Title: Improvements in method of and means for cleaning the water tubes of heat exchangers
IPC: F28G9/00
Filed: 1956-05-15
Abstract: 792,214. Cleaning heat-exchangers. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. May 15, 1956 [Jan. 13, 1956], No. 15152/56. Class 99(2). In a method of cleaning the tubes 12 of a heat-exchanger 11 by the use of compressed air or other gaseous medium, a large amount of bubbles of the medium is admitted to the liquid to be passed from the end chambers of the exchanger to the tubes, those bubbles being carried by the liquid into the tubes and producing a turbulent movement therein. As shown, the tubes 12 of a condenser are divided into a number of sections 18 by inclined plates 19 along the upper surfaces of which extend apertured pipes 20 connected to a manifold 21, the flow of air through each pipe being controlled by a valve 22.

Title: Shutting down high-temperature reactors
IPC: G21C7/00
Filed: 1973-03-29
Abstract: 1435602 Controlling nuclear reactors HOCHTEMPERATUR - KERNKRAFTWERK GmbH 29 March 1973 [13 April 1972] 15189/73 Heading G6C Shut down of an HRT (which may be a pebble bed reactor) is initiated by interrupting or reducing the removal of power from the core to achieve an increase in temperature coupled with a decrease of reactivity resulting from the negative temperature coefficient of reactivity of the core. Subsequently, heat may be removed in measured amounts. The interruption may be achieved by switching off the gas circulators. The increased temperature level can be maintained over a long period by means of decay heat production. The measured removal of heat can be achieved by the reduced use of the gas circulators or by separate means. Alternatively, the removal of heat can be intermittent. For long term shut down, control rods can be inserted in the reflector after power removal has been interrupted or reduced, and the rate of heat removal increased. Subsequently, with the core operating at a lower temperature, shut down rods can be inserted. In a modification, prior to the interruption or removal of power, control rods are inserted in the reflector to lower the temperature associated with criticality. These rods are, in themselves, incapable of withdrawing sufficient reactivity to render the core sub-critical. By the method of the invention, the shut down rods are protected from damage which might otherwise result from their use in the high temperature environment.

Filed: 1946-05-20
Abstract: 612,231. Enclosing paper in boxes. LUNDBERG, J. O. May 20, 1946, No. 15234. [Classes 18 and 94 (i)] A container which when packed with stacked sheets of paper is of rhombic cross-section comprises a front 2, rear wall 5, top 6, and bottom 10 and has open sides. As the sheets are withdrawn through an opening 3 the container collapses thus holding the sheets together. Stop bands I prevent the sheets falling out of the open sides. The ends of the bands are folded round the edges of the opening 3 and of slots in the rear wall. As the container collapses the bands slide down the slots and down the V-shape opening 3. The corners of the bands may be rounded to facilitate the sliding movement. Alternatively the edges of the container may be cut and clipped together. The rear wall and top may have extensions 7, 8, which are clipped together and by which the container may be suspended. The corners of the container may be rounded as indicated by the dotted lines. In an alternative construction the last sheet of paper may project through a slot in the rear wall to assist in holding the pile in position.

Title: Manufacture of biologically active fission products of the adrenocorticotropic hormone
IPC: A61K38/35
Filed: 1951-06-29
Abstract: Biologically active fission products of the adrenocorticotropic hormone are obtained by hydrolysing the hormone and simultaneously dialysing the reaction solution, the fission products being isolated from the dialysate.  The hydrolysis vessel is preferably a tube of flexible semipermeable material e.g. "Cellophane" (Registered Trade Mark) closed at one end, capable of being rotated, and arranged within a somewhat larger glass tube which is immersed in a water bath at a predetermined temperature.  The external liquid used for dialysis has approximately the same pH as the internal liquid, and the external liquid is continuously renewed.  Preferred hydrolytic agents are proteolytic agents such as pepsin or trypsin, but other agents such as dilute hydrochloric acid may be used.  In examples (a) the adrenocorticotropic hormone from pig pituitaries is hydrolysed with 0.05 N hydrochloric acid containing pepsin at 37 DEG  C. and the external liquid is 0.05 N hydrochloric acid continuously stirred. Every 30 minutes the external liquid is replaced by fresh liquid previously heated to 37 DEG  C.  The active material is obtained by freeze drying the dialysate; (b) Crude extract from whale pituitaries is hydrolised in 0.05 N hydrochloric acid containing pepsin and saturated with toluene.  The external liquid 0.05 N hydrochloric acid is continuously renewed.  The process is interrupted after three hours for a further addition of pepsin; (c) a crude extract from sheep pituitaries is treated as in (b).

The wall is in two parts consisting of two high sides 12a and two low sides 12b and is yieldingly supported at the corners by springs 16 which rest in brackets 14 depending from the platform 10. Handles 17 serve for the lowering of the walls and handles 11, acting also as legs for the platform, are used for moving the apparatus against the room wall &c. For holding the apparatus in a steady position against the wall, guiding means is provided consisting of a pair of rails 19 surrounding two sides of the platform and adjustably supported by brackets 20 secured to the brackets 14. The rails are secured in the heads 25 of screws 23 which work in the brackets 20. Additional guiding means in the form of a screw 20 is mounted adjacent a corner of the platform. Plaster is applied to the platform in the horizontal position and the apparatus is then lifted to the wall or ceiling and the. walls 12 lowered. Excess plaster flows from the platform through cut-away parts 31 of the walls into a surrounding trough 32. To prevent the plaster from sticking to the platform, a strip 34 of waterproof material may be placed on the platform, being removed from the wall or ceiling after the plaster has set. In the case of the first coat of plaster, the platform may have a number of spring fingers adapted to project from the surface of the plaster in order to hold the latter in place.
