Title: Closable container for receiving and disposing of  surgical sharps
Inventor: ALIKHAN RAZA
IPC: A61B50/33

Abstract: CLOSABLE CONTAINER FOR RECEIVING AND DISPOSING OF SURGICAL SHARPS            ABSTRACT OF THE DISCLOSURE        A  closable  container  is provided  for  receiving  and disposing  of surgical sharps following their use in any surgical procedure.  Surgical sharps include suture needles, blades, pins, and hypodermic needles,  all of which may easily cut or  puncture tissue, and all of which may become contaminated after use due to contact with contaminated tissue.   The container is formed using a continuous vacuum-forming process,  generally on form, fill and seal  packaging  machines  that may be  somewhat  modified, from continuous  rolls of sheet thermoplastic material,  so  that  the container  comprises  pair of trays with a living  hinge  between them.  An  upstanding lip around one of the trays is accommodated in  the  other tray when the container  is  closed.   A  magnetic material  is adhered to the outside flat surface of at least  one of  the trays so as not to come into contact with the instruments that   may  touch the tray,  such as needle holders  used  during suturing.   A foam layer may be placed in one of the  trays;  and both  of  the  trays and foam when installed may or  may  not  be marked  with indicia for easy counting depending on the surgeon's or nurses individual preference.  A suture organizer comprising a convoluted  layered  structure,   may  also  be  provided.    The container  may  then be reprocessed through the same  machine  to seal it inside a package so that it can be provided in a  sterile condition  for opening in the operating theater.  The  container, though deformable,  is sufficiently semi-rigid and tough so as to prevent  sharps from piercing through the container walls to  the outside;  and  together with its lip and hinge,  provides a  safe receptacle for the disposal of surgical sharps.

Abstract: FAULT RESPONSIVE MEANS FOR CHANGING CONTROL SEQUENCE     OF A MULTIPLE-BRIDGE ELECTRIC POWER CONVERTER          ABSTRACT OF THE DISCLOSURE In the propulsion system of an electric locomotive, a-c wayside power is converted to direct current for the traction motors by means of several phase-controlled rectifying bridges having serially connected outputs The bridges are controlled sequentially so that their respective output voltages are introduced in stages as increasing amounts of voltage are required at the motors of an accelerating locomotive.  Normally certain thresholds of speed need to be attained before the second bridge, and later the third bridge, are permitted to be phased on.  Means is provided for changing the bridge control sequence in response to faults in the first or second bridges.

Abstract: ABSTRACT            ALUMINUM-RESISTANT TITANIUM DIBORIDE ARTICLES              AND METHOD OF MAKING SAME          High strength titanium diboride (TiB2) articles which are obtained by sintering articles preformed from TiB2 powder mixed with epoxy resin by means of isostatic molding using sintering temperatures found to be a critical variable for achieving maximum strength.  Resistance to aluminum attack is achieved by removing contaminating oxides, nitrides, and carbides of titanium by selecting either annealing the sintered article in a boron nitride (BN) pack or by including a small amount of BN or elemental boron in the original TiB2 powder, such that the finished article is substantially free of such contaminants.

Abstract: METHOD AND APPARATUS FOR MAKING ALLOY POWDER              ABSTRACT OF THE DISCLOSURE          An improved method for making a metal powder employs improved apparatus comprising, in combination, a fluid-cooled hearth for receiving metallic material which defines an alloy and which is to be melted, a plasma heat source adapted to melt the metallic material, a powder metal producer, and means to introduce the molten metallic material from the hearth into the powder metal producer.          The fluid-cooled walls of the hearth resolidify a portion of the molten metallic material to form a skull as a barrier between the hearth and additional molten alloy produced within the hearth.  This method and apparatus restricts introduction of impurities into the molten alloy which is later introduced into the powder metal producer.  In one form, a fluid-cooled pouring trough, as a stream control device, can be disposed between the hearth and the powder producer to receive molten metal from the hearth and to introduce it into the powder metal producer.

Abstract: SYNCHRONIZATION OF REAL-TIME CLOCKS    IN A PACKET SWITCHING SYSTEM            Abstract A packet switching system in which a remote real-time clock is accurately synchronized to a standard real-time clock via X.25 (CCITT) controlled high-speed transmission links.  Synchronization is achieved by the transmission of an interrupt packet and a data packet between a remote processor controlling the remote real-time clock and an administrative processor controlling the standard real-time clock.  Synchronization involves the following steps:  (1) assembling an interrupt packet comprising the least significant bits of the remote real-time clock for transmission to the administrative processor by the remote processor, (2) calculating bits representing the difference between the transmitted least significant bits of the standard real-time clock by the administrative processor, (3) assembling a data packet comprising bits representing the state of the standard real-time clock and the difference bits for transmission to the remote processor by the administrative processor, (4) adding the difference bits to the bits representing the state of the remote real-time clock by the remote processor, and (5) adding a predefined value to the most significant bits of the remote real-time clock by the remote processor if the transmitted least significant bits of the standard real-time clock are numerically greater than the least siginificant bits of the remote real-time clock.

Abstract: GEL AND PROCESS FOR PREVENTING CARBON DIOXIDE BREAK THROUGH                     ABSTRACT A gel-forming composition is provided comprising a first substance selected from the group consisting of a polyvinyl alcohol, a polyvinyl alcohol copolymer, and mixtures thereof, an aldehyde, and water, and which requires contacting with a brine which has absorbed substantial amounts of carbon eioxide before the gel-forming composition will form a gel.  The gel-forming composition is useful for retarding the flow of carbon dioxide and other fluids in subterranean formations.  For example, a method is provided for preventing the loss of carbon dioxide to nonproductive parts of an oil reservoir.  Such method is particularly useful in carbon dioxide flood operations to increase the sweep efficiency of the oil recovery process and in cyclic carbon dioxide injection operations for increasing the fluidity of the reservoir oil.

The  stations are allocated use of  the communication medium during one or more priority intervals as a function of the priority of the packet which the station is ready  to  transmit.    Each  station              is synchronized to a transmission cycle period which is divided  into  subperiods.   Certain  types  of packets are  relegated to  transmission  and  reception within predetermined subperiods.

Abstract: ABSTRACT          A user-friendly video measuring system employing a TV camera having a two-axis array of photosensors, a memory, a monitor, a keyboard and a joystick.  The camera takes a first picture, which is stored in memory and displyed on the monitor.  In response to a series of menus, an operator uses the joystick to manipulate a cursor on the monitor to locate a series of start search points for the first picture, and to select gradient threshholds for one or more features.  Both the start search points and gradient thresholds are stored.  The operator also selects and stores tolerances for the measurements.  A second picture is taken and examined, commencing with the stored start search points, to determine whether the gradients exceed the stored threshholds.
