Patent EP-0289068-A1 (EP)
Inventor: KERBART YVES
IPC: E21B44/00
Filed: 1988-04-05
Abstract: The invention relates to a procedure for measuring the rate of penetration V F  of a drill bit fixed to the lower end of a drill string lowered into a well. 
     During an initial period, the well is drilled keeping, on average, the value of weight F of the drill string measured at the surface relatively constant, and the momentary values of the drill string rate of penetration V S  and the weight F are measured at the surface at different successive moments. The value of the drill string average rate of penetration V SM  at the surface is determined from the values of V S  measured and the successive values of dF/dt of the first derivative with respect to time. The coefficient of apparent rigidity of the drill string during the initial period is then determined from the values of V SM , V S  and dF/dt. Finally, the rate V F  is calculated.

Abstract: A device for use with an image forming apparatus for circulating developer from a cleaning device (8) to a developing device (7) through a circulating passage (13) having a space (40) for allowing a portion of the developer to remain temporarily. The device includes a conveying member (14) for conveying developer in the circulating passage in such a way that developer is moved at a smaller rate in the downstream region thereof than in the upstream region. Supplying means (17a) from the passage (13) into the developing device (7) moves developer at a greater rate than discharging means (33) from the cleaning device (8). The discharging means (33) the the conveying member (14) are driven during operation of the photosensitive drum (4). The supplying means (17a) and means (18) for feeding developer to a developing section of the developing device are interrelatedly driven. The member (17) for supplying developer into the developing device has oppositely directed spiral portions (17a,17b) at its upstream and downstream portions respectively and a plurality of substantially plate-like members (17c) at its intermediate portion. These measures all improve circulation of developer.

Abstract: An infant incubator (20) is disclosed having a hood (34) that encloses the infant compartment. In the base (28) of the incubator (20) is the heating and ducting means and which provides heated air through an ever open outlet (70) in the base (28) and which heated air passes from the base through a flow path formed by the hood (34) that circulates around the infant and re-enters the base through an inlet (74). That heated air is thus introduced into or along the access door (38) in the front of the hood (34) from the outlet (70) and travels through or along the access door (38) and through or along the hood (34) around the infant and is returned to the base (28) for recirculation. When the access door (38) is opened, it pivots out of the way of the air flow from the ever open outlet (70) in the base (28) and the flow of heated air continues over the area normally occupied by the access door (38) when in its closed position forming an air curtain to protect the environment of the infant compartment. The flow of air thereafter enters the flow path formed by the hood (34) in the same manner as the path of the air flow when the access door (38) is closed and eventually re-enters the base (28) through the inlet (74).

Abstract: A circuit for reading from an optical recording medium having a clock track which is provided in parallel with data tracks and holds recorded clock bits forming a predetermined optical pattern. A reader circuit reads a clock track which contains a series of regularly arranged clock bits and some irregular clock bits that disturb the regularity of the former clock bits. This circuit includes a phase-locked loop (PLL) circuit for receiving the clock signal read from the clock track, and irregular clock detecting means for comparing the clock output of the PLL circuit with the read signal to generate a detect pulse when the disturbing irregular clock bit is detected. Even if the PLL circuit gets unlocked temporarily, the head word is recognized according to irregular clock bits provided in the clock track when the PLL circuit returns to the locked condition. Therefore, the data which are read subsequently can be properly recognized. Further, the invention can be real­ized without decreasing the recording capacity of the optical recording medium. 
 
 
     ABSTRACT 
     A reading circuit for an optical recording medium having a clock track having a predetermined optical pattern formed along data tracks and comprising at least one irregular clock bit disposed in a line formed of regular and periodi­cal clock bits, breaking the regularity of the periodically arranged clock bits, which circuit comprises: a phase locked loop (PLL) circuit receiving read clocks obtained by reading the clock track; and an irregular clock detecting means comparing a clock output from the PLL circuit and the read signal and generating a detection pulse when it detects the irregular clock bit which breaks the regularity of the periodically arranged clock bits. According to the present invention, when the PLL circuit is reinstated into the locked position after the PLL circuit has fallen into the out-of-locked position, a leading word can be identified by the irregular clock bit provided in the clock track. There­fore, the read data thereafter can be recognized accurately. This can be attained without lowering the recording capacity of the optical recording medium.

Abstract: Beim Oszillieren einer Stahlstranggiesskokille wird in Abhängigkeit der Strangabzugsgeschwindigkeit die Hubhöhe eingestellt. Zur Verbesserung der Strangoberfläche und zur Verhütung von Oberflächenfehlern und Durchbrüchen bei Klebergüten, insbesondere beim Giessen mit hohen Strangabzugsgeschwindigkeiten, soll eine sägezahnartige Oszillationsbewegung, die im wesentlichen während der ganzen Abwärtsbewegung den Strang überholt, eingesetzt werden. In einem ersten Bereich mit Strangabzugsgeschwindigkeiten bis 0,8 - 1,2 m/min soll die Oszillationsfrequenz von etwa 60 - 120 Hüben pro Minute auf 120 - 200 Hübe pro Minute angehoben werden. Bei einer weiteren Erhöhung der Strangabzugsgeschwindigkeit über 0,8 - 1,2 m/min in einem zweiten Bereich soll die Oszillationsfrequenz konstant gehalten und die Hubhöhe zur Strangabzugsgeschwindigkeit unter Beibehaltung einer Negativstripzeit von etwa 0,1 s vergrössert werden.
