Abstract: A fluid containment pouch is provided that includes a first layer of material having a first thermal characteristic and a second layer of material having a second thermal characteristic. The first layer of material is thermally compatible with a patient covering upon which it is to be thermally bonded. Thermal bonds between the fluid containment pouch and the patient covering form fluid containment channels that retain expelled body fluids during a patient's operation to help maintain a sterile operating environment.

Abstract: A projector lamp for a vehicle headlamp and method for continuously forming the same, which lamp is formed from one piece of sheet metal and includes a cylindrical lens holder and a cup shaped reflector for reflecting light from a vehicle bulb toward the cylindrical lens holder. Integral tabs formed from and extending inwardly from the cylindrical lens holder secure an optical lens within the cylindrical lens holder.

Abstract: A device for the collection and testing of a fluid specimen is disclosed and claimed. The invention is particularly useful for collecting and testing human urine specimens but may also be employed in the veterinary environment or any time a potentially hazardous fluid is to be collected and tested and isolation of the specimen from testing personnel is desired. The invention keeps the specimen enclosed and sealed during transport and testing to facilitate safe handling of specimen. Some embodiments of the invention are highly resistent to tampering by the patient or during transport.

Abstract: An arthroscopy drape is provided that has an open top collection pouch connected therewith. The pouch is connected adjacent to a fenestration or opening in the drape through which a patient's limb will extend for an arthroscopy procedure. Connection of the collection pouch to the drapery panel is provided over a relatively small area whereby articulation of the joint on which the procedure is being performed will have little if any effect on the position of the drapery panel relative to the patient and operating equipment covered thereby, thus maintaining the sterile condition of the operating room.

Abstract: A sterilizable drape for draping an ultrasound probe during an invasive ultrasonographic procedure, and a process of forming such a drape. An elongated sleeve member, having an open first end and a substantially closed second end with a circular fenestration therethrough, is formed of a sterilizable, flexible, fluid impervious material such as polyethylene. A pair of pull ties extend from the open end to aid in pulling the drape over an ultrasound probe and cable. A tubular member, having an outside diameter substantially equal to the fenestration diameter and formed of a sterilizable, flexible, resilient, fluid impervious material such as latex, is sealed to the sleeve member and extends through the fenestration. The tubular member has an open first end, communicating with the sleeve member interior through the fenestration, and a closed second end.

Abstract: A drain plug for sealing the waste and overflow drain assemblies during construction and system testing. A threaded bolt extends through a rubber washer. The bolt is screwed into a tapped hole in the shoe assembly of the drain, providing a secure plug that will not blow out during system testing. A sleeve may be employed on the bolt to allow ease of access to the bolt when deep drains are plugged.

Abstract: An extractor for removing a ferrule which has been tightly press fitted onto a pipe. The extractor utilizes a frame within which is to be located the ferrule portion of the pipe. Within the frame, the ferrule is fixed in position with the open end of the pipe connecting with a plug. The plug is swivelly mounted onto a threaded rod. The threaded rod is threadably secured to the frame. Movement of the threaded rod causes movement of the plug against the open end of the pipe causing removing of the ferrule from the pipe.

Abstract: A hand-held ultrasonic tooth-cleaning apparatus which may be inserted into the mouth to remove materials from the teeth by cavitation using a lip seal or a continuous liquid flow. Electromechanical transducer elements are used to establish propagation of ultrasonic energy in a transverse mode with respect to the longitudinal axis of a vibrating member one terminus of which constitutes the probe which is inserted into the mouth by the user.

Abstract: An irrigation and drainage system for cultivated fields, croplands and the like for supplying and extracting water and similar liquids through a subsurface conduit network automatically responsive to the ground water table occurring above or below a predetermined subsurface reference level near the depth of the conduit network. A plurality of elongated subsurface perforated conduit lines are located throughout the field at a uniform depth below ground along one or more ground elevation contour line or lines for outflow or inflow of water through the conduit line perforations when the ground water level is respectively below and above the predetermined subsurface reference level. Distribution boxes having an adjustable weir and supply water and excess water connections are provided for the conduit lines at each elevation.

Abstract: An ultrasonic method and apparatus for removing dental plaque from teeth in situ and for cleaning the teeth employing a liquid couple for imparting ultrasonic energy to the surface of the teeth at ultrasonic energy levels which are not harmful to the teeth or gums.

Abstract: A unique "compass" device for drawing and measuring circles, and employing a template with a center pin and many holes. Indicia are provided on the template to indicate concentric and generally annular zones centered at a certain center, each such zone having its boundary relatively adjacent the center located a first distance from the center (on the particular distance scale employed on the compass), and also having its boundary relatively remote from the center located a second and higher distance from the center on such distance scale. The holes lie along an Archimedes spiral centered at the center, and all holes located a first perdetermined fraction of each whole number (of the particular distance scale) are disposed along one radial line extending from the center; all the holes located a second and next-higher predetermined fraction of each whole number of the particular distance scale are disposed along a second radial line, etc.

Abstract: Distance measurement by conventional optical interferometry requires physical movement of an optical element. The present system obtains interference with a continuous range of radiation wavelengths, providing a direct measurement of a constant optical path difference, in terms of the fringe count and the end wavelengths of the range employed. Variations in the optical path difference occurring during the measurement are compensated by simultaneous interferometry with a fixed wavelength.
