Abstract: A tube hanger for selectively supporting at least two different sizes of tubes from a mounting surface comprises a unitary body of flexible, resilient material having a body portion sized to extend transversely across a tube to be supported by the hanger. The body portion has a base end generally for abutment with a support surface and an arm with a tip end extending outwardly from the base end in a semi-circular arc segment. The arm defines a partially enclosed cavity sized for receipt of a first size of tube, such as 7/8 inch o.d. tubing. A supplemental finger extending outwardly from the arm and into the cavity substantially concentrically with the arm cradles and grips a second size of tube of lesser diameter than the first size of tube. The tube hanger snap-fits and snugly maintains its position about both sizes of tubing for one handed installation, freeing the installer from having to hold the hanger about the tubing while fastening the hanger to a support, such as an overhead joist.

Abstract: A spring contact twisting electrical contact spring probe for testing electrical printed circuit boards includes a barrel having a spring seating end and an open end, a compression spring seated in the closed end of the barrel, and a plunger inserted into the barrel. The plunger includes a tail section, connected to a twister section comprising a square rod twisted along its longitudinal axis, and a shaft or probe section that protrudes from the barrel and includes the probe tip. Four crimps in the barrel retain the plunger inside the barrel and interact with the helical crests on the twister section to cause the plunger to rotate along its longitudinal axis as it reciprocates within the barrel. The twister section is retained entirely within the barrel at all times. The rotating plunger tip has edges that scrape off contaminants or coatings on the test sites of the circuit boards to obtain a sufficient electrical connection.

Abstract: A drive-on vehicle supporting arrangement for use with a floor anchor system includes a pair of parallel, spaced vehicle supporting treadways, each of which includes vehicle support stands secured to floor anchors to affix the support stand to the floor and clamps to connect to the undercarriage of a vehicle.

Additionally, a front treadway extends forwardly from the front vehicle support stand and a rear treadway extends rearwardly from the rear vehicle support stand and are supported by treadway support stands. A ramp leads to the rear treadway so that the repairman can drive a vehicle onto the treadway surface, elevate the vehicle, if necessary, by portable jacks and secure the vehicle atop the support stands. Thereafter, the treadways may be removed for clear access to the underside of the vehicle to facilitate repair.

Abstract: An adjustable corner strip for joining adjacent concrete form panels into a column mold includes spaced diverging wings with slots to retain adjustment screws for adjusting the divergence of the wings, and thus the panels. The corner strip permits easy and rigid squaring of forms. A chamfer strip includes a chamfer face and an integrally formed tail section extending outwardly of the strip and adapted to fit into the channel formed along the mold side rail. The adjustable corner strips bring the chamfer strips into tight mating engagement with the interior surfaces of the mold panels, preventing leakage of cement between the chamfer strips and the mold panels.

Abstract: A lamp assembly for surgery and the like includes a ceiling mounted track having opposed internal channels, a carriage assembly that rides in the track and that is connected to a depending tubular stem which terminates in a control head having a lighthead fastened to it. A switch on the control head energizes a solenoid having a movable core that acts through mechanical linkage to retract a pair of opposing brakes from engagement against the side walls of the track, thereby allowing the lamp assembly to be moved along the track easily. When the solenoid is de-energized, a compression spring urges the brakes firmly against the side walls of the track, locking the light assembly in place along the track.

Abstract: A locking hinge mechanism for concrete forms includes parallel hinge strips connected together by hinges positioned at intervals along the length of the strips. Each hinge includes provision for a wedge lock which, when fully inserted, positions the hinge strips at a secure 90.degree. angle. The hinge strips are spaced apart from the juncture of the strips, when arranged at the 90.degree. angle, so that concrete flashings do not clog the hinge. The hinge strips are in turn affixed to the side rails of the joining concrete forms to form a 90.degree. angle, such as for a column form arrangement.

Abstract: A method of preserving agricultural products or materials such as hay and silage is disclosed. The method comprises the utilization of a composition for coating the material in order to form a water-repellent protective coating thereon. Preferably the coating includes a preserving agent, having substantial antimicrobial activity. Further, in some instances the coating may include an adhesive forming constituent enabling outer layers of material to become tightly bound in the stack, bale or pile of material being treated. When the latter adhesive compositions are utilized, the treated material tends to retain its physical integrity, against loose portions becoming detached therefrom. Also disclosed are preferred compositions for achieving the methods of treatment, and also preferred methods for preparing certain of the preferred compositions.

Abstract: A registration system for flexible printing plates includes a registration table which, when used in conjunction with a drill apparatus, makes registration and mounting of flexible printing plates on plate cylinders relatively quick and easy. The registration table includes a positioning apparatus against which a plate cylinder is situated. The positioning apparatus is aligned perpendicularly to a table track on which is slideably mounted a plate mounting platform to which the flexible plate is pinned. The plate mounting platform is swept along the track toward the plate cylinder and the flexible plate rolled onto the cylinder, and adhered by double sided sticky tape. The pins affixing the plate to the mounting platform are removed and the remaining plate material rolled onto the cylinder. The process ensures that a selected longitudinal axis of the plate will be in registration, or aligned, with the longitudinal axis of the cylinder.

Abstract: Mops and process for making closed or uncut end mops particularly using single ply cotton yarn having a high degree of twist. The yarn is processed through a fringe making machine into lengths of pre-sewn fringe or processed through a wet mop making machine and the high twist yarn tends to bunch together in thick, ropy masses of yarn strands. The fringe is either affixed to mop backs or affixed together in the middle to form a mop, and the mops are then soaked in a high temperature water bath until the ropy yarn strands relax, straighten and separate. The mops are rinsed and transferred to a high temperature hot air dryer and dried until the separate yarn strands twist about their looped ends to form separate, individual doubled ply yarn strands with uncut ends.
