Abstract: A video tape recording/reproducing apparatus for reproducing video signals recorded in successive parallel tracks on a magnetic tape, includes a magnetic head movable in a direction generally along each of the tracks in a scanning path from a beginning end to a concluding end thereof for reproducing signals recorded therein, and a bi-morph leaf for mounting the head and being operative to deflect the head in a direction transverse to the direction along the tracks. During the scanning operation, the bi-morph leaf is supplied with a dithering signal for wobbling the head transversely with respect to the longitudinal direction of the record tracks, a tracking error signal to correct deviations of the head trace from the tracks to be scanned and a slant compensation signal to correct any inclination tracking error of the head. During the non-scanning operation, a jump signal is supplied to the bi-morph leaf for deflecting the head to accurately scan the beginning of the tracks. The present invention also includes a sample and hold circuit and a comparator circuit for producing a polarity signal corresponding to the direction of any deviation between the scanning trace of the head and the track then being scanned thereby, at the beginning end of the scanned track, and an UP/DOWN counter for producing and storing a control signal and for supplying the control signal to the bi-morph leaf so as to control the latter to deflect the head to accurately scan the beginning ends of the tracks, the counter being controlled by the comparator circuit to change the value of the stored control signal by an incremental amount by counting either UP or DOWN during each scan in accordance with the direction of the deviation at the beginning ends of the tracks.

Abstract: The invention relates to a unit and a plant with such a unit as part thereof, based on the use of eddy currents for turning mechanical energy into heat energy for heating a fluid. The unit has a driver with at least one permanent magnet and is mechanically driven and takes effect on a rotor placed on the other side of a separating wall. The rotor is fitted with at least one permanent magnet and is turned by the magnetic attraction. The magnetic field, turning in relation to the separating wall, is at the same time responsible for causing eddy currents in the wall and for this reason for the production of heat which is given up to the fluid. In a preferred form of the invention, the rotor side of the unit is completely encapsuled and only one side of the separating wall is acted upon by the fluid so that even fluids that are strong or unstable chemicals may be heated. The heat producing unit may be automatically controlled with almost no time lag and the temperature may be automatically controlled within very fine limits.

Abstract: A glass-fibre cable has been provided with a signalling conductor for signalling liquid which has penetrated into the cable sheath. The signalling conductor is a glass fibre, which is inserted in a protective perforated sheath in the usual way. The inner periphery of this sheath is provided with a wave-shaped pattern on one side, whereas the opposite side is provided with a layer of swelling powder. As soon as the liquid which has entered the cable, reaches the swelling powder, the volume of this swelling powder will considerably increase, in consequence of which the glass fibre will be pressed against the wave-shaped pattern. This causes microbending which involves a strong, measurable attenuation of the light signal transmitted through the glass fibre. The swelling powder can be applied to a substrate.

Title: Method and device for coupling a seismic detector to a bore hole wall
IPC: G01V11/00
Filed: 1983-07-12
Granted: 1987-10-14
Abstract: The present invention relates to the acquisition of seismic signals at different levels in a borehole, in response to the generation of seismic waves by a source placed on the surface or in the vicinity of the surface. The acquisition is carried out by means of a sonde suspended in the borehole from a cable and equipped with an anchoring pad. At each acquisition level, the pad is anchored in the borehole wall to couple the sonde to the formation, and then the pad is released from the wall once the acquisition is over. The signals acquired are then sent to the surface by means of the cable. The force with which the pad is anchored in the wall is controlled by means of a feedback arrangement which includes a sensor arranged in the pad itself. During the sonde movements from one level to another, the pad is kept in contact with the wall.

Abstract: © Digital switching network for switching through subrate channels. The multiplexed subscriber's channels contain eight-bit words, each bit of which can form part of another signal. The number of bits in each word for a single signal is determined by the original rate of the signal. Each of the signals must have the possibility of being switched through to another destination. For that purpose it may be necessary to change the position of bits within a frame. Hence a separate time (6) and space step (4) has been arranged between the input time step (2) and the switching matrix (8). After that the switching matrix switches through eight-bit words. The positions of bits within a word can be exchanged in an additional space step (10) between the switching matrix (8) and the output time step (12) in order to make it possible to fill the outgoing frames as completely as possible.

Abstract: A combinatorial circuit component for television sets with an overload protection circuit on the primary side and a secondary-side regulating circuit and starting circuit with final disconnection of the mains section. The protective circuit, which comes into play in the event of anomalies on the primary side, causes a jump in the negative voltage on the secondary side. This is compared with a secondary (standby) voltage, created independently of the combinatorial circuit, in a comparator, which supplies a control voltage to which the secondary protection circuit responds thus interrupting the excitation of the switch in the mains section.

Abstract: An improved operating system for increasing the data transfer rate between a host computer (101) and a data terminal (104...107) while still allowing the utilization of flow control. The system is useful in multi-user computers where the connected data terminals are communicating large amounts of data with the host computer system. During the transfer data from the host computer to the terminal, the operating system controlling the host computer first disables the use of the designated characters as flow control characters, starts the transfer of information to the terminal, performs operations to determine whether or not the terminal is approaching the point where it can no longer receive data, and enables the utilization of the designated characters as flow control characters when the terminal reaches the latter point. The operating system thus allows the data terminal to control the amount of characters received and a similar operation is performed during the transmitting of characters from the data terminal to the host computer system.
