Abstract:
A feeding bottle (10) comprises a container (12) having a threaded neck (22) around an opening of the container, a teat (16), and, a threaded annular collar. The teat has a flange (84), adapted to seat on said neck, a nipple (88), remote from the flange, and a one-way valve (110) formed in a depression (112) in the teat to allow the passage of air into the container but prevent leakage of liquid from the container through the valve. The collar is adapted to receive the teat through the aperture (56) of the collar. The depression (112) is provided with an upstanding flange (114) above the surface of the teat where the depression (112) joins a main surface of the teat, which flange (114) serves to protect the depression (112) against deformation of the main surface of the teat.
Abstract:
A method for preparing carpet by using polyurethane to anneal secondary backing to a greige, comprising fibers attached to a primary backing. The polyurethane monomers are mixed just prior to application to the greige primary backing allowing the relatively low viscosity polyurethane to penetrate the fibers of the primary backing to aid in fiber lock. The polyurethane is puddle between two rollers that coat a layer of polyurethane onto the greige. The polyurethane coated greige is then contacted with the secondary backing before complete polymerization to insure sufficient tack to hold the backings together resulting in a durable carpet requiring a relatively low weight of polyurethane monomers.
Abstract:
A turbine engine component (10) with a non-aluminide protective coating (14) containing silicon and chromium and a process for forming such non-aluminide protective coatings (14). The non-aluminide protective coating (14) is formed by applying a silicon-containing fluid composition to the turbine engine component (10) as a silicon-containing layer (20) and heating the silicon-containing layer (20) to a temperature effective to form the non-aluminide protective coating (14).
Abstract:
A high precision floating point emulator and associated method for emulating subject program code on a target machine where the subject machine base operands possess a different precision than the target machine. The high precision floating point emulator is provided for the emulation of subject program code instructions having a higher precision than that supported by the target machine architecture by utilizing intermediate calculations having values with a higher precision than that supported by the target machine.

Abstract:
A method for preparing a carpet with an integral polyurethane foam carpet pad utilizing a water blown chemistry results in an economical and improved product. The polyurethane is evenly distributed on a spun bond film material, steamed, calendared to a uniform height and cured without the use of a curing oven.
Abstract:
A plurality of resources, typically service operatives, are allocated to a plurality of tasks by a method in which initial information relating to the tasks to be allocated and the resources available to perform the tasks is provided. An initial series of schedules is first generated allocating resources to the tasks, and then modifying the individual schedule of at least one resource in response to updated information. Changes to individual schedules may be made in response to such updated information independently of the schedule generation. The initial, series of schedules may be generated in a two-stage process in which a rule-based system allocates tasks selected as being difficult to allocate (e.g., because they are linked to other tasks). then a stochastic (non-systematic) search system compiles the rest of the schedule. Periodically, the stochastic system may be interrupted to allow a further rule-based system to analyze the schedules created thus far, and fix the best ones in the schedule, so that the stochastic system can then concentrate on improving the remaining schedules. In order to allow the system to handle rapid changes in the requirements for tasks and the resources, on a scale faster than the time required to generate the schedules, a schedule modification system is arranged to make changes in the short term in between schedule updates delivered by the schedule generation system.
Abstract:
After-loader devices, kits, and methods for using the same are provided. Such after-loader devices are useful for loading implants into hollow needles, especially after the needles are inserted into patient tissue. The after-loader devices can be pre-loaded with implants, before the after-loaders are connected to hubs of hollow needles, or loaded thereafter.
