Patent ES-421895-A1 (ES)
Title: Automatic programming system for standardizing multiplex transmission systems
IPC: G21C7/18
Filed: 1973-12-29
Abstract: An automatic programming system for standardizing multiplex transmission systems to accommodate additional inputs. The plurality of inputs to be transmitted are respectively addressed from a central control unit which provides a second concurrent corresponding address to an output unit associated with the addressed input. The output unit is responsive to the second address to provide an enable signal to the control unit. Similarly, the control unit is responsive to the enable signal to process the corresponding input addressed into a desired output format and transmit the same to the corresponding output unit. If an address not associated with an input is generated by the control unit there will be no corresponding output unit to enable processing within the control unit, hence, the address will be ignored. Accordingly, the control unit can be designed to generate a number of addresses in excess of the number of inputs to accommodate expansion of the system by the incorporation of additional inputs and output units. The additional addresses, and any corresponding fault conditions activated, will thus be ignored until expansion of the system is desired. A specific application to nuclear reactor position indication is described which enables a standardized design to be incorporated regardless of the size of the reactor employed (i.e., the number of rods monitored).

Title: Earth moving machine bucket with pivotable sides
IPC: B66F9/12
Filed: 1974-07-16
Abstract: A bucket for use on an earth moving machine has a concave blade with an attacking edge at one transverse extremity. Two sides laterally border the blade forming an inner cavity of the bucket. The sides are both pivotally mounted on the blade at axes parallel with the attacking edge but at the opposite transverse extremity of the blade. Springs urge the sides to pivot towards positions in which they provide a bucket cavity of maximum volume. When the blade is forced into material to be excavated, the sides are swung back against the spring force without themselves penetrating the material, thereby reducing the effort required to operate the bucket. On lifting the bucket out of the material, the sides swing back trapping the excavated material. The springs may comprise torsion bars.

Title: Process for manufacture of detergent powders
IPC: C11D11/02
Filed: 1977-11-24
Abstract: The invention relates to the preparation of spray-dried powders of low bulk density. Fabric washing powders containing nonionic surfactants as the major or sole detergent-active species have unacceptably high natural bulk densities (about 0.6 g/l). It has been found that the incorporation of certain alkenyl succinate salts into the crutcher slurry can reduce the bulk density of the resultant spray-dried powder. There is also a need for absorbents of low bulk density for manufacturing nonionic-surfactant based powders by dry-mixing routes and it has been found that suitable absorbents can be prepared by adding alkenyl succinate to a slurry of the chosen ingredients and spray-drying.

Filed: 1978-03-17
Abstract: The container with the exchangeable magnetic tape cassette located therein comprises a rectangular housing (1) and a slide-in unit (2), which can move along a narrow side of the housing and receives the tape cassette, as well as a compression spring (3), which acts between the rear wall (23) of the slide-in unit and the rear side (8) of the housing. After the release of a holding device (31, 35), the compression spring pushes the slide-in unit together with the tape cassette by an amount out of the housing into an open position, in which the tape cassette can be removed unhindered from the container. The push-in unit has the form of a four-sided frame which leaves the bottom (10) of the housing free and which at least partially embraces the tape cassette lying on the bottom. In the open position, at least the frame part protruding out of the container takes up an oblique position with respect to the bottom of the housing, releasing the cassette on all sides, so that one-handed operation for loading and removal is possible. It is also advantageous that the container allows music tape cassettes to be loaded in four different orientations and coincides in its dimensions with conventional cassette boxes.

Patent ES-479556-A1 (ES)
Title: Control systems for electric generators
IPC: H02P9/08
Filed: 1979-04-11
Abstract: The excitation winding of an alternator is energized through a silicon controlled rectifier (SCR) from the output of the alternator. The SCR is bypassed by a constant current network to allow the alternator to start up even with no excitation current, when the alternator output voltage is due to residual magnetism alone, this network can pass a current into the excitation winding, and build the current up gradually to a value above the latching current of the SCR. When this has happened, the SCR can latch on after being fired, and takes over control of the excitation current. Because the network is a constant-current network rather than a purely resistive network, it can be designed to pass sufficient current at low alternator output voltages, without having to dissipate excessive power at higher output voltages. Also, when the output voltage is at its normal operating value, the constant-current network is rendered non-conductive, to avoid the excessive power dissipation which might occur at full voltage. A protective circuit is also included, which is tripped if the voltage on the excitation winding should become excessive as the result of an overload. The tripping takes the form of the turning-on of a programmable unijunction transistor (PUT), which remains on, drawing current from a smoothed supply taken from the alternator output, until the alternator speed is reduced to a very low value. At this low speed, the constant-current network cannot pass sufficient current to allow the alternator output voltage to build up, so that the output voltage does not suddenly increase when the PUT turns off.
Patent ES-479642-A1 (ES)
Title: Self-regulating deflection circuit with resistive diode biasing
IPC: H04N3/16
Filed: 1979-04-17
Abstract: A self-regulating deflection circuit includes a first inductor and switching transistor coupled across the unregulated voltage supply. A damper diode, retrace capacitor and second inductor are coupled in parallel, and the parallel combination is coupled across the transistor by a first rectifier poled to prevent current from flowing from the first inductor to the second inductor. A second rectifier is coupled between the first and second inductors for transferring energy from the first inductor to the second during the retrace interval. A control circuit coupled to the second inductor and to the base of the switching transistor controls the time during the first half of the trace interval during which the transistor conducts to allow energy to be stored in the first inductor. A storage capacitor is coupled in series with the second rectifier. Charge accumulation on the storage capacitor and resultant blocking of the second rectifier is prevented by a resistor coupled across the storage capacitor.
