An improved oil preheater assembly for a waste oil burner that significantly reduces the labor time required to perform routine maintenance. This is accomplished by incorporating a removable cover to directly access the heated oil passages for cleaning thereby providing a simplified method of access to the areas most often requiring routine maintenance. Additionally this design provides an improved electrical control system which significantly reduces electrical energy consumption and the formation of oil carbonization when oil burner heat output is not required. Additionally this design incorporates a nozzle cleaning system for a low pressure siphoning type of discharge nozzle which can remove carbonization and other nozzle contamination and obstructions without the disassembly of components.

An endoscopic surgical rotary capture instrument is used in minimally invasive laparoscopic surgery for closing a gastric band having a buckle end a free end. The rotary capture instrument includes a pusher end that has a stationary jaw and a movable jaw. The movable jaw is actuated by rotary motion of an inner shaft. The jaws are used to gasp securely and push the tube end of the gastric band after it has been threaded through the buckle end of the band. A hook instrument is used to hold the buckle end securely while the rotary capture instrument is used to push the free end of the gastric band.

An access device adapted and configured to be inserted through a natural biological orifice, and related surgical methods are provided. The access device includes a body, a nozzle means and means for delivering a pressurized flow of fluid to the nozzle means. The body is configured and dimensioned to be inserted through a natural bodily orifice and has proximal and distal end portions and defines at least one lumen therethrough to accommodate passage of one or more surgical instruments. The nozzle means is operatively associated with the body for directing pressurized fluid into the lumen to develop a pressure differential in an area within a region within the lumen to form a fluid seal around the one or more surgical instruments passing therethrough.

A label cutting and applying apparatus is arranged to produce printed labels from a continuing strip of label material. By operation of a standard roller, the apparatus advances a strip of the material along a path from a roll of the material over a print head where a portion of the strip is printed. The printed portion is advanced past a cutting blade which is integrally formed with a vertically movable label applicator and is severed from the remainder of the strip by operation of the blade as the applicator moves downwardly. The label applicator can include a vacuum head which then blows the severed label onto a package to apply the label thereto.

An electronic tachometer utilizes a transducer, typically an optical encoder disc, connected to a movable mechanical element. The transducer produces a pair of triangular waves of fixed relative phase, each having slopes proportional to the velocity of the mechanical element. The triangular waves are differentiated and the resultant signals are sampled by gating pulses derived from the triangular waves themselves. The samples are combined to produce an output signal having a magnitude proportional to element speed and a polarity indicative of direction. In a combined system in which the transducer is attached to the shaft of a brushless motor, another output of the same transducer is used for commutation control of the motor stator windings. This arrangement is particularly useful in a velocity servo system, in which the tachometer output is compared with a signal indicating desired motor velocity. The comparator output is used to modify the commutation control so as to produce the desired motor velocity. Position encoding also may be accomplished using the same transducer.
