Patent ES-461948-A1 (ES)
Title: Turbocharger lubrication and exhaust system
IPC: F02B39/14
Filed: 1977-08-29
Abstract: A turbocharger system. One impeller of the turbocharger is driven by exhaust gas from an internal combustion engine, the other impeller functions as a pump to either compress air or to pump air in order to convey granular material. The impeller wheels are spaced and are mounted at the ends of a common shaft. The shaft is continuously lubricated, the spent lubricant being fed to an oil sump (crankcase). The specific improvement is a pressure bleed passageway between the chamber which receives engine exhaust pressure and the oil exhaust line. The bleed allows a portion of engine exhaust to pass to the sump exhaust line and assist oil flow to the sump by virtue of a pressure differential. This action, in turn, inhibits spent oil from passing through the seals and passing into either or both impellers when oil sump (crankcase) pressure is higher than atmospheric or where there are unfavorable to gravity flow conditions existing in the oil return line. Another portion of the system bleeds air from a high pressure reservoir to the interior of the oil sump line to assist spent oil flow to the sump.

Abstract: Apparatus for, and a process of, sector engraving metal elements, is disclosed. The apparatus includes an engraving roller having a particular pattern formed thereon, and a workpiece mounting system which is capable of translational movement within two mutually orthogonal directions. When the engraving process is to be performed, the engraving roller is held in contact with the workpiece, and as a result of a first translational movement of the workpiece mounting system in a first direction, a predetermined sector of the engraving roller is caused to contact a predetermined portion of the workpiece whereby a predetermined portion of the roller pattern is reproduced upon the workpiece. Movement of the workpiece mounting system in the second direction causes another section of the engraving roller to be aligned with another portion of the workpiece whereupon repeated movement of the workpiece mounting system in the first direction serves to reproduce a new portion of the pattern upon the new portion of the workpiece.
Patent ES-471576-A1 (ES)
Title: System for multi-mode control of a boiler feedpump turbine
IPC: F01D15/08
Filed: 1978-07-07
Abstract: A boiler feedpump turbine (BFPT) control system for controlling the rotating speed of a boiler feedpump turbine in a selected one of at least three control modes is disclosed. The boiler feedpump turbine is mechanically coupled to a boiler feedpump for governing the flow of feedwater pumped by the feedpump to a boiler. A boiler control turbine speed signal which represents the feedwater requirement of the boiler is provided to the BPFT control system from a conventional boiler feedwater control system. The flow of feedwater pumped by the feedpump is a function of the rotating speed of the boiler feedpump turbine which is controlled in a selected one of three modes in accordance with the adjustment of a speed set point. The three control modes include adjusting the speed set point in relation to a turbine speed demand signal generated within the BFPT control system only at values below the boiler control turbine speed signal, adjusting the speed set point in relation to the boiler control turbine speed signal, and overriding the adjustment of the speed set point by the boiler control turbine speed signal to permit adjustment of the speed set point by the turbine speed demand signal beyond the value of the boiler control turbine speed signal. Transfers between the control modes are performed automatically in response to a set of predetermined conditions and commands. The BFPT additionally provides for conducting an overspeed test which permits adjustment of the speed set point by the turbine speed demand signal in a predetermined range beyond a rated turbine speed value. This overspeed test function prohibits the speed set point from remaining above the rated turbine speed values at times when not conducting the overspeed test. The BFPT control system employs a closed-loop primary speed controller which calculates its turbine speed feedback signal from a selected one of two speed transducers. The other of the two speed transducers may be used if a malfunction is detected in the selected speed transducer. The BFPT control system further incorporates a degraded manual backup controller which assumes control responsibilities when a malfunction is detected which renders the primary controller inoperative.

Patent ES-474428-A1 (ES)
Title: A data processing system incorporating a bus
IPC: G06F13/374
Filed: 1978-10-23
Abstract: A digital data processing system includes an interconnection connected to the various elements each called a nexus, that constitute the system. For one element 32A to communicate with another element 32B, the one element, as a commanding nexus, seeks control of the interconnection and then transmits a command and address of a storage location in the other element when it receives control of the interconnection the other element sends to the one element a confirmation signal in response to receipt of the command and address. Control is then relinquished unless the one element is to send data to the other element whereupon the data is sent immediately. If data is to be retrieved, the other element retrieves the data, requests control of the interconnection and, when it receives control transmits the data onto the interconnection with an identification of the one element which was included in the command transmitted by the one element and has been temporarily stored in the second element. The one element then retrieves the data from the interconnection when it recognizes its own identification. If the other element is a memory element, it also contains a storage file for storing commands and data if it already is operating in response to another element command.

Title: Supplementary hydrostatic drive electronic control
IPC: B60K23/08
Filed: 1979-05-29
Abstract: An electronic control for a vehicle supplementary hydrostatic front wheel drive includes a rear sensor for providing a command signal representative of the speed of differential connected, engine-driven, main drive wheels. A front sensor provides a feedback signal representative of the speed of the hydrostatic drive motors. The command signal is modified to provide a modified command signal to be summed with the feedback signal to provide servo circuitry with a servo signal which is representative of the front wheels being driven 3% slower than the rear wheels. Electrically actuated, pressure responsive clutches allow the front wheels to overrun the hydrostatic drive motors until the slip at the rear wheels exceeds 3%, then the front wheels drive to supplement the main drive wheels. A selectable overspeed circuit is provided which can modify the modified command signal to provide a servo control signal which represents the front wheels being driven 1% faster than the rear wheels so as to provide a continuous, positive supplementary drive regardless of rear wheel slip. The servo control signal is processed through direction controllers which input the direction of the main drive wheels and which supply control signals to a servo actuator on a reversible hydraulic pump which powers the hydrostatic drive motors for drive in accordance with main drive speed and direction. Both the servo and overspeed circuits are connected to a hold circuit which activates and holds the overspeed circuit on to provide quick response when the direction of the main drive is changed.

Title: Winch for open-width wet treatment of textiles - using low liquor ratio applied in fan-shaped spray
IPC: D06B3/28
Filed: 1980-01-25
Abstract: Equipment for the continuous wet-treatment of textile fabric in open width with a low liquor ratio has a liquor spray producing a fan-shaped stream of liquor which impinges on the moving fabric at an acute, but varying angle, assisting the transport and layering of the material. The fabric passes through a U-shaped chamber in contact with the liquor, whence it is drawn off, mangled, and may be subjected to repeated treatments in additional, similar chambers. The process gives high-quality results on low liquor ratios of 1:3 and relatively low throughput speeds of 80-120 m/min. The treatment is uniform across the width of the fabric and free from danger of setting-in creases or over-working the fabric. Rinsing efficiency is considerably increased, giving savings in time, and in water and energy consumption.
