Title: Seed dispenser with dual-faced seed plate
Inventor: KEETON EUGENE E
IPC: A01C7/16
Filed: 1989-08-15
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE A  seed  dispenser  for  agricultural planters has a casing forming a seed-receiving chamber  and  within the chamber,  turning  on  a transverse axis, is a seed plate or wheel  having seed-receiving  cells  on  both  radial faces.    The  wheel  is  in  effect a rotating partition which  divides  the   chamber   into   right   and   left compartments.    One  of  the compartments receives seed, as from a hopper, and the wheel has one or  more  through openings   so   that   the   seed   flows  from  the  one compartment to the other.  Both compartments  lead  to  a seed  outlet  through  which  seeds are discharged to the ground,  furrow,  etc.    The  arrangement  doubles   the output  of  seed from the dispenser and thus enables more efficient  planting  according  to  modern   agricultural methods.

Title: Moving coin validation
Inventor: DAW RONALD E
IPC: G07D5/08
Filed: 1989-09-06
Granted: 1994-03-01
Abstract: ABSTRACT          The invention concerns a coin validation system which may operate with a moving coin without the need to stop movement  of  the coin for measurement.  The system includes a coin runway, two coils positioned adjacent the runway, two resonant circuits each coupled to a respective coil and first and second signal monitoring means for each resonant circuit arranged to monitor oscillating signals generated in the respective resonant circuit as the coin moves down the runway.  The coils  are spaced upstream and downstream by a known distance to provide an instantaneous velocity and acceleration independent measurement of the property of the coin being tested, e.g., its diameter.  By comparing monitored signals  it is possible to determine how far one of the upstream coil is the trailing edge of the coin and how far out of the downstream coil is the leading  edge  of  the  coil.   It  is  then  possible  to calculate a parameter dependent of said property of the coin for validation.

Abstract: Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and water insoluble, ethanol soluble ethyl cellulose, and may sometimes preferably also include a water soluble binder, such as polyvinyl pyrrolidone. Such speckles satisfactorily maintain their integrity and identity during processing of the dentifrice after addition of the speckles to a main dentifrice body but on storage, after packaging of the dentifrice in dispensing tubes, soften sufficiently so as to become essentially impalpable to one utilizing the dentifrice in brushing his teeth. Despite such softening the speckles continue to maintain their identity as speckles in the dentifrice. The speckles are especially useful in translucent or transparent gel dentifrices which contain components, such as flavouring and surface active agents, which may controllably soften the speckles on storage.

Inventor: STEPHENSON ROBERT J
IPC: C02F11/00
Filed: 1999-08-05
Granted: 2003-02-27
Abstract: A process for liquefying microorganisms present in biosolids, such as waste activated sludge, generated by municipal or industrial wastewater treatment plants is disclosed. The process includes the step of passing a slurry of the sludge at a high pressure through a nozzle having a restricted flow area to cause liquefication of the microorganisms as they are discharged from the nozzle. The pressure drop across the nozzle preferably exceeds 5,000 psi. At least part of the liquefied microorganisms may be recirculated to the treatment facility to feed nutrients to the wastewater treatment process. Optionally, the liquefied microorganisms may be anaerobically converted to methane and carbon dioxide. For optimum results, the sludge is subjected to pH adjustment and/or maceration prior to being pumped through the high pressure nozzle.

Abstract: A tool for setting or retrieving a packoff between the   casing hanger   and   the   wellhead   utilizes differential area pistons.   The tool has a mandrel which connects to a string of drill pipe.  The mandrel carries a body and is axially movable relative to the body.  A sleeve is carried by the body for connection to the packoff.  A sleeve piston is carried by the body for relative movement relative to the body.  A mandrel piston is carried by the mandrel for movement with the mandrel.  Passages in the body communicate the mandrel piston  with    the  sleeve  piston  and  contain  an incompressible fluid.   Axial movement of the mandrel causes the pressure to increase to drive the sleeve piston downward to  set  the  packoff,  or  in  another embodiment, upward to retrieve the packoff.

Inventor: MYERS JAMES R
IPC: G02B6/44

Granted: 1994-04-19
Abstract: ABSTRACT    A fiber optic canister (20) includes a generally cylindrical bobbin (24) and an optical fiber pack (22) wound thereupon.  The bobbin (24) is formed at least in part from a material having orthotropic coefficient of expansion characteristics, arranged so that the coeffic-ients of thermal expansion of the bobbin (24) are matched to those of the overlying optical fiber pack (22).  The optical fibers have a small longitudinal coefficient of thermal expansion and a larger transverse coefficient of thermal expansion.  The orthotropic material of the bobbin is arranged so that the circumferential coefficient of thermal expansion of the bobbin is near zero, and the axial coefficient of thermal expansion is matched to that of the transverse coefficient of thermal expansion of the optical fiber pack.  The bobbin (24) therefore expands and contracts with changes in temperature at a rate approxi-mating that of the overlying fiber pack (22).  The ortho-tropic material of the bobbin (see Fig. 8) is preferably a composite material (62) of structural fibers (64) in a matrix (66), with the structural fibers arranged in an off-axis manner to yield the required anisotropic thermal expansion behavior.
