Patent ES-398415-A1 (ES)
Title: Effluent cooling in a hydrocracking and hydrodesulfurizing process
IPC: C10G65/12
Filed: 1971-12-28
Abstract: A residue-containing petroleum fraction, 50 percent boiling above 1,000 DEG F, is hydrocracked and then hydrodesulfurized. During the onstream period, the conversion level of material boiling above 1,000 DEG F is maintained substantially constant while the sulfur content of the hydrocracked effluent increases. The sulphur content of a product fraction is maintained substantially constant by gradually increasing the hydrodesulfurization temperature. The effluent from the hydrocracking reaction is cooled by adding an aromatic-rich fraction and the cooled mixture is passed to the desulfurization reaction.
Patent ES-418980-A1 (ES)
Title: Signal gate circuit
IPC: H03F3/72
Filed: 1973-09-21
Abstract: A differential circuit including first and second differentially connected semiconductor devices and a third semiconductor device connected in series between the common terminal of the differentially connected devices and one of the power supply terminals. The series connected device is non-conductive between gating pulses, so no current flows through any of the semiconductor devices except during gating pulses. The information signal to be gated is applied to the series-connected device, and the gating signal is also applied to this device and to one of the differentially connected semiconductor devices. For at least part of each gating pulse, the signal to be gated is amplified by both the series-connected device and one of the differentially connected devices. At the beginning and end of each pulse, the other differentially connected device may be conductive to act as a virtual short circuit to prevent the one differentially connected device from amplifying any signals which are within a gating pulse interval but are not supposed to pass through the gate circuit.

Patent ES-421821-A1 (ES)
Title: Electric circuits particularly for automatic battery charging apparatus
IPC: H02J7/10
Filed: 1973-12-27
Abstract: Automatic battery charging apparatus is arranged to test the battery voltage at intervals of about 15 minutes, and to continue charging only if the voltage is below 2.3 volts per cell. If the voltage is higher, charging is suspended until the voltage has fallen to 2.3 volts per cell. The time needed for this fall to occur is monitored, and when on two occasions a comparison has indicated that a fall time is less than 5 percent greater than the preceding fall time, the main phase of the charge is terminated and a topping-up phase started. The apparatus is also arranged to stop charging if the battery voltage rises to 3.6 volts per cell, and a voltage doubler is arranged to raise the terminal voltage to this level if the battery is removed, so turning off the charge.

Title: Circuit interrupter with ground fault trip control
IPC: H01H3/16
Filed: 1976-04-29
Abstract: A circuit interrupter having an associated control system which senses overload current or ground fault current and causes an appropriate tripping of the circuit interrupter.

In addition, tripping energy for causing the circuit interrupter to open due to a ground fault condition is derived from the ground fault current.
Patent ES-448130-A1 (ES)
Title: Motor control systems
IPC: H02H7/085
Filed: 1976-05-21
Abstract: The control device is allocated to a DC motor which can rotate in opposite rotation directions and is used as a drive for components which can move into two limit positions, especially for opening and closing garage doors. In this case, switching devices (10, 16) are provided for the DC motor, which switching devices switch said motor off and on and/or reverse the direction of the motor current and hence the rotation direction of the motor. An overcurrent switching appliance (12) trips in response to current surges which occur when the load on the motor increases, especially during forced braking of the motor in the limit positions of the component or if an obstruction is present in the movement path. The switching devices (10, 16) have an on/off switch (16) and a switching appliance (10) which operates in a stepped manner and can be switched into an "interrupt" switching position whenever the overcurrent switching appliance (12) trips and into a "motor current on" switching position whenever the on/off switch (16) is operated, in accordance with the following switching cycle: interruption - motor current on and anticlockwise running - interruption - motor current on and clockwise running. As a result of this arrangement, limit switches are obviated and hence their adjustment and maintenance work. At the same time, reliable protection against overloading the DC motor is achieved.

Title: Apparatus for twisting and guiding stock into roll grooves
IPC: B21B39/20
Filed: 1976-12-09
Abstract: Apparatus for twisting and guiding metal stock into roll grooves, comprises a guide mounted in front of such a groove. The guide has a through path from which the stock emerges from the guide and passes to the groove, and a feed path disposed to one side of the through path. The feed path is defined by a funnel-shaped member having an opening therethrough of about the same size and shape as the stock to be fed, and which is mounted for swinging movement between two positions, in one of which it is out of line with the through path and in the other of which it is in line with the through path. The stock is fed through the swinging member in the out-of-line position and contacts a cam surface which moves the stock and hence the swinging member, into line with the through path, thereby twisting the stock about 90 DEG . After the stock is passed, the swinging member returns by gravity to its out-of-line position.

Patent ES-468917-A1 (ES)
Title: Automatic loader for charging fermented dough pieces into bakery oven - has successive conveyor bands with alternative common and independent drives
IPC: A21B3/07
Filed: 1978-04-18
Abstract: The loader is of the type which automatically transfers a predetermined number of fermented dough pieces from a prover to the oven. The loader comprises two conveyor bands arranged in succession between the prover and the oven. The first conveyor receives dough pieces from the prover and transfers them to the second conveyor. The second conveyor discharges the dough pieces into the oven. The drive shafts of both conveyors are driven via individual free-wheel sprockets from a drive transmission common with the oven conveyor. This means that the drive to both conveyors is normally synchronised with that of the oven conveyor. Each conveyor also has an independent drive motor and transmission so that either or both conveyors may be driven faster than the synchronous speed by over-riding the free wheel sprocket clutches.

IPC: D01H5/38
Filed: 1979-04-26
Abstract: A method of and apparatus for regulating out variations in the sliver weight on processing machines such as cards, carding engines, draw frames and the like wherein a first measuring device measures either the absolute cross-section or the relative variations of cross-section relative to a predetermined fixed desired value of a fibre sliver issuing from the machine. The first measuring device forms a corresponding first test signal. An additional measuring device is arranged at a point upstream of the first measuring device with respect to the direction of travel of the fibre material.
