  • Patent number: 6428602
    Abstract: A method for recovering Pt from Pt-bearing coating on a gas turbine engine component. The component is contacted with a chemical stripping agent to dissolve away constituents of the coating and produce a Pt-bearing film of acid oxidation products at the surface of the component. The film is removed from the component to produce a Pt-rich residue containing at least about 10% Pt. The Pt-rich residue is collected and refined to recover Pt therefrom.

  • Patent number: 5663535
    Abstract: An apparatus for attenuating sound in a HVAC system has an inlet mouth aria a tube downstream of the inlet mouth. In the improvement, the inlet mouth defines a surface of revolution formed by rotating a segment of an ellipse about the long axis aria at a fixed distance therefrom. The new apparatus has an air flow transition chamber which permits air flow to "normalize" after air enters the apparatus at its inlet end but before such air enters the inlet mouth. The apparatus also has a baffle between the entry portion and the apparatus outlet end and positioned to occlude the enclosed cavity between the interior tube and the outer housing. The apparatus thereby more effectively attenuates sound in the third octave band. Optionally, the apparatus (either alone or in combination with a VAV terminal unit) has exterior insulation for preventing moisture condensation and further reducing objectionable sound.

  • Patent number: 5486140
    Abstract: The disclosure involves a variable air volume (VAV) terminal unit having an inlet collar, a box-like compartment connected to the collar and an insulation layer on the exterior surface of the compartment. The compartment is made of non-fibrous, rigid sheet-like material and an air stream flows through the compartment in contact with the sheet-like material and along a path spaced from the insulation layer. A method for making the variable air volume terminal unit involves steps including forming a plurality of flat, panel-like insulating components and securing a separate component to each of at least two compartment surfaces.

  • Patent number: 5383660
    Abstract: A football having a grip configuration which permits the thrower to easily reproduce his optimum hand location with every throw comprises a body with at least one elongated indentation on its surface. The indentation is intersected by a plurality of transverse bulkheads which divide the indentation into a plurality of finger pockets. In specific embodiments, more than four finger pockets are provided to permit an individual thrower to vary his grip location to that which best suits his throw.

  • Patent number: 5120357
    Abstract: The present invention comprises a process for improving the corrosion inhibiting properties of lecithin by heating a lecithin oil composition for a period of time sufficient to produce darkening of the lecithin. An optional step further improves the corrosion inhibiting properties of the composition by combining zinc oxide with the lecithin oil prior to heating.

  • Patent number: 5033216
    Abstract: A frame member for a sign assembly for use with flexible signs comprises an elongated body having an outer side having a front edge which defines a lip for engaging a back side of an edge portion of the sign and applying a tensile force to the sign. The channel extends longitudinally of the body and inwardly of the outer side thereof and opens in the outer side for receiving in edgewise fashion an elongated tensioning bar having an edge portion of the sign folded thereover and secured thereto by a plurality of spring clips. The channel is formed with a plurality of transversely spaced, inwardly facing shoulders which are engageable with the spring clips for securing the edge portion of the sign within the channel and enabling the sign to be tensioned by urging the tensioning bar inwardly of the channel to enable the material clamping means to successively engage successive shoulders.

  • Patent number: 4937961
    Abstract: A sign assembly has a frame surrounding an aperture, and a sheet of flexible sign material has a main portion stretched across the aperture and an end portion secured to the frame. The frame has a lip member defining the aperture, the lip member having a free end over which the flexible sign sheet passes, the frame also having a U-shaped channel portion rearwardly of the lip member and receiving an end portion of the sign sheet. A mounting bar extends longitudinally within the U-shaped channel, and the sheet end portion is wrapped, around the mounting bar. A series of spaced U-shaped resilient clips retain the mounting bar and wrapped around sheet end portion therein. The U-shaped channel has at least one wall with a plurality of longitudinally-extending shoulders which face in a rearward direction from the lip member.

  • Patent number: 4804898
    Abstract: A stock feed apparatus for feeding strips of stock to or from a stock processing machine to maintain a loop in the stock. The feed means is arranged to feed stock to or from the loop at speed correlative with the amplitude of a control voltage applied to the motor control. The stock loop sensor produces a first digital signal when the loop exceeds a first limit and a second digital signal when the loop exceeds a second limit. A loop control circuit is operative in response to the first digital signal to apply a control voltage of a first preselected amplitude to the motor control to drive the feed apparatus at a first speed until the loop moves away from the first limit and responsive to the second digital signal to apply a control voltage of a second preselected amplitude to drive the feed apparatus at a second speed until the loop moves away from the second limit.

  • Patent number: 4259547
    Abstract: A conventional hearing aid for a hard-of-hearing person has a microphone input for sensing sounds or voice communication. In a high noise environment, a somewhat remotely located speaker wishing to communicate with the person talks into a microphone input to a transmitter so that his spoken word is transmitted as a modulated carrier wave. The hard-of-hearing person is provided with a receiver which receives and detects the modulated carrier wave. The detected signal is applied to a transducer to reproduce the spoken word. A hollow elongated conduit comprising a flexible tube having a small bore extending therethrough, conducts the audible sound representing the spoken word from the transducer to the microphone input of the hearing aid, thus enabling the wearer of the hearing aid to hear the remotely spoken sounds of a lower level than the ambient noise while at the same time hearing the ambient noise. The conduit may contain a wire for acoustic loading and/or structural strength.

  • Patent number: 4057217
    Abstract: A butterfly valve includes a housing, a pivotal stem mounted on housing, and a disk mounted on the stem and tiltable within the housing to control the flow rate of a fluid. Means for attaching the stem to the disk includes a keyway defined by one of the stem and the disk, and an associated pin carried by the other of the stem and the disk. The keyway includes a ramp inclined with respect to the stem at a particular angle, and portions of the pin slide on the ramp in response to temperature change of the fluid to accommodate radial and axial displacement of the disk with respect to the stem. The particular angle of the ramp can be made dependent upon the diameter of the stem and the distance between a fixed point along the stem and the ramp pin. With this particular angle, the pin will slide on the ramp radially and axially of the stem while maintaining a fixed angular relationship between the stem and the disk.
