Patent CA-2014553-A1 (CA)
IPC: F42B5/145
Filed: 1990-04-12
Abstract: What is described is a disintegrating igniter device for projectiles, grenades, cartridges, missiles and the like, consisting of a thin-walled aluminium sleeve, of a disintegrating ignition charge arranged in this, if appropriate of an ignition aid located in this charge, and of a flange piece arranged at the head end of the aluminium sleeve and having an axial bore, the aluminium sleeve being covered with a thin-walled plastic casing which is preferably produced from a shrinkable tube. Furthermore, there is preferably also a specially designed ignition aid which consists of ignition particles randomly distributed in the disintegrating igniter charge. Such a disintegrating igniter device is characterised by an especially clear-cut and reliable functioning, since its function pattern remains virtually unchanged even under the effects of a high load, such as occurs with the use of devices into which such disintegrating igniter devices are installed.

Abstract: MULTIBEAM OPTICAL AND ELECTROMAGNETIC HEMISPHERICAL/SPHERICAL SENSOR SYSTEM                 ABSTRACT OF THE DISCLOSURE    An optical spherical Luneburg lens is described which is also useful for millimeter wave and microwave operation, which cam provide a multitude of simultaneously acting receiving beams over a hemispherical or spherical field of view.   When used  in  conjunction with  surface mounted optical/radio frequency pickup elements, the lens can be employed in a passive target detection system of unique field of coverage and sensitivity.  The lens comprises a center sphere of refractive index of approximately ?2, around which are arranged in concentric shells of aerogel material.  The aerogel material of the respective shells is fabricated to obtain a particular  index of  refraction approximately equal to (2-(r/r0)2)1/2, where r is the radius of the shell and r0 is the radius of the lens assembly.  The lens can be employed  in a  system providing dual mode simultaneous optical and radio frequency operation with a single aperture.   Its multibeam simultaneous detection capability can provide an input to advanced digital signal processors to perform automatic image and pattern recogni-tion for commercial and military sensor systems.   It may also be used as an active sensor using optical or radio frequency energy.

Abstract: ABSTRACT OF THE DISCLOSURE          An apparatus and method which provides job integrity and security for each sheet transported to and from a printing station including periods when a printing machine has cycled down enabling an operator to remove sheets therefrom. Each sheet transported to the printing station and each sheet delivered from the printing station is counted. A controller compares the number of sheets transported to the printing station to the number of sheets delivered from the printing station and the number of any sheets that may have been removed by the operator from the printing machine as a result of a cycle down. Operation of the printing machine will be inhibited if the number of sheets transported to the printing station do not equal the number of sheets delivered from the printing station and the number of sheets removed by the operator. Conversely, operation of the printing machine will be enabled if the number of sheets transported to the printing station does equal the number of sheets delivered from the printing station and the number of sheets removed by the operator.
