel rolled collar into which a resin bush (90) is pressed-fitted, and which is joined to a joining member by welding. The rolled collar includes a main body part (50) formed in a hollow cylindrical shape, and a clinch part that joins both end surfaces of the main body part together by fitting. The rolled collar includes a notch part (70) formed by cutting off a portion of an annular edge (53) in the main body part. Here, a convex jig determining a position of the main body part at a time of welding is fit into the notch part. The rolled collar includes a cavity part (80) formed to be hollow from an inner circumferential surface side on a wall surface around the notch part to form a clearance (81) between the press-fitted resin bush and an edge portion (71) of the notch part on the inner circumferential surface side.Type: GrantFiled: March 25, 2014Date of Patent: November 6, 2018Assignee: Yorozu CorporationInventors: Yutaka Kuroi, Shingo Yokoyama
