Patent SE-8005148-L (SE)
Inventor: BOMAN L E
Filed: 1980-07-14
Abstract: The present invention relates to an absorbing product such as e.g. a napkin, a sanitary towel or similar, comprising an absorption body and a shroud 8, 9 surrounding it. What characterizes the invention is that the absorption body consists of at least three superimposed sheets 1, 2, 3, of which the inner sheet 1 situated nearest to the user during the use of the product is in general uncompressed, the intermediate sheet 2 situated adjacent to said inner sheet is strongly compressed, preferably in liquid dispersing areas 4 extending in the longitudinal direction of the product, with areas 5 situated between said liquid dispersing areas and essentially compressed relative to the inner sheet but considerably less compressed than the strongly compressed areas 4 in the intermediate sheet 2, and the outer sheet 3 is in its entirety compressed considerably stronger than the areas 5 in the intermediate sheet 2 situated between the dispersing areas 4. Hereby, it is obtained that the absorption body is being filled with absorbed liquid from the outer sheet 3 situated farthest away from the body of the user, in the direction towards the inner sheet 1 situated nearest to the body of the user. <IMAGE>

Abstract: In this method of cleaning exhaust gases by removing the sulphur dioxide, the hot gas is brought into contact with an absorption liquid in a drying apparatus, where evaporation of any water carried in and reaction between the sulphur dioxide and the absorption material take place, after which the solids are removed in a dust separator. In order to bring about a higher reaction speed in the dust separator, a substance is added to the exhaust gas which forms a liquid phase distributed over the surface of the solids. The liquid phase normally contains water and has good solubility for reactants and products of reaction.

Abstract: A filter assembly is disclosed for use, in-line, in a medical fluid, e.g., parenteral solution, administration set or the like, to filter the fluid as it is administered to a patient. Hydrophobic and hydrophilic filter membranes are mounted in a parallel-flow relationship within a filter housing, which is sealed except for inlet and outlet ports. The membranes are respectively positioned so that the hydrophobic filter membrane is located above the hydrophilic filter membrane when the filter assembly is suspended in-line in an administration set, permitting any air separated from the fluid by the hydrophilic membrane to migrate upwardly and pass through the hydrophobic membrane instead of accumulating on the surface of and blocking flow through the hydrophilic membrane.

Title: Electronic lock system with memory and comparison circuit - has electromagnet activated on coincidence of stored data with key code to withdraw lock bolt stop
Inventor: RUUS J
IPC: E05B47/00
Filed: 1982-02-24
Abstract: An encodable key comprises a grip part and a section which can be encoded. This section comprises a number of limited fields with specific dimensions which are simply altered by being removed or blocked, thus, imparting a unique code format to the key. The lock system used with the key has a keyhole into which the key is inserted, a lock bolt and a stop. The keyhole contains a current source activator whose action is brought into play or cancelled by the key being inserted or withdrawn from the hole. When activated, the current source feeds probes which monitor the key code content. A memory and comparisons circuit when there is concidence between the key code contents and that of the circuit, feeds current to an electromagnet. This magnet withdraws a stop, freeing the lock bolt. (Provisional Basic advised week 84/32).

Abstract: A sharpening strip (1) for a cylinder lawn mower is fitted with a groove shaped recess (7) designed to be pushed over the mower's lower blade (6) so that the strip is thereby retained by it.  The strip includes a stiff section which carries a sharpening device (5). This device (5) is designed to face in the direction of the mower's blade cylinder (8), so that the cylinder's blades can be sharpened by the cylinder's rotation, when the cylinder and the lower blade are adjusted relative to each other so that the cylinder blades move across the sharpening surface on the sharpening device.  This sharpening device is made up of a thin strip (5) of a grinding material on one side, forming the sharpening surface.  The stiff section is arranged so as to leave at least the side of the lower blade (6), which faces the blade cylinder (8), mainly free, but to grip the lower blade from its opposite side with a gripping part (4). The section has in its fitted position, a surface situated outside the lower blade, which is placed facing the blade cylinder, whereby the sharpening device is fixed to the said surface outside the lower blade by an edge section, while the rest of the strip's sharpening device projects outside the said surface in a situation opposite to the section bar's gripping part (4). Thereby the groove shaped recess (7), whish is designed to enclose the lower blade (6), is contained between the section's said gripping part (4) and the part of the sharpening device (6) which sticks out over the fixed surface. The sharpening surface is thereby situated at a short distance, corresponding to the sharpening device's thickness, from the lower blade's edge, at the same time as the sharpening device flexibly adjusts itself to the edge's length and thereby offers the cylinder blades (8) an appropriate shape corresponding to this length during sharpening.<IMAGE>

Abstract: Teat cups are linked to a receptacle which feeds via a choke into the vessel coupled to a vacuum. The teat cup vacuum can be raised during milking above a first level or lowered below a second level by a control block with mode indicator. Between the receptacle (7) and choke (8) the milk line (6) contains a hydropneumatic transducer (15) linked to a membrane comparator (32-35) control block (12) to convert milk line pressure to a pneumatic signal output. The output is fed to the block input (16). A first output signal (13) is formed when the pneumatic signal reaches a first preset level due to milk production rising to the first preset level, and a second control signal for reduction in pneumatic signal due to production falling below the second level. In series with the transducer and parallel to the choke linking the transducer to the vessel (9), when production falls below the first level, is a slave valve (17) to link the transducer to the vessel, when production rises above the first level.

Abstract: Non-returnable packages for liquid contents, e.g. milk, are made frequently from a flexible packing laminate, and are provided with an opening arrangement in the form of a tear-off strip which covers a pouring opening in the packing container wall. So as to avoid spatter and spillage at the actual moment of opening an opening arrangement for packing containers is realized comprising a pouring opening (8) which has a projection (8') of small area directed against the direction of tearing of the tearing strip (6). This part of the pouring opening (8) formed as a projection (8') thus will be opened first, and airwill flow into the packing container, and the liquid level will drop so that the continued opening can be performed without any risk of spillage. By varying the sealing strength between the tearing strip and the packing laminate an automatic delay of the removal of the tearing strip after the opening of the projecting part can be achieved, which further improves the functioning of the opening arrangement.

Abstract: A thin flexible lightweight electrical heat wrap unit usable on the human body, usually with a vibratory massaging device. In the heat wrap unit, electrical resistance wires are arranged in a serpentine pattern and sealed together with a thermostat between two thin flexible composite sheets. The composite sheets comprise a knapped loop fabric material inseparably laminated to a base of electrically insulating pliable material. The base faces of the sheets are bonded together thereby causing the fabric loops to be on all exterior sides of the heat wrap. The heat wrap unit operates on 12-24 volts and has an enclosed socket electrically connected to the resistance wires and structurally attached to an edge of the wrap unit. The socket is connected through an external temperature control unit and transformer to a power supply. Also, a vibrator massage device can be electrically connected to the control unit and physically attached by a Velcro (R.T.M.) fastener to the heat wrap unit outer surface and used in combination with the flexible heat wrap unit to achieve combined effective heating and massage capability for the user.
