Publication number: 20240262947Abstract: There is described an acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material. The polyester material is obtainable by polymerizing (i) a polyacid component, with (ii) a polyol component, including—2,2,4,4-tetraalkylcyclobutane-1,3-diol. One of the polyacid component or the polyol component comprises a functional monomer operable to impart functionality on to the polyester resin, such that an acrylic polymer may be grafted with the polyester material via the use of said functionality. Also provided is an aqueous coating composition comprising the acrylic polyester resin and a metal packaging containing coated with the composition.Type: ApplicationFiled: April 8, 2024Publication date: August 8, 2024Inventors: Adam Bradley Powell, William H.

Publication number: 20160212103Abstract: A portable computing device captures imagery from a screen of a second computer, decodes information steganographically-encoded in the screen display, and uses the decoded information to establish a secure session with the second computer. Such technology enables a help-desk staffer to interact with a client's desktop computer, without touching the keyboard of the desktop computer, and without interrupting the client's work. A great many other features and arrangements are also detailed.Type: ApplicationFiled: January 6, 2016Publication date: July 21, 2016Inventors: Geoffrey B. Rhoads, David L.

Patent number: 8740029Abstract: Axial tension is applied to an optical fiber that had been scored at the intended cleave location, wherein the axial tension is applied in a time-varying manner to maintain the stress intensity factor for crack on the fiber within an acceptable level to produce a stable crack growth at a reasonable rate to cleave the fiber without requiring polishing of the end surface. Careful control of the applied tension force with time acts to control the velocity of the propagating crack by maintaining substantially constant stress intensity factor. The applied axial tension force is reduced with time and/or crack growth (as crack propagates). As a result, the strain energy in the fiber material is released by formation of a single plane with an optical quality surface without requiring polishing. A substantially flat optical surface of enhanced optical quality is formed at the cleaved end of the optical fiber.Type: GrantFiled: June 28, 2011Date of Patent: June 3, 2014Assignee: Nanoprecision Products, Inc.Inventors: Michael K. Barnoski, Suresh T. Gulati, King-Fu Hii, Donald Keck, William R. Powell, R. Ryan Vallance

Patent number: 7696115Abstract: Isopipes for use in making sheet glass by a fusion process are provided which exhibit reduced sag. The isopipes are composed of a zircon refractory which has a mean creep rate (MCR) at 1180° C. and 250 psi and a 95 percent confidence band (CB) for said mean creep rate such that the CB to MCR ratio is less than 0.5, the MCR and the CB both being determined using a power law model. The zircon refractory can contain titania (TiO2) at a concentration greater than 0.2 wt % and less than 0.4 wt %. A concentration of titania in this range causes the zircon refractory to exhibit a lower mean creep rate than zircon refractories previously used to make isopipes. In addition, the variation in mean creep rate is also reduced which reduces the chances that the zircon refractory of a particular isopipe will have an abnormally high creep rate and thus exhibit unacceptable sag prematurely.Type: GrantFiled: June 1, 2009Date of Patent: April 13, 2010Assignee: Corning IncorporatedInventors: John D. Helfinstine, Daniel J. Liebner, John L. Martin, Dean V. Neubauer, William R. Powell

Publication number: 20030192349Abstract: The sag rate of fusion pipes (e.g., isopipes (13) used in an overflow downdraw fusion process) is reduced by the application of axial forces (F) to the end regions (23) of the pipe. The axial forces are applied to the end regions below the pipe's neutral axis (19) so that a bending moment is generated which opposes gravitational sagging of the middle of the pipe. The use of such sag-controlling axial forces increases pipe service life by, for example, at least a third.Type: ApplicationFiled: April 11, 2003Publication date: October 16, 2003Applicant: CORNING INCORPORATEDInventors: Gautam Meda, William R.

Patent number: 6295841Abstract: A fused silica glass which exhibits low compaction when exposed to high intensity excimer radiation, also exhibits low optical path distortion after exposure to a high intensity radiation dose. Also disclosed is a method for improving the select ratio of fused silica glass for photolithography, by predicting the optical path distortion of the glass under use by determining the intrinsic densification of the glass at a given number of pulses and fluence per pulse. Mathematical modeling methods are also disclosed for use in producing a fused silica stepper lens having low compaction under high intensity excimer radiation; and for determining optical path distortion caused by high energy radiation in fused silica glass.Type: GrantFiled: February 25, 1999Date of Patent: October 2, 2001Assignee: Corning IncorporatedInventors: Douglas C.

Patent number: 4817762Abstract: A dispenser handle for controlling the speed with which flexible sheet material is stripped from a roll. The handle includes a spindle carrying at one end locking means insertable into the overside opening of a hollow cylindrical core on which the sheet material is wound. The spindle is of reduced diameter and carries, with clearance, a collapsible sleeve which the operator may squeeze to brake the spindle and hence the roll and the rate which the material is stripped from the roll.Type: GrantFiled: November 10, 1987Date of Patent: April 4, 1989Inventor: William R.

Patent number: 4524773Abstract: An improved apparatus for inhibiting self-injurious behavior (SIB) in patients includes a stimulus module for generating and applying an aversive electrical stimulation to the patient's skin and a sensor module and/or remote actuator for actuating the stimulus module in response to a patient's self-injurious behavior. The apparatus uses a near field magnetic link to transmit a coded signal from a sensor module or from a remote actuator to the stimulus module worn on the patient. The stimulus module uses a unique flyback circuit design and the electrical stimulation is tuned to achieve a maximum physiological response with minimal power drain.Type: GrantFiled: August 24, 1983Date of Patent: June 25, 1985Assignee: The John Hopkins UniversityInventors: Robert E.

Patent number: 4141365Abstract: Tissue stimulation apparatus for positive positioning of an electrode-bearing lead proximous to tissue which is to be stimulated electrically, the invention particularly includes a body penetration and insertion assembly which carries an elongated flexible strip of physiologically inert plastic material having at least one electrode positioned thereon into contacting relation with said tissue. The insertion assembly comprises a hollow needle having a slot formed longitudinally along the length of one wall thereof, the slot allowing transverse removal of the flexible lead from the needle after proper positioning of the lead and after removal of the needle from the body. The present slotted assembly allows use of a flexible electrode lead having electrical connections at the external end thereof which are too large to pass through the hollow needle.Type: GrantFiled: February 24, 1977Date of Patent: February 27, 1979Assignee: The Johns Hopkins UniversityInventors: Robert E.
