Granted: 1991-07-30
Abstract: ABSTRACT OF THE DISCLOSURE       A manually operated convertible top structure for vehciles having a pivoted tonneau mounted rearward of the passenger compartment.  The convertible top structure includes a plurality of spaced, transversely extending crossbows to form a frame work over which a flexible folding top is disposed.  A pair of rear rails extending in a substantially upright orientation are pivotally mounted to the vehicle at one end and are connected by a control linkage to the side rails.  The rearmost crossbow is pivotally connected to a mounted bracket attached to the vehicle.  The side rails are pivotally connected to the frontmost crossbows for outward lateral movement as the top structure is lowered.  An over-center lock formed of first and second links is pivotally connected between the rear rails and the rearmost crossbows for positively locking the rearmost crossbow on the tonneau when the convertible top structure is in its raised position.  A locating pin centrally mounted on the rearmost crossbow engages an aperture centrally formed in the tonneau for locating the rearmost crossbow with respect to the tonneau of the vehicle.

Granted: 1991-01-15
Abstract: Abstract Retroreflective construction comprising a monolayer of microspheres with associated dielectric mirrors which are hemispherically surrounded by tangentially-oriented, preferably contour-conforming, reflective pigment nacreous flakes.  The dielectric mirrors and reflective nacreous pigment flakes cooperate additively substantially without interfering with each other to provide a high brightness retroreflective sheet.  The novel sheets retain much of their reflectivity after several launderings or drycleanings and, in some embodiments, can be made very flexible, making them well-suited for use as reflective fabrics.

Abstract: ABSTRACT            Electronic data processing equipment for reading magnetically recorded information, particularly document processing systems, contain certain modular units which generate magnetic interference fields.  These interference fields substantially influence the proper functioning of a magnetic read head.  Accord-ingly, the present invention provides a device comprising a read head and a reference head combined as a read system wherein the read head and the reference head have the same mechanical and electrical characteristics.  The two heads are switched together in a difference circuit, wherein the difference signal of the read head and of the reference head is formed from a two-fold inter-ference signal and a read signal.  The difference signal at the output of the difference circuit is supplied to a read electronic circuit.  The invention can operate accurately in the presence of magnetic interference fields and without the necessity of shielding the units generating such fields.  A method is further provided which allows for an accurate determination of magnetically recorded information with a magnetic read head and which is not susceptible to interference by spurious interference fields.  The method comprises combining a read head and reference head as previously described, deriving electrical signals from each head and feeding the signals to respective amplifiers.  The outputs of the respect-ive amplifiers are compared and the interference signals are eliminated from the read signal in the output of a signal amplifier.

Abstract: ABSTRACT OF THE DISCLOSURE    A time compressed color difference signal included in a high definition television signal is roughly compensated for in units of an interval of one-half of a transmission sampling interval in a range obtained by multiplying the amount of a horizontal motion vector by a compression rate.  In addition, the time compressed color difference signal roughly compensated for is finely compensated for in a horizontal direction in units of an interval of one-half of the transmission sampling interval or less by a one-dimensional or two-dimensional spacial filter.          Furthermore, the time compressed color difference signal is compensated for in a vertical direction by a distance corresponding to the amount of a vertical motion vector.          On this occasion, a time compressed color difference signal to be inserted into a position to be interpolated in the present frame is produced using a time compressed color difference signal in a position spaced apart from the position to be interpolated by a distance corresponding to the amount of the vertical motion vector such that the time compressed color difference signal to be inserted becomes the same type of color difference signal as other time compressed color difference signals on a line to which the position to be interpolated belongs.

Title: Telephone protection circuit
Inventor: HUNG FRANCIS Y
IPC: H04Q1/28
Filed: 1988-12-08
Granted: 1992-09-08
Abstract: ABSTRACT           A circuit for protecting sensitive telephone equipment from voltage or current overloads on the TIP or RING line includes a resistor serially positioned in the line and a triac triggered by a voltage differential across the resistor.  A pair of fast diodes is positioned on the line adjacent to the telephone equipment for momentarily clamping the voltage on the line at that point between ground and the voltage supply of the equipment.  The momentary clamping of the voltage creates the voltage differential across the resistor which triggers the triac.  The fast diodes are capable of passing current for a time sufficient to allow the triac to begin shunting current to ground.  An enhanced form of the protection circuit includes a second pair of diodes extending in parallel with the fast pair of diodes and positioned on the line between the pair of fast diodes and the triac.  Inclusion of the second pair of diodes allows the circuit to utilize a triac with a slower turn-on time and a higher on-state voltage.

Abstract: A B S T R A C T          A process for the catalytic conversion of synthesis-gas into a product which comprises naphtha, kerosine and distillate is characterized in that the catalyst is a Fischer-Tropsch catalyst also containing a zeolite, the naphtha fraction contains 60% or less linear paraffins and the kerosine and distillate fractions contain more linear paraffins and olefins than found in the naphtha fraction.  Reduction of the relative amount of straight chain material in the naphtha fraction increases the octane number and so enhances the quality of the gasoline product, while the high quality of the kerosine and distillate fractions is maintained.
