Patent SE-0300561-L (SE)
Inventor: NORDENSTAM CLAES
IPC: C05F17/907
Filed: 2003-03-03
Abstract: Cooperating lateral cavities and locking tabs are distributed around the circumference of opposing flanges (10-15) of adjoining pairs of ring sections (2-5). The result is a bayonette joint (9) between the two ring sections which also prevents the latter from rotating relative to each other.  A compost vessel (6) comprises a number of ring-shaped vessel sections made from plastic, a ventilated base plate (7) and a lid (8). The opposing flanges of the adjoining pairs of ring sections have lateral cavities and locking tabs distributed around their circumference. The width of these cavities varies and they combine with the tabs to form a bayonette joint between the adjacent ring sections, as well as creating a rotation-preventing snap-fit lock to keep at least one tab in a locking position. The joint is formed by inserting the tabs into cavities and twisting the ring sections relative to each other.

Abstract: The burner comprises a pipe with a straight part extending through the furnace wall and a curved part located inside the furnace, as well as a valve body located inside the curved part of the pipe and movable in an axial direction relative to the burner nozzle. The valve body is actuated by a mechanism which is controlled by a device located partly outside the furnace and which is connected to a control motor that receives a signal from a flow meter, which in turn is connected to a control means on the data screen monitored by the furnace operator. A motor parameter can be altered by the operator in order to adjust the control mechanism, which in turn alters the flow of air through the nozzle.

Patent SE-7710520-L (SE)
Inventor: ANDERSEN H S
IPC: F15B13/01
Filed: 1977-09-20
Abstract: The invention relates to a hydraulic motor assembly which includes a hydraulic servomotor operable in either direction with a control valve. When the motor is operated in a selected direction, as distinguished from the return direction, it is desired that external forces acting on linkage connected to the piston of the hydraulic motor do not alter the speed of the piston. The control valve has two operating positions and two sets of supply and return passages which facilitate operation of the servomotor in either direction. A brake valve between one of the servomotor ports and the control valve has a scanning port which scans or senses the downstream pressure of either of the control valve supply passages, depending on the control position of the control valve. When the servomotor is operated in the selected direction and an external force as referred to above is encountered, the brake valve operates in response to an increased pressure in the return line and a decreased pressure in the supply line, sensed through the scanning port thereof, to throttle the flow of return fluid in the return line to thereby dampen the tendency of the servomotor to accelerate responsive to the externally applied force. In addition to this function the brake valve is also arranged to allow the return line to be pressurized with supply fluid to effect movement of the servomotor in the return direction.

Abstract: The pintle shaft of a radial piston hydraulic pump-motor is cantilevered from one end frame member by guideways which permit it to be moved laterally for adjustment of the speed, torque output and direction of rotation. A reaction assembly is journaled in a second frame member by means of the input-output shaft. The reaction assembly includes two reaction rings, one on either side of the cylinder block, which rotate on bearing blocks on the pintle shaft, the bearing blocks and shaft having interengaging parallel, flat slide surfaces which permit the shaft to be translated while still being in mutually supported and stabilized relation with the reaction rings. The side loads on the pintle shaft are counteracted by friction forces developed between the slide surfaces on the bearing blocks and pintle shaft so that the pintle shaft remains stable relative to the reaction assembly without direct mechanical support of its blind end against side loads.

Abstract: A ventilator for use on a conduit having an upwardly open mouth has a generally toroidal annular flow body surrounding the conduit immediately below the mouth thereof. This body has an outer wall having an outwardly convex lower portion spaced outwardly from the conduit and an upper portion extending generally asymptotically upward and inwardly from the lower portion to the conduit and joining the conduit substantially at the mouth. Air flow is induced over the body to create a low-pressure zone at the mouth by providing a horizontal deflector disk suspended above the mouth and having an outer periphery extending outwardly beyond the mouth so as to define with this mouth an annular gap having a flow cross section greater than that of the mouth. The disk may be combined with a fan that generates a downwardly flaring air stream that moves downwardly around the periphery of the disk and across the gap.
