Title: Screening assembly for soil
Inventor: LAPRADE REAL R
IPC: B07B15/00
Filed: 1992-07-16
Granted: 1998-05-05
Abstract: The  present  invention  is directed to  a  method  for screening  granular  material which makes use of  a  tilted  belt conveyor  over which is mounted,  at its lower end,  a  screening device for the granular material which is dropped on the upwardly movable belt conveyor.  The screened material is collected at the upper end of the belt conveyor.   The invention is also  directed to the screening assembly which comprises a tilted conveyor means over  which  is  mounted a  rotatable  cylindrical  drum  axially oriented in the direction of the conveyor means and a mixed  soil receiving bucket mounted over the conveyor means upstream of  the cylindrical  drum.    The  bucket  is  provided  with  means  for transporting a mixture of soil and debris towards the cylindrical drum.   The  cylindrical drum while rotating allows the  soil  to drop  on the conveyor means while the debris are rejected at  the lower end of the drum.  The invention particularly makes use of a screening  drum  which  includes  a  cylindrical  meshed   screen supported  by  two end rings at both ends of the  meshed screen.          The  drum  is rotated by a pair of driving wheels  located  under each  of the rings.   One of the rings includes an  outer  radial flange  which  is  adapted  to  abut on  a  pair  of  wheels  for preventing the tilted drum from sliding downwardly.

Title: System and method for transmitting data in an optical traffic preemption system
Inventor: HAMER STEVEN M
IPC: H04B10/508
Filed: 1992-09-28
Granted: 2003-07-01
Abstract: An optical data communication system for transmitting a stream of light pulses, including both priority pulses and variable data pulses from an optical emitter atop certain vehicles, such as police cars, etc., to a detector mounted along a traffic route. The method allows variable data to be transmitted in a stream of light pulses along with priority pulses. The variable data can include an identification code that uniquely identifies the emitter, an offset code that causes a phase selector to create a traffic signal offset, an operation code that causes traffic signal lights to assume at least one phase, and a range setting code that causes a phase selector to set a threshold to which future optical transmissions will be compared. Phase selectors separately identify received priority and data pulses and assemble data derived therefrom. The data may include a discrimination algorithm for tracking a plurality of optical transmissions with each detector channel. The optical emitters may also be provided with a coincidence avoidance mechanism which causes overlapping optical transmission from separate optical emitters to drift apart. The optical signal format allows variable data to be transmitted while maintaining compatibility with prior optical traffic preemption systems.

Title: Kci drilling mud treatment for disposal system
Inventor: FLEMMER HENRY
IPC: E21B21/06
Filed: 1993-09-30
Granted: 1998-11-17
Abstract: A method is provided for treating used potassium chloride (KCI) drilling mud for disposal. The process comprises feeding the mud into one end of a rotary tube, advancing the mud through the rotating tube and heating the mud by cascading action using lifters, to expose it to a hot gas stream, thereby partially drying the mud to lumps, further modifying the lumps by contacting them with a burner flame to form clinker pellets, and finally contacting the clinker pellets with a second flame to complete the drying process, producing dried clinker pellets containing the majority of the KCI in the mud, the pellets having a structure that resists the leaching action of water. The pellets further lend themselves to being evenly distributed over fields, so that unwanted excessive concentrations of KCI can be avoided.

Title: Imaginograph

Filed: 1992-09-21
Granted: 2002-11-26
Abstract: Imaginograph is an image (18) on a screen which is mathematically gen-eralised optical illusion to create psychological three dimensionality. These pic-tures are the would be "merged images in the brain" produced outside the brain. Rather than cresting one picture for the left eye and another for the right, an Im-aginograph is already the result of the analysed signals. Using the property that when one is looking at a flat picture, the brain superimposes the two substantial-ly the same images (19, 20) in the left and right eyes and produces the same pic-ture (21) in the brain. Imaginographs are pictures which are formed by superim-posing the left and right eye views at the same position as the object of interest in the view, keeping the images of the object of interest in the two pictures in regis-ter at all times. The left and right eye views and their projections can be genera-lised to obtain three dimensional views of non-Euclidean spaces.

Abstract: A cooling apparatus for integrated circuit chips in which the pressure of coolant does not affect is disclosed.          The block is provided with a plurality of holes.  Cooling members are inserted in these holes.  An elastic member is filled between the block and the cooling member.  The cooling member is supported to the block by the elastic member.  Each cooling members is connected each other by pipes.  A bellows is provided between the cooling member and the pipe.  When the block is loaded on the substrate on which the integrated circuit chips are mounted, the elastic member deforms and the cooling member displaces in accordance with the height and inclination of the integrated circuit chip.  The lower surface of the cooling member is brought into close contact with the integrated circuit chip due to the deformation of the elastic member.  The bellows deforms in accordance with the displacement of the cooling member to ensure the normal connection of the pipe.  when the coolant is supplied, the expanded bellows pushes the pipe up but does not push the cooling member down.

Granted: 2004-08-24
Abstract: A rotary air motor has a liner disposed within a tool housing and having a cylindrical bore therethrough. A rotor having radially slidable vanes is eccentrically rotatably mounted in the bore by bearings in the plates of the liner, the vanes cooperating with the rotor and the liner to define a plurality of rotating variable volume fluid compartments.      A fluid inlet port in one end plate communicates sequentially with the fluid compartments. First and second exhaust ports respectively formed in the end plates also communicate sequentially with the fluid compartments, but the two exhaust ports are angularly offset from each other so that the fluid compartments communicate first with the exhaust port remote from the entry end plate and then with the exhaust port at the entry end plate. The exhaust passage from the remote exhaust port passes along the outside of the liner back to the entry end plate, thereby ensuring cooling of both ends of the motor.
