Apparatus for tensioning pliable airducts while supporting internal HVAC components are disclosed. An airduct system includes an airduct having a tubular wall of a pliable material. The airduct is elongate in a longitudinal direction. The airduct system further includes a frame including a hoop disposable inside the airduct to support the tubular wall in a radial direction that is perpendicular to the longitudinal direction. The hoop is less flexible than the pliable material. The airduct system also includes a sensor to be attached to the frame to be in fluid communication with a current of air within the airduct. The sensor is to provide a feedback signal that varies in response to a changing condition of the current of air.

An airflow splitter is provided. The airflow splitter includes an inlet, an outlet, at least two splitting member. The splitting member includes a small aperture end and a large aperture end opposite to each other, the small aperture ends of all the splitting members face the inlet, and the large aperture ends of all the splitting members face the outlet. A flow pathway is defined between the small aperture ends and the large aperture ends. The at least two splitting members are sleeved sequentially. In two adjacent splitting members, the large aperture end of one splitting member is located in the small aperture end of the other splitting member. An annular gap is formed between the two adjacent splitting members, and the annular gap is further communicated with the flow pathway.

In an example, a liquid dispenser is for dispensing liquid into a liquid reservoir with reduced foam formation. The liquid dispenser has a baffle element, guiding element and a discharge element. The baffle element is to receive liquid, the guiding element is to guide liquid from the baffle element to the discharge element, and the discharge element is to discharge liquid into the liquid reservoir. The baffle element, the guiding element and the discharge element are arranged in cascade to flow liquid from the baffle element to the discharge element.

A pulsation dampening apparatus for providing a selectively variable orifice size for a reciprocating compressor system includes a rotatable conical cage and a fixed conical cage, the conical cages being aligned along a central axis to form a central cylindrical port. The conical cages each include at least one window or port and have mating contours allowing the conical cages to rotatably slide over one another, allowing their respective ports to be selectively aligned in any configuration to create any desired effective orifice size. In one embodiment, each of the conical cages include a plurality of ports which can be selectively aligned, the relative alignment of the ports determining the effective orifice size of the pulsation dampening apparatus.

The disclosure provides an airflow regulation and control apparatus. A ventilation hole is formed in a windshield in a penetrating manner; a rectangular plate is mounted on the windshield; the rectangular plate is lifted by means of power provided by a lifting wing disposed thereon, and the height of the rectangular plate when moving upwards exceed the height of an upper edge of a main body portion of the windshield; when wind strength is low, the rectangular plate is located at a lower portion under the action of gravity and shields the ventilation hole; when the wind strength is increased, the lifting wing is blown by an airflow to generate upwards lifting force, and drives the rectangular plate to moved upwardly so as to shield an opening in an upper portion of the windshield and block the airflow.

A product tank for receiving a liquid product, and a device for filling containers with a filling product, for example in a beverage filling plant, wherein the product tank includes: an outlet for discharge of the product from the product tank along a discharge direction; and a flow guide device which is arranged in the interior of the product tank and is configured to create a cross-flow oriented towards the discharge direction.

A baffle apparatus for improving a flow deviation of a fluid due to the enlargement of a flow cross-section of the fluid including a plurality of baffle members. Each of the plurality of baffle members has a first part into which the fluid enters and a second part from which the fluid flows out, the first part and the second part are integrated, the first part of each of the plurality of baffle members is at a position where the flow cross-section of the fluid is enlarged and the second part of each of the plurality of baffle members is at the position where the flow cross-section of the fluid is constant, and ends of the first parts are spaced apart from each other by a distance satisfying the equation:

[00001]$d_i=\frac{D}{f\left(i\right).Math.\underset{i=1}{\overset{n}{.Math.}}.Math.\frac{1}{f\left(i\right)}},$

and the second parts are spaced apart from each other by a uniform distance.

A garbage guard apparatus is disclosed herein. In various aspects, the garbage guard apparatus may be mounted in a sump comprising an outflow pipe with an outflow pipe entrance that conveys water from the sump, and the sump may be accessed through a manhole entrance of diameter d. The garbage guard apparatus includes multiple panels, with each panel of the multiple panels having panel width W that is less than diameter d of the manhole entrance to allow for passage of each panel through the manhole entrance into the sump, in various aspects. In various aspects flange is formed on each longitudinal side of each panel with all flanges being symmetric to allow a flange of one panel to mate with any flange of any other panel. The panels when flangeably secured to one another within the sump form a panel assembly, in various aspects. The panel assembly so formed is then attached to the sidewall of the sump about the outflow pipe entrance of the outflow pipe with a lower end below an invert of the pipe entrance and an upper end above a crown of the pipe entrance, in various aspects. When so attached to the sidewall of the sump, the panel assembly defines a passage and the water passes from the sump around the lower end of the panel assembly into the passage and then into the pipe entrance of the outflow pipe with buoyant garbage being retained within the sump by the panel assembly, in various aspects. Related kits, methods of use, and methods of assembly are also disclosed herein. This Abstract is presented to meet requirements of 37 C.F.R. 1.72(b) only. This Abstract is not intended to identify key elements of the apparatus and related kits and methods of use disclosed herein or to delineate the scope thereof.

Methods and systems are provided for a filler inlet of a fuel fill line of a motorized vehicle. In one example, a filler inlet includes a fuel/air separation chamber extending at an angle relative to an opening of the filler inlet, with the opening adapted to receive a fuel nozzle. Fuel may be guided from the fuel nozzle toward a curved wall of the fuel/air separation chamber by a flow guide, and the fuel may separate from entrained air within the fuel/air separation chamber.
