Patent SE-8301029-L (SE)
Inventor: ROSHOFF KENNERT
IPC: G01N27/20
Filed: 1983-02-24
Abstract: The tool comprises a probe-type body of insulating material provided with a relatively thin layer of electrically conductive material so arranged that it builds a current path along the whole length of the body. This conductive material is connected to a current source and forms part of a circuit. When there is movement in the material being monitored a break in the circuit occurs, giving rise to a recordable signal. The electrically conductive material is fitted on one side of the body and in it is a track deeper than its own thickness. The track extends from the one end of the body to terminate at a slight distance from the other body end, forming a U-shaped current path. (Provisional Basic advised week 84/41)

Abstract: This relates to improvements in turbochargers and more particularly to the venting of the bearing housing of a turbocharger adjacent the compressor housing. Under certain operating conditions, insufficient air is available for the compressor intake, with the result that the compressor draws a vacuum within the compressor housing and causes an undesirable flow of lubricant from the turbocharger bearings to the compressor discharge. This vacuum is applied to the interior of the bearing housing in the general area of the oil deflector and thrust bearing. A vent passage is formed through the oil deflector and the thrust bearing and down between the thrust bearing and bearing support so as to vent that portion of the bearing housing to the lubricant drain cavity, and thereby inhibit undesirable lubricant flow to the compressor discharge.

Abstract: The invention relates to a process for the froth flotation of complex ores. In accordance with this invention, froth flotation is carried out by using a collector and froth flotation conditions for which it has been calculated in advance that the said mineral and the collector form stable surface compounds. The conditions include the electrochemical potential of the system, the concentration of the collector, the pH, and other physical factors. According to this invention it has been observed that by adjusting the potential and the concentration of the collector separately for each mineral, each mineral can be frothed out separately from the slurry, the process being in this case specific for the mineral. When so desired, the different minerals of the ore slurry can also be frothed simultaneously by selecting the conditions where the Pourfaix-type diagrams of all minerals in said complex ore overlap under the conditions in question.

Abstract: An annular wiper for piston rods, disposed in a cylindrical wall opening wherein an axially movable piston rod is running, comprises a reinforced ring of an elastic, somewhat flexible material having a portion with an inner diameter slightly greater than the outer diameter of the piston rod and an axially outwardly projecting and radially inwardly projecting lip with a somewhat smaller inner diameter than the outer diameter of the piston rod. The reinforcement comprises a first annular portion surrounding the periphery of the elastic ring, creating a torque center line for the resilient ring, and a second annular portion absorbing as a compressive force the radially inwardly directed force exerted by the elastic ring as it turns around the torque center line.

Abstract: This invention relates to an artificial menisco-tibial joint for a knee joint prosthesis of the kind which comprises at least one tibial component (1) on which the meniscus (6,6 min ) is movably disposed. The meniscus (6,6 min ) has a largely flat sliding surface against the tibial condyle which is provided with steering means (9,14) which impart to the meniscus (6,6 min ) an ability to move in all directions along the tibial condyle, the steering means (9,14) also being so disposed that they limit the magnitude of the movement. The steering means (9,14) consist preferably of two locating pins (9) situated at a distance from each other which interact each with its own running track (7) in the tibial condyle so that the meniscus (6), apart from a movement largely forwards and rearwards along the tibial condyle, is also imparted a sideways movement. Alternatively the steering means (9,14) consist of a posterior edge (14) on the metal socket (5) attached to the tibia (1).

Abstract: A ballast arrangement includes a number of tanks and a pump connected to a sea-chest and having a discharge conduit extending to a level above the top-most tank. A distribution conduit extends to the various tanks and an overflow pipe is connected to the discharge conduit and reaches to a further level, above the first mentioned level, where also an evacuation pipe is connected. The further level will determine the static pressure which may act in any of the associated tanks. The tanks may be connected to the suction side of the pump through by-pass conduits, and a two-way valve is designed so the pump can communicate only with either the sea-chest or with the by-pass conduits.

Abstract: A fire-escape made of metal consists of two side bars 1, 2 and rungs 3, 3A, 3B whose ends are hinged on the side bars with the aid of screws 51, 53, cotters or the like. At least one side bar, which constitutes the inner bar 1, is made from a U-shaped profile and is able to be secured to a wall of a building with the aid of a number of clamps 4 distributed along the bar, the said inner bar being directed with the web 11 of the U-shaped profile facing in towards the wall and with the two legs 10 facing out towards the other side bar which forms the outer bar 2. The outer bar is designed to be able to be pulled out from a retracted position, in which the inner and outer bars are against each other and the rungs are almost vertical, to a pulled-out position, in which the rungs are essentially at right angles to the side bars. Each of the legs of the inner bar is provided with at least one longitudinal flange-like elevation 12 at a distance from the web of the profile and, on the inside, with a corresponding longitudinal groove 13. The flange- like elevation on each leg constitutes an attachment for the said clamps, and the corresponding groove 13 has sufficient depth and width to be able to accommodate a screw head 50, nut or similar part of a connection member, preferably a screw 51, which extends through a hole 18 in the flange-like elevation for the purpose of fixing the clamp on the inner bar at any chosen location along the latter, so that the bars can be folded together without the rungs 3A, 3B striking an obstacle in the form of protruding screw heads, nuts or the like. <IMAGE>
