Patent SE-7704864-L (SE)
IPC: B04B5/04
Filed: 1977-04-27
Abstract: A centrifuge rotor having a sealing element which automatically controls in response to the centrifugation operation the fluid communication between separate fluid mixture chambers within the rotor. The sealing element is situated within the rotor above an annular and an inner chamber used for containing a fluid mixture. When the rotor is assembled and stationary, the sealing element establishes a seal between the respective chambers. During the rotation of the rotor in a centrifuge, the centrifugally induced pressure exerted by the fluid mixture moves the sealing element, releasing the seal between the respective chambers and allowing fluid communication between the chambers. As the rotor returns to a stationary position and the centrifugally induced pressure of the fluid mixture subsides, the sealing element automatically re-establishes the seal between the respective chambers.

Abstract: In a heat resistant cabinet, a gypsum filling is provided in the interspace between the outer casing and the inner surface. In the upper part of the cabinet, at least one hollow space is present in the gypsum filling. This hollow space extends practically over the whole width and the whole depth of the cabinet. The ceiling is therefore provided by two relatively thin plates of gypsum spaced from each other and each containing a wire mesh for reinforcement, providing a good heat protection for the contents of the uppermost drawer, without adding any substantial vulnerability to impairment of heat protection by falling material or by falling of the cabinet.

Abstract: The primary coil (14) of a coil arrangement (14, 16) is fed by a frequency generator (12) having selectable frequencies. The secondary coil (16) is connected to a phase detector (18) which detects phase changes occurring in the signal of the secondary coil (16) when a conductive object (20) is brought into the magnetic field of the primary coil (14). The pure resistance component (R) of the impedance change occurring by bringing the object (20) into the previously calibrated coil arrangement, divided by the frequency (F) supplied changes as a function of frequency and discloses a single peak value at a single characteristic frequency value. These values are compared with characteristic data of known objects, for example stored in a computer. Both values depend on the type and the geometry of the conductive object. For an object made of metal, the characteristic frequency is proportional to the specific resistance of the object divided by its cross-sectional area. Using the device according to the invention, it is possible to obtain accurate information on the type of a conductive object, for example a hidden handgun at the airport. It is also possible to identify various metallic components, if present, in an object. Conductive solutions, animal tissues and others can also be identified. <IMAGE>

Abstract: Apparatus for transferring toner magnetically adhering to magnetic images stored in a magnet image-storage medium to a toner-adherable receiving medium such as paper. Included is a platen which presses the paper against the storage medium to form regions of contact and noncontact between the paper and storage medium. A boundary between the two regions is defined by a line of contact. The apparatus also includes magnets for producing a magnetic field in the paper and storage medium which is asymetrical with respect to the line of contact. The field is stronger in the region of noncontact than in the region of contact. In the preferred embodiment, the field originates from a pair of spaced-apart, confronting magnetic poles disposed on a side of the paper opposite from the storage medium. The apparatus is structured to produce selectively a field in the storage medium having a magnetizing force less than or, alternatively, greater than, the coercivity of the storage medium.

Abstract: Valve means for an anaesthetic system which comprises an inhalation means, such as an anaesthetic mask, a gas supply system for the supply of a mixture of gases containing oxygen and an anaesthetic gas, at least one valve (64, 65) for regulating the gas flow in the system and an outlet (67) or the like for the controlled discharge of used gas. The valve means incorporates a sensing means (53, 56) so arranged as to sense the gas speed and the direction of the gas flow in a gas duct inside the system, and a power means (61) so arranged as to cause the valve to open when the speed of the gas in a pre-determined direction exceeds a certain value. The sensing means incorporates a duct (53) with a constriction (56) and on either side of the construction inlets to two lateral ducts (57, 58). The power means (61) is so arranged as to cause the valve (64, 65) to move to its different positions by utilizing the higher pressure which arises because of the direction of flow of the gas and its rate of flow on the arrival side of the constriction in relation to the lower pressure downstream of the constriction. It takes the form of two chambers (59, 60) which are connected to the lateral ducts (57, 58) and which are separated by a movable organ such as a membrane (63) to which the valve is connected. The difference in pressure which occurs in the sensing means as the gas is flowing thus provides control of the valve.

Abstract: The folded bag side edge areas (21,23) become side wall parts of the bag as it is filled. This means that the base width of the bag is reduced from its normal manufactured dimension (B) to a lower (B2) one. - In order to fill bags with material with differing densities, where the bags have the same length and breadth dimensions, the bags are made with a normal base width. Where the inserted material has a larger density, a bottom width reduction is necessary, so that the requisite volume reduction in the filled bag is achieved. Filling in this case can take place using the largest dimension for the filler pipe employed, i.e. corresp. to the largest bag base width.
