A sample retention apparatus for use in a device for measuring hemostasis. The device for measuring hemostasis may include a sample articulation apparatus including a guide shaft coupled for articulating motion to a drive motor, a sample carrier secured to and axially moveable along the guide shaft between a sample ready position, a sample testing position and a sample ejection position. The sample carrier therefore articulates in unison with the articulating motion of the guide shaft. A measuring apparatus may include a sensing column. The sample retention apparatus may include a sample cup defining a volume within which a sample may be disposed. The sample cup may be adapted to be operably positioned within an aperture formed within the sample carrier. The sample testing apparatus may also include a sample pin that is engageable with the sensing column. The sample pin may include a tip portion for extending into the sample cup. The sample pin may also include a flange extending radially outwardly from the tip portion for substantially completely enclosing the sample space during measurement of hemostasis.

A method and apparatus are provided for measuring hemostasis. The apparatus includes a torque sensing column having a torque sensing element and a drive ring disposed around a body of the column and in registration with the column so as to allow rotation of the drive ring around a longitudinal axis of the column. The apparatus further includes a first guide shaft rigidly secured to the drive ring, the guide shaft extending parallel to the longitudinal axis of the column and a cup holder movably attached to the guide shaft, allowing the cup holder to move parallel to the longitudinal axis of the column. The apparatus also includes a sample cup adapted to engage the cup holder on a outer surface and the torque sensing element of the torque sensing column on an inner surface.

A gear indicator for a bicycle that includes first and second control cables connected to first and second shift actuators, respectively. The gear indicator includes a housing mounted onto the control cables. The housing is spaced apart from the shift actuators and is not attached to the handlebars. First and second pulleys are disposed in the housing and are rotatable by a displacement of the first and second control cables, respectively. First and second gear display elements are movable in response to the rotation of the first and second pulleys. The first and second display elements indicate the currently selected gears of the bicycle.

A system for treating teeth and associated tooth structure using a pressurized air propellant mixed with abrasive material includes a manifold which defines air passages leading from the pressurized air source to dispensing chambers which hold the abrasive material. The manifold further provides a convenient structure for mounting a number of the system components. The manifold simplifies assembly of the system and improves the integrity of air passages within the system. The air abrasion system also has a mixing block and continuous purge feature which eliminate crosstalk and backflow problems when switching between abrasive materials. Evacuation apparatus incorporating a cyclone separator is integrally provided with the system which requires minimal regular maintenance and maximizes suction flow through the apparatus. A boost feature of the system is provided to selectively increase the ratio of abrasive material to air in an air-abrasive material mixture, thereby increasing the rate of tooth reduction, without requiring additional air pressure.

The invention is a water lifter for use on knocked down multi-hull sailboats. The water lifter comprises a water bucket attached to one or more bucket lines which in turn are attached to one or more down pulleys. The down pulleys are in turn connected by pulley ropes to one or more top pulleys to provide sufficient mechanical advantage for a small single person to lift the water bucket out of the water. The top pulleys are attached to the uppermost hull of the knocked down multi-hull craft. On small sailboats, a single small person then braces his feet against the down hull, and positions his back against the water bucket, and pushes the water bucket as far as he or she can from the down hull, using his or her strong leg and back muscles. The weight of the water in the water bucket, as much as 400 pounds or more, combined with the now extended moment arm provide the necessary torque to lift the mast of the knocked down sailboat out of the water and rotate the sailboat so that it will come to rest upright on all of its hulls, in quick, easy, and very safe manner. For larger multi-hull sailboats, a boom arrangement with a winch affixed at the base of the mast assists in lifting a larger water bucket with more water, thus a greater weight, a greater distance from the down hull, thus overcoming the weight of the heavier mast, sails and hulls.
