Title: Optical wavelength multiplexer/demultiplexer and demultiplexer/remultiplexer
Inventor: BUHRER CARL F
IPC: G02B27/28
Filed: 1989-11-17
Abstract: OPTICAL WAVELENGTH MULTIPLEXERS/DEMULTIPLEXERS           AND DEMULTIPLEXER/REMULTIPLEXER            ABSTRACT       A multichannel wavelength demultiplexer has two or more cascaded birefringent filter stages for dividing an input signal consisting of a plurality of adjacent channels of optical signals among a number of outputs, each of said filter stages having a transmission function with even symmetry about optical frequencies at the centers of both the longest and the shortest wavelength channels.   This symmetry,  common to all transmission functions, permits all birefringent filter stages to be constructed from sequences of the same one size crystal element, thereby greatly lowering the cost of construction because solely one size crystal element is fabricated, tested  and assembled.   A multichannel  multiplexer, identical to the above defined demultiplexer, but operated in reverse, is set forth.  A combination multichannel wavelength demultiplexer/ remultiplexer consists of a single birefringent filter stage for use in conjunction with multichannel multiplexer/demultiplexer to divide a common set of adjacent wavelength channels on its primary input between its primary and secondary outputs in any combination, and simultaneously to accept at its secondary input different optical signals within the same wavelength channels as those exiting its  secondary output and recombine them to exit at its primary output, wherein said single filter stage has a transmission function with even symmetry about optical frequencies at the centers of both the longest and the shortest wavelength channels.  This symmetry, common to its transmission function and to those of said multichannel multiplexer/demultiplexer, permits all birefringent filter stages to be constructed also from sequences of the same one size crystal element.

IPC: G10L15/00
Filed: 1989-12-11
Abstract: An inner product computing unit computes inner products of an input pattern whose category is unknown, and orthogonalized dictionary sets of a plurality of reference patterns whose categories are known.  A nonli-near converting unit nonlinearly converts the inner products in accordance with a positive-negative sym-metrical nonlinear function.  A neural network unit or a statistical discriminant function computing unit performs predetermined computations of the nonlinearly converted values on the basis of preset coefficients in units of categories using a neural network or a sta-tistical discriminant function.  A determining section compares values calculated in units of categories using the preset coefficients with each other to discriminate a category to which the input pattern belongs.

Filed: 1990-01-15
Abstract: LOW TEMPERATURE PROCESS FOR THE FORMATION OF CERAMIC COATINGS                           Abstract A single or multilayer ceramic or ceramic-like coating process is provided which can be applied to heat sensitive substrates such as electronic devices.  The process includes the steps of coating the substrate with a solution comprising a hydrogen silsesquioxane resin diluted in a solvent and then evaporating the solvent, thereby depositing a preceramic coating on the substrate.  The preceramic coating is then ceramified to a silicon dioxide-containing ceramic by heating the preceramic coating to a temperature of between about 40 to about 400°C. in the presence of ozone which enhances the rate at which the ceramification proceeds and permits the ceramification of the coating to proceed at low temperatures.  Additional layers of ceramic materials may be deposited over the initial layer and act as passivating and/or barrier protective layers.

Patent CA-2015147-A1 (CA)
Inventor: HEILIGENTHAL CHARLES H
IPC: B60B33/02
Filed: 1990-04-23
Abstract: ABSTRACT OF THE DISCLOSURE    A wheeled carriage has a chassis with a plurality of swivel casters, and a locking assembly actuated by a foot pedal located along the front of the carriage.  Pushing down on the foot pedal rotates a cam that engages a cam follower on a "T" bar frame supporting two locking rings which respectively overlie two of the caster wheels to move the rings into a locking position in engagement with the wheels to lock the wheels and the casters in any position.  The cam follower surface includes a ramp portion engageable by the cam for driving the rings to their locking position and a horizontal latch portion engageable by the cam in its "overcenter" position for holding the rings in their locking position.  A lifter bar is engageable by the user's foot to rotate the cam back off the  follower and permit the rings to resiliently return to their release position.   The cam and follower surfaces are so arranged that a limited rotation of the cam through less than about 25 degrees is sufficient to move the assembly between its release and locking configura-tions so that the locking assembly can be used where only a few inches of clearance beneath the chassis is available.

Abstract: A B S T R A C T      APPARATUS FOR CONTROLLING THE REPLAY OF A                MAGNETIC TAPE        Apparatus for controlling the replay of a magnetic tape is disclosed which comprises a presenter unit 1 which includes a video player 4 and monitor 5, connected to a micro computer 3 via an interface 2, and a coaxial connection 7.  The apparatus provides an authorizing facility for a video tape to be palyed by the player 4, so that an operator may use the computer 3 to store, in a computer file, informatin associated with different sections of the video tape so that under computer control, the video player can be instructed by a subsequent user to wind to a predetermined section of the video tape, play the section and return to a predetermined start point.  The video player 4 is controlled directly by the computer 3 and does not take any ou?ing information from the tape itself, thus minimising wear of the tape.      A preferred feature of the apparatus is that the operator may also add textual information to be displayed on the monitor screen when the video player 4 is winding to the section to be played and rewinding therefrom.

Abstract: INTERNALLY SPIRALED DUCT AND METHOD OF INSTALLATION                  ABSTRACT OF THE DISCLOSURE           A duct for transmission cable including a polymeric tubing having an inner and an outer wall.  Spiral ribs having peaks and valleys are located on the inner wall.  The valleys are adapted to receive lubrication and the peaks form a surface over which cable may travel at reduced friction.  The spiral makes one revolution from about one to six linear feet, at rib heights from about .005 to .125 inch, and the spacing between the ribs is about .025 to .500 inch.   The duct may be located in an outer duct which is normally buried underground, or directly buried or plowed.  There may be a plurality of ducts placed in the ground with an outer duct. Longitudinal ribbing on the external walls prevents rotation. This invention also includes the process of laying a cable which includes pulling the ducts through the outer ducts over the longitudinal ribs and subsequently pulling the cable through the ducts along the spiral ribs, thus reducing the friction and increasing the length of pull that may be done without exceeding the tension strength of the cable.
