Abstract: A multiple fluid pumping system uses two or more fluid pumps each driven by a pneumatic piston or plunger and cylinder combination whose piston top stroke and bottom stroke positions are detected by reed switches in combination with a magnet attached to the piston. The top stroke reed switches are connected in series with one side of a two position pneumatic solenoid valve while the bottom stroke reed switches are connected in series with the other side of a two position penumatic solenoid valve. The circuit is designed to prevent one of the pistons from changing the direction of its stroke prior to the other piston reaching the end of its stroke. A further embodiment utilizes a magnet mounted on one pneumatically driven piston or plunger and a pair of reed switches mounted on the other penumatically driven piston or plunger to prevent one piston or plunger from moving faster or slover than the other piston or plunger.

Abstract: An ionizable material is injected in the shape of concentric jet and cylindrical column of gases from a cathode-nozzle toward an anode and subjected to a very short, high voltage pulse of electrical current having sufficient magnitude to create a high magnetic field which implodes the cylindrical column of ionizable material and compresses the central jet of ionizable material to a very dense plasma that is relatively stable longitudinally that can be used as a gain medium for a long wave length X-ray laser.

Abstract: A brake light warning system for a motor vehicle causes the brakes lights to flash in a manner to attract the attention of a driver to the rear of the vehicle and provide a more effective warning of a slow down or stopping of the vehicle especially during foggy days or nights and when the view of a vehicle is partially obscured. Upon application of the brakes the brake lights are first caused to flash rapidly for 2 or 3 times for a first interval of time followed by prolonged "on" periods interrupted periodically by a short "off" period followed by a short "on" period followed by a short "off" period for a second interval of time as long as pressure is applied to the brake pedal of the vehicle.

Abstract: An elongated roadway barrier having an upright wall attached to a base support adapted to engage a roadway surface is provided with retractable wheels which are lowered simultaneously with the application of a lateral force to the barrier using a cable system attached to drive motors located proximate the side of the roadway or using a self-propelled drive mounted in the barrier.

Abstract: A retaining wall utilizes an ordered array of modular blocks each having a horizontal cross-section defining a double "T" shape, the top of the double "T" defining a vertical planar member having a horizontal length greater than the vertical height with the stem of each "T" defining a generally planar leg member having a height the same as the vertical planar member. A hole is provided vertically through each leg distal the vertical planar member and adapted to receive a tension rod for tying the assembled blocks together. The "T" shaped blocks are vertically arranged in staggered courses with the holes of the legs in the course above vertically aligned with the holes in the legs in the course below. The lower end of the tension rod is adapted to be anchored in the concrete footing supporting the retaining wall.

Abstract: A security device for a door utilizes a first bracket member attached proximate one jamb of a door with a chain attached to said bracket and adapted to be fastened to a second chain engaging bracket member fastened proximate the other jamb of the door. The chain engaging bracket generally defines a U-shaped member having a first leg, a second leg and a saddle. The first leg is adapted to be attached to the jamb or building frame adjacent the door. The second leg comprises slots adapted to receive the links of a chain proximate the end of the legs. The saddle also comprises a slot adapted to receive a link of the chain. The chain is wrapped around the chain engaging bracket whereby a link of the chain is first received and engaged in the slot in the saddle. Then another link of the chain is received and engaged in the slot in the leg distal the slot in the saddle. The path of the chain then passes up for a link to be received and engage a slot in the leg proximal the slot in the saddle.

Abstract: A pair of elongated support leg members are configured to engage and hold an object by clamping around a narrow portion of the object, with the ends of the leg members defining inverted hooks which are adapted to engage and be supported by a pair of spaced apart rods or support members.

Abstract: Three or more vertical posts or decorative support members are connected to the ends of three or more articulable, serially connected linkage members by a base support pin or member proximate the bottom end of each of the vertical posts through the holes in the ends of the linkage members. The linkage members are disposed parallel to the supporting surface having their free and overlapping ends connected between the bottom end of the vertical post and the base support pin. The vertical posts are each provided with a receptacle for holding a decorative or utilitarian object proximate the top thereof. The vertical posts can be of various lengths to achieve a variety of decorative effects.

Abstract: An ionizable material is ejected in the shape of a cylindrical column from a cathode-nozzle toward an anode and subjected to a very short, high voltage pulse of electrical current having sufficient magnitude to create a high magnetic field which implodes the cylindrical column of ionizable material to a very high density plasma that emits long wave length x-rays. Accurate and reliably reproduced x-ray bursts are provided through coupling of the cathode and anode to the high voltage pulse generator without substantially degrading the pulse. The conductors between the pulse generator and the cathode and anode are of a configuration whereby a magnetic field is used to prevent the electron losses by tapering the spacing between feed conductors and shaping the feed conductors so that space-charge flow is retrapped and made usable.
