Patent DE-3838896-A1 (DE)
Title: Fuze/detonating element which can be initiated by laser and is provided with a storage layer
Inventor: BREDE UWE DIPL ING
IPC: F42B3/113
Filed: 1988-11-17
Abstract: By positioning a light-absorbent layer (3) in front of the explosive (4) in a fuze/detonating element which can be initiated by laser, the energy of a laser pulse is more effectively converted into a heat pulse, so that considerably less energy is sufficient for reliable detonation. The energy input into the light absorbent layer (3) can be further improved by roughening the inside of the inlet window (2). Q-switched laser pulses are converted by the light-absorbent layer (3) into heat pulses which are extended in time. It is possible to use especially metals, metal compounds and dyes for the absorbent layer. <IMAGE>

Patent DE-3843645-A1 (DE)
Title: Optical printer with a half-tone printing system
Inventor: ITO TETSUYA
IPC: H04N1/23
Filed: 1988-12-23
Abstract: In a printer which prints a half-tone image on a mobile, photosensitive component by means of image exposure, light is used which is emitted by a series of LEDs. The locked image data of a line quantity are transmitted to the respective LED elements within a time period determined for an exposure of an image line, a number of times which corresponds to a desired image density. The respective LED elements emit light in response to each emission of image data and together produce a corresponding electrostatic charge image on the photosensitive component. As a result, a brightness gradation of an image determined by the number of LED light emissions is obtained. <IMAGE>

Title: Hatch-cover support for a ship
Inventor: NISKANEN AULIS
IPC: B63B19/12
Filed: 1989-02-16
Abstract: A support for a cargo hatch cover (7) of a ship is described. The support is arranged between the hatch cover (7) and the margin of the hatch (13) and is attached to one of these parts. In this arrangement, the support serves to transmit forces from the hatch cover to the hull, the hatch cover and the hull move relative to one another in rough seas, and the support is provided with a guide (1) in the support frame (2, 4) to permit this movement. If the cargo hatch cover slips relative to the hull under a heavy load, the guiding or sliding surface of the guide must have a good coefficient of friction against the mating part. However, materials which meet this requirement are not strong enough to resist the non-uniformly distributed forces which result from the deflection of the cargo hatch cover. The invention solves this problem by the support being self-adjusting and being orientated at least at its guide side in the direction of the mating surface even if the hatch cover (7) is deflected. <IMAGE>

Title: Low loss inverter circuit with energy feedback capability - has thyristor switching, voltage and current limitation by wattless components and transformer feedback to source
Inventor: HOHMUTH GUENTER DIPL ING
IPC: H03K17/0814
Filed: 1989-05-10
Abstract: The inverter circuit has gate-controlled semiconductors (V1,V2) e.g. thyristors for each phase of the AC output circuit fed via a current limiting inductor (L1), with freewheel diodes (V3,V4).  Voltage rise limitation at switch off points is effected by capacitors (C1,C2) and diodes (V5,V6).  Auxiliary capacitors (C3,C4) minimise the effect of overswing during the charging of capacitors (C1,C2) and have large capacity. A gap-free or high permeability transformer (T1) provides efficient energy feedback to the DC source via polarising diode (V90). USE/ADVANTAGE - High power drives e.g. electric traction.  Energy efficient with low circuit loss and feedback capability.  Can be constructed as a two or three terminal network for single or multiphase applications. Handles higher voltage.  Current and frequency than previous installations due to limitation of voltage gradients and thermal loss.

Inventor: HELMBOLD JAMES EDWARD
IPC: G06K19/06
Filed: 1990-02-02
Abstract: A printer for serially printing bar codes on a web of record members has a thermal print head driven by a series of pulses having a constant duty cycle for each row of information printed. However, the number of pulses in the series is varied from row to row, in accordance with (a) the status of the current row being printed as a bar row of a space row; (b) the status of at least one row immediately preceding the current row and at least one row immediately succeeding the current row; and (c) the number of bar rows previously printed. By varying the number of pulses applied to the thermal print head and thus the amount of energy applied thereto, discontinuities in the serial bar code and any characters printed adjacent thereto are minimized. <IMAGE>
