Abstract: ABSTRACT OF THE DISCLOSURE     The separating device is based on the principle of a simple filtering operation in order to extract the sound signal from the "image plus sound" signal delivered by a television transmitter.  The device comprises subtraction means whereby a processing signal obtained from the intermediate-frequency image signal Fi is subtracted from a signal collected at the output of the transmitter.  Adjustment of the transit time, amplitude and phase of the processing signal makes it possible by means of this subtraction to remove from the collected signal all image frequencies which are close to the sound frequencies to be extracted, with the result that the sound signal can thus more readily be obtained by filtering.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for feeding individual substrates from the top of a stack of substrates upon demand includes a paddle wheel having paddles that are semi-cylindrical. The paddles buckle upon contact with the substrates rather than bending and thereby providing reduced normal force sensitivity to paddle deflection and reduced pressure since the force of buckling is a function of thepaddle cross-section rather than paddle length for all areas of the paddles except near the paddle wheel hub. The semi-circular blades reduce misfeeding and multifeeding while having an extended wear life.

Abstract: OPTICAL STORAGE SYSTEM HAVING EXPANDED CAPACITY     Abstract The present invention relates to a process for optical storage which utilizes a photopolymerizable liquid crystalline material having cholesteric optical properties.  By selectively adjusting the reflectance or transmittance properties of the recording medium such that specific wavelength bands of light are reflected or transmitted, and then substantially permanently fixing the reflectance or transmittance characteristics of the film by photopolymerization, multiple wavelength-dependent information can be stored in each dot.  Accordingly, the capacity of the recording medium is substantially expan-ded when compared to conventional optical storage media.

Abstract: METHOD OF AND ARRANGEMENT FOR ORDERING OF MULTIPROCESSOR           OPERATIONS IN A MULTIPROCESSOR SYSTEM Abstract To lock use of shared information to itself in a multiprocessor system having two independently and asynchronously operating processors whose main store units duplicate each other's contents, a processor must cause an atomic read-modify-write (RMW) operation to be executed on a semaphore in the duplicated main store units of both processors.  To properly order execution of multiple such RMW operations, arbiters of system buses of the two processors communicate over an interarbiter channel.  The arbiter of a source processor that wishes to perform an RMW operation notifies the other processor's arbiter over the interarbiter channel.  Simultaneous attempts at notification by both arbiters are resolved in favor of one of them that is designated the master.  The notifying arbiter prevents its processor from performing another RMW operation until the one RMW operation has completed thereon, but permits other operations to proceed normally. The notified arbiter prevents its processor from performing another RMW operation until the one RMW operation has been transferred via interprocessor links and bus from the source processor to the notified arbiter's processor and has been performed thereon, but permits other operations to proceed normally.  Thus multiple RMW operations are performed on both processors in the same order asynchronously and without impacting performance of other operations.

The  cutter includes a follower to trace the actual  configuration of the pipe and thereby to offset differences from one pipe to the next.  An array of clamps are provided to align the outer pipe halves relative to one another and to facilitate the reattachment.

Abstract: ABSTRACT OF THE DISCLOSURE A tractor provided with a cable reel at one end and a plow at the trailing end includes a system to monitor tension applied to the cable during underground placement.  A capstan engages the cable while driven by a hydraulic motor and the pressure of the fluid supply to the motor is monitored by a pressure transducer.  An electrical signal from the pressure transducer is fed to a control which also receives a setpoint signal corresponding to a maximum allowable tension on the cable.  An output signal from the control is used to slow down or stop advancing movement of the vehicle and a second signal is used to operate a valve to divert fluid pressure from the hydraulic motor.  Tension on the cable extending between the capstan and the reel can be monitored as well as tension on the cable between the capstan and the plow.

Abstract: ABSTRACT    A data communications sustem (Figure 1) is described that covers a geographic area divided into a plurality of non-overlapping zones (Figure 2) and includes a general communications controller (GCC, 104), a plurality of channel communications modules (CCM 106, 108, 110, 112) and associated transmitters (114, 120, 124) and receivers (116, 118, 122, 126, 128), and a plurality of portable radios (130, 132, 134).  Message signals carrying alphanumeric information are communication between the GCC (104) and the portable radios (130, 132, 134) by way of a radio channel.  Each CCM (106, 108, 110, 112) takes a signal strength measurement every time it receives a message signal from a portable radio (130, 132 or 134). The GCC (104) gathers the signal strength measurements from the CCM receivers (116, 118, 122, 126, 128) receiving the same message signal and computes an adjusted signal strength for each zone.  The GCC (104) then selects the zone having the largest adjusted signal strength for determining the location of the portable radio (130, 132 or 134) that transmitted the message signal.  Whenever the GCC (104) transmits a message signal to a portable radio, the CCM transmitter (114, 120, 124) is used that covers the zone having the largest adjusted signal strength for the last transmission from that portable radio (130, 132, 134) in other zones using non-interfering CCM transmitters (114, 120, 124), information throughput is greatly enhanced.

Granted: 1989-09-26
Abstract: ABSTRACT OF THE DISCLOSURE   Disclosed is a sliding gate valve which may be employed on the side of a furnace as a furnace valve, in which the mechanism is so structured that the shut off occurs by directing the slide gate to the up position rather than the down position.  In addition, to facilitate a reduction in space at the slide gate, the slide gate is desirably configured to be asymmetrical, with the short end extending upwardly from the pour opening in the nozzle.  A refractory lined heat shield protects the sliding gate carrier and also serves to mount a collector extension when used.  More specifically, the slide gate is provided with a metallic frame which retains a monolithic refractory into which erosion resistant refractory inserts or preformed members are cast. Means are desirably provided to remove the spent refractory for remanufacture thereby reclaiming the casting.  Similarly in the top plate, means are provided for remanufacture and for facilitating proper orientation of erosion-resistant refractory inserts such as zirconium oxide in the manufacture of the stationary plate.  The top plate is symmetrical to provide full travel pressure face relationship with the sliding gate.  Both the stationary plate and slide gate casting having spring pad back up reinforcements.  The top plate desirably has means for securing a well nozzle to it.
