Abstract: A device for simple setting up of stationary central vacuum cleaning installations in dwellings or the like. The device is in the form of a housing (6) with the purpose of accommodating a conventional vacuum cleaner (7) of the type that comprises an intake air inlet (22) to which a long suction hose (8) is connectable. Parts of the housing are detachable from the rest of the housing in order to enable adjustment of the vacuum cleaner in the interior of the housing. In the housing, an aperture (25) is formed for leading through the hose (8) to the vacuum cleaner, as well as an outlet.

Abstract: A password setting system for a secure system includes a user token server and a communication module. The user token server generates a random token in response to a request for a new password from a user. The server creates a new password by concatenating a secret passcode that is known to the user with the token. The server sets the password associated with the user's user ID to be the new password. The communication module transmits the token to a personal communication device, such as a mobile phone or a pager carried by the user. The user concatenates the secret passcode with the received token in order to form a valid password, which the user submits to gain access to the secure system. Accordingly, access to the system is based upon: nonsecret information known to the user, such as the user ID; secret information known to the user, such as the passcode; and information provided to the user through an object possessed by the user, such as the token.

Abstract: A sewing machine including a needle being supplied with an upper thread, a loop taker which accommodates a bobbin for a bottom thread. and a drive unit, which forces the needle to perform a reciprocating movement. The needle, during its movement and in cooperation with the loop taker, executes a stitch on a sewing material being advanced between the upper thread and the bottom thread. A take-up lever, for each stitch, pulls tight a knot being formed in the sewing material by the upper thread and the bottom thread in cooperation. The sewing machine further includes a thread transfer member supplying the needle with an upper thread with either a thread portioner or a friction braking assembly for friction braking of the upper thread. A switch switches between thread supply with the thread portioner or with the friction braking assembly. A control unit controls the thread supply from the thread portioner or, alternatively, controls the friction braking assembly.

Abstract: The present invention relates to a plate heat exchanger with a number of heat transfer plate (1) arranged between two end plates (3,4). Two guiding bars, which extend from one end plate (3) to the other end plate, are formed in one piece of one and the same rod (5).

Abstract: A valve arrangement for a pressure fluid, particularly high-pressure oil, has a valve housing (10, 90, 190) with an internal, cylindrical sealing surface (16, 100, 160) which forms a guide for the outer, cylindrical sealing surface (42, 107, 162) of a piston body (18, 106, 138). There is provided a circular groove which accommodates a sealing ring (46, 64, 108, 164). An axially displaceable valve sleeve (30, 70, 122, 156) is disposed coaxially with the two cylindrical sealing surfaces(16, 42, 100, 107, 162, 160) and has a cylindrical valve-sealing surface (40, 74, 124, 158). This valve sleeve is biased by a spring (34, 80, 118, 172) such that one end (36, 82, 126, 174) abuts substantially sealingly a seating (38, 86, 128, 176) at that end of the sealing surface such as to form a closed gap (41, 86, 130, 178) at one end of a channel (32, 73, 132, 145).

Abstract: This invention relates to a lining for lining inlet ports and outlet ports in a frame plate or a pressure plate for plate heat exchangers and comprising a cylindrical portion and two flanges which are connected to the cylindrical portion and which during the use of the lining are positioned on each side of the frame plate or pressure plate. According to the invention the lining comprises a rigid part having a cylindrical portion (6; 9; 13B; 16) and a flange (3; 8; 13A; 19) being an integral part of the cylindrical portion, and that the remaining part of the lining is made of an elastic material.

Abstract: The present invention relates to a plate heat exchanger comprising heat exchange plates clamped between a frame plate and a pressure plate, the frame plate and the pressure plate having ports with linings for intake and outflow of media to be heat exchanged and the heat exchange plates having ports in alignment with corresponding ports in the frame plate and the pressure plate round which ports of the heat exchange plates ring gasket grooves extend. According to the invention the one of the frame plate or the pressure plate (1) facing the rear side of the ring gasket groove (4) of the heat exchange plates is provided with linings (2; 14; 22; 23) which do not require machining of the plate (1) at the area of the ports and that the sealing between the lining (2; 14; 22; 23) and a heat exchange plate (3) is brought about by means of a ring gasket (10; 21) engaging the ring gasket groove of the heat exchange plate (3) positioned closest to the frame plate or the pressure plate (1).

Abstract: In a plate heat exchanger having a frame plate and a pressure plate, at least one of these plates has holes for flow of the heat exchanging media to and from respective passages in the pack of heat exchange plates. Each of these holes has a lining of corrosion-resistant metal comprising a hollow cylinder with thin flanges at its opposite ends engaging opposite sides of the frame plate or pressure plate. One of these flanges has a seamless connection with the hollow cylinder and is sealingly compressed between a heat exchange plate and an undepressed surface of the inner side of the adjacent frame plate or pressure plate. Lining of the hole is effected by plastically deforming a metal disc into a hollow cylinder with a flange at one end, inserting the other end of the cylinder through the hole to engage the flange with said undepressed surface, and then providing said other end of the cylinder with a flange engaging an undepressed surface of the outer side of the frame or pressure plate.
