Patent number: 5736591Abstract: The growth of bacteria in latex is an age old problem. To control the growth of bacteria in latex, chemical bactericides are often added to latex. This invention discloses a technique for providing latex with resistance to bacterial growth. It is based upon the discovery that ions of a metal from Group Ib of the Periodic Chart, such as copper, silver, or gold, will provide latex with resistance to bacterial growth. The subject invention more specifically discloses a latex which is comprised of (1) a polymer, (2) water, (3) an emulsifier and (4) ions of a metal from Group Ib of the Periodic Chart. In most cases, the metal ions will be present in an amount which is within the range of about 1 ppm to about 50 ppm. As a general rule, silver ions are preferred. By utilizing a combination of standard organic chemical bactericides and Group Ib metal ions, the level of chemical bactericides and metal ions needed to satisfactorily control bacteria growth can be significantly reduced.Type: GrantFiled: March 1, 1996Date of Patent: April 7, 1998Assignee: The GoodYear Tire & Rubber Co.Inventor: Edwin Reed Dunn

Patent number: 5677368Abstract: By utilizing the process of this invention, nitrile rubber latices having solids contents of greater than 60 percent can be prepared from standard nitrile rubber latices having solids contents of less than 30 percent. The present invention more specifically discloses a process for increasing the solids content of a low solids nitrile rubber latex which comprises the steps of (1) concentrating the low solids nitrile rubber latex by removal of water therefrom to produce an intermediate solids nitrile rubber latex having a solids content which is within the range of about 35 percent to about 45 percent, wherein the low solids nitrile rubber latex has a solids content which is less than about 30 percent; (2) subjecting the intermediate solids nitrile rubber latex to a pressure which is within the range of about 3.45.times.10.sup.6 Pa to about 6.9.times.10.sup.7 Pa at a temperature which is within the range of about 120.degree. F. to about 170.degree. F.Type: GrantFiled: June 18, 1996Date of Patent: October 14, 1997Assignee: The Goodyear Tire & Rubber CompanyInventors: Edwin Reed Dunn, Gary Lee Burroway

Patent number: 5087808Abstract: A combined optical power and noise meter for measuring both optical power and optical noise includes a detector housing and a photodiode which is disposed in the detector housing. The resistence of the photodiode changes continually in response to the application of optical power thereon. A current to voltage converter applies a bias voltage to the photodiode and transforms an output current therefrom in order to obtain a power voltage which is proportional to the optical power. A first voltage meter is electrically coupled to the current to voltage converter in order to display the power voltage. A noise measuring circuit measures noise in the output voltage of the current to voltage converter and processes the output voltage in order to obtain a noise voltage which is proportional to the optical noise. A divider divides the noise voltage by the power voltage in order to obtain an optical noise to optical power voltage which is proportional to the ratio of optical noise to optical power.Type: GrantFiled: February 26, 1991Date of Patent: February 11, 1992Inventor: Edwin A.

Patent number: 4224579Abstract: An internal mirror metal vapor laser, and in particular, a helium-cadmium laser discharge tube, which is economical, compact and has a relatively long operating and shelf life, the operating life typically exceeding 10,000 hours. A positive column helium-cadmium laser tube of the consumable type and having optical resonator mirrors integral with the tube ends to hermetically seal the tube is provided which includes a relatively large volume cadmium reservoir capable of containing sufficient cadmium for operating life times exceeding ten thousand hours. A heater is applied to the cadmium reservoir for controlling the cadmium vapor pressure. The helium pressure is actively controlled by releasing helium from a high pressure helium reservoir when the helium pressure is less than a predetermined value.Type: GrantFiled: March 13, 1978Date of Patent: September 23, 1980Assignee: Xerox CorporationInventors: Calvin J.

Patent number: 4122409Abstract: The output beam of a laser tube is modulated between a maximum intensity (lase) and minimum (no-lase) intensity levels by varying the laser tube current between corresponding values. The device for controlling the output beam comprises a single transistor provided in the current path of the laser tube, the current therethrough being controlled, or modulated, to provide the modulated laser beam. The device is capable of operating in a plurlity of modes. In the preferred mode, an analog signal is coupled to the transistor control circuitry whereby the laser beam intensity is linearly modulated between the maximum and minimum levels to provide a laser beam having grey scale capabilities. In a second operating mode, a digital signal is coupled to the transistor control circuitry whereby the laser beam intensity is modulated to a constant value between minimum and maximum levels.Type: GrantFiled: March 10, 1976Date of Patent: October 24, 1978Assignee: Xerox CorporationInventors: Calvin J.

Patent number: 3959204Abstract: Latex-based coating materials are prepared frequently by compounding the latex with large quantities of calcium carbonate fillers. Whenever these fillers contain water-soluble calcium and magnesium compounds as impurities latices prepared with anionic emulsifiers are made more unstable, apparently because of reaction between these impurities and the emulsifier. This instability can be overcome by including in the latex a water-soluble fluoride such as ammonium or potassium fluoride in an amount generally under 5 parts by weight per 100 parts dry weight of latex. The process involves adding such a fluoride in an amount sufficient to stabilize the latex, generally under 5 parts per hundred of latex, dry weight.Type: GrantFiled: March 21, 1974Date of Patent: May 25, 1976Assignee: Polysar LimitedInventor: Edwin Reed Dunn
