Abstract:
Various embodiments of the present invention comprise apparatus, assemblies and methods for towing a vehicle using a swivel head assembly. The swivel head assembly can permit a grid head of a towing system to roll as well as yaw with respect to a tow arm. Spring members are also provided that can help dampen roll motions.
Abstract:
Described are embodiments directed to an apparatus that is adapted to be mounted on a vehicle with a fifth wheel. The apparatus allows a towing hitch to be attached to the vehicle which allows the vehicle to tow other vehicles. The apparatus includes an elongated beam with a forward portion, middle portion, and rearward portion and a kingpin connected to the middle portion of the beam and adapted to engage a fifth wheel. A mounting pin with a first end and a second end is connected to the rearward portion of the beam and is substantially perpendicular to the elongated beam. The apparatus further includes strut braces connected to either end of the mounting pin and that extend at an angle away from the mounting pin. The strut braces are also connected to leveling assemblies which are adapted to connect to a frame of the vehicle and are adapted to change the vertical position of the rearward portion of the beam.
Abstract:
A stable, sterile aqueous solution of a compound of formula (I): in which A is a C alkylene group with a chain length between NH and N(O)R′R″ of at least 2 carbon atoms and R′ and R″ are each separately selected from C1-4 alkyl groups and C2-4 hydroxyalkyl and C2-4 dihydroxyalkyl groups, or R′ and R″ together are a C2-6 alkylene group, is formulated in a unit dosage form in a sealed container, said solution having a concentration of the compound of formula (I) up to 150 mg/ml and a pH in the range of 5 to 9. The solution may be prepared without a freeze drying step.

Abstract:
A disposable, in-line heating cassette and apparatus for raising the temperature of fluids. The cassette comprises a spacer defining a sinuous or serpentine flow pathway interposed between flexible foils and mounted on a frame. The frame comprises inlet and outlet tubes and related input and output ports which communicate with the serpentine path. Juxtaposed heating plates in direct contact with the cassette substantially contact the entire heating surface of the foils, providing a highly efficient thermal path from the heating plate to the foil, and then to the fluid. The heating blocks have several electrically conductive strips thereon for generating a gradation of heat energy such that more heat energy is available for transfer at the inlet end than the outlet end of the serpentine flow path. The strips are arranged on the heating plates immediately over and under the serpentine flow path and are divided into contiguous perpendicular sections, each section having a corresponding closest parallel section with a conductor separation distance therebetween.
Abstract:
A prosthetic tricuspid remodeling annuloplasty ring for use in tricuspid valve repairs to provide annular support after reconstructive valve surgery. The ring maintains an optimal annular dimension to prevent excessive dilatation of the natural valve annulus while adapting to the dynamic motion of the tricuspid annulus during the cardiac cycle. An exemplary ring features a waveform contour and may be constructed of a titanium core having a varying cross-section for selective flexibility for good Z-axis or out-of plane movement. The “waveform” contour and selective flexibility of the different segments of this ring are designed to adapt to the complex motion of the annulus. This reduces the stress on the anatomical structures and therefore minimizes the risk of arrhythmia and ring dehiscence.

Abstract:
A fluid gas removal drip chamber for use for parenteral administration of fluids is disclosed. The drip chamber has a hydrophobic barrier which extends into the interior of the drip chamber. The hydrophobic barrier preferably comprises at least a portion of a three-dimensional surface. In one embodiment, an inlet port allows fluid to enter the drip chamber from the top so that the fluid falls through an air space formed in the top of the drip chamber. By shaping the inlet port so that droplets of fluid are formed, a health care professional can monitor the fluid drip rate. In another embodiment, the hydrophobic barrier is configured so that little or no air space exists at the top of the drip chamber. The drip chamber includes means for venting air that is separated from the fluid within the chamber and, at the same time, preventing air from entering the chamber through the venting means. For certain applications, the drip chamber is provided with a hydrophilic filter for filtering the fluid prior to exiting the drip chamber.
Abstract:
A method and apparatus for managing load in a communication network are provided. At a processor of a relay device, a number of messages is determined that are one or more of currently queued for relay via a communication interface of the relay device and previously relayed within a given time period, the communication interface and the processor of the relay device for relaying the messages, via the communication interface, between a plurality of devices and a network infrastructure. At the processor, a rate at which the plurality of devices establishes communications with the network infrastructure is controlled, wherein there is an inverse relationship between the rate and the number of messages.
