Title: Method and apparatus for treating oil-water-solids sludges and refinery waste streams
Inventor: SKINNER JAMES L
IPC: C02F11/13
Filed: 1986-11-06
Granted: 1990-11-06
Abstract: ABSTRACT OF THE DISCLOSURE         Heavy  hydrocarbon  containing  sludges  such  as refinery waste streams, oil storage tank sludges and marine oil tanker ballast are treated by passing the sludges in a flow stream through an indirect dryer to vaporize liquids having a boiling point at atmospheric pressure of less than about  700°F  and  to  provide  substantially  dried solid particles discharged from the dryer.  The dried particles, containing heavy hydrocarbons as a coating or as a part of the solids,  are conducted to a combustor/oxidizer and exposed to a high velocity flow stream of oxygen containing gas, typically low pressure forced air, to burn the residual hydrocarbons in the solids and to reduce heavy metals and the like  to  oxides  thereof.   A  sludge  handling  system includes a rotary disk type  indirect dryer connected to a lift pipe type combustor/oxidizer for thorough exposure of the dried  solids to an oxygen  containing atmosphere.          A centrifigal or cyclone type gas-solids separator receives the flow stream discharged from the lift pipe and a portion of the dried solids may be diverted after discharge from the dryer back to the dryer inlet to reduce the moisture content of the sludge flow stream introduced to the dryer to minimize  caking  and  clogging  of  the  dryer  itself.

IPC: G09G3/36
Filed: 1987-09-10
Granted: 1992-02-25
Abstract: ABSTRACT    An active matrix display device of an improved and simplified configuration and a driving method are disclosed.  The display de-vice according to the present invention is characterized in that data bus lines and scan bus lines are separately formed on first and second transparent substrates respectively and the drain ele-ctrode of each TFT (thin film transistor) on the second substrate is connected to the scan bus line to be addressed next.  This con-figuration eliminates the earth bus lines of the prior art.  This arrangement has the effect of simplifying the bus line design and obtaining a nigher yield and an increased opening rate for each display element.  In order to drive the device, and address pulse having a stepped waveform is used.  Each address pulse has Vgc, and Vgoff levels, and a width of two horizontal scan time.          The first step of address pulse Vgc corresponds to the address time of the adjacent scan bus line to be scanned previously; and the second step Vgon corresponds to the address time for the TFT to be scanned.  The present invention discloses a voltage relation for waveforms of the address pulse and data pulse in order to ob-tain a high quality display.

Granted: 1991-12-17
Abstract: Abstract of the Disclosure A brake system wherein an input from an operator operates a first master cylinder (12) produces first and second hydraulic fluid pressures.  Flexible conduit (22 and 24) carries the first and second hydraulic fluid pressures to an actuator (26) for a hydraulic power booster (28).  A plunger (58) in the actuator (26) reacts either to the first hydraulic fluid pressure or the second hydraulic fluid pressure by moving to operate the hydraulic power booster (28).  Operation of the hydraulic power booster (28) provides an input force to develop first and second operation fluid pressures in a second master cylinder (30) to effect a brake application.

Title: Electromagnetic contactor with energy balanced closing system
Inventor: BAUER JAMES A
IPC: H01H47/00
Filed: 1988-02-05
Granted: 1991-12-03
Abstract: ABSTRACT OF THE DISCLOSURE An electromagnetic contactor or motor controller is taught in which an energy efficient bounceless contact closing operation is utilized.  An electromagnetic closing coil voltage is sensed by the contactor control system and compared against a memory menu of stored delay angles for a wide  range  of  sensed  voltages.   The  delay  angles  are applied to the conduction interval of a triac or similar gated device which is connected in series with the coil for controlling current flow therethrough.  Depending upon the voltage sensed the amount of current flowing through the coil on a half cycle by half cycle basis is varied by the control system.  The energy supplied to the armature of the electromagnetic  closing coil  is  such that  the armature attains a predetermined velocity during its closing opera-tion which predetermined velocity is approximately suffi-cient to allow the armature to move to its final fixed closed disposition where  the  air  gap between it  and  a permanent  magnet  is  reduced  to  zero  at  a velocity of approximately zero.  Generally only  that much energy  is supplied to the armature which is just needed to close the contacts and no more within practical limits.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for interconnecting electronic circuits using nearly pure soft annealed gold mechanically compressed within through-plated holes.          The invention has its application in attaching integrated circuit dice directly to circuit boards by ball bonding gold wires to the bonding pads of the integrated circuit dice in a substantially perpendicular relationship to the surfaces of the dice and inserting the gold leads into through-plated holes of circuit boards which provide an electrical and a mechanical con-nection once the leads are compressed within the through-plated holes.  The present invention also finds its application in the interconnection of sandwiched circuit board assemblies where soft gold lead wires are inserted into axially aligned through-plated holes of the circuit boards and compressed so that the gold lead wires compress and buckle within the through-plated holes, forming an electrical connection between the cir-cuit boards.
