  • Patent number: 10704837
    Abstract: The present invention relates to a condenser for condensing gasses. The condenser comprises: an inner tube (1) having a bore (3) therethrough; an outer tube (2) having a bore (8) therethrough and two ends, the inner tube (1) passing through the bore of the outer tube (2); and a seal (15, 16) at each end of the outer tube. The outer tube has exterior and interior fins and is sealed to the inner tube so as to define a sealed space (11) between the inner tube and the outer tube. The space (11) is adapted to contain a liquid in contact with the inner tube (1) and the outer tube (2). The invention further relates to a method of condensing a gas using the condenser, a process of making a chemical using the condenser and a kit adapted to be assembled into the condenser.

  • Publication number: 20200200202
    Abstract: A fastener system for securing a panel to a frame comprises one or more rotating fasteners installed in the perimeter edge of the panel. In operation, one or more cam surfaces of the fastener engage receiving surfaces of a receiver on the frame such that, upon rotation of each fastener, the panel is drawn toward the frame. In some embodiments, the panel is moved in a first direction parallel to the panel and a second direction perpendicular to the panel or in a composite diagonal direction inclined relative to the panel. The fastener system may facilitate compression of seals disposed along the perimeter edge of the panel and between a side of the panel and rabbet ledge of the frame and may further facilitate removal and maintenance of the panel.

  • Patent number: 10688091
    Abstract: Described is a composition comprising (a) a population of particles of an aripiprazole prodrug having a volume based particle size (Dv50) of less than 1000 nm and (b) at least one surface stabilizer comprising an adsorbed component which is adsorbed on the surface of the aripiprazole prodrug particles and a free component available for solubilisation of the aripiprazole prodrug. The surface stabilizer to prodrug ratio provides the optimal quantity of free surface stabilizer for the purposes of producing a lead-in formulation. Also described are methods of treatment using the aforementioned composition.

  • Publication number: 20200165174
    Abstract: The present invention relates to increasing longevity of the nitrogen content of soil through improved liquid delivery formulations of nitrification inhibitors. The liquid formulation can also be comprised of nitrification inhibitors and optionally urease inhibitors that are blended solutions of each. The nitrification inhibitors are present in a mixture that comprises both a protic and an aprotic solvent system. The novel formulations are designed to be applied to fertilizers, especially urea and manure based fertilizers. The delivery formulations provide an environmentally sound and inherently safe solvating system that improves the storage stability of the urease inhibitors by utilizing liquid organic non-water containing solvents, maintains the nitrification inhibitors in solution to storage temperatures of at least 10° C., and provides improved application to fertilizer of nitrification inhibitors.

  • Patent number: 10653841
    Abstract: A drive mechanism suitable for use in drug delivery devices is disclosed. The drive mechanism may be used with injector-type drug delivery devices, such as those permitting a user to set the delivery dose. The drive mechanism may include a housing, a dose dial sleeve, and a drive sleeve. A clutch is configured to permit rotation of the drive sleeve and the dose dial sleeve with respect to the housing when the dose dial sleeve and drive sleeve are coupled through the clutch. Conversely, when the dose dial sleeve and drive sleeve are in a de-coupled state, rotation of the dose dial sleeve with respect to the housing is permitted and rotation of the drive sleeve with respect to the housing is prevented. In the de-coupled state, axial movement of the drive sleeve transfers force in a longitudinal direction for actuation of a drug delivery device.

  • Patent number: 10649233
    Abstract: An unobtrusive augmented reality (AR) system can be used to assist the wearer in every day interactions by projecting information from the contact lens display onto the retina of the wearer's eye. The unobtrusive augmented reality system includes a necklace and a contact lens display that are unobtrusive to the wearer and the wearer's surrounding environment. The necklace of the unobtrusive augmented reality system generates power and data for the contact lens displays. The necklace and contact lens display include conductive coils inductively coupled by a magnetic field. The inductive coupling allows data and power generated by the necklace to be transferred to the contact lens display. A projector in the contact lens display projects images generated from the data onto the retina of the wearers eye.

  • Patent number: 10311548
    Abstract: Examples described herein improve the quality of the video frames that are rendered and displayed. A system is configured to generate render targets based on instructions received from a source of video content. The system is configured to create and/or access a selection parameter and use the selection parameter to identify one or more of the render targets to be scaled. Once identified, the system scales a native size (e.g., a native resolution) of an identified render target to a larger size (e.g., based on a predetermined scaling factor), thereby generating a higher density render target. The higher density render target, or a corresponding higher density render target texture (RTT), can be used in a rendering pipeline to produce a video frame in a higher output resolution (e.g., 4k resolution) compared to the output resolution specified in the instructions (e.g., 720p resolution).
