  • Publication number: 20210032103
    Abstract: Methods for forming alane are described. The method includes addition of toluene at a temperature above the crystallization temperature of alane to a lower temperature solution that includes alane adduct, ether, and toluene. Upon the addition, a crystallization mixture is formed that is at or near the crystallization temperature of alane. The alane of the mixture crystallizes over a period of time to form a high purity alane polymorph.

  • Publication number: 20200140349
    Abstract: A procedure for producing a liquid fertilizing product from a biosolids cake that has been de-watered to a biosolids content of 18% or more. The procedure includes positioning a process amount of the biosolids cake in a reactor vessel, heating the biosolids cake process amount, and adding a quantity of an alkali and mixing it into the process amount of the biosolids cake to form a reactor mixture. The reactor mixture incubated for a period, and then cooled. The alkali includes pH-raising and hydrolysis-procuring components. The quantity of alkali in relating to the biosolids process amount is sufficient that a residual amount of the alkali remains in the cooled reactor mixture, the pH of the reactor mixture remains at a saturation level during and after the incubation period, and the cooled reaction mixture is pumpable.

    Abstract: A method of forming a fertilizer product having a preselected viscosity. The method includes forming a mixture including a biosolids cake having biosolids defining a biosolids content thereof, and alkali in a predetermined amount based on the biosolids content of the biosolids cake. Sufficient process liquid is included in the mixture to result in the fertilizer product having a product biosolids content of up to approximately 16% by weight of the fertilizer product. With a mixing element, the mixture is mixed for a predetermined time period. The mixing element rotates at a predetermined tip speed during the predetermined time period, to produce the fertilizer product.

  • Publication number: 20200105406
    Abstract: Centralized systems execute one or more applications for monitoring and operating a plurality of network enabled medical devices. An indication to start a selected application at the centralized system or at a network enabled medical device is received at the centralized system/network enabled medical device. The selected application may require a license to operate and, at the time the indication is received, may have a first license available. Instead of using the first license, the centralized system/network enabled medical device may determine to inherit at least a portion of a second license to operate the selected application. The centralized system/network enabled medical device may inherit at least the portion of the second license to form an inherited license, where the inherited license enables features of the selected application. Using the inherited license, the selected application is started with the enabled features. Related apparatus, systems, techniques and articles are also described.

  • Patent number: 10581234
    Abstract: A residual current device (RCD) comprises test circuitry which issues intermittent first test pulses each simulating a residual current fault for which a corresponding fault signal is generated. In the case of a fault in which a corresponding fault signal is not received in respect of a first pulse, the RCD attempts to force the load contacts open. The test circuitry further issues intermittent second test pulses at a frequency less than that of the first test pulses, each second test pulse simulating a residual current for which a corresponding fault signal is generated. The duration of each corresponding fault signal is greater than the response time of the load contacts to allow the load contacts to open. If the test circuitry detects that the load contacts do not open, the RCD attempts to force the load contacts open.

  • Patent number: 10392565
    Abstract: Highly efficient and universal biomass conversion methods are described. Methods utilize a base-catalyzed decarboxylation reaction in a conversion process carried out in the presence of excess base to overcome carbonate formation from CO2. Methods can efficiently convert all components of a biomass feedstock to liquid hydrocarbons and carbon dioxide byproduct. The process has several versions: hydrolysis and alcoholysis, etc. The chemical process can be carried out with nearly 100% conversion for any type of biomass feedstock and requires no expensive or complicated pretreatment. The conversion reactions can be carried out at moderate temperatures of 170-300° C. and form a product that can include a mixture of hydrocarbons and oxygenated hydrocarbons, including alcohols and phenol derivatives.

  • Patent number: 10196293
    Abstract: In accordance with one aspect of the invention a testing procedure, a processing procedure and a resulting product are provided whereby sewage sludge is primarily or firstly pre-hydrolyzed in whole or in part by means other than alkali. The alkali is then added to the pre-hydrolyzed product. The pre-hydrolyzed product from step one has a reduced potential for further hydrolysis and is more effectively stabilized in step 2 as a liquid biosolids-containing product or BSP. As a result, in accordance with the invention less of the alkali is used up in the step 2 further alkali-based hydrolysis of the pre-hydrolyzed product. The pH of the BSP product after the step 2 alkali treatment drops less over the period of storage and the BSP product will be better preserved against microbial regrowth.

  • Patent number: 10138122
    Abstract: Methods for forming alane are described. The method drives the alane producing chemical reaction by a mechanical energy source such as a ball mill and includes stabilization of the product with solvent. At least one of the reactants is insoluble in the solvent. Thus, the product is both stabilized and phase-separated from the reactant(s) immediately upon formation. The method can be used to form ?-alane, for instance for use in hydrogen storage.

  • Patent number: 9971871
    Abstract: A system and method for providing updates to medical devices is disclosed. In one example, the medical devices are configured to pull update files in response to the reception of an update message from a server. Once the update files are downloaded by a medical device, the update files can be installed. While the medical device pulls the update files, the medical device can continue with its normal operation. If desired, a user can select which medical devices should be updated, based on any desired factors, such as the physical location of the device, the model of the device, the type of device, and the way the device is being used.
