Patent ES-8102632-A1 (ES)
Title: Turbine control system for sliding or constant pressure boilers
IPC: F01K7/24
Filed: 1980-05-28
Abstract: An automatic control system enabling comprehensive operation of a reheat steam turbine with sliding or constant pressure boilers. The control system includes an HP control valve for regulating steam flow to the high-pressure turbine according to load and speed demands, an intercept valve for regulating steam flow to the low-pressure turbine and for reheater pressure control, and a bypass flow system for bypassing excess boiler steam during periods of low loading. The bypass system includes a high-pressure bypass sub-system and a low-pressure bypass sub-system, each having a flow control valve and provision for desuperheating the steam. A signal indicative of actual load demand (ALD) and proportional to the product of boiler pressure and main control valve flow demand is produced. From the ALD signal, reference functions are generated to effect control of the bypass valves. The intercept valve is controlled directly by the ALD signal with a regulation factor inversely proportional to the minimum allowable reheat pressure. Coordinated valve control is effected during all principal phases of turbine operation.
Patent ES-8107384-A1 (ES)
Title: Recuperators for heating air by furnace gases
IPC: F24H3/06
Filed: 1980-11-28
Abstract: Heat from hot furnace gases passing through a flue 21 is recuperated to heat air by passing the gases through a high temperature exchanger 1a from top to bottom and then through a lower temperature exchanger 2a from bottom to top, the exchangers being positioned with their longitudinal axes extending vertically and being laterally spaced from each other (e.g. side-by-side) the air (e.g. combustion air) passing first through the heat exchanger 2a in the opposite general direction to that of the gases, and then through the heat exchanger 1a in the same general direction as the gases. Deposits from the hot gas which form on the heat exchange surfaces and subsequently become detached therefrom, collect in a chamber 20 of the flue and are removed at 22.

Patent ES-8204620-A1 (ES)
Title: Self-pressurizing dispensing container.
IPC: B05B9/04
Filed: 1980-12-18
Abstract: A flexible enclosed plastic bag disposable in a product container for supplying dispensing pressure therein. The bag cofltains an envelope having its outer sides permanently attached to the respective inside walls of the bag. One of the sides of the envelope has one of a two component gas generating system disposed in a plurality of aligned pocket members formed therein with their openings facing the other side of the envelope, the latter being releasably adhered to the first mentioned side to enclose said one component in said pockets. The bag contains the second component and a starting means to initially generate gas and expand the bag and develop product dispensing pressure within the container. As the product is dispensed, expansion of the bag causes sequential separation of the sides of the envelope and serial opening of the pockets to add aliquots of the first component to the second component and further generate gas and maintain said pressure in the container until substantially all of the product is dispensed from the container.

The laminate forming structures is preferably tubular in shape so as to facilitate continuous plastic web processing against its outermost surface. Film to be debossed and selectively apertured is brought in contacting relation with the laminate structure and subjected to a fluid pressure differential on said forming structure while at a temperature above its softening temperature. The fluid pressure causes the heated plastic film to be debossed in those areas where said initially perforate selectively apertured lamina contacts the film and debossed and apertured in those areas where said initially perforate selecticely apertured lamina does not contact the film. The debossed and selectively apertured film is thereafter cooled below its softening temperature before removal from the forming structure.

Patent ES-8504366-A1 (ES)
Title: Shaft seals.
IPC: F16J15/46
Filed: 1984-05-17
Abstract: A shaft seal comprises a housing (22) containing a sealing ring (20,720) consisting of a sleeve (24,724) of plastics such as PTFE and an elastomeric ring (30,730) surrounding the sleeve. The dimensions of the sleeve (22,722) are such that fluid can leak between the sleeve and the shaft (10). Fluid pressure is applied to the elastomeric ring (24,724) to apply radial force to the sleeve (22,722) to reduce the leakage of fluid to an acceptable level while maintaining a hydrodynamically stable fluid film between the sleeve and the shaft. The energizing fluid pressure may be supplied from a separate source, or be derived from the system fluid pressure, for example by allowing the fluid to flow through ports (780) in the elastomeric ring (730) to the annular space (748) between the elastomeric ring and the housing. The fluid film between the sealing ring and the shaft reduces wear on the ring and shaft and reduces the heat generated by friction between the ring and the shaft.

Filed: 1985-06-14
Abstract: The invention relates to an optical transmission system for two-way transmission of subscriber-specific messages between a central office and a number of subscribers, particularly the subscriber line area of a wide-band communication system. The optical waveguides (5a to 5n) of a group of spatially adjacent subscribers (3a to 3n) are coupled in a front-end device (2) via wavelength-division multiplexers-demultiplexers to a common optical waveguide (4), which is connected to the central office (1) and each subscriber is individually allotted his own wavelength or his own range of wavelengths. Preferably, in the central office and in the front-end device bidirectional optical wavelength-division multiplexers- demultiplexers (11, 21) are used and the subscriber's lines to these multiplexers and the optical waveguide (4) between the central office and the front-end device are used for transmitting in both directions. As a result of the wavelength-division multiplex operation on the optical waveguide (4) which is to connect the central office to the front-end device and the purely passive optical selective front-end device, the costs of the system can be kept low, system reliability increased and flexibility and expandability ensured. In two exemplary embodiments (Figure 2, Figure 3), the front-end device consists of locally distributed subscriber-specific units (21a to 21n, 22a to 22n).
