A47C020/02

US Classification:

005/652000

Abstract:

Pillows for use by patients to help ease the pain in the thoracic, abdominal, pelvic, and flank areas originating from a variety of causes including for example, surgical incisions and stitches; internal and external injuries or bruises, such as bruised or fractured ribs; and natural body aches, such as menstrual cramps. The pillow is preferably made from resilient closed cell foam and has a handle to assist in placement of the pillow over a region of pain. The pillows can be washed and reused. Disposable or washable covers and heating or cooling packs can be used in conjunction with the pillows of the invention.

Abstract:

According to various aspects of embodiments of the invention, the actual flow rate produced by a metering pump is continuously measured using a positive displacement flow meter. Based on the flow rate reported by the meter, the output of the metering pump is continuously adjusted via a pump controller to achieve a desired set point flow rate. The operator sets a desired flow rate, rather than setting the pump cycle rate, or the output rating per pump cycle to produce an approximate output flow rate. According to some embodiments of aspects of the invention, a fluid feed system commanded to a fluid flow rate set point by a set point signal includes: a metering pump receiving a control signal directing a cycle rate for the metering pump; a fluid flow meter connected to measure a fluid flow rate produced by the metering pump and which provides a fluid flow rate signal; and a metering pump controller responsive to the set point signal and the fluid flow rate signal to adjust the control signal to direct a cycle rate which produces a fluid flow rate equal to the fluid flow rate set point. According to other embodiments of aspects of the invention, there is a method of controlling a fluid flow rate, comprising: displacing an approximately defined quantity of fluid at a rate determined by a control signal; measuring an actual flow rate; and adjusting the control signal to produce a rate of displacing the approximately defined quantity of fluid such that the actual flow rate matches a desired flow rate. According to yet other embodiments of aspects of the invention, a metering pump may be constructed and/or controlled as described above, in a chemical processing facility or a fluid dispenser. The variations described may be interchanged and combined in any suitable manner determined by one implementing an embodiment of the invention.

Abstract:

A novel salt of amiloride particularly amiloride citrate has been discovered. Because of its inherent insolubility and less bitter taste, it would lend itself to be more easily formulated into oral liquids, sustained release formulations and chewable tablets than would amiloride hydrochloride.
