  • Patent number: 10113314
    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: 20180281017
    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: 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.

  • Publication number: 20180021974
    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: 20170302482
    Abstract: A communication system including a transmitter and a receiver is disclosed. The transmitter transmits frames, at least two consecutive frames containing different training sequences. The receiver receives data communicated from the transmitter over a channel. The receiver combines and jointly processes the at least two consecutive frames transmitted by the transmitter to estimate a channel state of the channel.

  • Patent number: 9295021
    Abstract: Disclosed is a method of measuring time of arrival of a signal transmitted from a transmitter (120) to a receiver (110-n). The method comprises: modulating a plurality of narrowband signal portions onto different carrier frequencies; transmitting, by the transmitter, each modulated signal portion to the receiver; receiving, by the receiver, the transmitted signal portions; estimating the channel impulse response by combining (610) the received signal portions; and measuring (620) the time of arrival using the estimated channel impulse response. Further disclosed is a method of measuring a time of arrival of a signal transmitted from a transmitter to a receiver. The method comprises: estimating a noise level (1310) in an impulse response of a channel between the transmitter and the receiver; finding a first peak (1330) in the channel impulse response that is not noise or a side lobe of a subsequent peak, using the estimated noise level; and measuring the time of arrival (1220) using the first peak.

  • Publication number: 20150368904
    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.

  • Patent number: 8775598
    Abstract: A request for a navigated content associated with a browsing session can be received. The navigated content can be an electronic artifact which can be presented within an interface during the browsing session. The navigated content can be associated with a data source. The interface can be associated with a computing device. A usage metric associated with the navigated content can be collected. The usage metric can be a frequency and/or a duration measurement. The usage metric can be determined to be equivalent to a threshold value of a usage ruleset and can automatically persist within an offline cache the navigated content. A non-navigated content within the offline cache can be programmatically stored. The non-navigated content can be an electronic artifact linked to the navigated content wherein the non-navigated content is not presented within the interface during the browsing session.

  • Publication number: 20140090438
    Abstract: A method of making a rolled aluminum product comprises sawing an aluminum ingot so that the ingot is separated into at least two separate aluminum slabs and rolling at least one of the slabs unclad and unbrazed. In some embodiments, the ingot is sawn horizontally, across its face, as so that, the slabs are equal in length to the ingot. In some embodiments, at least one of the slabs is rolled to form a one of a plate, sheet or foil. The rolling can be hot rolling or cold rolling. Some embodiments further comprise scalping the aluminum ingot. In some embodiments, the sawing of the ingot eliminates or reduces the need to scalp the aluminum ingot and scalping is not performed. Some embodiments further comprise sawing curved edges off the aluminum slabs.
