Title: Piping support of gas turbine steam cooled combustor
Inventor: TAKAHASHI SYUICHI
IPC: F16L3/08
Filed: 2000-07-21
Abstract: Piping support of gas turbine steam cooled combustor is improved such that, even when the piping support is damaged by combustion vibration, piping is prevented from dropping so as to avoid the occurrence of fractions thereof from entering into the turbine portion. An outer fitting member (11) is fixed to the wall surface of a tail tube (102) by welding (82, 83). A ring (12) is pinched inside the outer fitting member (11) to be fixed by welding (80). The ring (12), having an inner diameter slightly larger than the outer diameter of the steam piping (101), is fitted in around the steam piping (101) to be fixed by welding (81) at three places. The steam piping (101) is fixed to the ring (12), the ring (12) is fixed to the outer fitting member (11), and the outer fitting member (11) is fixed to the tail tube (102), such that the steam piping (101) is supported to the tail tube (102). Thus, even when the welding (82, 83) is detached by combustion vibration, the outer fitting member (11) remains fixed to the steam piping (101).

Inventor: DUNCAN DAVID
IPC: A47J45/10
Filed: 2000-11-10
Abstract: A kitchen grip or implement for kitchen use is composed of a water-resistant and stain proof material having temperature control characteristics. Such a material forms the implement from at least one sheet having a textured, recessed or irregular surface providing a non-slip contact surface while the opposite surface of the sheet is composed of a close fabricated fabric which is affixed to the sheet of non-slip contact surface material. The fabric sheet may be a sheet of nylon/polyester composition which is affixed to the non-slip contact surface sheet which may be composed of a chloride rubber. The sheets are die cut to the shape of a useful implement such as a hand mitt, a trivet, a lid holder or the like. A two-piece implement such as a hand mitt requires that two sheets of the fabric and chloride rubber composition be sewn together by means of a zigzag lock stitch employing nylon thread.

Inventor: SHEPPARD JAMES M JR
IPC: D06Q1/00
Filed: 2001-01-11
Abstract: The present invention relates to both a textile article and a method of making the textile article. The textile article is a two-sided Jacquard woven textile with a graphic impression on at least one side thereof. In one embodiment, the front side of the textile has a dark color border and a light color area within said border. The light color area is the area receiving the graphic impression. It is sometimes advantageous to reverse the textile. Therefore, in another embodiment the front side has a light color border with a dark central area, and the dark central area will receive the graphic impression. The graphic impression may be applied by screen printing, image dyeing, digital imaging, or heat transfer (heat applied graphics). The method of making the article comprises the steps of providing a two-sided Jacquard woven textile and then transferring the impression onto the textile, preferably in the light color central area, but the reverse side of the textile could be employed and the impression could be on the dark central area. The textile may be a golf or sports towel, hand, bath, or wash towel, beach towel, baby bib, a bath or beach robe, a bath mat, an apron, hot-plate, mittens, and the like.
