Abstract: A sealing arrangement for trocar tubes including an upper ring seal forming the primary seal, and a lower seal valve forming the secondary seal. Both seals form part of a valve system which can be positioned within a removable cartridge. The valve cartridge comprises a tubular open-ended housing in which the seal ring is fitted to the top opening, and with the seal valve located within the housing. The seal valve is elastomeric in tubular form for passing instruments and is provided with upper and lower flanges for placement within the cartridge. The intermediate portion of the valve between the flanges is in the general form of converging and diverging frusto-conical sections which join along a sealing line. A seal is formed between the interior wall surfaces of the valve and the instrument present in the trocar tube. Peritoneal pressure is admitted to the trocar head or housing for pressing the valve in forming the desired seal.

Abstract: An arrangement for insulating junctions of three or more conductors utilizing standard connectors for joining conductors having different types of insulation and/or different sizes. The junction is enclosed in a cage formed of wire, wire and sheet metal, sheet plastic, or molded plastic. The cage material is supplied in sheet form and is cut to appropriate size for a particular junction to form an armature for supporting insulating material. A hoop may be used to support the cage. Insulation covers the cage and connectors.

Abstract: A tube cleaning apparatus for tubes and pipes installed in power plant and similar industrial equipment utilizes a rotating brush assembly fitted to one end of a rotary cable encased in a protective casing and driven at its other end in clockwise and counterclockwise rotation by a reversible motor. The invention provides a drive unit fitted with a plurality of drive rollers for engaging the protective casing and propelling the casing, cable and brush assembly at a high rate of speed into and out of each tube being cleaned. A control system for the drive unit enables the operator to manipulate the reversible motor by issuing pulses to actuate switches controlling on/off and direction of rotation of the motor. An arresting device provides for stopping forward progress of the brush assembly as it reaches the end of each tube being cleaned.

Abstract: An improved prosthesis cover of waterproof material which closely conforms to the shape of the limb being covered, has an antifriction inner surface and an antiskid sole in the case of a leg cover.

Abstract: A disposable pocket for temporary attachment to a person's outer garment and for receiving and holding an animal treat. The pocket is constructed such that there are front and back panels joined to each other along a leakproof seam to form a pocket and wherein a top panel is attached along its front and back edges to the upper margins of the front and back panels. The pocket is constructed of greaseproof material and there is a slot in the top panel. The rear panel has a pressure sensitive adhesive thereon to attach the pocket to a garment as desired. The front panel may be textured to give the appearance of fabric.

Abstract: A hand held gauge for accurately measuring the circumference of conductors especially conductor cables with multiple strands, for indicating correct connector size for the conductor, and for aiding in the assembly of a bare conductor end into a connector sleeve.

Abstract: Limiters for protection against fault currents in electrical distribution networks the limiter having externally visible indicator for indicating that a limiter element has fused and which visible indicator may be reset and reused after a fused limiter is replaced.

Abstract: A method and apparatus for cleaning ducts such as used in HVAC systems includes as part of the apparatus a propeller having pitched, flexible blades for rotatably engaging the interior duct surface for dislodging soot and propelling a cloud of soot along the duct to an evacuation point. The method includes establishing a temporary block in the duct, moving the propeller along the duct for dislodging soot and generation a dust cloud, and evacuating the duct by drawing the soot cloud created by the propeller.

Abstract: Crimping dies for hydraulic compression tools for electrical connectors and the like in which one of the dies in a matching set is provided with means for engaging and stopping a connector workpiece in proper position for crimping in the die jaw.

Abstract: The terminal effectiveness of fin stabilized, subcaliber armor piercing projectiles depends primarily on the impact velocity at the target. The aerodynamic drag and related velocity decay experienced over the trajectory from the gun to target is reduced by shortening the length of the acceleration transfer interface between subcaliber projectile and discarding sabot. This applies for multiple annular grooves and helical grooves. Special groove configurations to reduce the pressure drag and related boundary layer shock wave interaction are disclosed. The reduction in length of the acceleration transmitting interface permits its location to a position aft of the point of boundary layer transition from laminar to turbulent flow and therewith to take advantage of the low frictional coefficient of the laminar boundary layer over a large portion of the subcaliber projectile. The resulting reduction in aerodynamic drag is particularly effective for mid caliber projectiles.

Abstract: A blood coagulation test system for in vitro assessment of blood characteristics including hemostasis, thrombus formation, thrombolysis, and collagen platelet interaction includes a syringe/test cartridge for collection, testing and disposal of the sample together with a test analyser for executing the test protocol. Coagulation functions are evaluated by establishing controlled bleeding of the sample from a capillary tube within the cartridge and monitoring these blood characteristics as a function of blood pressure variations occurring in the cartridge as the test proceeds. The blood sample remains within the cartridge for testing and after disposal.
