Patent WO-9002431-A1 (WO)
Title: Surge protection device
Inventor: LEE BENNY H
IPC: H02H9/04
Filed: 1989-05-10
Abstract: A surge or transient protection circuit is described which operates in an immediate fail-safe mode of failure. If an incoming transient exceeds the transient absorption capacity of the circuit, precision fast-blow fuses are immediately opened to remove current from the load to prevent damage to the equipment connected to the transient suppression circuit and to indicate to the user that the transient suppression abilities of this circuit have been damaged. The transient suppression circuit uses silicon transient voltage suppressor components to absorb the fast-rising edge of transients and also uses slower-acting MOV transient absorption devices for the bulk of the overvoltage transient power. Upon short-circuit failure of any of the suppressor components, the excessive current draw produced thereby results in blowing of the fast-blow fuses.

Title: Magnetic head contour utilizing facets for air film skiving
Inventor: BROCK GEORGE WILLIAM
IPC: G11B23/50
Filed: 1990-04-02
Abstract: To remove the air film adherent to a moving tape (28), rather than have the tape (28) incident upon a steep shoulder of the head, a facet (20, 22) in the contour provides a gradual slope breaking the continuity of the head (18) contour. The break in the contour provides an edge (38, 40, 42, 44) to skive the air adherent to the tape, and the facet (20, 22) provides a gently ramping surface which engages any asperity on the tape (28) surface in a less aggressive manner than occurs when the asperity encounters a shoulder directly. Because of the stiffness of the tape (28), the tape (28) does not contact the head contour over the length of the facet (20, 22); the tape (28) spans the contour between the edges (38, 40, 42, 44) of the facet (20, 22). The air skived from the tape (28) by the facet (20, 22) edge (38, 40, 42, 44) is squeegeed out between the tape (28) and the facet (20, 22), and a slot (48, 50) in the facet (20, 22) increases the cross sectional area through which the air is expelled. The tape (28) spanning the facet (20, 22) is not in contact with the edges (38, 40, 42, 44) of the slot (48, 50), and edge related problems of the prior art are avoided by the practice of the present invention.

Patent WO-9115889-A1 (WO)
Inventor: BETTON ARNOLD L
IPC: F02D45/00
Filed: 1991-04-03
Abstract: A vehicle storage battery protection system that senses a drop in battery voltage (20) to a level at which the battery still retains sufficient power to start the vehicle. If the sensed voltage remains at or below this level for a time greater than the time normally required to start the vehicle, the battery (10) is disconnected from the load (14) and a hysteresis signal (34) is provided to prevent a reconnection as the battery voltage begins to rise after the load has been disconnected. The load is automatically reconnected to the battery upon operation of the ignition switch (18) to restart the vehicle. A reset circuit provides a small test voltage (44) to the disconnected load, and senses a voltage drop caused by operation of the ignition switch to start the vehicle. This sensed voltage drop is detected and causes a main switch (12) to reconnect the battery to the loads.
Patent WO-9202351-A1 (WO)
Title: Faster cycling sprue for molding optical disks
Inventor: MAUS STEVEN M
IPC: B29C45/26
Filed: 1991-06-27
Abstract: Optimum sprue design requires large cross-sectional area of the open aperture during mold filling and packing, yet fast heat removal from the molten sprue during solidification. A 'hollow' sprue configuration (21), wherein an enlarged female sprue bushing (23) cavity of large draft angles is axially aligned with a 'spreader die' type of male member (10) having a generally conical-tipped or parabolic-tipped torpedo shape, works by creating a cross-sectional open aperture consisting of an annular ring. Both male and female may be fitted with internal mass-transport cooling. Since cooling time of the sprue is directly proportional to the wall thickness of the molten plastic, and cooling time is inversely proportional to the plastic/mold surface area, the 'hollow sprue' geometry can provide superior cooling without impaired filling. Varying the relative axial distance of the male and female sprue bushing members can also help, starting with a larger distance before molten plastic injection is started, then urging together the male and female members axially after plastic flow is done.

Title: Programmable digital frequency-phase discriminators
Inventor: KINGSTON SAMUEL CHARLES
IPC: H04L27/00
Filed: 1991-07-25
Abstract: A present invention novel frequency-phase discriminator has input channels for real and imaginary data which are coupled to two programmable despreaders. The first despreader has its real and imaginary outputs coupled to individual programmable data rate filters which have their individual outputs coupled to a quadrant detector that generates a phase angle direction signal and sign magnitude. The second despread has its real and imaginary outputs connected through individual programmable inverters to data rate filters which have their individual outputs coupled to a quadrant selector that selects error signal data rate information from one of four quadrant axes signals. A command generator is programmably coupled to the output of the quadrant detector and to the input of the quadrant selector and provides a selection signal to the quadrant selector which produces a frequency error signal output employed in a frequency lock loop or in a phase lock loop.

Title: High temperature turbulent gasification unit and method
Inventor: WALKER DAVID RAY
IPC: F23G5/14
Filed: 1991-10-24
Abstract: Waste materials are efficiently and completely incinerated in a gasification unit with a minimum amount of fly ash while ensuring complete sterilization of residual materials. The gasification unit includes a refractory liner (4) which is stepped to define primary (10), secondary (12), and tertiary (14) combustion chambers where waste materials are completely incinerated. A fan (200) is adapted to draw combustion air past the outer surface of the refractory liner to initially heat the combustion air while simultaneously cooling the refractory liner. The fan (200) is further adapted to force combustion air under pressure into a preheating chamber (18) in which the combustion air is preheated before passing into the primary and secondary combustion chambers. Turbulence in the combustion chambers, brought about through equalization of air pressure in the preheating chamber, is effected through the provision of tangential air inlets (32) in the walls of the refractory liner. A sloped floor (38) of the refractory liner cooperates with an ash removal device (100) and a secondary burner to ensure complete combustion of the waste materials and sterilization of residual ashes within the gasification unit.
