Title: Neutron accelerator tube having improved ionization section
IPC: G21K5/08
Filed: 1981-04-30
Abstract: A neutron accelerator tube having a target section, an ionization section, and a replenisher section for supplying accelerator gas to the ionization section. The ionization section is located between the target and the replenisher section and includes an ionization chamber adapted to receive accelerator gas from the replenisher section. The ionization section further includes spaced cathodes having opposed active surfaces exposed to the interior of the ionization chamber. An anode is located intermediate the cathodes whereby in response to an applied positive voltage, electrons created by field emission are transmitted between the opposed active surfaces of the cathodes and produce the emission of secondary electrons. The active surface of at least one of the cathodes is formulated of a material having a secondary electron emission factor of at least 2. One cathode member located in the tube adjacent to the replenisher section may have a protuberant portion extending axially into the ionization chamber. The other cathode spaced from the first cathode member in the direction of the target has an aperture therein along the axis of the protuberant portion. An annular magnet extends around the exterior of the ionization chamber and envelops the anode member. Means are provided to establish a high permeability magnetic flux path extending outwardly from the opposed poles from the magnet to the active surfaces of the cathode members.

Patent ES-8305136-A1 (ES)
Title: Apparatus for making copies at different magnifications.
IPC: G03G15/041
Filed: 1981-11-03
Abstract: A reproduction apparatus for producing copies of a document selectively at one of a plurality of copy image magnification ratios. The apparatus includes a microprocessor for control of the optical components for variable magnification, the control including a bidirectional AC motor (41) a reference potentiometer (42), an analog to digital (A/D) converter (98), and triacs (94, 96) for driving the motor. The potentiometer voltage represents the present position of the optical components in the reproduction machine. The position of the optical components determines the actual magnification ratio of images. Upon selection of a particular magnification ratio, a digital position word from memory (99) corresponding to the selected magnification ratio is compared (102) to the optical component current position voltage converted through the A/D converter (98). Depending upon the error signal generated by the compare operation, a run bit is set to activate the motor in the direction to minimize the error signal and position the optical components to achieve the magnification ratio selected. As the optical components near the desired locations, the motor is selectively pulsed to progressively decrease the duty cycle of operation. For example, the duty cycle of operation is decreased from 100 percent to 70 percent, 50 percent, and 30 percent to slowly position the optical components and minimize inertia effects.

Patent ES-8406883-A1 (ES)
Title: Container sterilization apparatus and method.
IPC: B65B55/10
Filed: 1983-04-14
Abstract: The disclosure illustrates and describes a sterilization apparatus and method for sterilizing the interiors of paperboard containers, wherein such apparatus and method are effective through the mandrel assembly on which the container bottom closures are formed and sealed. This is accomplished by forming longitudinal channels through each mandrel and connecting same to separate compartments formed within the hub, and providing means for communicating a suitable sterilant fog through respective compartments and channels at the station where each bottom-formed container is stripped from its respective mandrel. The usual fast stripping action tends to create a vacuum within the container which aids the dispersement of the fog onto the entire inside surface of the container, sterilizing it prior to the subsequent filling operation.

Patent ES-8506473-A1 (ES)
Title: Separation of fluid cracking catalyst particles from gaseous hydrocarbons
IPC: B01J8/22
Filed: 1983-12-21
Abstract: Catalyst and hydrocarbon vapors are separated in a cyclone zone attached to the discharge of a riser cracking operation. Vortex stabilizing means separating the cyclone zone from a stripping zone allows stripping gas from said stripping zone to be passed upwardly into said cyclone zone countercurrent to the downward flow of catalyst, thereby improving the separation and stripping of gaseous hydrocarbons from separated catalyst. The combined cyclone-stripping zone reduces catalyst hydrocarbon contact time, thereby improving gasoline yield and olefin content, decreasing gas make, and reducing coke deposits.

Patent ES-8606753-A1 (ES)
Title: Analog-to-digital encoder and digital-to-analog decoder.
IPC: H04B14/06
Filed: 1984-10-05
Abstract: In the encoder an audio input signal is firstly given an adaptive pre-emphasis characteristic by a pre-processing circuit (16) and is then converted to a digital signal for transmission by a delta-modulator (22). In order to minimise the digital bit rate the delta-modulator (22) is rendered adaptive by deriving a step-size control signal in a circuit (18) responsive to the slope of the input signal, and applying the control signal to vary the step-size of the delta-modulator (22). The bandwidth of the control signal is limited to say 50 Hz by the step-size circuit (18) itself or a subsequent low pass filter (24) in order to render the encoder insensitive to random step-size errors. The slow response of the control signal is compensated for by a delay circuit (20) preceding the delta-modulator (22). The corresponding decoder comprises an adaptive delta-modulator and a circuit complementary to the pre-processing circuit (16). In order to keep the decoder as simple as possible it has no step-size derivation circuit. Instead, the step-size control signal is transmitted in conjunction with the main digital signal by way of an analog to digital converter (26). In the encoder a complementary digital to analog converter is followed by another bandwidth limiting filter to reduce the effect of transmission bit errors. The slow response of the decoder control signal is compensated for by transmitting the step-size information from the encoder with a time advance relative to the main digital signal.
