Patent DE-19712419-A1 (DE)
Title: Film cartridge with visible exposure indicator
Inventor: HARRIS CLARK EUGENE
IPC: G03B17/30
Filed: 1997-03-25
Abstract: The cartridge (10) incorporates a rotary spool (18) and an annular indicator wheel (48) turning behind a window (38), to indicate the state of exposure (54). As the wheel turns with the spool, successive sections of it are deflected by a protrusion (78) towards the window, positioning the indication in it. The indication (54) can be on one side of the wheel and a driving dog on the other and near the indication. The dog is engaged by a mating one (62) on an annular driving wheel (40), and the protrusion lifts the first dog free while the indication is positioned in the window. The indication can include an indicator block (52) preventing further rotation of the wheel while in the window.

Patent DE-19714745-A1 (DE)
Inventor: WEBER JOHANNES
IPC: B61F5/14
Filed: 1997-04-09
Abstract: The system has two or more vibration-dampers connected in parallel, being particularly for a rail-vehicle bogie. Each damper has a fluid-filled working cylinder and a piston with rod, and is connected hydraulically to a damper on the other side of the bogie length with axis. The hydraulic connections (1) are such that on parallel vibration in the bogie frame (3) a pressure-less exchange of damping fluid takes place between the working chambers (4) of the dampers. When vibration is torsional, the compressing damper working chambers are connected together, as are the expanding ones. The dampers (2) can be in diametrally opposite positions, the piston rod (5) of one being coupled to the vehicle body (6) on an axis parallel to the bogie slewing axis (7). The cylinder breech end (9) is coupled to the bogie frame at the end furthest from the slewing axis. The hydraulic connections (1) run between the chambers (4a) at the piston-rod ends and between those (4b) at the breech-ends of the dampers.

Title: Diagnosing functioning states of catalytic converter
Inventor: YASHIKI SEIJI
IPC: F02M25/07
Filed: 1997-07-07
Abstract: The diagnostic system includes a detector (52,54) for determining the engine operating condition. A detector determines the amount of exhaust gas flowing through the catalytic converter. A diagnostic system differentiates between the normal state and a deterioration in a predetermined standard quantity zone where the quantity value assumes a specific value and a diagnosis of the normal state of the catalytic converter is carried out within a predetermined zone of larger amount lying above and outside the predetermined standard quantity zone. The diagnostic system interrupts the diagnosis of the normal state and of the deteriorated state of the catalyst within a predetermined zone with a particularly large amount of exhaust gas which lies above and outside the predetermined zone of large amount. The threshold is fixed despite a changing amount of exhaust gas.

Patent DE-19736255-A1 (DE)
Title: Gray-code decoder compensation circuit
Inventor: BANG HO-YUL
IPC: G11B27/30
Filed: 1997-08-20
Abstract: The compensation circuit includes a central processing arrangement for controlling the disc drive, as well as for setting a certain initial condition, for detecting servo data and a Gray code in synchronisation with the detection of a servo address mark. A generator circuit provides a detection window by detecting amplitude peaks of a hysteresis of an analogue signal read from the disc. A digital servo data generator, provides digital servo data in response to peak values of the amplitude of the hysteresis in a read signal. A detection window generator detects the servo address mark and produces a Gray code detection window. A logic circuit combines the pulse detection window signal, the Gray code detection window signal, and the servo data, to produce a positive and negative Gray code. A circuit separates the therein contained Gray data and Gray synchronisation pattern, and a second logic circuit processes those, to compensate for missing data and synchronisation pattern. A decision circuit decides, wether to output an error to the CPU in response to the Gray synchronisation pattern, and a second decision circuit detects binary Gray data using the pulse detection window signal, and forwards them to the CPU.

Patent DE-19750862-A1 (DE)
Inventor: LOERKE REINHARD
IPC: B31B50/62
Filed: 1997-11-10
Abstract: The invention relates to a method and device for detecting viscous liquids on a solid, especially moving, undersurface (1), e.g. flat packaging material such as paperboard, paper, cardboard, plastic or the like, whereby the viscous liquid, sizing material in particular (2), is continuously deposited on the undersurface. The surface of the deposited viscous liquid (2) is defined and periodically deformed. Subsequently, light is transmitted onto the deformed surface, whereby the brilliance of the light thus reflected, corresponding to the shape of the surface of the viscous liquid in one plane, is given a periodic profile. Said brilliance profile of the light reflected from the deformed surface is received in a spatially and/or chronologically separate manner and converted into a periodic electric signal, enabling the presence of the sizing material (2) to be checked and the discharge of the liquid onto the undersurface to be regulated.
Patent DE-19750947-A1 (DE)
Inventor: BROEKAERT MICHEL
IPC: H04N5/349
Filed: 1997-11-17
Abstract: The video camera comprises a detector 17 having a two-dimensional matrix of Photosensitive elements that accumulate charge, the elements being placed in an image plane of an optical system and being connected to a circuit for periodically transferring the accumulated charges at a determined frequency. An optical deviation member 20 is interposed on the path of light towards the matrix and enables said path to be deflected. A unit 26, 28 for periodically controlling the deviation means causes the image to be deviated in two dimensions, in a first determined cycle each time through a determined fraction of the matrix pitch step size so as to perform space oversampling, and, in a second cycle, each time through a full pitch step size, which second cycle is a multiple of the first. A processor unit calculates the gain differences and the response offsets between the elements by performing comparisons therebetween. In addition to the above spatial resolution improvement of the detected image and compensation for unequal responses of the camera matrix elements, the deviation member may be controlled to compensate for camera vibration.
