Patent number: 6235036Abstract: An animal ear tag applicator has first and second jaws moveable radially towards each other by a pair of pivotally connected handles. The jaws are biased to an open position and the first jaw with its male tag engaging pin is forced to move to an open position independently of the handles once the male ear tag has fully engaged with the animal's ear. The pin is angled forwardly so that with the radial movement of the first jaw the pin is at substantially 90° as the animal's ear is engaged and the pin is able to move beyond the 90° position before the first jaw opens. In one embodiment, the pin is pivoted on the first jaw to reduce the likelihood of the male and female tags jamming in the applicator.Type: GrantFiled: May 14, 1999Date of Patent: May 22, 2001Inventors: Michael Stuart Gardner, Roy Victor Bladen

Patent number: 6082926Abstract: A novel energy absorbing module is described which is relatively inexpensive, easy to make and provides for a relatively consistent crush resistance along its length when impacted axially. The module is made up of a generally cylindrical metal member which is formed from a roll of sheet metal that is wound into a tube having a spiral cross-section. A layer of spacer material, such as polyethylene foam, is placed adjacent the sheet metal so that the winds of the spiral are separated from one another. The energy absorbent module of the present invention provides a relatively constant and predictable level of crush resistance which makes it particularly suitable for such applications as an insert for a guardrail end treatment or other crash barrier. The module is formed by rolling a sheet of metal, or similar material, and the spacer sheet into a tubular or cylindrical form. A portion of one end of the module is then crushed slightly by impact loading.Type: GrantFiled: July 28, 1998Date of Patent: July 4, 2000Assignee: Texas A&M University SystemInventor: Richard A. Zimmer

Patent number: 4904942Abstract: A method of electroseismic prospecting is disclosed for detecting either the presence of two immiscible fluids present in a porous subterranean formation or the presence of a high-permeability rock formation including a substantially aqueous phase therein. A seismic impact produces an acoustical wavefront that results in an enhanced electromagnetic signal when it encounters either types of the above-described formations. This resulting enhanced electromagnetic signal is detectable as an indication of a likely hydrocarbon deposit, thereby giving additional data information with conventional seismic data to the geophysical prospector.Type: GrantFiled: December 21, 1988Date of Patent: February 27, 1990Assignee: Exxon Production Research CompanyInventor: Arthur H.

Patent number: 4353121Abstract: High resolution, high penetration marine seismic stratigraphic system wherein a slanted cable comprising spaced-apart hydrophone arrays gather seismic reflections so that the corresponding primary and ghost reflections from a common interface gradually are spaced apart. The primary reflections are time aligned and stacked. The ghost reflections are phase reversed, time shifted and time aligned to coincide with the time aligned primary stack and then stacked to give a combined primary and ghost stack, which effectively includes almost twice the information as from the primary stack alone. No inverse notch filters are needed to correct for the ghost phenomenon. Focused noise out of the vertical plane is also virtually eliminated.Type: GrantFiled: July 24, 1980Date of Patent: October 5, 1982Assignee: Fairfield Industries, Inc.Inventors: Clifford H. Ray, Neil A. Moore

Patent number: 4329627Abstract: A circuit for energizing a gaseous discharge lamp at high frequency utilizing a thyristor, preferably an SCR. The energizing circuit for the lamp includes a resonant or tank circuit operating at an appropriate high frequency, preferably above the acoustic resonant frequencies of the lamp, and which also commutates an SCR. The cathode/anode of the SCR is connected to a voltage adjusting network to provide an initiating pulse through the SCR to start oscillations in the resonant or tank circuit when the SCR is gated on and which reduces the applied supply potential to the SCR during its conduction period to ensure non-conductive latching of the SCR when the gate thereto is removed by lengthening the natural commutation interval of the SCR. This permits the SCR to be used as a switch at the high frequencies involved, normally about 60 kHz.Type: GrantFiled: May 8, 1980Date of Patent: May 11, 1982Assignee: Esquire, Inc.Inventor: Kenneth P. Holmes

Patent number: 4323956Abstract: An enclosure for a light fixture and the method for making such an enclosure via the securement of a plastic or glass lens, wherein the light fixture has a window which does not have to be opened in normal use for replacement of bulb, but is normally accessible through a rear or side opening. The window opening is circumscribed with a front flange projecting radially outward. A double sided adhesive tape is affixed to the flange and is united with the lens. A metal cored trim covers and secures the flange and the unified tape-and-lens structure. This latter assembly may be further secured by crimping.Type: GrantFiled: March 17, 1980Date of Patent: April 6, 1982Assignee: Esquire, Inc.Inventor: Marvin J. Pustka
