Title: Composite concrete material and method of making a composite concrete material
Inventor: Gogol John Ronald
IPC: E02D29/14
Filed: 2019-09-13
Abstract: A lightweight composite concrete cover is provided for subgrade trenches and vaults. The lightweight cover comprises at least one low density layer that has a low density filler material such as polyethylene terephthalate beads. The low density layer substantially reduces the overall weight of the cover, and the remaining layers provide sufficient structure for the cover to pass rigorous load and chemical exposure testing. In addition, a method of manufacturing a lightweight cover is provided that promotes the combination of different layers of the cover and the cross linking of polymer chains between layers of the cover. The lightweight cover has substantial weight savings and also meets rigorous testing standards such that a worker can manually remove the cover, transportation costs are realized, and worker safety is improved.

Title: Bar lock assembly
Inventor: DOLNIK JOHN E
IPC: E05B83/08
Filed: 2019-10-03
Abstract: A bar lock assembly including a lock rod defining a rotational axis for the bar lock assembly. The lock rod includes a first elongated lock rod portion and a second lock rod portion. A lengthwise section of the second lock rod portion telescopically extends from a first end of said first lock rod portion when the bar lock assembly is in a first condition. The second lock rod portion is substantially retracted within the first lock rod portion when the bar lock assembly is in a second condition. An elongated handle with opposed ends extends from the lock rod. One end of the handle is pivotally connected to the first lock rod portion to effect rotational movements of the bar lock assembly about the rotational axis. The handle moves in a fixed arc about a fixed pivot point whereat the handle is connected to the first lock rod portion. Linkage connected between the handle and the second lock rod portion telescopically moves the second lock rod portion relative to the first lock rod portion in response to pivotal movement of the handle about the first pivot point. To enhance the ergonomics of this bar lock assembly, the linkage and handle are configured such that an included acute angle ranging between about 35°and about 50° is defined between the handle and the longitudinal axis of the bar lock assembly when the bar lock assembly is in the first or locked condition.

Title: Methods and systems for in-device interference mitigation
Inventor: TERRY STEPHEN E
IPC: H04W36/30
Filed: 2011-08-13
Abstract: Methods and apparatus for mitigating in-device interference are described. The methods may include an in-device interference event (e.g. an interference situation), and the processing of events may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur in case a co-existing technology may be activated. The network may signal to the device a list of frequencies or RATs that it may be allowed to measure and handoff to. A network may provide a scaling value that the device may use to speed up reaction to the interference. The device may apply a scaling factor to an "out of synch' counter and/or the radio link failure (RLF) timer used for the RLF procedure. The device may apply different scaling factors for the measurements and time to trigger events. The device may trigger a report to the network requesting gaps for an alternate RAT.
