Abstract: A beverage preparation system, a method of preparation and a device for securely engaging with a cup unit for preparing a beverage. A potable liquid is supplied within the cup unit but kept separate from a capsule brewing element containing a predetermined quantity of edible ingredients also disposed within the cup unit. The brewing element is constructed in a shape which retains its integrity without any external support even under pressure such as needed for espresso drink preparation. The beverage preparation device operates by extracting the potable liquid from the cup unit, processing it in a heating/cooling chamber, and returning the processed liquid at a predetermined pressure and time duration to the cup unit. The operation is performed in accordance with preprogrammed instructions associated with an instruction source provided on a sealed cover of the cup unit.

Abstract: A cutting system for a lawnmower or the like includes multiple blade assemblies driven by a motor, each motor independently operable with respect to each other motor. The blade assemblies are arranged into a cutting system with a length less than that of the combined length of the blades of the blade assemblies. Blade assemblies include components that align so as to balance the blade upon rotation. These components allow for a single user to attach and disengage the blade from the motor, or portion rotated thereby, with hands alone, absent tools.

Abstract: A brewing element comprising an envelope for storing at least one comestible brewing ingredient therein; and an attachment means for removably attaching the element to a container, the element having formed therein a central inlet for admitting pressurized, heated water and a peripheral outlet for releasing a mixture of the at least one comestible brewing ingredient with the pressurized, heated water, wherein when the brewing element is incorporated into an operating beverage brewing system, the capsule releases the mixture multi-directionally through the peripheral outlet to provide a brewed beverage into the container.

Abstract: A portable beverage preparation device comprising a drink container containing a predetermined volume of a potable base liquid, at least one beverage preparation of a predetermined quantity; at least one sealed compartment for confining the beverage preparation, and a dispenser means for dispersing the at least one beverage preparation into the base liquid within the drink container; wherein the drink container and the at least one sealed compartment are in close physical proximity to each other and separated by at least one thin membrane which, when inwardly perforated by the dispenser means, disperses the at least one beverage preparation into the base liquid to make a beverage ready to drink.

Abstract: A tacker for applying a rotary tack, including a drive shaft coupled to a trigger, wherein operating the trigger causes rotation of the drive shaft, a magazine that holds a rotary tack rotatingly connected to the drive shaft, and an articulated applicator arm including a rotatable output shaft rotatingly connected to the magazine, wherein the magazine is proximal to the articulated applicator arm, the articulated applicator arm including one or more pivoting links, each pivoting link including a link shaft, wherein operation of the trigger causes the driver shaft and the one or more link shafts to rotate so as to distally advance the rotary tack from the magazine past the one or more pivoting links.

Abstract: A tacker for applying a rotary tack, including a drive shaft coupled to a trigger, wherein operating the trigger causes rotation of the drive shaft, an articulated applicator arm pivotally connected to the drive shaft at a pivot, the articulated applicator arm including a rotatable output shaft connected to a magazine that holds a rotary tack, and a clutch mechanism which, at initial movement of the trigger, has a first orientation that causes the articulated applicator arm to pivot about the pivot until reaching a stop, and has a second orientation wherein upon continued movement of the trigger, the clutch mechanism permits the drive shaft to rotate the output shaft and cause application of the rotary tack from the magazine.

Abstract: Mesh deployment apparatus including a deployment rod having a proximal handle and a distal roller portion, the roller portion having a mesh-sheet attachment member to which a mesh-sheet is attached. The roller portion is articulated with respect to the deployment rod by means of a joint, and a manipulating member is coupled to the roller portion for moving the roller portion about the joint to a position such that the roller portion is not collinear with the deployment rod.

Abstract: A tacker for applying a rotary tack, including a tacker for applying a rotary tack, including a handle with a first trigger assembly and a second trigger assembly, the trigger assemblies being coupled to an articulated applicator arm which is disposed through a drive shaft connected to the handle, the first trigger assembly operative to apply a rotary tack from a distal end of the applicator arm and the second trigger assembly operative to bend the distal end of the applicator arm, wherein a longitudinal axis of the handle is tilted with respect to the drive shaft.

Abstract: A rotary tack including a helical body constructed of a resorbable material and having a closed-loop base and a helix of spiral coils that extend from the base which terminate in a tip for piercing tissue, wherein each of the coils has a cross-section with an inner perimeter including an arcuate portion and a straight portion contiguous to each other.
