An air-induction system of an engine includes a hose assembly. The hose assembly includes an elastomeric hose having a circular cross section when in a natural state, and a deformable sleeve received around the hose and configured to create an indentation in the hose for part clearance. The sleeve has an end section having a circular cross section and an intermediate section in which the sleeve projects radially inward into a sidewall of the hose such that the hose is deformed from the natural state to a deformed state in which the sidewall is deformed radially inward creating the indention and a non-circular cross section of the hose at the intermediate section.

A method for insulating a gas-fueled water heater includes providing a tank for storage of water for heating and a combustion chamber adjacent to the tank. The method includes providing a compressed foam barrier circumferentially around the tank. Further, the method includes positioning a covering around the tank from a top end to a bottom end, the covering extending over the compressed foam barrier. Moreover, the method includes decompressing the compressed foam barrier such that an outer diameter of the foam barrier expands up to and seals against the covering so as to separate an internal volume defined between an outer surface of the tank and the covering into a first section and a second section. Then, the method includes injecting a foam material into the first section so as to provide a foam barrier around at least a portion of an outer surface of the tank.

The present invention relates to a water-soluble pre-reacted binder composition, a method of its manufacture, a use of said pre-reacted binder composition, a method of manufacturing a collection of matter bound by a polymeric binder, a binder solution or dispersion comprising said pre-reacted binder composition, as well as products comprising the pre-reacted binder composition in a cured state.

A thermal insulation device includes a first plate, a second plate formed to nest adjacent the first plate with a gap between the first and second plates, a porous material disposed between the plates, and a sealing layer disposed between the first and second plates such that the porous material is sealed from ambient at a pressure less than ambient. Multiple such sets of plates may be used to form an enclosure for a device that thermally insulates the device from ambient.

Provided are a preparation method of a silica aerogel-containing blanket which includes mixing a water glass solution, a polar organic solvent, and a silazane-based surface modifier to prepare a sol, preparing a silica gel-base material composite by immersion and gelation of a base material for a blanket in the sol, and drying the silica gel-base material composite, and a silica aerogel-containing blanket prepared by using the preparation method.

A silica aerogel-containing blanket having a high degree of hydrophobicity as well as excellent physical properties, particularly, low tap density, high porosity, and excellent mechanical flexibility may be prepared by the minimal use of a surface modifier without a surface modification step by the above method.

The reinforced removable thermal insulation (PARTS) contains the heat-insulating blocks joined among themselves placed on an external surface of the heat-isolated equipment. The Asti block is filled with heat-insulating material and consists of a reinforcing frame lattice sheathed on all sides with facing stainless sheets. For mutual detachable connection of heat-insulating blocks between themselves the lock latch is used. When using the proposed lock-latch, a guaranteed tightness is provided, the disclosure of thermal gaps between the side faces of thermal insulation blocks from the inaccessible internal bases of thermal insulation at temperature fluctuations is excluded, fitting works and welding of tension locks on the surface of their blocks in place during installation and Assembly work on the equipment are excluded. Asti blocks are able to save the weight of stainless steel, increase the strength of thermal insulation blocks by 2.56 times, significantly reduce the cost of their manufacture.

A pipe coupling for coupling a first pipe to a second pipe wherein a gap exists between a first pipe end and a second pipe end. The pipe coupling includes a tubular insert configured to fit within the gap and match an inside diameter and outside diameter of the pipes, thereby providing a through-butt joint between the insert and the pipes. The pipe coupling also includes a half-tubular first fitting section and a half-tubular second fitting section, configured to snap-lock and form a tubular shape over the insert, the first pipe end and the second pipe end. In some embodiments, the insert is integral with the fitting sections.

A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support that maintains a vacuum space between a first plate and a second plate. The support includes a first support plate provided by coupling at least two partial plates to support one of the first plate or the second plate, and a second support plate that supports the other one of the first plate or the second plate.
