  • Patent number: 5493306
    Abstract: A phased array antenna system capable of scanning at rates faster than the information rate of signals being received to prevent the loss of information during the scanning process. The phased array is configured to add the capability to provide moderate multi-dimensional separation of multiple signals and to eliminate the sensitivity loss due to sampling usually encountered with such rapid-scan systems. The array antenna system is comprised of the means to form multiple, time sequenced responses, each response corresponding to a different beam of sensitivity. The beams scan the full coverage sector and together with each other form a contiguous set of beams that both fill the coverage sector at any one time and also synchronously scan the full coverage sector. The beams are differentially delayed to permit the beam responses from any particular incident signal to be added in unison, giving rise to a compressed pulse whose time of occurrence is related to the signal angle of incidence.

  • Patent number: 5482745
    Abstract: A continuous spray coating apparatus and process generally comprises a housing defining a closed coating chamber, the coating chamber having inlet and outlet openings. Automatic doors are provided to cover the inlet and outlet openings, and the opening and closing of the doors is selectively controlled such that only one of the doors will be open at any one time during the spray coating operation. The introduction of the coating composition into the chamber creates a predetermined atmosphere within the chamber which is substantially saturated with constituents of the coating material, and by means of the automatic doors and control thereof, introduction of air from the outside atmosphere into the chamber is substantially prevented to maintain a predetermined atmosphere within the chamber.

  • Patent number: 5480964
    Abstract: A negative birefringent film, useful in liquid crystal displays, and a method for controlling the negative birefringence of a polyimide film is disclosed which allows the matching of an application to a targeted amount of birefringence by controlling the degree of in-plane orientation of the polyimide by the selection of functional groups within both the diamine and dianhydride segments of the polyimide which affect the polyimide backbone chain rigidity, linearity, and symmetry. The higher the rigidity, linearity and symmetry of the polyimide backbone, the larger the value of the negative birefringence of the polyimide film.

  • Patent number: 5457268
    Abstract: The invention relates to a process and a catalyst composition for the destruction of volatile organic compounds (VOCs). The process includes the step of contacting the VOCs with an oxygen-containing gas in the presence of a catalyst which is a metal-exchanged, metal-impregnated aluminosilicate zeolite with at least one exchanged metal in the zeolite being selected from the group consisting of Ti, V, Cr, Co, Ni, Cu, Fe, Mo, Mn, Pd, and Pt, and at least one impregnated metal in the zeolite being selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Mo, Pd and Pt, and wherein the difference between the exchanged metal and the impregnated metal varies the temperature necessary to promote oxidation of the compounds and for a contact time sufficient to oxidize the compounds. The process reaction temperature can vary from about 100.degree. C. to about 650.degree. C. and the contact time can vary from about 0.01 to 20 seconds. Preferredly, the reaction temperature is from about 150.degree. C.

  • Patent number: 5454993
    Abstract: An apparatus for immobilizing and positioning the lower or inferior portion of the human for radiographic examination or treatment. The device consists of a framework made from a base board, a plurality of siderails, a foot board and a pair of leg support blocks. A foam mixture is applied to the upper surface of the baseboard and to the leg support blocks and the entire device is placed into a large flexible container or bag. A patient's inferior or lower body portion is placed on the device in a supine position with a leg support block supporting at least one of the legs. The patient remains in a fixed position while the foam mixture expands around the patient's body and the apparatus framework. After a brief period of time, the foam sets or hardens and a mold or template is formed. This mold serves to immobilize the lower portion of the body during radiographic examinations and treatment as well as other procedures.

  • Patent number: 5454272
    Abstract: A non-destructive method for tensioning a cable under tension is described whereby the cable is contacted with an impact stimulus with a force transverse to the length of the cable thereby creating an incident vibrational wave in the cable and propagating the wave along the length of the cable. The propagating wave is sensed by a first accelerometer positioned on the cable which detects the passage and amplitude of the wave and creates electrical signals having a magnitude directly proportional to the amplitude of the wave. A second accelerometer which is positioned at a distance apart from the first accelerometer subsequently senses and detects the passage of the wave at the second accelerometer, also creating electrical signals having a magnitude directly proportional to the amplitude of the wave. The electrical signals from the accelerometers are received and processed to ultimately calculate the tension in the cable.

  • Patent number: 5452890
    Abstract: Golf club of the metal wood type and club head therefor. The golf club comprises a metallic club head having a shaft-receiving bore, and a metallic shaft which is inserted into the bore. An insert, which is less hard than the shaft, is inserted into the upper end of the bore for cushioning the shaft from fracture. A shoulder is formed in the bore for positioning this insert. The shoulder may be formed by a counterbore or by a tubular sleeve which is inserted into the bore. The shaft extends through the insert and into the bore of the club head. The insert, which is positioned between the shaft and the wall of the bore or counterbore, cushions the shaft from stresses which tend to cause fracture of the shaft at the point at which it enters the club head.

  • Patent number: 5446452
    Abstract: A temperature measuring system is described which is activated in response to the occurrence of detecting a temperature greater than a predefined critical temperature which includes a transceiver which receives an incoming electromagnetic wave, a temperature sensing means, e.g. a gas thermometer to measure the temperature of the desired component, and an electromagnetically interrogatable transponder chip capable of selectively transitioning from an inactive state to an active state upon the temperature exceeding the predefined critical temperature. The transponder chip when in the active state, converts the electromagnetic wave to a surface acoustic wave which passes over the transponder chip and upon exiting from the transponder chip is reconverted to an electromagnetic wave which is slightly modified from the incoming electromagnetic wave.

  • Patent number: 5439199
    Abstract: A valve selectively dispenses noncompressible fluid from a pressurized source into a receptacle. The valve has a body with a valve spool slidingly retained in a hollow cylinder in the body. The ends of the body are communicated by an internal channel, the first end adapted to engage the source and the second end adapted to engage the receptacle. The hollow cylinder is an intermediate part of the internal channel. The valve spool has first and second enlarged portions that effectively divide the hollow cylinder into first and second noncommunicated chambers. When the valve spool is in a closed position, the first end is communicated only with the first chamber and the pressure of the fluid in the first chamber provides an outward biasing force on the valve spool, keeping it in the closed position.
