Abstract: ABSTRACT         A package for multiple strands of surgical sutures which provides for delivery of individual suture strands.  The several sutures are contained within a single compartment of the package, with each suture being individually wound in the form of a coil comprising a series of convolutions, each convolution being laterally displaced from adjacent convolutions and disposed in sequence over the length of the suture.  Each individual suture within the package compartment is laterally displaced from adja-cent sutures in a contiguous, partially overlapping relationship.            The desired suture coil configuration and positioning within the package compartment is conveniently obtained by sequentially winding individual sutures around two vertical winding pins in an upwardly spiraling pattern, with successive loops of each su-ture and successive sutures being displaced laterally along the pins.  The wound sutures are packaged in a suture folder which is adapted to maintain the individual sutures in their wound con-figuration and in their relative positions with one end of each suture extending from the folder whereby individual suture strands may be grasped and withdrawn from the package without en-tangling sutures remaining in the package.

Abstract: Application of John V. Levy, David P. Rodgers, Robert E. Stewart and Richard J. Casabona Relating to DATA PROCESSING SYSTEM WITH READ       OPERATION SPLITTING     Abstract of the Disclosure.           A digital data processing system including an interconnection for the various elements that constitute the system. Each element that connects to the interconnection is called a nexus. For one element to communicate with another element, the one element, as a commanding nexus, seeks control of the interconnection and then transmits a command and address of a storage location in the other element when it receives control of the interconnection. Control is then relinquished unless the one element is to send data to the other element whereupon the data is sent immediately. If data is to be retrieved, the other element retrieves the data, requests control of the interconnection and, when it receives control, transmits the data onto the interconnection with an identification of the one element. The one element then retrieves the data from the interconnection when it recognizes it s own identification. If the other element is a memory element, it also contains storage file foe storing commands and data if it already is operating in response to another element's command.

Abstract: Abstract of the Disclosure A U-shaped heater unit is surrounded by a U-shaped bimetal, the legs of which move in response to temperature variations.  The motion of the bimet-al is conveyed through a wall by  a slidable pin which acts to rotate an L-shaped compensator element.  This rotation lifts a link element which operates a switch when the trip point is reached.  A reset mechanism includes a plunger which when manually depressed rotates a reset arm first in one direction to reset the switch after it has been tripped and then in the opposite direction to a neutral station in which it will not reset the switch.  The reset mechanism thus cannot be defeated by jamming the plunger in its fully depressed position.

Abstract: COKE QUENCHING PRACTICE FOR ONE-SPOT CARS       Abstract of the Disclosure A process for quenching hot coke discharged from an over of a battery of coke ovens into a one-spot car.  The process utilizes a unique arrangement of two sets of narrow angle spray nozzles to quench the coke.  In addition to quenching the coke, one set of spray nozzles initially knocks down the peak portion of the coke pile and distributes the coke so that the exposed surface of the coke is sub-stantially level.  The quench liquid discharged through the narrow angle spray nozzles contacts about 50% to about 70% of the substantially level, exposed surface of the hot coke. Sufficient openings are provided adjacent the bottom of the one-spot car to drain the quench liquid to prevent the buildup of quench liquid in the quench car.

Granted: 1982-04-27
Abstract: ABSTRACT OF THE DISCLOSURE         There is provided an assembly for opening and closing a closure lid of a grain bin or silo from a remote position, such as ground level.  The assembly comprises a lever member having pivotally interconnected lower and upper levers with the lower end of the lower lever being pivotally mounted about a fixed pivot axis and the upper end of the upper lever being pivotally connected to one end of an operating arm the other end of which is pivotally connected to the upper end of a latch arm, a spring acting between the lower and upper levers resiliently to urge these levers towards a limit condition in which abutment portions of the levers are in contact to limit relative pivotal movement between the levers in a direction in which the upper lever pivots relative to the lower lever away from the operating arm.          Intermediate its ends the latch arm is pivotally connected to the closure lid at a position diametrically opposite a fixed pivot axis about which the closure lid can be pivotally raised and lowered between a closed position and an open position, and the lower end of the latch arm presents a latch member which is engagable with a fixed bracket member when the closure lid is in the closed position thereof.  A relatively stiff but resiliently deformable strip is adjustably connected between the closure lid adjacent the fixed pivot axis thereof and the operating arm adjacent the pivotal connection thereof with the upper end of the upper lever.  When a flexible cord or cable connected to the upper end of the lower lever is operatively pulled there is relative pivotal movement between the levers against the influence of the spring with the latch member being initially moved out of engagement with the fixed bracket member with resilient deformation of the resiliently deformable strip, and thereafter the closure lid is pivotally raised about the fixed pivot axis thereof.  Releasing of the cord or cable results in the closure lid being urged under the influence of the spring pivotally to be lowered to its closed condition.
