Patent ES-371099-A1 (ES)
Title: Variable length,diverse format digital information transfer system
IPC: H04Q9/14
Filed: 1969-09-01
Abstract: A system for transmitting digital data from a number of remote stations to a central station includes, in the central station, a device for sequentially interrogating the remote stations and in the remote stations a control device which, on receipt of a command signal from the central station, scans the digital data, transmits it to the central station and generates a signal signifying the end of the transmission which, when received at the central station, causes the next remote station in the sequence to be interrogated. In an embodiment the data in each remote station is divided into three groups which are scanned sequentially. The remote stations receive a signal from the central station which consists of a remote station address and a number of command, sync., and parity bits. The correct station responds by energizing its control device which causes the first group of data to be scanned under the control of a counter. When the first group of data has been scanned the control device emits signals consisting of a word signifying the end of the first data group transmission, the complement of the station address and a parity character. The control device then initiates the second data group scan and on completion emits a word to that effect. The final data group consists of a number of two state devices which are only scanned if any of them have undergone an unauthorized change since the last scan. The control then emits a word signifying the completion of the transmission. The central station includes a number of data display units e.g. printers or C.R.T.'s which are sequentially energized in synchronism with the remote station scan. The data is handled in the central and remote stations in parallel form and is transmitted in serial form. A three position switch is provided at the central station to modify the command emitted to allow the first data group only or the first and second groups only or all three to be scanned. All transmission include sync. and parity bits to enable the central and remote stations to remain in synchronism and to detect faults.

Title: Method of controlling the feed of forced circulation steam generators
IPC: F22D5/26
Filed: 1972-09-19
Abstract: The rate of feedwater flow is controlled in a first load range by the level of water in the separator while in a higher load range the rate is controlled by the steam temperature.

The strands are severed in the region between the tapes, and a plurality of guide members of plastics material are formed on the tape edges having the rows of fastening elements, each of the guide members being connected to a respective one of the severed portions of alternate ones of the strands to extend away from the respectively adjacent one of the other strands. The tapes can then be severed between the strands of each pair so as to provide completed stringer pairs with ends sealed by the welded strands. One stringer of each such pair of stringers can be fitted with a slider and - on its guide member - with an open end box member receiving the guide member of the other stringer of the respective pair. The strand portions at the ends of the stringers remote from the guide members can be suitably adapted to limit travel of the slider along the stringers.

Title: Steam trap
IPC: F16T1/10
Filed: 1976-04-09
Abstract: A steam trap allowing the escape of condensate from a working fluid of steam comprises an escape valve mounted in a chamber in which the working fluid flows. The escape valve includes a valve seat member and a deformable metal diaphragm normally closing the steam trap and preventing the escape of steam. The diaphragm closes a housing in which a control fluid of water initially only partially fills the housing to which a vacuum is later applied. The housing bears along the periphery of the diaphragm where the diaphragm is supported by a shoulder in the valve seat member. The valve seat member includes a cylindrical central chamber radially inwardly of the valve seat and an annular chamber radially outwardly of the valve seat. The cylindrical chamber is larger in diameter than and upstream of an escape passageway for carrying away condensate also in the valve seat member. The annular chamber is in communication through a check valve and passages with the chamber in which the escape valve is mounted. Accordingly the pressure of the working fluid is exerted against the corresponding outer annular portion of the diaphragm in communication with the annular chamber and preponderates over the pressure in the enclosures when there is condensate in the chamber in which the steam is mounted.
