Abstract: In a trailer train combination having a tractor, lead trailer and one or two more following trailers, an adjustable dolly under the front end of each following trailer provides for close coupling of the multiple trailers in end to end contact. Then the multiple trailers are lifted to inclined position causing the upper trailer or trailers to discharge its flowable contents out through the lower trailer in a self unloading operation. The dolly has a slidable fifth wheel assembly and self steering ground wheels which may be locked in straight forward positions. A cab controlled electric and pneumatic control system controls these and other functions in the dolly. The trailers may be equipped with walking floors for self unloading in level positions.

Abstract: A child proof container for storing dangerous articles such as medicines, poisons, hand guns, knives and the like. The container comprises wall structure defining a receptacle and an access opening. A closure provided with a finger hole is mounted across the opening. Finger operated latch means interconnect the closure member and the wall structure. The latch means is positioned apart from the finger hole a spaced distance predetermined to prevent latch operation by short fingered individuals.A combination finger guide and baffle is mounted on the closure member for guiding the finger into latching engagement and also for shielding the receptacle contents from finger contact. A mounting for the latch mounts the latter adjustably in selected positions toward or away from the finger hole as required to adjust the spaced distance therebetween to the finger length of the operator.

Abstract: A throwable, multi-sided emergency traffic warning marker. The marker body comprises a plurality of traffic-warning display faces preferably arranged in a tetrahedral configuration. Traffic warning indicia are present on each face, imparting visibility thereto. The marker assembly is contoured and proportioned to insure display of one of the display faces to oncoming vehicles when the marker is thrown, dropped or otherwise placed on a roadway surface.

Abstract: A trailer hitch guide provides a temporary, removable V-shaped fence partly embracing a hitch ball for guiding a trailer tongue into place to fit over the ball. The guide is provided as an attachment made up in part of a flat plate having a central opening for accommodating the hitch ball, and this opening is elongated fore and aft to enable selective positioning of the plate relative to the ball so as to assure a proper location of the other part, which is a hitch fence mountable on the plate. Attachment of the fence to the plate is effected by downwardly and rearwardly directed studs on the fence that removably fit openings in the plate, the shape of the studs counteracting the forward thrust of the trailer tongue during hitching and also enabling easy mounting and dismounting of the fence to and from the plate, which remains on the towing vehicle hitch structure as by welding or attaching bolts.

Abstract: A giant tripod assembly for long-range laser beam generators used particularly for controlling from a remote station the operation of grading machines, scrapers, mining equipment or the like. The tripod may be as much as 12 or 15 feet high. It mounts the laser unit at its upper end where the generated beam lies above the plane of intervening vehicles and other obstructions and hence may be transmitted over a range of as much as 1500 ft or more. The control for adjusting the direction of transmission of the laser beam is mounted an appropriate distance downwardly of the laser beam generator to render it accessible to persons standing on the ground.

Abstract: A landscaping bed divider for forming a boundary between adjacent landscaping areas comprises a continuous anchoring and dividing plate having opposite side faces along its upper margin, at least one tubular edge piece, and connecting means for connecting the tubular edge piece to one of said side faces, longitudinally thereof.

Abstract: An orthopedic cervical support collar comprising a piece of thick, absorbent cloth material folded lengthwise to form an elongated, multi-ply pad having a length sufficient to encircle the neck and provide an overlap. Stitching through the cloth plies, or other suitable ply interengaging means, maintains the plies in a flat, pad-forming condition. Releasable fastening means such as burr type ("Velcro") fasteners are mounted on the pad in the area of the overlap for releasably fastening together the overlapped pad ends when mounting the pad collar-wise on the neck of the user.A method of making the collar from a length of toweling or other thick, absorbent cloth material also is provided.

Abstract: Multiple sclerosis and other diseases are diagnosed by first coating a plasm protein-adsorbing surface with a patient's blood plasm protein in an electrolyte fluid, and measuring the streaming potential of the protein-coated surface. Next, a challenge material such as a fatty acid having from 6 to 24 carbon atoms is added to the protein in electrolyte fluid mixture to alter the electro-kinetic potential of the adsorbed blood plasm protein layer. The streaming potential of the altered layer then is measured. The streaming potential results thus obtained are compared with measurements of the streaming potential characteristic of a surface similarly treated, but using normal blood plasma protein.

Abstract: A suspendable, thermally insulating jacket for I.V. fluid bags. The jacket comprises a sheet of thermally insulating material enclosing the bag as it is applied in sick room use. A bag support hook and straps on the jacket support the I.V. bag within the sheet when the latter is in its bag-enclosing condition. A jacket support loop on the jacket support it on the I.V. pole or other support in the sick room. The jacket accordingly provides for maintaining the fluid contents of the I.V. bag at the desired temperature as they are administered to the patient.

Abstract: An acoustic headgear-sun visor assembly for use by pilots, users of Walkman-type radio and tape deck assemblies, users of noise attenuation devices and the like. The assembly comprises a headpiece including a flat band support member. A split bolt having a bifurcated shank receives the flat band support member. A sun visor is mounted on the split bolt in an angularly adjustable friction fit, enabling shifting it between operative and inoperative positions.

Abstract: A syringe holder permitting one-handed recapping of the syringe needle and thereby avoiding possibility of injury from needlestick.The holder comprises a support for the syringe body associated with a support for the needle cap. A clamp is provided for the needle cap support which releasably clamps the cap in place during use of the syringe. Accordingly the syringe needle may be withdrawn from the cap and recapped as many times as desired, using but a single hand. A sheath is associated with the assembly.

Abstract: An electrically insulative pipe hanger for supporting metal fluid conduits. The pipe hanger comprises a metal shank segment and an integral metal pipe-receiving hook segment merging with the shank segment through an inwardly facing throat segment. Overlying at least a portion of the hook segment is a sheath of electrically insulative, flexible plastic tubing positioned for bearing contact with the pipe and insulating the same from the hanger. The sheath includes a substantially half round segment overlying the throat segment of the hanger. The hanger is manufactured by pushing a length of flexible tubing having a half round leading end over the tip end of the hanger until the half round portion overlies the hanger throat segment.

Abstract: An insect trap, particularly a yellow jacket trap of improved efficiency has novel combination entryway and bait tray elements supported in its side walls. It also has provision for containing both liquid and solid insect bait in its bottom portion. Insects entering the trap after eating the bait, fail to find their way out, fly to exhaustion, and drown in the pool of liquid at the bottom of the trap.

Abstract: A line of sight aligning device for use with an optical instrument having a viewing opening requiring precise alignment with the line of a sight of the viewer. The device comprises a body member having an eye opening and nose recess in operative position relative to each other. Positioning means position the body member relative to the optical instrument with its eye opening aligned with the viewing opening of the optical instrument. On the front face of the body member, above the nose recess, is a straight edge positioned within the field of vision of the viewer and disposed substantially at right angles to the longitudinal axis of the nose recess in the body member.
