An icing dispenser having an expandable elastic reservoir on the handle proximal end which when loaded expands a reservoir bladder under an elastic bias that tends to return the bladder to its unexpanded condition, therein uniformly impressing constant pressure on the icing within the reservoir. A reservoir neck extends from the bladder through a handle passageway to a decorator icing tip. A butterfly valve within the reservoir neck modulates an amount of icing flowing through the tip with butterfly ends angled parallel to the passageway and urged into the pliable neck at a preferred angle, slightly deforming the neck to effect a valve seal. The handle is adapted for operation in an operator's fingers as a writing instrument with icing extrusion modulated by a lever on the handle being adjusted relative to the handle by the fingers.

A spring system comprising flat plate-springs with one end mounted rigidly to an un-sprung first base and the opposite end mounted rigidly to a sprung second base. The spring system is fitted with cams as strain-control surfaces, mounted tangent to the plate springs and spaced progressively from the said plate-springs beginning at the tangency. The strain-control cams are movable to provide for adjustable spring rates, actively repositioned upon demand therein providing an adaptive active spring-rate system or suspension.

A transformable holster () for a portable product () can include a lower base portion () having a receptacle for receiving a lower portion of the portable product, and an upper base portion () coupled to the lower base portion. The lower base portion moves relative to the upper base portion and the transformable holster can transform into a compact holster when the upper base portion is detached from the portable product. The holster can optionally include an intermediary portion () pivotably hinged to the lower base portion and the upper base portion and a biasing member such as one or more spring loaded pivot joints (and/or ). In one alternative () using a dove tail arrangement, one among an upper base portion () and the lower base portion () can slide into each other to form the compact holster.

A tube cutting machine comprises a tube secured in a chuck tightened against an outer tube wall and by a mandrel expanded within the tube against the tube inner wall opposite the chuck. A blade with a conical body side on the tube body side advances into the tube at the body side angle, eliminating longitudinal force against the tube body and accumulation of tube material on the blade body side. In alternative embodiments, either the tube or the blade can rotate. As the blade edge enters the tube wall, the blade end side, opposite the body side is also conical and pushes the tube cut portion longitudinally away from the tube body, causing the tube before the blade to neck under the longitudinal force imposed by the blade end side. The blade is reversed when the neck weakens and is unable support the tube cut portion but has not yet broken, referred to as the failure point. The blade is then withdrawn and the neck is snapped off. The failure point is detected by a rod urged transversely against the tube end. When the tube end begins to move indicating pending tube wall failure, the blade is immediately withdrawn from the tube. The rod continues to move the tube cut portion, snapping it from the tube body. The resulting cut does not have any burrs radially inward or outward of the tube wall, though there is a small burr extending longitudinally from the tube wall.
