Patent SE-8102638-L (SE)
Inventor: KREIJ S-E
IPC: F16K1/226
Filed: 1981-04-27
Abstract: A sealing device for valves comprises two co-acting sealing surfaces one of which is arranged facing outwards on a valve body which is pivotally mounted in the valve housing, and the other forming an inwards-facing surface on the seat arranged in the valve housing. When the valve is closed the two sealing surfaces are pressed against each other with a wedge-wise engagement along an engagement line or engagement zone. According to the invention at least one of the sealing surfaces is formed as a segment (S) of a toroidal figure (T) which is defined by a convex or concave curved line (G) which is rotated as a generatrix around an axis of rotation (R), out of which figure the segment is cut so that a plane (A) through the sealing surface, along which the engagement line or engagement zone is located when the valve is closed, is inclined relative to the axis of rotation (R) and is bounded in each and every direction from the latter by the curved line.

Abstract: Armoured mats for cross-country vehicles comprised of two link systems (6 and 7) with transverse straps (8) or cross-irons arranged in-between. Each transverse strap (8) is fastened onto its own link by its ends. The number of links is reduced due to the ends (12) of the transverse straps (8) being shaped so that each and every one functions as a link. The invention forms a stable armoured mat which is easy to assemble by opening the links (14) which unite the transverse straps (8) that after assemblage are closed through the splicing element (18) which is firmly welded (19 and 20) to the links (14).<IMAGE>

Abstract: A loudspeaker is provided for high-quality and particularly stereophonic sound reproducing systems positioned close to a wall of a room. To reduce distortion due to that part of the reflected sound which arrives from substantially the same direction as the direct sound, the positioning of the sound radiating surfaces is such as to make the reflected sound from the wall arrive substantially in phase with the direct sound throughout a large frequency range, while at higher frequencies the reflected sound is attenuated by a sound absorber. The loudspeaker has a casing with a rear wall (5a). Loudspeaker units arranged to be the sound source for mid-range (12b) and/or high (14a) frequencies has the sound radiating surfaces (12b, 15a) at short distance (D2, D1) from the plane of the rear wall (5a) and facing slantwise forwards. A sound absorber (28a) at the side of the casing, in front of and near the plane of the rear wall (5a) and near the sound radiating surfaces (12b, 15a), serves to attenuate that part of the sound reflected by the room-wall which has wave-lengths shorter than eight times the shortest distance (D1, D2) of the sound radiating surfaces from the plane of the rear wall (5a). In stereophonic systems the left-hand and the right-hand loudspeakers form a mirror-image pair.

Abstract: A compression device particularly for aluminum cans comprises a frame and an endless driven belt mounted therein and provided with friction means on its outer side. A hold-down member in the form of a plate of a low-friction elastic plastic material is so disposed along and opposite one run of the belt that this run and the hold-down member at one end (inlet end) of the belt will be spaced from each other a distance which exceeds the maximum diameter of the can to be subjected to compression, and progressively approach one another such that they will be located close to each other at the opposite end (discharge end) of the belt. The hold-down member is fixedly anchored to the frame at the inlet end of the belt and bears on rubber springs at the discharge end of the belt, whereby a can received at the inlet end of the belt is progressively compressible in an advantageous way, such that a completely flattened can body will leave at the discharge end of the belt, with one can end pressed against one flat side of the can and the other can end pressed against the opposite flat side of the can.

Title: Double diffraction grid monochromator for emission spectroscopy - has scanning device with two electric motors each connected to diffraction grid
Inventor: AKERLUND STIG ALLAN
IPC: B60P7/06
Filed: 1982-05-25
Abstract: The double grid monochromator has an input slot, a first diffraction grid an intermediary slot, a second diffraction grid and an output slot. These elements are optically connected to each other and arranged in the direction of propagation of light. A scanning device modifies the angular positions of the diffraction grids in the course of exploration of the emission spectrum. The scanning device has a first electric motor kinematically connected to one of the diffraction grids and a second electric motor kinematically connected to the other diffraction grid. It also has two transmitters for the angular positions of the grids. A programmer generates signals determining the angular positions of the diffraction grids during exploration of the emission spectrum giving a relation between the angles of incidence of light on the two diffraction grids. Two comparators form signals corresponding to the difference between signals applied to their two inputs. One input of each comparator is connected to one of the outputs of the programmer and the second input to the output of the transmitter of the angular position of the corresponding diffraction grid. Two mixers each have an input connected to the output of one of the comparators and an output connected to the input of the corresponding electric motor.

Abstract: Dialyzers and methods are disclosed for performing shortened extracorporeal blood treatments. A flow restriction is provided in a dialyzer serving to partially impede flow of dialysate through the dialysate compartment of the dialyzer. As a result, the pressure of the dialysate upstream of the flow restriction is sufficient to cause the pressure profile of the dialysate from the dialysate inlet to the dialysate outlet of the dialyzer to be non-linear, in contrast to prior-art dialyzers. This perturbation of the dialysate pressure profile permits a single dialyzer to be used to remove large amounts of blood water from a patient's blood and re-infuse large amounts of liquid to the blood while still attaining a desired net ultrafiltration of the patient without the need for more than one dialyzer per treatment or for a separate replacement fluid.
