Patent EP-0317954-A2 (EP)
Inventor: BEERMANN EWALD HELMUT
IPC: B26B5/00
Filed: 1988-11-22
Abstract: A knife with an exchangeable blade, which is locked by its end face by clamping in an axial slot at the front end of the handle between a clamping plate and the base of the slot, is designed in such a way that the clamping plate is held on both sides slidably in lateral longitudinal undercuts of the slot which approach the base of the slot at the rear end of the latter. When the clamping plate is pulled back, the blade is held owing to the wedge effect and the static friction between the clamping plate and the base of the slot. It is possible to exchange a blade without tools or other aids. The clamping plate, displaceable via an actuating projection, carries on its underside a tongue-like projection which engages in an axial slit in the blade which is open towards the rear end. <IMAGE>

Abstract: In the development of future, integrated broadband networks, the design above all of the switching networks and their controllers is of particular importance. In a switching network constructed in the manner of a space- division multiplex switching network, each switching point is equipped with a comparator, which compares the address of the serving trunks, which are disposed in columns, with the routing information. In the event of multiple correspondence within a column, a decision circuit allocated to the serving trunks determines the order in which the switching points are to be activated. An input buffer is connected to each offering trunk, in which buffer the blocks are temporarily stored until they reach one of the serving trunks. To prevent the occurrence of log jams in the switching network, an input buffer is allocated to each switching point or the switching network is divided up into columns and built up from units which are similar in structure. <IMAGE>

Abstract: A double display mode for differential gain provides the capability of accurately determining the differential gain of a video system in response to a video test signal without using graticules on a display device. A detected chrominance peak level signal is displayed as a positive and a negative trace on the display device. An offset signal is added to the detected chrominance peak level signal to obtain an overlay on the display device of a first selected point of the traces, and then the offset signal is varied to obtain an overlay on the display device of a second selected point of the traces. The difference in values of the offset signal between the two selected points are used to determine the differential gain of the video system.

Abstract: Plural magnetic transducing heads are employed to record and reproduce video information that is stored in a segmented format. One head is in contact with the magnetic recording tape while the other head is out of contact with it. The position of the head which is in contact with the tape is controlled by a suitable ramp voltage generated in accordance with the ratio of actual tape speed to normal play speed, to maintain the head generally aligned with a track on the tape. The other head, which is out of contact with the tape, is also positioned in the same fashion. When a repositioning of the heads is required, a determination is made whether the track of information being reproduced by the head in contact with the tape relates to a particular segment of a field, for example the last field. If so, the head which is out of contact with the tape is appropriately repositioned so that it is in the proper location when it comes into contact with the tape to begin scanning the first segment associated with the next field that is being reproduced. Once the other head has come out of contact with the tape at the end of the previous field, it is repositioned to bring it to the location of the head which is now in contact with the tape.

Abstract: An improved directional drilling tool permits changing the downhole drilling assembly between straight and directional drilling configuration by manipulation of conventional drilling fluid flow controls at the surface. A housing (2), with stabilizer features (2H), shrouds a shaft (1, 5, 9) which functions as an extension of the drill string and attaches to a drill head. A drilling fluid flow rate responsive selector valve (6) is situated in the shaft and responds to drilling fluid flow rate manipulations to change assembly configuration. In the straight configuration the shaft remains straight and is rotationally locked to the housing. In the directional configuration the housing is rotationally unlocked from the shaft, normally after directional orientation, so that the shaft can rotate through it. The same action tranversely displaces the shaft midsection relative to the housing and the shaft and drill head below is angularly deflected by way of a hinge arrangement near the drill head end of the housing. The process can be reversed for straight drilling by further drilling fluid flow rate manipulations.

Abstract: The control track of the optical disk (2) is scanned by optical pick-up means (18). Data and clock are detected from the signal obtained by above scanning, and the missing state of the clock is further detected. In addition, the shifting direction relative to the control track of the optical pick-up means is detected. When data indicates an error and the clock includes a large missing portion, the optical pick-up means (18) is shifted in a direction opposite to the shifting direction thereof. In the case where there is no shifting direction signal, the optical pick-up means (18) is shifted in a fixed direction. Such an operation is repeated until no shift is detected. In an alternative implementation, the control track of the optical disk (2) is scanned by optical pick-up means (18). Data and clock are detected from the signal obtained by above scanning, and the missing state of the clock is further detected. When data indicates an error and the clock includes a large missing portion, the optical pick-up means is shifted in a fixed direction. Thereafter, the width of the missing portion of the clock is detected. The optical pick-up means (18) is shifted in a direction opposite to the above when the missing width is widened and in the same direction as the above when the missing width is narrowed. Such an operation is repeated until no shift is detected.
