  • Publication number: 20240314910
    Abstract: The invention relates to a field of electric equipment, in particular, to an electric light switch, namely, to a touch light switch to be mounted in a wall of a building. The set of essential features of the present solution enables to achieve such a technical effect as increase of convenience mainly increase of the light weight, the light switching on/off process due to provision of the large area of the touch area on the touch printed circuit board, thus, a high sensitivity on the touch display panel is achieved, i.e., along the entire front area of the device; simplification of mounting of the switch in buildings having old wiring and increase of safety of the device structure. This design of the touch light switch affects the correct operation of the device, thereby enhancing the receipt of signals and decreasing the probability of incorrect commutation of the switch and its failure during mounting.

  • Patent number: 4576226
    Abstract: The herein disclosed multipass corrosion-proof preheater comprises a plurality of passes. The passes are formed by bundles of heat-transfer tubes for the passage of heating gases and interconnected in series, with respect to air supply, by means of connecting air lines. Air is supplied to the tubefield of the heat-transfer tubes via air supply line accommodating a device designed for high-temperature preheat of part of the air supplied to the tubefield of the heat-transfer tubes of the first pass. The air preheater further comprises a bypass air line serving to communicate the air line with the connecting air line via mixer mounted in the latter. In addition, the air preheater is provided with a device for low-temperature preheat of air, mounted in the air line upstream of the device when viewed in the direction of air flow. The bypass air line is connected to the air line between the devices for low- and high temperature air preheat.

  • Patent number: 4501320
    Abstract: Air enters each pass of a two-pass air heater in the same direction with respect to gas flows. Bypass air conduits connect each tube bundle of a first tier to the tube bundle of a second tier of adjacent gas ducts and are located between inlet and outlet air conduits and have common walls therewith.The bypass air conduits connect the tube bundles of all the gas ducts in a single closed (ring) circuit. It is possible to set the gas ducts either along the radius on a single circumference or in a joined-up arrangement with the gas ducts divided into two halves by a vertical partition.In an alternative embodiment, the bypass air conduits connect the tube bundles of all the gas ducts in an open circuit, the tube bundles of both tiers of the extreme gas ducts are half as wide and are arranged to form a single pass with respect to the air flow.The thermal efficiency of the air heater is the same as that of a Z-criss-cross type air heater.

  • Patent number: 4452181
    Abstract: A device for heating air by flue gases in steam boilers and furnaces, comprises a supply flue, sections mating therewith, and a device for protection of heat-exchange tubes against abrasive wear arranged in the flue. Each section comprises heat-exchange tubes attached to tube plates. The device for protection of the heat-exchange tubes against abrasive wear incorporates at least one screen formed by corrugated sheets facing each other and mating along the lines of contact of sheet convex portions, whereby cells are made up.

  • Patent number: 4243096
    Abstract: In an air heater, mixers of hot and cold air are built into circulating air ducts between the passes of that portion of the air heater which is exposed to the danger of corrosion. Said mixers are provided in the form of tubes perforated lengthwise and located frontally in the respective pass. Headers serving the mixers are connected to cold air feeding ducts.Perforations the tubes of each mixer are provided with serve to direct jets of cold air at right angles to the flow of hot air.The tubes of the mixer are blanked off at the opposite ends of the adjacent tubes while the open ends of these tubes are connected to different cold air headers. Used as the tubes of a mixer can be a bunch of frontal tubes in the respective passes of the air heater.The air heater disclosed offers protection against corrosion by heating a mixture of cold and hot air to a minimum temperature, and said protection is achieved in a compact light-weight apparatus requiring minimum labor for its fabrication.
