Patent number: 7008276Abstract: A propulsion system which is designed to be used on a payload platform such as a spacecraft, satellite, aircraft or ocean vessel. To operate the system, electrical power is required. However, during operation the system does not require fuel or mass to be expelled into the environment in order to move in space. The system is designed to operate in two operational modes: in mode 1 the system incrementally moves the payload platform forward with each operational cycle. In the first mode, the system starts out with zero momentum and after moving a small distance is again left with zero momentum. In the mode 2 operation the payload platform accelerates forward a discrete increment of velocity during each operational cycle. In this second mode of operation these increments of velocity are additive.Type: GrantFiled: September 24, 2003Date of Patent: March 7, 2006Inventor: Virgil R. Laul

Publication number: 20020010437Abstract: Disclosed is a connector for introducing medication into a patient in a safe, convenient way. It comprises a pair of plastic tubular members adapted to be manually pushed together to engage in a male-female relationship, and a locking mechanism that detachably secures the members together. The male member has a sealed entry port at its end, and the female member safely houses within it a needle which centrally pierces the seal of the port upon engagement of the members. Preferably, the locking mechanism provides a “click” sound when it locks the members together.Type: ApplicationFiled: September 18, 2001Publication date: January 24, 2002Inventors: George A. Lopez, Virgil R. Laul

Patent number: 5309218Abstract: In a gas ring laser gyroscope characterized by a gain medium for producing at least one monochromatic narrow electromagnetic beam reflected to form a loop about the gain medium, the improvement wherein bypass channels are provided, displaced from the beam path, for reducing gas flow in the beam path. The bypass channels may extend about the gain medium and across the beam loop and may include controllable restrictions therein for selecting the flow rates therethrough.Type: GrantFiled: December 17, 1984Date of Patent: May 3, 1994Assignee: Northrop CorporationInventor: Virgil R.

Patent number: 4761548Abstract: An electric arc discharge switch having less susceptibility to electrode erosion and capable of being optically triggered. In a first embodiment the switch includes a gas tight body defining a hollow interior with electrodes mounted onto the body and forming a conducting path into the body interior. Portions of the body are optically transmissive to light frequencies above the photoelectric effect cutoff frequency for cesium vapor. A buffer gas and a predetermined quantity of vaporizable cesium are disposed within the hollow body interior and a flash lamp may be mounted onto the switch exterior. In operation, light frequencies above the photoelectric effect cutoff frequency for cesium are introduced into the switch body, ionizing the cesium vapor therein and reducing the resistance and breakdown voltage between the electrodes so as to initiate an electric arc. In an alternative embodiment a control plate with an aperture is disposed within the switch body between the electrodes.Type: GrantFiled: December 18, 1986Date of Patent: August 2, 1988Assignee: Northrop CorporationInventor: Virgil R. Laul

Patent number: 4757524Abstract: An improved X-ray tube including a coaxial tube with a center conductor isolated by a cylindrical insulator from a continuous annular interior conductor disposed about the insulator. The interior conductor includes sharp edged (high gradient) longitudinally aligned gaps in its surface with these gaps further generally aligned opposite one or more high atomic number targets deployed within the interior of a partially evacuated housing. A high voltage, high frequency AC or rapidly pulsed DC electrical excitation source is connected across the center and interior conductors to develop a high voltage electric field across the conductor gaps. A high voltage single or multiple pulse generating circuit is further connected across the interior conductor and the target to produce X-rays.Type: GrantFiled: March 19, 1986Date of Patent: July 12, 1988Assignee: Northrop CorporationInventor: Virgil R.

Patent number: 4337377Abstract: The present invention relates to a biologic apparatus that permits easy and quick telephonic transmission of biologic signals--such as an electrocardiogram, blood pressure, cranial waveforms, and the like--from any location having a telephone handset. The disclosed apparatus is so simple to use that, if necessary, an inexperienced person can perform the entire procedure.The disclosed apparatus comprises a single, small, lightweight unit that may be carried unobtrusively in a purse, a handbag, a brief case, an attache case, or the like; and may be put into use at any location having a telephone handset.It does not require cardiac-gel, and may therefore be used as often as necessary without causing skin problems. Furthermore, it obviates "hard-wiring" between the patient and the apparatus; so that there is no danger of pulling off electrodes.Type: GrantFiled: January 10, 1980Date of Patent: June 29, 1982Inventors: Wilbur E. Van Riper, Virgil R. Laul
