Abstract: Abstract Of The Disclosure A data recording and reproducing system in which a disk having a plurality of data tracks has a track following code stored thereon, enabling a recording head moved by a servo system to be centered in relation to a desired track. The code includes, on one side of the track centerline, first regions of magnetic flux in which there is a first area of magnetic flux reversal, and, on the other side of the track centerline, second regions of magnetic flux in which there is a second area of opposite flux reversal adjacent the first area.  The lines of flux in each area are equal.  A recording head, when centered on the track centerline, detects no difference in the number lines of flux between the first and second areas due to its self-nulling properties, though the output signal of the head, which represents the rate of change of detected flux as the head traverses the two areas, may show differences at different points in time of detection.  An integrator integrates the head out??? signal, which integrated signal thus represents such difference in the number of lines of flux and is an error signal used in the servo system to move the head on center, is needed.  If the head is off center, a difference in number of lines of flux will be detected, thereby producing the error signal to move the head on center.

Abstract: A B S T R A C T                  An on-line particle size analyser which is able to take measurements on material flowing along 8 line in real time and thus enable automatic process controls to be effected.   The apparatus periodically takes a sample of material, dilutes it to a predetermined concentration in a turbidimeter, and thence passes it to one of a number of vertical sedimentation cells in which a particle size analysis is carried out.  Each sedimentation cell is formed simply as an enlarged part of a line passing from the turbidi-meter around a loop back to the turbidimeter and, in order to file the respective sedimentation cell, the sample is pumped round the loop until steady-state conditions have been reached, whereupon the flow is stopped and measurements begun.          When the measurements, which are carried out by optical means, are completed, the whole loop, including the sedimentation cell is automatically flushed out.   A central control unit controls the sequence of operations, and enables virtually continuous monitoring of the material flowing down the line.

Abstract: ABSTRACT              A modulator for amplitude modulation of a first input signal with a second input signal, each input signal having positive and negative excursions relative to a re-ference level.  The input signals are suppressed during the modulator process and only the product terms are obtained as an output signal.  The modulator comprises a first and a second converter circuit for converting the first and second input signals respectively.  Each converter converts its input signal into a first and second signal current of one polarity relative to a datum level, the value of the first signal current corresponding to that of the input signal for its positive ex-cursions and being equal to the datum level for the inputs sig-nal's negative excursion.  The valve of the second signal cur-rent from each converter corresponds to that of its input sig-nal for the negative excursions and equal to the datum level for the input signal's positive excursions.  A multiplying device, with first and second outputs, is connected to the converter circuits and supplies at its first output the sum of products of the first signal currents from each converter and of the second signal currents from each converter.  This multiplying device supplies, at its second output, the sum of the products of the first signal current from the first con-verter and the second signal current from the second converter and of the second signal current from the first converter and first signal current from the second converter.  A difference producer, connected to the outputs of the multiplying device, produces the desired modulated output signal.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and system for more efficiently utilizing pre-sently available and prospectively available two-way communi-cation channels for communication between mobile telephones and either fixed telephones or mobile telephones.  A large mobile telephone service area is divided into a plurality of smaller zones, and channels are assigned to the zones in a manner which permits the reuse of channels in zones on a non-interfering basis.  A control signal is broadcast over a de-signed one of the channels assigned to each zone by equipment at a fixed station in each zone under the control of a central control unit.  Each mobile telephone monitors one of the desig-nated control channels in accordance with the signal reception characteristics thereof.  When a call is placed over the de-signated control channel, a service or talking channel is assigned to serve the call and the mobile unit is remotely tuned to the assigned talking channel.  Provision is made for using the designated control channel as a talking channel if neces-sary, for assigning additional channels to a fixed station on the basis of user density, and for maintaining communica-tions between two parties as a mobile unit moves from one zone to another.  A novel mobile telephone unit operable in accordance with the techniques of the present invention and providing simplified call placement and control is also dis-closed.

Granted: 1981-09-15
Abstract: An air filter unit of the pleated media, high efficiency type wherein the media pleat edges are sealed to the supporting frame to prevent bypass of air with a ceramic adhesive and fibrous ceramic mat which allows the unit to be exposed to high temperatures (e.g., up to 2000.degree.F.) without danger of seal breakdown.  While in the form of a slurry the adhesive is applied, for example, with a trowel to the zig-zag pleated edges of the media which, together with corrugated spacers, forms the filter core.  The latter is then surrounded on four sides by the compressible mat of fibrous ceramic material and inserted in a box-like support frame with the slurry filling the space between the pleated edges of the media and the fibrous mat.  The filter core and surrounding mat are assembled with the support frame while the slurry is still wet whereby, upon hardening, the resulting layers of ceramic cement provide a complete, heat-resistant seal while avoiding cracking in normal handling due to the resilience of the compressed fibrous mat which maintains an airtight seal between hardened ceramic and support frame.

Abstract: BOARD SEPARATOR                       Abstract A board separator apparatus for separating boards from groups of boards is described.  The separator apparatus includes an input conveyor for feeding the groups of boards in a vertical position longitudinally into a transfer box, which is pivoted to transfer the boards onto an elevator member in the separation means. The elevator member lowers each group of boards into a separation position where they are held by a pressure plate against separator arms.  The separator arms are moved outward into three different separator positions, thereby selectively causing three boards in a group to be moved one at a time off of the elevator into a separated condition.  The separated boards slide down a ramp from the elevator member onto an output conveyor which transports the boards laterally away from the separator in a horizontal position.  The boards are fed onto the output conveyor with the wane side of the boards facing up when such boards are cants cut from the side of a round log.  These cants are thereby separated and oriented in position to be fed into a resaw section which detects and removes the wane portions of such cants.
