Patent ES-478921-A1 (ES)
Title: System for minimizing valve throttling losses in a steam turbine power plant.
IPC: F22B35/06
Filed: 1979-03-23
Abstract: This invention relates to a system for reducing steam throttling losses which occur across turbine governor valves, by adjusting boiler throttle pressure so as to obtain optimum govenor valve setting thereby providing for maximum power production efficiency. In a typical valve grouping sequential positioning pattern, the flow rate is assumed to be F3 where valves 1, 2 and 3 are fully open causing substantially no throttling losses however, valves 4 and 5 are partially open causing some losses. An optimum valve position program (56) is operative to determine optimum flow demands corresponding to optimum valve positions (72 and 71) which are greater and less than the present flow demand. Then, the closest optimum flow demand, e.g. (72) is selected. Based on this optimum flow demand, a throttle pressure control program (34) adjusts throttle pressure setpoint so that the governor valve (4, 5) positions change to (72). A major advantage of this invention is fuel savings due to maximum time spent in the optimum valve position conditions.

Filed: 1979-07-10
Abstract: In a plate heat exchanger in which the flow rates of the two heat exchanging fluids are different, it is possible to obtain an adjustment to differing proportions of the fluid flows, the pressure drops being given. To this end, the heat exchanger is provided with at least two sections of heat exchanging passages, in at least one of said sections the passages for the two respective fluids having essentially different flow resistances. Furthermore, the proportion of the flow resistances of the passages for the respective fluids in one section differs essentially from the corresponding proportion in at least one other section.

Title: Composite compact components fabricated with high temperature brazing filler metal, method and apparatus for making same.
IPC: B23K1/00
Filed: 1979-07-11
Abstract: A component comprised of a composite compact, preferably diamond, and a substrate bonded to the compact. A preferred embodiment of the component is a cutter for a drill bit. The compact is comprised of a layer of bonded diamond or boron nitride particles and a base layer of cemented carbide bonded, preferably under high temperatures and pressures, to the particulate layer. The particulate layer is degradable by exposure to temperatures above a predetermined temperature. The substrate is bonded to the base layer of the compact with a filler metal which, to form a bond, requires the exposure of the surfaces to be bonded to a temperature substantially greater than the degradation temperature of the particulate layer. The component is fabricated by heating the base layer, filler metal and substrate to a temperature in excess of the degradation temperature while maintaining the temperature of the particulate layer below the degradation temperature via a heat sink.

Patent ES-8200999-A1 (ES)
Title: Unit for destroying insects in closed rooms.
IPC: B05B7/24
Filed: 1980-04-02
Abstract: A unit for destroying insect pests, in particular flies, is installed permanently in a building, for example a stable, and comprises a compressed-air source (1), a filter (2), a reduction valve (3) and a solenoid valve (4), which are controlled by a chronometer (6) and a timer (5). A tube system (7) leads the compressed air to nozzle heads (8), which are mounted via a quick coupling (10) each on its individual poison container (11). Through venturi effect the flow of air through the nozzle head aspirates the poisonous liquid into said head atomizing it out in the room, where it evaporates. By distributing the containers (11) with poison evenly in the room, the danger of too strong an initial dosing resulting from remaining liquid drops from the previous spreading is eliminated, and at the same time the centrally situated compressed-air plant makes possible an extremely simple controlling of the timing of the poison distribution.
Patent ES-8106811-A1 (ES)
Title: Improved memory protection system using capability registers.
IPC: G06F21/62
Filed: 1980-09-29
Abstract: The use of protected capability registers to hold the physical base and limit addresses and access rights for a block of memory and the way in which such registers are loaded using System Capability Tables and reserved segment pointer tables is well known in the prior art. In the present invention the normal capability load instruction has been enhanced in four major ways: (a) allowing additional capability classes to be handled (b) instituting a "load on use" facility (c) instituting capability propagation control and (d) implementing access reduction facilities The capability classes comprise (i) system store, (ii) system resource, (iii) local store and (iv) passive capability. The "load on use" facility speeds up the load capability instruction and the change process instruction. The propagation control mechanism introduces an access bit which controls the storing of the capability pointer preventing the passing of the pointer from one process to another, whereas the hardware access reduction facility enables a capability to be loaded into a capability register with reduced access right.

Patent ES-8201229-A1 (ES)
Title: Tank for an electrolytic cell
IPC: C25C3/08
Filed: 1980-10-15
Abstract: During its continuous use, the carbon lining on cells used in the electrolysis of aluminum oxide frequently exhibits cracks which are formed by stresses due to the thermal dilation of the contents of the cell. The present invention prevents the formation of cracks by providing in the floor and corner regions of the tank grooves (protrusions, doming, bulging) which can be deformed elastically so as to yield to the pressure caused by the dilation until the forces on the cell walls are equalized. Also provided are horizontal, movable hollow sections, secured to the sidewalls of the metal tank. The sections bend as a result of the temperature gradient across them such that they counter the pressure on the sidewalls due to the dilation of the cell contents. This effect can be amplified by providing holes in the walls of the hollow section so as to reduce thermal conduction within the sections and thereby maintain the temperature gradient therein. The effect can be amplified by making the hollow sections out of two materials having different thermal expansion coefficients.

IPC: F15B1/08
Filed: 1982-10-08
Abstract: An inexpensive pressure vessel which can be disposed of rather than being repaired once it fails, which includes a cylindrical housing having two chambers separated by a resilient bladder. One chamber is for housing a gas while the second is for housing a fluid such as hydraulic oil. The cylindrical housing contains a port at one end and is open at the opposite end. The end cap which contains a through port and a gas valve is insertable into the open end of the cylindrical housing and is welded thereto.
