Patent ES-449470-A1 (ES)
Title: Sheet stacker
IPC: B65H31/28
Filed: 1976-07-01
Abstract: A lift table is movably mounted on a frame adjacent to one end of a conveyor belt which deposits sheets of corrugated board or the like on the lift table. As the sheets pile up on the lift table, the table is automatically lowered so that the top of the stack remains below the level of the conveyor belt. When the stack reaches a predetermined height, the conveyor belt is blocked to interrupt the delivery of sheets, and the stack is moved off the lift table by live rollers thereon. The lift table is then raised at a relatively high speed to the level of the conveyor belt, which is subsequently unblocked to start a new stack. The lift table has a pair of torsion bars journalled to opposite sides of the lift table parallel to the table top. Four pairs of sprockets are rigidly attached to the corresponding ends of the torsion bars. Two pairs of leveling chains are attached at both ends to the frame and operatively engage corresponding sprockets to rotate the torsion bars and maintain the lift table level as it is raised and lowered. The lift table is raised and lowered by hydraulic cylinders which are linked to the lift table by chains. The hydraulic cylinders are mounted within the upper frame members to conserve space.

Patent ES-462778-A1 (ES)
Title: Fuel injection system with augmented temperature sensitive fuel enrichment for transient engine loads
IPC: F02D41/34
Filed: 1977-09-29
Abstract: A fuel injection system for a spark ignited, internal combustion engine employs sensors which measure engine operating parameters to control the duration of actuating pulses applied to at least one fuel injector. One of the sensors measures engine temperature and the pulse duration is increased at lower engine temperatures to compensate for the lower volatility of the fuel at such lower temperatures. The output of a manifold vacuum sensor is differentiated to derive a signal proportional to the rate of increase of engine load and that is used in combination with the engine temperature sensor to increase the duration of an injector actuating pulse in amounts proportional to the rate of increase of engine load. The amount of increase in duration of the pulse varies inversely with engine temperature. This allows the enrichment of the fuel charge which normally occurs as an inverse function of engine temperature to be maintained at a level which may produce a leaner steady state air to fuel ratio during engine warm-up and to provide additional enrichment of the fuel charge during periods of increase transient engine load to provide reduced exhaust emissions during warm-up without stalling.
Patent ES-464792-A1 (ES)
Title: Setting and controlling desired redox potentials in gases
IPC: F27B9/40
Filed: 1977-12-06
Abstract: Method for controlling desired redox potential in hydrogencontaining protective gases used in high-temperature furnaces in powder-metallurgical processes. A sample of the protective gas is withdrawn from the furnace and the redox potential of the sample measured at the high temperature to produce treated bodies of good quality. Humidifying the gases blowing through the furnace is employed to erase or minimize a deviation of the redox potential of the sample from a predetermined redox potential. Ax oxygen-hydrogen mixture may be obtained by electrolysis of water as a function of the measured redox potential and this mixture may be used for humidification. In this manner good quality end products are assured despite fluctuations in throughput and properties of material entering the furnace.

Abstract: A steering valve arrangement for a hydraulically operated steering system of a vehicle has two spring-loaded, seat-type inlet valves 22a and 22b which are closed in the neutral position of the steering system so that the supply from a pressure medium source to the respective working chambers of an adjusting motor is cut-off. The valve members 38 of the inlet valves co-operate with valve seats 24 formed in an outer rotary member 12 which is resiliently connected via a torsion bar 16 to an inner rotary member 14 in operative connection with the steering wheel of the vehicle. Each valve members 38 is urged on to its valve seat 24 by a respective bow-like spring 36 accommodated in a substantially annular chamber 18 which is formed in the outer rotary member 12 and which constitutes a discharge chamber in communication with a working chamber of the adjusting motor. The valve 22a can be opened, on rotation of the inner member 14, via a tappet 46 which by way of a fine control spring 40 acts on the end of the spring 36. In operation the valve spring 36 counteracts the force produced by pressure drop at the valve 22, and the members 14, 46 operatively connected to the vehicle actuating means (steering wheel) so engage the valve springs 36 that with a steering movement the force of the valve spring 36 corresponding to the steering direction is reduced.
