  • Patent number: 10914073
    Abstract: An asphalt shingle manufacturing machine that includes a curtain die for applying a liquid release layer on an asphalt coated substrate. The moisture of the liquid release layer evaporates leaving a dispersed solid particulate release layer. The curtain die includes a first body section and a second body section with a shim disposed between the body sections to define a distribution channel. The second body section may include chamber manifold defined therein to store a volume of liquid release agent. The distribution channel places the chamber manifold in fluid communication with a discharge outlet of the curtain die in order to disperse a volume of liquid release agent from a chamber manifold out of the discharge outlet. The shim may be configured to define a width of the distribution channel to determine the flow rate and discharge pattern of the liquid release agent.

  • Patent number: 10894337
    Abstract: According to the present invention there is provided a method of treating timber with a creosote-containing preservative formulation adapted for use at substantially ambient temperature. The formulation comprises: creosote; one or more surfactants such that when diluted with a predetermined quantity of water, the creosote is present as an oil-in-water macroemulsion or microemulsion; and optionally, an anti-foaming agent and/or a fire retardant. It is found empirically that the inventive concentrate allows for the use of creosote, a known-effective biocide, without many of the drawbacks inherent in such use.

  • Publication number: 20200392412
    Abstract: A two-part flame-retardant, a flame-retardant oriented strand (OSB) and method for forming a flame-retardant OSB is provided. The two-part flame-retardant composition includes an aqueous solution containing a water-soluble flame-retardant and a flame-retardant powder that is incorporated into an oriented strand board without substantially affecting the mechanical properties of the oriented strand board. The method includes applying the aqueous solution containing a water-soluble flame-retardant to an oriented strand board furnish and applying a flame-retardant powder to the wetted furnish, without requiring an additional drying step.

  • Patent number: 10697179
    Abstract: An asphalt shingle having an asphalt-coated substrate sheet with a top surface and a bottom surface, wherein a liquid release layer is applied on the bottom surface of the asphalt shingle instead of conventional backing particulates. The liquid release layer may help the shingle proceed through the manufacturing machinery without sticking and may prevent the adhesion of the bottom surface of the asphalt shingle to an adjacent shingle in a stack of shingles upon experiencing a pressure up to around four pounds per square inch, a temperature of around eighty degrees Celsius or below. The liquid release agent may also prevent adhesion of adjacent shingles in a stack at various temperature and pressures for at least fourteen days.

  • Publication number: 20190376292
    Abstract: A lightweight roofing shingle comprising a saturated mat having an exposed side and an unexposed side wherein a fabric reinforcing layer substantially replaces the bottom asphalt coating and the backing aggregate on the unexposed side of a conventional shingle. The lightweight shingle will have a top asphalt layer applied to the exposed side of the mat and a layer of granular material applied to the top asphalt layer opposite the mat per conventional construction, and the fabric reinforcing layer is adhered directly to the unexposed side of the saturated mat. In one embodiment, the fabric reinforcing layer covers an entire area of the unexposed side of the saturated mat. The reinforcing layer may preferably be a nonwoven fabric made from PET or polypropylene. The lightweight roofing shingle may also include a release tape layer applied to the reinforcing layer opposite the saturated mat.

  • Publication number: 20190303464
    Abstract: A non-transitory machine-readable storage medium stores instructions that upon execution cause a processor to, in response to initiation of a data indexing for a search concept, retrieve content of a first data source via a data connector, the retrieved content including a reference to a second data source. The instructions further cause the processor to, in response to a determination that the retrieved content of the first data source is relevant to the search concept: index the retrieved content of the first data source; retrieve content of the second data source based on the reference; and determine whether the retrieved content of the second data source is relevant to the search concept.

  • Publication number: 20190271160
    Abstract: Disclosed is a release material that can be applied as a liquid, gel, emulsion, foam, etc. in a shingle manufacturing line. The release material can also be used in the manufacturing of roll roofing. The release material primarily constitutes an emulsion of polymers that can be cured with heat, IR light or other methods. Silicone may also be included in the emulsion which assists in releasability. The release material can be sprayed or extruded on to the surface of the shingle in an automated fashion, eliminating the necessity for operator interaction.

  • Publication number: 20190242057
    Abstract: Disclosed is a shingle that uses a polyester sheet as a substrate layer. The polyester sheet has a sufficient weight and is needled and formed from two layers to resist shrinking upon cooling after the heated asphalt layers are applied to the polyester substrate sheet 102. In addition, additives may be included in the asphalt to lower the softening point temperature of the asphalt that further reduces shrinking of the polyester substrate 102 or allows other polymers that are more fire retardant to be used. Fire retardants can be placed in the polyester sheet fibers, placed in the bonding agent for the polyester fibers, or the polyester sheet can be coated with the fire retardant. Alternatively, or in addition to treating the polyester sheet 102 with fire retardant, fire retardant materials such as ammonium sulfate can be added to the liquid asphalt prior to application of the asphalt layers.

  • Patent number: 10318146
    Abstract: A touch screen computing device with an easy to use user interface. The computing device provides on the touch screen a control area associated with a content viewing area. Touch inputs that initiate in the control area, even if they extend into the viewing area, are interpreted as commands that manipulate the display of content. Other touch inputs are interpreted as interactions with displayed content. The control area may be formatted to allow easy access by a user holding the computing device. Through such an interface the user may input commands specifying direct manipulation of the content, without frustration that can occur from the computing device incorrectly interpreting those commands as interaction with the content.

  • Patent number: 10027037
    Abstract: An embodiment is directed to a receptacle terminal for receipt of a mating terminal therein. The receptacle terminal includes a contact portion which has a bottom wall and resilient contact arms. The resilient contact arms extend from opposed sides of the bottom wall. Each of the resilient contact arms has an opening extending therethrough with a first resilient contact section and a second resilient contact section extending on either side of the opening. The first resilient contact sections and the second resilient contact sections have arcuate portions which extend from the bottom wall to mating terminal engaging members. The first resilient contact sections and the second resilient contact sections generate a contact force when a mating terminal is inserted into the terminal.

  • Patent number: 9915590
    Abstract: In a material sample separation and collection system, a sample is obtained by airflow separation. The system and attendant methods collect a complete sample over a defined period of time by modulating one or more pressure balancing valves, thus allowing for a variable flow rate of materials through the system even while the fan or other source of airflow operates at constant speed. The sampling rate, which is based on how quickly or slowly materials enter and pass through the system and into a collection vessel, is automatically modulated in real time based on sensor data.
