Title: Hazardous waste containment system
Inventor: BREAUX LOUIS
IPC: E02D17/08
Filed: 1992-01-24
Abstract: ABSTRACT OF THE DISCLOSURE A hazardous waste containment system for preventing the lateral migration of hazardous fluid substances (including both liquid and gas wastes) into the water table, particularly for sites which are located over a fluid impermeable strata of clay (20) or the like.  The system uses an encircling (Fig. 7) barrier containment wall comprising a plurality of slidingly engaged, interlocked, vertical barrier members (3) which extend down to and sealingly interface with the underlying fluid impermeable strata.    The barrier members are slidingly engaged via inter-locking male and female appendages (1 & 4), which mate and form a vertically extended chamber (33), in which a fluid impermeable seal  (7)  is formed.   A method for implementing the invention where caving is a problem includes the augured excavation of a series of adjacent, overlapping, vertical holes (18, 18a) of prescribed depth and width and/or diameter in the soil surround-ing the area to be contained and extending down to the underlying strata, installing the vertical barrier wall in the holes, and sealing the joints formed by each connection and back-filling the holes.  Two and three slotted guide boxes (15; Fig. 1; Figs. 8c & 8d) are used to position and join adjacent sets of barrier members and prevent caving in of the surrounding soil.   The method further includes the utilization of a sealant (25) at the base of the containment wall to prevent leaching under it (Fig. 2).  The system may be used to contain a variety of materials and may be implemented in various soil conditions with similarly successful results.

Title: Transition impact idler for conveyor belt
Inventor: STOLL DONALD L
IPC: B65G21/02
Filed: 1992-03-27
Abstract: Docket RIB 025 P2 Abstract of the Disclosure An impact slider-type idler for use in the transition section of a bulk material conveyor supports the belt against the impact of material to be conveyed in the transition section and, at the same time, guides the belt from the tail pulley of the conveyor into the desired troughing angle.  The slider of this invention employs a plurality of support members extending transversely of the direction of movement of the belt, in side-by-side relation.          The support members are formed with T-shaped supports along the upper surface, which supports are inclined to define an increment of change in the troughing angle.  Each of the support members carries on the T-shaped supports polymeric segments or blocks which extend transversely of the belt.          The angle formed by each section progressively supports the belt between the flat condition as it leaves the tail pulley to a fully troughed position as it exits the transition zone.

Title: Fuel vaporization device
Inventor: LAMBERT RAYMOND A SR
IPC: F02M15/00
Filed: 1992-05-28
Abstract: ABSTRACT OF THE DISCLOSURE A fuel vaporization device utilized in conjunction with  an internal combustion engine which is serviced by a fluid circulat-ing  cooling system and a fuel supply system.   The  vaporization device comprises a compact chamber sealed by two end walls having inlet and outlet ports to allow straight-line flow of the  engine cooling medium through a centrally positioned, fluid-tight heater tube.  Fuel inlet and outlet ports are provided atop the  chamber and  a  plurality of baffle members are  systematically  arranged along the heater tube to inhibit flow of the liquid fuel  through the  chamber and permit escape of fuel vapor through  the  outlet port.   As fuel passes through the compact chamber, heat  is  ex-changed  from the cooling medium in the tube to the fuel  in  the chamber  to  cause vaporization thereof prior to  carburetion  or injection in an engine of a motorized vehicle.  Use of the device reduces  air  pollution and improves fuel  economy  through  more efficient fuel consumption.

Abstract: Abstract of the Disclosure The visual monitoring apparatus includes a transparent tube section with coupling flanges at each end for coupling to  adjacent  conduit   sections  carrying   a   stream  of conditioned sludge which includes agglomerated solid bodies.          Control   rods  extend  between  the  coupling  flanges  to strengthen the tube.  A strobe light is mounted in a housing which is mountable alongside the tube and closely conforms to the shape thereof for confining the strobe light to a predetermined area of the tube and isolating that area from ambient light.   The housing accommodates the control rods therethrough  and  contains  a  mirror  which  directs  light reflected from the illuminated contents of the tube along a viewing path through a view port in the housing which is closed by a door or hatch.  The frequency of the strobe can be adjusted to correspond to the flow rate of the fluid in the tube for creating the visual impression of substantially stopping the movement of the solid bodies in the tube.

Abstract: A bottom fed fluid distribution system is provided which may be used to uniformly distribute fluid to an underlying structure.          The  distribution  system  comprises  a  distribution  pan,  fluid transporting flume, and inlet chamber.   The fluid transporting flume is positioned inside the back edge of the distribution pan and is elevated above the bottom of the pan.   The flume has an opening in its bottom to allow fluid to flow downwardly into the distribution pan.  The inlet chamber is located at the back edge and at one side of the distribution pan.

Title: Method and apparatus for reducing system overhead in a motion detector for a touch screen device in a multi-tasking computer system
Inventor: ZETTS JOHN M
IPC: G06F3/033
Filed: 1992-08-20
Abstract: ABSTRACT OF THE DISCLOSURE        A   method   and   apparatus   for   efficiently distinguishing between different types of input signals simulated  by   a  pointing  device   coupled   to   a multi-tasking computer system.  The pointing device may be a stylus, finger or other device that moves across the surface of a touch screen or the like to generate positional information.  Depending on the response of a delay  timer,  the  motion  of  the pointing device  is recognized by software application programs as input information either from a mouse or from a gesture or a handwriting input mode.  If motion cessation across the screen  is  detected  with  a  predetermined  time-delay period, the system accepts the input information in a mouse-emulating mode.  If motion is detected within the predetermined time-delay period,  the timer is reset. Thus, the system overhead associated with managing the timer can be reduced because the timer is periodically reset and need not be reset after each movement of the pointing device  as in the prior  art.   The periodic resetting  can be  based  on  intervals  of  n  points generated by a moving pointing device, or n real-time units  relative  to  a  given  point  generated by  the pointing device.
