Patent SE-7710894-L (SE)
Inventor: SUMITOMO H
IPC: F28B1/02
Filed: 1977-09-29
Abstract: A plate type condenser comprising a plurality of heat transmitting plates which are assembled in side-by-side contacted relation and enclosed in a container or shell, with a gasket disposed between adjacent heat transmitting plates in such a manner that suitably opened steam passages and closed cooling liquid passages are alternately defined in the internal clearances of the plate assembly. The plate type condenser is constructed to improve the heat transmitting performance in that the pressure loss of steam at the steam inlet opening in the side-by-side contacted plates is reduced and the gaskets for preventing leakage of cooling liquid are fixed; that short pass between the plates and the shell is prevented to limit the flow of steam to a given direction; and that the influences of uncondensable gases contained in the steam on the heat transmitting performance of the condenser are minimized with due consideration given thereto.

Abstract: A prefabricated expansion joint element for forming a surface joint between two concrete construction parts (1,2). The joint element has a central, resilient member (4) and anchoring members (5,6) connected to each side thereof. According to the invention the anchoring members are formed by profile elements (5,6) of epoxy plastic with at least one reinforcing layer (7) castthereinto, said layer also extending through the intermediate resilient member. The external surface of the central resilient member (4) is connected to and aligned with the external surface of the profile elements (5,6). The profile elements (5,6) are securably by adhesion directly onto the edge portions of the conceret construction parts (1,2) so as to provide easy mounting, long life and resistance to severe climatic conditions and heavy loads.

Abstract: A fluid purification system for performing filtration of particles from a feed liquid by a tangential flow of the feed liquid over a membrane surface. In one embodiment, the purification system includes a filter cartridge contained within a filter housing having ports permitting ingress and egress of feed liquid and filtrate. The cartridge includes a filter element having a layered construction with a thin flow channel between the layers. One layer of the filter element is formed of a sheet of impervious material defining one wall of the thin flow channel. Another layer of the filter element is spaced from the one layer and formed of a sheet of permeable membrane material and defines another wall of the thin flow channel. The spacing between the walls of the thin flow channel is maintained by a sheet of reticular material that provides turbulence in the thin flow channel to promote cross flow filtration. The filter element is formed into a pleated, cylindrical shape with a flow axis parallel to the pleats.

Abstract: A switching circuit (2) consisting of CTD lines (p1,q1,p2,q2,p3,q3) is specified in which the properties characteristic for non-unidirectional microwave lines (FIG. 1) are also retained for CTD switching circuits (FIG. 2). To that end, CTD lines (for example, p1,q1) exhibiting mutually opposing conducting directions are combined into a line pair and each incoming line (p1) is connected with each out-going line (q1). The connection ensues partially via CTD lines (c1+c1') and, for the other part, via a galvanic line (L1). Such switching circuits can be employed for the construction of CTD filters with steepness-increased transmission characteristic and also for the construction of correcting circuits.

IPC: G01R23/02
Filed: 1979-09-10
Abstract: A programmable number of pulses N, of one or more auxiliary frequencies fa, is inserted between pulses of the frequency f1 to be processed. The resulting frequency N.f1, where N is a positive number (N can be fractional), is at any moment proportional to input frequency f1 where N, the proportionality factor, varies at will and can assume any positive number value. Pulse insertion results in a frequency shift of positive or negative value and succeeds continuously and without any information loss i.e. the pulse train has not to be interrupted and is processed "on (the) line". The same method described used for higher frequencies eliminates the known +/-1 count problem as it can register fractions of a pulse.

Abstract: An improved fluid transfer system for a tanker vessel adapted for the transportation of fluid chemical and petroleum products in water. The vessel includes a hull comprising a bottom and sides, a top deck, a plurality of watertight cargo compartments disposed within the hull between the top deck and the hull bottom for receiving the fluid products, cargo expansion trunks coupled to and opening downwardly into each of the cargo compartments, branch vent lines coupled to the cargo expansion trunks and including pressure/vacuum relief valves, and a longitudinally disposed trunk vent line including a pressure/vacuum relief valve coupled to the branch vent lines and communicative with the atmosphere for venting contaminated gases formed by the fluid products and contained within the cargo compartments of the vessel from the cargo compartments through the cargo expansion trunks and the branch vent lines to the atmosphere. The improvement of the invention comprises bypass vent lines including vent closure valves which are coupled at one end to the trunk vent line of the vessel and at the other end to the cargo expansion trunk of at least one cargo compartment of the vessel. The vent closure valves are adapted to be opened and couple the trunk vent line to the cargo expansion trunk of the cargo compartment through the bypass vent line and thereby bypass the pressure/vacuum relief valve of the branch vent line to vent contaminated gases from the cargo compartment through the cargo expansion trunk and the bypass vent line to the trunk vent line of the vessel.

Abstract: A load control system for a boiling water reactor power plant. A recirculating pump speed demand signal and a total steam flow demand signal are derived on the basis of combination of a first control signalproduced in accordance with a power difference signal representative of difference between an actual value of an output power of an electric generator and a set value for the generator output and a second control signal produced in accordance with a pressure difference signal representative of difference between an actually measured value of the reactor pressure and a set value therefor. Speed of a recirculating pump is controlled in dependence on the recirculating pump speed demand signal, while opening degrees of a governor valve and a bypass valve of a turbine are controlled in accordance with the total steam flow demand signal. The recirculating pump speed demand signal and the total steam flow demand signal are derived by combining the first or the second control signal which has been regulated through gain elements. Further, the power difference signal is added to the pressure difference signal for modifying the set point for the reactor pressure.

Abstract: The present invention relates to a support 1 for a wall opening, made from metal sheet and placed above an opening 2 located in brick masonry 3. In order to avoid the necessity of combining the wall-opening support 1 with reinforcing bars in the horizontal joints between the masonry layers of the finished wall located above the opening 2, the support 1 is made from non-oxidisable acid-resistant metal sheet and its two ends 8 are folded up. Each of the edges of the ends is placed in the joint between two bricks 7, 3 of the first layer laid above the opening and this space is filled with mortar. The two ends of the support 1 are thus anchored into the masonry; the support 1, the bricks and the mortar joints act in a combined fashion and as a result the support 1 of the opening 2 of the wall serves not only as a masonry template which remains in place, as a water-draining means and as a covering for the lower face of the masonry, but also as a structural element in the masonry beam located above the opening 2 of the wall, absorbing stresses. <IMAGE>
