Abstract: An integrally-formed clip for releasably securing objects, comprising a clip body and at least one free arm attached at one end to the clip body. The free arm is positioned at an angle away from the clip body such as to create an opening between the second end of the free arm and the clip body. A latch is disposed on the second end of the free arm and has a free end extending toward the clip body at an angle. A tooth is disposed on the free end of the latch, positioned generally parallel to the free arm. There is at least one groove having dimensions substantially equal to those of the tooth arranged on the end of the clip body nearest the second end of the free arm. Downward pressure on the latch causes the tooth to be engaged by the groove and lock the second end of the free arm to the clip body. Upward pressure on the latch causes the tooth to become disengaged from the groove and release the second end of the free arm.

Abstract: This invention is directed to a frenum lock, also know as a natural expression former, for use by morticians. The improvement of this invention is the increased thickness of the central area or the medial area of the frenum lock and the decreased thickness of the peripheral areas, i.e., spaced end or wing area, of the frenum lock. As a result, there is more rigidity in the medial area of the subject frenum lock and more flexibility in the peripheral areas or wing ends of the frenum lock. This makes it easier for the mortician to insert and to position the frenum lock between the lips and the gums of the cadaver for the cadaver to have a natural appearance.

Abstract: A method for designing ultrasonic transducers used in diagnostic ultrasonic imagers, in particular, transducers made up of at least one piezoelectric layer and at least one acoustic matching layer, plus various bonding and backing layers. The method of transducer design uses a particular family of spectra as the basis of the bandpass characteristic. The approach is to specify a transfer function from the Transitional Butterworth Thompson family of spectra. The specification is influenced by trade-offs in bandwidth, transient response and design feasibility. This family is indexed by a design parameter called M. Using the M factor, a designer can more readily make the engineering trade-offs needed. By adjusting this parameter, any dynamic response from maximally flat to Gaussian can be obtained.

Abstract: An all-silicon monolithic capacitive absolute pressure-sensing device and method for making the same. The device employs a single-crystal silicon diaphragm that serves at a flexible capacitor plate of a variable capacitor. The diaphragm is bonded to a single-crystal silicon wafer to overlie a cavity etched into the wafer. A fixed capacitor plate of the variable capacitor is formed by a heavily-doped region at the bottom of the cavity. A thin dielectric layer is grown on the fixed capacitor plate to complete the capacitor. The cavity has a minimal depth such that the fixed capacitor plate provides overpressure protection for the diaphragm. At least a portion of the operating range of the pressure sensor occurs while the diaphragm is contacting the doped region. As a result, the capacitive output signal of the pressure sensor is produced by changes in contact area between the diaphragm and a thin dielectric situated on the doped region in response to pressure applied to the diaphragm.

Abstract: A method of fabricating a metal wood club head. The head is fabricated in two half-sections, each formed by a casting technique. Increased production throughput is achieved by the use of forming dies to maintain the shape of the two half-sections after removal from the casting molds, before the head half-section elements have fully hardened to a solid state. The two half-sections are subsequently joined by welding together facing edges of the respective half-sections along a parting line. The parting line extends through the highest point in the head crown, generally parallel to the face region and behind the hose. The placement of the parting line permits the use of simple one-piece mold cores, since there are no negative angles within the half-section elements to prevent such a core from being removed. The method is low cost, and provides a high strength club head, with the weld joint located away from club stress points.

Abstract: An adaptor (10) which allows a standard cartridge firing action to be used with a black powder muzzle loading gun (100) is described. The adaptor includes an insert (12) and a nipple (16) and is configured to be inserted into the barrel (108) of the gun adjacent the receiver (104). In use, a standard rifle cartridge casing (150) with a wall (150A) and with a head (150B) at one end containing a primer (152) is loaded into the receiver of the gun. Next, the cartridge casing is moved into the end (108A) of the barrel such that the casing extends into the center bore (14) of the insert and the nipple extends into the inside of the casing. When the gun is fired, the firing pin (114A) contacts the primer which ignites the black powder (118) which expels the projectile (120) from the gun. The ignition of the primer causes the wall of the casing of the cartridge to expand. The casing expands such that the casing is force fit and tightly held in the center bore of the insert.
