摘要:
The present invention relates to a device for providing heat radiation of a surface which is intended to be radiated for softening and removing of old paint, putty or furnish or drying of moisture. The heat radiation from the device is obtained by means of electric resistance wires forming a heat radiation element arranged in an open box. In particular, the invention relates to an arrangement for making the device more resistant to shocks which is achieved by attaching the heat radiation element resiliently relatively to the casing. The invention further relates to a reflector unit for such a paint removal device for reflecting of heat radiation comprising a reflecting surface, at least one heat radiating element and resilient suspension attachments, said reflector unit comprising a plurality of attachment points for mounting of the resilient suspensions attachments thereto, the at least one heat radiating element being attached to at least two resilient suspension attachments so as to face the reflecting surface of the reflector unit.

摘要:
A device for removing layers of paint from a surface including layers of paint which may comprise a base layer of oil paint. The paint is softened by radiation by means of at least one heating source. Immediately thereafter, the paint is removed mechanically from the surface. The apparatus comprises a carrier which may retain one or more sources of infrared radiation, a device for guided travel of the carrier in the horizontal plane along the painted surface and a device for guided travel of the carrier in the vertical plane along the painted surface.
摘要:
A suspension device for a paint, varnish or putty removal devices, is intended to be arranged near or in contact with a wall, a ceiling, a floor or the like, and adapted for treatment of old paint, putty or varnish on the surface of an object by means of heat radiation. The suspension device includes a horizontally pivotable arm which at one end portion is displaceably mounted and horizontally pivotally arranged on a bar. The other end portion of the arm supports one or several paint removal devices which are rotably connected to the arm. The arm includes at least a first and a second rigid section being horizontally pivotally connected to each other round a vertical axis.

The valve is designed to be connected to a sanitary waste pipe system for admitting atomospheric air into the waste pipe towards the valve function elements in response to a pressure reduction in the system in order to protect the water traps in the system and to prevent discharge of contaminated air from the system to the atmosphere. It includes an oblong bowl-shaped valve housing (10), a vertical tubular member (12) extending downwards from the housing (10) and adapted to be connected to the waste pipe system, an inner space (18) within the valve housing (10) and containing the valve function elements (34), at least one passage (26) from the valve function elements (22) towards the surrounding atmosphere and a cover member (14) overlying the inner space and having a top wall spaced above the valve function elements (20, 22, 34). The valve housing (10) is provided with at least two valve function elements (20, 22, 34) each having a circular valve seat (20) extending downwards in order to create a tubular space (22) within and connected to the valve housing (10), and a movable valve member (34) having a bowl shaped central portion (36) and a peripheral conical edge (38) extending upwardly, the outer surface of which is resting on the circular valve seat (20) in closed condition.

摘要:
The invention relates to a valve for admitting atmospheric air into the waste pipe system in response to pressure reduction in the system for protecting the water traps in the system and to prevent atmospheric discharge of contaminated air from the waste pipe system. The valve consists of a valve body having at least two air inlet openings in communication with the atmospheric air, each of the openings alternating with a passage towards the waste pipe system, the openings and passages being equally distributed within the valve housing viewed in horizontal cross-section about the valve seat level. The valve member resting, in a normal closed position, on the valve seat separating the openings from the passages and having a substantially butterfly shaped sealing surface for a valve embodiment having two diametrically opposed openings situated perpendicular respectively to two diametrically opposed passages.
