Title: Determination of an analyte in a liquid medium
Inventor: DAGAN ARIE
IPC: G01N33/543
Filed: 1996-07-16
Abstract: Binding between two members of a recognition pair, e.g. antigen-antibody is determined by utilizing a probe comprising a piezoelectric crystal with electrodes on two opposite faces of the crystal. The crystal carries one or more metal plates which may be the same or different than said electrodes, the metal plates having immobilized thereon a first member of a recognition pair. Binding of a second member of the recognition pair to the first member, or dissociation between the two members and release of the second member from the probe, causes a change of immobilized mass which results in a change to the probe's resonance frequency. Said immobilized members may be immobilized on the surface of said metal plates by means of a linking group, having the following general (I): Z-R1-Q wherein Z represents a sulphur-containing moiety which is capable of chemical association with, attachment to or chemisorption onto said metal, R1 represents a connecting group; Q is a functional group which is capable of forming a covalent bond with a moiety of said first member of the recognition pair. The immobilized member may have or be linked to an isomerizable group which changes its isomerization state as a result of exposure to energy.

Title: Angle cock with junction box
Inventor: ENGLE THOMAS H
IPC: B60T17/04
Filed: 1998-03-04
Abstract: The invention provides a railroad brake line shutoff valve assembly for connecting a car-mounted railway brake line to a brake line air hose which is for terminating in a brake line connector which is to be connected to another brake line connector on another vehicle.  The shutoff valve assembly has a stationary valve portion and a moveable valve portion.  The stationary valve portion has a first fluid line attachment site for the car mounted railway brake line and a second fluid line attachment site for the brake line air hose. Movement of the moveable valve portion to one position opens a flowpath through the valve between the first fluid line attachment site and the second fluid line attachment site so that the brake line air hose is connected to the car-mounted brake line. Movement of the moveable valve portion to another position closes the flowpath through the valve.  The valve includes an electrical junction box having a first set of electric line attachment sites  for  connection  of  a  set  of  car-mounted  electrical trainline conductors mounted on the railway vehicle and a second set of electric line attachment sites for connection of a set of electrical line end segments which are for terminating in a multiple contact electrical trainline connector, which is for connection to a similar electrical trainline connector on another railway vehicle. The junction box also has a third set of electric line attachment sites for connection of a branch electric line for connection to at either an electronic system or an electrical system located on the railway vehicle.  Each member of the first set of electric line attachment sites is electrically connected to a corresponding member of the second set  of  electric  line  attachment  sites  and  also  to  a corresponding  member  of  the third  set  of  electric  line attachment sites.

Title: Applicator for dispensing material from a dual chamber cartridge
Inventor: MARTIN THOMAS W
IPC: A61C5/04
Filed: 1996-05-23
Abstract: A dispensing applicator (10) includes a body (14) with a handle (16), a pivotable lever (18) and a front holder (26) with a receptacle (32) that is adapted to removably receive a dual chamber cartridge (12). In certain embodiments, the majority of the cartridge contents are expelled during a single stroke of the lever (18), an advantage when used for single patient use in dental or medical fields. In other embodiments, the holder (26) is rotatably connected to the body (14) so that the holder (26) and the cartridge (12) can be moved as needed in an arc in order to vary the orientation of the cartridge (12) relative to the applicator handle (16). The rotatable connection enables the cartridge (12) to be moved to any one of a number of different orientations as may be desired to provide optimum maneuverability of the applicator (10) in use and to enhance the operator's vision of the application site.
Patent CA-2240015-A1 (CA)
Inventor: SAMRAJ TENNYSON
IPC: A47D13/02
Filed: 1998-07-16
Abstract: A frontal parental attachment for carrying an infant, which is suspended from the shoulders of an adult, and structurally designed from a single-piece, molded, plastic seat with a flexible attached harness at the center. The Polyethylene-molded seat is so shaped so as to provide, not only sufficient space for the baby, but also to provide space for the baby's diapers. The harnesses from the top end swings towards the opposite ends and down to their respective rings where they are snapped into place. The harnesses, attached from the front center, are snapped into the back-ends-under the arms of the baby. The structural strength is engendered by the one-piece polyethylene molded seat created by the rotational molding process. It is designed to be light, and therefore, provides for a parental attachment hardly visible once the baby is in place, and convenient as carry-on luggage to parents. This is a commercially feasible venture to my earlier application.

Title: Methods and apparatus for delivering aerosolized medication
Inventor: MOHSEN NAHED MOHSEN
IPC: A61M15/00
Filed: 1998-07-14
Abstract: A metered dose inhaler for use with a pressurized aerosol canister includes a housing defining a conduit with a mouthpiece, and an actuator with a nozzle discharge orifice arranged to discharge aerosol into the conduit. An air tube is arranged within the conduit with an inlet of the air tube formed in the conduit wall and an outlet of the air tube in opposing relationship with the nozzle orifice. Inhalation through the mouthpiece causes air to be drawn into the inlet and flow out of the outlet of the air tube to form an air jet which impinges on an oppositely moving aerosol plume from the orifice. Auxiliary air inlets in the closed end of the conduit provide a boundary layer flow along the inner wall of the conduit. Vortex generators on the inner wall of the conduit add vorticity and turbulence to the boundary layer flow. Automatic actuation of the canister responsive to the patient's inhalation is achieved by a canister trigger connected to a movable piston assembly forming a wall of a variable-volume chamber in fluid communication with a venturi in the air tube. Air drawn through the venturi by the user's breath causes evacuation of air from the chamber, thereby moving the piston assembly and trigger to cause actuation of the canister.

Title: High voltage generating circuit for volatile semiconductor memories
Inventor: LINES VALERIE
IPC: H02M3/07
Filed: 1998-07-16
Abstract: A high voltage generating circuit which provides a constant V PP output without any threshold voltage drop and which does not suffer from latch-up problems is described. Thus a voltage boosting circuit which provides for a boosted voltage V PP at an output node, from a supply voltage V DD, includes a precharge transistor element responsive to a precharge clock signal for transferring the supply voltage V  DD to a boost node for precharging the boost node to the full supply voltage V DD. The circuit further includes a capacitive element connected between the boost node and a pump node, the capacitive element pumping the boost node in response to a pump voltage signal applied to the pump node; and a switching element connected between the boost node and the output node, for transferring charge from the capacitive element to the output node to provide the boosted voltage V PP. In particular the precharge transistor element is an PMOS transistor. Furthermore in order to prevent latch-up of the PMOS devices, a switching circuit is provided to maintain the substrate at the highest voltage in the circuit.
