Abstract: A heat exchanger element comprises two metal layers 10, 11 abutting each other and a pipe 15 of metal arranged therebetween for a heat-carrying medium. The pipe extends between two opposite outer edges of the element. The metal layers 10, 11 are cold welded to each other on both sides of the pipe 15, and the pipe 15 is cold welded to the metal layers. The pipe 15 is further provided with two protruding flanges 16, 17, which are arranged on each respective side of the pipe and extend in between the metal layers 10, 11, whereby also the protruding pipe flanges are cold welded to the metal layers. The heat exchanger element is manufactured by two abutting metal strips 10, 11 and a metal pipe blank 12, 13 situated therebetween are fed in between rollers for obtaining such a pressure that the metal strips are cold welded to each other and to the metal pipe blank. The metal pipe blank consists of two metal strips 12, 13 abutting each other, whereby a central section of one strip is prepared to prevent cold welding to the other strip, such that the strips may later be separated along this section for the formation of a pipe for the heat- carrying medium. The heat exchanger element is in particular intended for solar collector devices in order to enable improved heat transfer between the heat-collecting surfaces and the heat-carrying medium. <IMAGE>

Abstract: Dilution of liquid samples is effected by drawing one sample at a time through an aspirating tube (12) dipped into the sample and through a volumetrically calibrated measuring passageway (17) in a movable valve body (16) of a metering valve (11), whereupon the valve body (16) is moved and the sample volume trapped in the measuring passageway (17) is expelled into a mixing vessel (23) together with a predetermined, many times larger volume of liquid diluent such that the diluent rinses the measuring passageway. Further rinsing of the valve body (16) is then effected with wash liquid. Wash liquid is also passed to a rinsing vessel (32) in which the end portion of the aspirating tube (12) previously dipped into the sample is inserted so that this end portion is rinsed exteriorly with the wash liquid. In a final step, wash liquid in the rinsing vessel (32) is drawn through the aspirating tube (12) to rinse it interiorly, whereupon air is drawn until the aspirating tube and the measuring passageway (17) are emptied of liquid.

Abstract: An arrangement on a maximum-temperature regulator for combination heating boilers, which regulator is provided in order to interact with the operating-temperature regulator of the boiler and is designed such that, in the event of an excessive temperature of the boiler resulting from a defect in the operating-temperature regulator, the electrical supply network which is connected to the boiler is disconnected. The maximum-temperature regulator comprises a voltage-sensing device (11) which is suitable for defining a signal corresponding to the operating state of the boiler, and an excessive-temperature device (15) which is suitable for defining a signal corresponding to the boiler water temperature. Furthermore, the maximum-temperature regulator is designed such that, with the aid of a switching device (13, 16), the electrical supply network which is connected to the boiler is disconnected if a signal corresponding to the excessive temperature in the boiler is sensed at the same time as a further signal which corresponds to electrical or heating-oil operation of the boiler. <IMAGE>

Abstract: Novel hydrogel compositions, comprised of a blend of two thermoplastic uncrosslinked polymers, one of which is hydrophobic, and the other hydrophilic, and having a microphase separated morphology are described. These hydrogel compositions are useful as devices for controlling the release rate of bioactive agents, such as therapeutic drugs, antimicrobials, contraceptive agents, or the like, in a biological environment. Depending upon the chemical nature of the agent to be released, its rate of release can be controlled by appropriate selection of the polymeric components of the blend and their relative ratios.

Abstract: The algorithm used to calculate the access code or key word can be simple, e.g. a doubling of the ranoom number, or more complicated, e.g. even numbers are increased by 3, odd numbers are reduced by 1 and halved. The method can be further developed by joining the algorithm to other data, e.g. data or day of the week. This can be achieved e.g. by shifting the algorithm on different days, or by allowing the date to be used as a factor in the algorithm. - If the terminal incorporates a striking clock which is synchronized with the computer clock, the clock strike can also be joined to the access code, e.g. the code can be terminated by the second number, or an algorithm of it, An example is as follows: The access code is to be 1000 - 2 x random number and terminated by the indicated minute number followed by the second number x 2 Radom number is 153 The access code remains 694 The clock indicates 14 39 x 42 The code is terminated by 3984.

Abstract: This invention concerns a floor drain in which a floor covering 6 is secured to the inner surface of the side wall 2 of the drain by means of a locking ring 7 which presses the floor covering 6 against the side wall. To secure the locking ring in place, the side wall 2 of the drain is shaped such that the floor covering forms an inwardly directed bead 9 above the locking ring 7. Obtaining a locking ring which can be driven past the bead 9 and which despite this presses the floor covering 6 against the side wall 2 of the drain under the bead has been a problem. According to the invention, the problem has been solved by placing a sealing ring 10 in the inner surface of the side wall 2, which sealing ring comprises bead-forming lips 11 which are inflexible. <IMAGE>

Abstract: The invention relates to the manufacture of plastic boats in a sandwich construction using so-called square-cut cellular-plastic material as spacing material. For the purpose of ensuring that the gaps of the cellular-plastic material (6) are completely filled, a curable filler substance (4) is applied to the inner surface of the outer laminate (3) and a spacer member (mesh 8) and a sealing layer (plastics 9) are placed over the cellular-plastic material (6). A suction element (10, 11) connected to a vacuum source of about 0.9 atmospheres is then activated, such that the filler substance is positively drawn up into the gaps (5) in the cellular-plastic material (6). This takes place so quickly that it is possible to apply filler immediately and to apply the inner laminate (7) wet-in-wet.

Abstract: The present invention relates to a process for correcting misalignment of steel bands circulating about a continuously operating press and to a press adapted for such correction of misalignment. The press has a fixed press bed and a movable press top and a pair of endless flexible steel bands circulating around the press bed and the press top and defining a press gap between them having a high pressure zone, a medium pressure zone and a low pressure zone. The press top is flexible, at least in the high pressure zone, the flexing being controlled by piston and cylinder assemblies arranged on opposite longitudinal sides of the press. The bands pass over driven and deflection rollers on opposite sides of the press gap and at least one of the rollers is adjustable so that its axis of rotation can be moved. When realignment of one of the steel bands is required, the short stroke piston and cylinder assemblies are operated on one side of the press to reduce pressure on the band at that side, and then the axis of rotation of the adjustable roller is moved to cause the desired realignment. In this way, stretching and deformation of the band during realignment can be avoided.
