Title: An apparatus for recording a video signal
Inventor: SONODA MASAKAZU
IPC: G11B15/02
Filed: 1984-04-06
Granted: 1989-01-19
Abstract: In an apparatus having a record mode for recording video or other information signals in successive parallel information tracks on a record tape by means of a plurality of rotary heads repeatedly scanning across said tape and having respective gaps with different azimuth angles, and in which the apparatus is changeable to a playback mode for causing each of said heads to provide a respective output when it is scanning an information track in which information signals have been previously recorded by a head with a gap having the same azimuth angle; clogging of one or more of the head gaps which would prevent further recording is detected, in the playback mode, by switching from one to another of the outputs of the heads during each period required forthe scanning of the tape by each of the heads, detecting the levels of the head outputs during such switching therebetween, and operating a clog indicator when the detected levels of the head outputs are insufficient during the scanning of the tape by each of the heads. In order to avoid a false clog indication, the operation of the clog indicator is inhibited when the usual fixed head does not reproduce control signals in the playback mode, for example, as when there has been no previous recording of information signals on the record tape.

Abstract: The sealing mechanism comprises a seal ring (33) positioned within a groove (27) circumferential with respect to the passageway (42) of the valve. A convex seating portion (34) of the seal ring extends through an annular opening in the groove, for sealing engagement with a closure member (35). Shoulder portions (36,37) which extend from the sides of the seating portion, abut the sidewalls (29,30) of the groove. The seal ring is compressed in width within the groove, so that a resilient side-sealing force is imparted to the contact of the shoulder portions with the sidewalls of the groove.

Abstract: During the past ten years, the ability to splice DNA from a variety of sources into a recombinant DNA molecule and then to transfer such DNA molecules into different species of prokaryotes and eukaryotes has led to the most exciting revolution in the history of biology. Most of this work has involved the use of bacteria, fungi and animals. Plants have been relatively neglected primarily because suitable vectors were not available. Recently a number of possible vectors have become available but in their natural state they have not been efficient in the transfer and expression of genes from various sources to plant species. The present invention describes some novel discoveries which increase the usefulness of naturally occurring plant DNA vectors in the genetic engineering of plants.

Title: Mechanical pulp hydrosulfite bleaching
Inventor: TORREGROSSA LOUIS OTTO
IPC: D21C9/10
Filed: 1985-03-04
Granted: 1988-12-01
Abstract: A medium consistency mechanical pulp (e.g. RMP, CMP, TMP, CTMP or stone groundwood) is treated to effect efficient reductive bleaching. The pulp, at about 8-15% consistency is simultaneously pumped and degassed utilizing a fluidizing pump (13), and by controlling the pump head to maximize deaeration. The pulp may be immediately passed -- without air introduction -- to a fluidizing mixer (28), where it is mixed with hydrosulfite (dithionite) bleaching chemical. Alternatively, the hydrosulfite may be added directly to the discharge (25) or suction (14) of the pump, and the mixer eliminated. After chemical addition, the pulp is retained at predetermined pH and temperature conditions for a predetermined period of time to effect the desired bleaching, as in an upflow tower (31).

Abstract: The central lubricating system has a motor-driven pump and a time control to operate the pump depending on the operation of the vehicle (e.g. trailer, etc., without its own current source). The power supply for the time control (Z) and the motor (M) is taken from the supply lines to the brake lights. The time control has a sensor (S) that detects oscillations, vibrations or other movements of the vehicle or part of the vehicle. During the vehicle's movement the sensor sends a signal to a second timer (T2) which adds the signals into a sum for comparing with a given time. On exceeding the given time, a third timer (T3) produces a signal that causes the switch-on of the motor when the brakes are next operated.

Abstract: A cluster console unit for connection to a plurality of digital computer systems and high-speed mass storage systems which may be connected together to form a cluster, the cluster console unit allowing an operator to monitor operations of the systems comprising the cluster from the single console unit. The cluster console unit includes an input/output data logger which receives data through from the systems each through a separate port and stores the data in a log file. In addition the data logger transmits the data from each system to a separate communications pipe for each system and control information through a control pipe. An operator interface unit is connected to receive all of the data from all of the separate communications pipes and displays data from selected systems on a terminal screen. When the operator enters operator data for transmission to a system, the operator interface transmits the data and the identification of the system to receive the data to a operator data. The data logger receives the communications from the operator pipe and transmits the data to the identified system. A data scanner scans all data on all of the system communications pipes and generates an event message for transmission over a scan pipe if the data matches preselected alarm data. The operator interface monitors the scan pipe and displays any event messages.
