Patent number: 7530640Abstract: A chair having a base, a seat support mounted on the base, and a seat back support coupled with the seat support. The chair further includes a seat support assembly coupled with the seat support and a back support assembly coupled with the back support. The seat support assembly is a multi layered piece having a base layer, an intermediate layer, a gel pad, a tail pad, and a top layer. Once assembled the seat support assembly has a relief area that corresponds to the tail bone region of the user. The back support assembly is multi layered piece having a base layer, an intermediate layer, a support pad assembly, and a top layer. The ordering of the layers and the orientation of the support pad assembly provide support to the user without any direct or focalized pressure being distributed to specific regions of the body.Type: GrantFiled: April 7, 2006Date of Patent: May 12, 2009Assignee: L & P Property Management CompanyInventors: Joseph Lawrence Walters, Jesse Love, James Arlin Riegsecker

Patent number: 7318667Abstract: A platform shaker for use in a CO2 rich environment that has a corrosion resistant output shaft and a corrosion resistant, sealed motor casing. An eccentric drive assembly is connected between the output shaft and a platform and has components treated with a corrosion inhibiting coating. A shaker control controls the electric motor has components treated with a conformal coating.Type: GrantFiled: March 22, 2005Date of Patent: January 15, 2008Assignee: Lab-Line Instruments, Inc.Inventors: Lawrence Walter Stalec, Bradley William Stone

Publication number: 20050189313Abstract: The present invention is directed to an improved container closure or lever cap comprising one or more of the following features: (i) an improved interface on the interior surface of the closure that consists of strategically positioned locking lugs to securely affix the closure onto a container, (ii) a repositioned lever handle and fulcrum to optimize function and mechanical advantage, (iii) a retro-fit sleeve for an incompatible container, which on the inner surface is fashioned to interface with twist necks bottles, or other closure designs and mechanisms incompatible with the interior fitting of the lever cap, and which on the exterior is fashioned to receive the interior fitting of the lever cap, (iv) a tamper-evident safety indicator, (v) a specialized vertical sloping sidewall at the container's distal end near the opening to improve the closure's vertical lift during operation, (vi) a child safety design and mechanism that requires two functions to unlock the lever and position it for normal operationType: ApplicationFiled: February 3, 2005Publication date: September 1, 2005Inventor: Lawrence Walters

Patent number: 6454112Abstract: A cargo container includes two tine tunnels disposed at the top of the container, for receiving the tines of a fork-lift truck. The tine tunnels fit between upper and lower header extrusions and a protection plate is provided to protect the container from the fork tines. Lifting the container at the top, rather than at the bottom, improves loading stability and minimizes container damage.Type: GrantFiled: April 20, 2000Date of Patent: September 24, 2002Assignee: Air Cargo Equipment (UK) LimitedInventors: Graham John Lawrence Walters, Mark Steven Ford

Patent number: 6070065Abstract: A satellite-based cellular communication system (100) is used to provide emergency services to subscriber units located anywhere on the earth. The surface of the earth is divided into defined areas and emergency codes are assigned to each one of the defined areas. As subscriber units (150) move relative to the surface of the earth, the satellite-based cellular communication system (100) updates the emergency codes stored in the subscriber units (150) as required based on the subscriber unit's current location. The subscriber unit (150) uses the stored emergency codes to determine when a user is requesting emergency services and prioritizes the call accordingly.Type: GrantFiled: January 9, 1997Date of Patent: May 30, 2000Assignee: Motorola, Inc.Inventors: Peter Joseph Armbruster, Kenneth Lee Sowles, Lawrence Walter White

Patent number: 5682763Abstract: A method for producing ultra high purity liquid oxygen from standard grade liquid oxygen which integrates the oxygen purification process with a nitrogen purification process by utilizing the condensing duty of liquid nitrogen, thereby causing the nitrogen to vaporize which is desirable prior to delivery to a nitrogen purification unit. The method of the present invention includes pressurizing a source of liquid nitrogen and vaporizing at least a portion of the pressurized liquid nitrogen. The resulting high pressure gaseous nitrogen stream is introduced to at least one bottom reboiler/condenser of a high purity liquid oxygen unit, which also purifies standard grade liquid oxygen into ultra high purity liquid oxygen. The gaseous nitrogen provides the needed heat to the distillation columns of the high purity liquid oxygen unit.Type: GrantFiled: October 25, 1996Date of Patent: November 4, 1997Assignee: Air Products and Chemicals, Inc.Inventors: Rakesh Agrawal, Zbigniew Tadeusz Fidkowski, Lawrence Walter Pruneski

Patent number: 4830976Abstract: An integrated circuit comprises a resistor that is formed by doping a semiconductor region that is defined by a layer, typically polysilicon, that also defines the gate electrode of field effect transistors in the integrated circuit. The well-controlled linewidth of features defined in this layer provides for tight resistor tolerance, and also allows the value of the resistor to track changes in other features defined by this layer.Type: GrantFiled: February 24, 1987Date of Patent: May 16, 1989Assignee: American Telephone and Telegraph Company, AT&T Bell LaboratoriesInventors: Bernard L. Morris, Jeffrey J. Nagy, Lawrence A. Walter

Patent number: 4645948Abstract: A field effect transistor circuit generates a reference current that can obtain a desired temperature coefficient. The circuit is self-compensatory with respect to process variations, in that a "slow" process will produce a higher than normal current, while a "fast" process will give a lower one. This results in a tight spread of slew-rate, gain, gain-bandwidth, etc. in opamps, comparators, and other linear circuits. A simple adjustment in the circuit allows the temperature coefficient to be made positive or negative if so desired. An illustrative circuit is shown for CMOS technology, but can be applied to other field effect technologies.Type: GrantFiled: October 1, 1984Date of Patent: February 24, 1987Assignee: AT&T Bell LaboratoriesInventors: Bernard L. Morris, Jeffrey J. Nagy, Lawrence A. Walter

Patent number: 4084159Abstract: An antenna tracking system in which attenuation of gain in the azimuth tracking circuit as a function of the angle of elevation of the antenna is compensated. A correction circuit is provided in the servo loop for amplifying the azimuth error signal and rate gyro signal by an amount equal to the secant of the elevation angle.Type: GrantFiled: September 2, 1976Date of Patent: April 11, 1978Assignee: Sperry Rand CorporationInventors: Wilbert Cleon Anderson, Vernal Wynn Thompson, Lawrence Walter Urry
