Abstract: FIGS. 1-16D & 66A-92D disclose a large variety of methods of forming the headgear for use in combination with a breathing apparatus including a unitary plastic core within textile casings. In some configurations, the plastic core material penetrates or bursts-through the textile casing of the straps. Some configurations include over moulding, alignment posts, T-joints and joint housings with injection aperture. FIGS. 17-65 & 93A-94C disclose a large variety of different headgear arrangements including top strap, front strap, rear strap and pairs of straps extending from the mask above and below the ear to meet behind the ear. FIGS. 95-121B disclose a large variety of connectors connecting the headgear assembly to the mask assembly where the headgear, mask and connector form a closed loop when the connector is disengaged with the mask assembly.

Abstract: Art paints or base materials can be manufactured from discarded materials such as architectural paint to reduce waste paint and to produce high quality art paints at a low cost and with a low ecological impact. Discarded architectural paint or other feedstock material is sorted, treated, and mixed with additives such as colorant, polymers, or monomers in a dispersion to produce a high-quality art paint. The high quality art paint can have selected traits, such as color, sheen, dry time, viscosity, or other properties, that are desirable for art paints but not traditionally present in the source feedstock materials.

Abstract: Provided are methods, apparatuses and washing machines that involve the filtration of microparticulate from liquid effluent of laundry apparatuses and systems. For example, steps involved in the inventive method may include: collecting the liquid effluent from the output of the outer tub of the washing machine; establishing a continuous high-pressure state to at least a portion of collected liquid effluent by a pumping device, based at least in part on a signal; and directing a threshold amount of high-pressure liquid effluent by a pumping device through a microparticulate filtration system, wherein the threshold amount is based at least in part on a first aspect of the pumping device and/or a microparticulate filtration system.

Abstract: A tool for separating blocks and other elements from an assembly of toy construction elements is disclosed. The tool may include a coupling end that can attach to pegs and/or openings in a block and is configured for easily prying off the block. The tool may include a moving member that can be used to configure the coupling end in two different configurations for coupling to either the top or bottom of a block.

Abstract: A method and an apparatus are provided for using a capacitor chain to perform charge sharing and Anger logic to determine, for charge pulses arising from gamma-ray detection, a row position along an array of scintillation-based gamma-ray detectors. Further, high-pass filters configured at the ends of the capacitor chain perform pulse shaping to preserve timing information. To determine the column position for charge pulses, a two-stage summing amplifier configuration is used with weighting amplifiers controlling the relative gain of the second-stage amplifier with respect to respective columns in the array. Each detector element in the array is a silicon photomultiplier (e.g., Geiger-mode avalanched photodiodes biased above breakdown voltage). Position information can be generated by Anger logic on four outputs from the second-stage amplifiers. Energy and timing information can be generated as a sum of the four outputs from the second-stage amplifiers.

Abstract: An embodiment of the present invention provides a toy roller coaster assembly having magnetically attachable track sections and an integrated audiovisual system. The assembly can include a magnetic lift, a magnetic bridge, and a magnetic U-turn. A controller can control the frequency by which a magnetic lift delivers balls to an uppermost track section and can produce audio and/or visual effects in response to signals from sensors that detect passing balls. Joint members of the assembly can magnetically connect the track sections to each other and to a plurality of vertical supports, to provide a variety of configurations. The controller can generate voice and music samples, sound effects, graphic displays, animation sequences, and video clips in conjunction with the motion of the balls through the circuit of the roller coaster assembly.

The channel having an upper opening along the upper surface of the molding. An anchor insert extends in the channel and has an exposed face at the upper opening of the channel for attaching a flashing cap to the anchor insert to thereby secure the flashing cap to the anchor insert.

Abstract: A support roller device for heavy curtains of the type used on curtain-sided cargo carrying vehicles wherein the roller has a pair of spaced wheels for engaging rails of a track member that has a downwardly opened slot between the rails. A guide block with longitudinally spaced flanges of a low friction material is positioned in the track slot and is only slightly narrower than the track slot to guide the device and roller along the track. The guide block is a separate member mounted on a metal hanger from the roller in one embodiment and is formed as an integral part of the hanger in a second embodiment.
