Abstract: An apparatus for detecting one or more contours of an image formed on a screen. The apparatus comprises a scanner for raster scanning pixels located on scan lines extending in parallel with each other in the X direction of a two-dimentional coordinate system to successively produce binary pixel data regarding the scanned pixels. The binary pixel data have a first value representing a background forming pixel or a second value representing an object forming pixel. The binary pixel data are transferred to a pixel data matrix forming circuit which thereby forms a pixel data matrix stored therein. The pixel data matrix includes pixel data regarding two adjacent pixels located on the next scan line. The latter two adjacent pixels are respectively adjacent to the former two adjacent pixels in the Y direction of the two-dimentional coordinate system. The apparatus also comprises a processing circuit which receives the pixel data matrix transferred thereto from the pixel data matrix forming circuit for producing data indicating the image contour(s).

Abstract: The invention relates to a device for the selective destruction or inactivation of cells, in which cells are illuminated successively with a light beam (61, 62) at a power which does not damage the cells. A detector unit (7) has at least one sensor (71, 72), which detects the radiation (78) reflected and/or scattered and/or emitted and/or transmitted on a specific cell as a result of the illumination and generates a detector signal (75, 76) if it registers a predetermined radiation or fluorescence. If a detector signal (75, 76) occurs, a further light beam (10) with a power and wavelength suitable for the destruction or inactivation of cells can be activated and can be projected through an optical system of a scanning arrangement (2) onto the specific cell, which is situated together with the cells in an imaging plane (21).

Abstract: The invention relates to a projectile (1, 101, 201) with adjustable control members (3, 9; 103, 131; 247) for influencing the trajectory of the projectile. The projectile has control electronics (13) for determining control signals for the adjustment of the control members, and an electrical generator (10, 110, 210) for the power supply of the control electronics. To simplify the construction of the projectile in terms of the adjustment of the control members and the power supply of the control electronics, it is proposed, according to the invention, that the electrical generator (10, 110, 210) be used additionally as an adjusting device for the control members. For this, there is a mechanical connection (3, 103, 246) between the moved part, generally the rotor (21, 121) of the electrical generator, and the control members (9, 131, 247) for the adjustment of these. Furthermore, the electrical generator (10, 110, 210) is connected to an electrical load (23, 24, 25) of which the size can be varied by the control electronics (13). The invention affords a small and effective construction for adjusting the control members, which can also be employed on small-calibre projectiles, for example grenades. …<IMAGE>…

Abstract: An optical head includes a reflection type grating lens for dividing specified polarized lights into a reflected light and a diffracted light, a device for detecting a RF signal from the reflected light of the grating lens, and a device for detecting focusing and tracking error signals from the diffracted light of the grating lens. The grating lens (23) consists of a plurality of domains having different optical properties respectively, so that the reflected and diffracted lights are obtained. The optical head further includes a total reflection prism (6) to compensate a phase difference between polarized lights orthogonal to a grating groove of the grating lens and parallel thereto, and a polarizing prism (24) for dividing the reflected light into two polarized lights orthogonal to each other in polarization thereof. Thus, a simple, miniaturized, and inexpensive optical head is obtained.

Abstract: A tool with two actuating handles (14, 15) is equipped with a locking mechanism which comprises a switch pawl (15') loaded by a spring (16) in the manner of a bistable rocker, in order to prevent not only a premature opening of the handles, but also their incomplete return which would allow premature closing.

When the switch pawl comes up against a fixed projection (17A), said first nose (15'E) comes into engagement with a second projection (18), or the switch pawl has two engagement members (151a, 151b) which are oriented mutually in reverse and which come alternately into and out of engagement with a row of teeth. <IMAGE>

Title: Safe and arm device for spinning munitions
Inventor: WEBB GEORGE
IPC: F42C15/26
Filed: 1988-11-08
Abstract: The invention relates to a safe and arm mechanism for an exploding projectile to be fired from a rifled gun. The projectile first experiences axial and angular accelera­tion which moves a setback ball (11) to initially arm the me­chanism. A third projectile parameter, angular velocity, functions to lock the ball in the armed position. During projectile flight, a spin actuated escapement mechanism moves toward a fully armed position, but may be precluded from reaching that fully armed position by a command arm arrangement. The projectile is then fully armed when a command arm signal releases the arrangement and the escape­ment mechanism is allowed to complete its motion to the fully armed position. When the projectile strikes a target, it experiences axial deceleration which moves a contact ball (17) partway to a detonating position. After the projectile passes through the target surface and into a void, e.g., into the hull of a ship, the deceleration ceases and the contact (17) ball moves under centrifugal force to a final posi­tion to detonate the projectile. 
     Movement of the setback ball (11) functions as one primary safety lock to preclude operation of the escape­ment mechanism. At rest, the ball (11) is positioned above a leaf spring. Axial and angular acceleration of the projec­tile depresses the spring (19) and the ball moves to another position. This motion releases the rotor (13) of the escapement mechanism. The rotor (13) is weighted so that rotation of the projectile causes it to tend to rotate. The cam follower of an electronically controlled actuator engages a cam track in the rotor and limits this rotation in stages from the fail safe position to an intermediate position where a command arming signal is required before the rotor (13) moves into the fully armed position. In the fully armed position, a contact ball (17) is brought into alignment with a switch   housing. 
     When the projectile strikes a target and dece­lerates, the contact (17) ball moves upwardly into an annular region and when that deceleration ceases and the projectile is in a void such as inside a ship's hull, the ball (17) moves rearwardly and outwardly in the annular area connecting a pair of contacts and detonating the device some distance beyond the point of impact.

Abstract: Plasticized polyvinyl butyral sheet option­ally containing a gradient color band is formed by continuously extruding a sheet having a predetermined region across its width formed from melt issuing from a die at an increased mass flow rate in comparison with other portions of the melt forming the rest of the sheet and then forwardly distorting such sheet immediately after forming by preferentially stretching the side containing the predetermined region to form an arcuate shape of substantially uniform thickness. Arcuately shaped sections are then cut from the sheet to form discrete, shaped interlayer blanks having improved thickness uniformity and dimensional stability providing improved performance when used in laminated safety glass.

Abstract: A device for generating a digitizing pulse for sampling an analog video signal includes a phase-­locked-loop (PLL) circuit and a phase offset circuit. The PLL circuit generates a correction pulse required to bring an output signal of digitizing pulses in phase with a reference horizontal sync signal. The phase offset circuit includes a digital memory which stores a digital number representative of a fraction of a pixel pulse that is desired as phase offset of the digitizing pulse. This fraction is converted into an offset current pulse having a duration equal to the duration of a pixel pulse and an amplitude that is the fraction of a maximum amplitude. The offset current is added to the PLL correction current for generating an output signal of digitizing pulses having the desired phase offset relative to the pixel pulses.
