Abstract: A rotatable endoscope system having a rotatable insertion tube. The rotatable insertion tube enables the system to overcome egonomic deficiencies found in previous endoscope systems by allowing the user to move the view field without rotating the entire endoscope.

Abstract: An autoclavable endoscope suitable for attachment to a camera while hot. The structure of the endoscope adapted for attachment to the camera lens adapter presents a flat, co-planar proximal face, substantially devoid of grooves and crevices, and minimizes the space between the scope optics and the camera optics, thereby minimizing the volume of hot air that might be trapped between the endoscope and the camera.

Abstract: Formulations for topical or local administration of drugs directly to the breast or chest to produce a regional or local effect with lower systemic drug levels than when an effective amount is administered systemically are disclosed herein. In a preferred embodiment, the drug is administered to the surface of the breast, areola, or directly to the nipple. The formulations provide increased patient comfort, increased bioavailability and relatively high blood levels in the region to be treated with a reduction of side effects compared to those administered systemically. The preferred formulations contain drugs in the form of micro or nanoparticles, which may be formed of drug alone or in combination with an excipient or carrier. The excipient or carrier may modify the release rates or enhance absorption into the affected area. The drug formulation may be in the form of a cream, lotion or foam.

Abstract: A carton feeder for a continuous motion packaging machine utilizes a speed compensation mechanism implemented through a rotating valve assembly and actuation system. The rotating valve assembly provides a vacuum and compression to vacuum cups, for facilitating the transfer and release, respectively, of cartons within the carton feeder. The valve assembly includes a base plate and a rotating port plate. A circumferential position adjustment of the base plate advances or retards timing of the vacuum/compression to the vacuum cups within the carton feeder. A pneumatic cylinder assembly adjusts the circumferential position of the base plate. A speed sensor senses machine speed and sends a machine speed signal to a controller. The controller signals a solenoid responsive to machine speed to extend or retract the pneumatic cylinder assembly, thereby circumferentially adjusting the valve base to advance or retard vacuum timing.

Abstract: A carton feeder for a continuous motion packaging machine includes a speed compensation controller and a solenoid dual valve assembly, which enable the feeder to operate at higher speeds. The dual valve assembly includes a vacuum valve coupled to an air pressure valve which is controlled by an electronic controller. The speed compensation assembly is electronically connected to the valve controller, and includes an encoder driven by the feeder and a programmable limit switch for receiving data from the encoder and transmitting control signals to the valve controller. The method of operation includes detecting the position of the selector and transmitting position data to the limit switch. The limit switch calculates optimum valve actuation timing based upon both programmed information and data from the encoder, and transmits the control signals to the valve controller.
