Abstract: ABSTRACT           Electrical pulse generator to operate a remote water meter indicator in which the pulse generator is driven by the drive of the meter to cause a magnetic circuit to be opened and closed in accordance with the rotation of the meter drive.  The magnetic circuit is opened and closed in a manner whereby a linear force element, i.e., a spring, is acting against a magnetic gap so that the spring is extended by rotation of the drive until the force in said spring is sufficient to overcome the magnetic force and open the gap to cause a large change in the reluctance of the magnetic circuit, generating a pulse in a coil which can be then used to drive a remote reading meter.

Abstract: ABSTRACT OF THE DISCLOSURE In a composite action open-web steel joist, comprising supporting beams and girders, and reinforced concrete slab interconnection, it is known to have upper apex portions of the steel joist webbing protrude through the upper chord members of the joist and through apertures provided in the sheet metal formwork placed over such joists prior to the pouring of the concrete slab.  In this invention, the improvement relates to a continuous round rod secured near the apex of each projecting web member parallel to the longitudinal axis of the joist and a reinforcing wire mesh draped between said rods, thus permitting greater spacing between said joists, whereby said protruding apex portions, said rods and said draped wire mesh will be encased within the slab to act as shear interconnection and reinforcement devices therein, to secure the joist and formwork together, to enhance the locking of the concrete slab to the protruding joist apex portions, and to the supporting beams through the joist end connection welded to the beam or girder, and to reinforce said concrete slab.  This improvement makes optional the use of wedge members forced between such protruding joist apex portions.

Abstract: ?stract of the Disclosure The embodiment of the invention disclosed is a con-veyor roll having a cylindrical shell with integral end caps and axial sleeves extending inwardly from the end caps.  The shell, end caps and sleeves are rotatably journalled about the shaft by roller bearings between the sleeves and the shaft. An internal labyrinth is provided in each sleeve between the bearing and the end of the shell, this internal labyrinth including a rotatable collar and a non-rotatable bushing carried respectively by the shell and shaft and having a series of facing cylindrical and annular surfaces providing a labyrinthine passage-way of restricted cross-section extending from the bearing means to an annular outlet at the end of the shell.  An external labyrinth is provided outside the end cap.  This includes first and second annular flanges carried respectively by the shaft and shell and axially spaced from the annular outlet and from one another.  These two flanges provide inner and outer radial passages.  The outer radial passage has radial and axial dimension exceeding those of the inner radial passage whereby centrifugal force acting on a radial column of lubricant in the outer radial passage opposes leakage from the shell.

Abstract: ABSTRACT OF THE DISCLOSURE   An optical scanning system for scanning a code pattern comprising several parallel lines provided on an article is disclosed.  The system in-cludes a light source, such as a laser, which directs a beam of light at a polygonal rotating mirror which has several reflecting surfaces.  Several stationary mirrors are located in the path of beam reflection from the rotat-ing mirror to derive several light-beam scanning lines which intersect each other on the surface of conveyor belt carrying articles bearing the code to be scanned.  All of the code bars of each article is completely scanned by at least one of the scanning lines.  The lengths of the scanning lines may be increased by tilting the reflecting surfaces of the rotating mirror with respect to each other.  The invention ensures that the code on each article will be scanned completely in one stroke irrespective of the orientation of the code with respect to the conveyor.

Abstract: TITLE:  SHORT-CRIMP SURGICAL NEEDLE      Inventors:        JOHN RONALD HOFFMAN              PETER JOHN MARSLAND 4 Polaris Drive                  48 Chalk Hill Road New Milford, Conn. 06776         Monroe, Conn. o6468 Fairfield County                 Fairfield County ABSTRACT OF THE INVENTION Surgical needles are attached to sutures with controlled pull-out characteristics by a short crimp--that is a crimp whose length is markedly less than the length of the end of the suture in the needle; with an essen-tially undistorted portion of the needle adjacent to where the suture emerges from the needle, and an essentially undistorted portion around the front of the suture, so that only a short section of the needle is crimped around the suture.  This leaves the suture uncrushed where it emerges from the needle and hence of superior strength where sharp bends occur during use.  It also leaves an undistorted portion of the suture ahead of the crimp so that on pull-out, the suture is retained not only by frictional engagement of the crimp but also by the forces required for the distortion of the head of the suture so that it will pull through the reduced section of the crimp.

Abstract: ABSTRACT OF THE DISCLOSURE               A scraper bar for use with conveyor belting and the like to clean such belting of material adhering to its surface.  The scraper bar consists of a layer of hard abrasion-resistant pellets embedded in an elastomer to form an elastomer/pellet matrix.  An additional layer of elastomer is cast to the matrixed layer to provide a surface for attaching the scraper to its support when in service. Embedded in the layer of unmatrixed elastomer is an insert of particle board, chipboard, plywood or fiberglass reinforced plastic sheeting.  The insert prevents bending of the scraper bar due to differential shrinkage between the layer of matrixed elastomer and pellets and the supporting layer of elastomer.

Abstract: TITLE     APPARATUS AND METHOD FOR INSPECTING GLASS CONTAINERS     ABSTRACT OF THE DISCLOSURE An apparatus and method for inspecting the side wall of a glass container for ribbon tear defects wherein the container is rotated past a detector assembly. TWO pairs of photovoltaic devices mounted in the detector assembly in a vertical line parallel to the vertical axis of the container respond to the light transmitted through the side wall of the container from a light source focused on the interior of the container. Each cell output signal is logarithmically amplified and filtered to remove the d. c. component thereby eliminating differences in magnitudes between the signals not caused by the detection of a seam or a defect. Each cell output signal is then compared with each of four reference signal levels corresponding to severe, normal and small changes in the signal level, the latter level being further divided into light focusing and light scattering changes. The comparison output signals are the inputs to logic circuits for distinguishing among seams, minor defects and ribbon tear defects by determining if the signals satisfy at least two of four conditions. The first condition, which always must be satisfied, is that either one of the pairs of cells has made a detection at at least the normal reference signal level. The other conditions include a second detection within 150° of container rotation from the first detection or a detection of at least a pre-determined width or a detection wherein the two pairs of cells do not detect simultaneously hut may both detect within a predetermined distance of one another. If a ribbon tear defect is detected, the logic circuit will generate a signal to an associated inspection machine to reject the container.
