Inventor: YOUNG WALTER W
IPC: H01B7/02
Filed: 1993-10-08
Abstract: A vibration resistant overhead electrical cable is provided, such as a high-voltage transmission line, which comprises an insulated conductor, the insulation of which has an axially continuously rotating oval or elliptical outer periphery such that the aerodynamic forces acting on the cable act in a continuously changing direction, thereby reducing the tendency of the cable to vibrate. The ratio of the major to minor axis of the oval or elliptical shape is preferably between 1.1 and 1.2 and the length between axial rotations along the longitudinal axis of the cable is usually between  about 2.5 and 3.5 meters.

Inventor: YAPP RONALD A
IPC: A61B17/58
Filed: 1993-11-24
Abstract: An osteosynthesis plate system is particularly well adapted to securely fuse adjacent cervical vertebrae. The plates are adapted for mounting upon the anterior or posterior surfaces of the vertebrae. Plates for mounting on the anterior vertebral surfaces have a concave bone contacting surface and a bone screw locking mechanism integral with each screw hole. Moreover, the bone contacting surface of the plate has a plurality of bone penetrating protrusions to more securely affix the plate to bone. Plates for mounting on the posterior vertebral surfaces also have bone penetrating protections on their bone contacting surfaces. Such plates are formed so as to have a curved bone contacting surface that fs concave in the transverse azis of the plate and convex in the longitudinal axis of the plate. The screw holes of such plates are constructed so as to guide a bone screw along a desired angle to improve the anchoring of the screws in bone.

Title: Method and system for producing mesh representations of objects
Inventor: MESHKAT SIAVASH N
IPC: G06T15/00
Filed: 1993-11-26
Abstract: Abstract A method is provided for producing a mesh representation of an arbitrarily shaped object,  for applications such as finite element analysis. The method includes the steps of identifying elements of a mesh, such as a tetrahedral mesh, which are suitable,  based on predetermined criteria,  for merging into one of a predetermined set of target elements. For instance,  if the predetermined set of target elements includes pentahedra and hexahedra, and the method operates on a tetrahedral mesh, then tetrahedra of the mesh are identified based on known ways of decomposing the target elements into tetrahedra.  In  a  preferred  embodiment,  the  groups  of tetrahedra are identified based on whether they share faces in common, and whether they have faces which share a common edge and which are either coplanar or have an angle between the faces which satisfies a predetermined condition. The latter faces  are  referred  to  as  quadrilateral  pairs.  A  graph representation of the mesh is used, preferably including nodes representing regions of the mesh (i.e., tetrahedra) and edges between the nodes representing faces shared in common and quadrilateral  pairs  of  faces.   Using  a  search  tree representation of a graph of a target element, the graph of the mesh is searched to identify subsets of the graph of the mesh, which represent groups of the tetrahedra of the mesh which are suitable for merging into the target element. By merging the tetrahedra this way, the total number of elements of the mesh is reduced, compared with the original tetrahedral mesh.

Title: Rope grab device indicating the exsistence of shock impact on personal safety
Inventor: BELL MICHAEL
IPC: A62B1/14
Filed: 1994-01-21
Abstract: ROPE GRAB DEVICE INDICATING THE EXISTENCE    OF SHOCK IMPACT ON PERSONAL SAFETY                   ABSTRACT OF THE DISCLOSURE A rope grab for protecting a worker at an elevated position from a fall.  The rope grab is disposed on a vertically extending safety line and is connected to the worker by a lanyard.  The rope grab includes housing having a pivotable actuator mounted thereon.   The actuator includes an serrated extension for engaging the safety line.  A rupturable capsule containing an indicating liquid is located in the housing.  The actuator is connected to the lanyard to secure the worker to the rope grab and is pivotable upon a downward pull thereon to move the  serrated  extension  from  a  first position  to  a  second position.  When the serrated extension is in the first position it engages the safety line slightly to permit the rope grab to be slid therealong.  When it is in the second position it tightly engages the safety line to preclude the device from being slid along said safety line, and causes the automatic rupturing of the chamber, whereupon the indicator liquid flows onto a portion of the rope grab and a portion of the safety line.  The actuator is also arranged to be moved to a third intermediate position wherein the rope grab is precluded from sliding along the safety line but the capsule is not ruptured.

Title: Fence system
Inventor: VISE LARRY L
IPC: E04H17/06
Filed: 1994-03-01
Abstract: A fence system including a frame and a plurality of foraminous panels attached to the frame. The foraminous panels are constructed with continuous integral strands which are connected by integral bonds extending between each of the strands. The integral strands form a zig-zag pattern defining cell apertures therebetween. The cell apertures define a non-circular interior surface. A fastener of the fence system has a shank and a head attached to one end of the shank. A shoulder positioned between the shank and the head is shaped to cooperatively engage a cell aperture for preventing rotation of the fastener when engaged with a foraminous panel. The foraminous panels are attached to the frame with a portion of each neighboring panel having an overlapping area through which fasteners are inserted and attached. An angled top edge cap is attached along a top end of the foraminous panels and is angled to deter climbing. The top cap material is formed of foraminous panels having cell apertures generally smaller than lower panels. The top cap panel material is self-supporting but is incapable of supporting the weight of a climber.      Additionally, barbed segments are formed along a terminal edge of the top cap by shearing one of the integral strands to provide extremely sharp pointed tips.

Title: Recovery of organic acid salts from impure process streams by addition of bases
Inventor: FELMAN STEVEN W
IPC: A23L27/00
Filed: 1994-06-21
Abstract: ABSTRACT This invention provides an improved method for recovering an organic acid as a salt from various process streams by addition of a crystallizing base to a concentrated solution of neutralized organic acid. The addition of such a base causes crystallization of the salt. This process provides more efficient recovery of organic acid salt from a fermentation process stream than traditional crystallization and it may be used essentially as a one step purification process. The improved method is particularly applicable to the recovery of trisodium or tripotassium citrate from process streams produced in the fermentation and recovery of citric acid, with the addition of a crystallizing base such as sodium hydroxide, sodium carbonate, potassium hydroxide, or ammonia. The resulting product may be combined with an anticaking agent and/or dried to provide a particularly free flowing product.

Title: Substituted dipyrromethanes and their preparation
Inventor: WIJESEKERA TILAK
IPC: C07B61/00
Filed: 1994-10-25
Abstract: ABSTRACT OF THE INVENTION     New chemical compounds, bis(pyrrol-2-yl)halocarbylmethanes, also known as meso-halocarbyl dipyrromethanes, are made by recting pyrrole in either of two reaction schemes.  Once such scheme converts pyrrole through an intermediate, a halocarbyl carbonyl pyrrole, to a [2-(1-hydroxyl-1-hydro-1-halocarbyl)pyrrole], and then converts the latter to the desired halocarbyldipyrromethane; the last step in this scheme is a novel and useful method in itself.  The other such sequence converts pyrrole, by reaction with a halocarbyl aldehyde, directly to the desired halocarbyl dipyrromethane.
