Title: Projectile impact fuze containing de-arming device
Inventor: APOTHELOZ ROBERT
IPC: F42C15/44
Filed: 1986-12-09
Granted: 1991-08-06
Abstract: INVENTION:  PROJECTILE IMPACT FUZE CONTAINING DE-ARMING DEVICE                      ABSTRACT OF THE DISCLOSURE     It happens time and again that a fuze does not function and that the projectile remains in the field or the place where it landed as a dud.  When such a dud is found the danger exists that it might explode upon the finder's touch or when moved or lifted.  To prevent this danger the impact fuze in a dud should be able to de-arm itself in a non-explosive manner.  This is achieved by positioning a dud insert or de-arming device between an explosive or firing train and a booster charge.   This  dud de-arming device contains  an escapement device which after a predetermined delay time following impact of the projectile moves a rotor from its armed or live position into its de-armed or inert position.  The dud de-arming device contains structure which, by virtue of the impact delay or deceleration, that is a delay in ignition of the booster charge upon the projectile hitting the target or ground, activates the escapement mechanism.

Title: Extended sar imaging capability for ship classification
Inventor: BOLES SOL
IPC: G01S13/90
Filed: 1987-03-11
Granted: 1990-05-15
Abstract: ABSTRACT Capability is provided using coherent synthetic aperture radar (SAR) techniques for substantially extending the useful range for producing 3 scaled high resolution orthogonal image projections on a CRT of a translating ship under the influence of rotational motions arising from sea state conditions, for the purpose of ship classification and weapon delivery from an airborne platform at long stand-off ranges. This advantage is brought about by determining image coordinates on the basis of range, doppler, and doppler rate measurements of individual scatterers and from ship angular rotational velocities derived from a weighted multivariate regression solution to doppler processed interferometric azimuth and elevation angle measurements of all significant ship target scatterers. In this manner, the image degradation suffered by plotting angular measurements directly, whose location accuracies are known to deteriorate rapidly with increased range due to high signal-to-noise requirements, is circumverted.

Granted: 1992-02-18
Abstract: ABSTRACT OF THE DISCLOSURE    An axial flow combine harvester feed plate for directing crop material from a conveyor into the lower forward portion of an axial flow rotor housing.  The feed plate includes surfaces that reduce the overall width of a mat of crop material entering the rotor housing and a surface that guides material upwardly and rearwardly.          The surface of the feed plate that guides crop material upwardly and rearwardly directs the mat of crop material into the rotor housing near the front of the axial flow rotor on one side of the rotor housing.  On the other side of the rotor housing, crop material enters the housing some distance rearwardly from the front of the axial flow rotor.  This results in a band of crop material engaging the rotor in the rotor housing.

Abstract: Abstract of the Disclosure A  television  (TV)  signal  receiving  apparatus displays  a TV signal  of a high definition system using a TV receiver of an NTSC system with the high picture quality of the high definition system.  An A/D converter converts an analog TV signal of a high definition  system to  a digital  signal.

The ratio of horizontal scanning lines of  the  high  definition  TV  signal  to  horizontal scanning lines of the NTSC TV signal is 5 to 7.  The horizontal  scanning  lines  are  divided  into  three portions in the vertical direction and four portions in the scanning direction and are supplied to twelve CRTs (monitors).  The CRTs are arranged in three rows and four columns to form a-picture plane.

Title: Frequency independent information transmission system
Inventor: HO KIT-FUN
IPC: H04L27/10
Filed: 1989-02-27
Granted: 1993-06-22
Abstract: ABSTRACT OF THE DISCLOSURE The system is used for transmitting information wherein each possible message unit in a set, (e.g. the alpha-numeric symbol set) is defined by a specific interval (I = f5/fR) and messages are transmitted by conversion to the interval code and for the sending of signals of any two frequencies (f5 and fR) that are related by the specific intervals. The signals are received by a receiver which computes the interval, matches it with the pre-defined message unit interval and outputs that message unit.  A sequence of message units may be sent using a reference frequency signal and a succession of specific signals each related to the reference frequency by the specific interval for that message unit.   A computer program can be utilized for automatically encoding or decoding.   The system has the advantages that is relatively free of errors caused by long term frequency shifting, allows  transmission at  any  frequency  level,  and  allows interacting   communication  between   stations  wherein  the transmitters operate in entirely different frequency domains. In particular, the system is operable to transmit information in the form of interval-coded tones suitable for interpretation by a human listener.  Examples of the use of the system include a clock and a voltmeter comprising tone output circuitry.
