Patent number: 5340056Abstract: An active defense system against ballistic missiles. The system includes a fleet consisting of a plurality of flying platforms fitted with interceptor missiles which loiter over hostile territory. The flying platforms communicate with each other by suitable data links and at least some of them also communicate with a ground station located in friendly territory.

Patent number: 5326049Abstract: A device, particularly a missile, includes a body having an appendage, e.g., a wing, normally folded in an inoperative position and to be unfolded to an operative position when the body is accelerated in the direction of the longitudinal axis of the body. The appendage is pivotally mounted about a first pivot axis extending perpendicularly to the longitudinal axis of the body, and also about a second pivot axis extending parallel to the longitudinal axis of the body. The center of gravity of the appendage is outwardly of the first pivot axis in the folded condition of the appendage such that the acceleration of the body produces a moment pivotting the appendage about the first pivot axis.Type: GrantFiled: January 11, 1993Date of Patent: July 5, 1994Assignee: State of Israel - Ministry of Defense Rafael-Armament Development AuthorityInventors: Hanan Rom, Oded Yehezkeli

Patent number: 5189913Abstract: An apparatus and method for determining the rate of rotation of a body rotating with an angular velocity .omega. about a first axis. The apparatus comprises a housing adapted to be fixed to the body so as to rotate with the angular velocity .omega. about the first axis and a mechanical system within the housing having more than two degrees of freedom. Electromagnetic drive coils are provided for applying a forced vibration to the mechanical system about a second axis substantially perpendicular to the first axis, thereby producing a Coriolis response along a third axis mutually perpendicular to the first and second axes, the forced vibration having a predetermined magnitude and a frequency which is constrained to lie within a predetermined range such that there is produced a coupling between the degrees of freedom whereby the magnitude of the Coriolis response is substantially insensitive to frequency.Type: GrantFiled: October 17, 1991Date of Patent: March 2, 1993Assignee: The State of Israel, Ministry of Defence, Rafael Armament Development AuthorityInventors: Ehud Netzer, Itzhak Porat

Patent number: 5142485Abstract: A new two-axis accelerometer comprising a rotating body linked to the motor rotor via a flexure zone. In a first type the rotating mass is concentrated and the flexure zone permits the rotating mass to perform a transversal parallel shift. In a second type the rotating body is an inertia rotor and the flexure zone is an extension of the rotor shaft that embodies a flexible portion. In either type the rotating body/flexure zone combination has two degrees of flexing freedom with two different flexure coefficients in two mutually perpendicular directions both normal to the electric motor shaft. The accelerometer further comprises a deflector shaft coaxial with the rotor shaft and extending beyond the rotating body and associated with electro-optical measuring means and processor means for measuring linear acceleration components in said two mutually perpendicular directions.Type: GrantFiled: July 16, 1990Date of Patent: August 25, 1992Assignee: The State of Israel, Ministry of Defence, Rafael Armament Development AuthorityInventors: Jehuda Rosenberg, Patrick Bar-Avi

Patent number: 5134725Abstract: A composite protective body suitable, among others, for making protective garments comprises a pliable flat case with at least one panel of soft ballistic material, and an insert within the case. The insert is composed of a plurality of consituent bodies of glass or ceramic material. The constituent bodies of the insert are of axisymmetrical or centrosymmetrical shape and of a size commensurate with that of the kinetic missiles against which protection is to be afforded. The bodies are arranged in at least two superimposed layers in each of which the constituent bodies are spaced from each other by a distance smaller than the size of a body with each body in one layer bridging a gap between two bodies of the adjacent layer. Each constituent body of the insert is glued to all surrounding bodies by thermoplastic or thermosetting material.Type: GrantFiled: April 11, 1991Date of Patent: August 4, 1992Assignees: The State of Israel, Ministry of Defence, Rafael Armament Development AuthorityInventors: Yehoshua Yeshurun, Dan Ziv

Patent number: 4703926Abstract: A sheet feeding apparatus includes an edge aligning device for aligning an edge of individually fed sheets with respect to an underlying table. A tray overlies the table and has an upper sheet-receiving surface for receiving the individually fed sheets. An aligning member mounted to overly the tray includes an aligning wall having a knife edge lightly engageable with the tray. The tray is reciprocated by a reciprocating drive through a forward stroke positioning the tray to receive a sheet on its sheet-receiving surface laterally of the knife edge, and a return stroke moving the sheet-receiving surface towards the knife edge to move the sheet thereon against the knife edge, thereby to align the sheet therewith, and then past the knife edge while further movement of the sheet is arrested by the knife edge, thereby permitting the sheet to drop onto the underlying table.Type: GrantFiled: August 6, 1986Date of Patent: November 3, 1987Assignee: State of Israel, Ministry of Defense, Rafael, Armament Development AuthorityInventors: Daniel Granot, Rami Servi, Ehud Armoza

Patent number: 4623893Abstract: A microstrip antenna comprises a first dielectric layer having a permittivity of 2.5-12.5 carrying the ground plane on one face and a feeder-resonator on the opposite face; a second dielectric layer thereover having a permittivity of 2.2-2.5 and carrying on its outer face a radiator electromagnetically coupled to the feeder-resonator; and spacing means spacing the second dielectric layer from the first a distance of up to seven times the thickness of the first, and providing a permittivity between the two dielectric layers which is approximately that of air. Matching of the antenna is obtained by varying the spacing between the two dielectric layers. The gain of the radiating element is better than 7.5 dbi for bandwidth of 15%. Sidelobe level is less than 15 dB in azimuth and elevation plan. The radiation pattern of the antenna is symmetric in both azimuth and elevation plan.Type: GrantFiled: December 6, 1983Date of Patent: November 18, 1986Assignee: State of Israel, Ministry of Defense, Rafael Armament & Development AuthorityInventor: Albert Sabban
