A marker insertion apparatus automatically removes a marker from a roll of marker material and applies the marker to an applicator. The markers mount to a backing sheet and are peeled from the sheet by passing over a peel bar. Jaws are positioned near the peel bar and configured for gripping an end marker. An applicator member inserts intermediate the jaws and has the end marker pressed onto the applicator and torn from the roll. In a first embodiment, the applicator is a paddle applicator for inserting markers between opposing pages, and in a second embodiment the applicator is a bayonet applicator for inserting markers into the spine of a book.

Method for inserting markers into books

A book marker insertion apparatus includes a cartridge assembly, a separator assembly, a gripper assembly, an elevator assembly and a page spreader assembly. The cartridge assembly holds a roll of marker materials including a plurality of markers on a backing sheet and advances the material to the separator assembly. The separator assembly includes jaws and a peel bar for removing the endmost marker from the backing sheet. The gripper assembly includes rotatable arms which grip the separated end marker and position the separated end marker for insertion into the book. The elevator raises and lowers the gripper assembly from the position for gripping the separated end marker to the position for inserting into the book. The page spreader assembly includes a V-arm with a slot formed therein for receiving the gripper arms and the separated end marker.

A primary regulator having a zero-crossing detector and a voltage reference coupled to a processor is provided. The processor controls the on time of a primary transformer via a switching device isolated from the processor via a coupler A method of regulating a power supply to maintain a desired output voltage at a load including the steps of measuring an average output voltage at a load and controlling the on time of a switching device serially connected to a primary transformer input based on the measured output voltage and a zero-crossing signal.

An irrigation system and method for providing fluid from a source of irrigating fluid to a surgical site, in particular a surgical site access to which is provided by a small incision or a natural orifice of the body. The irrigation system includes a control unit that is used with a cassette. The control unit includes a motor under the control of a controller, a sensor for sensing the flow of fluid in the cassette, a sensor for sensing pressure in the cassette, and a user control panel. The cassette includes a fluid flow passageway having an inlet connected to the source of irrigating fluid and an outlet for providing fluid to the surgical site. A pump located in the cassette is driven by the motor. The pump has limited efficiency when presented with back pressure to thereby limit to a safe level an amount of pressure that can be delivered to the surgical site. The system may be used to irrigate or distend a surgical site.
