Abstract: Apparatus for connecting the ends of a suture stitch includes a piston and cylinder combination with one end of the suture secured to the cylinder. The other end of the suture initially includes a needle for penetrating two tissues to be approximated and then passing the needle and its attached suture through aligned openings in the cylinder sidewalls. The portion of the suture passing through the cylinder is trapped therein by the depression of the piston to engage the bottom inside surface of the cylinder which locks that end of the suture in place.
Abstract: An accelerometer is attached to a pipe wall to measure the acoustic pressure waves generated in a fluid within the pipe as a result of a leak in a valve in the pipeline. Calibrating the accelerometer and tuning it to particular wave frequencies allows a determination of the magnitude of the leak through the valve.
Abstract: A bristle strip for rotary brushes comprising a supporting channel in which the closed ends of the U-shaped bristles are clamped. The channel is provided with laterally-extending guide members mounted directly thereon that project laterally outwardly beyond its side flanges to guide the strip when it is inserted in a guide track on a rotary drum and to retain it therein. Due to the simple nature of the strip it can be produced at a low cost without special tooling.

Abstract: A mechanical stage having stacked parallel plates which are movable orthogonally is used to locate a specimen mounted on one plate at a desired location for observation through a microscope, photography or the like.
Abstract: Patching grout is forced into a break in the sidewall of a chimney by having the repairing person deposit a quantity of grout on the upper side of a trowel and move the trowel into a position immediately below the break. The trowel is pivot-ably mounted on the end of a linear handle and the trowel is raised into position on the handle. The upper side of the trowel is tilted toward the break by a cord extending from the trowel to the worker simultaneously with the worker pushing the handle upward to thereby mash the grout against the sidewall. Thereby the grout is pushed into the break as the trowel slides upward scraping against the sidewall.
Abstract: Seat covers are sewn inside-out and then inverted to fit over a frame. Inversion is accomplished by threading the sewn seat cover over a pair of generally parallel arms. The sewn seat cover is generally in the form of a pocket. The closed end of the pocket is engaged by the blunt edge of a plate. The plate pushes the closed end between the arms forcing the structure of the pocket to ride up and over the top of the arms and downward between the two arms thereby inverting the seat cover to a right side out condition.

Abstract: The present invention is an improved method of making sequenced chemical chain compounds through the application of laser copy technology to UV light directed spatially addressed parallel chemical synthesis and is particularly useful in the production of numerous proteins of varying amino acid sequences on a restricted solid support. Chemical groups, such as amines, are attached to the surface of a solid sup- port, such as flat glass, and subjected to chemical reaction disposed to link chemical units to the attached groups that are protected from further reaction by photolabile groups. Such solid support and photolabile protected units are then selectively deprotected by irradiation with a UV laser beam. The support and attached units are then subjected to chemical reaction to link chemical units to the selectively deprotected units. By repeated such treatment it is possible to produce unlimited combinations of chain chemical units in less time and at greater efficiency than has previously been possible.
Abstract: An insert for mounting in the corner of a door or window frame opening includes two mounting flanges bonded along two edges of a glass panel. The flanges define an L-shape. Mounting within the frame is by fasteners which extend through apertures through the flanges.
Abstract: A focusing mechanism for telescopes, microscopes and the like uses a tensioned strap circumscribing a pair of wheels in a generally S-shape whereby rotation of the wheels moves the eye piece of the scope to proper focus location.

Abstract: A bow press includes pivotable arms on a linear frame. The bow fits on the press between two pegs projecting from the frame and a pair of prongs, one prong projecting from each arm. Simultaneous pivoting of the arms bends the limbs of the bow. Proper adjustment of the pegs and prongs prevents movement of the limb surface with respect to the pegs and prongs.
Abstract: A battery powers the motor of an electrically powered impact gun. The body of the gun vibrates at some frequency and an aluminum brush holder therein is configured to vibrate at about the same frequency to minimize chatter and arcing of the brushes on the commutator bars.
Abstract: A nested fiber gas burner is formed with a burner body having an inlet on one end and a burner port on the other end. A mat of fibers is formed from discrete fibers of material randomly deposited into a mold having the general configuration of the burner port. After the fibers are deposited in the mold to a depth of about 0.5 inch, they are heated to a temperature of about 1200.degree. C. for about two hours, which causes the fibers to bond together. Thus bonded, the fiber mat is secured in place in the burner port.
