IPC: A61M5/40
Filed: 1992-10-28
Abstract: ABSTRACT:      An automatic-closing type of dripping set, in which  a dual  cap  float  is used for  automatically  controlling  an injection fluid to flow out and to stop flowing; the dual cap float  includes a round rod, an upper cap and lower cap;  the round  rod is movably mounted in an outlet in a  base,  while the  upper and lower caps are mounted across the base.  Since the  dual cap float mounted across the base in limited  in  a given space to move up and down, the dual cap float would not affected  by  the  motion  of  the  dripping  set.  When  the injection fluid above the base is drained off, the upper cap will shut the outlet automatically as a result of the  weight thereof and the sucking force of the fluid so as to shut  and seal  the  dripping set, and to make  the  structure  thereof simple.

Title: System and method for dectecting cutting tool failure
Inventor: HAMIDIEH YOUSSEF A
IPC: B23Q17/09
Filed: 1993-06-22
Abstract: Abstract A system and method for detecting failure of a cutting tool during its operation by utilizing a frequency domain analysis of the vibration of the cutting tool.  A signal is generated based on vibration of the tool during its operation to determine the energy of the signal in a plurality of signal component frequency bands.  The energy of the signal in each of the plurality of frequency bands is compared to corresponding threshold values to generate a tool failure signal when the energy of the signal in a preselected number of frequency bands exceeds the corresponding threshold values for a predetermined period of time.  In a second embodiment, time domain analysis of the signal generated based on vibration of the tool is utilized in addition to frequency domain analysis.  The averaged signal is compared to a threshold signal to generate a tool failure signal when both the energy of the signal in a preselected number of frequency bands exceeds the corresponding threshold values and the averaged signal exceeds the threshold signal.

Title: Method of attaching adhesive to a tabbed absorbent article
Inventor: MENARD MICHAEL J
IPC: A61F13/56
Filed: 1993-09-01
Abstract: A method for making an absorbent article, such as a sanitary napkin, having tabs. A first series of patches of a hot melt type pressure sensitive adhesive are applied to one side of a double-sided release strip. The release strip is then placed against the central portion of the absorbent article so that the first adhesive patches bond to the central portion. A second series of patches of the adhesive are applied to the other side of the double-sided release strip and tabs are folded over the central portion so that the second adhesive patches bond to the tabs.      Since the release strip has been coated with a release agent, such as silicone, on both of its sides, the first and second patches of adhesive bond to the central portion and the tabs, respectively, with greater tenacity than they did to the release strip. when the user removes the release strip prior to use, the first and second adhesive patches remain on the central portion and the tabs. Thus, a hot melt type of pressure sensitive adhesive is applied to the central portion and the tabs without danger that they will be scorched by the heat of the hot melt adhesive as it leaves the glue gun.

Abstract: ABSTRACT   In the present invention, the lowering of physical properties is minimized by bonding matrix resin and starch chemically using a coupling agent in the presence of an organic acid catalyst, at the same time lowering of the production cost is achieved by simplyfing the process.   In the prior arts, the problems associated with low physical properties caused by starch incorporation were approached only in terms of enhanced physical interacting strength between matrix resin and starch.   The purposes of the present invention are to provide a biodegradable polyethylene composition chemically bonded with starch comprising 100 parts by weight of matrix resin, 5-400 parts by weight of biodegradable incorporating material, 0.01-10 parts by weight of coupling agent, 0.01-1.0 parts by weight of radical initiator, 0.01-5 parts by weight of Lewis acid catalyst, 0.01-10 parts by weight of autoxidizing agent and 0.01-10 parts by weight of plasticizer and to provide a process for preparing thereof.   The biodegradability of the polyethylene composition prepared by the present invention was determined in addition with reclamation test and shown to be excellent at a content of more than 10 wt.% of starch.

Title: Method and apparatus for making optical components by direct dispensing of curable liquid
Inventor: KEYWORTH BARRIE P
IPC: B29D11/00
Filed: 1994-03-01
Abstract: A method of forming an optical element on the surface of a substrate by ejecting a curable light guide forming liquid from a nozzle onto the substrate and curing the curable light guide forming liquid. A waveguide may be formed by moving the nozzle in a linear pattern over the surface of the substrate during ejection of the liquid from the nozzle. Curing the liquid may include exposing the liquid to ultraviolet radiation, and the radiation may be applied to only a small portion of the liquid. A multilayered waveguide may be formed by ejecting a further light guide forming liquid onto the first and curing it. A core and cladding may be formed simultaneously by ejecting core forming liquid from an inner tube and cladding forming liquid from an annulus about the inner tube. The waveguide may be formed in a groove, and a splitter may be formed by branching a second waveguide from a first, or by laying out two parallel waveguides and connecting them. Apparatus for forming a light guide on a substrate includes an xy movable support for the substrate, and a container having a nozzle, the nozzle being movable in relation to the substrate, and a dispenser to regulate dispensing of liquid from the container. Liquid curing radiation may be provided through a source of UV light. The nozzle may be formed of a first central tube and a second outer tube disposed about the first central tube to form an annulus between them. A microlens may be formed by holding the nozzle stationary during dispensing.
