Anchoring systems for use in cavity wall structures having an inner wythe and an outer wythe constructed of rubble stone are disclosed. The anchoring system employs an anchor fastened to or set within the inner wythe that extends into the cavity and connects to a J-hook. A vertically adjustable veneer tie enwraps the J-hook, limiting lateral movement and front-to-back displacement, and is set within the bed joint of the outer wythe. The anchoring system minimizes cavity size and provides stability for an uncoursed outer wythe equivalent to that of anchoring systems for standards coursed bed joints.

The invention discloses a calixarene additive capable of simultaneously and optionally reducing benzo (a) pyrene and phenol contents in cigarette smoke and an application method thereof. In the invention, deep-cavity P-(1-(4-hydroxyphenyl)-1-methylethyl) calyx (8) aromatic compound is selected as the additive material, and the compound is added in a common and conventional filter tip which bettercan be suitable for a compound filter, with the additive amount being arbitrarily adjusted according to the needs. By using the molecular recognition function and the cavity size select effect of thecalyx (8) aromatic compound, the additive can be optionally combined with the benzo (a) pyrene and phenol molecules in the cigarette smoke. When the additive is added into the filler with the amount of 10mg/per cigarette, 33.2 percent of benzo (a) pyrene content and 41.4 percent of phenol content in the cigarette smoke can be simultaneously reduced, and other chemical compositions in the smoke arebasically not influenced, thus achieving the goal of selective harm reduction.

In embodiments of the present invention, a biodegradable/biodegradable polymer film may be used as a scaffold for tissue engineering scaffolds for engineering organized organs, such as vascular grafts, for example. In one embodiment, an ultraviolet (UV) resin made from a diacrylated biodegradable oligomer is molded into a flexible scaffold having cavities and/or channels. Channel/cavity size may be on the order of micrometers and/or nanometers, and thus the walls may have high aspect ratios. Smooth muscle cells may be deposited in the channels and because of the high aspect ratios, the cells may align along the channels/cavities as confluence is reached.

An injection molding system is disclosed having a self-regulating valve for balancing melt flow. The self-regulating valve includes a control rod configured to balance the melt flow rate through a hot runner system. The self-regulating valve reacts to an injection or melt pressure within the hot runner system and a pre-set force provided by an external force device. The self-regulating valve is an open-loop system as it requires neither a measurement of pressure by a sensor nor feedback from a processor in order to regulate the melt flow. The self-regulating valve mechanically reacts to changes in melt pressure on control surfaces thereof by “bobbing” upwards/downwards to decrease/increase the melt flow accordingly. The self-regulating valve compensates for conditions that affect melt pressure, such as an increase/decrease in melt viscosity, changes in melt temperature, and/or mold cavity size without the use of a processing device.

Provided is a method for the formation of particulate compounds of selectable size characteristics, which method includes supporting a slurried particulate precursor on a porous support; heating the support such that aggregates of the particulate compound are formed, and desagglomerating the aggregates into their component particulate. In a preferred embodiment, an aqueous slurry of alumina particulate which has not undergone the alpha transition is contacted with a porous support having defined pore and cavity sizes, such that the slurry occupies at least some of the interstices of the porous support. The slurry and support are heated such that the alumina precursor slurry undergoes the alpha transition. The alpha alumina product is then particulated. The support is of such a material that it is either lost through combustion during heating or otherwise removable after heating, such as during or after particulation, without destroying the particle characteristics imparted by the porous support. Additionally, in a further embodiment, co-components are added to the slurry in order to impart desired properties to the particulated product.
