Abstract: A light, self-contained, hand held, ultrasonic surgical scalpel having a housing, an ultrasonic power source within the housing, to which ultrasonic vibrations are provided to a blade to which result in cutting features by lateral motion as well as by reciprocating motion imparted to the blades with said cutting action being adjustable.

Abstract: A pressure swirl atomizer for providing a low-plume aerosolized spray of liquids, solutions or other suspension which includes a swirl chamber which create shear forces which causes the spray to aerosolize.

Abstract: A device for dispensing medication in an aerosol form from an MDI. The device is pre-loaded so as to automatically discharge the medication upon inhalation on the mouthpiece.

Abstract: A transient voltage surge suppressor is provided to protect equipment with voltage sensitive electronics, such as office equipment, from surges or transients in the multi-phase power distribution network furnishing power. The surge suppressor senses the incoming voltage and electrically disconnects its output to the office equipment if a voltage surge above an established level is sensed. The suppressor also disconnects its output when a ground connection in the multi-phase power network is disconnected to protect the equipment against excessive voltages. In this situation, the suppressor circuit protects its internal components from damage and possible fire hazard when its output is disabled, so that the suppressor can resume its function when conditions in the power distribution network return to a satisfactory state.

Abstract: A metered dose inhaler pump for delivering a metered dose of an active compound from an active compound inlet through a spray outlet without the need of a pressurized active compound container. Reciprocating action of an inlet valve, an outlet valve and a plunger alternately draw a metered dose of the active compound from an active compound container into an active compound chamber and pressurize the drawn metered dose of the active compound to eject the metered dose through the spray outlet. The plunger substantially fills and evacuates the metered dose chamber, leaving no void head space therein.

Abstract: A metered dose inhaler including a mechanism for agitating the medicament formulation prior to its separation in a measured dose, for administration to a mammal, including a human. The separated dose is a homogeneous mixture of prescribed medicine in a fluid carrier.

Abstract: An improved power filter circuit is disclosed. The improvement concern providing a clamping device between a ground lead and a terminal of a safety circuit such that when the power filter has its hot and neutral leads properly connected to hot and neutral leads of a utility circuit, a switch of the safety circuit connects the clamping device to be between ground and neutral leads of the power filter circuit, but when the hot and neutral leads of a utility circuit are reversed, the switch of the safety circuit connects the safety circuit directly between the neutral and hot leads of the power filter circuit, thereby creating an indicator, such as a red light, that the hot and neutral leads are reversed, yet the clamping device is now not connected between the neutral and ground leads of the power filter circuit. Accordingly, the clamping device connected between the ground and neutral leads may be rated during normal operations at a lower value, e.g.

Abstract: The disclosure is of a device for indicating the number of fluid dispensations remaining in a container for holding and dispensing metered quantities of the fluid. The device is a hermetically-sealed unit which is assembled with the dispenser portion or component of the container and includes microprocessor means for maintaining an inventory of the doses or dispensations remaining of a predetermined number of dispensations. Indicator means signals when the predetermined number of dispensations reaches a level before empty.

Abstract: A metered dose inhaler is described having an improved electronic counting means to indicate the doses remaining in the aerosol canister component of the inhaler assembly.

Abstract: A dipstick locator device is mounted inside the engine compartment of a motor vehicle, and more particularly to the dipstick assembly. The device includes a light source which is activated at least when the hood is lifted to enable a person to locate the dipstick even under poor lighting conditions.
