Patent ES-448141-A1 (ES)
Title: Monitoring system for voltage tunable receivers and converters utilizing an analog function generator
IPC: H03J5/02
Filed: 1976-05-21
Abstract: A system for monitoring the channel to which a remotely located voltage tunable receiver or converter is tuned includes a comparator for comparing the magnitude of the tuning voltage with an internally generated reference voltage to determine the channel number. The reference voltage is generated by a counter driving a linear digital-to-analog converter. The output of the digital-to-analog converter is modified with an analog function generator to provide a piecewise linear approximation of the receiver tuning voltage versus channel number characteristic. A window comparator is utilized to compare the output of the function generator with the tuning voltage and to stop the counter and transfer the contents of the counter to an output circuit when the magnitude of the reference voltage approaches that of the tuning voltage. The contents of the counter at the time the counter is interrupted is indicative of the channel number of the station being received.

Title: Pump and motor assembly for use in regulating a flow of fuel from a source of fuel to an operating chamber of an engine of a vehicle
IPC: F04C15/00
Filed: 1977-12-02
Abstract: An improved pump and motor assembly is utilized to regulate a flow of fuel to an internal combustion engine. All of the fluid connections to the pump are connected with one end of the assembly. The pump and motor are both enclosed within a one-piece casing having a tubular side wall which is integrally formed with an end wall. The end section to which all of the fluid connections for the pump are made, is connected across the open end of the tubular side wall. To provide for the removal of vapor bubbles from the fuel, fuel supplied under pressure from the tank flows through an inlet cavity which circumscribes the pump and has an axial extent which is equal to the length of the pump. In addition, a screen at the inlet of the pump itself blocks the flow of vapor bubbles from the inlet cavity to the pump. The forces applied against opposite sides of the moving components of the pump by the inlet fluid are substantially balanced. Fluid pressure pulses in fuel discharged from the pump are dampened in an outlet cavity by a seal member which sealingly engages an outer cheek plate of the pump to separate the inlet and outlet cavities. A single spring element is utilized to perform the dual functions of pressing the seal member into engagement with the outer cheek plate of the pump and to press the outer cheek plate and cam ring against the inner cheek plate.
Patent ES-465304-A1 (ES)
Title: Controlled flow cooling system for low weight reciprocating engine
IPC: F01P3/02
Filed: 1977-12-21
Abstract: A light metal die-cast head and cast iron block employ a low volume cooling system which cooperates with the differing thermal conductivity properties of said head and block. The cooling concept eliminates the conventional intricate water jacket and replaces it with continuous grooves which wrap hemi-cylindrically about each combustion cylinder in a thinly spaced relation. The grooves are exposed along their length at the deck surface of either the head or block. The total fluid mass in the system is reduced to as little as 1/5. There are two such grooves in the block which (a) extend from one end thereof to the opposite end, (b) are on opposed sides of the cylinder galleys and (c) have substantially no transverse flow in order to promote laminar or controlled flow. There is a critically located straight drilled passage along with two such grooves in the head, the combination of which is restricted in throat area when compared to the throat area of the grooves in the block this results in a high velocity flow in the head and a low velocity flow in the block when they are connected in series flow relation. The straight longitudinally drilled passage (which may include one or more of such passages) is located in the head separating the exhaust and metal valve guides the passage has a throat area equal to or less than the throat area of either of the grooves in the head. Heat extraction is more easily and flexibly programmed to achieve not only a more uniform wall temperature throughout the head and block, but permit a desirably slightly higher average wall temperature than conventional light metal heads for improvement in fuel economy and thermal efficiency.
