Patent CA-2067205-C (CA)
Title: Vaccine and immune serum against drugs of abuse
Inventor: CERNY ERICH H
IPC: A61K39/385
Filed: 1991-01-17
Granted: 2009-10-27
Abstract: Addictive drugs like cocaine, heroin or amphetamines are spreading in an epidemic manner in the western world and are an important factor in the spread of the acquired immune deficiency syndrome AIDS(multiple use of infected needles among drug addicts). The present invention describes a vaccine and immune serum against drugs. The vaccine contains the drug bound to a carrier protein in order to produce antibodies against the drugs in the affected person. The use of the drug in the presence of the antibodies deactivates the drug. The desired drug effect is thus eliminated and the vicious circle between stimulation and application is broken.

Title: Balloon inflator
Inventor: NELSON DAVID C
IPC: F04D25/08
Filed: 1992-06-11
Granted: 2005-06-28
Abstract: A balloon inflator utilizes a bypass motor such that the inflation or working air is separate from the motor cooling air. The intake for the motor cooling and inflation air is separated from exhaust vents to limit any recirculation of the air, assuring that the inflation air be maintained as cool as possible. An impeller is maintained in an involute to achieve the requisiting inflation pressure. A free floating inflation nozzle is maintained within a collar and is adapted for engagement with an output of the involute when inflation activity is desired; otherwise the nozzle is disengaged from the involute allowing the air from the involute to otherwise be exhausted. The motor driving the impeller is selectively interconnected with a half wave rectifier for speed selectability.

Title: Ink container having atmosphere communicating section and recording head
Inventor: KARITA SEIICHIRO
IPC: B41J2/05
Filed: 1992-07-10
Granted: 1998-07-21
Abstract: An ink container free from ink leakage against vibration and a shock and capable of reducing the evaporation of ink far greater than before and solving the problem of an increase in ink viscosity.  Moreover, the ink container is a section for sale whose wrapping at a point of sales can be made inexpensive and simple and is totally constructed less expensively.  Further, the ink container is capable of supplying ink for use with stability in case the ink is miscarried or leaks out and simultaneously or recovering the ink into the ink container.       The container for containing ink has an atmosphere communicating section for making the inside communicate with the outside air, the atmosphere communicating section comprising a plurality of chambers outwardly communicating with each other, and the opening of each chamber is a port relatively smaller than the chamber.          Preferably, the plurality of chambers are located in a direction intersecting a direction from the interior to the exterior and the openings of the plurality of chambers are positioned in such a way that they are shifted from each other.       Recording liquid in a tank is prevented from leaking out via an atmosphere communicating port and this drives away a general feeling of uneasiness on the part of users deriving from the possibility of soiling their hands and clothes.

Patent CA-2077425-C (CA)
Inventor: SAKAI ICHIRO
IPC: F16H59/14
Filed: 1992-09-02
Granted: 1997-03-04
Abstract: In a control system for controlling a gear ratio of a multi-step geared or continuously variable automatic trans-mission, the driver's intention to decelerate is inferred by carrying out a first fuzzy reasoning using a degree of throttle opening or the like and then the target gear ratio is determined by carrying out a second fuzzy reasoning using parameters including the inferred driver's intention to decelerate.  The first fuzzy reasoning is carried out using fuzzy production rules classified by operating conditions such as a road profile and a vehicle speed.   The inferred driver's intention to decelerate is canceled if braking is discontinued.  Thus the control ascertain the intention of the driver and is thus possible to achieve sophisticated shift scheduling well matched to the sensibilities of the driver.

Title: Mechanical end face seal
Inventor: WASSER JAMES R
IPC: F16J15/40
Filed: 1993-05-31
Granted: 2004-02-24
Abstract: A double, back to back oriented mechanical end face seal for use in sealing toxic or corrosive fluids having an intermediate buffer fluid chamber into which a relatively inert gas, such as nitrogen, is provided for use as a buffer fluid.      The nitrogen gas is maintained at a pressure which exceeds the process fluid pressure by at least 10 p.s.i. and, in a preferred embodiment, spiral pumping grooves in the mating rings of each of the seals are shaped and dimensioned to pump the nitrogen buffer gas through the first seal from the intermediate chamber into the process fluid chamber and through the second seal from the intermediate chamber into the environment external to the housing and sealing area, thereby avoiding the escape of the process fluid into the intermediate buffer chamber and to the atmosphere.      Contamination of the process fluid by the buffer gas may be tolerated. The buffer gas may be any relatively inert gas, a gas which is non-hazardous to the environment and also, is compatible with he process fluid used; appropriate examples are nitrogen, carbon dioxide; air or one of the noble gases. The seal can be used to seal a process fluid which is either a liquid or a gas.

Title: Implement caster wheel
Inventor: HONEY GREGORY J
IPC: A01D41/14
Filed: 1995-06-05
Granted: 1999-08-31
Abstract: A mounting assembly of a gauge wheel for an implement, such as an agricultural crop harvesting header, the mounting assembly including a king pin member rotatably mounted in a king pin bushing housing and having a wheel spindle projecting substantially horizontally from one side of a king pin shaft for rotatably mounting the gauge wheel. The rotational axis of the king pin shaft is tilted rearwardly and upwardly relative to the vertical and sideways and upwardly relative to the verticalin a direction opposite to the side of the projecting wheel spindle. Accordingly, when the gauge wheel enters a caster turn in a direction corresponding to the direction of projection of the wheel spindle the axis of the wheel spindle swings from a substantially transverse direction in relation to the straight ahead travel direction towards a rearwardly and downwardly inclined orientation. A spring is arranged to bias the king pin shaft to turn in a direction counter to a caster turn, and stops are provided to limit the rotation of the king pin shaft between a substantially straight ahead travel condition and a caster turn of a preselected amount of turn. Effective castering of a gauge wheel at the inside of a turn is accomplished together with good straight ahead stability. The structure also allows positioning of the castering gauge wheel close to the framework of the header.

Title: Methods and fluids for removal of contaminants from surfaces
Inventor: BORAH RONALD E
IPC: C11D3/20
Filed: 1994-04-04
Granted: 2001-01-02
Abstract: A cleaning process and water-based cleaning compositions effective for the removal of radionuclides, polychlorinated biphenyls, pesticides, herbicides, and heavy metals from surfaces of all types, more especially porous surfaces, surfaces that contain irregularities and microspcopic voids into which contaminants may migrate and lodge thereby creating a substrate below the surface that must also be cleaned, and particulate surfaces. The cleaning blends and processes remove contaminants from porous and irregular surfaces to such a depth below the surface and into the substrate, and to such an extent, that the cleaned surface satisfies current regulations promulgated by the EPA and NRC relating to standards for decontamination. The process also allows sealing of cleaned surfaces, if desired, with an impermeable coating of a synthetic polymeric composition in order to retard subsequent migration of any residual contaminants to the surface.
