Abstract: The invention relates to an image producing device having an ink-ribbon cartridge (22) which comprises an ink ribbon (42), two winding cores (100, 102), onto which the respective end portions of the ink ribbon (42) are wound, and a housing (98) which receives the ink ribbon (42) and the winding cores (100, 102). Said housing has two winding-core receiving parts (104, 106) for receiving the winding cores (100, 102) and an opening part (108) which is provided between the receiving parts (104, 106) and via which the middle region of the ink ribbon (42) is accessible. Furthermore, the device comprises a cartridge holding part (46) for inserting the removable cartridge (22). A planar or flat thermal print head (110) is arranged in an oblique position in the receiving part (46). It has a side face (120) and a heat producing part (122) for melting on the printing ink of the ink ribbon (42) resting against the side face (120). An impression cylinder (124), arranged in a position opposite the heat producing part (122) of the thermal print head (110), presses a paper sheet (P) against the thermal print head (110) in intimate contact with the ink ribbon (42). When the thermal print head (110) is actuated in this state, the printing ink of the ink ribbon (42) is melted on and transferred to the paper sheet (P). <IMAGE>

IPC: H04N5/232
Filed: 1989-03-03
Abstract: The invention relates to a still frame camera having a viewfinder device in which the object image projected onto an image plane by an objective (2) is scanned raster line by raster line by the sensor element row (22) of a CCD row array (21). For this purpose, the row array (21) is mounted on a slide (9) which is longitudinally displaceable by means of a spindle drive (12/13). As a viewfinder device, a mirror reflex device know per se is used. The movable mirror (16) is permanently arranged on the slide (9) in front of the row array (21) in the present case. In the starting position of the slide (9), the mirror (16) is located in the light path of the objective (2). During a scan, the slide (9) is moved in the direction of the arrow (P). During this movement, the mirror (16) moves out of the light path and the sensor element row (22) of the CCD array (21) moves into the image plane. <IMAGE>

Title: Activating full load enrichment in electronic fuel injection IC engine - producing full load enrichment if throttle valve opening angle is greater than specified angle dependent on IC engine RPM
Inventor: WEINGAERTNER REINER
IPC: F02D41/10
Filed: 1989-05-03
Abstract: With the operation of the IC engine, the rpm and the throttle valve opening angle are monitored  repeatedly.

With a larger throttle valve opening angle that the specified opening angle a full load enrichment results, with a smaller opening angle than the specified throttle valve opening, a control or regulation of the fuel injection amount is carried out without full load enrichment. A throttle valve position sensor (15) and a rpm sensor (18) are provided, the outputs of which are connected to a control unit (30) contg. a microcomputer (31). An EPROM storage (36) assigned to the comptuer stores the specified throttle valve opening angle as a function of the rpm also a programme for carrying out the method.

Title: Leak testing for vertical tank or tank colony - detecting pressure differences between point in liq. and point coupled to gas cushion via liq. at regular intervals
Inventor: HOEHNER ANDREAS
IPC: G01M3/32
Filed: 1989-08-30
Abstract: The liq. contents are determined at timed intervals. A display is activated if a max. permissible change in contents is exceeded. Pressure differences between a point in the liq. and a point connected to a gas cushion via the liq. in the tank are ascertained at regular intervals. Changes in the pressure differences are recorded and normalised taking into account the timed intervals. The method tests if the time normalised liq. mass charges attain the stipulated value normalised to the same intervals. If exceeded, a display is activated. The pressure difference measurer (3) supplies electrical measurement signals to an electrical signal processing assembly (9, 10, 11, 12) including an a-d converter (9). ADVANTAGE - At low technical cost, enables even small leaks to be detected including cases where the temp. of the tank contents changes during the test procedure.
Patent DE-3933716-A1 (DE)
IPC: F28B1/00
Filed: 1989-10-09
Abstract: The invention relates to a method and an apparatus for degassing plants which emit exhaust air containing organic compounds, in particular composting plants. To achieve the object of erecting plants with the same emission load as hitherto inside closed built-up areas, the odour-laden gases from the plant are fed via a pipeline (2) to an outlet point (3) remote from the plant and the temperature difference between the exhaust air emerging from the plant (1) and the pipeline (2) is used to remove water from the exhaust air. As a result, it is possible, on the one hand, to meet the legal requirements relating to the emission of decomposition exhaust air in an advantageous way and, on the other hand, plants having organic gas emissions, such as composting plants, and the infrastructure associated with them do not have to be erected in an otherwise still untouched region of nature. <IMAGE>

Patent DE-4006714-A1 (DE)
Inventor: PRICE HOWARD CHARLES
IPC: A61F2/38
Filed: 1990-03-03
Abstract: A plurality of polymer layers are stacked together and subjected to a consolidation operation to generate an orthopaedic bearing component (18). Each layer is formed by longitudinally extending polymer fibers that are placed or woven together to define a predetermined orientation of the fibers. The consolidation operation fuses the layers together while at the same time retaining the predetermined orientation of the fibres. The component may be a tibial bearing plate for a knee implant. The orientation of fibers parallel to the direction of sliding movement between the bearing plate (18) and the femoral component (12) of the implant is believed to reduce friction between the components. <IMAGE>

Title: Fine current source for high energising - has diode in parallel to base-emitter path of identical polarity transistor
Inventor: CLEMENS PETER
IPC: G05F3/22
Filed: 1990-04-18
Abstract: The current source is formed by a parallel connection of a diode (D1) with a base-emitter path of a transistor (T), with identical polarisation and considerably higher diode current. Thus high ohmic resistors are not needed for adjustment of small current source with high activation. A second diode (D2), and two resistors (R2,3) provide a biasing voltage and a temp. compensation. The current (I) remains stable. The resistors (R4 - 6) provide a voltage (U) division, but the control current flows across a resistor (R1). @(3pp Dwg.No.1/1)@

IPC: G01B11/06
Filed: 1990-05-19
Abstract: A process and a device are disclosed for monitoring and controlling an etching operation during which one or several layers having different reflection degrees applied on a substrate are selectively removed. In order to automatically detect the end of the etching operation, i.e. the removal of the layer during the etching operation, a light ray is projected during the etching operation onto the layer to be removed, the intensity of the reflected light ray, if necessary decomposed, is detected and evaluated, and the etching operation is interrupted (final point detection) when the progression in time of the total intensity curve, or at least of a component intensity curve, undergoes a characteristic change. The device has a white light lamp (4) linked to a light guide (6) having if necessary optical elements, another light guide (7) linked to a commercially available colour recognition device (8) capable of decomposing the reflected light, if necessary by means of filters, in spectral colour components, of detecting the total intensity as well as the component intensities, if necessary, and of transforming them in measurement signals, and a data processing system (3) provided with a measurement signal detector (2) that evaluates in real time the measurement signals and if necessary controls the whole etching operation.
