Abstract: ABSTRACT OF THE DISCLOSURE    A beam limiter circumscribes the interior surface of a vacuum vessel to inhibit collisions of contained plasma and the vessel walls.  The cross section of the material making up the limiter has a flatsided or slightly concave portion of increased width towards the plasma and portions of decreased width towards the interior surface of the vessel.          This configuration is designed to prevent a major fraction of the material sputtered, vaporized and blistered from the limiter from reaching the plasma.  It also allows adequate heat transfer from the wider to the narrower portions.  The preferred materials for the beam limiter are solids of sintered, particulate materials of low atomic number with low vapor pressure and low sputtering and blistering yields.

Abstract: DUAL DIRECTIONAL AND BRAKE LIGHT      CONTROL FOR TRAILERS      ABSTRACT OF THE DISCLOSURE:           A device for adapting combined brake and turn signal lights on a trailer to independent brake signal and turn signal lights on a towing ve-hicle has two circuits, one for each side, each circuit having a brake signal switch, such as a transistor, silicon-controlled rectifier or relay connected between the brake signal circuit of the vehicle and the filament of the combined brake and turn signal light on the corresponding side of the trailer.  The brake signal switches are selectively actuated by impulses received from the corresponding turn signal flashers on the vehicle, to block the brake signal current to the corresponding signal light on the trail-er.  In one embodiment of the invention, voltage-sensitive switches (e.g.SCR) are connected to brake switch transistors, and the left-hand and right-hand turn signal circuits on the vehicle are connected through diodes to the cor-responding signal lamps on the trailer, and also to their respective switches. When brakes are applied and turn signals simultaneously operated, the flash-ing turn signal triggers the voltage-sensitive switch on that side, causing the transistor to switch off, which prevents the brake circuit from lighting the combined lamp filament on that side while the filament is being flashed by the turn signal.  The lamp on the other side remains lighted by the brake circuit.  In another embodiment, relays or transistors are connected to the turn-signal circuits and brake signal circuits on each side of the towing vehicle in such a way that when one turn signal is operating the brake sig-nal for that side is blocked by the turn signal voltage, and is passed when the turn signal voltage is off.  Thus, the trailer turn signal lamp on the one side blinks at the same rate as the turn signal lamp on the vehicle, but 180° out of phase with the latter.

Abstract: ABSTRACT OF THE DISCLOSURE         A system for rapidly substituting one source of AC power for another is disclosed.  A solid-state gated electronic valve is coupled in circuit with a principal power source or "line" and the current through the valve is monitored.  Line voltage is also monitored and a timing signal produced to keep the system in synchronism with the principal power source.          When the source voltage decreases or changes abruptly, or if its phase drifts unacceptably, the difference detected between the source and a reference effects the termination of valve gating signals, and allows the application of synchronous enabling signals to a standby power source. If the solid-state valve is non-conducting the standby source starts immed-iately in synchronism with the previously-supplied load voltage.  If current is flowing in the valve, however, a commutating signal is produced which overrides the synchronous standby enabling signal to energize the standby power source with the proper polarity to extinguish current through the valve.  When the current decreases below the holding current value the standby source is caused to enter the synchronous mode.

Abstract: ABSTRACT      In spite of a very long experience, on world-wide scale, (probably were used in pre-Roman times), many and various existing theories as well modern studies with experiments, bulkheads' struc-tural problems remain highly indeterminate. Earth pressure is a primary function of the soil-structure factors. By applying the presented invention it is possible to adapt the minimum soil pressure against the anchored bulkheads. The various components of the struc-tural system can be basically dimensioned with predetermined factor of safety.     The adjustable anchored bulkheads' system can be applied to simi-lar anchored structures as well. By using this invention it is possible to achieve tremendous economy of material in construction of anchored bulkheads.
