Abstract: A composition includes bone and collagen, wherein the collagen has been acid treated, and cross-linked via dehydrothermal treatment or by a cross-linking agent (e.g., a citric acid derivative) under a compressive force of at least approximately 40 MPa.

Abstract: A method of processing an acellular tissue matrix to give a particulate acellular tissue matrix includes: cutting sheets of dry acellular tissue matrix into strips; cryofracturing the dry acellular tissue matrix strips at cryogenic temperatures; separating the resulting particles by size at cryogenic temperatures; and freeze drying the fraction of particles desired size to remove any moisture that may have been absorbed to give a dry particulate acellular tissue matrix. Rehydration of the dry particulate acellular tissue matrix may take place just prior to use. The particulate acellular tissue may be applied to a recipient site, by way of injection, spraying, layering, packing, in-casing or combinations thereof.

Abstract: A method of determining the dimensional characteristics of a biological object included: measuring without physical contact or disruption of sterility the length, width and height above or below a reference plane of the biological object with an optical distance measuring device thereby creating a data set; and processing the data set in a computer so as to determine the dimensional characteristics of the biological feature. Preferably the optical distance measuring means is a laser based distance measuring device and the storage of x axis values, y axis values and distance values is in the electronic memory of a computer. The biological surface may be a wound bed or a dermal surface, or alternatively the biological surface may be vascular tissue including heart valves, veins and arteries.

Abstract: An arrow rest assembly attached to a bow is designed to be horizontally movable in order to clear the fletching on a released arrow. The arrow rest assembly incorporates a flexible positioner to position the arrow away from the handle of the bow, in line with the bow string and in clearance of the fletching. An arrow rest holds the arrow in position while the bow is drawn and the arrow is aimed. The arrow rest assembly has a triggering control which responds to the movement of the bow string after the arrow is released; such triggering control retracts the arrow rest from its extended holding position to its retracted clearing position before the fletching of the arrow passes by the arrow rest. The triggering control can be adjusted relative to the bow string in order to vary the timing of the arrow rest's retraction.

Abstract: A roller-switch and cam, located at an intermediary joint of a plural arm overhead assembly, delays the unlocking of a brake at a next adjacent joint until the joint at which the cam and switch are located has diverged a predetermined angle from alignment.

Abstract: An arrow rest, movable to clear fletching on an arrow released from a bow includes a pivotal arrow rest pivoting to an upright arrow holding position for drawing the bow, and lowered to arrow clearing position, having a triggering control attached to an end portion of the bow responsive to movement of the bow limb after arrow release for moving the arrow holding assembly from the upright position to the lowered position. The triggering control includes a controllable counterweight, for adjusting the timing of arrow holding release.

Abstract: A modulator valve control assembly which is attached to an automatic transmission in an automotive vehicle to operate the modulator valve of the transmission in response to movement of the throttle linkage. The modulator valve modulates the shift point at which the transmission changes from one mode to another. The assembly includes a rectangular housing in which a bell crank lever is rotatably supported with one arm engaging a plunger which, in turn, is slidably disposed in a connection means for engaging the modulator valve of an automatic transmission. The other arm of the bell crank is connected through a helically coiled spring to a flexible core element of a motion transmitting remote control assembly which includes a conduit or guide means for slidably supporting the core element. The other end of the core element is attached to a threaded rod which, in turn, may be attached to the throttle linkage.
