  • Patent number: 11359135
    Abstract: Water-in-oil lattices of water soluble polymers and methods of using the same are presented. The lattices are made, used, and stored having about 15 wt % to 70 wt % polymer solids and further include one or more alkyl ricinoleates. We have found that C1-C6 alkyl ricinoleates added to such lattices facilitate rapid and complete dilution to less than or equal to 1 wt % polymer solids in a continuous water phase. In particular under conditions wherein the water source used to invert the latex is provided at low temperature (?10° C. to 10° C.), or includes a high level of total dissolved solids, or is both low temperature and high total dissolved solids.

  • Patent number: 11322456
    Abstract: A foundation layer having a stiffener and methods of forming a stiffener are described. One or more dies are formed over the foundation layer. Each die has a front side surface that is electrically coupled to the foundation layer and a back side surface that is opposite from the front side surface. A stiffening layer (or a stiffener) is formed on the back side surface of at least one of the dies. The stiffening layer may be directly coupled to the back side surface of the one or more dies without an adhesive layer. The stiffening layer may include one or more materials, including at least one of a metal, a metal alloy, and a ceramic. The stiffening layer may be formed to reduce warpage based on the foundation layer and the dies. The one or more materials of the stiffening layer can be formed using a cold spray.

  • Patent number: 11281191
    Abstract: A single-wire safety system architecture yields reliable safety device monitoring without the need for dual redundant signal channels. The safety system comprises a safety relay and one or more compatible safety input devices connected in series with the safety relay via a single-wire communication circuit. A safety signal with a recognizable pulse pattern traverses the single-wire safety circuit to the safety relay via the safety devices. The safety relay opens its contactors and deenergizes its associated industrial equipment if the pulse pattern is not received and recognized. The safety relay can also be configured to initiate a global emergency stop in response to a loss of a safety function by one of its safety input devices, the global emergency stop instructing other safety relays of other safety circuits to open their contactors and enter safe mode.

  • Publication number: 20220035319
    Abstract: A safety input device for use in a single-wire safety system comprises a fast-switching architecture that allows a safety signal to propagate through the safety device to downstream devices with negligible delay. Rather than placing the signal processor in-line between the signal input and output terminals of the safety device, an electronic switch is placed between the input and output terminals. A signal processor in parallel with the switch monitors the incoming signal and closes the switch if the safety signal is absent, effectively shorting the input and output terminals and allowing the incoming safety signal to pass substantially instantaneously. Loss of the safety signal at the input terminal is immediately reflected by the loss of safety signal output at the output terminal, eliminating processing delay between loss of the safety signal at the input terminal and cessation of the output signal at the output terminal.

  • Publication number: 20210303037
    Abstract: An expansion module for an industrial controller is configured to perform independent local processing of its input signals and to independently generate control outputs in parallel with the primary control program executed by the industrial controller. This can reduce or eliminate response latency for time-critical processes that would otherwise be present if all monitoring and control were performed by the industrial controller alone. This approach can be beneficial for configurations in which the industrial devices that are monitored and controlled via the expansion module require fast response times, as in the case of industrial safety applications.

  • Publication number: 20210040306
    Abstract: Described herein are treated polymers comprising a polyacrylamide homopolymer or a copolymer thereof having at least 30 mol % acrylamide residue content and a weight average molecular weight in the range of 1×105 g/mol to 1×108 g/mol, and 0.1 wt % to 10 wt % of a C1-C6 alkyl ricinoleate based on the weight of the mixture of polymer and alkyl ricinoleate. The polymers are in powder form and include less than about 30 wt % water based on the powder weight. The treated polymer powders dissolve rapidly in water and develop very little or even no insoluble gel upon diluting with water, even when the water is produced water or connate. The treated polymer solutions are useful for in-the-field rapid dilution for applications such as papermaking, flocculation, beneficiation, wastewater treatment, and enhanced oil recovery.
