  • Publication number: 20150371348
    Abstract: A Total Relative Value Platform may be provided. The platform may be used to quantitatively make comparisons between law firms and attorneys working on similar matters in the same or similar jurisdictions. The platform may take a set of data related to a selected legal team's performance on a matter and calculate a score representing the legal team's overall effectiveness in resolving the matter (a “GLI Score”). The performance data may include, for example, information indicating the time spent on various tasks, expenses, cost of resolving the issue, and whether the outcome was positive. In this way, it may be possible to compare the GLI Scores of various legal teams with respect to similar matters and determine which legal team is more likely to have a better future performance. Thus, the platform may allow entities to lower their legal costs and make better decisions in the hiring of outside counsel.

  • Patent number: 5902589
    Abstract: Aqueous solutions of hydratable polymers are prepared by hydrating a hydratable polymer in water without agitation sufficient to shear the molecular structure of the polymer thereby maintaining intact the polymer's molecular structure thereby providing a structurally uniform composition. The resulting solutions are sticky and tacky and are useful in controlling insects and for other uses. The resulting solutions can be dried to form powders. The resulting products readily degrade, are non-toxic, and non-ionic, and hence environmentally benign.

  • Patent number: 5603344
    Abstract: A water saving device for use with domestic hot water systems of the noncirculating storage tank heater type uses a hydraulic motor to drive a water pump to pump water from the hot water pipe to a cold water pipe. Pumping begins when a hot water tap connected to the device is turned on and the water in the hot water pipe is cold. Pumping continues until a temperature sensing element senses that hot water has reached the water saving device and actuates a valve. When hot water is present at the device, the valve permits the hot water to pass directly to the tap instead of driving the hydraulic motor.

  • Patent number: 5409703
    Abstract: A therapeutic medical device is described that is comprised of a dried hydrogel of a hydrophilic-hygroscopic polymer, such as an unmodified or modified polymeric carbohydrate, in the form of a solid foam. The dried hydrogel is prepared by preferably freeze-drying a hydrogel of this polymer in a liquid medium, such as water. The dried hydrogel can be sterilized by radiation or other means so that the sterilized product has a relatively indefinite shelf-life without refrigeration. The resultant dried hydrogel can be transformed into a hydrogel upon absorption of addition liquid medium. The described therapeutic device can serve as a dressing for a wound or lesion, drug delivery system, a hemostatic agent and a biologic response modifier. The described therapeutic device enhances the wound healing rate.

  • Patent number: 4762224
    Abstract: A container for facilitating the manufacture, handling, shipping and storage of products to be produced by the intermixture of a plurality of ingredients, the intermixture of which for various reasons should not be performed until a time just prior to the application of other end usage thereof. The container is provided with internal partitions dividing its interior into a plurality of compartments, in each of which one of the product ingredients is initially stored for shipping and handling. The compartments are sealed from each other to prevent premature intermixture of the ingredients. Opening of the container in a prescribed manner removes the partitions to permit intermixture of the ingredients at the desired time, that is just prior to actual usage.

  • Patent number: 4324262
    Abstract: A catheter adapted to be introduced into a body cavity, such as a bronchial tube or lung, and a method of using the catheter. The catheter consists of inner and outer concentric tubes having a reflected cylindrical membrane attached adjacent their distal ends. Pressurized fluid may be introduced through the perfusate passage running between the tubes and thus between the walls of the reflected membrane in order to provide relative rigidity for the membrane and to seal the reflected end of the membrane, thereby creating a closed pristine chamber, defined by the walls of the reflected membrane about the end of the inner tube. A cage composed of balls mounted on resilient pins may be disposed within the reflected membrane to aid the reflection of the membrane. A portion of the reflected membrane may be perforate.
