Abstract: A multi-function system for automatically filtering and maintaining cooking oil in fryer pots of a deep fryer having a deep fryer and a plurality of fryer pots is provided. Each of the plurality of fryer pots contains at least a first temperature sensor and a second temperature sensor. The deep fryer is capable of operating in an automatic filling mode to maintain an oil level when the first sensor senses a first predetermined oil temperature and an automatic filtration mode to allow filtration of oil in one of the plurality of fryer pots after the first sensor senses a first predetermined oil temperature.

Abstract: A frypot having a corrugated bottom portion. The corrugations project into an interior volume of the frypot, so that there are troughs disposed between the corrugations. During operation of the frypot, oil located in these troughs remains cooler, thus prolonging the life of the oil.

Abstract: An insect exterminating device which is characterized in a first embodiment by a handle having a handle base attached to a downwardly-extending probe frame fitted with a bracket and a spring for receiving an aerosol or pressurized fluid canister containing an insect treatment fluid. A probe projects from the probe frame and a spring-loaded activator button is provided on the handle base for activating the pressurized fluid canister valve to dispense the treatment fluid from the canister, through passages provided in the activator button, the handle base, the probe frame and the probe, into an insect bed. In a preferred embodiment the bracket is adjustable for accommodating pressurized fluid containers of various length. In a second embodiment the fluid canister is seated on a spring in a round frame and the treatment fluid is dispersed from the canister through a tube to the probe by pressing a spring-loaded activator button.

Abstract: A heart valve prothesis rotator which also has an annealed stainless steel shaft which can be bent by the surgeon interoperatively. The shaft will retain its shape after bending. Surrounding the shaft is a drive coil which connects a rotator head at a proximal end of the shaft to a drive knob at a distal end of the shaft and adjacent a handle. By turning the drive knob, a surgeon can turn the rotator head, thus orienting the prosthetic heart valve. Torsional motion is carried along the path defined by the bendable shaft so that the rotator head can be turned without displacing the handle of the heart valve rotator.
