摘要:
The arrangement is intended for flashing of a roof penetrating building construction and comprises a rail member (4) adapted to be connected with a member (1) of a frame construction for the building structure to extend, when mounted, substantially along the entire length thereof, and a deformable skirt member (9) which at an edge portion (7) thereof positioned, when mounted, at a distance from the frame member (1) is connected with an edge portion of the rail member (4) and adapted to be brought into abutment with the surrounding roofing. The arrangement comprises a supporting means (10) to be positioned between the frame member (1) and the joining (6, 7) between the skirt member (8) and the rail member (4).

The roof flashing material is intended for use in connection with skylight windows and the like roof penetrating structures and comprises a sandwich construction with two outer layers (2, 3) of metal foil and at least one intermediate layer (4; 5-7) positioned between the outer layers, said material having at least in one direction a continuous waveform. The intermediate layer(s) (4; 5, 6) adjacent to the outer layers is/are made from a non-adhesive resilient material, and said waveform is formed in such a manner that it maintains the mutual positioning between the outer layers and the adjacent intermediate layer(s) by friction.

A drive unit for electrically operated doors, windows, screening devices and the like, comprises a drive unit casing (5) containing a motion transfer member (4) in engagement with a reversible drive motor (1) with an associated motor control circuit. The drive unit is designed as a program-controlled unit with a microprocessor (6) with an associated reprogrammable memory (7) which contains operating parameters for the drive motor (1) and can be programmed and reprogrammed from the outside via the current supply conductors (8, 9) to the drive unit by means of an external programming device (16) via an interface unit (17) which by connection to the current supply conductors (8, 9) brings these into a programming condition deviating from a normal operating condition and in which data can be exchanged between the microprocessor (6) and the external programming unit (16).
摘要:
The present invention relates to a well head system, especially in connection with high pressure wells, and in order to reduce the weight of steel involved, as well as avoiding unnecessary equipement in the well head, it is according to the present invention suggested a casing programme based on liners, having the same pressure integrity as the casing on which the well head is mounted.

The roller shutter (4) for screening the light-admitting area of a window sash (2) comprises a length of slats (5) which at their interspaces (6) are mutually articulated by means of hinge joints, a spring-loaded roller (10) rotationally embedded in a case (8) at the top member of the sash for rolling up the slats (5), a guide rail (7) mounted at each side member (2b) of the sash running in the direction of the roof inclination for guiding the ends of the slats (5) during rolling up and down of the slat length, and a drive mechanism (11) comprising a drive shaft (13) mounted parallel to the roller and a driving device (14) arranged at each guide rail (7) and having carriers (15) for driving engagement with the slat length. The carriers (15) of the driving device (14) engage the slat length at the interspaces (6) between the slats (5).

The windbox burner has a register casing (2) with ports (3) for inflow of combustion air, a secondary air pipe (35) enclosed by the register casing and having inlet ports (36) for secondary air, a ring damper (20) coaxial with the register casing and axially displaceable and having at each end an annular sealing means (21; 26) which in the closed position of the ring damper sealingly abuts a corresponding sealing means (23; 22) at each axial end of the ports (3), thus preventing the combustion air from flowing through the ports (3) to the burner tip. Each of the sealing means (21, 23; 22, 26) is made of a stainless and heat-resistant material, and each pair of sealing means is constituted by a plane leaf spring (23; 26) the plane of which is substantially perpendicular to the longitudinal axis of the ring damper (20), and a ring (21; 22) with a convex surface on which the leaf spring abuts tangentially in the closed position of the ring damper.
摘要:
A feeder unit comprises a storage hopper, a weighing cell, a conveyer, and a discharge end. The storage hopper is to be connected to a refilling system and the discharge end to a receiving container. A working space is defined by the arithmetic product of the dead weight of the feeder unit and the refilling interval, such that the working space is below 0.2 kgh. Furthermore a method for discharging a constant mass flow of one or more powders into a receiving container is defined.
摘要:
The sash (2) of the window is connected with the frame (1) by means of a hinge device including a set of pivot hinges (12) defining a hinge axis of the window. The hinges are mounted in such a position that the hinge axis is situated between a centre line of the window and the top or bottom of the window. The window is provided with a least one auxiliary opening device comprising at least one pressure medium operated cylinder (124) with an operating rod (123). At least one hinge comprises check means restricting the movement of the window.
