Abstract: A therapeutic walker comprises a floor plate with a center board extending upwardly therefrom to maintain lateral spacing between a child's feet as he walks along the board. The ends of the center board are supported by end plates bearing stanchions which receive the legs of a rail assembly. The rails can be adjusted vertically and horizontally for various sized patients.

Abstract: A forceps for holding and everting vessels in an anastomosis procedure includes three cooperating jaws mounted at the ends of respective relatively movable legs. The legs can be independently manipulated in order to secure and evert first one vessel, then another in apposition to the first, so that clips or sutures can be applied to complete the anastomosis.

Abstract: A container for mounted slides comprises a continuous strip of transparent material folded upon itself, with regularly spaced pairs of continuous welds extending across the width of the strip to define a series of transverse pockets closed at one end and open at the other. A number of mounted photographic slides can automatically inserted into the open end of each pocket.

Abstract: A device for automatically inserting packs of photographic negatives and prints into respective pockets of a series of envelopes includes separate guides for supporting and guiding the negatives and prints toward the envelopes, which are supported by a conveyor having intermittent forward and retrograde movement. The device includes a pair of blades which engage the pockets when the envelopes are moved rearward, and then are raised to open the pocket, to permit the automatic insertion.

Abstract: A surgical clip is disclosed having a pair of spaced arms joined by a bridge that is deformed by pulling on a tang, which is connected to the bridge by a frangible neck. Also disclosed is a tool for pulling the tang, and an anastomosis procedure that may be quickly performed using the clip and tool.

Abstract: In improved equipment for lapping internal surfaces, use is made of a composite lap, the rod of which is held by the tool spindle and inserted with a marginal degree of clearance into a cone that carries the abrasive shell, and a chucking mechanism located beneath and coaxial with the spindle and lap; errors are avoided, particularly with smallbore work, by embodying the lap rod in three rigidly associated sections, namely, a polygonal tip, insertable and fastened with a transverse pin in a matching polygonal socket offered by the cone, a flexible coupling section, and a shank uppermost that is screwed into or otherwise clamped to the spindle. Work to be lapped is held in a chuck suspended from at least three cables threaded through relative peripheral mountings afforded by the chuck itself.

Abstract: A sectionalized screen/basket assembly for a centrifugal dryer for coal slurry comprises a screen formed in an upper section and a lower section, enabling one to save substantially on screen replacement costs, inasmuch as the great preponderance of screen wear in such dryers is at the top of the screen, at the point of slurry introduction. An internal circumferential ridge on the upper screen creates a particle cake that further reduces wear.

Abstract: A flexible, thermally insulated conduit has a central pipe and a coaxial casing spaced therefrom by annular spacers, defining a series of seated chambers. The chambers are filled with a foam material.

Abstract: A working head for a tree-shaping machine comprises drive means and at least one shaping unit comprising at least one mobile blade and an actuating jack (8, 9) for applying the blade to the surface of a tree. The pressure in the jacks is cancelled during the starting phase of the drive means.

Abstract: The storage cabinet comprises a frame supporting at least two superimposed rows of pivoting storage modules.The closing-opening angle of rotation .beta. of the storage modules is calculated according to the center distance y of the axes of rotation of the modules and of the distance x between the plane defined by the rear upper edges of the storage modules and the plane defined by the front lower edges of the storage modules according to the equation sin .beta.=x/y.The difference between the levels of the lower edge of the front wall of an upper adjacent module and of the upper edge of the rear wall of a lower module is calculated according to the equation z=y (1-cos .beta.).The upper edge of the rear wall of a lower storage module comes in the simultaneous opening movement to stop on the lower edge of the front wall of the adjacent upper storage module so as to precisely stop rotation of the storage modules.

Abstract: A mechanical tubing cutter for severing and retrieving fish from wells comprises a slip body for clamping the upper end of the fish, and cam-actuated cutter knives for severing the fish below the slip body. The clamping and cutting operations occur in an automatic and predictable sequence as upward force is progressively applied to the tool. The tool may be used as a releasing overshot merely by substituting a slip body setting sleeve for the cutter knives.

Abstract: An assembly for attaching a brake cam shaft to a slack adjuster includes a cam shaft with cam elements at one end thereof and an attachment portion at its other end. The shaft has a spline adjacent the attachment portion. A securing member is locatable about the shaft or a shoulder on the shaft, the securing member or shoulder limiting the extent to which the splined end of the shaft may project into or through the splined aperture of the slack adjuster. A fastener is secured to the attachment portion such that when the shaft is securfed to the slack adjuster, the shaft is held fast relative thereto with the slack adjuster located between the shoulder or the securing member and the fastener.

Abstract: The device comprises, among other things, a hand piece (10) equipped with a support (12) movable in translation for a needle (51). Support (12) is moved by a catapult which comprises a propelling device (133) made of a pneumatic microactuator with a simple spring-back effect.Application to human mesotherapy, for example, FIG. 3.

Abstract: Both the wet strength and the folding endurance of kraft linerboard are improved by subjecting the board to steps of densification and high temperature treatment during its production.
