Patent ES-420579-A1 (ES)
Title: Loader linkage
IPC: E02F3/34
Filed: 1973-11-15
Abstract: The bucket control linkage of a tractor loader includes a vertically disposed lever pivotally connected intermediate its upper and lower ends to a boom. A dump link is interconnected between the lower end of the lever and the upper rear of the bucket. The bucket control linkage also includes a bucket operating jack having its front rod end pivotally connected to the upper end of the lever and its rear cylinder end pivotally connected to a special linkage. The special linkage includes a pair of pivotally interconnected links, one of which is pivotally connected to the boom and the other of which is pivotally connected to the tractor frame at a point spaced forwardly of the pivot connection between the boom and the frame. The special linkage to which the cylinder end of the bucket operating jack is connected, causes the bucket to automatically retract as the boom is raised through an initial angle toward its level position and then will cause the bucket to pivot forwardly relative to the boom to maintain the bucket in a proper material retaining altitude in relation to the ground. The various components of the bucket operating linkage are in line with the longitudinal vertical plane of the boom for ideal component stress distribution. The bucket is retracted by introduction of hydraulic fluid to the cylinder end of the dumping jack whereby the greatest possible breakout force is achieved by the jack. The rod end of the hydraulic jack is pressurized to dump the bucket thus giving the shortest possible dumping time. The connections between the bucket operating linkage and the frame of the tractor are relatively low thereby affording good operator visibility and desirable loader frame stress distribution.

Patent ES-471020-A1 (ES)
Title: Regulation circuit
IPC: G05F1/66
Filed: 1978-06-21
Abstract: A regulation circuit for providing timing gate signals to the dc power section of a power supply, the regulation circuit utilizing phase angle conduction of a programmable unijunction transistor. The conduction angle is determined by the occurrence of the cycles of the ac source voltage unless earlier conduction is determined by the sensed dc voltage. Early conduction occurs when the control voltage to the PUT is allowed to build up beyond a predetermined level when the sensed dc voltage is low. When the sensed dc voltage is high, an electronic switch closes to discharge a storage element to prevent control voltage build up and, hence, early conduction. Ac source voltage failure also causes closing of the electronic switch to prevent undue regulation of the power section output at such times and to permit storage capacitors therein to maintain a dc output until source voltage is reestablished. Soft start elements in the form of long time constant components ensure against the application of peaked voltages during initial start up and in the presence of power surges.

Patent ES-476750-A1 (ES)
Title: Infra red light emissive devices.
IPC: H01S5/323
Filed: 1979-01-11
Abstract: In (Sb0.1As0.9) light emissive diodes and lasers are grown on Ga Sb substrates to give lattice matching. Ga Sb has higher band-gap, high refractive index therefore gives electrical, but not optical, confinement required for laser action. Both confinement types provided by sandwiching active layer between layers of (Al0.6Ga0.4)Sb. In (Sb0.1As0.9) emits at approximately 4 mu m, but emission can be shifted by increasing the proportion of In Sb and restoring the lattice match by the addition of another compound semiconductor e.g. Ga As for longer wavelength emission of In P or Al As for shorter wavelength emission.
Patent ES-477242-A1 (ES)
Title: Push button mechanism for controlling a contact unit
IPC: H01H13/58
Filed: 1979-01-29
Abstract: A push button mechanism includes a housing (1) including a push button control key (2) and microswitches (4) actuated by pushing the key. There are two common modes of push button operation: either a non-locking operation in which the position of the switch contacts corresponds to the position of the key or a locking operation in which pushing the key changes the position of the switch which then remains in the new position after the key is released. From the manufacturing point of view it is desireable to provide a single mechanism which can act in either mode depending on the position of a selection component (7). From the user's point of view it may be advantageous to be able to change the mode of a switch which is already installed and wired. The present invention provides an operating key which may be withdrawn from the mechanism through the end face of the housing. The key carries a selection finger (7) for actuating a locking mechanism (8). For non-locking operation the finger is turned into a recess in the key while for locking operation it projects forwardly of the key. When the key is withdrawn it is simple to change the position of the finger.

Patent ES-485687-A1 (ES)
Title: Fuel line injection sensor
IPC: F02M65/00
Filed: 1979-11-05
Abstract: A rugged and inexpensive sensor is disclosed for monitoring fuel injection characteristics such as injection pulse timing and width. A clamp is provided with hand grips and expandable jaws for quickly coupling to a fuel injection line. The jaws are biased into engagement with the line but are easily opened for releasing the clamp by urging the hand grips together. A transducer mounted on the clamp senses mechanical vibration caused by pressure pulsations in the line. The transducer is connected to circuitry for providing an output when the signal level from the transducer exceeds a threshold level. The sensor is self-compensating with the threshold level determined automatically from the maximum signal from the transducer. Therefore, different injection lines can be monitored with no manual adjustment of the clamp or circuitry even though the output of the transducer may vary from line to line.

Patent ES-8206319-A1 (ES)
Title: Power steering system.
IPC: B62D5/09
Filed: 1981-11-02
Abstract: A power steering system, particularly advantageous for use on electric powered vehicles, in which the hydraulic pump operates only when steering commands are given. Torque applied to the steering shaft by rotation of the steering wheel is translated to axial stress on a thin walled tube, the direction and intensity of which depend on the direction and amount of steer angle change commanded. The axial stresses are detected by strain gages, and the motor which powers the hydraulic pump is activated only when stress is detected. Manual steering inputs enter the pump on one side, and the powered servo motor inputs enter on the opposite side, thus permitting the vehicle to be steered by manual input alone if the powered input fails. The components of the system are arranged in coaxial alignment, providing a compact system with improved heat dissipation qualities.
