The muzzle brake can include a first muzzle chamber fluidicly coupled to the first expansion chamber and a second muzzle chamber fluidicly coupled to the second expansion chamber. Multiple baffles can be positioned within the external can between the first expansion chamber and the second end of the external can, including first and second baffle sets that each include a first baffle and a second baffle. The assembly can also include an endcap coupled to the second end of the external can.

Abstract: A method of making battery plates for lead-acid batteries includes providing a strip of material comprising lead; and punching material out of the strip to form a grid comprising wires having a non-rectangular cross-sectional shape by utilizing a die set comprising a plurality of male die components and female die components, wherein each of the male die components comprises a first portion having a first cross-sectional shape and a second portion having a second-cross sectional shape. A single punch of the material creates a hole in the material and also forms the periphery of the hole.

Abstract: The presently disclosed subject matter is directed to an adaptor that can be used to eliminate the gap present between the motor housing and the propeller in conventional trolling motors. Particularly, the disclosed adaptor comprises a first shell and a second shell that attach together and surround the base of the trolling motor propeller therebetween. As shown, the propeller blades extend from one or more apertures in the adaptor. The adaptor attaches to the trailing end of the motor housing and is maintained on the drive shaft through the use of one or more fasteners.

Abstract: For a block of memory cells interconnected by single-ended bit lines, a sense amplifier receives the input from a single-ended bit line to determine the logic state of a selected memory cell connected to the single-ended bit line. The sense amplifier also receives a reference voltage generated from a base-emitter voltage of a emitter follower bipolar transistor. The base-emitter voltage is controllably divided by a voltage divider network with selectable resistive elements to tune the reference voltage.

Abstract: PFRs for running multiphasic processes are disclosed. The PFRs are single or multi-chamber devices having at least three types of regions (a liquid-contacting region, a gas-contacting region and a Ssquid-coSection region), and a porous substrate providing fluid communication at least between the liquid-contacting and gas-contacting regions. Removal of liquid from the porous substrate, such as by collecting the liquid as it flows off the bottom of the porous substrate in the Siquid-coSSection region or such as by evaporation of the liquid from the porous substrate in the evaporation region supports a continuous flow process. Methods of using the PFRs are also disclosed, for example methods of using the PFRs as photobioreactors for cultivating photosynthetic microorganisms, for producing fermentable sugars, for producing ethanol, for fermenting synthesis gas and producing single cell protein from natural gas.
