An insulated, water impermeable roofing system includes an array of factory assembled, laminar roofing panels self bonded to a roof deck. Each panel includes a water and vapor impermeable membrane and an insulation course coextensively overlying said membrane. The laminar roofing panels are mutually juxtaposed but laterally spaced from one another to provide a peripheral expansion zone which is filled with a water and vapor impermeable compound. The compound is plastic and self-adherent under no...

A remote control system for operating electrical loads, particularly in multi-unit lodging establishments such as hotels, motels and the like, includes a power sensing circuit for deenergizing the loads when the power supplied varies beyond predetermined limits in voltage or phase, a restart circuit for sequentially reenergizing the loads with the time between reenergization of loads on successive buses being dependent upon the period of time the loads were deenergized in order not to produce an...

This invention relates to a novel, non-progressive trifocal ophthalmic lens comprising distance-vision, near-vision and intermediate-vision optic fields. The non-progressive element of the trifocal lens is achieved by blending the transition zones between the different fields of vision. Further, unlike traditional trifocal lenses, the transition zones of the present invention are of uniform width, providing a smooth transition between the different optic fields that can not be easily discerned b...

The act of heating water within a contained vessel that is common to most buildings, whether residential or commercial or located in recreational vehicles, mobile homes, aircraft, ships or marine pleasure craft, causes calcium carbonate to precipitate out and settle to the bottom of a heating or fluid containing vessel. The use of ultrasonic transmission within the vessel will agitate the water held within, preventing the normally stagnant hot water from producing calcium carbonate. Other benefi...

A bag making machine sealer slitter apparatus for transversely sealing together and severing two layers of a tubular web of thermoplastic resin film, thereby forming a bag wherein the sealer slitter apparatus essentially comprising a sealing mans having two opposing seal bars equipped with heaters and a severing means including a retractable, superheated cutting edge.

A caster wheel which enhances critical shimmy velocity so as to minimize shimmy effects in operation. Two tread surface for contact with a ground surface and a pivot assembly for pivoting the wheel about a first vertical axis displaced from a second vertical axis extending through the center point of the wheel are provided such that the separation between the two tread surfaces strategically relate via a mathematical equation to said displacement in a manner for achieving a desired critical shim...

This invention relates to a universal medical forcep tool having a main body portion for receiving a replaceable grasping portion having grasping tips and respective support handles on which the tips are mounted. The main body portion forms a receptacle for receiving the replaceable grasping portions.

A shoulder arthroscopy abduction apparatus for use during a diagnostic and/or surgical procedure including a generally rectangular, homogeneous forearm sleeve member having two apertures located at one end. The first aperture receives a patient's thumb and the second aperture receives a patient's little finger. The forearm sleeve member releasably attaches to a generally U-shaped gripping and support member, having a pair of lateral support arms.

For the disposal of salt-containing dusts of incinerator plants, with addition of water the salt-containing dusts are intensively mixed with other waste materials, such as ashes and fly ashes from thermal power plants fired with hard coal or brown coal, waste materials from foundries containing quartz sands and waste materials from calcium carbide production, the mixture containing at least 8% hydrothermally reactive calcium oxide or equivalent amounts of other hydrothermally reactive calcium co...

The present invention relates to a receptor for a posterior pituitary hormone, oxytocin; a DNA sequence encoding for the receptor; a recombinant DNA molecule containing the DNA sequence and a transformant comprising the recombinant DNA molecule. The present invention further relates to methods of detection and diagnosis and a kit to aid in same which comprise either oxytocin, its receptor or antibodies to the receptor.
